See-through transistor fabricated for future e-displays - Scientists have recently taken an important step toward the development of "see-through" flexible electronic displays by fabricating fully transparent, high-speed nanowire transistors. This piece of circuitry, the first transistor to demonstrate full transparency, could help turn ideas such as e-paper, displays on sunglasses, and maps on car windshields into a reality.

Unique Material May Allow Capacitors to Store More Energy - Imagine an electric car with the same acceleration capability as a gas-powered sports car, or ultrafast rechargeable "batteries" that can be recharged a thousand times more than existing conventional batteries. According to physicists at North Carolina State University, all of these things are possible, thanks to their research on a polymer - or plastic material - that when used as a dielectric in capacitors may allow the capacitors to store up to seven times more energy than those currently in use.

Prevent smoking to reduce risk of erectile dysfunction - Men who smoke cigarettes run an increased risk of experiencing erectile dysfunction, and the more cigarettes smoked, the greater the risk, according to a study by Tulane University researchers published in the American Journal of Epidemiology.

Obese girls less likely to attend college - Obese girls are half as likely to attend college as non-obese girls, according to a new study from The University of Texas at Austin.

Robots Clear Waterways of Deadly Mines - As it slowly moves in the shallow water along a beach, the robot splashes its fins like a small child playing in the surf. But the prototype device has a serious mission: destroying mines that could kill Marines and Navy SEALs as they come on shore. Such technology is considered the future of underwater bomb detection.

More fish oil, less vegetable oil, better for your health - Scientists have provided new evidence that using more fish oil than vegetable oil in the diet decreases the formation of chemicals called prostanoids, which, when produced in excess, increase inflammation in various tissues and organs. The results, by William L. Smith, Professor and Chair of Biological Chemistry at the University of Michigan, Ann Arbor, and colleagues, may help in designing new anti-inflammatory drugs with fewer side effects than the ones currently available.

People, animals behave better when watched: study - When people and animals know they are being watched, they behave in more positive ways toward others, according to a study published Thursday by the US magazine Science.

X-48B Blended Wing Body Research Aircraft Takes First Flight - NASA's Dryden Flight Research Center in Edwards, Calif., provided critical support for the first flight July 20 of the X-48B. The 21-foot wingspan, 500-pound remotely piloted test vehicle took off for the first time at 8:42 a.m. PDT and climbed to an altitude of 7,500 feet before landing 31 minutes later. The Boeing Co. of Seattle developed the blended wing body research aircraft.

MIT duo see people-powered 'Crowd Farm' - Two graduate students at MIT's School of Architecture and Planning want to harvest the energy of human movement in urban settings, like commuters in a train station or fans at a concert.

MySpace Finds 29,000 Sex Offenders - MySpace.com has found more than 29,000 registered sex offenders with profiles on the popular social networking Web site - more than four times the number cited by the company two months ago, officials in two states Tuesday.
