On the surface, it's simple: when night falls, our bodies get sleepy. But behind the scenes, a series of complex molecular events, controlled by our genes, is hard at work to make us groggy. Now, research suggests that a newly identified gene known as insomniac may play a role in keeping us asleep. By cloning and testing this gene in fruit flies researchers say they have discovered an entirely new mechanism by which sleep is regulated.
