Vibration may help heal chronic wounds

Vibration may help heal chronic wounds

Wounds may heal more quickly if exposed to low-intensity vibration, report researchers at the University of Illinois at Chicago.

The finding, in mice, may hold promise for the 18 million Americans who have type 2 diabetes, and especially the quarter of them who will

Study finds astronauts' hearts become more spherical in space

New findings from a study of 12 astronauts show the heart becomes more spherical when exposed to long periods of microgravity in space, a change that could lead to cardiac problems, according to research to be presented at the American College of Cardiology's 63rd

SLAC, Stanford study identifies long-sought path toward engineering materials for super-efficient nanoelectronics

Scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have discovered a potential way to make

High-tech materials purify water with sunlight

High-tech materials purify water with sunlight

Sunlight plus a common titanium pigment might be the secret recipe for ridding pharmaceuticals, pesticides and other potentially harmful pollutants from drinking water. Scientists combined several high-tech components to make an easy-to-use water purifier that could

Volcanoes helped species survive ice ages

Volcanoes helped species survive ice ages

An international team of researchers has found evidence that the steam and heat from volcanoes and heated rocks allowed many species of plants and animals to survive past ice ages, helping scientists understand how species respond to climate change.

Airborne radar demonstrates ability to foresee sinkholes

Airborne radar demonstrates ability to foresee sinkholes

New analyses of NASA airborne radar data collected in 2012 reveal the radar detected indications of a huge sinkhole before it collapsed and forced evacuations near Bayou Corne, Louisiana, that year.

The findings suggest such radar data, if collected routinely from

Hubble telescope witnesses asteroid's mysterious disintegration

Hubble telescope witnesses asteroid's mysterious disintegration

NASA's Hubble Space Telescope has recorded the never-before-seen break-up of an asteroid into as many as 10 smaller pieces.

Fragile comets, comprised of ice and dust, have been seen falling apart as they near the sun, but nothing like this has ever before been

Increase in Arctic cyclones linked to climate change, new study shows

Increase in Arctic cyclones linked to climate change, new study shows

Winter in the Arctic is not only cold and dark, it is also storm season when hurricane-like cyclones traverse the northern waters from Iceland to Alaska. These cyclones are characterized by strong localized drops in sea level pressure, and as Arctic-wide decreases in

Volcanoes, including Mt. Hood, can go from dormant to active quickly

Volcanoes, including Mt. Hood, can go from dormant to active quickly

A new study suggests that the magma sitting 4-5 kilometers beneath the surface of Oregon's Mount Hood has been stored in near-solid conditions for thousands of years, but that the time it takes to liquefy and potentially erupt is surprisingly short – perhaps
