Waltham lab develops the world’s ‘blackest black’ paint – The Boston Globe
Posted: August 4, 2017 at 1:29 pm
Above: Black Iron Ursa was made using Singularity Black paint.
SOMERVILLE That the gummy bear was an artwork was unusual.
That the gummy bear was so black that it looked like an optical illusion was really unusual.

Welcome to the world of Singularity Black.
Black Iron Ursa, a painted sculpture, doesnt reflect light, making it difficult to see its ears and paws. Because the human eye is trained to look for light, it is disorienting and somewhat painful to look at.
Get The Weekender in your inbox:
The Globe's top picks for what to see and do each weekend, in Boston and beyond.
Black Iron Ursa was the brainchild of Somerville artist Jason Chase, who watched baffled visitors stare at the object in his studio on a recent Sunday afternoon.
Made from cast iron, the gummy bear was coated in Singularity Black, a carbon nanotube paint developed by Waltham-based NanoLab, Inc. The paint absorbs over 99.9 percent of light, making three-dimensional objects look two-dimensional. Chase built a colorful wooden carousel to display the bear on, making the bears blackness even more striking. A small glass dome covers the artwork to protect it.
The paint is really fragile, Chase said. If you touch it, its going to flake off, kind of like when you touch a butterflys wings.

The blackest black paint has been a point of contention in the art world since 2014, when British artist Anish Kapoor received exclusive rights to working with Vantablack , a pigment created by a British company, Surrey NanoSystems, that absorbs 99.965 percent of light.
This arrangement frustrated other artists. In response, British artist Stuart Semple created the worlds pinkest pink and the worlds glitteriest glitter, which he made available in 2016 to everyone except Kapoor. (Kapoor managed to get his hands on the pink pigment anyway and posted a photograph of it on Instagram, taunting Semple.)
Now Chase is hoping that Singularity Black will put the whole squabble to bed.
Im really honored to be part of the launching process, he said. I remember reading about Vantablack when it came out and wanting to work with it. I hope that this means the whole art world gets to move forward.
NanoLab created Singularity Black at NASAs request in 2011. The agency frequently sends equipment into space to measure faint stars, and they wanted a pigment that would absorb stray light to keep it from interfering with sensors. Its name was inspired by the center of a black hole, where the known laws of physics stop operating.
Carbon nanotubes excel at trapping light, so the lab combined them with a binding agent for stabilization. After the pigment is applied to an object, it has to be heated to 600 degrees Fahrenheit, which eliminates the binder and leaves the carbon nanotubes in a porous arrangement for maximum light absorption.
Colin Preston, a senior research scientist on the project, noticed that Surrey NanoSystems had developed its similar product and licensed the rights to Kapoor. (NanoLab conceived the formula for Singularity Black independently, according to Preston.)
I was honestly kind of confused by that, he said. When we were done developing the pigment, we really wanted to develop our product to be commercial.
Preston had met Chase in a Drawing in Pubs class, so he e-mailed him as soon as NanoLab had successfully developed Singularity Black into a paint.
Chase, who is primarily a painter, had been working with renderings of gummy bears for a while. He made the cast-iron gummy bear a while back, during a workshop, so he dug it up and brought it to the lab for a paint job. The artwork will be displayed at Laconia Gallery , in the South End, starting Aug. 24.
Artists can buy Singularity Black off the shelf. They can apply the paint themselves after a tutorial from NanoLab, according to Preston. He estimated current price to be in the low to mid-hundreds of dollars for 250 milliliters to 1 liter of paint.
Colorado sculptor Sean OMeallie said he is intrigued by the material. He said Singularity Black opens up possibilities of doing something different and challenging.
Painting something in Singularity Black will make it harder for viewers to see a silhouette, he said. It might be a way of making art a little more hidden.
However, there are limitations to how Singularity Black can be used. It can only be applied to metal surfaces, so Chase is experimenting on copper plate. He said he wants to juxtapose traditional mediums, like oil and gold leaf, with this futuristic paint.
Preston said NanoLab has already received multiple inquiries from artists interested in getting the paint. Chase said he intends to curate an art show of Singularity Black pieces as soon as there is a collection.
I think itll fit really well in surrealist images, he said. The best thing about this paint being available to everyone is that well get to push the boundaries of the art world with it.

