The Human Anatomy, Animated With 3-D Technology The answer is yes at the New York University School of Medicine, which is using 3-D technology to update a rite of passage for would-be doctors: anatomy class. In a basement lab at NYU Langone Medical Center in Manhattan last month, students in scrubs and surgical gloves hovered over cadavers on gurneys, preparing, as would-be doctors have for centuries, to separate rib cages and examine organs. But the dead are imperfect stand-ins for the living. Death — and embalming fluid — take a toll. Will Potter: The secret US prisons you've never heard of before Father Daniel Berrigan once said that "writing about prisonersis a little like writing about the dead."I think what he meant is that we treat prisoners as ghosts.They're unseen and unheard.It's easy to simply ignore themand it's even easier when the government goes to great lengths to keep them hidden. As a journalist, I think these storiesof what people in power do when no one is watching,are precisely the stories that we need to tell.That's why I began investigatingthe most secretive and experimental prison units in the United States,for so-called "second-tier" terrorists.The government calls these units Communications Management Units or CMUs.Prisoners and guards call them "Little Guantanamo."They are islands unto themselves.But unlike Gitmo they exist right here, at home,floating within larger federal prisons. There's an estimated 60 to 70 prisoners here,and they're overwhelmingly Muslim.They include people like Dr. So, why was he moved?

The Science of "Chunking," Working Memory, and How Pattern Recognition Fuels Creativity by Maria Popova “Generating interesting connections between disparate subjects is what makes art so fascinating to create and to view… We are forced to contemplate a new, higher pattern that binds lower ones together.” It seems to be the season for fascinating meditations on consciousness, exploring such questions as what happens while we sleep, how complex cognition evolved, and why the world exists. Long-term potentiation Long-term potentiation (LTP) is a persistent increase in synaptic strength following high-frequency stimulation of a chemical synapse. Studies of LTP are often carried out in slices of the hippocampus, an important organ for learning and memory. In such studies, electrical recordings are made from cells and plotted in a graph such as this one.

The Brain Needs Downs to Have Ups Four neurochemicals cause happiness : endorphins, dopamine , oxytocin and serotonin. Each evolved to do a different job. When you know what the job is, you know why your happy chemicals can't be on all the time. 1. The Decline Effect Is Stupid Is there something wrong with the scientific method? asks Jonah Lehrer in The New Yorker. The premise of the article is a well known phenomenon called the Decline Effect. As described in the story, that's when exciting new results, initially robust, seem not to pan out over time.

Princeton Engineering Anomalies Research Lab The Princeton Engineering Anomalies Research (PEAR) program was established at Princeton University in 1979 by Robert G. Jahn. Despite the name, the project had little to do with engineering but rather was dedicated to the study of parapsychology.[1] PEAR's primary purpose was to engage in parapsychological exercises purporting to examine telekinesis and remote viewing.[2] The program had a strained relationship with Princeton, and was considered "an embarrassment to science.

The New York Times > New York Region > 'Excuse Me. May I Have Your Seat?' Published: September 14, 2004 hirty years ago, they were wide-eyed, first-year graduate students, ordered by their iconoclastic professor, Dr. Stanley Milgram, to venture into the New York City subway to conduct an unusual experiment. Their assignment: to board a crowded train and ask someone for a seat. Then do it again. Researchers Say: Fill Your Bladder To Clear Your Mind Before you make any life-altering decisions in the future, you may want to guzzle a few liters of water. At least, that’s according to new research that found that people with water-filled bladders are better at making decisions about their future—a finding that not only counters common sense, but also flies in the face of past psychological consensus. Lead author of the study published in Psychological Science, Mirjam Tuk, a scientist at the Netherland’s University of Twente, landed upon this unique research topic after she drank too much coffee during a lengthy lecture. As the coffee made its way to her bladder, she asked herself a question: “What happens when people experience higher levels of bladder control?”

Two planets found sharing one orbit - space - 24 February 2011 Update on 5 March: Lead researcher Jack Lissauer says: "Further study of the light curve of this target produced an alternative interpretation wherein one of the co-orbital candidates (KOI 730.03) has a period that is twice what we originally estimated. We think that this new interpretation, without co-orbital candidates, is more likely to be correct. We will continue to acquire Kepler data and ground-based observations ... so we can reach a better understanding of this interesting, multi-resonant, system."

Charles Limb studies the neurology of music and creativity. In this TED talk he shows fMRI contrast maps of his experiments with people playing memorised music versus people improvising music. He shows that the activity in the lateral prefrontal cortex, which is involved in self-monitoring, lowers. And activity in the medial prefrontal cortex goes up. Next he shows what happens when musicians improvise together. The language areas, i.e. Broca's area, became more active. The third experiment is about memorised rap versus freestyle rap: then you see activity in the visual areas and motor coordination areas, so lots of brains areas aree active in creative rapping. by kaspervandenberg Jan 9
