Discovery opens door to efficient research model. Washington State University researchers have seen how both humans and fruit flies deploy a protein that plays a critical role in their immune responses to invading bacteria. The discovery gives scientists a model organism with which to explore ways to boost the human immune system and create infection-fighting medicines.

Naturally, there are enormous differences between humans and fruit flies, whose common ancestor goes back 800 million years...
