Calorie restriction leads to some brain benefits but not others in mice
...that calorie restriction, like antioxidants, helps protect
the brain against free radical damage. To test their theory, the team compared young and old mice fed normal diets with old mice fed 35 percent fewer calories starting at about one year old. One year for mice is roughly the physiological equivalent ...

One-way processes speed degradation of coral reefs
Efforts to protect
coral reefs should be refocused on terminating self-reinforcing processes that accelerate degradation of these biological marvels, according to a Forum article published in the November 2004 issue of BioScience. The article, by Charles Birkeland of t...
