As climate change is credited as one of the main drivers behind soaring food prices, the Global Crop Diversity Trust is undertaking a major effort to search crop collections—from Azerbaijan to Nigeria—for the traits that could arm agriculture against the impact of future changes. Traits, such as drought resistance in wheat, or salinity tolerance in potato, will become essential as crops around the world have to adapt to new climate conditions.

Los Angeles, London, New Delhi, Singapore and Washington DC – (September 17, 2008) Mangled bodies, gunfire, high-speed chases and injured children are just a few events witnessed by police officers and soldiers serving in dangerous hot spots around the world. These traumas take a high toll on the police officers and soldiers, who suppress human emotions to get the job done and can be reluctant to share their experiences in an effort to spare others from their ordeals, according to a September Police Quarterly article (published by SAGE).

WASHINGTON -- The importance of research in solving many of our national challenges, including economic ones, was emphasized today in a new report titled SCIENCE AND TECHNOLOGY FOR AMERICA'S PROGRESS: ENSURING THE BEST PRESIDENTIAL APPOINTMENTS IN THE NEW ADMINISTRATION. The report, sent to John McCain and Barack Obama with guidance for whomever is elected president in November, provides suggestions on filling key science appointments after the election.

MADISON, WI, SEPTEMBER 15, 2008–Nitrate is the most common chemical contaminant in the world's ground water, including in aquifers used for drinking-water supply. Nitrate in drinking water of the United States is regulated by the U.S. Environmental Protection Agency (USEPA) because of concerns related to infant health and possible cancer risks. Use of man-made synthetic fertilizers has steadily increased since World War II, raising the potential for increased nitrate contamination of the nation's ground water, despite efforts in recent decades to improve land-management practices.

Microscopic coprophilous or dung-loving fungi help make our planet habitable by degrading the billions of tons of feces produced by herbivores. But the fungi have a problem: survival depends upon the consumption of their spores by herbivores and few animals will graze on grass next to their own dung. Evolution has overcome this obstacle by producing an array of mechanisms of spore discharge whose elegance transforms a cow pie into a circus of microscopic catapults, trampolines, and squirt guns.

In a finding that could speed the use of sensors or barcodes at the nanoscale, North Carolina State University engineers have shown that certain types of tiny organic particles, when heated to the proper temperature, bob to the surface of a layer of a thin polymer film and then can reversibly recede below the surface when heated a second time.

September 16, 2008— Studies published in a special issue of the online journal Sexuality Research and Social Policy by the University of California Press reveal that abstinence-only-until-marriage sex education programs fail to change sexual behavior in teenagers, provide inaccurate information about condoms, and violate human rights principles.
