Wii key to helping kids balance (May 21, 2011) -- By cleverly linking five Wii Balance Boards, a team of university undergraduates has combined the appeal of a video game with the utility of a computerized motion-tracking system that can enhance patient progress. ... > full story

First macro-scale thin-film solid-oxide fuel cell: Strong, nanostructured membrane enables scaling for clean-energy applications (May 21, 2011) -- Materials scientists have demonstrated the first macro-scale thin-film solid-oxide fuel cell. While SOFCs have previously worked at the micro-scale, this is the first time any research group has overcome the structural challenges of scaling the technology up to a practical size with a proportionally higher power output. ... > full story

Pharmacies' software systems miss potentially dangerous interactions, study finds (May 21, 2011) -- Only 28 percent of pharmacies' clinical decision support software systems -- the computer programs that are in place to alert pharmacists to possible medication problems -- correctly identified potentially dangerous drug-drug interactions, according to a new study. ... > full story

Artificial tissue promotes skin growth in wounds (May 21, 2011) -- Improved tissue grafts designed by scientists that promote vascular growth could hasten healing, encourage healthy skin to invade the wounded area and reduce the need for surgeries. ... > full story

Smooth single-molecule layers of materials: Expanding the degrees of surface freezing (May 21, 2011) -- As part of the quest to form perfectly smooth single-molecule layers of materials for advanced energy, electronic, and medical devices, researchers have discovered that the molecules in thin films remain frozen at a temperature where the bulk material is molten. ... > full story

Radio telescopes capture best-ever snapshot of black hole jets (May 20, 2011) -- An international team, using radio telescopes located throughout the Southern Hemisphere, has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy. ... > full story

Buying 'legal highs' from the Internet is risky business (May 20, 2011) -- Many drugs sold as "legal highs" on the Internet do not contain the ingredients they claim. Some instead contain controlled substances and are illegal to sell over the internet. These are findings of a doctor, who bought a range of tablets from different websites to see what each contained. ... > full story

Researchers create nanopatch for the heart (May 20, 2011) -- Engineers have a promising new approach to treating heart-attack victims. The researchers created a nanopatch with carbon nanofibers and a polymer. In laboratory tests, natural heart-tissue cell density on the nanoscaffold was six times greater than the control sample, while neuron density had doubled. ... > full story

Laser modules in matchbox size (May 20, 2011) -- Miniaturized laser beam sources which are suitable for a variety of applications, from material processing to display technology have recently been developed. ... > full story

Record efficiency of 18.7 percent for flexible solar cells on plastics, Swiss researchers report (May 20, 2011) -- Swiss scientists have further boosted the energy conversion efficiency of flexible solar cells made of copper indium gallium (di)selenide (also known as CIGS) to a new world record of 18.7 percent -- a significant improvement over the previous record of 17.6 percent achieved by the same team in June 2010. The measurements have been independently certified. ... > full story

Wireless sensor network monitors microclimate in the forest (May 20, 2011) -- During a forest monitoring operation, forestry scientists measure various environmental values. This is how they obtain indications about how the forests are changing and what can be done to preserve them. However, installing and maintaining the wired measuring stations is complex: Researchers developed a wireless alternative. ... > full story

It's not easy being green: Scientists grow understanding of how photosynthesis is regulated (May 19, 2011) -- The seeds sprouting in your spring garden may still be struggling to reach the sun. If so, they are consuming a finite energy pack contained within each seed. Once those resources are depleted, the plant cell nucleus must be ready to switch on a "green" photosynthetic program. Researchers recently showed a new way that those signals are relayed. ... > full story
