Climate researchers are warning that efforts to reduce air pollution could, if not well designed, make global warming worse. Limiting emissions of man-made nitrogen oxides, a strategy to control ozone in the lower atmosphere, would result in increased methane abundance and lead to additional greenhouse warming.
Have the cows gone mad? Are the ice caps melting? Is a woman raped every nine seconds? If you answered yes to all of these questions, it means you've been listening to the media. If you answered no, you've been listening to the experts.

After a winter of unusually heavy snow, several rivers may surge out of their banks across North Dakota and Minnesota in the next week and across northern New England later this month. Experts and Web sites from the University Corporation for Atmospheric Research help shed light on America's deadly flood and flash-flood risks.
Scientists have long predicted that tuna, with their highly streamlined body and elevated internal temperatures, are equipped with a "high performance" muscle system. Tuna, researchers suspected, power their swimming by projecting muscle force from the mid-body, where the muscle is concentrated, back to the tail, which essentially acts as a natural, thrust-producing hydrofoil.
Scientists studying an Amazonian watershed have found strikingly different seasonal patterns of nutrient cycling than elsewhere in the world.
Inspired by nature's own building blocks, Purdue University researchers are using the same principle that makes DNA strands link together to create tiny structures that may someday be used to manufacture molecular wires and other components for use in nanometer-sized electronic devices.
Scientists have long known that plants and certain microorganisms use an important protein to convert carbon dioxide from the air into useable carbon. Now, researchers investigating green sulfur bacteria - microbes capable of breaking down sulfur compounds - have uncovered a new link they believe to be an ancestor of that carbon-fixing protein.
Scientist Tullis Onstott of Princeton University will speak on subsurface microbial communities that live deep within the gold mines of South Africa at the National Science Foundation on April 24.
Two tests have been conducted to demonstrate the feasibility of burning a combination of subbituminous coal and sunflower hulls to produce heat for the campus at the University of North Dakota. What was once considered a waste material can now be used to produce clean energy from an alternative, renewable fuel source.
Researchers at The University of Texas at Austin have used a new form of laser technology called single molecule spectroscopy to make important contributions to understanding the motion of molecules in supercooled liquids, a problem of interest to scientists for more than half a century.
Using a novel detector attached to the submarine Alvin, a research team led by University of Delaware marine scientists has determined that water chemistry controls the location and distribution of two species of weird worms that inhabit deep-sea hydrothermal vent sites.
Although the Human Genome Project grabs headlines, perhaps the bigger story in biology will be in plant and animal genomics: the first benefits to society are likely to come from these areas, where it is generally easier and less controversial to utilize genetic information, according to the director of Purdue University's Office of Agricultural Research Programs.
