We're sorry. This audio clip is no longer available. A transcript has been made available.

If you are among the many people who wake up each morning a little before your alarm clock rings, have you ever wondered why? What is it that triggers us to wake up on our own?

Researchers at the Salk Institute say they have found the gene that wakes us up. The reason that's important is that some chronic sleep disorders and diseases are linked to fragmented biological clocks.

Biologist Dr. Satchidananda Panda and his research associate Dr. Luciano DiTacchio isolated the wake-up gene. Their findings are published in this month's edition of the journal Science.
