Vampire Clinic That Sold Young Blood to the Wealthy Closes Shop

Bad Blood

Ambrosia Health, the controversial clinic that sold transfusions of young, healthy people’s blood, has “ceased patient treatments,” according to the company’s website.

The decision to stop taking patients comes after an official statement from FDA commissioner Scott Gottlieb this week, which described the company’s practices as a dangerous scam.

Dr. Acula

Ambrosia claimed its transfusions of a younger person’s blood could reverse health problems and extend a person’s life — a controversial and unproven notion.

The company never published the results of its self-funded clinical experiments, and recent evidence suggests that these transfusions could have been dangerous from the start.

Vampire Empire

It’s unclear whether Ambrosia plans to resume operations in the future or if the FDA’s warning rang the company’s death toll. Futurism reached out to the company with questions, and this article will be updated if we hear back.

Either way, the wealthy will need to get their controversial medical treatments somewhere else for the time being.

Bangladesh Declares “War on Pornography,” Blocks TikTok

The Bangladeshi government is scrubbing the internet of porn. But it's also monitoring people's personal social media accounts for provocative images.

Porn Ban

Over the past week, Bangladesh has blocked tens of thousands of sites and apps and is policing the social media accounts of celebrities in an effort to scrub the nation’s internet of pornography.

The porn purge comes as part of the government’s push to crack down on adult-oriented content like porn and gambling, which originated with a November decision in Bangladesh’s High Court, according to Al Jazeera.

Declaring War

“I want to create a safe and secure internet for all Bangladeshis, including children,” said Mustafa Jabbar, Bangladeshi posts and telecommunications minister. “And this is my war against pornography. And this will be a continuous war.”

That war on porn also seems to involve micromanaging the lives of celebrities. The Bangladeshi government recently ordered a local actress to delete what it determined were provocative pictures from her various social media accounts, Al Jazeera reports.

“We are monitoring the local Facebook profiles, YouTube channels and websites, also,” Jabbar said. “A few of them were taken down for having obscene content. We advised a few others not to post anything that goes against our social norms.”

Behind Seven Proxies

So far, internet service providers have complied with the government’s demands. But the nation’s porn hungry internet users can still access porn with a little technological wizardry.

A Bangladeshi official confirmed that the country’s new regulations can be skirted using a virtual private network or mirror websites, according to Al Jazeera.

New Research: Earth’s Atmosphere Extends Well Beyond the Moon

Data collected by NASA and ESA's Solar and Heliospheric Observatory reveals that Earth's gaseous layer extends up to 391,000 miles away from Earth.

The Geocorona

A light layer of hydrogen atoms called the geocorona separates Earth’s atmosphere from outer space. And it extends far beyond Earth — much farther than previously believed.

Data collected by NASA and the European space agency’s Solar and Heliospheric Observatory (SOHO), a spacecraft that launched in 1995 to study the Sun, suggests that this gaseous layer extends up to 391,000 miles (630,000 km) from Earth — which, strikingly, is 50 times Earth’s diameter and almost twice the distance to the Moon.

Water Vapor

And that’s a big deal, because planets with traces of hydrogen in their atmospheres have a much higher chance of containing water on the surface.

“This is especially interesting when looking for planets with potential reservoirs of water beyond our Solar System,” explained Jean-Loup Bertaux, co-author of the paper on the new research and former principal investigator at ESA, in an official press release.

Empty Space

Unfortunately, those extra hydrogen atoms won’t be particularly useful for future missions to the Moon.

“On Earth we would call it vacuum, so this extra source of hydrogen is not significant enough to facilitate space exploration,” said Igor Baliukin of Russia’s Space Research Institute and lead author of the paper.

But they could make future astronomical observations more accurate by allowing astronomers to take the hydrogen atoms and their associated ultraviolet wavelengths into account.

The revelation symbolizes a big win for the SOHO team. “This discovery highlights the value of data collected over 20 years ago and the exceptional performance of SOHO,” said Bernhard Fleck, SOHO project scientist at ESA.

EPA: Low Doses of Toxins, Radiation Could Actually Be Healthy

The EPA has proposed a rule change that would trade a cautious approach to regulating low-doses of chemicals for one that's far more flexible. 

Toxic Changes

In April, the Environmental Protection Agency (EPA) proposed new standards for how it studies the health impacts of low doses of chemicals, trading in a previously cautious approach for one that’s far more flexible.

On Tuesday, the Los Angeles Times published a deep dive into the work that went on behind the scenes to get this proposed rule change added to the Federal Register — and the damage it could do to public health if adopted.

Current Standard

For decades, according to the LA Times’ excellent explainer, U.S. federal agencies have adhered to what’s known as the linear no-threshold model when regulating and studying toxic chemicals and radiation. This model assumes that if a substance is harmful at any level, it’s harmful at all levels, with the level of harm increasing or decreasing depending on the level of exposure.

This model ensured that the public wouldn’t be exposed to potentially harmful substances even if research didn’t conclusively prove that a low level of exposure would, in fact, be harmful.

That was important because, in some cases, various studies of the same chemical at the same low dose have reached different conclusions. One might assert that the low dose is harmful, another that it has no effect, and still another that the dose is actually beneficial to the human body, a phenomenon known as hormesis.

Hormesis D’oeuvre

It’s true that some dangerous substances really are beneficial at low doses. Small doses of tamoxifen, for example, can help treat breast cancer, but at higher doses, the chemical can actually cause uterine cancer.

However, while hormesis might be useful in a clinical setting, it’s not an effective way to regulate chemicals that could reach the public at large, according to David Jacobs, a public health professor at the University of Minnesota.

“There is no way to control the dose a person gets from an industrial or agricultural chemical,” Jacobs told the LA Times. “It’s not being doled out in pills and monitored by a physician who can lower it if the patient isn’t responding well.”

The Holy Grail

On April 30, the EPA posted a proposed rule titled “Strengthening Transparency in Regulatory Science” for comment in the Federal Register. It removes linear no-threshold as the default model for estimating low-dose impacts, instead giving the EPA the authority to test other models, including hormesis.

Ten months later, the EPA has yet to announce a final date for deciding on the proposed rule. But if it’s adopted, public health experts told the LA Times they expect it to “tie the EPA up in knots” and possibly even result in new standards for everything from our air to our drinking water.

“Industry has been pushing for this for a long time,” David Michaels, a professor of environmental and occupational health at George Washington University, told the newspaper. “Not just the chemical industry, but the radiation and tobacco industries, too.”

“This is industry’s holy grail,” he concluded.

Elon Musk: Teslas Will Be Fully Self-Driving By Next Year

Full Autonomy

According to Elon Musk, Tesla’s cars are nearly ready for fully autonomous driving.

“I think we will be feature complete — full self-driving — this year,” Musk told Cathie Wood and Tasha Keeney of ARK Invest in a podcast on Tuesday. “Meaning the car will be able to find you in a parking lot, pick you up and take you all the way to your destination without an intervention, this year.”

Car Naps

By next year, you’ll be able to take a nap behind the wheel, Musk claimed in the same interview.

“My guess as to when we would think it is safe for somebody to essentially fall asleep and wake up at their destination? Probably towards the end of next year,” he said.

And he’s willing to stand by his words: “I would say I am of certain of that,” he said. “That is not a question mark.”

Big Promises

Musk is no stranger to making big promises. As it stands right now, Tesla’s Autopilot can make lane changes, and navigate highway ramps — but it still can’t handle most other roads.

In October, Tesla dropped the “full self-driving” mode from the Model 3, with Musk claiming it was “causing too much confusion” in a tweet.

The race to have cars take over all driving functions is on. Alphabet’s Waymo launched a robo-taxi service in Arizona in December.

But even Waymo’s cars require human safety drivers to take control on multiple occasions throughout a single ride.

Automakers Could Give Police Control Over Your Self-Driving Car

The relationship between law enforcement and self-driving cars is still in flux, but some are suggesting we give let police control self-driving cars.

More Q’s Than A’s

We still have a lot of questions to answer before autonomous vehicles can go mainstream: Who’s at fault if an AV has an accident? Should people need licenses to ride in a self-driving car? How should an AV decide between running over a dog or a cat?

On Wednesday, Bloomberg published a story focused on yet another question — how should AVs interact with law enforcement? — and the solution might involving ceding control of your car to cops.

Police Power

The Bloomberg story notes the Dec. 2018 incident in which an intoxicated driver fell asleep behind the wheel of a Tesla with Autopilot engaged. The vehicle led police on a seven-minute chase down a freeway before officers were able to compel the Tesla to stop by essentially boxing it in.

This is the kind of problem AV manufactures and law enforcement want to avoid, and that could mean programming AVs to pull over as soon as they detect flashing police lights behind them, a protocol already adopted by Waymo.

Bloomberg even suggests that officers forced to exit their vehicles might be able to instruct other AVs to reroute away from an area “with a couple of taps on a handheld device.”

Driver Rights

Letting law enforcement control a car presumably owned by a citizen seems like murky legal territory.

Even if legal, it would be easy to see how some people might be opposed to police being able to give instructions to their car — especially if the car is programmed to follow police orders over that of the driver and the driver isn’t doing anything illegal.

Some critics have also noted how hackers might be able to exploit any ability for police to control AVs.

It’s still too early to say whether any of the measures proposed in the Bloomberg piece will become the standard for navigating interactions between AVs and law enforcement. But given that we could have fully autonomous vehicles as soon as next year, we have no time to waste figuring out an answer to this lingering question.

Samsung Just Revealed a $1,980 Folding Smartphone

Galaxy Fold

Korean tech giant Samsung officially announced its take on the growing foldable smartphone trend at its Galaxy Unpacked event today in San Francisco: the Samsung Galaxy Fold. The device will go on sale for $1,980 on April 26.

We first got a glimpse of the device in November, but the brand has likely been working on the concept for almost half a decade.

Serious About Multitasking

The Galaxy Fold will unsurprisingly pack some serious power, with a high resolution 7.3-inch Infinity Flex Display. When it’s folded in half — Samsung referred to that as “phone mode” — the display size is reduced to only 4.6 inches.

It’ll also pack an impressive 12 GB of RAM and 512 GB of on-board flash storage.

Foldable Future

Competitors include Royole and Chinese phone maker Xiaomi. The latter is developing a smartphone that folds on both sides, like a birthday card.

The device seems to be a little awkward to use in phone mode, but when unfolded, the Galaxy Fold could be a worthy replacement for a seven-inch tablet.

Scientists Used Gene Therapy to Cure Deafness in Mice

A new gene therapy tested on mice can treat a specific kind of congenital deafness by repairing a faulty inner-ear protein.

Three Deaf Mice

About half of the time someone is born totally deaf, it’s because of their genetic makeup. Those people are typically treated with cochlear implants, but now researchers from Europe and the U.S. are looking at gene-based treatments as well.

Deaf mice treated with a new kind of gene therapy developed the ability to hear almost as well as healthy mice, according to research published Tuesday in the journal PNAS — findings that suggest gene therapies may someday help with previously-untreatable conditions.

Ear Genes

The mice had what’s called DFNB9 deafness, the type that accounts for between two and eight percent of gene-related cases of human deafness. In DFNB9 deafness, a protein called otoferlin can’t perform its usual role of transmitting sound information gathered by the fine hairs in the inner ear.

But after altering the deaf mice’s genomes with specially-crafted viruses, the mice were able to hear almost as well as mice that were born with functioning otoferlin.

Step One

Even after altering the same specific gene in mice as what causes DFNB9 deafness in humans, it’s too soon to say that these gene-editing viruses can be used to treat people. There’s a long road between animal experiments and human clinics.

There’s more reason to be wary of this treatment. According to a conflict of interest statement in the PNAS article, one researcher from the University of Florida stands to profit if this virus-based technology takes off — so it’s worth waiting to see if the work holds up in further studies.

Lawyer: People Could Try to Sell the Apollo Moon Footprints

Air and Space Law professor Michelle Hanlon argues that if we don't draft new laws, the destruction of landmarks that happens on Earth will repeat in space.

Interplanetary Heritage

Right now, there’s no legal framework preventing people from destroying or selling culturally-important landmarks in space.