Proposal by A Better Ascension to change parish executive will go … – The Advocate
Posted: at 1:26 pm
DONALDSONVILLE The proposal by the group A Better Ascension to eliminate the elected Ascension Parish president position in favor of a more autonomous, appointed parish manager won't make it to the ballot this fall as the plan's backers had hoped.
Ascension Parish Council Chairman Bill Dawson announced Thursday night he is establishing a council committee to hold at least three public meetings on the plan before the full council decides whether to put the measure before the voters. One of those meetings will have to be in west Ascension.
Reading from a statement, Dawson said the committee will have the "specific task of publicly vetting the charter amendments proposed by A Better Ascension." Dawson said the new committee will be composed of the entire 11-member council.
Backers of the A Better Ascension proposal want to make major changes to the parish home rule charter, which is Ascension's plan of government, to create the new parish manager position in a bid to improve efficiency and insulate the parish executive from political back and forth.
The creation of the committee by Dawson means three groups will be holding public meetings on A Better Ascension's plan in the coming weeks and months, including another Parish Council committee and A Better Ascension itself.
GONZALES With an attempted bribery indictment hanging over the head of Ascension Parish Pr
Amendments to the home rule charter require a vote of the public. At least two-thirds of the council, or eight members, must vote to put proposed charter changes on the ballot.
The proposal would mean the parish executive would not be directly elected by voters, as the parish president is now, but would be selected by the Parish Council after nomination by a separate committee of primarily business leaders.
The proposal has already drawn opposition from sitting Parish President Kenny Matassa, his 2015 election runoff opponent surveyor Clint Cointment, and some council members. But other members expressed openness to the idea.
Dawson had said earlier there was likely a window to get the measure on the November ballot if the council had been able to vote on the proposal by the end of this month. But Dawson said Thursday the committee of the whole chairman won't make his first progress report to the Parish Council until mid-September.Dawson has named Councilman Travis Turner as chairman of the new committee and Councilman Aaron Lawler as the vice chairman.
Separate from Dawson's initiative, Councilman Daniel "Doc" Satterlee also called for discussion of A Better Ascension's proposal before the committee he chairs, the Council Strategic Planning Committee, which meets 6:30 p.m. Aug. 10 at the Parish Courthouse Annex in Gonzales.
A Better Ascension, the nonprofit group of business people pushing the measure, is also planning public meetings later this month.
JHudson, a spokesman for A Better Ascension, said before the council meeting Thursday that the group's members respect "the process and are looking forward to sharing our message of professionalism, accountability, and efficiency throughout Ascension."
"Ultimately, the charter belongs to the people of Ascension," Hudson said. "Their voices deserve to be heard regarding these changes."
A Better Ascension is composed of business leaders from Ascension, including Eatel Corp. President John Scanlan and LABI political action committee director and Republican pollster and strategist John Diez Jr., a Gonzales native.

Helsley’s ascension to the pros infused with heartbreak, triumph and promise – Tahlequah Daily Press
Posted: at 1:26 pm
TULSA He sat in his Sequoyah High School classroom, wondering what would become of his next 12 hours. Further in town, in a stuffy courtroom, Ryan Helsley was having his short-term future pleaded over.
Same went for some of his closest friends and teammates.
Turns out, Nov. 2, 2012 was an unusual day from beginning to end.
A small collection of Sequoyah football players was having temporary court injunctions filed on their behalves, after the Oklahoma Secondary School Activities Association ruled that Sequoyah players had violated its summer camp policy. The governing body over Oklahomas high school sports had all but neutered Sequoyahs 2012 football season.
The Indians were 8-1 and steamrolling to the Class 3A playoffs with the likes of Brayden Scott at quarterback and Kyle Helsley at running back. Mix in Ryan Helsley, all over the field, Karter Woodruff, Robert Smith, Cody Hooper, Nick Kingfisher, Greyden Elrod and others, and the Indians were well-equipped to wreck havoc on the 3A playoff field.
The Helsley brothers, and their Sequoyah teammates, were granted permission to play in the regular season finale by Cherokee County District Judge Douglas Kirkley. The Indians went out and ambushed Lincoln Christian on Thompson Field, 63-40, thanks to Kyle Helsleys 265 yards and three touchdowns on only 14 carries.
It would be the last time Sequoyah fielded a football team during the 2012 campaign. The OSSAA released a 3A playoff bracket the next day, leaving the Indians off while forcing Sequoyah to forfeit all of its victories it had amassed during the season.
