Wireless power could cut cord for patients with implanted heart pumps Posted: 12 Jul 2011 01:28 PM PDT A new system to send electricity over short distances has been shown to reliably power a mechanical heart pump. The system could free patients from being tethered to a battery or external power source, lowering their chance of infection and improving their quality of life.

Supramolecules get time to shine: Technique reveals interactions between nanotubes, photoluminescent materials Posted: 12 Jul 2011 12:22 PM PDT What looks like a spongy ball wrapped in strands of yarn -- but a lot smaller -- could be key to unlocking better methods for catalysis, artificial photosynthesis or splitting water into hydrogen, according to chemists who have created a platform to analyze interactions between carbon nanotubes and a wide range of photoluminescent materials.

Scientists model physics of a key dark-energy probe: Simulations improve characterization of cosmology’s 'standard ruler’ Posted: 12 Jul 2011 11:30 AM PDT Researchers are leveraging powerful supercomputers to investigate one of the key observational probes of "dark energy." The project focuses on simulations created on Ohio Supercomputer Center systems to simplify and better characterize a subtle dark-matter clustering feature. The new model allows cosmologists to gain a more accurate understanding of certain aspects of large-scale structure, such as the effect of the expansion of the universe on the growth of density fluctuations.

Computer learns language by playing games Posted: 12 Jul 2011 10:33 AM PDT Researchers have created a system that allows a computer to learn to play a computer game by learning the language required to read the manual.

New technology allows lenses to change color rapidly Posted: 12 Jul 2011 06:40 AM PDT A chemist has developed new technology that allows lenses to change color instantly using an electric current triggered by a stimulus, such as light.

Innovative system for producing carpets Posted: 12 Jul 2011 06:38 AM PDT In Europe 700 million square meters of carpets are produced each year, and in the United States the volume is ten times higher. Researchers have now developed an enzyme-based biological technology that paves the way for manufacturing carpets that are much lighter, sustainable, biodegradable, and 100% recyclable. A wool carpet manufactured using this innovative system is a completely natural and biodegradable product. At the end of its useful life the entire product can be shredded and turned into organic material, which can then be used, for example, as fertilizer for growing plants.

Intelligent street lighting saves up to 80% on energy Posted: 12 Jul 2011 06:36 AM PDT Scientists in the Netherlands are currently testing an intelligent street lighting system which uses up to 80% less electricity than the current systems and is also cheaper to maintain.
