Researchers think pink to produce green solar energy
When it comes to producing earth-friendly solar energy, pink may be the new green, according to Ohio State University researchers.
Mit team building robotic fin for submarines
Inspired by the efficient swimming motion of the bluegill sunfish, MIT researchers are building a mechanical fin that could one day propel robotic submarines.
Engineers ready a blueprint for a nanomechanical computer
If efforts now under way by a team of University of Wisconsin-Madison engineers pan out, the age of the nanomechanical computer may be at hand.
Two bacteria better than one in cellulose-fed fuel cell
No currently known bacteria that allow termites and cows to digest cellulose, can power a microbial fuel cell and those bacteria that can produce electrical current cannot eat cellulose. But careful pairing of bacteria can create a fuel cell that consumes cellulose and produces electricity, according to a team of Penn State researchers.
Miniature implanted devices could treat epilepsy, glaucoma
Purdue University researchers have developed new miniature devices designed to be implanted in the brain to predict and prevent epileptic seizures and a nanotech sensor for implantation in the eye to treat glaucoma.
Full-time sensors can detect bridge defects
Networks of small, permanently mounted sensors could soon check continuously for the formation of structural defects in I-beams and other critical structural supports of bridges and highway overpasses, giving structural engineers a better chance of heading off catastrophic failures.
Scuppering pirates improves internet audio
A new digital watermarking system not only protects music and media files from online pirates but also ensures that the quality for legitimate users is as good as it gets.
Beyond batteries: storing power in a sheet of paper
Researchers at Rensselaer Polytechnic Institute have developed a new energy storage device that easily could be mistaken for a simple sheet of black paper.
New technology has dramatic chip-cooling potential for future computers
Researchers have demonstrated a new technology using tiny "ionic wind engines" that might dramatically improve computer chip cooling, possibly addressing a looming threat to future advances in computers and electronics.
Gene regulation, not just genes, sets humans apart
The striking differences between humans and chimps aren't so much in the genes we have, which are 99 percent the same, but in the way those genes are used, according to new research from a Duke University team.

Undersea mission aids development of self-test for stress and fatigue
An undersea mission simulating the space environment will provide data for development of tools to quickly assess stress, fatigue and cognitive fitness in preparation for performing critical mission tasks.
Computers expose the physics of nascar
It's an odd combination of Navier-Stokes equations and NASCAR driving. Computer scientists at the University of Washington have developed software that is incorporated in new technology allowing television audiences to instantaneously see how air flows around speeding cars.
Test of through-the-earth communication system exceeds expectations
Rigorous testing at the Lake Lynn Experimental Mine last month proved the viability of Vital Alert Technologies' system for emergency warning, evacuation, and rescue communications.
Metasearch engine digs deeper, faster for news
Are you getting all the news you need from Internet search engines that you use to find the latest headlines? Maybe not, said University of Illinois at Chicago computer science professor Clement Yu, who has devised software that finds a world of news stories that big search engines either overlook or do not deliver in a timely manner.
Rocketing into hiperspace
Engineers at the University of California, San Diego have constructed the highest-resolution computer display in the world – with a screen resolution up to 220 million pixels.
Mit's 'clutter detector' could cut confusion
The danger of clutter--especially on a visual screen--is that it causes confusion that affects how well we perform tasks. To that end, visual clutter is a challenge for fighter pilots picking out a target, for people seeking important information in a user interface, and for web site and map designers, among others.
New microbial fuel cell design boosts electricity production
Biological engineers at Oregon State University have designed a microbial fuel cell that is capable of generating about 10 times more electricity than previously possible from an air cathode microbial fuel cell of the same size.
Cow-powered fuel cells grow smaller, mightier
Cows could one day help to meet the rise in demand for alternative energy sources, say Ohio State University researchers that used microbe-rich fluid from a cow to generate electricity in a small fuel cell.
Researchers learn to control nanotube dimensions
Moving beyond carbon nanotubes, researchers are developing insights into a remarkable class of tubular nanomaterials that can be produced in water with a high degree of control over their diameter and length. Based on metal oxides in combination with silicon and germanium, such single-walled inorganic nanotubes could be useful in a range of nanotechnology applications that require precise control over nanotube dimensions.
Engineers perfecting hydrogen-generating technology
Researchers at Purdue University have further developed a technology that could represent a pollution-free energy source for a range of potential applications, from golf carts to submarines and cars to emergency portable generators.
