‘High Seas’ Season 4 Canceled at Netflix Even After Initial Renewal

Posted: January 22, 2023 at 12:48 am

High Seas (or Alta Mar as its known in Spanish regions) will not be returning for season four on Netflix. Reports from Spain indicate that season three of the Spanish period drama is now set to be the last. Heres why Netflix isnt continuing with the show and we look back at the history of the series too.

Lets quickly recap the shows history. The period drama is among a suite of huge shows that Netflix commissioned from Spain.

The mystery series saw two women embark on a luxurious ocean cruise to Rio de Janeiro but all goes awry when a series of murders take place on the boat. High Seas was only originally envisioned as a two-season series but was stretched past its original storyline due to popularity (just like Money Heist).

The series comes from Spanish production house Bamb Producciones who is also behind other shows such as Instinto for Movistar, Enel Corredor de la Muerte and El Caso Alcasser.

Originally, Altar Mar (High Seas) was renewed for a third and fourth season. Bluper (a Spanish entertainment news portal attached to El Espanol) reported that news back in October 2019 with another sixteen chapters reportedly in development.

Just before season three touched down on Netflix in early 2020, Bluper then reported that the planned fourth season had been scrapped. It compares it to a similar tale that The Cable Girls was also supposed to get an additional season but was also scrapped.

What happened between the renewal and the cancellation? Some point to lack of marketing (a recurring criticism of Netflix) but the fourth season wouldve been filmed around the time COVID-19 came into play and that wouldve delayed High Seas production on season four into what couldve been reserved for their new upcoming Netflix series (more on that in a second).

Of course, it could simply be the case that interest wained significantly enough to not justify keeping the show going.

Although IMDb scores for the third season were more favorable, there was significantly less interest overall.

The good news is that if you enjoyed the production quality of High Seas, more shows from the same company are coming to Netflix in the future.

The new production is called Jaguar and is due for release in 2021. It stars Blanca Surez and is also a period drama but this time set in the 1960s. Well have a bigger preview on this series in due course.

Do you wish High Seas was coming back for season four? Let us know in the comments.

‘High Seas’ Netflix Review: Stream It or Skip It? – Decider

Posted: at 12:48 am

We love mysteries. Love them; great pulpy mysteries like the ones Agatha Christie wrote. But we dont see those kind of mysteries on TV anymore, ones where the people and setting are glamorous, and things are violent but not dark. The Spanish miniseries,High Seas is that kind of mystery. Read on for more about this new Netflix series

Opening Shot: A ships captain writes in his log about the three murders that have already occurred in ten days on this damned ship.

The Gist:The Villenueva sisters Eva (Ivana Baquero) and Carolina (Alejandra Onieva) are on their way to a cruise ship to take a one-way journey from Spain to Brazil. Why one way? Carolina is getting married on board and setting up a new life in Rio, while Eva, an author, is meeting a publisher who is interested in her work. As they approach the port, their car accidentally hits a young woman named Luisa (Manuela Vells), who claims that theyre going to kill me if shes caught. Eva, whos trusting and empathetic almost to a fault, convinces Carolina to stow her in their steamer trunk and sneak her on board.

Eva is confident they can get Luisa on board because Carolina is marrying the ships owner, Fernando Fabregas (Eloy Azorin), so the trunk isnt in storage. When they finally are able to get Luisa out, she says shes running from her fiance, a powerful man who demands they get married. Carolina wants to tell Fernando, but Luisa begs her to wait until theyre at sea and she cant be taken off the ship. Eva convinces her not to tell Fernando when the two of them visit him at his office just as he gets a call to meet a mysterious person at midnight.

Everyones making a new start on this cruise: The sisters just lost their father, and their uncle Pedro (Jos Sacristn) has decided to sell the business they ran together when Carolina and Eva decided not to take over. The captain is leading his first cruise since his wife died, and he wants no part of superstition like an albatross hitting the bridge right before they set sail. His first officer, Nicolas Vazquez (Jon Kortajarena), used to be a petty thief until the captain took him under his wing.

Luisa, having been taken down to the third class quarters of the sisters nanny Francisca and her daughter Victoria, knocks Francisca out, steals her key to the sisters cabin, and starts ransacking it, looking for something. As Eva gets cozy with Nicolas on the deck around midnight, though, she hears a woman scream and sees her fall from the ship. As the crew searches for the woman, both Eva and Carolina think that the woman who went overboard was Luisa, and they finally tell Fernando. But did the woman fall from the deck or was she pushed?

