AD transmition??
Medscape Medical News > Neurology Is Alzheimer's Transmittable? Sue Hughes September 11, 2015 The possibility that Alzheimer's disease could be transmitted by surgical procedures has been raised by researchers studying prion diseases. They have reported an autopsy study of eight young or middle-aged patients with prion disease (linked to treatment with cadaver-derived human growth hormone) in which the Alzheimer protein amyloid β was also detected. They note that such pathology is rare in this age range and none of the patients had mutations associated with early-onset Alzheimer's. "Ou... mais »
Genoma Editing
Why human genome editing research is essential September 10, 2015 [image: Genome with mutation (credit: NIH)] “Restricting research ... is premature and dangerous" Research involving editing the human genome, including research with human embryos, is essential to gain basic understanding of biology and germ cells and should be permitted, according to one of the first global meetings to debate the controversial new techniques. The bold statement was published today (Thursday, Sept. 10) by the Hinxton Group, a global network of … more…

Reading speed
Using Technology to Break the Speed Barrier of Reading New research suggests that one of humanity’s most important inventions can be improved By Matthew H. Schneps | September 8, 2015 [image: books] While cramming symbols tightly together may have seemed like a brilliant way to save on parchment, scientists are now beginning to understand that this design decision runs afoul of the way the brain processes visual information. *Credit: Antonis Liokouras ©iStock.com* I grew up in a tiny New York City apartment, packed in alongside our four cats and my father’s immense personal library ... mais »

Neoliberal Ebola
*Recomendado por AMICOR Roger dos Santos Rosa*Neoliberal Ebola: The Agroeconomic Origins of the Ebola Outbreak July 27, 2015 (Un)Sustainable Farming, Commentaries, Health 1 Comment by Rob Wallace The notion of a neoliberal Ebola is so beyond the pale as to send leading lights in ecology and health into apoplectic fits. Here’s one of bestseller David Quammen’s five tweets denouncing my hypothesis that neoliberalism drove the emergence of Ebola in West Africa. I’m an “addled guy” whose “loopy [blog] post” and “confused nonsense” Quammen hopes “doesn’t mislead credulous people.” Scientif... mais »

Trillions of viruses inhabit each of our bodies, far outnumbering both our cells and the bacterial cells our bodies host. Collectively, these viruses are referred to as our "virome," and they impact the way our genome expresses itself and evolves. Whereas in the past, scientists thought of our genes (referred to collectively as our genome) as being the primary determinant of our develop... mais »

Prion
A Red Flag for a Neurodegenerative Disease That May Be Transmissible Animal experiments show how a just-discovered prion triggers a rare Parkinson’s-like disease ----------------------------- Much evidence now supports the idea that many neurodegenerative diseases share this core mechanism of self-propagating proteins that accumulate and ultimately kill cells. Similar findings have been reported for amyloid beta, the protein that accumulates in Alzheimer's disease, although typically in terms of increasing damage, rather than transmission. “I think Prusiner's concept is valid—it's ju... mais »

Pets
What Your Pet Reveals about You Is there a typical cat person or snake owner? The jury is still out By Karen Schrock Simring | Sep 1, 2015 Most of us think our pets say a lot about who we are. Why else would we proudly proclaim our loyalty on T-shirts and in online profile pictures? Yet few scientists have rigorously investigated whether our choice of pet reveals anything about our personality, beliefs or lifestyle. *Scientific American MIND* rounded up the smattering of available research and highlighted some of the more interesting findings in the infographic that starts below and c... mais »
eudaimonic well-being
The Creative Life and Well-Being By Scott Barry Kaufman | March 16, 2015 | The Creative Life is full of new possibilities, discoveries, exploration, experimentation, self-expression, and invention. It's a habit, a way of being, a style of existing. But is the Creative Life full of well-being? *Depends on how you define well-being.* In recent years, psychologists have taken a deeper look at well-being. The traditional approach to well-being focuses on hedonic pleasures and positive emotions. However, while positive emotions often accompany happiness, the mere experience of positive em... mais »

13.2 billion years old galaxy
[image: a galaxy] Scientists Discover Oldest, Farthest Known Galaxy It’s not quite as old as the universe. But galaxy EGS8p7, according to Caltech astrophysicists, is 13.2 billion years old — compared to the universe’s 13.8 billion — and smashes expectations by having what’s known as a Lyman-alpha line, a spectral signature caused by superhot hydrogen gas, usually only present in very young galaxies that are churning out stars. The researchers plan to investigate further and hope the galaxy’s unique spectrographic signature will help inform our understanding of the universe’s infancy... mais »
