New sleep genes found: Researchers discover that protein called Taranis could hold key to good night's sleep

Most of us need seven to eight hours of sleep a night to function well, but some people seem to need a lot less sleep. The difference is largely due to genetic variability. In research published online June 18th in Current Biology, researchers report that two genes, originally known for their regulation of cell division, are required for normal slumber in fly models of sleep: taranis and Cyclin-dependent kinase 1 (Cdk1).
