Why Are There No Biological Tests in Psychiatry? - Scientific American Blog NetworkThe problem of teasing out heterogeneous clinical presentations in psychiatry is compounded by the fact that they also have heterogeneous underlying mechanisms. There will not be one pathway to schizophrenia; there may be dozens, perhaps hundreds. Biological tests that appear to be associated with schizophrenia are never useful for making the diagnosis because they always show more variability within the category than between categories. And seemingly intriguing findings usually don't replicate.
Why Abstract Art Stirs Creativity in Our Brains - Facts So Romantic - Nautilus“Creativity is for amateurs. We go out there and we solve problems. We set tasks for ourselves and we solve them.” I think the similarities are really becoming quite obvious. Certainly in the abstract expressionists—the New York group—they all ended up doing very different things when they started doing it, and they did it step-by-step as they moved from figuration to abstraction, becoming progressively more abstract in distinctively different ways.
100 billion neurons, unsourcedShe then returned to her alma mater to train young scientists in communication—with an allowance to pursue research if she were so inclined. She was inspired to do so by the pervasive myths about the brain she kept encountering, such as that we use only 10 percent of our capacity. Moreover, none of the distinguished neuroscientists she asked could tell her the source for the claim that there were 100 billion neurons in the brain, which they all believed.
Characterizing a psychiatric symptom dimension related to deficits in goal-directed control | eLifeProminent theories suggest that compulsive behaviors, characteristic of obsessive-compulsive disorder and addiction, are driven by shared deficits in goal-directed control, which confers vulnerability for developing rigid habits. However, recent studies have shown that deficient goal-directed control accompanies several disorders, including those without an obvious compulsive element.
How big was that quakeA thirty-second earthquake generally has a magnitude in the mid-sevens. A minute-long quake is in the high sevens, a two-minute quake has entered the eights, and a three-minute quake is in the high eights. By four minutes, an earthquake has hit magnitude 9.0.
"The Dress" is the perfect mirror for the subjective, fractured InternetThe fact that a single image could polarize the entire Internet into two aggressive camps is, let’s face it, just another Thursday. But for the past half-day, people across social media have been arguing about whether a picture depicts a perfectly nice bodycon dress as blue with black lace fringe or white with gold lace fringe. And neither side will budge. This fight is about more than just social media—it’s about primal biology and the way human eyes and brains have evolved to see color in a sunlit world.
Certainly for artists of all stripes, the unknown, the idea or the form or the tale that has not yet arrived, is what must be found. It is the job of artists to open doors and invite in prophesies, the unknown, the unfamiliar; it’s where their work comes from, although its arrival signals the beginning of the long disciplined process of making it their own. Scientists too, as J. Robert Oppenheimer once remarked, “live always at the ‘edge of mystery’ – the boundary of the unknown.” But they transform the unknown into the known, haul it in like fishermen; artists get you out into that dark sea.
Critics have pointed out that Dr. Keys violated several basic scientific norms in his study. For one, he didn't choose countries randomly but instead selected only those likely to prove his beliefs, including Yugoslavia, Finland and Italy. Excluded were France, land of the famously healthy omelet eater, as well as other countries where people consumed a lot of fat yet didn't suffer from high rates of heart disease, such as Switzerland, Sweden and West Germany. The study's star subjects—upon whom much of our current understanding of the Mediterranean diet is based—were peasants from Crete, islanders who tilled their fields well into old age and who appeared to eat very little meat or cheese. As it turns out, Dr. Keys visited Crete during an unrepresentative period of extreme hardship after World War II. Furthermore, he made the mistake of measuring the islanders' diet partly during Lent, when they were forgoing meat and cheese. Dr. Keys therefore undercounted their consumption of saturated fat. Also, due to problems with the surveys, he ended up relying on data from just a few dozen men—far from the representative sample of 655 that he had initially selected. These flaws weren't revealed until much later, in a 2002 paper by scientists investigating the work on Crete—but by then, the misimpression left by his erroneous data had become international dogma.
“The mentality of fission is that there is a systematic process—you define your loads, your criteria, and then you produce a design,” Chiocchio told me. “At the beginning, at ITER, sometimes I would ask my boss, ‘Can you tell me what the main requirements are for this component?’ And he would say, ‘What are you talking about? Try to find a solution.’ It was a bit more of a, let’s say, creative engineering environment.”
In the winter of 1976-77, they point out, the temperature in Chicago stayed below freezing for 43 days straight, and in 1985 the city had a below-freezing stretch of 40 days. The longest stretch so far this winter was 11 days. Similarly, New York’s longest stretch below freezing this year has been six days, less than half as long as the freezing periods in the 1970s.Perhaps this is the real reason everyone is panicking about the cold: Winters have become so mild over the past 20 to 30 years that a blast of Arctic air feels extraordinary. “If you were 10 years old when this last happened and now you’re 40, that’s quite a chunk of your life,” Mr. Henson said.