For instance, as space travel becomes more common, an opportunistic someone could find a way to steal and auction off the first bootprints left on the moon by Neil Armstrong, warns University of Mississippi Air and Space Law professor Michelle Hanlon in an essay published Friday in The Conversation.

Earthly Precedent

Hanlon cites damage to landmarks like the Pyramids of Gaza or Terracotta Army by tourists who break off pieces to take home as evidence that people can’t be trusted to preserve landmarks of their own volition.

“There is no law against running over the first bootprints imprinted on the moon,” Hanlon wrote. “Or erasing them. Or carving them out of the moon’s regolith and selling them to the highest bidder.”

Rising Chorus

Places like Stonehenge and ancient cave paintings are protected as part of the U.N.’s World Heritage List. If landmarks in space are to survive as more nations and companies develop the capacity to leave the planet, Hanlon believes that leaders need to be proactive and protect those landmarks before anything goes wrong.

Hanlon is just one of many to recently call for more comprehensive or updated space laws. Right now, the various laws and treaties that pertain to outer space are a bit of a mess. Hopefully, before trips to the moon become commonplace, someone can sort them out.

What are Nootropics? – Neurohacker Collective

Nootropics. You might have heard of them. The limitless pill that keeps Billionaires rich. The smart drugs that students are taking to help boost their hyperfocus. The cognitive enhancers that give corporate executives an advantage. All very exciting. But as always, the media are way behind the curve. Yes, for the past few decades, cognitive enhancers were largely sketchy substances that people used to grasp at a short term edge at the expense of their health and well being. But the days of taking prescription pills to pull an all-nighter are so 2010. The better, safer path isnt with these stimulants but with nootropics. Nootropics consist of dietary supplements and substances which enhance your cognition, in particular when it comes to motivation, creativity, memory, and other executive functions. They play an important role in supporting memory and promoting optimal brain function.

These days, nootropics are beginning to take their rightful place as a particularly powerful tool in the Neurohackers toolbox. After all, biochemistry is deeply foundational to neural function. Whether you are trying to fix the damage that is done to your nervous system by a stressful and toxic environment or support and enhance your neural functioning, getting the chemistry right is table-stakes. And we are starting to get good at getting it right. Whats changed?

A big part is that we are finally starting to apply complex systems science to psycho-neuro-pharmacology and a nootropic approach. The neural system is awesomely complex and old-fashioned reductionist science has a really hard time with complexity. Big companies spends hundreds of millions of dollars trying to separate the effects of just a single molecule from placebo and nootropics invariably show up as stacks of many different ingredients (ours, Qualia , currently has 42 separate synergistic nootropics ingredients from alpha GPC to bacopa monnieri and L-theanine). That kind of complex, multi pathway input requires a different methodology to understand well that goes beyond simply whats put in capsules.

But, thanks to the efforts of a number of remarkable scientists, researchers and plain-old neurohackers, we are beginning to put together a whole systems model of how all the different parts of the human brain work together and how they mesh with the complex regulatory structures of the body. Its going to take a lot more data and collaboration to dial this model in, but already we are empowered to design stacks that can meaningfully deliver on the promise of nootropics to enhance the quality of subjective experience and promote cognitive health, while having extremely low toxicity and possessing very few side effects. Its a type of brain hacking that is intended to produce noticeable cognitive benefits.

Before taking any supplement or chemical, people want to know if there will be long term effects or consequences, When Dr. Corneliu Giurgea first authored the term nootropics in 1972, he also outlined the characteristics that define nootropics. Besides the ability to benefit memory and support the cognitive processes, Dr. Giurgea believed that nootropics should be safe and non-toxic.

While some people focus on finding a short-term boost, nootropics emphasize long-term effects with noticeable cognitive support over a more extended period. Even though nootropics are intended to be safe, there are a few issues users want addressed before taking these supplements.

Many nootropics promote cognitive functioning as well as cognitive performance. Dr. Giurega also saw improved memory and reduced stress in many patients as well.

The first concern users have is with developing a tolerance to the nootropic. Developing a tolerance means the more you have of a substance, the less effective it gets over time.

Second, users are concerned with the possibility of withdrawal if they stop taking the nootropics. They worry that if they stop taking nootropics they wont be as smart as when they were taking nootropics, and will need to continue taking them to function. Some users report feeling a slight brain fog when discontinuing nootropics, but that isnt a sign of regression.

One of the most common strategies to beat this is cycling. Users who cycle their nootropics take them for a predetermined period, (usually around five days) before taking a two-day break from using them. Once the two days are up, they resume the cycle. By taking a break, nootropic users reduce the tolerance for nootropics and lessen the risk of regression and tolerance symptoms.

With so many different ones to choose from, choosing the best nootropics for you can be overwhelming at times. As usual, a decision this important will require research. Study up on the top nootropics which catch your eye the most. The nootropics you take will depend on what you want the enhancement for. The ingredients within each nootropic determine its specific function. For example, some nootropics contain ginkgo biloba, which can help memory, thinking speed, and increase attention span. Check the nootropic ingredients as you determine what end results you want to see. Some nootropics supplements can increase brain chemicals such as dopamine and serotonin. An increase in dopamine levels can be very useful for memory, alertness, reward and more. Many healthy adults, as well as college students take nootropics. This really supports the central nervous system and the brain.

Another factor to consider is whether the nootropic is natural or synthetic. Natural nootropics generally have effects which are a bit more subtle, while synthetic nootropics can have more pronounced effects. Its also important to note that there are natural and synthetic nootropics. Some natural nootropics include Ginkgo biloba and ginseng. One benefit to using natural nootropics is they boost brain function and support brain health. They do this by increasing blood flow and oxygen delivery to the arteries and veins in the brain. Moreover, some nootropics contain Rhodiola rosea, panxax ginseng, and more.

Some nootropics are more commonly used than others. These include nutrients like Alpha GPC, huperzine A, L-Theanine, bacopa monnieri, and vinpocetine. Other types of nootropics ware still gaining traction. With all that in mind, to claim there is a best nootropic for everyone would be the wrong approach since every person is unique and looking for different benefits.

Even the best of todays nootropics only just barely scratch the surface. You might say that we are in the Nokia 1100 phase of taking nootropics, and as better tools and more data come along, the leading thinkers in the space see a powerful future. For example, they are already beginning to look past biochemistry to the epigenome. Not only is the epigenome the code that runs much of your native biochemistry, we now know that experiences in life can be recorded in your epigenome and then passed onto future generations. There is every reason to believe that you are currently running epigenetic code that you inherited from your great-grandmothers life experiences. And there is every reason to believe that the epigenome can be hacked that the nootropics of the future can not only support and enhance our biochemistry, but can permanently change the epigenetic code that drives that biochemistry and that we pass onto our children. This is why many healthy individuals use nootropics. They have great benefits and can promote brain function and reduce oxidative stress. They can also improve sleep quality.

What are Nootropics? - Neurohacker Collective

Nootroo 5.0 The Gold Standard in Nootropics

Nootroo 5.0 - The Gold Standard in Nootropics - Nootroo

Nootropics have been shown to enhance the learning ability of healthy adults.

The brain is more able to process and recall verbalized words if nootropics were administered prior.

Increase Memory Formation

Memory formation is facilitated by the presence of nootropics in the brain.

Greater Interconnectivity

The amount of information passing between hemispheres of the brain is significantly increased by nootropics

Enhance Learning & Memory

Improve learning acquistion and enhance resistance to learning impairments from casues such as lack of oxygen (hypoxia), electroconvulsive shock (ECS), and chemicals that tend to prevent memory formation (scopolamine).

Facilitate Interhemispheric Transfer & Synchronization

Facilitate the transfer of information from one hemisphere to the other, across the corpus callosum which increases synchronization between the hemispheres.

Non-Stimulant & Non-Sedative

Work by increasing the integration of higher-level (telencephalic) activity. On over 30 classical pharmacological tests, the original nootropic shows no activity, including as neither a central nervous stimulant nor a sedative.

Enhance Cerebral Resistance

Increase the brain's ability to resist aggressions and increase recovery time after loss of oxygen, physical trauma, and many chemical intoxications.

StrengthenControl of SubcorticalProcesses

While not acting on directly the central nervous system, nootropics are still able to modulate cortical tonic control, as seen in central nystagmus and spinal fixiation.

Non-Toxic & Low-to-No Side Effects

Must work in harmony with the brain, being virtually free of side-effects and non-toxic even in high doses. Nootropics must not be habit-forming or cause withdrawal.

The nootropic concept had to be developed because a molecule was discovered that had properties unilke anything before it. This molecule, now known as Piracetam, was able to enhance learning and memory while being protective of the brain, and had little to no side effects.

Piracetam was the prototype for the nootropic concept and forms the greatest body of evidence on the efficacy of nootropics. The Nootroo Gold and Silver Formulas are based off of this research and include next-generation, more advanced versions of piracetam each stacked synergystically with citicoline (Cognizin).

The term nootropics is derived from the Greek words for mind and towards and means towards the mind. Nootropics are molecules that have a selective activity upon the higher-integrative mechanisms of the brain. They act directly on the parts of the brain where information is brought together on the highest level and as such are able to positively enhance the processes related to learning, speech, and memory acquisition, consolidation, and recall. To be considered a nootropic, these properties of enhanced activity must occur while also being protective of the brain and while having little to no side-effects.

In 1964, scientists in Belgium were working to develop a sleep-aid. The scientists modified the naturally occurring neurotransmitter GABA, but what resulted instead of a sleep-aid, was something much more profound, a molecule that would come to be known as piracetam. As they probed the properties of the molecule, it became increasingly clear that it was so unqiue, that an entirely new category would be required to describe it, and so in 1972, Cornlieu Giurgea proposed the nootropic concept.

Nootroo Gold & Silver is our premium nootropic stack based on the continued research into nootropics over the last 50 years. The Gold and Silver Formulas each have a different main, next-generation nootropic paired with the precursor for the memory neurotransmitter. The Gold Formula contains Noopept and Citicoline (Cognizin) and the Silver Formula contains Phenylpiracetam and Citicoline (Cognizin). Each bottle contains 30 total pills, with 15 of the Gold Formula and 15 of the Silver Formula and can be distinguished by their non-artifically colored capsules. We are now shipping our 5.0 version of Nootroo Gold & Silver Formulas.

The combination of the ingredients in both the Gold & Silver Formulas are considered to besynergistic stacks. Research shows that the underlying mechanism of the combination has a profound effect on memory enhancement. Citicoline administration alone in healthy adults alone increases the levels of the main neurotransmitter responsible for memory formation, acetylcholine in the outside areas of the brain. When combined with piracetam-like nootropics, the increased acetylcholine is brought into the hippocampus where it is more fully utilized by the brain. The combined effects of nootropics+choline are greater than either alone.

Founded in 2014, Nootroo is dedicated to creating the highest quality nootropic stacks available. Our tagline is The Gold Standard in Nootropics because of our commitment to using only the highest possible quality ingredients. In fact, that tagline (and our gold branding) comes from the fact that we used to use actual 23.5k gold flakes in our Gold Formula and 100% pure silver flakes in our Silver Formula to distinguish betwen them, before we manufactured our custom, non-artifically colored capsules. Our commitment to quality goes beyond aesthethics though, as we are commited to making sure everything else in the capsules is pure as possible. We carry out 3rd-party lab testing on all of our ingredients with a spec of 99% purity and A+ ratings, and we license the purest form of citicoline, a patented bioidentical form from Japan called Cognizin. Our capsules also contain no binding agents, fillers, excipients or anything besides the high-purity ingredients listed. With Nootroo you can be confident knowing that we never cut corners and that you always have the best nootropics available.

Understanding the Original Nootropic: Piracetam

Piracetam was shown to significantly increase the memory of healthy college students in less than 14 days of daily use on a word recall test. Nootropic effects generally increase over time and this study concluded that nootropics are "capable of extending the intellectual functions of man."

Healthy adults had a 15% increase in the number of words recalled on a test of verbal recall. Words heard by the left ear had to cross the corpus callosum in order to reach the verbal processing region on the other side of the brain in order to be verbalized.

