| Dip chip technology tests toxicity on the go Posted: 14 May 2012 10:42 AM PDT Researchers have developed a portable "dip chip" that detects water toxicity quickly and accurately. Once perfected, the chip might be plugged into ordinary smartphones or PDA devices to provide a toxicity alert.  |
| Amateur astronomers boost ESA’s asteroid hunt Posted: 14 May 2012 09:26 AM PDT ESA's Space Situational Awareness (SSA) programme is keeping watch over space hazards, including disruptive space weather, debris objects in Earth orbit and asteroids that pass close enough to cause concern.  |
| Floating robots use GPS-enabled smartphones to track water flow Posted: 14 May 2012 07:50 AM PDT A fleet of 100 floating robots took a trip down the Sacramento River on May 9, in a field test. The devices, equipped with GPS-enabled smartphones, demonstrated the next generation of water-monitoring technology, promising to transform the way government agencies track one of the state's most precious resources.  |
| You can't play nano-billiards on a bumpy table Posted: 14 May 2012 07:49 AM PDT There's nothing worse than a shonky pool table with an unseen groove or bump that sends your shot off course: a new study has found that the same goes at the nano-scale, where the "billiard balls" are tiny electrons moving across a "table" made of the semiconductor gallium arsenide. Physicists have shown that in this game of "semiconductor billiards," small bumps have an unexpectedly large effect on the paths that electrons follow.  |
| Real smart: Protective clothing with built-in A/C Posted: 14 May 2012 07:44 AM PDT In order to test a new 'smart' protective vest, an experimenter wearing one jogged several kilometers on a treadmill in a climate-controlled chamber. During the jog he lost 544 grams in weight through sweating – but thanks to the vest's integrated cooling system this was still 191 grams less than if he had been wearing a conventional garment.  |
| Scientists generate electricity from viruses Posted: 13 May 2012 11:46 AM PDT Scientists have developed a way to generate power using harmless viruses that convert mechanical energy into electricity. The scientists tested their approach by creating a generator that produces enough current to operate a small liquid-crystal display. Their generator is the first to produce electricity by harnessing the piezoelectric properties of a biological material.  |