Nearly a year later, the state supreme court ruled the OSSAA acted in an arbitrary and capricious manner, while interpreting and enforcing its rules. By that time though, it was a moot point related to the Indians run that season.
It still irks Ryan Helsley to this day.
At the time, it was heartbreaking, Helsley said. We knew how good we were, and we had a chance to do something special.
Thus, Helsleys football career was over. But as it turns out, baseball has worked out quite well for the Sequoyah graduate.
After a collegiate career at Northeastern State, Helsley was drafted by the St. Louis Cardinals. On Tuesday night, he made his Double-A debut with the Springfield Cardinals, throwing 92 pitches over four innings while not factoring into the decision in what became a 5-4 Tulsa win.
Its been an awesome journey so far, said Helsley, who gave up one run on five hits with six strikeouts and four walks against the Drillers at ONEOK Field, where several hundred loyal Sequoyah followers flocked on Tuesday.
Monday was trade-deadline day for major league ball clubs, but it was a relatively quiet day for the Redbirds. With trade winds swirling, minor league promotions went under the radar, much like Helsleys promotion from Single-A Palm Beach in Florida.
I got the call-up, and I looked at the schedule and saw the team was here in Tulsa, Helsley said. I called my mom and was a little emotional, just because I hadnt seen them in so long since I was so far from home. But it was a great blessing to be able to debut here in front of my own family.
Helsley, a 6-foot-1 right-handed hurler, began his rapid ascension through the Cardinals minor league system in 2015 after being drafted in the fifth round by St. Louis. In 2015, he pitched at the rookie-league ranks in Johnson City, Tennessee, and that segued into a 2016 season at Class A Peoria last year.
In 17 starts last season, Helsley registered a 1.61 earned run average while logging 109 strikeouts to only 19 walks. That was enough to vault him onto the top 30 list of St. Louis prospects, where he currently resides at No. 25.
For now, Helsley will look to stick with Springfield through the end of this season and re-evaluate from there.
Im going to pitch while Im healthy and make every start I can, said Helsley, who toted a 2.69 ERA in 16 starts for Palm Beach earlier this season. I just want to pitch every five days and see where it goes from there.
And as for the injustice levied by the OSSAA, Helsley sees it as nothing more than a memory now.
For the ruling to come out a year (after we graduated), it was already in the past, he said. It sucked. You think back on it and think, what if? Weve all moved then, even though it sucked then. But it is what it is.

The Downsides of John Kelly’s Ascension – Defense One – Defense One
Posted: at 1:26 pm
The former Marine general is unlikely to succeed in his new job, even as his appointment contributes to the decay of American civil-military relations.
Donald Trump is not much of a man. He feels sorry for himself, he whines, he gropes women; he bullies the weak. He brags and he lies. As a young man, this self-proclaimed athlete collected five draft deferments rather than wear his countrys uniform. He doesnt even work out. The motto emblazoned on Trumps bogus coat of arms should probably be faithless, which makes it odd that he has picked as his chief of staff a general steeled in a service whose motto is ever faithful. (The Trump coat of arms wasreportedly liftedfrom another family, with the motto integrity replacedinevitablybyTrump.)
John Kelly, retired Marine four-star and new White House chief of staff, has been throughout his career everything Trump is not: He has endured more than Trump could imagine, and has displayed virtues that Trump may not understand and certainly has not exhibited, among them candor, courage, and discipline. Which is why some observers have welcomed Kellys hiring as evidence that perhaps the president is learning, that maybe now we will have a disciplined White House that will focus on the business of public policy. Maybe the early morning tweets will diminish or evenstop.
Trumps pick of Kelly is probably better understood in a broader and darker context. That includesa speechthat he gave the same day to New Yorks Suffolk County Police Department calling on cops to bang suspects heads into squad cars; the brusque, uncoordinateddismissalof transgender service personnel by presidential tweet; aspeecha week earlier at the commissioning of USSGerald R. Fordurging sailors to lobby their representatives; a harangue to 30,000 Boy Scouts that includeda rant about loyalty, and that earned him an astonishing rebuke from the head of the Boy Scouts of America; and a longer history of toying around the edge of inciting violence, to includethe assassination of his opponentin the lastelection.
