Smithsonian scientists show differing patterns of rainforest biodiversity
... the sedentary lifestyles of many species. Some spend their entire lives on a single plant, but theyve got wings. They may not want to fly, but they can if they need to, said Smithsonian scientist Scott Miller, an author of the Nature paper.

In addition, obesity is increasing dramatically in all populations and is a major cardiovascular risk factor in women after menopause.

Aggressive orange males spend a lot of time in the open and need stripes to help them escape from predators (the optical effect of stripes on fast-moving prey makes them hard to catch).
