Study reveals how certain genetic mutations can shorten the timing of the circadian clock, making some people extreme "morning larks" because their internal clock operates on a 20-hour cycle, as opposed to a 24-hour cycle. Read More
Stress makes the circadian clock tick faster and better. Read More
POMC, a gene which regulates the stress response system, and PER2, a gene associated with circadian regulation, are altered in women who drank moderate-to-high amounts of alcohol during pregnancy and their newborns. Read More
A new study reports middle aged people who are early risers have a lower risk of developing depression. Read More
Researchers have found an association between the Per2 gene and breast cancer. The Per2 gene plays an important role in both the body's circadian clock and mammary gland development. Read More
Researchers present a new approach to creating genetic knock out mice to help investigate circadian rhythm. Read More
A new study reports on a link between circadian cell disruption and cancerous tumor growth. Read More
Researchers have identified a molecular switch which helps regulate the circadian clock and allows the body to keep time. Read More
Mutations in a pair of genes, which normally help regulate eating scheduled and keep them in sync with daily sleep rhythms, may play a role in so called night eating syndrome. Read More