As the coils of the Russia investigation grow tighter, as his failures in Congress mount, Trump reaches for what he knowsdemagoguery of the rawest sort. He reaches as well for what he thinks of as his base, which includes (he believes) the military, many of whose leaders are actually quietly appalled by what he represents. He has picked Kelly not because of his political or administrative skills but because he thinks of him as a killera term of praise in his lexicon, which is why he likes referring to his secretary of defense as Mad Dog Mattis, a nickname the former general rejects. Kelly will not organize Goon Squads for Trump, but the president would probably not mind if he did. More to the point, Kellys selection, and that of a foul-mouthed financier from New York as Trumps communications director, tells us not that Trump is planning on moderating his behavior, but rather on going to the mattresses. He just may have picked the wrong guy for that mission, thatsall.
Kellys decision to take the job lends itself to multiple explanations. It may be an irresistible call to duty by someone who thinks of the president mainly as commander-in-chief; it may be an act of deep, quiet patriotism by someone who intends to shield the country from Trumps lawless worst; it may reflect personal ambition, or mere hankering for as difficult a management challenge as one could imagine; or it may reflect a sneaking admiration for the boorish businessman who has successfully slapped around the politicians of left and right that many officers, and Marines in particular, despise as cowardly and corrupt. Kelly once handed a ceremonial saber to the President while unfunnily suggesting that he use it on the press. In April, hesaidthe following: If lawmakers do not like the laws theyve passed and we are charged to enforce, then they should have the courage and skill to change the laws. Otherwise they should shut up and support the men and women on the front lines. A less supine Congress might have noticed the discourtesy and reacted sharply to being told to shutup.
His occasionally contemptuous attitude towards the press and Congress, though, is only one reason why it is highly unlikely that Kelly will succeed. Trump will remain Trump, and the various denizens of the White House are unlikely to treat Kelly with much more deference than they treat one another. He will discover that he is no longer a general, or even a cabinet secretary, but a political functionaryneither more norless.
There was a reason why he spent 42 years on active duty rather than run for mayor of Boston. He probably already knows, but if not he will soon learn, that he will be as dispensable as his predecessor, that Trump hates any of his subordinates being too powerful or too visible. And worst of all, he will soon find himself wrestling with the moral corruption that being close to this man entails. You cannot work directly for Trump while adhering to a code of honesty, integrity, and lawfulness. Sooner or later Kelly will have to defend the White Houses jabber about fake news, alternative facts, and witch hunts. He will have to ascribe to Trump virtues that he does not possess, and deny the moral lapses and quite possibly the crimes that he hascommitted.
There is one further reason to find this appointment depressing. It contributes to the continuing decay of American civil-military relations. Those of us who were relieved to see James Mattis as secretary of defense, H. R. McMaster as national-security adviser, and Kelly himself as secretary of Homeland Security, felt that way partly out of appreciation for the virtues of all three men, but also, very largely, out of relief that their sanity might contain their bosss craziness. But it is inappropriate to have so many generals in policy-making positions; it is profoundly wrong to have a president regard the military as a constituency, and it is corrupting to have the Republican Party, such as it is, act as though generals have if not a monopoly then at least dominant market share in the qualities of executive ability and patriotism. It is unwise to have higher-level positions in the hands of officials who have openly expressed disdain for Congressnow a dangerously weak branch ofgovernment.
Trump, who has no idea how many articles there are in the Constitution, neither knows nor cares about any of the niceties of civil-military relations. To their credit, Kelly, Mattis, and McMaster have thought long and hard about these issues. But like any of us they have their individual limitations, and like any of us, their characters can be eroded by the whirlpool of moral and political corruption that is Donald Trump. The Marines live by a hard code, and John Kelly has endured tests of character more difficult than most of us can conceive. But his hardest tests lie ahead, and neither he nor anyone else can be sure that he will passthem.

‘All Systems Go’ for James Webb Telescope –"A Great Milestone for the Next Epoch in Space Exploration" – The Daily Galaxy (blog)
Posted: at 1:25 pm
Set to be launched in 2018 from Kourou, French Guiana, the JWST will embark on a journey to unravel the universes mysteries, "from discovering the first stars and galaxies" to "studying the atmospheres of alien planets around other stars."
NASA called, and the Webb telescope responded. NASAs James Webb Space Telescope recently completed its Ground Segment Test Number 1 (GSEG-1), for the first time confirming successful end-to-end communication between the telescope and its mission operations center.
The Deep Space Network comprises three ground stations located about 120 degrees apart on Earth one each in Canberra, Australia; Madrid, Spain; and Goldstone, California. This photo shows an antenna at the DSN site in California.
