While the world's best skiers and snowboarders at the Vancouver 2010 Olympic Winter Games compete with helmets on, many other skiers and snowboarders are choosing to forgo this important piece of safety equipment. In fact, many skiers and snowboarders place fashion before safety, according to doctors.

Researchers have created a genome-scale map of 26 different cancers, revealing more than 100 genomic sites where DNA from tumors is either missing or abnormally duplicated compared to normal tissues. The study, the largest of its kind, finds that most of these genetic abnormalities are not unique to one form of cancer, but are shared across multiple cancers.

Scientists in France have transformed the chemical energy generated by photosynthesis into electrical energy by developing a novel biofuel cell. The advance offers a new strategy to convert solar energy into electrical energy in an environmentally-friendly and renewable manner. In addition, the biofuel cell could have important medical applications.

Building on Nobel Prize-winning work creating fluorescent proteins that light up the inner workings of cells, a team of researchers has developed biological probes that can stick to and light up tumors in mice. The scientists were able to spot and remove more cancerous tissue in mice injected with the fluorescent probes than in those mice without the fluorescent probes, upping survival five-fold.

Scientists have found that adding a humanized monoclonal antibody called daclizumab to standard treatment reduces the number of new or enlarged brain lesions in patients with relapsing multiple sclerosis.

The gargantuan plankton-eating whales of today--such as the humpback whale and the blue whale–have long been thought to be the evolutionary masters of their filter-feeding technique. New research, published online February 18 in two papers in Science , however, shows that millions of years before these massive mammals evolved, huge fish fruitfully employed the same approach--and that it wasn't necessarily these cetaceans' skill, but rather changing climate and new food source diversity, that allowed them to eventually dominate their domain.

People who are usually happy, enthusiastic and content are less likely to develop heart disease than those who tend not to be happy, according to a major new study.

The surface area and conductivity of a lattice-like Nanonet coated with silicon particles proves to be a high-performing anode material for Lithium-ion batteries, researchers report.
