One of the most important developments in human civilization was the practice of sustainable agriculture. But we were not the first; ants have been doing it for over 50 million years. Just as farming helped humans become a dominant species, it has also helped leaf-cutter ants become dominant herbivores and one of the most successful [...]

Breast cancer, the leading cause of death among women in France, is the most commonly occurring cancer in women. Sporadic breast cancer, which is non-hereditary, turns out to be the most widespread, representing 85 to 90% of all cases, but remains the least well-known. Researchers have just discovered the cause of 50% of sporadic breast [...]

Researchers have discovered a novel mechanism which regulates the process whereby new blood vessels are formed and wounds heal, including chronic wounds, such as those found in diabetic patients and those suffering from morbid obesity. These findings have implications for the development of new therapeutic approaches to healing damaged blood vessels and building new ones.
Dust collected from coal-tar sealcoated parking lots in Central and Eastern U.S. cities contains concentrations of polycyclic aromatic hydrocarbons (PAHs) that are about 1,000 times greater than levels found in Western cities where coal-tar sealcoat is less commonly used, according to a new study.
As the holidays arrive, a group of researchers has identified the precise mechanisms by which binge drinking contributes to clogs in arteries that lead to heart attack and stroke. The works adds to a growing body of evidence that drinking patterns matter as much, if not more, to risk for cardiovascular disease than the total [...]

A team of researchers from the Netherlands and Florida has found that plants that range beyond their normal distribution because of warming climates may have advantages over native plants. Global warming-induced biological invasions may represent an additional threat to biodiversity.

Exercise is good for more than just your waistline. A recent study suggests that regular physical activity can lower a woman’s overall risk of cancer — but only if she gets a good night’s sleep. Otherwise, lack of sleep can undermine exercise’s cancer prevention benefits.