GSEG-1, which completed on June 20, tested all of the communications systems required to support the telescopes launch, commissioning and normal operations once it is in orbit. The test showed successful end-to-end communication between the Webb telescopes spacecraft bus, currently located at Northrop Grumman Aerospace Systems in Redondo Beach, California, and the telescopes mission operations center at the Space Telescope Science Institute in Baltimore.
Before this test, the flight operations team had only verified communication with the telescope piecemeal in several smaller tests that were not end-to-end.
During the test, the team sent the same command procedures to the telescope that will be sent during its nearly 1 million mile journey to its orbit at the second Lagrange point, known as L2. The team verified the configuration of the telescopes onboard computers and also received telemetry from the telescope, including science data and health monitoring data.
This is a great milestone not only for the telescope but for the industry team, who worked seamlessly together from coast to coast to successfully complete the GSEG-1, said Scott Willoughby, Northrop Grumman vice president and program manager for the Webb telescope. This test puts us one step closer in preparing for the Webb telescope for launch.
The ground segment test consisted of two parts the Space Network (SN) portion and the Deep Space Network (DSN) portion.
The eighthourlong SN portion of the test, completed May 24, tested all of the communications systems required during Webbs launch phase. During this portion of the test, the team successfully exchanged commands and telemetry with the telescope using NASAs Tracking and Data Relay Satellite (TDRS) network.
The 13hourlong DSN portion of the test, completed June 20, tested communications systems that will be used from the end of Webbs launch phase through the end of the mission. During this portion of the test, the team successfully exchanged commands, telemetry and ranging data with the telescope, as well as offloaded information from the telescopes data recorders.
DSN is our workhorse for the life of the mission, said Alan Johns. It got tested at every rate, every setting, and every possible permutation, and it worked just great.
The DSN comprises three ground stations, located about 120 longitudinal degrees apart from each other on Earth one each in Canberra, Australia; Madrid, Spain; and Goldstone, California. The placement of these guarantees the Webb telescope will be able to contact at least one station at all times, to remain in constant communication with Earth. For this test, the telescope communicated with a specially designed trailer that mimics these ground stations, rather than the ground stations themselves.
The success of the test did not catch Johns off guard. I felt pretty good that this test was going to be as successful as it turned out to be, Johns said. A lot of people put in a lot of hours, and the thoroughness that goes into checking every command parameter and every telemetry point paid off in the actual execution of the test.
Another communications test will take place at the telescopes planned launch site in Kourou, French Guiana, about a month before launch in late 2018. This test will demonstrate the expected connectivity with the telescope at first contact with it, which will occur approximately three-and-a-half minutes after launch.
NASAs James Webb Space Telescope is the worlds most advanced space observatory. This engineering marvel is designed to unravel some of the greatest mysteries of the universe, from discovering the first stars and galaxies that formed after the big bang to studying the atmospheres of planets around other stars. It is a joint project of NASA, ESA (the European Space Agency) and the Canadian Space Agency.

Nanotech Security has 57.5% upside, Haywood says – Cantech Letter
Posted: at 1:25 pm
With its third quarter results due on Thursday, Haywood analyst Pardeep Sangha thinks Nanotech Security (TSXV:NTS) will deliver its first-ever quarter of positive EBITDA.
On August 3, after market close, Nanotech will report its Q3, 2017 results. Sangha expects the company will post EBITDA of $100,000 on revenue of $2.8-million, a topline that would be up 145 per cent over the $1.2-million in revenue the company generated in the same period last year. Sanghas targets are in-line with the street consensus of $300,000 in EBITDA on revenue of $2.7-million.
Sangha says he thinks this will be a historic quarter for Nanotech.
We are expecting Nanotech to achieve its first quarter of positive EBITDA in Q3FY17 due to the increase in revenue and higher gross margins, the analyst says. He adds he will be on the companys conference call, listening for whether or not management reiterates its guidance to double revenue in fiscal 2017, on the progress of a $30-million development contract, and for sales pipeline activity, including a tax stamp opportunity in India.
In a research update to clients today, Sangha maintained his Buy rating and one-year price target of $2.00 on Nanotech Security, implying a return of 57.5 per cent at the time of publication.
Sangha thinks Nanotech will generate Adjusted EBITDA of negative $200,000 on revenue of $10.0-million in fiscal 2017. He expects those numbers will improve to EBITDA of positive $4.6-million on a topline of $21.5-million the following year.