Our Take: High Seas(original name:Alta mar) is created by Ramon Campos and Gema R. Neira (Cocaine Coast), and its an amazingly good-looking show. Its post-WWII setting can not only be seen in the costumes and props like cameras and luggage, but the sets depicting the lavish, art deco-style hallways, ballrooms and staterooms of the luxury cruise ship the characters are on are a sight to see. Also, the costuming gives us little clues about the characters: Eva the independent artist, for instance, wears pants, which was just starting to be a thing in the late 40s.

The story plays out like one of those potboiler mysteries that Agatha Christie might have written in that time period; lots of colorful characters, all with an agenda and a motive, populate the ship, and mysteries abound. Sometimes, we thought Campos and Neira were a bit too coy with some of the mysteries, as when the ships doctor has a cryptic conversation with Uncle Pedro about what they might be doing when they arrive in Rio. But, for the most part, the characters are well-drawn and the story is intriguing.

One of the other things we found fun aboutHigh Seas is that the tone of the show isnt dark, like some of the period mysteries weve seen of late have been. No, it takes an old-fashioned approach to the murder mystery, making the setting glamorous even the third-class deck looks like a fun party instead of something resembling steerage the characters witty and sophisticated, and the mystery the central part of the story, not blood and gore. Were looking forward to seeing how this plays out over the series eight episodes.

Sex and Skin: The first episode is pretty chaste, save for the ships lothario, Sebastian (Tamar Novas) lifting Victorias socks as a way of flirting.

Parting Shot: On the deck where the woman was thrown overboard, Eva finds an engineers pin, the same one Carolina gave Fernando just before the ship set sail.

Sleeper Star:Kortajarena is intriguing as Nicolas. He has taken a liking to Eva, and their relationship on board will likely have a big influence on the mystery.

Most Pilot-y Line: Sebastian, after meeting Victoria: I hate it when she goes, but I love watching her leave. Funny line, of course, but also very cliche.

Our Call: STREAM IT.High Seas is a good-looking, light mystery with performances that signal that theyre not taking things all that seriously, which is a good thing for a show like this.

Joel Keller (@joelkeller) writes about food, entertainment, parenting and tech, but he doesnt kid himself: hes a TV junkie. His writing has appeared in the New York Times, Slate, Salon, VanityFair.com, Playboy.com, Fast Companys Co.Create and elsewhere.

The ocean covers about two thirds of the surface of our planet and houses 50-80% of all life on Earth. Most of us are more familiar with inshore ecosystems, like tidepools, mangroves, and kelp forests, but did you know that 64% of the ocean is considered the high seas? The high seas are some of the most biologically productive in the world teeming with plankton and home to ocean giants like predatory fish, whales, and sharks. The seabed sequesters tremendous amounts of carbon and the ocean volume traps heat, slowing the effects of climate change on land and in the atmosphere dramatically.

This schematic shows the legal boundaries of maritime zones of the ocean and air space. Image courtesy of Tufts University, Law of the Sea: A Policy Primer, Chapter 2: Maritime Zones. Download image (jpg, 106 KB).

Coastal countries generally control the 200 nautical miles of ocean that is, the water column and seafloor extending out from their coasts. These 200 nautical miles are known as a countrys exclusive economic zone (EEZ), where the exploration and use of marine resources is a sovereign right. The high seas refers to the ocean water column that lies beyond the boundaries of any one country, also known as areas beyond national jurisdiction (ABNJ).

The seafloor beyond the limits of the coastal continental shelf is what is termed the Area by the 1982 United Nations Convention on the Law of the Sea (UNCLOS). The International Seabed Authority (ISA) is mandated to regulate the exploration for, and exploitation of, seabed mineral resources in the Area for the benefit of humankind.

On this map, exclusive economic zones are shown in white and high seas, or areas beyond national jurisdiction, are shown in light green. Image courtesy of Sumaila et al. In prep./ Global Ocean Commission/ The High Seas and Us: Understanding the Value of High-Seas Ecosystems. Download image (jpg, 228 KB).

The ISA has the power to allocate certain parts of the Area to countries for exploration and mining. However, many other activities (like fishing and shipping) also occur on the high seas, and a number of regional and sectoral organizations with different responsibilities contribute to its governance, which has been characterized as fragmented.