Piracetam is not a stimulant and does not work by directly affecting the central nervous system as caffeine or an amphetamine does. Piracetam shows no activity on over 30 different tests and has demonstrated little to no side-effects, including no toxicity, even in extremely high doses.

Next-Generation Nootropics

While piracetam is an amazing molecule, its accidental discovery meant that it wasn't invented with a directed focus on cognitive enhancement or neuroprotection. Fortunately, in the intervening decades since piracetam's discovery, research labs around the world set out to make improved versions with additional benefits and they succeeded beyond their expectations. Two of the best versions created were noopept and phenylpiracetam.

Noopept is a di-peptide version of piracetam that has very high bioavailability and demonstrated anxiolytic properties. Phenylpiracetam was created by adding a "phenyl" group to piracetam which gives it increased bioavailability and some psychomotor activity.

The circles below show where the piracetam structure is within these new molecules. Taking these advanced forms of piracetam and adding a bio-identical form of the body's preferred choline source is how you get the Nootroo Gold & Silver Formulas.

Noopept is a di-peptide version of piracetam specifically developed to be more powerful and absorbable from oral administration. The researchers from the lab that created it, specialized in creating peptide versions of other molecules, and created hundreds of modified versions of piracetam before selecting Noopept because it is was highly absorbed and "demonstrated a wide spectrum of cognition improving effects." This molecule has been demonstrated to have both positive short-term and long-term effects at enhancing memory and mental processing, especially in older populations.

In adults with (a) cognitive decline and (b) post-concussional syndrome, Noopept was shown to have an even more powerful and consistent effect compared to piracetam.

Noopept significantly increased the brain-derived neurotrophic factor (BDNF) in the brain. BDNF levels control the quantity of new neurons created by the brain.

Noopept has been shown to increase the firing rate of pyramidal neurons in the hippocampus. These neurons are implicated in memory formation and recall.

CDP-Choline, as will be discussed more in depth down below, is the bodys preferred precursor for the memory neurotransmitter acetylcholine. Supplementation of acetylcholine alone will increase acetylcholine production in the brain. Nootropics alone will increase the bodys use of acetylcholinein the process of forming memory. So when combined, the power of this increased supply to meet the brains increased neurochemical demands, has been shown to have profound effects compared to either alone.

Phenylpiracetam is a version of piracetam with an added phenyl group designed to increase processing speed and provide mental endurance. This added group increases piracetam's affinity for the receptors that control psychomotor activity (where movement and thinking are combined), while not not being a central nervous stimulant. Phenylpiraceatam has been shown to significantly speed up processing and endurance, even in single doses. It was utilized by the Russian space program for use by cosmonauts on extended missions.

Phenylpiracetam was shown to increase the amount of distance covered in exploratory trials. This correlates to an increase in mental activation and endurance.

Phenylpiracetam was shown in this study to regulate the brain waves against aggression in an epilepsy model. Autonomic normalization is a property that helps ensure consistent brain activity against things that would tend to disrupt it.

Phenylpiracetam has also been shown to prevent a memory blocking agent, scopolamine, from blocking memory formation. This is a powerful indicator of the effect of phenylpiracetam on memory formation.

One way phenylpiracetam works,is by activating and enhancing the activity of the cholinergicsystem in the brain. The cholinergic system modulates memory and learning and in order for it to operate optimally, it needs the molecule acetylcholine to be at certain levels in synapses. CDP-Choline is the precursor for acetylcholine, and by adding it to the body, the brain will increase its choline levels. By increasing the amount of choline available, the brain will then utilize more of it and in doing so, will enhance the firing mechanisms of this system. This allows phenylpiracetam to have an optimized cholinergic system to interact with.

CiticolineIn Gold & Silver Formulas:

CDP-Choline, also known as citicoline, is a precursor for the memory neurotransmitter acetylcholine. Supplementation has been shown to increase acetylcholine production in the brain. Citicoline administration has also been shown to increase brain bioenergetics by increasing energy reserves and utilization of energy.. Studies in healthy adult women show that taking Cognizin citicoline significantly improved their verbal memory after just 28 days. Studies suggest that citicoline also can help increase dopamine receptor densities , which is the neurotransmitter associated with motivation. We license Cognizin, a patented form of Citicoline, that is the only pure, free-base form of citicoline that is bioidentical to the form found in nature.

Healthy adult women taking CDP-Choline have been shown to have an improvement in memory and focus after 28 days.

The levels of the energy carrier molecule (ATP) were increased by 13.6% by CDP Choline and cell membrane turnover was increased by more than 25%.

CDP-Choline alone in adolescent males for 28 days was shown to significantly increase psychomotor speed and improve attention compared to placebo.

CDP-Choline is an essential nutrient that is crucial in the brains processes of memory formation, attention and learning, yet most people are deficient in it. CDP-Choline is typically obtained by the body from food and supplies choline for the brain to make the neurotransmitter acetylcholine as well as neuronal cell membranes. That is why simply adding it to the body results in a >25% increase in cell membrane formation as well as >10% increase in cellular energy (ATP) levels. The recommendations for adults is between 450-550 mg per day, both Nootroo Gold & Silver have approximately 500 mg of the purest form of CDP-Choline available, Cognizin branded CDP-Choline. It is made in an enzymatic process in a bioreactor that takes 6 months and is imported from Japan. This patented-form of CDP-Choline is the only form that is bioidentical to the form found in nature, in a free-base and not a salt.

Humanity will not wait millions of years until Mother Nature will hand it a functionally better brain...[Humankind] will directly, openly and consciously take part in evolution.

In the early 1960s, scientists were working to develop a form of the neurotransmitter GABA, that would be able to cross the blood-brain barrier and potentially work as a sleep aid..

While they succeeded in developing a molecule with the ability to enter the brain, they failed at creating a sleep aid. What they discovered instead, however, was a molecule that would later prove to be much more profound.

Like a sculptor removing parts of the stone to reveal the beauty within, Corneliu Giurgea, the lead scientist at the lab, and his team would work diligently to chip away at the unknowns of piracetam, to reveal the properties within it.

After 9 years of research, Giurgea had determined that this molecule (piracetam) acted in such a unique way on the higher-level, integrative activities of the brain, that in order to classify it, the creation of an entirely new classification was required: " the nootropic approach to integrative activity of the mind."

On over 30 pharmacological tests, Piracetam was found to have no activity, including being neither a sedative nor a stimulant. It also had no toxicity and few side effects, even when given in extremely high doses, such as grams per kilogram of body weight, to mice, rats, cats, dogs, and monkeys with single or multiple doses, even over long-term administration.

In fact, because of those properties, piracetam seemed to be inactive. Had it not been for a test on nystagmus (involuntary eye movements), where they found it immediately active, piracetam likely would have been passed over. This discovery was especially intriguing to the researchers because all of the then-known agents active against nystagmus were either antihistamines or anticholinergics.

It was clear that piracetam did not fit into either of those classes, so the researchers set out to understand which class it did fit into. As they would eventually discover, no existing class embodied the properties of this "unusual" molecule.

The first human trials began in 1965 and showed that piracetam was able to significantly inhibit nystagmus. Because there was extremely low toxicity and seemingly few side-effects, they began to test piracetam in other populations. Further data reported internally then claimed "fairly good efficacy against motion sickness and vertigo" in humans. These findings lead them to search for a "more comprehensive picture of piracetam from the neurophysiological point of view."

As they were carrying out these follow up studies over 1966-1967, a series of surprising results were reported. First, results came in from a study done at a hospital in Finland on post-concussion patients. The scientists running the study wrote to Giurgea to let him know that the "patients memory seemed somehow improved, that they declared to 'think' better.".

Then came word from a trial in Brusseles on epileptic children administered piracetam. The parents of the children in the study "claimed a kind of improvement in the overall mental efficiency." And then another researcher reported to him that his Parkinsonian patients under Piracetam were "somehow more aware of their sickness."

Since Giurgea and his team had previously demonstrated piracetam selectively enhanced interhemispheric communication (see associated image), he had suspected that the compound might facilitate other cortically integrated mental functions, but at that time, he had no idea the extent.

This new information changed the course of their clinical work and they began to focus on "studies related to a potential beneficial effect of Piracetam on mental activity."

Nootropic Properties Revealed

As experimental data on the neurochemical mechanisms of piracetam continued to expand, Giurgea and his team began to zero in on some overarching properties of the molecule that would come to define the nootropic class.

In normal subjects, piracetam appeared to "activate efficiency of higher nervous function" and in the case of injury, piracetam appeared to "protect and/or facilitate restoration of normal brain activity."

From these observations and others, Giurgea surmised that piracetam, and potentially other molecules like it, "appeared to have a selective activity upon the higher-integrative mechanisms of the brain."

Enhancement of Learning & Memory

Rats learned how to exit a water maze much more quickly when on piracetam.

Facilitation of Interhemispheric Transfer

Notice the change in the amplitude of the evoked potential of the corpus callosum, without a change in morphology. Demonstrating telencephalic selectivity.

Protection Against Loss of Oxygen

Memory is protected from disruption during a loss of oxygen (hypoxia) if the rats are given Piracetam prior.

Protection From Electroconvulsive Shock

After having their brains electroconvulsively shocked, after 24-hours, rats given piracetam prior remembered 100%, while rats on placebo remembered less than 20% of the time.

Nootropics | HVMN Biohacker Guide

Nootropics are a broad classification of cognition-enhancing compounds that produce minimal side effects and are suitable for long-term use. These compounds include those occurring in nature or already produced by the human body (such as neurotransmitters), and their synthetic analogs. We already regularly consume some of these chemicals: B vitamins, caffeine, and L-theanine, in our daily diets.

A fundamental aspect of human evolution has been the drive to augment our capabilities. The neocortex is the neural seat of abstract and higher order cognitive processes. As it grew, so did our ability to create. The invention of tools and weapons, writing, the steam engine, and the computer have exponentially increased our capacity to influence and understand the world around us. These advances are being driven by improved higher-order cognitive processing.1Fascinatingly, the practice of modulating our biology through naturally occurring flora predated all of the above discoveries. Indeed, Sumerian clay slabs as old as 5000 BC detail medicinal recipes which include over 250 plants2. The enhancement of human cognition through natural compounds followed, as people discovered plants containing caffeine, theanine, and other cognition-enhancing, or nootropic, agents.

There is an ancient precedent to humans using natural compounds to elevate cognitive performance. Incan warriors in the 15th century would ingest coca leaves (the basis for cocaine) before battle. Ethiopian hunters in the 10th century developed coffee bean paste to improve hunting stamina. Modern athletes ubiquitously consume protein powders and hormones to enhance their training, recovery, and performance. The most widely consumed psychoactive compound today is caffeine. Millions of people use coffee and tea to be more alert and focused.

The term nootropic is simply a descriptor, and this descriptor spans across all legal classifications of compounds. Broadly speaking, there are four main classifications:

Nootrobox stacks are strictly derived from the first category - compounds that are GRAS and approved for human consumption as dietary supplements.

The mechanisms by which nootropic compounds influence our cognition and neurophysiology are as diverse as those of prescription drugs. We present below our in-progress work, detailing the mechanisms, effects, and history of various nootropic compounds. Check in for updates and additions.

Nootropics | HVMN Biohacker Guide

What is a Nootropic – What are nootropics?

The word nootropic is derived from the greek words noos, meaning mind, and trope, meaning turning. In essence, nootropic perform one function: they turn your mind to boost your cognitive abilities and make your mental state better in some way, shape, or form.

Different groups classify different drugs as nootropics, but for the most part, everyone agrees that nootropics have two defining characteristics:

Keep in mind that nootropics are not vitamins or minerals. Usually, theyre synthetic chemicals produced in laboratories. Theyre not essential to your bodys functions. Theyre add-ons in that you use them and you feel better, but if you dont, its not like your body is lacking anything otherwise required. We do advocate getting the proper amount of essential nutrients, and minerals as a starting point to improved cognitive health. Well talk about generally optimizing brain health (your cognitive baseline) through sleep, diet, and exercise a later post.

