Lincoln, Neb., May 15, 2014 -- In many rural communities hard hit by decades of population declines, young men increasingly outnumber young women, a new study of Kansas and Nebraska census data shows.

In places with 800 or fewer residents, the proportion of young men increased by an average of nearly 40 percent as people went from their teens to their 20s.

Using modern weather satellites to monitor rainfall has become a robust, widely practiced technique. However, establishing a reliable context for relating space-based rainfall observations to current and historical ground-based rainfall data has been difficult.

The West Antarctic Ice Sheet, which holds enough water to raise global seas by several feet, is thinning. Scientists have been warning of its collapse, based on theories, but with few firm predictions or timelines.

Scientists have discovered new evidence to suggest that lightning on Earth is triggered not only by cosmic rays from space, but also by energetic particles from the Sun.

University of Reading researchers found a link between increased thunderstorm activity on Earth and streams of high-energy particles accelerated by the solar wind, offering compelling evidence that particles from space help trigger lightning bolts.

This past November, NASA launched the Mars Atmosphere and Volatile Evolution (MAVEN) mission in the hope of understanding how and why the planet has been losing its atmosphere over billions of years.

One instrument aboard the spacecraft will study a special component of the Martian atmosphere to help solve this mystery. By studying ions, or small electrically charged particles, in and above the Red Planet's tenuous atmosphere, the Solar Wind Ion Analyzer will help answer why Mars has gradually lost much of its atmosphere, developing into a frozen, barren planet.

The ocean is an increasingly industrialized space. Shipping, fishing, and recreational vessels, oil and gas exploration and other human activities all increase noise levels in the ocean and make it more difficult for marine mammals to hear and potentially diminish their range of hearing.

"Hearing is the main way marine mammals find their way around the ocean," said Aran Mooney, a biologist at Woods Hole Oceanographic Institution (WHOI). It's important to know whether and to what extent human activity is negatively impacting them.

The Continuous Electron Beam Accelerator Facility (CEBAF) at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility has achieved the final two accelerator commissioning milestones needed for approval to start experimental operations following its first major upgrade.

AUGUSTA, Ga. – While it seems like restoring blood flow to an injured leg would be a good thing, it can actually cause additional damage that hinders recovery, researchers say.

Ischemia reperfusion injury affects nearly two million Americans annually with a wide variety of scenarios that temporarily impede blood flow – from traumatic limb injuries, to heart attacks, to donor organs, said Dr. Babak Baban, immunologist at the Medical College of Georgia and College of Dental Medicine at Georgia Regents University.

When a massive star collapses under its own gravity during a supernova explosion it forms either a neutron star or black hole. Magnetars are an unusual and very exotic form of neutron star. Like all of these strange objects they are tiny and extraordinarily dense — a teaspoon of neutron star material would have a mass of about a billion tonnes — but they also have extremely powerful magnetic fields. Magnetar surfaces release vast quantities of gamma rays when they undergo a sudden adjustment known as a starquake as a result of the huge stresses in their crusts.

Virginia Tech has updated results of its adult football helmet ratings, which are designed to identify key differences between the abilities of individual helmets to reduce the risk of concussion.

Men who have been incarcerated and released are more than twice as likely to die prematurely as those who have not been imprisoned, according to a new study published by Georgia State University criminologist William Alex Pridemore.

Firefighters are currently battling the Signal Fire in the Gila National Forest in New Mexico. The fire was reported by the Signal Peak Lookout Tower Sunday (May 11) in the afternoon and is located approximately 15 miles north of Silver City. It is currently estimated to be 4,700 acres. The Southwest Area Incident Management Team assumed command of the fire Monday at 6:00 p.m. The cause of the fire is thought to be human either a careless camper or arson, but the investigation is still ongoing. Residents in the vicinity of Signal Peak have evacuated.

A gas giant has been added to the short list of exoplanets discovered through direct imaging. It is located around GU Psc, a star three times less massive than the Sun and located in the constellation Pisces. The international research team, led by Marie-Ève Naud, a PhD student in the Department of Physics at the Université de Montréal, was able to find this planet by combining observations from the the Gemini Observatories, the Observatoire Mont-Mégantic (OMM), the Canada-France-Hawaii Telescope (CFHT) and the W.M. Keck Observatory.

National Science Foundation- (NSF) funded researchers at the University of Washington have concluded that Antarctica's fast-moving Thwaites Glacier will likely disappear in a matter of centuries, potentially raising sea level by more than a half-a-meter (two feet).

Data gathered by NSF-funded airborne radar, detailed topography maps and computer modeling was used to make the determination.

Teenagers and their foster families often say they don't feel connected and have trouble communicating, but few resources exist that nurture their bonding. In a research paper being published in the June issue of Children and Youth Services Review, researchers affiliated with the University of Washington's School of Social Work describe how they tailored a parenting program known to improve communication in non-foster families for use in foster families.
