CCSM3 shows global temperatures could rise by 2.6 degrees Celsius (4.7 degrees Fahrenheit) in a hypothetical scenario in which atmospheric levels of carbon dioxide are suddenly doubled. That is significantly more than the 2 degree Celsius (3.6 degree Fahrenheit...European Commission approves Herceptin + Taxotere as 1st-line therapy in HER2-positive breast cancer

...sue of DNA and Cell Biology. "We believe fibulin-5 shows real promise as a cancer therapy," said Schiemann. "When we slightly altered the naturally occurring protein it was even more effective at inhibiting the sprouting of new blood vessels." Cancer tumors need nutrients and oxygen supplied by blood vesse...Antioxidants during pregnancy may help prevent birth defects tied to alcohol
... "What makes this study unique is that it shows for the first time that giving antioxidants to a pregnant mother at the same time she's exposed to alcohol can diminish the incidence of major malformations," said Dr. Kathleen K. Sulik, professor of cell and developmental biology at UNC's School of ...Scientists learn how adjuvant makes vaccines effective

"Our research shows that alum injection triggers the accumulation of Gr1 cells in the spleen, which prime B cells and facilitate their response to vaccines," said senior author John Cambier, Ph.D., Chairman of the Integrated Department of Immunology at National Jewish a...Improved nutrition could prevent more than half of the world's child deaths annually
...School's Center for Human Nutrition. "Our analysis shows that even children who were small, but whose weight would not classify them as malnourished, were twice as likely to die as children in our reference group," she said. This analysis confirms earlier research that showed that 55 percent of all child ...Espionage may have driven the evolution of bee language according to UCSD-led study in Brazil
..., is strong support for that hypothesis because it shows that bees can indeed use the chemical markings deposited by bees of other species to home in on and take over their food source. The paper will appear in print in Proceedings of the Royal Society in August. "We show that foragers of an aggressive sp...Other highlights in the June 16 JNCI

Several studies have suggested that circulating levels of sex hormones, particularly estrogen, are associated with breast cancer risk, but i...Study helps explain island populations' susceptibility to exotic diseases

The study shows that people on islands have different immune systems "and this may be the explanation for their susceptibility to invasive diseases," Foufopoulos said.
