Scientists are much closer to understanding the causes of a host of maladies, from jet lag and shift-work problems to sleep disorders related to aging, thanks to striking new research on the brain's "biological clock" -- the tiny but hugely mysterious aggregation of cells that dictates the body's daily rhythms.

In today's issue of the journal Cell, Joseph S. Takahashi and colleagues from Northwestern University describe "definitive proof" that a heretofore unknown substance has a key role in controlling the biological clock in mice and identify the gene that determines the chemical's ...