Since 2017, an Inter-Governmental Conference established by the United Nations General Assembly has been negotiating an agreement under UNCLOS that would allow for more effective management and protection of the high seas. This internationally legally binding instrument is often referred to as the Biodiversity in Areas Beyond National Jurisdiction treaty, or BBNJ treaty.

This treaty focuses on four main areas:

Although the final form of the BBNJ treaty has still to be agreed upon, it seems likely at this point that the treaty will have a Conference of the Parties (COP) that will have some level of centralized decision-making power over aspects of the conservation and sustainable use of biodiversity in ABNJ. Additionally, existing sectoral and regional organizations that already have regulatory competence (or authority) in ABNJ will likely retain that competence, but might be given wider responsibilities. The exact balance between the COP and the regional and sectoral organizations has still to be agreed upon.

The fourth round of negotiations on the BBNJ treaty came to a close in late March 2022, but member states failed to agree on a treaty. The next, and hopefully final, round of negotiations is set to take place from August 15-26, 2022, in New York, New York.

Florida:

For Florida Residents, Legislation Effective 7/1/2004: Direction on appropriate utilization of emergency services and alternative urgent care services. Choosing the Right Health Care Setting:

Emergency Rooms: When you or a loved one is hurt, you want the best care. Deciding where to go isn't always easy. You may be tempted to go to the emergency room (ER). But, this may not be the best choice. At the ER, true emergencies are treated first. Other cases must wait--sometimes for hours. And, it may cost you more. Go to the ER for heavy bleeding, large open wounds, sudden change in vision, chest pain, sudden weakness or trouble talking, major burns, spinal injuries, severe head injury or difficulty breathing. Of course, each case is unique. If a situation seems life-threatening, take action. Call 911 or your local emergency number right away.

Urgent Care: Sometimes, you may need care fast. But, a trip to the ER may be unnecessary. You may want to try an urgent care center. They can treat many minor ailments. Chances are, you won't have to wait as long as at the ER. You may pay less, too. An urgent care center can help with: sprains, strains, minor broken bones, mild asthma attacks, minor infections, small cuts, sore throats or rashes.

Clinical Care: If it's not urgent, it's usually best to go to your own doctor's office. Your doctor knows you and your health history. He or she can access your medical records. And, he or she can provide follow-up care or refer you to specialists.

12 Ways to Treat Psoriasis at Home – Healthline

Posted: at 12:42 am

Psoriasis is a recurring autoimmune disorder that affects more than 7.5 million American adults.

It tends to appear pink or red, usually with silvery-white scales, on those that have fair to light skin tones. On medium skin tones, it may look salmon-colored with a silvery-white scale, and on darker skin tones, it could look violet and the scale gray. Or it can also appear dark brown and difficult to see.

Even though it affects your skin, psoriasis actually begins inside your body in your immune system.

Psoriasis is a condition where your T-cells, a type of white blood cell, can become overactive to produce other immune markers that can cause an inflammatory reaction on the skin. The reaction on the skin shows up in the form of silvery-white scale, depending on the skin ton

Even though theres no cure, many treatments exist to ease the symptoms of psoriasis. Here are 12 ways to manage mild symptoms at home.

Dietary supplements may help ease psoriasis symptoms from the inside.

Fish oil, vitamin D, milk thistle, aloe vera, Oregon grape, and evening primrose oil have all been reported to help ease mild symptoms of psoriasis, according to the National Psoriasis Foundation.

Check with your doctor before taking supplements to make sure they dont interfere with other health conditions you may have or medications youre taking.

Use a humidifier to keep the air in your home or office moist. This can help prevent dry skin before it starts.

Moisturizers for sensitive skin can keep your skin supple and moisturized.

Aloe vera has been shown in some cases to reduce redness and irritation caused by psoriasis. A 2010 study found aloe vera gel cream to be slightly more effective in improving psoriasis symptoms compared to 0.1 percent triamcinolone acetonide, a steroid cream used to treat psoriasis.

More research is needed to show for sure if aloe vera can improve symptoms of psoriasis. However, the risk of trying aloe vera gels or creams is low, so it may be worth a try.

Most soaps and perfumes have dyes and other chemicals in them that may irritate your skin. They can make you smell great, but they also can inflame psoriasis.

