Penn/CHOP study helps inform interventions for global road traffic injury crisis
A research team led by the University of Pennsylvania School of Nursing and Children's Hospital of Philadelphia's Center for Injury Research and Prevention worked with a major US multinational corporation to investigate employee perceptions of road risks and strategies to reduce road traffic injuries. This research was conducted in two Indian cities with some of the highest road traffic injury rates worldwide that are also centers for multinational corporations in the software and technology sectors.

Preventing blood clots with a new metric for heart function
Scientists from Johns Hopkins University and Ohio State University have discovered a new method for predicting those most at risk for thrombus, or blood clots, in the heart. The critical factor, they found, is the degree to which the mitral jet penetrates into the left ventricle of the heart. The findings were based on simulations performed using the Stampede supercomputer at the Texas Advanced Computing Center and validated using patient data.

Iowa State scientist receives grants to improve glacier-flow models, sea-level predictions
Iowa State's Neal Iverson, who has studied glaciers in Iceland and Norway, is working with an international team on two projects that aim to build more realistic computer models of glacier flow. The researchers hope to understand how glaciers will speed up over the next century as the climate warms. They say that could help them predict how much glaciers will contribute to the rise of sea levels.

Move over Bear Grylls! Academics build ultimate solar-powered water purifier
You've seen Bear Grylls turn foul water into drinking water with little more than sunlight and plastic. Academics added a third element -- carbon-dipped paper -- to create a highly efficient and inexpensive way to turn saltwater and contaminated water into potable water for personal use. The system could help address global drinking water shortages, especially in developing areas and regions affected by natural disasters.

Model shows female beauty isn't just sex appeal
Female beauty may have less to do with attracting the opposite sex than previously thought, at least in animals. Results of a mathematical modeling study suggest that romantic attention, by itself, is not enough to give attractive females an evolutionary edge over their plainer counterparts -- even when their good looks help them snag superior mates. For females, the benefits of beauty likely go beyond their success in the mating market, the model shows.

Researchers develop wearable, low-cost sensor to measure skin hydration
Researchers have developed a wearable, wireless sensor that can monitor a person's skin hydration to detect dehydration before it poses a health problem. The device is lightweight, flexible and stretchable and has already been incorporated into prototype devices that can be worn on the wrist or as a chest patch.

Both push and pull drive our galaxy's race through space
What is propelling the Milky Way's race through space? By 3-D mapping the flow of galaxies through space, researchers found that the Milky Way galaxy is speeding away from a large, previously unidentified region of low density. The study will appear in the forthcoming issue of Nature Astronomy.

Researchers develop label-free technique to image microtubules
Researchers in the Quantitative Light Imaging Laboratory at the Beckman Institute for Advanced Science and Technology at the University of Illinois have been able to use label-free spatial light interference microscopy (SLIM) and computer processing in order to image microtubules in an assay. The hollow tubular structures serve as the backbone of cells and help carry materials in the cell. Malfunctioning microtubules have been associated with various illnesses including cancer and Alzheimer's disease.

Researchers list reasons not to lick a toad
The cane toad, which overran Australia when introduced there, and Panama's iconic, endangered golden frog both belong to the family Bufonidae. Researchers combed through many research papers to compile all of the known chemicals produced by members of this amphibian family well known to practitioners of folk medicine. This is a first step toward the identification of new pharmaceuticals from amphibians at a time when human diseases are becoming alarmingly antibiotic resistant.

Tissue engineering advance reduces heart failure in model of heart attack
Researchers have grown heart tissue by seeding a mix of human cells onto a 1-micron-resolution scaffold made with a 3-D printer. The cells organized themselves in the scaffold to create engineered heart tissue that beats synchronously in culture. When the human-derived heart muscle patch was surgically placed onto a mouse heart after a heart attack, it significantly improved heart function and decreased the amount of dead heart tissue.
