This was our first surprise," study author Yukari Takeuchi, of the University of Tokyo, said in a statement. Researchers knew for a long time that in sheep and goats, the males somehow stimulated the release of reproductive hormones in females, but now the new study has identified the actual compound at work, said John J. McGlone, a Texas Tech University professor, who was not involved in the study. "When there is a pheromone in one species, what we are learning is that it often has effects on other species."

Since an exceptionally warm 1998, there has been "a short-term slowdown in the warming of Earth's surface," Britain's Royal Society and the U.S. National Academy of Sciences said in a report. But, they said, that "does not invalidate our understanding of long-term changes in global temperature arising from human-induced changes in greenhouse gases." The warming slowdown has emboldened those who question the evidence about climate change and ask whether a shift in investments towards renewable energies such as wind and solar power, advocated by many experts, is really needed. A build-up of greenhouse gases from human activities, mainly the burning of fossil fuels, is warming the atmosphere and the oceans, raising sea levels and melting Arctic ice, the report said, supporting the long-held view of a U.N. panel of climate scientists.

Today (Feb. 27), the Food and Drug Administration announced plans to update nutrition labels to better reflect the latest nutrition science, and the growing understanding of the link between diet and chronic diseases, the agency said. The proposal comes as a growing number of Americans say they read nutrition labels. About 54 percent of U.S. consumers said they read these labels "often" in 2008, up from 44 percent in 2002, according to FDA statistics.

Harvard Researcher Says You May Doing It Wrong A recent study co-authored by Harvard University doctoral student Silvia Bellezza, suggested that people who go out on a limb with their clothing selections at work or in job interviews have the potential to appear more successful. Business News Daily recently reported on Bellezza's findings. Resistance to conformity pressures can take distinct forms across individuals. Of particular relevance to our work is Tian, Bearden and Hunter's (2001) conceptualization, which suggests that people exhibit three main behavioral manifestations of nonconformity.

In a recent Swiss study, researchers discovered that more bacteria cover a stethoscope's diaphragm (the part that's held against a patient's body) than all regions of a physician's hands, except the fingertips. There are no official guidelines that tell doctors how often they should clean their stethoscopes, the researchers said. "The more you have bacteria on the fingertips, the more you find bacteria on the membrane of the stethoscope," said study author Dr. Didier Pittet, director of infection control at the University of Geneva Hospitals.

Researchers found that blocking a type of genetic material called micro-RNA lowered the inflammation in mice that were grafted with skin from people with psoriasis. Psoriasis is an autoimmune disease (in which the immune system attacks the body's own tissues), and is one of the most common skin conditions worldwide, affecting about 3 percent of the human population. According to the National Psoriasis Foundation, the condition affects about 7.5 million Americans, including celebrities such as Kim Kardashian and country singer LeAnn Rimes.