Avoid such products when you can, or choose those with sensitive skin labels.

Diet may play a role in managing psoriasis.

Limiting red meat, saturated fats, refined sugars, carbohydrates, and alcohol may help reduce flare-ups triggered by such foods.

Cold water fish, seeds, nuts, and omega-3 fatty acids are known for their ability to reduce inflammation. This can be helpful for managing psoriasis symptoms.

Olive oil may also have soothing benefits when applied topically to the skin. Try massaging a few tablespoons on your scalp to help loosen troublesome plaques during your next shower.

A lukewarm bath with Epsom salt, mineral oil, milk, or olive oil can soothe the itching and infiltrate scales and plaques. Oatmeal baths can also be very helpful and soothing for plaque psoriasis.

Be sure that the water is not hot. Hot water can cause more irritation.

Moisturize immediately after your bath for double benefits.

Light therapy involves exposing your skin to ultraviolet light under the supervision of a doctor.

Ultraviolet light can help slow the growth of skin cells triggered by psoriasis. This therapy often requires consistent and frequent sessions. Sitting in the sun for 10 to 15 minutes can also help reduce plaques.

However, too much sunlight and tanning beds arent the best options as they can also increase your risk of skin cancer.

Light therapy should always be done under the supervision of a doctor.

Any chronic condition like psoriasis can be a source of stress, which in turn can worsen psoriasis symptoms.

In addition to reducing stress whenever possible, consider incorporating stress-reducing practices such as yoga and meditation.

Alcohol is a trigger for many people who have psoriasis.

A study in 2015 found an increased risk of psoriasis among women who drank nonlight beer. Those who drank at least five nonlight beers per week were nearly twice as likely to develop psoriasis compared to women who didnt drink.

Herbs are commonly used to treat many conditions.

Turmeric has been found to help minimize psoriasis flare-ups. It can be taken in pill or supplement form, or sprinkled on your food.

Talk to your doctor about the potential benefits for you.

Avoid tobacco. Smoking may increase your risk of psoriasis.

If you already have psoriasis, it can make your symptoms more severe.

Being overweight or obese puts you at a greater risk of developing psoriasis. Obesity is also associated with more severe psoriasis symptoms. Studies have found that losing weight can help improve these symptoms.

Here are some tips for losing weight:

There isnt a single answer for keeping the symptoms of psoriasis at bay. What works for one person may not work for another.

Some treatment options may have negative side effects for preexisting conditions other than psoriasis.

While these remedies for psoriasis may help with mild cases, prescription therapy is required for more severe cases. Talk to your doctor before seeking treatment on your own.

Read this article in Spanish.

A dermatologist can treat the thick, red, scaly patches of skin (also known as plaques) from psoriasis. They can also treat other parts of your body that moderate to severe psoriasis may affect, such as your scalp and nails. Consider checking with your dermatologist when you experience a flare or worsening symptoms.

Nearly a third of people with psoriasis develop a condition called psoriatic arthritis. This can cause swollen, stiff, or painful joints. A rheumatologist can determine if you have psoriatic arthritis and prescribe treatments to control your symptoms. This type of doctor specializes in treating arthritis and other musculoskeletal disorders.

Psoriasis has been linked to other health conditions, such as lymphoma, heart disease, diabetes, and high blood pressure. A primary care doctor can help you find ways to reduce your risk of other conditions and improve your overall health. They can also screen you for early warning signs of psoriasis complications and refer you to a specialist, if necessary.

While psoriasis has no cure, it can be treated with a variety of prescription medications (like immunosuppressive drugs) and over-the-counter drugs (such as topical ointments). A pharmacist can provide information and tips on following your treatment plan and can make sure your medications are safe to take together. They can also answer questions or address concerns about your medications.

Stress has been shown to be a trigger for psoriasis flares. A psychologist, licensed professional counselor, or clinical social worker can help you develop personalized ways to manage stress. Self-care techniques such as breathing exercises, journaling, meditation, yoga, and stretching can also help you ease stress.

Cutting back on foods that trigger psoriasis flares can help reduce symptoms. A dietitian can help you develop a nutritious eating plan that may potentially reduce inflammation in the body. They can also help you maintain a healthy weight to avoid obesity and reduce your risk of psoriasis-related complications, such as diabetes and heart disease.

Quantum Physics | What is Quantum Theory? – Video & Lesson Transcript …

Posted: at 12:38 am

Origin of Quantum Theory

In the 1900s, the field of Physics seemed, for the briefest time, to be at a halt. We were, however, at the brink of the discovery of one of the most revolutionary theories proposed to date: quantum physics. This theory was developed by a German physicist named Max Planck: he proposed that the energy of electromagnetic waves, unlike previously thought, was not a continuum, but rather, that there was a minimal, unbreakable, quantifiable unit of energy, that we call quanta. Plank's theory was shortly thereafter extended by Einstein, who found that the quantization of radiation provided an explanation for the photoelectric effect.

A lot of experiments, including the double-slit experiment by the famous mathematician Thomas Young, and Einstein's aforementioned photoelectric effect, provided extensive proof that waves and particles were not two different physical objects, but rather, that at a small enough scale, particles exhibit wave-like behavior, and electromagnetic waves (that is, light) behave as if they were tiny massless particles made of units of energy: the famous quanta. Wener Heisenberg would further build on this idea of particle-wave duality and postulate in 1927 one of the main axioms of quantum mechanics: the uncertainty principle. This theorem tells us that, for subatomic particles, we cannot exactly measure simultaneously their position and their velocity, giving a fundamental limit to measurements, a property that is based on the wave-like nature of particles.

Finally, it was Paul Dirac and Erwin Schrodinger who formulated the mathematical framework that tied together atomic theory with quantum mechanics. They developed the Schrodinger equation, which allows us to compute the wavefunction of a quantum system, and the more general, relativistic version, called the Dirac equation. Their work ultimately led to both of them winning a Nobel prize in Physics in 1933.

The fundamental postulates of quantum theory are:

In simpler terms, a wavefunction is a probabilistic description of a system. Many times it is said that a quantum system can be in a superposition of different states, and indeed, the wavefunction represents all of the possible states on which you can find a quantum particle (for example, all of the different possible positions) and their associated probability.

$$i hbar frac{partial}{partial t}Psi(t,x) = left( - frac{hbar ^2} {2m} frac{partial^2}{partial x^2 } + V(t,x) right) Psi(t,x) $$

This equation appears difficult at first sight, but it can be broken down into pieces in the following way: the left-hand side of the equation indicates the time evolution. {eq}hbar {/eq} is the plank constant, which gives us a sense of the energy scale of the system we are working with. On the right-hand side, we find two different terms, the first one involving the velocity of the particle, and thus corresponding to the kinetic energy, and the second one, {eq}V(t,x) {/eq}, corresponding to the potential energy.

When we measure a particle, the wavefunction is said to "collapse" - that is, the particle will not be in a superposition of states with associated probabilities anymore, but in a definite single state, corresponding to the measured quantity.

These principles have many consequences and have been used to derive many important theorems, but two of them are the most notable: Heisenberg's uncertainty principle and the existence of entanglement.

As mentioned before, Heisenberg's uncertainty principle states that one cannot know with perfect accuracy both the position and the velocity of a quantum particle. Plainly said, there is a fundamental limit on the information one can extract out of a quantum system, and this is because when we measure a particle and the wavefunction collapses, there is a loss of information happening during that collapse. Another way to understand this principle is to think about it in practice: Let's say that we have an electron and that we wish to measure its location. For that, we would need to look at the electron, either by shining a laser at it or by taking a photograph. Both processes are invasive and disrupt the state of the electron, causing a change in its internal energy, since we would be bombarding it with a ray of light. This change of energy, which is needed to determine the position, will affect the velocity of the electron. Therefore, we cannot know with exactitude the speed of the electron anymore. the same happens if we try to measure the velocity: in that case, it will be the position of the electron the one we would not be able to determine exactly.

Entanglement is a different phenomenon that occurs when two quantum particles interact. Sometimes, two interacting quantum particles can stay connected - in quantum terms this means that instead of there being two different wavefunctions, one representing each particle, there is a bigger, single wavefunction representing both of them at the same time. The result is that both of these particles stay connected, and can influence each other even if they are thousands of miles apart. The coolest (and most spooky!) thing is that, because we know that measurements affect the state of a quantum system, that means that if you separate two entangled particles and then you measure the state of one of them, the state of the other one will immediately be affected as well, no matter how far it is located.

