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.

In the research, which included more than 38,000 people from 10 countries, the odds of being obese as an adult were 22 percent higher for those born by C-section, compared with those born by vaginal delivery. The new study is the largest to find a link between Caesarean delivery and weight in adulthood. "There are good reasons why C-section may be the best option for many mothers and their babies, and C-sections can on occasion be life-saving," study researcher Dr. Neena Modi, of Imperial College London, said in a statement.

The additions include four planets about 2-1/2 times as big as Earth that are the right distance from their parent stars for liquid surface water, which is believed to be key for life. The discoveries were made with the National Aeronautics and Space Administration's planet-hunting Kepler space telescope before it was sidelined by a pointing system problem last year. The tally of planets announced at a NASA press conference on Wednesday boosted Kepler's confirmed planet count from 246 to 961.

For example, mothers who stay home with young children today spend about 14 hours less per week doing physical activity than they did in 1965, the study found. A team of researchers at several universities conducted the new analyses, led by Dr. Edward Archer, exercise scientist and epidemiologist at the University of South Carolina and a research fellow at the University of Alabama. To avoid this problem of (frequently inaccurate) self-reporting, Archer's team applied a new set of equations to health data collected between 2005 and 2006, based on more-accurate measures of energy expenditure using activity monitors and urine analysis, the "gold standards" of physical activity studies.

Children from multiple births(i.e., twins and triplets) were 33 percent more likely to be diagnosed with anorexia later in life compared to children from single births, the study found. The results surprised the researchers, said study researcher Anna Goodman, of the Centre for Health Equity Studies at Stockholm University. Usually, any health differences between children from multiple births and those from single births can be attributed to prematurity (because twins and triplets are often born at least slightly preterm), Goodman said.

However, those within this group who were exposed to second-hand smoke for more than 10 years during childhood, or as an adult at home or at work, were 17 percent more likely to miscarry, 55 percent more likely to give birth to a stillborn child, and 61 percent more likely to have ectopic pregnancies, in which the embryo is implanted outside the uterus and cannot survive, compared with women who were never exposed to second-hand smoke. The findings "suggest that lifetime second-hand smoke exposure contributes to a great number of adverse pregnancy outcomes each year," the researchers wrote in their study published today (Feb. 26) in the journal Tobacco Control. The effects of cigarette smoking by pregnant women has been studied extensively in the past several decades, and is known to be associated with increased risk of infertility, preterm birth, miscarriage and stillbirth and other pregnancy complications, the researchers said.

Today (Feb. 27) the agency announced proposed changes to the labels, to reflect the latest nutrition science and the growing understanding of the link between our diet and chronic diseases such as obesity and heart disease, the FDA said. One of the biggest changes the FDA is proposing is to update the serving sizes on the labels, so they better reflect what people actually eat, the FDA said. For example, a single serving of ice cream is currently listed as half a cup, but the new labels would list the serving size as a full cup, the FDA said.
