POPSThe Behavioral Revolution it’s just that most of the action takes place below the level of awareness. Looking at and perceiving the world is an active process of meaning-making that shapes and biases the rest of the decision-making chain. This meltdown is not just a financial event, but also a cultural one. It’s a big, whopping reminder that the human mind is continually trying to perceive things that aren’t true, and not perceiving them takes enormous effort. Very interesting, read it!

POPSDoubt in FDA View Of BPA BPA, first synthesized in 1891, is used to harden plastics, and it appears in everything from baby bottles to sunglasses. Studies suggest BPA may be associated with a variety of problems, including Type-2 diabetes, prostate cancer, genital defects in men, early onset of puberty in women and behavioral problems. There much more around. Triclosan in fluid soaps, shampoos and toothpaste, 90% positive tests for pesticides in random urine tests, transfat oils... Looks like weapons of mass destruction.:(

POPS Brain's Hub of Fear Found The results of the study, funded by the National Institutes of Health, the National Science Foundation, Burroughs Wellcome Fund, the Center for Behavioral Neuroscience and the Yerkes Center, are detailed in the October issue of the journal Nature Neuroscience. The genetically engineered virus was injected into the amygdala of the mice by Emory graduate student Kimberly Maguschak. The amygdala is a part of the brain thought to be important for forming memories of emotionally charged events. "We found that after beta-catenin is taken out, the mice can still learn to fear the shocks," Maguschak said. "But two days later, their fear doesn't seem to be retained because they spend half as much time freezing in response to the tone." So it appears that beta-catenin is turned on in the amygdala to help in signaling during the learning process, Maguschak said.

POPSNurture affects physiology A study at the University of Minnesota is finding that nurture in early childhood really does matter to the physical structure of the brain.

POPSConfidence game - The science of Trustworthiness Researchers have discovered that surprisingly small factors - where we meet someone, whether their posture mimics ours, even the slope of their eyebrows or the thickness of their chin - can matter as much or more than what they say about themselves. We size up someone's trustworthiness within milliseconds of meeting them, and while we can revise our first impression, there are powerful psychological tendencies that often prevent us from doing so - tendencies that apply even more strongly if we've grown close.

POPSYour brain lies to you This phenomenon, known as source amnesia, can also lead people to forget whether a statement is true. Even when a lie is presented with a disclaimer, people often later remember it as true. With time, this misremembering gets worse. A false statement from a noncredible source that is at first not believed can gain credibility during the months it takes to reprocess memories from short-term hippocampal storage to longer-term cortical storage. As the source is forgotten, the message and its implications gain strength.

POPSDNA Study Unlocks Mystery To Diverse Traits In Dogs Dogs originally derived from the wolf more than 15,000 years ago -- a blink of the eye in evolutionary terms. Selective breeding produced dogs with physical and behavioral traits that were well suited to the needs or desires of their human owners, such as herding or hunting ability, coat color and body and skull shape and size. This resulted in the massive variance seen among the more than 350 distinct breeds that make up today's dog population. Until now, the genetic drivers of this diversity have intrigued scientists who have been trying to explain how and why the difference in physical and behavioral traits in dogs changed so rapidly from its wolf origins.

POPS10 Ways We Get the Odds Wrong And the two last ones: IX. We Love Sunlight But Fear Nuclear Power Why "natural" risks are easier to accept. X. We Should Fear Fear Itself Why worrying about risk is itself risky. Though the odds of dying in a terror attack like 9/11 or contracting Ebola are infinitesimal, the effects of chronic stress caused by constant fear are significant. Studies have found that the more people were exposed to media portrayals of the 2001 attacks, the more anxious and depressed they were. Chronically elevated stress harms our physiology, says Ropeik. "It interferes with the formation of bone, lowers immune response, increases the likelihood of clinical depression and diabetes, impairs our memory and our fertility, and contributes to long-term cardiovascular damage and high blood pressure."

POPSWhy the Brain Follows the Rules
Not surprisingly, the threat of punishment made people act more fairly. In the “punishment threat condition” people split the money close to equally. However, when Person B had no recourse, the people given the money acted very differently and gave away, on average, less than 10 percent of the money. When the researchers looked at the brain activity of people playing this simple game, they found a consistent pattern. One region in the frontal lobes, the orbitofrontal cortex, seemed to be responsible for evaluating the potential for punishment. In other words, it figured out whether or not violating the social norm would get us in trouble. A second brain region, the dorsolateral prefrontal cortex, was responsible for inhibiting the natural tendency to keep most of the money (this would be the greedy thing to do) if this action might lead to future punishment. Interestingly, these brain areas only were activated when the threat of punishment came from a real person, and not a compute

POPSThe Nearest Thing to Mind Reading “A person can put up a good face and avoid disclosing different types of information,” he added. “You would think depressed people party less, talk less, laugh less and interact less. But the students who reported having the most depressive symptoms did those things as much as anyone else.” The researchers uncovered a few things: Stream of consciousness writing often speaks more loudly about private personality traits than do public forms of expression and those who read personal narratives written by other people can most often come up with an accurate judgment of that person’s character.

POPSWatch UC Berkeley Lectures (entire courses) Online, Free, Now. from anthropology to electrical engineering to geography to history to english to math to physics - Just about every class Berkeley offers. There's a drop down list at the top right, select a semester to see what classes are available. Each one has new classes. Personally I recommend Professor Muller's "Descriptive Introduction to Physics". He's a brilliant physicist and a great teacher. After that I'd recommend the "Modern Physics" class. You watch all the lectures as if you were sitting inside the classroom. The best part is, it's all legal! AND if you wanted a degree, you could watch all the lectures, study the coursenotes (also available online for free) - and then challenge the course once you know the material. pass the test and basically get a free degree. haha