Were being relatively vague here because there is a wide spectrum of nootropics available today. And they all claim to do different things for you. Its up to you to pick the right nootropic for what you want to accomplish. Later posts will cover the different types of nootropics, as well as specific nootropics to use in certain scenarios for studying, for sharpness, for recovery after partying, etc.

After understanding what a nootropic is, the next question that begs to be asked is, How do they work?

Every nootropic affects your body in a different way. Its important to note the distinction between results and commonly referred to as working mechanisms. One thing that we also want to note is that nootropics are a very subjective experience, and although one person may have great results with a particular nootropic, another person may have no result when using that same nootropic.

If the working mechanism for a drug is known, we know exactly how it affects your body. As in, if you ingest drug A, it affects receptors X, Y, and Z. This modification to receptors X, Y, and Z produces effects B, C, and D.

If the working mechanism for a drug isnt known, then we only know A, B, C, and D in the above example. For most nootropics, there is speculation behind the working mechanisms, but there has not been any conclusive evidence of these claims. As such, the working mechanisms being discussed are theories, not fact.

Dont let this turn you off of nootropics as a safe way to improve your mental function. The human body is incredibly complex, and we havent even begun to understand how all the pieces of the puzzle fit together. We dont even know the working mechanisms for some of the most popular drugs sold worldwide.

Take acetaminophen (the active ingredient in Tylenol) as an example. There have been tens of thousands of studies conducted with this drug, and after studying human reactions to it over, and over, and over again, weve come to these three conclusions:

Youd think that after tens of thousands of studies, a working mechanism would have been found, right? Unfortunately not the working mechanism for acetaminophen isnt known, and it doesnt look like well know exactly how it works anytime soon.

Take this example and apply it to nootropics. The working mechanisms usually arent known, but after observing empirical evidence over, and over, and over again, we can come to some pretty consistent conclusions about them.

Now, we know what youre thinking; If these drugs claim to enhance your cognitive abilities but the working mechanisms arent 100% known, are they legal?

The answer is both yes and no.

Yes: most nootropics are perfectly legal to possess. This means that if a police officer were to see you taking one and stop you, hed likely be suspicious (nootropics often come in the form of white powder), but if he were to conduct a field test on it, you would not be arrested or issued a ticket. Your package wont be taken if inspected by customs, etc.

No: like dietary supplements, most nootropics arent approved by the FDA. All countries vary on the legality of nootropics. In Russia, most are legal, and many are prescription medicines. We suggest that you research the laws of your country regarding possession of a particular nootropic before you order. Those are just two examples. Always do your research on your specific countrys laws before purchasing any nootropic supplements.

The cool (and sometimes off-putting) thing about nootropics is that everyone reacts differently to each one. This is pretty standard with drugs in general if we take marijuana as an example, it relaxes some people, whereas it makes other anxious and paranoid. Its your personal reaction.

In general, the effects of nootropics are fairly mild. Theyre not meant to be stimulants like adderall, ritalin, vyvanse, or concerta. Instead, they aim to take your base level of cognitive performance and bring it up. Go from being able to give 100% when not taking nootropics, to being able to give 105% or 110% when you are. If you focus in on how the nootropic is affecting you, youll be able to tell, but with the vast majority of nootropics, you wont feel over-stimulated or anything of that nature, sometime the effects are rather subtle. One thing that we suggest is tracking the efficacy of the nootropics you take to really determine the value you are getting from nootropics; this is covered later.

Also, you should expect no comedown and no come up. Nootropics work in the background. When you dose, you wont feel a rush (although some do report a tingly feeling), and when the nootropic starts to wear off, you wont feel like youre crashing. Instead, youll slowly climb to where your cognitive abilities are enhanced, and then gradually ease off of that as the chemical is depleted until youre at your normal baseline mental state.

Every nootropic out there can be categorized into a certain subset of nootropics. Here are the main ones below all popular nootropics will fall into one of these categories. Well talk about some more specific nootropics later. If youd like to skip ahead to the best nootropics for beginners, click here

Racetams (One our of favorites)

All racetams (about 20 in total, depending on who you ask) are derived from the king: piracetam. After being synthesized in the early 1970s, piracetam quickly took its place at the vanguard of the nootropic movement if you ask someone to name a nootropic, piracetam will always be the first answer.

The formula for piracetam is C6H10N2O2, and most of its derivatives such a aniracetam, oxiracetam, and pramiracetam have certain elements added or removed from that base structure. Good ol piracetam provides a wide range of cognitive enhancements including improved memory, improved verbal articulation, improved long and short term memory, etc.

More often than not, a racetam is the base of any nootropic stack. Users often add other nootropics to enhance the effects of a racetam.

If youre diving into nootropics and want the surefire bet, choose piracetam. But if you have certain needs maybe you want more energy than piracetam, or you need a creative boost then its worth checking out its derivatives. Despite their formulaic similarities, users report substantially different effects when taking them.

Choline (usually paired with racetams)

Choline isnt usually used by itself in the nootropic landscape, but its a very common addition to any nootropic combination (stack). There are two reasons for this, choline itself gives you additional cognitive enhancements, and adding choline is theorized to boost the effects of any racetam that increases acetylcholine uptake. Choline was once classified as vitamin B4 and has since been reclassified as an essential nutrient and is metabolized by the body in acetylcholine.

Before going further I want to note that acetylcholine is an important neurotransmitter that is thought to be responsible for decision making and certain types of learning. Many nootropics have some effect on the way the body processes or interacts with acetylcholine and those effects generally have cognitive benefits when utilized responsibly.

To put it simply, adding in a choline source means that you have an increased amount of acetylcholine available in your body. Having plenty of acetylcholine is said to have cognitive enhancing benefits all by itself, but theyre usually amplified when you have another nootropic in the mix.

Also, there have been studies that suggest piracetam (and most other racetams) deplets the acetylcholine you havein your brain. If your body doesnot have enough acetylcholine, the end result is that youll often end up with headaches. The same works the other way, which is another reason why almost no one adds in a choline source without adding in a nootropic, as having too much acetylcholine (or anything else for that matter) is generally not a good thing. They balance each other out perfectly to give you cognitive enhancementand prevent you from getting headaches; its a symbiotic relationship that requires balancing.

Youll notice that there are two terms mentioned here acetylcholine and choline sources. Choline sources are the actual supplements you take, and once ingested, they increase your acetylcholine levels.Every choline source will produce a different amount of acetylcholine. Alpha GPC is considered to be the most potent with highest bioavailability. A rudimentary search will put you on the right track see what others users have paired with their particular nootropics to balance acetylcholine levels correctly. For more information on choline, check out our beginners guide to choline.

The Natural Ones

Natural nootropics are no different from what youd referred to as natural herbs or natural remedies; they are naturally-occurring elements (from plants) that when ingested, provide cognitive enhancing effects.

The effects of natural nootropics vary greatly, and by and large, users have vastly different experiences with each and every one. Some claim theyre straight placebo, whereas others think that they can be even more potent than their human-made counterparts. However, the general consensus is that theyre less potent than synthetic nootropics are.

This shouldnt turn you off to them as a whole. Although less potent, some natural nootropics provide benefits in some way, shape, or form that synthetic ones cant match. Generall speaking, because natural nootropics are (by definition) from nature, they are often available at a cheaper price than synthetic nootropics are. No laboratories, purity tests, etc. are needed.

Bacopi Monneri is one of the most prevalent natural nootropics. It acts as a memory and anxiety aid, but effects usually take 6-8 weeks to kick in this is a great example of natural nootropics being less potent than a synthetic memory or anxiety aid that might take effect within just a couple of days, or even immediately. Its also a great example of how one can work in a way that its synthetic counterpart cant while anti-anxiety nootropics are usually borderline sedative, users report that Bacopi Monneri works in the background so that you dont feel like youre under the influence.

Other popular natural nootropics are Huperzine-A, and Gingko Biloba. If youre interested in nootropics but arent a fan of the ones produced in laboratories, these three are great jumping-off points.

Smart Drugs

Smart drugs are where the border between nootropic and drug is tested; some consider smart drugs to be nootropics, whereas others think that they should be heavily regulated just as prescription medications are.

Modafinil is the best example of a smart drug. Its prescribed in some countries, banned in some, and completely legal in others. It promises a full-blown energy increase similar to adderall, but without the euphoria or other side effects.

Many people think that smart drugs like modafinil arent nootropics because of how they affect you. If you take a standard nootropic like piracetam for a month straight and then abruptly stop, you might notice the nootropic not being present, but you wont have any real side effects. On the other hand, dosing a smart drug like modafinil on a consistent basis and then suddenly stopping might lead to insomnia, lack of focus, etc.

Were not saying that smart drugs are bad, necessarily. Were just saying that you shouldnt expect a subtle effect like other nootropics give you. When you take one, youll easily notice the effects, and when you come off of it, youll easily notice that you arent on it.

Vitamin B & Vitamin B Derivatives

B vitamins are unique in how they affect us. One of the most popular energy drinks, 5 Hour Energy, has vitamin B6 as its main ingredient (albeit 10,000x the RDA) because of the energy boost that it gives to us.

Naturally, with such effects, B vitamins are being explored as nootropics. Its important to note that vitamin B derivatives arent the same thing as B vitamins;theyve been modified in some way to become something other than the naturally-occurring vitamin.As of 2015, vitamin B derivatives are relatively new. Sulbutiamine is a derivative of vitamin B1 that was originally developed by the Japanese to combat fatigue, and it has the largest user base out of all of them. Picamillion is also a B derived nootropic as it combines niacin (B3) with GABA . More research is needed to conclude anything about B vitamins, but if youve had success from taking a B-complex or an energy drink like 5 Hour Energy, theyre worth exploring.

Ampakides

Ampakides are generally seen as piracetam was in the 80s and 90s interesting, but not researched a whole lot. Actually, out of all of the different types of nootropics, ampakides have the least research done on them.

They appear to work by antagonizing the AMPA and NDMA receptors in your body; this in turn leads to an uptick in glutamate available for your brain to use. Glutamate is said to increase memory span and focus abilities. But again, there hasnt been a whole lot of research done on ampakides or how they will affect you in the long-term.Only use ampakides if youre an explorer and willing to ingest something that hasnt been fully studied.

Peptides

Peptides are interesting in that they operate similarly to racetams, but arent the same thing. There arent a whole lot on the market today aside from noopept.

Noopept has quickly earned a reputation for being 1,000x more potent than piracetam while having similar effects. This means that the dosage is a lot smaller whereas you need 1.6g to 4.8g of piracetam per day, you only need 10mg to 40mg of noopept per day.

Although not as popular as racetams, peptides are worth exploring. Many users report similar effects as racetams, but not identical. Some like peptides more, whereas others stick with racetams. If you dont like what you feel from a certain racetam, its worth exploring peptides.

Blends

Many companies have jumped on the nootropic bandwagon and created nootropic blends. These blends are just a bunch of nootropics combined into a single pill, which is similar to stacking nootropics all on your own just easier.

Its important to take a look at the ingredients of each blend that youre considering. Sometimes, there will be ingredients that arent nootropics, and other times, there will be a blend of ingredients that you could easily concoct yourself for a fraction of the price. Often times they dont contain proper dosages of the ingredients to make them worthwhile.

The most popular nootropic blend is Alpha Brain from Onnit; you can check out our Alpha Brain full review and analysis here. By and large, people see success with this blend, but a lot of marketing is put into it its hard to get unbiased information when you look online. Wed recommend starting with pure nootropics first, and if you find one that you like, possibly getting a blend that has your choice nootropic as the #1 ingredient. If theres something we missed, please let us know so that we can bring our customers the most relevant information possible.

NeuroFit is another nootropic that goes heavy on the vitamins and minerals, but is secretive about the amounts of the actual nootropic ingredients in its formulation. With so many ingredients, it seems unlikely that the active ingredients are present in high concentrations.

Nootropics are supplements that are designed to boost cognitive functionthat is, enhance your brains ability to learn, remember, and solve problems.

