Scientists learn how insects 'remodel' their bodies between life stages
It's one of life's special moments: a child finds a fat caterpillar, puts it in a jar with a twig and a few leaves, and awakens one day to find the caterpillar has disappeared and an elegant but apparently ...

Fruit-fly study adds weight to theories about another type of adult stem cell
It turns out that an old dog - or at least an old fruit-fly cell - can learn new tricks. Researchers at the Stanford University School of Medicine have found that mature, specialized cells naturally regress to serve as a ...
