Energy and Brain
Why does the brain use so much energy? NEUROSCIENCE20 JANUARY 16 by EMILY REYNOLDS We know more about what the brain does when it's active than we do when it's at rest. It makes sense -- muchneuroscientific research has looked to understand particular (and active) processes. James Kozloski, a researcher at IBM, has investigated what the brain does when it's resting -- what he calls 'the Grand Loop'. "The brain consumes a great amount of energy doing nothing. It's a great mystery of neuroscience," Kozloski told PopSci. He argued that around 90 percent of the energy used by the brain... mais »

Sometimes your train is late; sometimes it rains when it’s not supposed to; the drugstore doesn’t have the brand of dental floss you like. Boundaries are violated and rules are ignored. The green spinach on your plate touches the white chicken, and someone has bought your boxer shorts from J. C. Penney instead of from Kmart. People are hard to figure out. S... mais »
Religion
Religion May Be Part of Our EvolutionBelieve it, or not. A new book, *God Is Watching You*, by social scientist Dominic Johnson, explores the benefits of religion. While belief systems are often blamed for worldly woes, researchers have measured their behavioral benefits and found that fear of divine retribution is a powerful motivator for being good. The findings support the author's theory that religion is an evolutionary blessing. Atheism can use science as a "gospel of enlightenment," but Johnson says it's no less flawed thanreligion - and what folks really need is a bit of fai... mais »

How to rewire the brain with artificial axons to replace damaged pathways Research promises to one day restore functionality for patients with damaged axons resulting from brain injury or disease January 21, 2016 [image: axon extensions ft] Penn State scientists have grown improved artificial transplantable artificial axons (brain pathways) in the lab. The new “micro-tissue engineered neural networks” (micro-TENNS) replace broken axon pathways when implanted in the brains of rats. (Neurons are connected by long fibrous projections known as axons. When these connections are damaged, the... mais »
Over 100
[image: aging 3826026924 d6ea06baab o] Americans Are Making It to 100 Like Never Before They’re living to a ripe old age. The rate of Americans making it past their 100th birthday has jumped by 43 percent in a decade. Death rates for centenarian women dropped 14 percent, and 20 percent for men, between 2008 and 2014, which means that folks with the greatest longevity are also sticking around longer. But their chances of developing Alzheimer’s also increased — from 3.8 to 8.5 percent — making the brain disease the second leading cause of death, after heart disease, for those over 10... mais »
Healthy Society
The secrets of a healthy society Richard Horton[image: email] © 2016 Elsevier Ltd. All rights reserved. - It has become something of a tired cliché to talk about a National Disease Service. The idea that doctors don't do health but only disease is an easy hit, a sharp elbow in the side of a privileged profession. As anyone who has actually seen a doctor at work knows, it isn't true. Anyway, it would be foolish to think that the health of an individual should be left to doctors alone. And if personal health is beyond the reach of the doctor, a healthy society is certainly bey... mais »

All study participants had the APOE ε4 gene but were free from cognitive impairment when the investigation began. They ranged in age from 69 to 80 years old; 341 were white, 329 were black.

Omega 3 Levels Affect Whether B Vitamins Can Slow Brain's Decline By News Staff | January 20th 2016 06:20 AM | While research has already established that B vitamin supplements can help slow mental decline in older people with memory problems, an international team have now found that having higher levels of Omega-3 fatty acids in your body could boost the B vitamins' effect. The team, from the Universities of Cape Town, Oslo, Oxford and the UAE, studied more than 250 people with mild cognitive impairment (MCI) in Oxford.

Like Human Civilization? Thank Our Evil Side By News Staff | November 25th 2015 07:33 AM | The speed and character of human dispersals changed significantly around 100,000 years ago, and our dark side deserves a thanksgiving for that; a new paper suggests that betrayals of trust were the missing link in understanding the rapid spread of our species around the world. Early species of hominin were limited in distribution to specific environments such as grasslands and open woodland. The expansion of Homo erectus out of Africa into Asia around 1.6 million years ago appears to have be... mais »

A descoberta pode ser a evidência mais precoce de conflito humano já registrada pela ciência./.../
