Memory
A memory of shifting sandsby vaughanbell *The New York Review of Books* has a reflective piece by Oliver Sacks on the swirling mists of memory and how false recall has affected authors and artists throughout history. [Science] is startling to realize that some of our most cherished memories may never have happened—or may have happened to someone else. I suspect that many of my enthusiasms and impulses, which seem entirely my own, have arisen from others’ suggestions, which have powerfully influenced me, consciously or unconsciously, and then been forgotten/..../ http://www.nybooks.c... mais »
preventing cognitive decline
Blocking this molecule in the brain could prevent age-related cognitive declineFebruary 8, 2013 Blocking a specific molecule in the brain that creates age-related cognitive decline (left) restores neurogenesis (neuron growth) and neuron branching (right) (credit: D. R. M. Seib et al./Cell Stem Cell) Researchers have discovered a molecule that accumulates with age and inhibits the formation of new neurons. The finding might help scientists design therapies to prevent age-related cognitive decline. The investigators identified the molecule, called Dickkopf-1 or Dkk1, in the brains of a... mais »
Heart variability and art appreciation
Wolfgang Tschacher, psychologist, on how we appreciate art By Christie Nicholson | February 8, 2013, 4:39 AM PST 0Comments more + - - - - - - - We might think art experts and artists have a leg up on art appreciation that rewards them with a deeper enjoyment of art. But it turns out art literacy makes little difference in how much one appreciates art works. This was one finding from a recent study done with nearly 600 museum visitors that ranged from art experts to regular members of the public who may have only had limited engagement with art.

Fogo
O que é o fogo, afinal? Por Guilherme de Souza em 5.02.2013 as 10:46 Para Aristóteles, era um dos quatro elementos fundamentais que formavam o mundo. Para aqueles que acreditavam na mitologia grega, era um artefato dos deuses, roubado pelo titã Prometeu e dado à humanidade.Uma das descobertas mais importantes da história da humanidade, o fogo pode ser tanto fonte de vida como de morte e destruição. Mas, afinal, o que é fogo?/.../

Here is one possible answer. *George Dvorsky* The more we learn about the universe, the more we discover just how diverse all its planets, stars, nebulae and unexplained chunks of matter really are. So what is all this matter doing in our universe, other than just floating in space? Well, it just so happens that there is a theory that gives a kind of *raiso*

Being sedentary for long periods of time, su... mais »
amyloid protein
Study Shows Alzheimer’s Protein May Not Spread Like a Virus By Alexandra SifferlinFeb. 05, 2013 Scientists believe that amyloid protein plays a role in Alzheimer’s but are still trying to explain how. One of the hallmarks of Alzheimer's disease, which is characterized by memory loss and dementia, is a protein called amyloid. In patients who die of the disease, sticky plaques of the protein are found in the brain at autopsy, although not all people with amyloid deposits develop Alzheimer’s. But why does the protein start to gum up the delicate network of nerves in the brain? Some rec... mais »

coal burning
The Scariest Environmental Fact in the World By Bryan WalshJan. 29, 201352 Comments - See this sobering graph from the U.S. Energy Information Administration (EIA): As the data show, China is now burning almost as much coal as the rest of the world — combined. And despite impressive support from Beijing for renewable energy and a dawning understanding about the dangers of air pollution, coal use in China is poised to continue rising, if slower than it has in recent years. That’s deadly for the Chinese people — see the truly horrific air pollution in Beijing this past month ... mais »