Though they are extremely popular among students, nootropics have a much broader appeal. Just about anybody in a complex job wants the ability to work faster and more effectively, and people who are getting older like the appeal of staving off brain fog and some of the cognitive decline that comes along with aging.

When a supplement claims to impact cognitive function, its a fairly easy claim to test.

Unlike other supplements that claim to boost well-being or promote a healthy immune system, testing cognitive function is straightforward: you get a group of subjects, give them the supplement in question or a placebo, then subject them to a battery of psychometric tests to assess their cognitive function.

There are a variety of types of these kinds of tests, and different supplements seem to affect different aspects of cognitive function. Some seem to boost memory, while others influence verbal abilities or help reduce mental fatigue (the diminishing of cognitive performance after long, challenging efforts).

A good case study in how testing nootropics work can be observed in the 2016 study that validated the effects of Alpha Brain (2).

Researchers split a group of volunteers into two groups, one of which was given Alpha Brain, and the other of which was given a placebo supplement. Both groups were tested for their cognitive abilities at the outset of the study, then took their assigned supplement for six weeks before being tested again.

The psychometric battery of tests used in the study included visual, spatial, logical, and verbal reasoning and memory. The results showed no improvement in most metrics, but a statistically significant increase in verbal memory.

Other supplements have been studied on an individual level to identify potential nootropic benefits. As you might guess, the most popular ingredients among the top-ranked nootropic supplements are also among the best-studied and most effective.

Bacopa monnieri, for example, is an herbal extract thats been demonstrated to have specific cognitive enhancing effects. A 2001 study in the scientific journal Psychopharmacology conducted a similar protocol to the Alpha Brain studya group of healthy adult subjects were given a 300 mg dose of bacopa monnieri extract or a placebo for twelve weeks, and were subjected to a battery of cognitive tests before and after the supplementation period (3).

In this case, the researchers found that the bacopa supplement increased the speed of visual information processing, learning rate, and memory consolidation.

Ginkgo biloba and vinpocetine looks to be an effective supplement when it comes to speeding up your short-term working memory.

A study published in the journal Human Psychopharmacology used a similar placebo-controlled experiment to study the effects of a combination of ginkgo biloba and vinpocetine on cognitive function, and found that the supplement combination increased the speed at which your working memory functions after being taken for two weeks (4).

When looking at nootropic supplements, youll have to think specifically about what kind of cognitive enhancement you are looking for.

When working on a major writing project, or attempting to work through a lot of reading material, taking something like Alpha Brain that increases verbal memory is could be very helpful.

On the other hand, something that improves visual information processing and learning rate, like bacopa monnieri extract, would likely speed your ability to learn math flash cards or process on-screen visual information.

If you were doing data entry, you might want something to improve short-term working memory, like ginkgo biloba and vinpocetine.

Its clear that taking the time to analyze the specific cognitive demands of the task in question will help immensely when you are deciding what the ideal nootropic supplement is for you.

Other nootropic supplements were studied initially to help with cognitive decline and dementia in the elderly, but have been hypothesized to be effective as well in healthy people.

One example of this is the herbal supplement huperzine-A. Early research found that it had a strong anti-dementia effect. A 1999 experiment described using a huperzine-A supplement to reverse natural dementia in elderly monkeys, as well as reversing chemically-induced cognitive decline in young monkeys (5).

Research into whether it can be used to actually boost cognitive performance in healthy humans is still lacking, but this hasnt stopped people from betting that it will.

An entirely different strategy in nootropics is simply providing your brain with extra building blocks to use in the process of synthesizing neurotransmitters, which are chemicals your brain uses to think. Many nootropics simply provide high doses of the amino acids that are associated with cognitive function.

These are less well-studied, perhaps because simply keeping your brains amino acid reserved topped off isnt as exciting as artificially enhancing its performance, but its nevertheless a strategically sound approach.

Since nootropic supplements are so new, their side effect profile is not well-studied. So far, there have been no major adverse side effects reported that are associated with the ingredients used in the best and most popular nootropic supplements.

In this regard they appear to have a safer safety profile than other categories of multi-ingredient supplements, like weight loss supplements.

The one caveat to this applies to nootropic supplements that contain caffeine. While caffeine is one of the best-studied and most effective cognitive enhancement supplements (as every coffee addict knows), it can cause side effects like jitters and nausea in people who are sensitive to it.

Further, taking it at night is a bad idea, thanks to caffeines ability to act as a stimulantunless, of course, you are trying to stay up all night. Theres nothing wrong with caffeine in a nootropic supplement, but make sure you know how many milligrams each serving contains.

Only a small number of nootropics have established effective doses, and these are mostly derived from the dosages chosen in scientific studies that examined the supplement in question.

Bacopa monnieri, for example, appears to be effective at doses of 300 mg, and ginkgo biloba extract can be effective at doses as low as 40 mg.

Vinpocetine seems to require doses of 30 to 60 mg, but this comes from scientific literature using it to study cognitive decline and dementia in the elderly, so its not clear if boosting brain function in healthy people can be accomplished with a lower dose.

DMAEs studied dosage range is typically about 100 mg, but this seems to come from studies looking at its use to induce lucid dreaming!

Clearly, more work is needed to establish optimal doses for nootropic supplements, but looking for dosages close to these guidelines is at least a good place to start.

Nootropics are a new field of supplementation, but there is fairly strong evidence emerging that a number of different supplements can positively affect your cognitive functioning.

Each seems to serve a slightly different purpose, so think about the cognitive demands in your life before you choose a nootropic supplement. Once you know the kinds of problems you want to solve, make sure your supplement of choice has dosages of the major nootropic compounds you want that are at least close to the range studied in the scientific literature.

When done with care, nootropics appear to be a safe and effective way to increase your brain power and help you work faster, smarter, and more effectively.

Product Claims

NeuroFuse came in a close second. It had the right idea to provide the wide range of ingredients it did in their formula. They included some key ingredients including Bacopa Monnieri, Huperzine A, Vinpocetine and also included a good Vitamin B blend. We did note that they include caffeine, but it is unclear from which source this is from.

We did note a significant warning with this product, namely that the caffeine it contains may cause a negative impact, mainly that some users may experience the jitters. Their dosage suggests that one can take up to 6 pills a day, which we felt was too many. These issues made us a little wary of the product, even though they seem to know the right ingredients to include.

We felt that NeuroFuse was pretty much on par with other similar products. We were happy to see that this supplier offers a money-back guarantee. However, we didn't really like the 14-day trial offer they promote. On the surface it seems good, however, our experience on these matters suggests that if consumers are not happy with the product, cancelling subscriptions can be a nightmare. We much prefer a simple clear money-back guarantee, it's safer for consumers.

NeuroFuse was almost there with a top quality product but we felt that there were several key elements missing. It does contain a lot of the top natural ingredients for cognitive energy enhancement. However, the fact that their money-back guarantee is not apparent and that they are baiting customers in using a 14-day free trial offer, made us slightly wary. If they addressed these issues, we felt that this could have been a winner!

High Seas Fleet – Wikipedia

Naval battle during WWI

The High Seas Fleet (Hochseeflotte) was the battle fleet of the German Imperial Navy and saw action during the First World War. The formation was created in February 1907, when the Home Fleet (Heimatflotte) was renamed as the High Seas Fleet. Admiral Alfred von Tirpitz was the architect of the fleet; he envisioned a force powerful enough to challenge the Royal Navy's predominance. Kaiser Wilhelm II, the German Emperor, championed the fleet as the instrument by which he would seize overseas possessions and make Germany a global power. By concentrating a powerful battle fleet in the North Sea while the Royal Navy was required to disperse its forces around the British Empire, Tirpitz believed Germany could achieve a balance of force that could seriously damage British naval hegemony. This was the heart of Tirpitz's "Risk Theory," which held that Britain would not challenge Germany if the latter's fleet posed such a significant threat to its own.

The primary component of the Fleet was its battleships, typically organized in eight-ship squadrons, though it also contained various other formations, including the I Scouting Group. At its creation in 1907, the High Seas Fleet consisted of two squadrons of battleships, and by 1914, a third squadron had been added. The dreadnought revolution in 1906 greatly affected the composition of the fleet; the twenty-four pre-dreadnoughts in the fleet were rendered obsolete and required replacement. Enough dreadnoughts for two full squadrons were completed by the outbreak of war in mid 1914; the eight most modern pre-dreadnoughts were used to constitute a third squadron. Two additional squadrons of older vessels were mobilized at the onset of hostilities, though by the end of the conflict, these formations were disbanded.

The fleet conducted a series of sorties into the North Sea during the war designed to lure out an isolated portion of the numerically superior British Grand Fleet. These operations frequently used the fast battlecruisers of the I Scouting Group to raid the British coast as the bait for the Royal Navy. These operations culminated in the Battle of Jutland, on 31 May1 June 1916, where the High Seas Fleet confronted the whole of the Grand Fleet. The battle was inconclusive, but the British won strategically, as it convinced Admiral Reinhard Scheer, the German fleet commander, that even a highly favorable outcome to a fleet action would not secure German victory in the war. Scheer and other leading admirals therefore advised the Kaiser to order a resumption of the unrestricted submarine warfare campaign. The primary responsibility of the High Seas Fleet in 1917 and 1918 was to secure the German naval bases in the North Sea for U-boat operations. Nevertheless, the fleet continued to conduct sorties into the North Sea and detached units for special operations in the Baltic Sea against the Russian Baltic Fleet. Following the German defeat in November 1918, the Allies interned the bulk of the High Seas Fleet in Scapa Flow, where it was ultimately scuttled by its crews in June 1919, days before the belligerents signed the Treaty of Versailles.

In 1898, Admiral Alfred von Tirpitz became the State Secretary for the Imperial Navy Office (ReichsmarineamtRMA);[1] Tirpitz was an ardent supporter of naval expansion. During a speech in support of the First Naval Law on 6 December 1897, Tirpitz stated that the navy was "a question of survival" for Germany.[2] He also viewed Great Britain, with its powerful Royal Navy, as the primary threat to Germany. In a discussion with the Kaiser during his first month in his post as State Secretary, he stated that "for Germany the most dangerous naval enemy at present is England."[3] Tirpitz theorized that an attacking fleet would require a 33percent advantage in strength to achieve victory, and so decided that a 2:3 ratio would be required for the German navy. For a final total of 60 German battleships, Britain would be required to build 90 to meet the 2:3 ratio envisioned by Tirpitz.[3]

The Royal Navy had heretofore adhered to the so-called "two-power standard," first formulated in the Naval Defence Act of 1889, which required a larger fleet than those of the next two largest naval powers combined.[4] The crux of Tirpitz's "risk theory" was that by building a fleet to the 2:3 ratio, Germany would be strong enough that even in the event of a British naval victory, the Royal Navy would incur damage so serious as to allow the third-ranked naval power to rise to preeminence. Implicit in Tirpitz's theory was the assumption that the British would adopt an offensive strategy that would allow the Germans to use mines and submarines to even the numerical odds before fighting a decisive battle between Heligoland and the Thames. Tirpitz in fact believed Germany would emerge victorious from a naval struggle with Britain, as he believed Germany to possess superior ships manned by better-trained crews, more effective tactics, and led by more capable officers.[3]

In his first program, Tirpitz envisioned a fleet of nineteen battleships, divided into two eight-ship squadrons, one ship as a flagship, and two in reserve. The squadrons were further divided into four-ship divisions. This would be supported by the eight Siegfried- and Odin classes of coastal defense ships, six large and eighteen small cruisers, and twelve divisions of torpedo boats, all assigned to the Home Fleet (Heimatflotte).[5] This fleet was secured by the First Naval Law, which passed in the Reichstag on 28 March 1898.[6] Construction of the fleet was to be completed by 1 April 1904. Rising international tensions, particularly as a result of the outbreak of the Boer War in South Africa and the Boxer Rebellion in China, allowed Tirpitz to push through an expanded fleet plan in 1900. The Second Naval Law was passed on 14 June 1900; it doubled the size of the fleet to 38 battleships and 20 large and 38 small cruisers. Tirpitz planned an even larger fleet. As early as September 1899, he had informed the Kaiser that he sought at least 45 battleships, and potentially might secure a third double-squadron, for a total strength of 48 battleships.[7]

