Infected caterpillars become zombies that climb to their deaths
By tampering with genes involved in vision, a virus can send caterpillars on a doomed quest for sunlight.

Ponds made to control floods can spew climate-warming gases, study finds
Younger stormwater ponds can release more carbon in gases than they absorb, a study finds. That could aggravate global warming.
