Most successful businesses would not accept spending $218 million on lost time, but that's the amount NHL owners pay out every year to players who miss games due to injury, according to new research. More than 63 per cent of the 1,307 NHL players that laced up skates during the 2009-10, 2010-11 and...

Researchers have discovered the genetic machinery that turns a common gut bacterium into the Swiss Army knife of the digestive tract -- helping us metabolize a main component of dietary fiber from the cell walls of fruits and vegetables.

A new approach to harvesting solar energy could improve efficiency by using sunlight to heat a high-temperature material whose infrared radiation would then be collected by a conventional photovoltaic cell. This technique could also make it easier to store the energy for later use, the researchers...

"Cancer resembles a state of chronic wound healing, in which the wound-healing program is erroneously activated and perpetuated," says Professor Adrian Krainer of Cold Spring Harbor Laboratory. In a paper published today in Nature Structural & Molecular Biology, a team led by Dr. Krainer reports...

During the abrupt cooling at the onset of the so-called Younger Dryas period 12680 years ago changes in the water cycle were the main drivers of widespread environmental change in western Europe.Thus, the regional impacts of future climate changes can be largely driven by hydrological changes, not...
