Bubble-powered microrockets zoom have potential to zoom through the human stomach, other acidic environments

  • PDF
TechAndComputer (Feb. 8, 2012) — Scientists have developed a new kind of tiny motor -- which they term a "microrocket" -- that can propel itself through acidic environments, such as the human stomach, without any external energy source, opening the way to a variety of medical and industrial applications. Their report in the Journal of the American Chemical Society describes the microrockets traveling at virtual warp speed for such devices. A human moving at the same speed would have to run at a clip of 400 miles per hour.

Joseph Wang and colleagues explain that self-propelled nano- or microscale motors could have applications in targeted drug delivery or imaging in humans or as a way to monitor industrial applications, such...

Digital worlds can help autistic children to develop social skills

  • PDF
TechAndComputer (Oct. 21, 2011) — The benefits of virtual worlds can be used to help autistic children develop social skills beyond their anticipated levels, suggest early findings from new research funded by the Economic and Social Research Council (ESRC). Researchers on the Echoes Project have developed an interactive environment which uses multi-touch screen technology where virtual characters on the screen demonstrate gestures and  show c...

Virtual reality worm-tracking challenge leads to new tool for brain research

  • PDF
TechAndComputer (Oct. 3, 2011) — Using new optical equipment, a team of 11 researchers put roundworms into a world of virtual reality, monitored both their behavior and brain activity and gained unexpected information on how the organism's brain operates as it moves.

The new research tracking system -- created in collaboration with Eugene-based Applied Scientific Instrumentation Inc. (ASI) -- should help neuroscientists around the world who use...

Virtual water cannot remedy freshwater shortage

  • PDF
TechAndComputer (June 7, 2011) — The implementation of virtual water into trading deals has been suggested as a realistic solution to solving the global inequality of renewable freshwater, but new research suggests that it may not be as revolutionary as first thought.

In a study published June 7, in IOP Publishing's journal Environmental Research Letters, researchers have claimed that virtual water is unlikely to increase water use equality,...

Weight loss success in a 3-D virtual world

  • PDF
TechAndComputer (June 3, 2011) — Participants in two weight-loss programs -- one involving traditional health club sessions and the other delivered online in a 3D virtual world -- lost similar amounts of weight and body fat, but the online contingent reported significantly greater gains in behaviors that could help them live healthier and leaner lives.

"It's counter-intuitive, the idea of being more active in a virtual world, but the activities...
