Technically, any sound moves electrons, since electrons are part of the atoms that move in pressure waves. But now scientists are using sonic waves to move an electron down a wire perfectly - with no loss of information. Then they played ping-pong with it. Typical. More »

A team of engineers today announced a discovery that could change the world of electronics forever. Called an "epidermal electronic system" (EES), it's basically an electronic circuit mounted on your skin, designed to stretch, flex, and twist — and to take input from the movements of your body.

As most people know, a few hours of having an ear bud in their ear leaves them sore and unable to listen any longer. Scientists have figured out what happens during 'listener fatique,' and designed pump-action ear buds that can solve the problem. Find out how you can rock and roll all night, and party every day.

Engineers have used human blood to make a 'memristor,' a component that remembers its last use and adapts to it. More »

Wine makes superconductors better at their jobs. And apparently, it makes some scientists better at their jobs too. More »

The first electronic instrument, the theremin, was popularized by 1950s scifi films and the original Star Trek theme song. It has no strings and no keyboard, and was invented in the 1920s. Find out how it works. More »

Mirrors are usually surfaces that reflect light, which means photons bounce off of them. But a new kind of magnetic mirror can reflect magnetized atoms - one at a time. More »

Modern computers rely on electrons moving through wires to transmit information, which is far, far slower than the fast-as-light optics we theoretically could be using. And now we've found the exotic material that might allow us to leave electrons behind. More »

When I see scifi flicks from the 1960s and 70s, I always love the blocky, blinky lights on all the computers. Though they were obviously considered "futuristic" at some point before we all started fetishizing miniaturization and gesture-based computers. But now the DiY geeks over at Hackaday have found a way to make those blinky blocks into something useful: a keypad combination lock. Instead of keying a number sequence into it, you can key a color sequence. It's a great home electronics project, and it makes your front door look like it should open with that Star Trek "fffwwp!" noise. More »

Now you can power your cell phone just by wearing a special shirt made of two tiny layers of nanowires that rub against each other as you move. These super-conductive wires are "piezoelectric," generating energy through pressure and movement. The result is a shirt that generates more electricity the more you move around. A few weeks ago, a research team at Georgia Tech announced the first generation power shirt (you can see the two layers of nano wires above), speculating that it could someday power small electronic devices like iPods or mobiles.