Levels in Focus For NanoTech Gaming Inc (NTGL) – The Business Union
Posted: at 1:25 pm
Traders may be trying to figure out whether it is a good time to enter or exit a position in NanoTech Gaming Inc (NTGL). The Average Directional Index or ADX is a technical analysis indicator used to describe if a market is trending or not trending. The ADX alone measures trend strength but not direction. Using the ADX with the Plus Directional Indicator (+DI) and Minus Directional Indicator (-DI) may help determine the direction of the trend as well as the overall momentum. Many traders will use the ADX alongside other indicators in order to help spot proper trading entry/exit points. Currently, the 14-day ADX is 36.04. Generally speaking, an ADX value from 0-25 would indicate an absent or weak trend. A value of 25-50 would indicate a strong trend. A value of 50-75 would signal a very strong trend, and a value of 75-100 would indicate an extremely strong trend.
NanoTech Gaming Inc (NTGL) presently has a 14-day Commodity Channel Index (CCI) of -82.03. Typically, the CCI oscillates above and below a zero line. Normal oscillations tend to stay in the range of -100 to +100. A CCI reading of +100 may represent overbought conditions, while readings near -100 may indicate oversold territory. Although the CCI indicator was developed for commodities, it has become a popular tool for equity evaluation as well. The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and change of stock price movements. The RSI was developed by J. Welles Wilder, and it oscillates between 0 and 100. Generally, the RSI is considered to be oversold when it falls below 30 and overbought when it heads above 70. RSI can be used to detect general trends as well as finding divergences and failure swings. The 14-day RSI for NanoTech Gaming Inc (NTGL) is currently at 45.32, the 7-day stands at 41.51, and the 3-day is sitting at 23.50.
Taking a peek at some Moving Averages, the 200-day is at 0.01, and the 50-day is 0.01. Dedicated investors may be looking to employ another tool for doing technical stock analysis. The Williams Percent Range or Williams %R is a technical indicator that was designed to measure overbought and oversold market conditions. The Williams %R indicator helps show the relative situation of the current price close to the period being observed. NanoTech Gaming Inc (NTGL)s Williams Percent Range or 14 day Williams %R presently is at -61.11. In general, if the reading goes above -20, the stock may be considered to be overbought. Alternately, if the indicator goes under -80, this may show the stock as being oversold.
Investors may be trying to decide if the current market environment remains bullish. It can be extremely difficult to decide when to sell, especially when data seems positive and most signs are pointing higher. Jumping in to buy stocks on a pullback may seem like a good idea, but following specific sectors may become increasingly more important. Following long-term trends may help the investor see the bigger picture of what has been going on with a specific stock or sector. Deciding to sell a winner after a big run can be tempting, but knowing the underlying causes for the run may help identify if there may indeed be more room for gains. Avoiding common investing pitfalls may take many years to master, but it may end up determining long-term success.

Nootropic Effects of Psychedelic and Addictive Substances – Brain Blogger (blog)
Posted: at 1:23 pm
In my previous article on the subject of nootropics, I was writing about brain enhancing effects of some medicines and natural compounds. There is, however, a large number of nootropics that received little recognition from official science and remain rather poorly studied. There is a good reason for this too these compounds tend to be addictive or hallucinogenic. This article aims to cover what is known about the effects of these substances.
Nicotine
It is rather curious that nicotine, a well-known addictive component of tobacco smoke, was confirmed to have nootropic effect. The research into this property of nicotine was triggered by observations that ex-smokers tend to complain about the lack of concentration and general decline in various aspects of cognitive abilities. It turned out that nicotine does improve episodic and working memory, as well as attention. Nicotine doses delivered via patches had positive effects (improved performance in cognitive tests) in adults with mild cognitive disorders, as well as in healthy non-smokers.
Cannabis/marijuana and cognitive processes
People of artistic professions often claim that smoking pot helps creativity. There is scientific evidence to substantiate these claims. Cannabinoids seem to temporarily increase communication between the left and right hemispheres of the brain thus creating a state of hyperconnectivity and allowing a loose flow of associations. This may explain the heightened creativity individuals experience when using marijuana. Reports of positive benefits include improved mood, lower levels of anxiety, stress, and depression, improved focus and fewer distractions, improved reaction times, more creative thoughts, greater verbal fluency, and better calculative complexity. These effects are largely dose-dependent, and taking higher amounts may lead to the opposite effects including sluggishness, lack of focus, nervousness, and impaired memory formation and recall.
