Using exotic components such as color codes, new phases of quantum matter, and extra dimensions, a team of physicists has shown that it's theoretically possible to construct a quantum computer that has the ability to correct itself whenever an error occurs.
"The greatest significance of our work is showing that self-correcting quantum computing at a finite temperature is not impossible as a matter of principle," physicist Héctor Bombin told Phys.org. Bombin was at MIT in Cambridge, Massachusetts, while performing the study and is currently at the Perimeter Institute in Waterloo, Ontario. "In fact, the original motivation came from claims to the contrary by other authors. We provide explicit constructions that can be checked directly, without numerical simulations.""

But the discovery of a new primate that lived about 37 million years ago in the ancient swamplands of Myanmar bolsters the idea that the deep primate family tree that gave rise to humans is rooted in Asia. If true, the discovery suggests that the ancestors of all monkeys, apes, and humans—known as the anthropoids—arose in Asia and made the arduous journey to the island continent of Africa almost 40 million years ago."

InfiniteZero (587028) writes "Latest studies from the University of Tsukuba in Japan indicates that exercise increases the baseline level of glycogen (stored carbohydrates) in the brain, especially in the frontal cortex and the hippocampus which are critical to thinking and memory. According to professor Hideaki Soya, senior author of the studies, while a brain with more fuel reserves is potentially a brain that can sustain and direct movement longer, it also may be a key mechanism underlying exercise-enhanced cognitive function.
Dr. Soya also suggests that D.I.Y. "glycogen supercompensation" efforts seem like an attractive possibility, and the process may even be easy." top
InfiniteZero (587028) writes "Russia is about to launch an audacious bid to scoop up rock and dust samples from the Martian moon Phobos and bring them back to Earth for study. Detailed mapping of the moon has been conducted by the European Space Agency's Mars Express (MEx) satellite, and this information is being used to identify a suitable location to land in February 2013. The French space agency (Cnes) has provided instrumentation. The European Space Agency, in addition to its survey information from MEx, will be providing ground support. US participation comes in the form of the space advocacy group, The Planetary Society, which is sending its Living Interplanetar Flight Experiment (LIFE). This package of hardy micro-organisms will make the journeys out and back inside a separate compartment in the return capsule. It is a significant venture also because it will be carrying China's first Mars satellite." Link to Original Source top

InfiniteZero (587028) writes "America's critical computer networks are so vulnerable to attack that it should deter U.S. leaders from going to war with other nations — Richard Clarke, a former top U.S. cybersecurity official said Monday. The U.S. military is entirely dependent on computer systems and could end up in a future conflict in which troops trot out onto a battlefield 'and nothing works.'" Link to Original Source top
InfiniteZero (587028) writes "Researchers at the University of Hong Kong observed stars at different evolutionary phases and found that they are able to produce complex organic compounds and eject them into space, filling the regions between stars. The compounds are so complex that their chemical structures resemble the makeup of coal and petroleum, the study's lead author Sun Kwok, of the University of Hong Kong, said."

InfiniteZero (587028) writes "A clever technology is helping hazmat crews in Japan contain and clean up the contamination caused by the ongoing nuclear disaster there: a blue liquid that hardens into a gel that peels off of surfaces, taking microscopic particles like radiation and other contaminants with it. Known as DeconGel, Japanese authorities are using it inside and outside the exclusion zone on everything from pavement to buildings." Link to Original Source top
InfiniteZero (587028) writes "According to this WSJ story, 'Two teams of Chinese researchers working separately have reprogrammed mature skin cells of mice to an embryonic-like state and used the resulting cells to create live mouse offspring. The reprogramming may bring scientists one step closer to creating medically useful stem-cell lines for treating human disease without having to resort to controversial laboratory techniques. However, the advance poses fresh ethical challenges because the results could make it easier to create human clones and babies with specific genetic traits.'" Link to Original Source
