How much water does the ocean have?
The calculation of variations in the sea level is relatively simple. It is by far more complicated to then determine the change in the water mass. view more (2009-11-13)
Swift XMM-Newton Satellites Tune Into a Middleweight Black Hole
While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by. view more (2009-11-11)
Sculptured materials allow multiple channel plasmonic sensors
Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculptured thin films. view more (2009-11-11)

Sensor biochips could aid in cancer diagnosis and treatment
It is very difficult to predict whether a cancer drug will help an individual patient: only around one third of drugs will work directly in a given patient. view more (2009-10-22)
Clemson researchers say algae key to mass extinctionss
Algae, not asteroids, were the key to the end of the dinosaurs, say two Clemson University researchers. Geologist James W. Castle and ecotoxicologist John H. Rodgers have published findings that toxin producing algae were a deadly factor in mass extinctions millions of years ago. view more (2009-10-20)
West Antarctic ice sheet may not be losing ice as fast as once thought
New ground measurements made by the West Antarctic GPS Network (WAGN) project, composed of researchers from The University of Texas at Austin, The Ohio State University, and The University of Memphis, suggest the rate of ice loss of the West Antarctic ice sheet has been slightly overestimated. view more (2009-10-20)
Killer algae a key player in mass extinctions
Supervolcanoes and cosmic impacts get all the terrible glory for causing mass extinctions, but a new theory suggests lowly algae may be the killer behind the world's great species annihilations. view more (2009-10-20)
The food-energy cellular connection revealed
Our body's activity levels fall and rise to the beat of our internal drums-the 24-hour cycles that govern fundamental physiological functions, from sleeping and feeding patterns to the energy available to our cells. view more (2009-10-16)

Ethnic background may be associated with diabetes risk
Fat and muscle mass, as potentially determined by a person's ethnic background, may contribute to diabetes risk, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). view more (2009-10-06)
Coral bleaching increases chances of coral disease
Mass coral bleaching has devastated coral colonies around the world for almost three decades. Now scientists have found that bleaching can make corals more susceptible to disease and, in turn, coral disease can exacerbate the negative effects of bleaching. view more (2009-10-02)
Overweight middle-aged women cut chances of enjoying healthy old age
Women who put on weight as they approach middle-age could reduce their chances of enjoying a healthy old age by up to 80%, according to research from the University of Warwick. view more (2009-09-30)
Help Students Think like Soil Scientists
Emphasizing cross-disciplinary concepts in teaching soil science courses, such as mass-volume relationships, can help undergraduates learn real-world, problem-solving skills that are crucial to their success in soil science careers. view more (2009-09-29)
Researchers identify new brain pathway for regulating weight and bone mass
Contrary to the prevailing view, the hormone leptin, which is critical for normal food intake and metabolism, appears to regulate bone mass and suppress appetite by acting mainly through serotonin pathways in the brain. view more (2009-09-24)
New multi-use device can shed light on oxygen intake
A fiber-optic sensor created by a team of Purdue University researchers that is capable of measuring oxygen intake rates could have broad applications ranging from plant root development to assessing the effectiveness of chemotherapy drugs. view more (2009-09-23)
Portable and precise gas sensor could monitor pollution and detect disease