Let's try to clarify all of these ideas with a famous example: Schrodinger's Cat.

This is a thought experiment that is aimed at illustrating the concept of superposition. Let's say we have a hypothetical cat, and that we put it inside of a box with poison, and then we close the box. We will also assume that the cat has a 50/50 chance of eating the poison. Therefore, until we open the box, we do not know with certainty if the cat will be dead or alive - there is a 50/50 chance of him being either. At that stage, if we imagine that the cat is a quantum particle, we can write the cat's wavefunction, for example, to be something like this:

$$Psi = 0.5 |text{dead}> + 0.5 |text{alive}> $$

This means that the cat is in a state which is a superposition of dead and alive: it is dead with a 50% chance, and alive with a 50% chance. Let's say that we now open the box, and find that the kitty is alive. The measurement, or the act of opening the box, has made the wavefunction collapse, and now we find the cat in a state of 100% aliveness.

Another spooky and plain amazing phenomenon that quantum particles can exhibit is that of quantum tunneling.

In the classical world, when you throw a ball against a wall, you know exactly what will happen. The wall acts as a barrier that is impenetrable, and the ball will certainly bounce back. However, this is no longer true for quantum particles. Given that quantum particles can be in a superposition of position states, they sometimes exhibit really spooky characteristics. When you throw a quantum particle against a barrier, there might be a small probability of finding the particle on the other side of the barrier. This means that, if you repeat the experiment again and again measuring the position of the particle right after hitting the barrier, while most of the times you will find that the quantum particle bounced back, a small portion of the times you will find the particle on the other side of the barrier: this is called quantum tunneling.

Today we learned that Quantum Theory is the branch of physics that studies atomic and subatomic particles, and their associated phenomena. It was developed in the early 1900s by Max Plank, and the theory was extended by many physicists including Einstein, Heisenberg, Dirac, and Schrodinger.

Quantum particles are described by a wavefunction, and when we observe them (that is when we measure them) we can alter their state. Quantum particles can be found in a superposition of states, but we do not know which one until we measure them: this is best exemplified by the hypothetical Schrodinger's cat, a thought experiment consisting of putting a cat on a box with poison, which results in the cat being in a superposition of dead and alive, with the observer not knowing until they open the box.

Some important principles of Quantum theory include the Heisenberg uncertainty principle, which indicates that we cannot know with perfect accuracy both the position and the velocity of a quantum particle, and the existence of entanglement, a long-range interaction effect that interacting quantum particles can have on one another.

Eugenics: Definition, Movement & Meaning – HISTORY – HISTORY

Posted: at 12:36 am

Contents

Eugenics is the practice or advocacy of improving the human species by selectively mating people with specific desirable hereditary traits. It aims to reduce human suffering by breeding out disease, disabilities and so-called undesirable characteristics from the human population. Early supporters of eugenics believed people inherited mental illness, criminal tendencies and even poverty, and that these conditions could be bred out of the gene pool.

Historically, eugenics encouraged people of so-called healthy, superior stock to reproduce and discouraged reproduction of the physically or mentally challengedor anyone who fell outside the social norm. Eugenics was popular in America during much of the first half of the twentieth century, yet it earned its negative association mainly from Adolf Hitler and his obsessive attempts to create an advanced Aryan race.

Modern eugenics, more often called human genetic engineering, has come a long wayscientifically and ethicallyand offers hope for treating many devastating genetic illnesses. Even so, it remains controversial.

Eugenics literally means good creation. The ancient Greek philosopher Plato may have been the first person to promote the idea, although the term eugenics didnt come on the scene until British scholar Sir Francis Galton coined it in 1883 in his book, Inquiries into Human Faculty and Its Development.

In one of Platos best-known literary works, The Republic, he wrote about creating a superior society by procreating high-class people together and discouraging coupling between the lower classes. He also suggested a variety of mating rules to help create an optimal society.

For instance, men should only have relations with a woman when arranged by their ruler, and incestuous relationships between parents and children were forbiddenbut not between brother and sister. While Platos ideas may be considered a form of ancient eugenics, he received little credit from Galton.

In the late 19th century, Galtonwhose cousin was Charles Darwinhoped to better humankind through the propagation of the British elite. His plan never really took hold in his own country, but in America it was more widely embraced.

