First-ever human head transplant is now possible, says neuroscientist

First-ever human head transplant is now possible, says neuroscientist
Promotional posters for the new Everest movie recently appeared in New York City subway stations, and these days I travel to and from work with a strange lump in my throat. Everest, which opens in wide release in the US today (Sept. 25), is based on the true story of how eight people died in a storm on the world’s tallest mountain in 1996. It’s the same story that Jon Krakauer told in his bestselling book Into Thin Air. It was, until last year, the most deadly accident in Mount Everest’s history. Then on April 18, 2014, an ice release killed 16 climbers on the mountain. I was there, and my feelings about it are still a mess of contradictions. But when I watched the Everest trailer online a few weeks ago, I couldn’t stop shaking. I fretted about writing this article. But I’m still going to tell you all about it. I started reading books about mountaineering in grade school, and in college I developed an academic interest in the Himalayas. I was mostly worried about altitude sickness. Related:  ScienceArchive

Space-Time Loops May Explain Black Holes Physics cannot describe what happens inside a black hole. There, current theories break down, and general relativity collides with quantum mechanics, creating what's called a singularity, or a point at whichthe equations spit out infinities. But some advanced physics theories are trying to bridge the gap between general relativity and quantum mechanics, tounderstand what's truly going on inside the densest objects in the universe. Recently, scientists applied a theory called loop quantum gravity to the case of black holes, and found that inside these objects, space and time may be extremely curved, but that gravity there is not infinite, as general relativity predicts. This was the first time scientists have applied the full loop quantum gravity theory to black holes, and the results were encouraging, researchers said. A black hole is created when a huge star runs out of fuel for nuclear fusion and collapses under its own gravity. "This model we've done is extremely simple," Pullin said.

Late nights 'sap children's brain power' 8 July 2013Last updated at 19:45 ET By Michelle Roberts Health editor, BBC News online Late nights may have knock-on effects Late nights and lax bedtime routines can blunt young children's minds, research suggests. The findings on sleep patterns and brain power come from a UK study of more than 11,000 seven-year-olds. Youngsters who had no regular bedtime or who went to bed later than 21:00 had lower scores for reading and maths. Lack of sleep may disrupt natural body rhythms and impair how well the brain learns new information say the study authors. They gathered data on the children at the ages of three, five and then seven to find out how well they were doing with their learning and whether this might be related to their sleeping habits.

In Life, Man Immune To HIV Helped Scientists Fight Virus : Shots - Health News hide captionStephen Crohn, a New York artist and editor, carried a genetic mutation that protected him against HIV. He died last month at age 66. The cause was suicide. Stephen Crohn, a New York artist and editor, carried a genetic mutation that protected him against HIV. Stephen Crohn, a man best known for staying alive during the early days of the AIDS epidemic, died Aug. 23 at age 66. Crohn's partner was one of the first people to die from AIDS in 1978. Knowing that there was something unique about himself, Crohn volunteered to be studied. Eventually, scientists realized that Crohn had a genetic anomaly that made him resistant to HIV infection. Immunologist Bill Paxton was one of the first scientists to work with Crohn at the Aaron Diamond AIDS Research Center in New York. HIV normally enters an immune cell by tugging on two receptors on the cell's surface. This genetic change is called the delta 32 mutation. Crohn was an artist and freelance editor. Yes.

Better Humans? Understanding the Enhancement Project, by Michael Hauskeller | Books Andy Miah on the pros and cons of humanity 2.0 If you could enhance one aspect of your biology, what would it be? Would you use cosmetic surgery to make yourself more beautiful? How about cognitive enhancers to improve your memory or wit? These questions are discussed in Michael Hauskeller’s new book, a philosophical exploration of the arguments surrounding human enhancement. He goes on to build up each example of enhancement only to knock it down, broadly rejecting the claim that there is any uncontested value to human enhancement. In short, Hauskeller does not recognise that the journey towards human enhancement has already begun Hauskeller’s analysis often stops short of absolute rejection, more frequently calling into question the legitimacy of arguments favouring enhancement. Many key names associated with this field of study are cited, including John Harris, Nick Bostrom, Julian Savulescu and Michael Sandel. Readers of Better Humans? Nevertheless, Better Humans?

baktun cycle The Psychology of Colors in Logo Design Color psychology has been analyzed by psychiatrists for quite some time. One of the first to analyze colors and how they emotionally affect us was Swiss psychiatrist Carl Jung, who studied them in the early 20th century. Jung thought people could express their emotional feelings through color and used patient therapy painting to determine unconscious color values. Today’s marketers should put a great deal of effort in considering colors for logo designs. To help them in this task, here’s a quick guide. Green Logo Design Image via Flickr by Beyond Jung’s research, one organization often referred to as the “Institute of Colors” is PANTONE®. Green is easily recognized in environmental and recycling logos so it’s an “earth/plant” color that also conveys tranquility and peace. The Hues of Blue Logos Air fresheners and cotton sheet manufacturers use light blues in their logos to promote freshness. Darker blues offer a bolder, regal feel. Trusted and Bold Red Logos

Changing brains: why neuroscience is ending the Prozac era | Science | The Observer Mice are used in research into optogenetics, which suggests that even finer control of the brain may be possible. Photograph: John B Carnett/Popular Science via Getty Images The psychiatric drug age may have reached its peak. The starkest indication that drugs are increasingly being thought of as yesterday's cutting-edge comes from the little mentioned fact that almost all the major drug companies have closed or curtailed their drug discovery programmes for mental and neurological disorders. This is largely because these drugs tend not to be very specific in their effects on the brain. In its place is a science focused on understanding the brain as a series of networks, each of which supports a different aspect of our experience and behaviour. The idea is that we can better understand complex human emotion and behaviour by understanding neural networks. Big money has already been committed. Let's make this clear.

Poverty strains cognitive abilities, opening door for bad decision-making, new study finds As part of the study, researchers conducted experiments on two groups of subjects: low- and middle-income shoppers in a mall in New Jersey, and sugar cane farmers in rural India. In the mall experiment, shoppers underwent a battery of tests to measure IQ and impulse control. However, half the participants were first given a “teaser” question — what they would do if their car had broken down and needed $1,500 worth of repairs — designed to put a pressing financial concerns at the forefront of their thoughts. In India, researchers tested the cognitive capacity and decision-making of farmers before the sugar cane harvest, when they were most strapped for money, and afterwards, when they had fewer financial woes. The results showed that people wrestling with the mental strain of poverty suffered a drop of as much as 13 points in their IQ — roughly the same found in people subjected to a night with no sleep.

TOP 10 IMPOSSIBLE INVENTIONS THAT WORK « Revolutionizing Awareness Searl Effects Generator by Jeane Manning When Leonardo da Vinci sketched out an impossible invention, fifteenth-century scholars probably put him down. Throughout history, experts tell innovators that their inventions are impossible. Perhaps in the 21st century the following inventions will be standard science, and a history student may wonder why 20th-century pundits disregarded them. This class of inventions could wipe out oil crises and help solve environmental problems. Forget the Rube Goldberg mechanical perpetual motion contraptions; they had to stop eventually. Inventors give various names to their space-energy converters. A spiritual commune in Switzerland had a tabletop free energy device running in greenhouses for years, but members feared that outsiders would turn the technology into weaponry. It may have been done before Tesla’s time. The garage inventors come from many backgrounds. One example is U.S. Look, Mom Earth, no power lines! 8. Like this:
