Pygmy phenotype developed many times, adaptive to rainforest

The small body size associated with the pygmy phenotype is probably a selective adaptation for rainforest hunter-gatherers, according to an international team of researchers, but all African pygmy phenotypes do not have the same genetic underpinning, suggesting a more recent adaptation than previously thought.

Aspirin, take two: Research identifies a second effect of the drug against inflammation

Aspirin has a second effect, researchers have found: Not only does it kill cyclooxygenase, thus preventing production of the prostaglandins that cause inflammation and pain, it also prompts the enzyme to generate another compound that hastens the end of inflammation, returning the affected cells to homeostatic health.