Eugenics made its first official appearance in American history through marriage laws. In 1896, Connecticut made it illegal for people with epilepsy or who were feeble-minded to marry. In 1903, the American Breeders Association was created to study eugenics.

John Harvey Kellogg, of Kelloggs cereal fame, organized the Race Betterment Foundation in 1911 and established a pedigree registry. The foundation hosted national conferences on eugenics in 1914, 1915 and 1928.

As the concept of eugenics took hold, prominent citizens, scientists and socialists championed the cause and established the Eugenics Record Office. The office tracked families and their genetic traits, claiming most people considered unfit were immigrants, minorities or poor.

The Eugenics Record Office also maintained there was clear evidence that supposed negative family traits were caused by bad genes, not racism, economics or the social views of the time.

Eugenics in America took a dark turn in the early 20th century, led by California. From 1909 to 1979, around 20,000 sterilizations occurred in California state mental institutions under the guise of protecting society from the offspring of people with mental illness.

Many sterilizations were forced and performed on minorities. Thirty-three states would eventually allow involuntary sterilization on whomever lawmakers deemed unworthy to procreate.

In 1927, the U.S. Supreme Court ruled that forced sterilization of the handicapped does not violate the U.S. Constitution. In the words of Supreme Court Justice Oliver Wendell Holmes, three generations of imbeciles are enough. In 1942, the ruling was overturned, but not before thousands of people underwent the procedure.

In the 1930s, the acting governor of Puerto Rico, Rafael Menendez Ramos, implemented sterilization programs for Puerto Rican women. Ramos claimed the action was needed to battle rampant poverty and economic strife; however, it may have also been a way to prevent the so-called superior Aryan gene pool from becoming tainted with Latino blood.

According to a 1976 Government Accountability Office investigation, between 25 and 50 percent of Native Americans were sterilized between 1970 and 1976. Its thought some sterilizations happened without consent during other surgical procedures such as an appendectomy.

In some cases, health care for living children was denied unless their mothers agreed to sterilization.

As horrific as forced sterilization in America was, nothing compared to Adolf Hitlers eugenic experiments before and during World War II. And Hitler didnt come up with the concept of a superior Aryan race all on his own. In fact, he referred to American eugenics in his 1934 book, Mein Kampf.

In Mein Kampf, Hitler declared non-Aryan races such as Jews and Romani as inferior. He believed Germans should do everything possible, including genocide, to make sure their gene pool stayed pure. And in 1933, the Nazis created the Law for the Prevention of Hereditarily Diseased Offspring, which resulted in thousands of forced sterilizations.

By 1940, Hitlers master-race mania took a terrible turn as hundreds of thousands of Germans with mental or physical disabilities were killed by gas or lethal injection.

During World War II, concentration camp prisoners endured horrific medical tests under the guise of helping Hitler create the perfect race. Josef Mengele, an SS doctor at Auschwitz, oversaw many experiments on both adult and child twins.

He used chemical eyedrops to try and create blue eyes, injected prisoners with devastating diseases and performed surgery without anesthesia. Many of his patients died or suffered permanent disability, and his gruesome experiments earned him the nickname Angel of Death.

In all, its estimated eleven million people died during the Holocaust, most of them because they didnt fit Hitlers definition of a superior race.

Thanks to the atrocities of Hitler and the Nazis, eugenics lost momentum in after World War II, although forced sterilizations still happened. But as medical technology advanced, a new form of eugenics came on the scene.

Modern eugenics, better known as human genetic engineering, changes or removes genes to prevent disease, cure disease or improve your body in some significant way. The potential health benefits of human gene therapy are impressive since many devastating or life-threatening illnesses could be cured.

But modern genetic engineering also comes with a potential cost: As technology advances, people could routinely weed-out what they consider undesirable traits in their offspring. Genetic testing already allows parents to identify some diseases in their child in utero, which may cause them to terminate the pregnancy.

This is controversial, since what exactly constitutes negative traits is open to interpretation, and many people feel that all humans have the right to be born regardless of disease, or that the laws of nature shouldnt be tampered with.

Much of Americas historical eugenics efforts such as forced sterilizations have gone unpunished, although some states offered reparations to victims or their survivors. For the most part, though, its a largely unknown stain on Americas history. And no amount of money can ever repair the devastation of Hitlers eugenics programs.

As scientists embark on a new eugenics frontier, past failings can serve as a warning to approach modern genetic research with care and compassion.
