In a counter-intuitive finding, new research from North Carolina State
University shows that a species of shellfish widely consumed in the
Pacific
over the past 3,000 years has actually increased in size, despite—and
possibly
because of—increased human activity in the area.

By
dipping plain cotton cloth in a high-tech broth full of silver
nanowires and carbon nanotubes, Stanford researchers have developed a
new high-speed, low-cost water purification filter. Instead of
physically trapping bacteria as most existing filters do, the new filter
relies on the power of electricity.

Temperatures
of minus 1.8°C should be enough to freeze any fish: the freezing point
of fish blood is about minus 0.9°C. But some species keep moving at
these temperatures, and researchers in the U.S. and Germany have used
terahertz spectroscopy to unravel the underlying mechanism that allow
anti-freeze proteins work better than any household antifreeze.

An international collaboration led by a University of Pennsylvania anthropologist has shown that environmental factors, like temperature and light, play as much of a role in the activity of traditionally nocturnal monkeys as the circadian rhythm that regulates periods of sleep and wakefulness.

In 1998, Charlie Kerfoot discovered a "doughnut" of phytoplankton circulating in Lake Michigan, helping to feed the lake's famous fishery. Just 12 later, the doughnut is disappearing, and Kerfoot fears that the lake's ecosystem will crash, taking with it much of the fish biomass.

NASA satellite data has noticed that Tropical Storm Fiona is getting "longer." That is, the storm is elongating in almost a north-south direction, indicating that she's weakening and may not make it through the weekend. Meanwhile, forecasters are watching two other areas for development...

Phosphorus, a mineral element found in rocks and bone, is a critical ingredient in fertilizers, pesticides, detergents and other industrial and household chemicals. Once phosphorus is mined from rocks, getting it into these products is hazardous and expensive, and chemists have been...

Three NASA aircraft carrying 15 instruments are busy criss-crossing Earl as part of the agency's Genesis and Rapid Intensification Processes mission, or GRIP, which continues through Sept. 30. GRIP is designed to help improve our understanding of how hurricanes such as Earl form and...

Afla-Guard, a biological control used to thwart the growth of fungi on peanuts, can be used on corn as well, according to a study by US Department of Agriculture scientists who helped develop it. After extensive study and research trials in Texas, Afla-Guard was registered by the US...

A new study led by a Stanford researcher shows that more than 80 percent of the new farmland created in the tropics between 1980 and 2000 came from felling forests, which sends carbon into the atmosphere and drives global warming. But the research team also noted that big agribusiness has...

A UCLA team led by Xiangfeng Duan has developed a new fabrication process for high-speed graphene transistors using a nanowire as the self-aligned gate. This new technique does not produce any appreciable defects in the graphene during fabrication, so the carrier mobility is retained....

Hurricane Earl is still a powerful category four hurricane on the Saffir-Simpson Scale as it approaches the North Carolina coast today. NASA's Tropical Rainfall Measuring Mission (TRMM) satellite observed the high rates rain was falling within Earl, in some areas more than 2 inches per...