However, the negative long-term effects of cannabis on brain structure and function have been demonstrated beyond any reasonable doubt. In fact, cognitive decline associated with the use of cannabis is a serious medical problem, and lots of scientific research aims to gain insights into this problem and the potential approaches to reverse decline.
Grey area: Psychedelic drugs (LSD, mushrooms) in microdosing
Type psychedelics and microdosing in Google search, and you will be flooded with thousands of articles claiming that compounds like LSD and psilocybin (active component of magic mushroom) have almost miraculous effect on human cognitive abilities. It appears that many inventors, researchers and innovators use psychedelic compounds in very small doses, occasionally or regularly, to reach a state of enhanced consciousness, get into flow, and work more productively.
But here is a problem: not a single proper scientific publication supports these claims. There is a good reason for this: due to their well-known hallucinogenic properties and serious potential side effects, psychedelics like LSD are banned in most countries around the world. In fact, LSD was banned in the US and UK back in 1960s. This means that the only peer-reviewed published research that could inform on the actual measurable effects of psychedelics as a nootropic were done 50 years ago. The most commonly cited work (Harman, et. al. (1966) Psychedelic Agents in Creative Problem-Solving: A Pilot Study. Psychedelic Reports 19, 211-27.) was published in 1966. Although the findings reported in this publication are interesting, the quality of this work in terms of general organization, the use of suitable control subjects, and statistical power is hardly satisfactory.
The hallucinogenic properties of psychedelics are well documented. Microdosing of these compounds for enhancement of cognitive abilities, however, has not been investigated scientifically. This leave lots of space for imagination and conspiracy theories. There were repeated calls from the research community to lift the ban on research into psychedelics, but so far they seem to have fallen on deaf ears.
There are numerous evidences that psychedelics can be used to treat various psychiatric disorders. Some resent studies indicate that administration of psylobicin in moderate doses is not associated with any significant short-term or long-term risk. When it comes to cognitive enhancement, none of the available peer-reviewed scientific publications confirm or rule out such a phenomenon. One interesting resent publication claims that exposure to microdoses of psilocybin creates a state of hyperconnectivity in the brain. The findings from functional MRI experiments show:
that the structure of the brains functional patterns undergoes a dramatic change post-psilocybin, characterized by the appearance of many transient structures of low stability and of a small number of persistent ones that are not observed in the case of placebo. This means that the psychedelic state is associated with a less constrained and more intercommunicative mode of brain function, which is consistent with descriptions of the nature of consciousness in the psychedelic state.
In other words, the study indirectly points to the possibility of cognitive enhancement and creative stimulation under the influence of psychedelics. Nonetheless, a more definite confirmation of this phenomenon is yet to be published.
A word in defense of official science
People of a more adventurous nature tend to blame the science and medicine industry for slowness inrecognizing the benefits of smart drugs. But lets look at this problem from the perspective of researchers. Most drugs are safe, but from time to time people do experience serious side effects and even life-threatening complications. Nobody wants to be one of the unlucky few. If something goes wrong, youll have nobody but yourself to blame. Regulatory bodies can recommend any given substance for any particular use only when they have sufficient evidence thata) confirms its effectiveness andb) shows that its side effects are mild and manageable, and/or its benefits far exceed the potential complications associated with its use (i.e., the risk is worth taking).
Development of novel nootropics is hampered by research, validation, and regulatory challenges. The road from the research laboratory to FDA approval is difficult, long, and costly. Pharmacological enhancement of healthy populations is fraught with ethical and philosophical pushbacks. Therapeutic effects observed in cognitively impaired patients often contradict those in healthy populations. Even approved drugs have issues with side effects and large individual differences. The long-term effects of nootropics are typically unknown. Most importantly, there is still much to be learned about the cellular and molecular basis for the various aspects of cognition. Once they are better understood, pharmacologists will have much better ideas about the processes in the brain to target and how to do it.
