University of Minnesota ecologist David Tilman and several colleagues have discovered why a diversity of species controls ecosystem sustainability. Working with plots of prairie plants, the researchers found that what counts most is not the number of species per se, but the number of different ways species perform a variety of functions such as growing, cycling nutrients or producing seed.
LSU researcher Bob Carney was a member of a team of university scientists led by chief scientist Chuck Fisher of Pennsylvania State University who discovered what appears to be a new species of centipede-like worms that live on and within mounds of methane ice on the floor of the Gulf of Mexico.

Now that vaccination barrier zones are halting the northward spread of raccoon rabies in New York, Vermont and Ohio, Cornell University rabies-fighters are ready to extend the barriers across New Hampshire and Maine. Then the raccoon rabies vaccination could move southward, they predict, to turn back the viral disease in already-infected states.
The characteristic light flashes that summon male fireflies of the genus Photinus could come from female Photinus fireflies. Just as likely, the signaling females are from a different genus. The femmes fatales fireflies are luring unrelated males close enough to eat them. The males contain defensive chemicals that females need to repel predators, such as spiders.
BACK TO SCHOOL WITH NSF--The National Science Foundation funds an array of programs to improve the quality of science and math education for all Americans and to ensure a steady supply of the world's best-educated scientists, mathematicians and engineers. Roughly 20 percent of the NSF's $3.3 billion annual budget is allocated to its education and human resources programs. NSF's investment represents one-third of all federal spending on math and science education.
Scientists are one step closer to identifying one of the major toxins produced by the fish-killing organism Pfiesteria piscicida, which has been blamed for killing millions of fish along the East Coast. In a series of experiments completed earlier this month, researchers at North Carolina State University have for the first time successfully isolated and purified a water-soluble toxin component from Pfiesteria.
A new computing concept--patterned after successful space missions--may soon help UD researchers complete the blueprint for a supercomputer 1 million times more powerful than the most advanced PC now on the market.

The UNH Institute for the Study of Earth, Oceans, and Space will host the New England Regional Climate Change Impacts Workshop Sept. 3-5. This important regional gathering will bring together stakeholders interested in identifying climage change issues that impact their communities and possible local solutions for responding to global warming. The workshop is part of a federal initiative to define the nation's research agenda in the area of climate change.
University of New Hampshire researchers think some of the Earth's smallest organisms can tell us some big things about what we're doing to our planet. That's why Barry Rock, UNH associate professor of natural resources, and graduate student Katrina Maloney focus part of their research on lichen, which can be found on rocks, trees--even roof shingles.
In an effort to inform the 130,000 people living in New York's Adirondacks State Park where wolves may soon be sharing the landscape, the Wildlife Conservation Society (WCS) released a report today answering many of the commonly asked questions by residents about the big canines.

Using protons instead of photons, researchers have "photographed" the moving shock wave in an explosive's detonation. The technique has value for aiding in maintenance of the nation;s nuclear stockpile.
Drinkers of some espresso coffees who like a lot of foam can't be fussy about how quickly the foam disappears. That's because you can't have ultimate foaming and long-lasting foam at the same time, according to Dr. Manuel A. Coimbra and his student Fernando Nunes of the University of Aveiro in Portugal.

Evaluation of the workbook "Let's Talk About Living in a World With Violence," shows it can reduce aggression in children when the teacher is comfortable with the curriculum and integrates the material into other subjects.
Hundreds of people call Dr. JoAnn Burkholder's office at North Carolina State University each week seeking answers to questions about Pfiesteria piscicida, the toxic organism that, since 1991, has killed millions of fish in Mid-Atlantic coastal waters and, in some cases, been linked to human illnesses. Now, a new Web site may help them get the information they need with a few keystrokes and the click of a mouse.
Controlling odors from ponds holding industrial wastewater could be as easy as spreading a layer of barley straw over the water. Results from an ongoing demonstration at the American Crystal Sugar Co. beet-processing plant in East Grand Forks, Minn., have been so encouraging that the company is planning to use the technique next year three of its plants.
