NASA's TRMM satellite sees deadly tornadic thunderstorms in Southeastern US

Sáb, 11/19/2011 - 16:25

Tornadoes are expected to accompany severe storms in the springtime in the U.S., but this time of year they also usually happen. When a line of severe thunderstorms associated with a cold front swept through the U.S. southeast on Nov. 16, TRMM collected rainfall data on the dangerous storms from space.

A corny turn for biofuels from switchgrass

Sáb, 11/19/2011 - 15:32

Many experts believe that advanced biofuels made from cellulosic biomass are the most promising alternative to petroleum-based liquid fuels for a renewable, clean, green, domestic source of transportation energy. Nature, however, does not make it easy. Unlike the starch sugars in grains, the complex polysaccharides in the cellulose of plant cell walls are locked within a tough woody material called lignin. For advanced biofuels to be economically competitive, scientists must find inexpensive ways to release these polysaccharides from their bindings and reduce them to fermentable sugars that can be synthesized into fuels.

MU researchers develop tool that saves time, eliminates mistakes in diabetes care

Sáb, 11/19/2011 - 15:32

In the fast-paced world of health care, doctors are often pressed for time during patient visits. Researchers at the University of Missouri developed a tool that allows doctors to view electronic information about patients' health conditions related to diabetes on a single computer screen. A new study shows that this tool, the diabetes dashboard, saves time, improves accuracy and enhances patient care.

Great Plains river basins threatened by pumping of aquifers

Sáb, 11/19/2011 - 14:31

Suitable habitat for native fishes in many Great Plains streams has been significantly reduced by the pumping of groundwater from the High Plains aquifer -- and scientists analyzing the water loss say ecological futures for these fishes are "bleak."

Old drugs find new target for treating brain tumor

Vie, 11/18/2011 - 16:37

Scientists at the University of California, San Diego School of Medicine and UC San Diego Moores Cancer Center, in collaboration with colleagues in Boston and South Korea, say they have identified a novel gene mutation that causes at least one form of glioblastoma (GBM), the most common type of malignant brain tumor.

Chalmers scientists create light from vacuum

Vie, 11/18/2011 - 14:35

Scientists at Chalmers have succeeded in creating light from vacuum -- observing an effect first predicted over 40 years ago. In an innovative experiment, the scientists have managed to capture some of the photons that are constantly appearing and disappearing in the vacuum.

Researchers pinpoint date and rate of Earth's most extreme extinction

Jue, 11/17/2011 - 21:31

It's well known that Earth's most severe mass extinction occurred about 250 million years ago. What's not well known is the specific time when the extinctions occurred. A team of researchers from North America and China have published a paper in Science which explicitly provides the date and rate of extinction.
