Leap Motion giving 10,000 developers free Leaps

Leap Motion, which created an innovative gesture control technology that measures users' movements to an accuracy of a hundredth of a millimeter, is expanding its developer program and releasing a new software development kit.

According to Michael Buckwald, CEO of the San Francisco startup, Leap Motion is giving 10,000 developers free Leap units over the next two weeks in a bid to dramatically increase the number of potential applications being designed to work with the new technology.

All told, 40,000 people have applied to be part of Leap Motion's developer program, in part because the number of … Read more

Violent video games and aggression: A cumulative effect?

Video games are the subject of so many studies, not to mention findings. Some suggest cognitive benefits, others behavioral issues that may or may not persist over time.

Many of these studies are small enough to require further investigation, and the journalists reporting on them often confuse correlation (when results happen in tandem) with causation (when one action is shown to result from another).

A new study out of Ohio State University suffers from a small sample size (70 participants), but its findings -- that people who play violent video games for three consecutive days show increases in aggression and hostility … Read more

Quantum computing goes mainstream? New VC fund debuts

Quantum computing tends to sounds like something out of a science fiction novel or at least The Big Bang Theory. But a new venture capital fund, launching today, is trying to take it mainstream.

The Quantum Wave Fund, which will set up shop in Boston, plans to invest solely in early stage, private companies working on breakthroughs in quantum technology. It won't be providing funding for early research but instead will seek out companies who already have viable and promising products related to quantum computing.

"Too many people take quantum computing as hypothetical," Serguei Kouzmine, managing partner … Read more

Microsoft gives $75,000 to team building cloud-based stethoscope

Pneumonia, which claims the lives of more than 1.2 million children under the age of 5 every year, is the leading cause of death in children worldwide, according to the World Health Organization. And in certain regions, such as South Asia and sub-Saharan Africa, pneumonia alone accounts for 85 percent of pediatric deaths.

So it comes as little surprise that Microsoft, through its Imagine Cup Grants program, has awarded its second-place prize of $75,000 to a team out of Australia that is developing a tool to diagnose the infection quickly and affordably. (The first-place prize went to a … Read more

Giant CO2 spheres invade NYC

With its many pedestrians and subway users, New York seems like one of the greener cities in the U.S. But it still produced a gob-smacking mountain of carbon emissions in 2010.

In the vid below from graphics firm Carbon Visuals, the 54 million tons of CO2 is illustrated as a mass of spheres that tower over the city, engulfing its buildings.

Some 75 percent of the pollution came from buildings, with the bulk of the rest from transport, according to the firm, which used city data. … Read more

This smiley face tattoo is monitoring you

A Ph.D. student at the University of Toronto is using the same transfer paper currently affixing temporary tattoos to kids -- in conjunction with a common screen-printing technique -- to develop a medical sensor that keeps tabs on a person's exertion by monitoring the skin's pH levels.

Similar devices, which are called ion-selective electrodes (ISEs), are already common among athletic trainers and medical researchers to help spot fatigue, dehydration, or even metabolic diseases. But they tend to be bulky and don't stick well to sweaty skin.

The new sensor stays put and doesn't look so, … Read more

Polymer dollars: Fingering Canada's plastic bills

Her majesty looks fantastic in plastic.

A polymer portrait of Queen Elizabeth II is in many Canadian wallets now that a new $20 bill packed with anti-forgery tech is in circulation.

The plastic note follows the circulation of new plastic $100 and $50 bills, but since it changes hands with greater frequently, more Canadians are taking notice.

Reactions to have been mixed. Some say the bills tend to stick together in stacks and ATMs, others have praised their security features, and some say they look like play money.

Apart from Braille-like raised dots for visually impaired users, the twenty's … Read more

New calculator predicts newborn's obesity risk

Next time you see an obese adolescent, blame the parents. At least that's what researchers at the Imperial College London are suggesting. They have developed a calculator to predict a newborn's chances of developing childhood or adolescent obesity

With only one in 10 cases of obesity being the result of a rare genetic mutation, researchers set out to determine which environmental factors played the largest roles in the development of childhood obesity.

"Once we compare different statistical models, and we added the genetic variants [associated with causing obesity], their ability to explain childhood obesity didn't improve … Read more

3D printer on moon or Mars could make tools from local rocks

NASA is already experimenting with 3D-printing components for rockets to Mars, but the fun doesn't have to stop at liftoff.

Researchers at Washington State University and NASA are suggesting that rocks on the moon or Mars could be used to print useful objects like tools or replacement parts.… Read more