During the initial period of German naval expansion, Britain did not feel particularly threatened.[6] The Lords of the Admiralty felt the implications of the Second Naval Law were not a significantly more dangerous threat than the fleet set by the First Naval Law; they believed it was more important to focus on the practical situation rather than speculation on future programs that might easily be reduced or cut entirely. Segments of the British public, however, quickly seized on the perceived threat posed by the German construction programs.[8] Despite their dismissive reaction, the Admiralty resolved to surpass German battleship construction. Admiral John Fisher, who became the First Sea Lord and head of the Admiralty in 1904, introduced sweeping reforms in large part to counter the growing threat posed by the expanding German fleet. Training programs were modernized, old and obsolete vessels were discarded, and the scattered squadrons of battleships were consolidated into four main fleets, three of which were based in Europe. Britain also made a series of diplomatic arrangements, including an alliance with Japan that allowed a greater concentration of British battleships in the North Sea.[9]

Fisher's reforms caused serious problems for Tirpitz's plans; he counted on a dispersal of British naval forces early in a conflict that would allow Germany's smaller but more concentrated fleet to achieve a local superiority. Tirpitz could also no longer depend on the higher level of training in both the German officer corps and the enlisted ranks, nor the superiority of the more modern and homogenized German squadrons over the heterogeneous British fleet. In 1904, Britain signed the Entente cordiale with France, Britain's primary naval rival. The destruction of two Russian fleets during the Russo-Japanese War in 1905 further strengthened Britain's position, as it removed the second of her two traditional naval rivals.[10] These developments allowed Britain to discard the "two power standard" and focus solely on out-building Germany. In October 1906, Admiral Fisher stated "our only probable enemy is Germany. Germany keeps her whole Fleet always concentrated within a few hours of England. We must therefore keep a Fleet twice as powerful concentrated within a few hours of Germany."[11]

The most damaging blow to Tirpitz's plan came with the launch of HMSDreadnought in February 1906. The new battleship, armed with a main battery of ten 12-inch (30cm) guns, was considerably more powerful than any battleship afloat. Ships capable of battle with Dreadnought would need to be significantly larger than the old pre-dreadnoughts, which increased their cost and necessitated expensive dredging of canals and harbors to accommodate them. The German naval budget was already stretched thin; without new funding, Tirpitz would have to abandon his challenge to Britain.[12] As a result, Tirpitz went before the Reichstag in May 1906 with a request for additional funding. The First Amendment to the Second Naval Law was passed on 19 May and appropriated funding for the new battleships, as well as for the dredging required by their increased size.[6]

The Reichstag passed a second amendment to the Naval Law in March 1908 to provide an additional billion marks to cope with the growing cost of the latest battleships. The law also reduced the service life of all battleships from 25 to 20 years, which allowed Tirpitz to push for the replacement of older vessels earlier. A third and final amendment was passed in May 1912 represented a compromise between Tirpitz and moderates in parliament. The amendment authorized three new battleships and two light cruisers. The amendment called for the High Seas Fleet to be equipped with three squadrons of eight battleships each, one squadron of eight battlecruisers, and eighteen light cruisers. Two 8-ship squadrons would be placed in reserve, along with two armored and twelve light cruisers.[13] By the outbreak of war in August 1914, only one eight-ship squadron of dreadnoughtsthe I Battle Squadronhad been assembled with the Nassau and Helgoland-class battleships. The second squadron of dreadnoughtsthe III Battle Squadronwhich included four of the Kaiser-class battleships, was only completed when the four Knig-class battleships entered service by early 1915.[14] As a result, the third squadronthe II Battle Squadronremained composed of pre-dreadnoughts through 1916.[15]

Before the 1912 naval law was passed, Britain and Germany attempted to reach a compromise with the Haldane Mission, led by the British War Minister Richard Haldane. The arms reduction mission ended in failure, however, and the 1912 law was announced shortly thereafter. The Germans were aware at as early as 1911, the Royal Navy had abandoned the idea of a decisive battle with the German fleet, in favor of a distant blockade at the entrances to the North Sea, which the British could easily control due to their geographical position. There emerged the distinct possibility that the German fleet would be unable to force a battle on its own terms, which would render it militarily useless. When the war came in 1914, the British did in fact adopt this strategy. Coupled with the restrictive orders of the Kaiser, who preferred to keep the fleet intact to be used as a bargaining chip in the peace settlements, the ability of the High Seas Fleet to affect the military situation was markedly reduced.[16]

The German Navy's pre-war planning held that the British would be compelled to mount either a direct attack on the German coast to defeat the High Seas Fleet, or to put in place a close blockade. Either course of action would permit the Germans to whittle away at the numerical superiority of the Grand Fleet with submarines and torpedo boats. Once a rough equality of forces could be achieved, the High Seas Fleet would be able to attack and destroy the British fleet.[17] Implicit in Tirpitz's strategy was the assumption that German vessels were better-designed, had better-trained crews, and would be employed with superior tactics. In addition, Tirpitz assumed that Britain would not be able to concentrate its fleet in the North Sea, owing to the demands of its global empire. At the start of a conflict between the two powers, the Germans would therefore be able to attack the Royal Navy with local superiority.[18]

The British, however, did not accommodate Tirpitz's projections; from his appointment as the First Sea Lord in 1904, Fisher began a major reorganization of the Royal Navy. He concentrated British battleship strength in home waters, launched the Dreadnought revolution, and introduced rigorous training for the fleet personnel.[19] In 1912, the British concluded a joint defense agreement with France that allowed the British to concentrate in the North Sea while the French defended the Mediterranean.[20] Worse still, the British began developing the strategy of the distant blockade of Germany starting in 1904;[21] this removed the ability of German light craft to reduce Britain's superiority in numbers and essentially invalidated German naval planning before the start of World War I.[22]

The primary base for the High Seas Fleet in the North Sea was Wilhelmshaven on the western side of the Jade Bight; the port of Cuxhaven, located on the mouth of the Elbe, was also a major base in the North Sea. The island of Heligoland provided a fortified forward position in the German Bight.[23] Kiel was the most important base in the Baltic, which supported the forward bases at Pillau and Danzig.[24] The Kaiser Wilhelm Canal through Schleswig-Holstein connected the Baltic and North Seas and allowed the German Navy to quickly shift naval forces between the two seas.[25] In peacetime, all ships on active duty in the High Seas Fleet were stationed in Wilhelmshaven, Kiel, or Danzig.[26] Germany possessed only one major overseas base, at Kiautschou in China,[27] where the East Asia Squadron was stationed.[28]

Steam ships of the period, which burned coal to fire their boilers, were naturally tied to coaling stations in friendly ports. The German Navy lacked sufficient overseas bases for sustained operations, even for single ships operating as commerce raiders.[29] The Navy experimented with a device to transfer coal from colliers to warships while underway in 1907, though the practice was not put into general use.[30] Nevertheless, German capital ships had a cruising range of at least 4,000nmi (7,400km; 4,600mi),[31] more than enough to operate in the Atlantic Ocean.[Note 1]

In 1897, the year Tirpitz came to his position as State Secretary of the Navy Office, the Imperial Navy consisted of a total of around 26,000 officers, petty officers, and enlisted men of various ranks, branches, and positions. By the outbreak of war in 1914, this had increased significantly to about 80,000 officers, petty officers, and men.[35] Capital ships were typically commanded by a Kapitn zur See (Captain at Sea) or Korvettenkapitn (corvette captain).[26] Each of these ships typically had a total crew in excess of 1,000 officers and men;[31] the light cruisers that screened for the fleet had crew sizes between 300 and 550.[36] The fleet torpedo boats had crews of about 80 to 100 officers and men, though some later classes approached 200.[37]

In early 1907, enough battleshipsof the Braunschweig and Deutschland classeshad been constructed to allow for the creation of a second full squadron.[38] On 16 February 1907,[39] Kaiser Wilhelm renamed the Home Fleet the High Seas Fleet. Admiral Prince Heinrich of Prussia, Wilhelm II's brother, became the first commander of the High Seas Fleet; his flagship was SMSDeutschland.[38] While on a peacetime footing, the Fleet conducted a routine pattern of training exercises, with individual ships, with squadrons, and with the combined fleet, throughout the year. The entire fleet conducted several cruises into the Atlantic Ocean and the Baltic Sea.[40] Prince Henry was replaced in late 1909 by Vice Admiral Henning von Holtzendorff, who served until April 1913. Vice Admiral Friedrich von Ingenohl, who would command the High Seas Fleet in the first months of World War I, took command following the departure of Vice Admiral von Holtzendorff.[41] SMSFriedrich der Grosse replaced Deutschland as the fleet flagship on 2 March 1913.[42]

Despite the rising international tensions following the assassination of Archduke Franz Ferdinand on 28 June, the High Seas Fleet began its summer cruise to Norway on 13 July. During the last peacetime cruise of the Imperial Navy, the fleet conducted drills off Skagen before proceeding to the Norwegian fjords on 25 July. The following day the fleet began to steam back to Germany, as a result of Austria-Hungary's ultimatum to Serbia. On the 27th, the entire fleet assembled off Cape Skudenes before returning to port, where the ships remained at a heightened state of readiness.[42] War between Austria-Hungary and Serbia broke out the following day, and in the span of a week all of the major European powers had joined the conflict.[43]

The High Seas Fleet conducted a number of sweeps and advances into the North Sea. The first occurred on 23 November 1914, though no British forces were encountered. Admiral von Ingenohl, the commander of the High Seas Fleet, adopted a strategy in which the battlecruisers of Rear Admiral Franz von Hipper's I Scouting Group raided British coastal towns to lure out portions of the Grand Fleet where they could be destroyed by the High Seas Fleet.[44] The raid on Scarborough, Hartlepool and Whitby on 1516 December 1914 was the first such operation.[45] On the evening of 15 December, the German battle fleet of some twelve dreadnoughts and eight pre-dreadnoughts came to within 10nmi (19km; 12mi) of an isolated squadron of six British battleships. However, skirmishes between the rival destroyer screens in the darkness convinced von Ingenohl that he was faced with the entire Grand Fleet. Under orders from the Kaiser to avoid risking the fleet unnecessarily, von Ingenohl broke off the engagement and turned the fleet back toward Germany.[46]

Following the loss of SMSBlcher at the Battle of Dogger Bank in January 1915, the Kaiser removed Admiral von Ingenohl from his post on 2 February. Admiral Hugo von Pohl replaced him as commander of the fleet.[47] Admiral von Pohl conducted a series of fleet advances in 1915; in the first one on 2930 March, the fleet steamed out to the north of Terschelling and returned without incident. Another followed on 1718 April, where the fleet covered a mining operation by the II Scouting Group. Three days later, on 2122 April, the High Seas Fleet advanced towards the Dogger Bank, though again failed to meet any British forces.[48] Another sortie followed on 2930 May, during which the fleet advanced as far as Schiermonnikoog before being forced to turn back by inclement weather. On 10 August, the fleet steamed to the north of Heligoland to cover the return of the auxiliary cruiser Meteor. A month later, on 1112 September, the fleet covered another mine-laying operation off the Swarte Bank. The last operation of the year, conducted on 2324 October, was an advance without result in the direction of Horns Reef.[48]

Vice Admiral Reinhard Scheer became Commander in chief of the High Seas Fleet on 18 January 1916 when Admiral von Pohl became too ill to continue in that post.[49] Scheer favored a much more aggressive policy than that of his predecessor, and advocated greater usage of U-boats and zeppelins in coordinated attacks on the Grand Fleet; Scheer received approval from the Kaiser in February 1916 to carry out his intentions.[50] Scheer ordered the fleet on sweeps of the North Sea on 26 March, 23 April, and 2122 April. The battlecruisers conducted another raid on the English coast on 2425 April, during which the fleet provided distant support.[51] Scheer planned another raid for mid-May, but the battlecruiser Seydlitz had struck a mine during the previous raid and the repair work forced the operation to be pushed back until the end of the month.[52]