It is easy to get carried away with the potential opportunities that nootropics might offer. But dont forget classical approaches: proper diet and exercise DO enhance brain functions. Many famous thinkers and creative people benefited from simple regular physical activities. Charles Dickens was spending several hours every day walking, sometimes for as much as 20 or 30 miles. Aristotle and Ludwig Van Beethoven are two other famous people who were known for their habit of wondering around while thinking. Physical activity pumps blood through your body and helps to deliver more oxygen to your brain. Regular exercise and healthy diet also keep your blood vessels healthy ensuring that this vital oxygenation is not reduced as you get older. Your normal lifestyle is responsible for your basic level of cognitive abilities. Smart drugs can be used to spike it up from time to time, but if the basic level is low, the spikes wont go that high anyway!
To sum it up, although an occasional joint may heighten your creativity, the regular use of cannabis is definitely not a good approach to enhance cognitive abilities. There is an acute lack of research on benefits (or absence of such) of psychedelics in cognitive enhancement. Virtually all online information on the benefits of psychedelics as cognitive enhancers are completely unsubstantiated by scientific evidence. Any positive or negative appraisals represent personal views of the articles authors rather than results of research studies. Your lifestyle influences you basic level of cognitive abilities dont ignore generally accepted good strategies.

Pimp my Brain: The Quest for Intelligence – TG Daily (blog)

The desire to tweak ourselves is embedded in nearly all of us. We try to tweak our appearance with our morning grooming and dressing rituals, we try to tweak our bodies with diets and exercise, and if that is not enough there is always plastic surgery to give nature a helping hand.
Tweaking our brain, on the other hand, is harder to realize and much harder to objectively quantify. When you go to the dentist and ask for a better smile, you can explain what you want, the dentist can visualize your expectations, and you can see and judge the result. But you cant go to a neurologist and say that you would like to be 10% smarter.
The brain is a complex and energy hungry organ, it represents around 2% of our body weight but uses 20% of our energy. When we talk about pimping our brain, we have to first decide what attribute we want to pimp, why we want to pimp it and then decide how, if at all possible, to pimp it.
There is a billion dollar industry built around supplements. It ranges from nootropics, that can help a student get a study edge, or enhance a fighter jet pilots combat abilities, to herbal based products, that promise a better memory or a better blood flow in our brains.
I had mentioned Modafinil, a popular nootropic, in a previous article. Apparently it is proven to have cognitive effects, like enhancing attention and concentration. If you search the internet there are a lot of first hand experiences of the drugs subjective effect on users; there are also studies about the measurable effect the drug has on our brains, so it is safe to say that it is not just a hype, but there are far too few studies on the long term effects to label the drug as harmless.
Prof. Con Stough, Professor of Cognitive Neuroscience and Psychology at Swinburne University, has been studying nootropics and their effects on the human brain for quite a while. In a Reddit AMA session, the professor discusses the effects, and side effects, of different drugs that he has studied. He confirms that there are measurable, positive cognitive effects from Modafinil, but he believes the enhanced ability to solve problems, is more a subjective feeling than an objective observation.
Interestingly he also admits to taking vitamin B6, B12 and antioxidants, Pycnogenol, as supplements. Insisting that he has not done any studies, only reviews, he is also convinced of the positive effects Bacopa and Ginseng, two popular plant-based supplements, have on our brains.
We have all heard it somewhere- The brain is like a muscle and can be trained.
A lot of us have been brought up believing that we are born with a limited number of brain cells, and with time, alcohol and stress, they will irreversibly die away, making us dumber by the day. That is not true, we constantly grow new brain cells, like all other cells, and taking your brain for a jog is not really a joke. Studies show that new muscles make new proteins that also stimulate the brain to grow.
Learning new motor skills, like juggling, or behavioral/ environmental changes, are known to encourage synaptogenesis. Adults with an increased number of synapses have a better cognitive functionality, and are less likely to suffer from neurodegeneration, compared to their peers with a lower synapses density.
What apparently does not help, is the sea of apps and computer programs that promise to improve your brain, in some way or the other, through regular training. One study
has shown that after six weeks training with diverse computer programs, there were measurable improvement in a number of benchmarking tests participants took before and after the training period, but it did not translate into an improvement of tasks that were not trained, even if they were cognitively similar. So you get better in what you are training but it doesnt mean that your brain will generally function better.
There are lots of methods to enhance your brain, some a little extreme and not yet recommendable, like implanting electrodes in your head and electrocuting your brain; and others more subtle, like association methods to help you remember things better. The question is: how much of what do you really need, and how do you measure intelligence? Is a bigot with a PhD. more intelligent, or a compassionate social worker with a high school diploma?
