It seemed like the perfect setup--give kids video games that would motivate them to get off the couch and start moving. Not only would they have fun, they would also get healthier.

However, these high hopes may have been wishful thinking. According to a new study by Baylor College of Medicine in Houston, Texas, kids given "active" video games showed no more overall physical exertion than kids who used only their thumbs to play.

"There was no evidence that children receiving the active video games were more active in general, or at anytime, than children receiving the … Read more

The online video game World of Warcraft is in the news again, this time for its potential to help boost certain cognitive skills--specifically spatial ability and focused attention--in older adults.

Researchers at North Carolina State University's Gains Through Gaming Lab tested the cognitive functions of 39 60- to 77-year-olds and then broke the study's participants into an experimental group, which played the MMORPG for 14 hours over a two-week period, and a control group, which did not play WoW at all.

It turns out that the adults who played WoW for two weeks improved their baseline scores, with … Read more

A relatively mundane data-link problem could explain last year's surprising finding that subatomic particles called neutrinos appeared to violate physics laws by traveling faster than the speed of light.

Problems with a fiber-optic link in the Opera experiment "could have led to an underestimate of the time of flight of the neutrinos," CERN, the European nuclear physics center that generated the neutrinos for the experiment, said in a statement today. The fiber fed GPS location data into the experiment's master clock.

Too short a travel time to the destination--Italy's National Institute of Nuclear Physics lab … Read more

As implantable medical devices become smaller and less power hungry, they are taking on a variety of new roles. What began as largely stationary objects, such as pacemakers and cochlear implants, are becoming small enough to actually pass through our bodies (i.e. in the form of pills) to deliver drugs and perform diagnostics.

Now, a new class of medical devices is emerging that adds a twist to the traditional implant: the devices are so small that they can travel through our bloodstream, not to mention are powered wirelessly via electromagnetic radio waves, according to Stanford electrical engineer Ada Poon.

By moving through the bloodstream, these tiny implants will be able to perform minor surgeries such as removing blood clots, Poon told an audience at the International Solid-State Circuits Conference in San Francisco this week.… Read more

Many with ALS or high-level spinal-cord injuries have been relying for years on the old sip-and-puff technology to operate wheelchairs and computers. This tech requires the user to sip or puff precise amounts of air pressure into a straw, and it is anything but subtle.

The operation of wheelchairs and other devices could soon be far less conspicuous, thanks to a prototype dental retainer developed at the Georgia Institute of Technology--for those who don't mind getting their tongues pierced, that is.

Featuring a small retainer that fits along the roof of the mouth, the Tongue Drive System uses … Read more

Most of us have at least tried to text without looking at our phones before. I confess to having shot off a quick message while stopped at a red light, or immediately following crazy goals and tackles at soccer matches, or even from the confines of my pocket at parties.

Now a free, open-source app called BrailleTouch is about to make this form of multitasking that much easier--for the visually impaired and sighted alike.

Designed at Georgia Tech, the app incorporates the Braille writing system into a touch-screen device. It essentially turns an iPhone's touch screen into a soft-touch … Read more

We humans seem to have the capacity to fear just about anything these days. From chromophobia (fear of colors) to genuphobia (fear of knees or kneeling), optophobia (fear of opening one's eyes) to selenophobia (fear of the moon), we've been able to identify just about any phobia imaginable.

So it should come as no surprise that nomophobia, the fear of being out of mobile phone contact, exists at all, let alone may afflict as many as two in three adults, according to a new survey out of the U.K.

When it comes to cancer cells, a particularly confounding breed called cancer stem cells have proven difficult to kill. Because they divide so slowly, chemo drugs do them little harm, and they appear resistant to heat therapies that are generally good at killing most cells. Some cancer drugs even appear to promote the growth of cancer stem cells.

Now, three years after they found that the heat from 30-second laser blasts can kill kidney cancer stem cells, researchers at Wake Forest Baptist Medical Center say the same treatment works to kill breast cancer stem cells as well.

If you're wondering whether you're too many cups or too many hours into the day for yet another jolt of caffeine, a free app developed by researchers at Pennsylvania State University aims to help.

In building the Caffeine Zone app, professors representing several disciplines relied on peer-reviewed studies to devise a simple formula: those with between 200 and 400 milligrams of caffeine in their bloodstream are in the optimal mental alertness zone, while anyone above 100 milligrams has entered the good-luck-sleeping-anytime-soon zone.

"Many people don't understand how caffeine levels in their bloodstream go up and how … Read more