Admiral Scheer's fleet, composed of 16 dreadnoughts, six pre-dreadnoughts, six light cruisers, and 31 torpedo boats departed the Jade early on the morning of 31 May. The fleet sailed in concert with Hipper's five battlecruisers and supporting cruisers and torpedo boats.[53] The Royal Navy's Room 40 had intercepted and decrypted German radio traffic containing plans of the operation. The Admiralty ordered the Grand Fleet, totaling some 28 dreadnoughts and 9 battlecruisers, to sortie the night before in order to cut off and destroy the High Seas Fleet.[54]

At 16:00 UTC, the two battlecruiser forces encountered each other and began a running gun fight south, back towards Scheer's battle fleet.[55] Upon reaching the High Seas Fleet, Vice Admiral David Beatty's battlecruisers turned back to the north to lure the Germans towards the rapidly approaching Grand Fleet, under the command of Admiral John Jellicoe.[56] During the run to the north, Scheer's leading ships engaged the Queen Elizabeth-class battleships of the 5th Battle Squadron.[57] By 18:30, the Grand Fleet had arrived on the scene, and was deployed into a position that would cross Scheer's "T" from the northeast. To extricate his fleet from this precarious position, Scheer ordered a 16-point turn to the south-west.[58] At 18:55, Scheer decided to conduct another 16-point turn to launch an attack on the British fleet.[59]

This maneuver again put Scheer in a dangerous position; Jellicoe had turned his fleet south and again crossed Scheer's "T."[60] A third 16-point turn followed; Hipper's mauled battlecruisers charged the British line to cover the retreat.[61] Scheer then ordered the fleet to adopt the night cruising formation, which was completed by 23:40.[62] A series of ferocious engagements between Scheer's battleships and Jellicoe's destroyer screen ensued, though the Germans managed to punch their way through the destroyers and make for Horns Reef.[63] The High Seas Fleet reached the Jade between 13:00 and 14:45 on 1 June; Scheer ordered the undamaged battleships of the I Battle Squadron to take up defensive positions in the Jade roadstead while the Kaiser-class battleships were to maintain a state of readiness just outside Wilhelmshaven.[64] The High Seas Fleet had sunk more British vessels than the Grand Fleet had sunk German, though Scheer's leading battleships had taken a terrible hammering. Several capital ships, including SMSKnig, which had been the first vessel in the line, and most of the battlecruisers, were in drydock for extensive repairs for at least two months. On 1 June, the British had twenty-four capital ships in fighting condition, compared to only ten German warships.[65]

By August, enough warships had been repaired to allow Scheer to undertake another fleet operation on 1819 August. Due to the serious damage incurred by Seydlitz and SMSDerfflinger and the loss of SMSLtzow at Jutland, the only battlecruisers available for the operation were SMSVon der Tann and SMSMoltke, which were joined by SMSMarkgraf, SMSGrosser Kurfrst, and the new battleship SMSBayern.[66] Scheer turned north after receiving a false report from a zeppelin about a British unit in the area.[48] As a result, the bombardment was not carried out, and by 14:35, Scheer had been warned of the Grand Fleet's approach and so turned his forces around and retreated to German ports.[67] Another fleet sortie took place on 1819 October 1916 to attack enemy shipping east of Dogger Bank. Despite being forewarned by signal intelligence, the Grand Fleet did not attempt to intercept. The operation was however cancelled due to poor weather after the cruiser Mnchen was torpedoed by the British submarine HMSE38.[68] The fleet was reorganized on 1 December;[48] the four Knig-class battleships remained in the III Squadron, along with the newly commissioned Bayern, while the five Kaiser-class ships were transferred to the IV Squadron.[69] In March 1917 the new battleship Baden, built to serve as fleet flagship, entered service;[70] on the 17th, Scheer hauled down his flag from Friedrich der Grosse and transferred it to Baden.[48]

The war, now in its fourth year, was by 1917 taking its toll on the crews of the ships of the High Seas Fleet. Acts of passive resistance, such as the posting of anti-war slogans in the battleships SMSOldenburg and SMSPosen in January 1917, began to appear.[71] In June and July, the crews began to conduct more active forms of resistance. These activities included work refusals, hunger strikes, and taking unauthorized leave from their ships.[72] The disruptions came to a head in August, when a series of protests, anti-war speeches, and demonstrations resulted in the arrest of dozens of sailors.[73] Scheer ordered the arrest of over 200 men from the battleship Prinzregent Luitpold, the center of the anti-war activities. A series of courts-martial followed, which resulted in 77 guilty verdicts; nine men were sentenced to death for their roles, though only two men, Albin Kbis and Max Reichpietsch, were executed.[74]

In early September 1917, following the German conquest of the Russian port of Riga, the German navy decided to eliminate the Russian naval forces that still held the Gulf of Riga. The Navy High Command (Admiralstab) planned an operation, codenamed Operation Albion, to seize the Baltic island of sel, and specifically the Russian gun batteries on the Sworbe Peninsula.[75] On 18 September, the order was issued for a joint operation with the army to capture sel and Moon Islands; the primary naval component was to comprise its flagship, Moltke, and the III and IVBattle Squadrons of the High Seas Fleet.[76] The operation began on the morning of 12 October, when Moltke and the IIISquadron ships engaged Russian positions in Tagga Bay while the IVSquadron shelled Russian gun batteries on the Sworbe Peninsula on sel.[77] By 20 October, the fighting on the islands was winding down; Moon, sel, and Dag were in German possession. The previous day, the Admiralstab had ordered the cessation of naval actions and the return of the dreadnoughts to the High Seas Fleet as soon as possible.[78]

Admiral Scheer had used light surface forces to attack British convoys to Norway beginning in late 1917. As a result, the Royal Navy attached a squadron of battleships to protect the convoys, which presented Scheer with the possibility of destroying a detached squadron of the Grand Fleet. The operation called for Hipper's battlecruisers to attack the convoy and its escorts on 23 April while the battleships of the High Seas Fleet stood by in support. On 22 April, the German fleet assembled in the Schillig Roads outside Wilhelmshaven and departed the following morning.[79] Despite the success in reaching the convoy route undetected, the operation failed due to faulty intelligence. Reports from U-boats indicated to Scheer that the convoys sailed at the start and middle of each week, but a west-bound convoy had left Bergen on Tuesday the 22nd and an east-bound group left Methil, Scotland, on the 24th, a Thursday. As a result, there was no convoy for Hipper to attack.[80] Beatty sortied with a force of 31 battleships and four battlecruisers, but was too late to intercept the retreating Germans. The Germans reached their defensive minefields early on 25 April, though approximately 40nmi (74km; 46mi) off Heligoland Moltke was torpedoed by the submarine E42; she successfully returned to port.[81]

A final fleet action was planned for the end of October 1918, days before the Armistice was to take effect. The bulk of the High Seas Fleet was to have sortied from their base in Wilhelmshaven to engage the British Grand Fleet; Scheerby now the Grand Admiral (Grossadmiral) of the fleetintended to inflict as much damage as possible on the British navy, in order to retain a better bargaining position for Germany, despite the expected casualties. However, many of the war-weary sailors felt the operation would disrupt the peace process and prolong the war.[82] On the morning of 29 October 1918, the order was given to sail from Wilhelmshaven the following day. Starting on the night of 29 October, sailors on Thringen and then on several other battleships mutinied.[83] The unrest ultimately forced Hipper and Scheer to cancel the operation.[84] When informed of the situation, the Kaiser stated "I no longer have a navy."[85]

Following the capitulation of Germany on November 1918, most of the High Seas Fleet, under the command of Rear Admiral Ludwig von Reuter, were interned in the British naval base of Scapa Flow.[84] Prior to the departure of the German fleet, Admiral Adolf von Trotha made clear to von Reuter that he could not allow the Allies to seize the ships, under any conditions.[86] The fleet rendezvoused with the British light cruiser Cardiff, which led the ships to the Allied fleet that was to escort the Germans to Scapa Flow. The massive flotilla consisted of some 370 British, American, and French warships.[87] Once the ships were interned, their guns were disabled through the removal of their breech blocks, and their crews were reduced to 200 officers and enlisted men on each of the capital ships.[88]

The fleet remained in captivity during the negotiations that ultimately produced the Treaty of Versailles. Von Reuter believed that the British intended to seize the German ships on 21 June 1919, which was the deadline for Germany to have signed the peace treaty. Unaware that the deadline had been extended to the 23rd, Reuter ordered the ships to be sunk at the next opportunity. On the morning of 21 June, the British fleet left Scapa Flow to conduct training maneuvers, and at 11:20 Reuter transmitted the order to his ships.[86] Out of the interned fleet, only one battleship, Baden, three light cruisers, and eighteen destroyers were saved from sinking by the British harbor personnel. The Royal Navy, initially opposed to salvage operations, decided to allow private firms to attempt to raise the vessels for scrapping.[89] Cox and Danks, a company founded by Ernest Cox handled most of the salvage operations, including those of the heaviest vessels raised.[90] After Cox's withdrawal due to financial losses in the early 1930s, Metal Industries Group, Inc. took over the salvage operation for the remaining ships. Five more capital ships were raised, though threeSMS Knig, SMSKronprinz, and SMS Markgrafwere too deep to permit raising. They remain on the bottom of Scapa Flow, along with four light cruisers.[91]

The High Seas Fleet, particularly its wartime impotence and ultimate fate, strongly influenced the later German navies, the Reichsmarine and Kriegsmarine. Former Imperial Navy officers continued to serve in the subsequent institutions, including Admiral Erich Raeder, Hipper's former chief of staff, who became the commander in chief of the Reichsmarine. Raeder advocated long-range commerce raiding by surface ships, rather than constructing a large surface fleet to challenge the Royal Navy, which he viewed to be a futile endeavor. His initial version of Plan Z, the construction program for the Kriegsmarine in the late 1930s, called for large number of P-class cruisers, long-range light cruisers, and reconnaissance forces for attacking enemy shipping, though he was overruled by Adolf Hitler, who advocated a large fleet of battleships.[92]

High Seas Yacht Service

If you live in or have visited the Greater Fort Lauderdale area, chances are pretty good that you have booked a cruise on the Jungle Queen Riverboat or at the very least seen her plying the New River. First launched in 1935, Jungle Queen Riverboat cruises have been delivering a laid-back, casual cruising experience to its customers for more than 80 years.

The old fashion sternwheeler was recently hauled at LMC and our team of running gear mechanics was called upon to overhaul her running gear from shafts to seals, props and rudders as part of routine maintenance.

After performing a full running gear inspection, we pulled the shafts, props and dropped the rudders. We also installed and aligned a new babbit bearing on her shaft. Babbit bearings are known for their resistance to galling and are often used in the marine applications for vessels of this type. As part of the overhaul, we will also remove and re-install the shaft and shaft muff couplings, supply a new Tides Marine shaft seal system and four new cutless bearings.

Our in-house machine shop, Straight Line Marine, will straighten both the port and starboard main shafts as well as the tailshafts. We will then lap the props back on the shafts as well as fit, face and lap the port and starboard couplers.

Work on the rudders required us to disconnect the tie bar and tiller arms. Once the rudders were out of the vessel, we replaced the rudder packing and stuffing box hardware. Our final step will be to do a full engine alignment to ensure smooth, vibration-free cruising.

Once the work is complete and the old gal is launched again, she will be ready to delight visitors to and residents of the Venice of America for years to come.

Optical Scope Alignment check for accuracy

When a 126 Oceanco Motor Yacht was hauled at LMC, we were hired to perform an extensive overhaul on the vessels running gear. Since it had been a while since the running gear was inspected, we first performed a laser deck target before she was pulled out of the water. This is a necessary step in order to ensure that the vessel is blocked correctly for future alignment work.

As part of the overhaul, we removed the shafts, props, stern tube and dropped the rudders. This particular yacht had an older Wartsila EL shaft seal system which was difficult and expensive to maintain. For this reason, we upgraded the shaft seal system to a Wartsila PSE model. Because of space constraints and the different dimension of the two systems, we needed to work with a local aluminum welding contractor to modify the stern tubes in order to accommodate the new shaft seal system. These seals also need to be installed on the centerline of the shafts so we performed an optical scope alignment from the main struts and transmission to the stern tube to ensure exact placement.

