+ - Physicists show self-correcting quantum computers are theoretically possible->

Submitted by InfiniteZero
InfiniteZero (587028) writes "From the article at phys.org:

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.""

+ - An Asian Origin for Human Ancestors?-> 2

Submitted by InfiniteZero
InfiniteZero (587028) writes "Researchers agree that our immediate ancestors, the upright walking apes, arose in Africa. 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."

Science

+ - Exercise Makes You Smarter 1

Submitted by InfiniteZero
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."

+ - Research Reveals 4.74 Degrees of Kevin Bacon->

Submitted by InfiniteZero
InfiniteZero (587028) writes "NPR reports that according to Facebook and researchers from the University of Millan, the average separation — or "number of hops" — between Facebook users is now 4.74. In other words, that's the average number of steps it would take to connect one Facebook user with another who uses that social media site."

Space

+ - Russians set for Mars adventure->

Submitted by InfiniteZero
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."

The Military

+ - Cyber weaknesses should deter US from waging war-> 1

Submitted by InfiniteZero
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.'"

+ - Stars Found to Produce Complex Organic Compounds->

Submitted by InfiniteZero
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."

+ - Cleaning Up Japan's Radioactive Mess with Blue Goo->

Submitted by InfiniteZero
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."

+ - iRobot + Kinect = Robotic Overlord->

Submitted by InfiniteZero
InfiniteZero (587028) writes "Philipp Robbel, a student at MIT’s Personal Robotics Group, has hacked together the Kinect 3D sensor with an iRobot Create platform and assembled a battery powered bot that can see its environment and obey (sure) your gestured commands. Will they include the three laws of robotics in the next firmware update?"

Biotech

+ - Reprogrammed Skin Cells Turned into Baby Mice->

Submitted by InfiniteZero
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.'"
