Tech universe: Thursday, 15 July

By Miraz Jordan

A round-up of the latest technology news from around the globe.

RUNNING BIKE: Can't decide whether to go for a run or a bike ride? You don't need to choose. The ElliptiGO has 2 wheels, handlebars and huge pedals, but no seat. Ride it by 'running' on the pedals, to reach up to 40Kph. Weird, but in a cool and very clever way. See more here and a video on YouTube.

SEE ME, HEAR ME: Or at least, my clothes. Massachusetts Institute of Technology add graphite electrodes to synthetic fabrics so they can detect light and sound, and can even talk. Your whole shirt could be a microphone or a speaker. "Is that your shirt talking?"

SEE MY SKY: See Mars in 3D or the whole night sky in 2D. The Virtual WorldWide Telescope uses terabytes of real images from ground and space-based telescopes all over the world. Space is big: vastly,
hugely, mind-bogglingly big.

3D HEADACHE: About 1 in 10 of us can't see straight: we can't correctly process separate images that come from our right and left eyes. This causes problems if we try to watch 3D movies.

So if Avatar gave you a headache, it may have been your eyes, not the plot that was the problem. The British Eyecare Trust has the details.

SQUEEZE BATTERY: A small box with Xenon difluoride under a million atmospheres of pressure stores more condensed energy than any other battery ever built. Wonder how it would go in my iPod? Read more at iO9.