Because of excessive wear on the main strut Thordon bearings, we removed the bearings so our in-house machine shop, Straight Line Marine, could cleaned them up before re-installing back into the vessel. Our machine shop also straightened the shafts, lapped the propellers and fit, faced & lapped the port and starboard couplers.

Once all the prep work was completed, we re-installed the propellers and propeller shafts along with the rudders, aligned the engines and performed a final laser deck targeting procedure to ensure that the vessel would not experience any vibrations under way.

Upgrading a Wartsila shaft seal system takes an experienced team, the right tools and precise coordination with outside contractors to make sure the job is done right.

While at the Fort Lauderdale International Boat Show, we were approached by the Captain of a new 164 yacht whose vessel was on display at the show. After a brief sea trial before the show, the vessel had reason to believe that the shafts were bent and Thordon bearings were damaged. While this was an unfortunate turn of events, the problem was magnified by the fact that the yacht was scheduled for a charter in the Caribbean only a week and a half after the show ended.

As you can imagine, most of the boat yards in South Florida were booked for the days following the boat show leaving this Captain with little options of getting the work done quickly. And forgoing the work for a long trip south was not an option. Get it done or cancel charters. We worked with Lauderdale Marine Center to squeeze the yacht into the haul out schedule a couple of days after the show ended.

Once hauled, our team sprang into action. While still in the blocking process, the High Seas team started pulling the props. The next day the shafts were out of the vessel and on the way to the machine shop. Fortunately, our machine shop, Straight Line Marine, is located on site at Lauderdale Marine Center. No loss of time calling for a truck to load and transport to an outside facility. Within a short period of time, the machine shop went to work on straightening. With a little overtime, the shafts were ready to install a day later.

We also found Thordon bearings that were damaged and needed to be replaced. Since this was suspected during our first meeting at the boat show, we ordered Thordon material and it was on-hand before the vessel hauled. Thordon bearings require custom machining to fit the vessel. Our machine shop got it done while the shafts were being straightened.

We then re-installed the shafts and props, did an optical scope alignment and sea trial and sent the yacht on her way in a matter of days so she could make her charter.

This Captain found himself in a tight spot but working with Lauderdale Marine Center to fit this 164-footer into the schedule, hard work on the part of the High Seas and Straight Line Marine teams, a machine shop on-site and ready to go and the dedication to customer service that is the foundation of our company, this yacht is on her way to making a charter guests dream vacation come true.

And we will be there with Lauderdale Marine Center in Booth #640. Stop by and visit with us, November 1-5 at the Bahia Mar Yachting Center. We will have our experienced technicians and mechanics in the booth from both High Seas Hydraulics and High Seas Yacht Service to answer any questions you may have on running gear or hydraulic systems. Hope to see you at the Show!

Optical Scope Alignment check for accuracy

We recently had the opportunity to work on the worlds largest sport fishing boat, a 144 Trinity. The yacht was recently sold and her new owner had her hauled at Lauderdale Marine Center for a complete refit including new engines (repower). The vessel originally had old Paxman engines that were removed by cutting a large hole in the side of the boat and replaced with new MTU engines.

A job of this size requires precision coordination with other contractors at LMC who handle engine rigging and removal, welding, plumbing, painting and full MTU service commissioning.

For our part, we first performed a laser deck targeting procedure to block the vessel properly for hull work and future alignments. We then removed the running gear from the boat so our machine shop could straighten the shafts, lap fit face couplers and propellers and ABS crack test the shafts.

Next, we performed an optical scope alignment of the remote transmissions to the shaft line and used Chockfast to hold the transmissions in place. Working closely with the aluminum fabricators and MTU engine plans, our team made sure that the new engine beds and stringers were in the right position and the right height for the new engines and engine mounts. The next step was to install the new engine mounts on the engines and rough align the engines with the transmissions using lasers for final engine room fabrication.

Our machine shop, Straight Line Marine, then machined the new sole plates for the engine mounts. We also installed Gieslinger torsional couplings between the engines and transmissions and provided all new bearings and shaft seals.

Once the vessel was launched, we did a final laser alignment of the engines to the transmissions and used Chockfast to place all engine mounts into position.

The vessel is now ready to take her owners far and wide in search of big game fish.

As discussed in a previous post, we were commissioned to perform a strut alignment on a 120 Ferretti after she ran aground. This vessel had cardan shafts. Marine cardan shafts, while fundamentally the same as u-joint shafts in cars and trucks, are unique because of the large flanges they have for higher horse power capabilities. They are commonly used with remote transmissions where the transmission (gearbox) are separate from the main engine.

Once we removed the cardan shafts from the boat, we sent them to a company in the Mid-West where they inspected and replaced where needed the needle bearings in the universal joints (U-joint) and balanced the shafts. Balancing cardan shafts takes a highly-specialized piece of equipment.

It is very important to balance the cardan shaft to eliminate the possibility of torsional vibrations. Torsional vibrations are caused by two things: the u-joint operating angle at the drive end of the drive shaft and the orientation (phasing) of the yokes at each end of the drive shaft. A torsional vibration is a twice per revolution vibration. It will cause the drive shaft, downstream of the front U-joint, to speed up and slow down twice per revolution. That means that the engine producing a constant speed of 3,000 RPM can actually be attached to the drive shaft that is changing speed 6,000 times per minute. The amount of that change in speed, called the magnitude, or size of the change, is proportional to the size of the angle at the drive end of the drive shaft, or the amount of misalignment between the yokes at the drive and driven end of your drive shaft. Torsional vibrations are serious vibrations that can cause the shaft to bend and potentially break.

When a drive shaft is assembled, its inner components usually consist of a slip yoke on one end and a tube yoke on the other end, and they are usually assembled in relation to each other. This is called PHASING. Most drive shafts are assembled with their yokes in line, or IN PHASE. A drive shaft that is in phase and has the correct operating angles at the drive end of the shaft does not create a torsional vibration. Drive shafts that are NOT in phase will vibrate with the same twice per revolution vibration as a drive shaft with incorrect operating angles.

Understanding the intricacies of the various components found in many mega-yachts ensures that the job gets done and gets done right.

When a 120 Ferretti was hauled at Lauderdale Marine Center, the captain hired us to perform shaft straightening in our machine shop, Straight Line Marineand a strut alignment on the yacht as a result of a recent grounding. The ship had significant vibration issues that needed to be addressed.

Once the struts were removed, cleaned and straightened, the re-installation began with prepping the surface to remountthe struts. Upon completion, we used a forklift and ratchet straps to reinstall the struts in the boat. To ensure exact alignment, we used an optical scope.Optical Scope Alignmentsor Scoping for short; is the most advanced method for obtaining a perfect marine shaft alignment with struts, shaft logs, engines or v-drives. Scoping is the latest generation of alignment technology and far more advanced than the old piano wire system and even laser alignments. The Optical Scope Alignment allowed our mechanics to make exact adjustments to ensure that the struts were perfectly seated to the haul.

To finish the re-installation of the struts, we use CHOCKFAST ORANGE to fill the gaps between the strut installation and the hull of the boat. CHOCKFAST is an engineered epoxy chocking material that is used to cast-in-place permanent machinery supports for all sizes and types of main engines and marine auxiliary equipment. Because it conforms precisely to any surface profile, CHOCKFAST eliminates the machining of foundation and mounting surfaces as well as the fitting of the old-style steel chocks.

CHOCKFAST Orangeisaconveniently pourable, two-component, structural epoxy chock that replaces tediously fitted steel shims (or steel chocks) assuring exact contact with machined or un-machined equipment bed plates. This is the only method to gain an accurate alignment without complicated line boring or other machining processes.

This yacht is now ready to get back on the open seas for new adventures and smooth sailing.

A 106 Westport yacht was recently hauled at Lauderdale Marine Center for a variety routine maintenance projects including shaft work, bearing replacements and an overhaul on several hydraulic systems. To streamline the process and help the captain and crew better manage the project, they contracted with both High Seas Yacht Service for the running gear portion and High Seas Hydraulics to handle the hydraulics work.

Our running gear mechanics inspected the shafts to ensure they were straight and aligned and replaced the bearings and seals. Normal wear and tear associated with running the vessel and prolonged exposure to salt water makes this task a necessary evil for properly maintaining the boat. As seen in the adjacent photo, there was a visible gap where the cutlass bearing adjoined to the shaft.

We were also commissioned to replace the seals on the lower stabilizer fins. ABT Trac, one of the more popular brands, recommends changing the lower stabilizer fin seals every couple of years but at least every six years depending on use. The components on the stabilizer are constantly working except is absolute calm seas, so the wear and tear can be considerable. After dropping the fins, we proceeded to change out the old lower stabilizer fin seals with new ones, check the hoses and cylinders, then reassembling the units.

In addition to the routine maintenance on the stabilizer systems, we flushed the entire hydraulic system using the simple drain, filter, fill approach commonly referred to in our shop as a DFF. This type of flush is more of an oil change and is part of routine maintenance. It is not appropriate where a more serious condition such as water, metal particles or other contaminants are found in the oil. The process calls for draining the hydraulic tank, changing out the filters and refilling the tank with hydraulic fluid.

To round out the work on this Westport, we did an overhaul on the bow thruster, single Maxwell windlass, the boats heat exchangers and the hydraulic steering system which was slow to respond.

From running gear to hydraulics, our teams at High Seas Yacht Service and High Seas Hydraulics, make easy work of maintaining the systems that make your vessel safe and operating smoothly.

We recently worked on a 96-foot Ferretti yacht that had run aground and was experiencing considerable engine vibrations. Our field technicians with High Seas Yacht Service inspected the boat and found that the shafts were bent and one of the struts was bent and out of alignment. After pulling the props and shafts, we sent the shafts off to our machine shop, Straight Line Marine for straightening. Once the shafts were back in true, we sent them back to the vessel for re-installation after performing a full strut alignment on the vessel.

Strut alignment is often overlooked when trying to determine the cause of vibrations in a boat. All too often the first or second course of actions are shaft straightening or engine alignment when the root of the problem may lie in the struts. Struts can be out of alignment due to poor factory set-up or a hard grounding causing a bent or twisted strut.

Strut alignments are complex and require special tools and experienced mechanics. Once a strut is removed from the boat it is a major repair and should only be done by specialist in this field.

We begin the process with an optical scope alignment for precision measurements of the misalignment. In order to align the strut, it must be removed or dropped from the bottom of the boat. All strut bolts are removed and a considerable force is applied to break the bond between the strut and the hull. Proper equipment and safety are a major concern since some struts can weigh hundreds of pounds.

Once removed, the strut pad and hull pockets must be ground clean in preparation for installation. Extra jacking holes are drilled and tapped in the four corners of the strut pads to help with fine tuning adjustments. Once preparation is complete, the strut is hung back in its original place and the optical scope is once again used for precision alignment of the strut cutlass bearing.

When the strut is properly aligned, we use ChockFast to inject into the gap between the hull and strut to form a perfect fit with the bottom of the hull.

A strut alignment is typically a one-time project for any vessel unless it is driven hard aground. A properly aligned strut will free-up an engine to provide a smooth ride for comfort and higher speed with lower fuel consumption. For more details on performing a full strut alignment, click here.

When a 112-foot Westport yacht returned to Lauderdale Marine Center, our running gear team dropped in on the vessel for a courtesy visit and health check. The ship was in the yard last year and we did a full running gear job including shaft work and alignment.

Checking Tolerances

Since the yacht was back on the hard, our team checked the cutlass bearing clearance on the shafts to ensure that the shafts were properly aligned. The tool we used to perform this task is called a feelers gauge which are an assortment of fine thickened strips with marked thickness which are used to measure gap width or clearance between the shaft and the cutlass bearings. We also visually inspected the bearing seals.

Feelers Gauge

We were happy to report back to the captain that everything checked out properly and the running gear work that we performed last year was holding true. When you engage High Seas Yacht Service, you can rest assured that we will stand by our work and go that extra mile to keep our valued customers sailing smoothly.
