For the first time, physicists have demonstrated that information can flow through a diamond wire.
In the experiment, electrons did not flow through diamond as they do in traditional electronics; rather, they stayed in place and passed along a magnetic effect called “spin” to each other down the wire — like a row of sports spectators doing the wave.
Spin could one day be used to transmit data in computer circuits — and this new experiment, done at The Ohio State Univ., revealed that diamond transmits spin better than most metals in which researchers have previously observed the effect.
Researchers worldwide are working to develop so-called “spintronics,” which could make computers simultaneously faster and more powerful.

When kids are involved in contact sports like soccer and football, there’s a common parental fear of injury, and even when youngsters are at home just playing — chasing, roughhousing, jumping on trampolines and the like — worries are constant because, let’s face it, it’s easy to get hurt. And while most injuries are readily apparent, concussions are particularly scary, because it’s often very hard to discern when one has occurred.According to the American Medical Society for Sports Medicine, up to half of all concussions are not reported —which isn’t surprising given this related statistic: 47 percent of athletes feel no symptoms directly after receiving a concussive blow.

People began dreaming of intelligent computers from the moment the computer was invented, but few people had any idea of how to bring it about. Part of the problem was the fact that few knew how the human brain worked, and so any attempt to make machines intelligent would be like recreating a statue that one was not permitted to look at. In 1958, a particular theory gained favor with computer scientists. It has also gained favor with neuroscientists - but with a twist that might make computers as filled with biases and blindspots as humans.

Classical computers are only as good as the number of transistors they have. According to Moore’s Law, that number doubles every two years.
That pace may soon slow, but there’s an alternative: quantum computing, which relies not on transistors but on particles to perform calculations much more quickly. Speaking at the Gigaom Structure Data conference Wednesday, D-Wave Systems president and CEO Vern Brownell said that many of the major computing breakthroughs over the next decade will be dedicated to quantum computing, and computers will improve much more rapidly than the world is used to seeing.
“You will see many orders of magnitude improvement on each generation, rather than the 2X or 5X that we typically see in classical computing,” Brownell said.

New York --
IBM is teaming up with the New York Genome Center to help fight brain cancer.
The company said Wednesday that its Watson cloud computing system will be used in partnership with a genetic research center based in New York mainly to help sequence DNA for the treatment of glioblastoma, the most common type of brain cancer in U.S. adults.
New York Genome Center, a consortium of academic, medical and industry officials, will use Watson to sequence the DNA of cancer tumors at a much faster rate than would be possible if done by a human being. The DNA information would then be combined with clinical information and fed to Watson to help determine the best way to treat a particular patient.

Researchers at University of California San Diego and the University of Toronto have found that computers are far better than humans at recognizing the difference between real and fake pain in the faces of test subjects. In fact, while humans could tell the difference 55 percent of the time, robots could tell it 85 percent of the time.
“In highly social species such as humans, faces have evolved to convey rich information, including expressions of emotion and pain,” said Kang Lee, a senior author. “And, because of the way our brains are built, people can simulate emotions they’re not actually experiencing – so successfully that they fool other people. The computer is much better at spotting the subtle differences between involuntary and voluntary facial movements.”

One baby born with a defective windpipe now has hope of breathing normally thanks to 3-D printing technology, NPR reported.
Garrett Peterson, now 18 months old, was born with tracheomalacia – a condition that caused his trachea to be so weak that it collapsed easily, leaving him unable to breathe. The condition terrified his parents, who turned to specialist Dr. Glenn Green at the University of Michigan for a possible treatment.
Along with Scott Hollister, a biomedical engineer who runs the university’s 3-D printing lab, Green designed a device that can hold open Garrett’s windpipe until it’s strong enough to function independently. After taking a CT scan of Garrett’s windpipe to make a replica of it, they made the “splint” with a 3-D printer.

The stubbornly low number of female computer science students in the United States has generated a pile of academic studies, ample hand-wringing and a wide-ranging discussion in tech and education circles about what can be done to boost the number of women choosing computing careers.
All of which raises a fair question: What difference does it make if women don’t join the tech workforce in the same numbers that men do?
It turns out it makes a huge difference. The dearth of women in computing has the potential to slow the U.S. economy, which needs more students in the pipeline to feed its need for more programmers. It harms women by excluding them from some of the best jobs in the country. And it damages U.S. companies, which studies show would benefit from more diverse teams.

Computer science education is getting something of a fresh look from state and local policymakers, with many starting to push new measures to broaden K-12 students' access to the subject.
Seventeen states and the District of Columbia now have policies in place that allow computer science to count as a mathematics or science credit, rather than as an elective, in high schools—and that number is on the rise. Wisconsin, Alabama, and Maryland have adopted such policies since December, and Idaho has a legislative measure awaiting final action.

The deadline for installing secure operating systems on federal government computers will pass next month with the job incomplete, leaving hundreds of thousands of machines running outdated software and unusually vulnerable to hackers.
Federal officials have known for more than six years that Microsoft will withdraw its free support for Windows XP on April 8, 2014. Despite a recent rush to complete upgrades, an estimated 10 percent of government computers — out of several million — will still be running the operating system on that date, company officials said.
