Physicists reveal striking similarities in sporting performance

Finding the similarities between volleyball and snooker may seem quite tricky. However, a group of physicists have found that the spread of scores, otherwise known as distribution, across their ranking systems are almost identical.

Research uncovers path to defect-free thin films

Scientists have discovered a strain relaxation phenomenon in cobaltites that has eluded researchers for decades and may lead to advances in fuel cells, magnetic sensors and a host of energy-related materials.

New Material Will Finally Let Us Convert Waste Heat to Electricity | 80beats

If you’re reading this with a laptop sitting on your legs, you might have noticed that computers tend to warm up as they work, turning electrical energy into thermal energy. In fact, two-thirds of all the energy we use is lost as waste heat. Maybe, instead of just using the heat from your computer to keep your lap toasty, we should be harnessing that heat by turning it back into electricity. But the thermoelectric materials that convert thermal to electrical energy aren’t very good at their job.

Optical waveguide connects semiconductor chips: Photonic wire bond transmits data in the terabit range

A team of researchers has succeeded in developing a novel optical connection between semiconductor chips. "Photonic wire bonding" reaches data transmission rates in the range of several terabits per second and is suited perfectly for production on the industrial scale. In the future, this technology may be used in high-performance emitter-receiver systems for optical data transmission and, thus, contribute to reducing energy consumption of the internet.

Computer simulations for multiscale systems can be faster, better, more reliable

University of Oregon scientists have found a way to correctly reproduce not only the structure but also important thermodynamic quantities such as pressure and compressibility of a large, multiscale system at variable levels of molecular coarse-graining.

NASA Selects Teachers to Fly Student Experiments in Reduced Gravity Aircraft

Teachers from NASA Explorer Schools have been selected to receive the 2012 School Recognition Award for their contributions to science, technology, engineering and mathematics education.
