Functional genomics gets tiny
A little more than a decade ago, researchers discovered an ancient mechanism that cells use to silence genes. Like a dimmer switch turning down a light, RNA interference (RNAi) dials down gene activity in ...

Japanese honeybees swarm huge hornet predator to kill it with heat
Japanese honeybees face a formidable foe in the Asian giant hornet, a fierce predator that can reach 40mm long or larger, but the bees have developed a novel defense mechanism: they create a "hot defensive bee ball," swarming ...
