A team of researchers, led by NASA and Columbia University scientists, found airborne, microscopic, black- carbon (soot) particles are even more plentiful around the world, and contribute more to climate change, than was previously assumed by the Intergovernmental Panel of Climate Change (IPCC).
The researchers concluded if these soot particles are not reduced, at least as rapidly as light-colored pollutants, the world could warm more quickly.
The findings appear in the latest issu
Penn State environmental engineers estimate, based on tests with wastewater from small Pennsylvania food processors, that typical large food manufacturers could use their starch-rich wastewater to produce hydrogen gas worth close to $5 million or more each year. They present their findings today at the 103rd General Meeting of the American Society for Microbiology.

Feeding birds display similar habits to human consumers shopping for food, according to research published in the current edition of the Proceedings of the Royal Society.
A two-year study has discovered it is possible to influence hummingbirds’ choice of food by changing the options available to them, in the same way supermarkets can manipulate customers’ preferences by clever positioning of products.

Using a laser range-finder, neurobiologists have scanned real-life scenes to gather millions of distance measurements to surfaces in each scene — analyzing the mass of data to explain a series of long-known but little-understood quirks in how people judge distances.
The measurements reveal, for example, that the tendency of people to estimate the distance of isolated objects as being six to 12 feet away arises because that is the average distance of actual objects and surfaces in the visual
Scientists at The Scripps Research Institute (TSRI) have designed a new way to make vaccines against drugs of abuse that could become a valuable tool for treating addiction by helping the body clear the drug from the bloodstream.
The latest vaccine they created using this approach induces the body to clear nicotine.
“These new vaccines greatly suppress the reinforcing aspects of the drug,” says principal investigator Kim D. Janda, Ph.D. “Blocking it before it gets to the brain–th
USC researchers find ways to improve effectiveness against tumors
Researchers from the Keck School of Medicine of the University of Southern California have isolated a protein fragment derived from the cancer immunotherapy drug interleukin 2 (IL-2) that seems to enhance the uptake of chemotherapeutic agents into tumors.
In fact, says Alan Epstein, M.D., Ph.D., professor of pathology at the Keck School of Medicine, when this patented protein fragment is attached to a tumor-ta
