O gene altruísta *Guerra acadêmica sobre a evolução da ética* *RESUMO* O biólogo americano E. O. Wilson causa celeuma ao argumentar, em livro, em favor da "seleção de grupo", forma de seleção natural que afeta grupos, e não indivíduos. Ao minimizar importância da tradicional "seleção de parentesco", Wilson propõe uma nova visão sobre a trajetória evolutiva de insetos e humanos. *REINALDO JOSÉ LOPES* *ILUSTRAÇÕES ANDRÉ FARKAS* *EDWARD OSBORNE* Wilson, 82, nunca foi um sujeito modesto, embora quase todos os que o conhecem façam questão de louvar a gentileza um tanto antiquada do biólo... mais »

A 50 gigapixel camera five times better than 20/20 human visionJune 21, 2012 Traffic circle captured using AWARE-2 (credit: Duke University Imaging and Spectroscopy Program) By synchronizing 98 tiny cameras in a single device, engineers from Duke University and the University of Arizona have created a prototype camera that could capture up to 50 gigapixels of data (50,000 megapixels) and images with unprecedented detail. The AWARE-2 camera’s resolution is five times better than 20/20 human vision over a 120 degree horizontal field. By comparison, most consumer cameras are capable of t... mais »

Researchers find gold nanoparticles capable of ‘unzipping’ DNAJune 21, 2012 As the gold nanoparticles cluster together, they pull the strands of DNA apart (credit: NCSU) New research from North Carolina State University finds that gold nanoparticles with a slight positive charge work collectively to unravel DNA’s double helix — a finding with ramifications for gene therapy research and the emerging field of DNA-based electronics. The research team introduced gold nanoparticles, approximately 1.5 nanometers in diameter, into a solution containing double-stranded DNA. The nanoparticles... mais »

Earth: History

Aloyzio AchuttiemAMICOR - 11 horas atrás
The History of EarthEarth is believed to be 4.5 to 5 billion years old and was probably formed along with the rest of the solar system when a dusty nebula coalesced into distinct planetary bodies. Since its creation, Earth has endured numerous transformations and catastrophes, geological and biological alike. Though life on the planet arose roughly 3.5 billion years ago, humans appeared only relatively recently. What planet may have long ago collided with Earth, ejecting enough material into space to form the Moon? More...

Novel Protein : Alzheimer's Vaccine

Aloyzio AchuttiemAMICOR - 1 dia atrás
June 21, 2012 — A neuronal protein may offer a potential target for immunization against Alzheimer's disease (AD), new research suggests. According to investigators from the University of Zurich, ankyrin G (ankG) may represent a novel target for AD immunotherapy. "We showed that a pathological extracellular deposition of the neuronal protein ankG evokes the production of antibodies in patients with AD, which may reduce the level of beta-amyloid and its related neurological disease," Antonella Chadha Santuccione, MD, of the Division of Psychiatry Research, University of Zurich, in Swi... mais »

I want to know where love is: Research develops first brain map of love and desire June 20, 2012 in Psychology & Psychiatry *Thanks to modern science, we know that love lives in the brain, not in the heart. But where in the brain is it – and is it in the same place as sexual desire? A recent international study is the first to draw an exact map of these intimately linked feelings.* Somewhat surprisingly, this area of the striatum is also the part of the brain that associated with drug addiction. Pfaus explains there is good reason for this. "Love is actually a habit that is formed fr... mais »

The Makings of Our Earliest MemoriesBy PERRI KLASS, M.D. Joyce Hesselberth Like many other pediatricians, I do not wear a white coat. Many of us believe that babies and small children suffer from a special form of “white coat syndrome,” that mix of trepidation and anxiety that some adults experience — to the point of high blood pressure — in a medical setting. The pediatric version is easy to diagnose: Doctor in white coat walks into room, kid starts to cry. I worry that a child like this has recalled shots or an unpleasant ear check and has connected that memory to a particular gar...mais »
