Research: 'Buckliball' opens new avenue in design of foldable engineering structures

Posted: 26 Mar 2012 01:08 PM PDT

Inspired by a toy, the 'buckliball' -- a collapsible structure fabricated from a single piece of material -- represents a new class of 3-D, origami-like structures.

Butterfly wings' 'art of blackness' could boost production of green fuels

Posted: 26 Mar 2012 01:06 PM PDT

Butterfly wings may rank among the most delicate structures in nature, but they have given researchers powerful inspiration for new technology that doubles production of hydrogen gas — a green fuel of the future — from water and sunlight.

Tiny reader makes fast, cheap DNA sequencing feasible

Posted: 26 Mar 2012 01:06 PM PDT

Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available.

Computer system identifies liars

Posted: 26 Mar 2012 10:35 AM PDT

Computer scientists are exploring whether machines can read the visual cues that give away deceit. Results so far are promising: In a study of 40 videotaped conversations, an automated system that analyzed eye movements correctly identified whether interview subjects were lying or telling the truth 82.5 percent of the time.

New 'thermal' approach to invisibility cloaking hides heat to enhance technology

Posted: 26 Mar 2012 10:35 AM PDT

In a new approach to invisibility cloaking, a team of French researchers has proposed isolating or cloaking objects from sources of heat -- essentially "thermal cloaking." This method taps into some of the same principles as optical cloaking and may lead to novel ways to control heat in electronics and, on an even larger scale, might someday prove useful for spacecraft and solar technologies.

Using Twitter to predict financial markets

Posted: 26 Mar 2012 08:33 AM PDT

Researchers have developed a model that uses data from Twitter to help predict the traded volume and value of a stock the following day.

'Noodle gels' or 'spaghetti highways' could become tools of regenerative medicine

Posted: 26 Mar 2012 08:24 AM PDT

Medicine's recipe for keeping older people active and functioning in their homes and workplaces — and healing younger people injured in catastrophic accidents — may include "noodle gels" and other lab-made invisible filaments that resemble uncooked spaghetti with nanoscale dimensions, a scientist has said.

Single molecules in a quantum movie

Posted: 25 Mar 2012 02:32 PM PDT

The quantum physics of massive particles has intrigued physicists for more than 80 years, since it predicts that even complex particles can exhibit wave-like behavior – in conflict with our everyday ideas of what is real or local.

European Space Agency cargo ship carries research and technology investigations to International Space Station

Posted: 23 Mar 2012 08:11 AM PDT

When the European Space Agency's third Automated Transfer Vehicle cargo ship arrives at the International Space Station on March 28, it will be packed with more than seven tons of supplies, including a mix of international partner research ranging from biology to education to physical science.

NASA measures impact of huge solar flare on Earth's atmosphere

Posted: 23 Mar 2012 08:11 AM PDT

A key NASA instrument that can directly measure the impact of solar events on Earth's upper atmosphere has weighed in on the huge flare that impacted Earth last week.
