A search through decades-old frozen infant stool samples has yielded rich dividends for scientists. They have customized a laboratory technique to screen thousands of samples for norovirus, a major cause of acute gastroenteritis outbreaks in people of all ages. What they discovered about the rate of evolution of a specific group of noroviruses could help [...]
Cows might be able to gain more weight while consuming less, potentially saving farmers up to 40 percent of feed costs.

The consumption of fish has no major role in the prevention of heart failure, according to results from a large prospective population study. The study, which was started in 1990 and involved all men and women over the age of 55 living in a suburb of Rotterdam, found no difference in the risk of developing [...]

Challenge a simple pocket calculator at arithmetic and you may be left in the dust. But even the most sophisticated computer cannot match the reasoning of a youngster who looks outside, sees a fresh snowfall, and knows how to bundle up for the frosty outdoors. For artificial intelligence scientists, enabling computers to have such human-level [...]

Engineers have boosted stem cells’ ability to regenerate vascular tissue (such as blood vessels) by equipping them with genes that produce extra growth factors (naturally occurring compounds that stimulate tissue growth). In a study in mice, the researchers found that the stem cells successfully generated blood vessels near the site of an injury, allowing damaged [...]
