New "4D-printing" material can change shape in hot water

By - April 29, 2015 1 Picture
Researchers at the University of Wollongong, Australia have created a 3D printer-compatible hydrogel that is mechanically tough and able to repeatedly change shape in response to water temperature. The scientists have demonstrated the technology by 3D-printing an autonomous water valve, but the material could also be used to create soft robots, custom designed sensors and self-assembling macrostructures.

The Hunger Pains: Mice genetically engineered to not feel them

By - April 28, 2015 1 Picture
Hunger pains are the bane of any dieter's existence, kicking in even when skipping a single meal and goading the sufferer to indulge their desire for food. Controlling hunger is now better understood as neuroscientists tease apart why we (well, our model mouse cousins) feel hunger. Mind-bendingly, the same researchers have used genetic therapies to create feelings of satiety where none would otherwise exist. Read More

MIT develops technique to see tiny vibrations in large structures using high-speed video

By - April 27, 2015 2 Pictures
While it might appear that large structures, such as bridges and buildings, remain entirely unmoved by everyday forces like rain and wind, the truth is that they do experience very slight vibrations, too small to be seen by the human eye. Those vibrations can be indicative of structural damage or instability, but current methods of detecting them are impractical and costly. A new technique developed by MIT researchers is designed to spot those telltale signs of weakness using high speed video and a computer vision technique. Read More

Disney tech may lead to better dubbing of foreign films

By - April 22, 2015 1 Picture
Here's something you might not know about foreign-language films ... when they're dubbed to English, the editors don't necessarily just go with the most literal translation. Instead, they observe the actors' lip movements, then choose English dialogue that at least somewhat matches up with those. Now, a team from Disney Research Pittsburgh and the University of East Anglia has developed a system that does so automatically, and that offers a wider range of suggested alternate phrases.

Italian company hopes to market synthetic eyeballs

By - April 22, 2015 7 Pictures
Imagine being able to see in black and white or with an Instagram-like filter, or to have what you see through your eyes transmitted wirelessly, simply by swallowing a pill. Or imagine having vision so sharp and accurate that your visual acuity is on par with the most sight-adept people in the world. Italian research studio Mhox hopes to one day make this a reality with its EYE concept, which would offer 3D bioprinted eyes that replace your existing eyeballs. Read More

New device combines the advantages of batteries and supercapacitors

By - April 19, 2015 2 Pictures
Scientists at UCLA's California NanoSystems Institute have developed a new device that combines the high energy densities of batteries and the quick charge and discharge rates of supercapacitors. The hybrid supercapacitor is reportedly six times as energy-dense as a commercially available supercapacitor and packs nearly as much energy per unit volume as a lead-acid battery. Read More
