Tale of Love and Illness Ends in Deaths
Tale of Love and Illness Ends in DeathsBy MATT FLEGENHEIMERPublished: March 30, 2012 His was a love story, Charles D. Snelling wrote — a tale of a shiftless dreamer and the woman who saved him, of the life they built over six decades and the disease that stood no chance of erasing it. By the end, he said, their time together had become a case study in reciprocity. “She took care of me in every possible way she could for 55 years,” Mr. Snelling wrote of his wife, Adrienne, months before the two were to celebrate their 61st wedding anniversary. “The last six years have been my turn, a... mais »
Brain & Ethics
How Does the Brain Secrete Morality?Pondering the neuroscience of moral platitudes, free will, and sacred values. Ronald Bailey | March 21, 2012 “The brain secretes thought as the liver secretes bile,” asserted 18th century French physiologist Pierre Cabanis. Last week, the Potomac Institute for Policy Studies convened a conference of neuroscientists and philosophers to ponder how our brains secrete thoughts about ethics and morality. The first presenter was neuroeconomist Gregory Berns from Emory University whose work peers into brains to see in which creases of gray matter those v... mais »
3D Brain Structure
The brain is wired in a 3D grid structure, landmark study findsMarch 30, 2012 (Vejam video da Science ao final) *[+]*[image: brainpathways1] Neighborhood structure of cerebral pathways. A curved sheet of interwoven orthogonal pathways (Credit: Van J. Wedeen, et al./Science) The brain appears to be wired in a rectangular 3D grid structure, suggests a new brain imaging study funded by the National Institutes of Health. “Far from being just a tangle of wires, the brain’s connections turn out to be more like ribbon cables — folding 2D sheets of parallel neuronal fibers that cross paths at... mais »
New Genetic Discovery
New layer of genetic information discoveredMarch 30, 2012 *[+]* The structure of a ribosome (credit: Dale Muzzey/UCSF) A hidden, never-before-recognized layer of information in the genetic code has been uncovered by a team of scientists at the University of California, San Francisco (UCSF) thanks to a technique developed at UCSF called ribosome profiling, which enables the measurement of gene activity inside living cells — including the speed with which proteins are made. By measuring the rate of protein production in bacteria, the team discovered that slight genetic alterations could... mais »

Billion of Planets
*Life on Billions of Planets? Could Be* By MICHAEL D. LEMONICK Friday, Mar. 30, 2012 This artist's impression shows a sunset seen from the super-Earth Gliese 667 Cc. "The Creator must have an inordinate fondness for beetles," the early 20th-century biologist J.B.S. Haldane once said. "He made so many of them." If Haldane had been an astronomer, he might have said the same about the nondescript red stars known as M-dwarfs. As the name implies, they're small, no more than half the size of our Sun at most. They're so dim that not a single one, not even the closest, is visible to the na... mais »

In the psychiatrist’s best-known previous books, *The Antidepressant Era* and *Let Them Eat Prozac,* Healy... mais »
Diferenças de Gênero
Jornal Mente Corpo Março Diferenças de Gênero - Aloyzio Achutti As diferenças de gênero sempre despertam curiosidade, provavelmente, desde a descoberta de ostensivas diferenças anatômicas: a existência de apêndices externos em uns, inexistentes em outros. Se estas características não nos fossem desde logo escondidas, não haveria necessidade de colocar cores distintivas em fitinhas no cabelo, roupinhas, sapatinhos: cor de rosa uns; outros, azuis. 19/03/2012 Saiba mais. ------------------------------

Medicine & Humanity
"US health system reform--what's missing?" Humanity POSTED MAR 25, 2012 AT 05:44 PM, EDT BY MELISSA WALTON-SHIRLEY I don't know the identity of the physician that stood at the microphone at the end of this presentation, but he hit the nail on the head. "Healthcare is a basic human right," he said; which raises the question, "If the right to healthcare is so basic, why is it so problematic?" When there's trouble in any country, it most usually has to do with the age-old struggle to balance the supply of cash with the demand for services, but that is a woefully inadequate summation.

All the Digital Data In the World Is Equivalent to One Human Brain Supercomputer An IBM Blue Gene/P supercomputer rack. Wikimedia Commons By Rebecca BoylePosted 02.11.2011 at 6:05 pm13 Comments If you could put all the data in the world onto CDs and stack them up, the pile would stretch from the Earth to beyond the moon, according to a new study. The world’s technological infrastructure has a staggering capacity to store and process information, reaching 295 exabytes in 2007, a reflection of the world’s almost complete transition into the digital realm. That's a number with 20 zeroes... mais »

Study: Why Flu Hits Some People Harder than Others By ALEXANDRA SIFFERLIN | @acsifferlin | March 26, 2012 | + * * [image: Tom Grill / Getty Images] TOM GRILL / GETTY IMAGES During the 2009-10 H1N1 or “swine flu” pandemic, the same virus that caused mild coughing and sneezing in some patients proved fatal for others.
