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.

A chimp-pig hybrid origin for humans? (Phys.org) —These days, getting a Ph.D. is probably the last thing you want to do if you are out to revolutionize the world. If, however, what you propose is an idea, rather than a technology, it can still be a valuable asset to have. Dr. Eugene McCarthy is a Ph.D. geneticist who has made a career out of studying hybridization in animals. He now curates a biological information website called Macroevolution.net where he has amassed an impressive body of evidence suggesting that human origins can be best explained by hybridization between pigs and chimpanzees. Extraordinary theories require extraordinary evidence and McCarthy does not disappoint. Generally speaking, interspecies hybrids—like mules, ligers (lion-tiger hybrids), or zedonks (zebra-donkey hybrids)—are less fertile than the parents that produced them. It is not yet clear if or when genetic data might support, or refute, our hybrid origins. Follow-up story: Human hybrids: a closer look at the theory and evidence Share Video

60 billion potential alien planets in our own galaxy, study finds - Columbia Events Just how many exoplanets, or planets outside our own Solar System, might harbor life? According to a new study, 60 billion or so, reported Space.com (via Yahoo News) on July 2. And that is just inside the Milky Way, our home galaxy. And that's just around one type of star -- a Red Dwarf. Scientists from Northwestern University and the University of Chicago have doubled the number of Earth-sized planets that could potentially be found within the habitable zone (also known as the "Goldilocks Zone" for being "just right" in astronomical distance to support life) of Red Dwarf stars. In short: Cloud cover on alien planets added up to 60 billion planets potentially capable of harboring alien life -- or at least liquid water. The research was published in the journal Astrophysical Journal Letters in late June. In a statement, study researcher and assistant professor in geophysical sciences at the University of Chicago Dorian Abbot, said: "Clouds cause warming, and they cause cooling on Earth.

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 Light stopped completely for a minute inside a crystal: The basis of quantum memory Scientists at the University of Darmstadt in Germany have stopped light for one minute. For one whole minute, light, which is usually the fastest thing in the known universe and travels at 300 million meters per second, was stopped dead still inside a crystal. This effectively creates light memory, where the image being carried by the light is stored in crystals. Beyond being utterly cool, this breakthrough could lead to the creation of long-range quantum networks — and perhaps, tantalizingly, this research might also give us some clues on accelerating light beyond the universal speed limit. Back in 1999, scientists slowed light down to just 17 meters per second, and then two years later the same research group stopped light entirely — but only for a few fractions of a second. To stop light, the German researchers use a technique called electromagnetically induced transparency (EIT).

Netherlands UFO Photos: Experts Say Pictures Not Faked UFO photographed in Netherlands Image Credit: YouTube/UFOvni2012 An Unidentified Flying Object accidently photographed last month above the skies of Muiderslot Castle, a medieval monument built in 1285 near Amsterdam in the Netherlands, set the internet abuzz this week. After much speculation on the authenticity of the pictures, experts now suggest that though the video is "not fake" or doctored, there is perhaps an explanation to what can be seen in the picture. The picture in question was clicked on 25 May by Corinne Federer who was visiting the historic building with her mother. "I was shooting with a very wide angle lens Nikon 14-24 which can capture quite a large scene. Speaking further about what she saw, Federer told Huffington Post: "It was a tubular-shaped object that had an S-shaped fin on it. "I looked at the image information -- at the shutter speed -- and (the object) was blurred at 1/250th of a second, so it had to be going superfast," she added. "I found another object.

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:
