As sea levels rise due to climate change, so do the global hazards and potential devastating damages from tsunamis, according to a new study by a partnership that included Virginia Tech.

Even minor sea-level rise, by as much as a foot, poses greater risks of tsunamis for coastal communities worldwide.

CORVALLIS, Ore. - Timber harvested illegally under fraudulent permits is undercutting conservation efforts in the Brazilian Amazon, new research by an international collaboration shows.

The findings represent a troublesome counterpunch to an overall decline in deforestation rates in the region and indicate high-value timber species such as ipe? may be at risk of overexploitation.

A car accident leaves an aging patient with severe muscle injuries that won't heal. Treatment with muscle stem cells from a donor might restore damaged tissue, but doctors are unable to deliver them effectively. A new method may help change this.

The open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide in winter than previously believed, a new study has found. Researchers conducting the study used data gathered over several winters by an array of robotic floats diving and drifting in the Southern Ocean around the southernmost continent.

Scientists in Norfolk, VA (USA) have developed a new method of making collagen microfibres, which could have applications in research, medical devices and clinical treatments ranging from ligament damage to skin burns.

While collagen fibre manufacturing methods such as electrospinning and extrusion exist for biomedical applications, they have seen limited clinical success. This is partially due to challenges of scalability, cost, and complexity.

New research published in The Journal of Physiology highlights how exercise could help people exposed to extreme temperatures protect themselves from the cold. This could be useful for people who live and work in very cold conditions.

RIVERSIDE, Calif. -- A team of astronomers led by George Becker at the University of California, Riverside, has made a surprising discovery: 12.5 billion years ago, the most opaque place in the universe contained relatively little matter.

About 422 million people around the world, including more than 30 million Americans, have diabetes. Approximately ninety percent of them have type 2 diabetes. People with this condition cannot effectively use insulin, a hormone made by the pancreas that helps the body turn blood sugar (glucose) into energy.

Most of the Eastern half of the United States had rainfall during the past week. Some parts of the country experienced heavy rainfall that resulted in flash floods and various other problems. NASA added up that rainfall using satellite data and a program called IMERG to provide a look at the amount of rainfall along the eastern U.S.

COLUMBUS, Ohio - Young black males feel less safe when they go to neighborhoods with a larger white population than occurs in areas they normally visit, a new study suggests.

Researchers gave 506 black youths in Columbus smartphones that tracked their locations for a week and asked the participants to rate how safe they felt (among other questions) five times per day.
