  • Computing: Swapping a glove for the keyboard

    PITTSBURGH, Pa. — Today people use keyboards and mice to enter data into computers. They play harps and guitars by strumming strings. They play violins and cellos with a bow. But one day soon, a high-tech glove might be able to stand in for any or all of these devices and instruments, says Malav Shah.

    The 15-year old at R.C. Clark High School in Plano, Texas, developed such a glove. He...

  • What’s the buzz? A new mosquito lure

    PITTSBURGH, Pa. — Male mosquitoes track down potential mates by homing in on the sound emitted by the wings of flying females. But stereo speakers that broadcast the female’s buzz can easily fool the males, a teen researcher finds. If those guys become so attracted to the fake buzzing, they might just ignore the real gals. And that could trim populations of these disease-carrying bugs by...

  • 3-D Recycling: Grind, melt, print!

    Three-dimensional, or 3-D, printers make it possible to “print” almost any object with a computer. The machines produce items by laying down tiny drops, or pixels, of material one layer at a time. That material can be made from plastic, metal or even human cells. But just as the ink for standard computer printers can be expensive, 3-D printer “ink” can be quite pricey too. Meanwhile, society...

  • Science in Hollywood

    There’s so much snow in the movie Frozen that the cold white stuff might as well be the star of the animated film. It falls, flies, piles and melts. Snow sprays through the air as Anna and Kristoff cling to a reindeer-pulled sleigh, barely escaping a pack of snarling wolves. Snow dances in the air as Elsa uses her special powers to build an icy fortress on a lonely mountain. The movie even...

  • This ‘smart’ self-cleaning keyboard is powered by you

    A new keyboard can tell if you’re its owner. It locks out anyone else, even if that person knows your password. What’s more, this device needs no batteries. It harvests all the energy it needs from the action of your typing.

    All in all, “This will hugely improve the security of a computer,” predicts Zhong Lin Wang. He’s a materials scientist at the Georgia Institute of Technology in...

  • Don’t hold ’em – just fold ’em

    The best poker player in the world doesn't have a poker face. In fact — it has no face at all.

    The new poker expert is an algorithm (AL-go-RITH-em), or problem-solving program. Called Cepheus, it has solved one form of this card game. “Solved,” in this case, means the program knows the game well enough to win against any human.

    And this new algorithm may be useful beyond the card...

  • Virtual wounds: Computers probe healing

    When you fall off your bicycle, slamming your knee into the pavement, your attention focuses on the pain. But the rest of your body is focusing on something else. Your injury has just begun rallying a large number of your cells to do serious battle.

    Under your bruises and scratches, an army of fighter cells begins mobilizing. In the next few minutes to days, these troops will blast apart...

  • Explainer: What is a computer model?

    Computers use math, data and computer instructions to create representations of real-world events. They also can predict what’s happening — or what could happen — in complex situations, from climate systems to the spread of rumors throughout a town. And computers can spit out their results without people having to wait years or to take big risks.

    The scientists who build computer models...

  • Models: How computers make predictions

    You line up a football to kick a field goal. Will you make it?

    Success will depend on lots of things. Your distance from the goal post, the strength of your kick, your focus, and even the angle of your foot — all will affect the outcome. Even the wind will make a difference.

    Each of these factors is known as a variable. That means each can vary, or change. Some variables also can...

  • 3-D printers are making cars!

    On a Saturday morning earlier this September, the world got its first look at the Strati. This electric vehicle is unlike any other currently on the road. It rolls on four wheels, but its body and chassis weren't built in a factory. Instead, Strati's designers used a technology called 3-D printing. It created those parts of the car in one piece, from the ground up.

    “Compared to a typical...
