Emergency department visits from beach injuries are common, study finds

Injuries to people swimming at the beach are common and severe, according to an ongoing study by the Delaware Sea Grant College Program and Beebe Medical Center.

A total of 1,121 injuries requiring emergency department treatment were recorded in Delaware during the past three summers for patients hurt by ocean waves. Injuries range from simple sprains and strains to extremity fractures, blunt organ trauma and fractures of the cervical spine. There were three fatalities attributed to surf zone injuries during the study period. The most common ailments were broken collarbones, dislocated and separated shoulders, neck pain, and ankle and knee sprains. (more…)

PASADENA, Calif. — NASA’s Mars rover Curiosity is driving toward a flat rock with pale veins that may hold clues to a wet history on the Red Planet. If the rock meets rover engineers’ approval when Curiosity rolls up to it in coming days, it will become the first to be drilled for a sample during the Mars Science Laboratory mission.

The size of a car, Curiosity is inside Mars’ Gale Crater investigating whether the planet ever offered an environment favorable for microbial life. Curiosity landed in the crater five months ago to begin its two-year prime mission. (more…)

PASADENA, Calif. – Scientists with NASA’s Cassini mission have spotted what appears to be a miniature, extraterrestrial likeness of Earth’s Nile River: a river valley on Saturn’s moon Titan that stretches more than 200 miles (400 kilometers) from its “headwaters” to a large sea. It is the first time images have revealed a river system this vast and in such high resolution anywhere other than Earth.

Scientists deduce that the river, which is in Titan’s north polar region, is filled with liquid hydrocarbons because it appears dark along its entire length in the high-resolution radar image, indicating a smooth surface. (more…)

Water Flowing Through Ice Sheets Accelerates Warming, Could Speed Up Ice Flow, Says New Study

Melt water flowing through ice sheets via crevasses, fractures and large drains called moulins can carry warmth into ice sheet interiors, greatly accelerating the thermal response of an ice sheet to climate change, according to a new study involving the University of Colorado at Boulder.

The new study showed ice sheets like the Greenland Ice Sheet can respond to such warming on the order of decades rather than the centuries projected by conventional thermal models. Ice flows more readily as it warms, so a warming climate can increase ice flows on ice sheets much faster than previously thought, said the study authors. (more…)
