Biofeedback video game helps kids control anger

Researchers at Boston Children's Hospital had the bright idea that, since kids with anger-control problems tend to resist psychotherapy but enjoy video games, the researchers should develop a game that sneakily helps kids practice emotion-control skills -- and in the process perhaps reduces the need for medication.

The game, called RAGE Control (short for Regulate and Gain Emotional Control), employs a finger heart rate monitor; users with elevated heart rates actually lose the ability to shoot enemy spaceships. Researchers say the idea is to teach kids to better control their emotional responses -- and specifically to reduce outbursts of … Read more

Nokia sinks deeper into junk status with new S&P downgrade

The bad news just keeps coming for Nokia.

Standard & Poor's Ratings Services today announced that it has downgraded Nokia's long-term corporate credit rating from BB+ to BB-.

S&P has affirmed an even worse B rating on Nokia's short-term credit.

"The rating actions reflect a downward revision of our estimates of revenues and profitability for Nokia's smartphone operations in 2012 and 2013,&… Read more

Digital 'pill' tells doctors when you've swallowed it

If you're not afraid to swallow your technology, you may want to check out new tech cleared by the Food and Drug Administration this week that lets you ingest a digital sensor powered by stomach acid that alerts your doctors about your health and your treatment habits.

The technology consists of a tiny, silicon-based sensor that, at 1mm wide (roughly the size of a grain of sand), can be consumed via pills and pharmaceuticals and pass through the body much like high-fiber food.

According to the developer, Proteus Digital Health, once the sensor is swallowed, stomach fluids that come into contact with it provide enough power to relay a signal that documents exactly when it was taken. This data is transmitted to a battery-powered patch worn on the skin that detects the signal and records the exact time the sensor was swallowed.… Read more

Microsoft explains how Windows 8 smokes Windows 7

Microsoft spelled out acceleration improvements in Windows 8, in a blog post Monday. Needless to say, Microsoft says the overall experience is a lot snappier.

Imperfect 10s: Best TVs for design, features, picture quality, and value

Maybe you don't care how many features a TV has. Maybe you just want to see the coolest design going. Maybe all you want is the best bang for your buck, or the best picture regardless of cost.

Lucky for you, CNET's reviews have subratings. All of our TV reviews are rated according to four criteria -- Design, Features, Picture quality, and Value -- that are weighted, sifted, and centrifuged into the overall star rating.

Unfortunately you can't sort CNET's TV reviews by subrating on the Web site yet, so in the meantime I present the four TVs that would be perched at the top of those sorted lists. Each scored the only "10" we've awarded so far this year in the subratings mentioned above; they're not perfect, but a "10" is as good as it gets. I also list runners-up and potential challengers in each subcategory.
