Supervolcano eruption -- in Sumatra -- deforested India 73,000 years ago
A new study provides "incontrovertible evidence" that the volcanic super-eruption of Toba on the island of Sumatra about 73,000 years ago deforested much of central India, some 3,000 miles from the epicenter, researchers report.   view more (2009-11-24)

New tool for helping pediatric heart surgery
A team of researchers at the University of California, San Diego and Stanford University has developed a way to simulate blood flow on the computer to optimize surgical designs.   view more (2009-11-24)

Generating electricity from air flow
A group of researchers at the City College of New York is developing a new way to generate power for planes and automobiles based on materials known as piezoelectrics, which convert the kinetic energy of motion into electricity.   view more (2009-11-23)

Measuring and modeling blood flow in malaria
When people have malaria, they are infected with Plasmodium parasites, which enter the body from the saliva of a mosquito, infect cells in the liver, and then spread to red blood cells.   view more (2009-11-23)

On the crest of wave energy
The ocean is a potentially vast source of electric power, yet as engineers test new technologies for capturing it, the devices are plagued by battering storms, limited efficiency, and the need to be tethered to the seafloor.   view more (2009-11-20)

'No muss, no fuss' miniaturized analysis for complex samples developed
The goal of an integrated, miniaturized laboratory analysis system, also known as a "lab-on-a-chip," is simple: sample in, answer out.   view more (2009-11-18)

Iowa State scientist develops lab machine to study glacial sliding related to rising sea levels
Neal Iverson opened his laboratory's walk-in freezer and said the one-of-a-kind machine inside could help scientists understand how glaciers slide across their beds. And that could help researchers predict how glaciers will react to climate change and contribute to rising sea levels.    view more (2009-11-11)

Cave Study Links Climate Change to California Droughts
California experienced centuries-long droughts in the past 20,000 years that coincided with the thawing of ice caps in the Arctic.   view more (2009-11-11)

Antarctica glacier retreat creates new carbon dioxide store
Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula.   view more (2009-11-10)

New Transparent Insulating Film Could Enable Energy-Efficient Displays
Johns Hopkins materials scientists have found a new use for a chemical compound that has traditionally been viewed as an electrical conductor, a substance that allows electricity to flow through it.   view more (2009-11-10)

Ice cream researchers making sweet strides with 'functional foods'
A comfort food, a tasty treat, an indulgence - ice cream conjures feelings of happiness and satisfaction for millions. Ice cream researchers at the University of Missouri have discovered ways to make ice cream tastier and healthier and have contributed to ice cream development and manufacturing for more than a century.   view more (2009-11-10)

Past climate of the northern Antarctic Peninsular informs global warming debate
The seriousness of current global warming is underlined by a reconstruction of climate at Maxwell Bay in the South Shetland Islands of the Antarctic Peninsula over approximately the last 14,000 years, which appears to show that the current warming and widespread loss of glacial ice are unprecedented.    view more (2009-11-09)

New insight into predicting cholera epidemics in the Bengal Delta
Cholera, an acute diarrheal disease caused by the bacterium Vibrio cholerae, has reemerged as a global killer. Outbreaks typically occur once a year in Africa and Latin America. But in Bangladesh the epidemics occur twice a year - in the spring and again in the fall.   view more (2009-11-05)

Texas A&M prof to predict weather on Mars
Is there such a thing as "weather" on Mars? There are some doubts, considering the planet's atmosphere is only 1 percent as dense as that of the Earth.   view more (2009-11-05)

Materials scientists find better model for glass creation
Harvard materials scientists have come up with what they believe is a new way to model the formation of glasses, a type of amorphous solid that includes common window glass.   view more (2009-11-05)

New scientific study indicates that eating quickly is associated with overeating
According to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM), eating a meal quickly, as compared to slowly, curtails the release of hormones in the gut that induce feelings of being full.   view more (2009-11-04)

Hard Rain: Pitt-led Researchers Create Nano-Particle Coating to Prevent Freezing Rain Buildup on Roads, Power Lines
Preventing the havoc wrought when freezing rain collects on roads, power lines, and aircrafts could be only a few nanometers away.   view more (2009-10-30)

Mirinae intensifying while moving away from the northern Marianas
Typhoon Mirinae is moving west and away from the Northern Marianas Islands on a track to a landfall in the Philippines by the weekend. As Mirinae has moved west, NASA's infrared and microwave satellite imagery have seen high, strong thunderstorm development, and a developing eye.   view more (2009-10-29)

The pain of torture can make the innocent seem guilty
The rationale behind torture is that pain will make the guilty confess, but a new study by researchers at Harvard University finds that the pain of torture can make even the innocent seem guilty.   view more (2009-10-27)

Volcanoes played pivotal role in ancient ice age, mass extinction
Researchers here have discovered the pivotal role that volcanoes played in a deadly ice age 450 million years ago. Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere. When they stopped erupting, Earth's climate was thrown off balance, and the ice age began.   view more (2009-10-27)
