Humans and zebrafish share mechanisms that regulate our circadian system, says TAU researcher… Circadian rhythms — the natural cycle that dictates our biological processes over a 24-hour day — does more than tell us when to sleep or wake. Disruptions in the cycle are also associated with depression, problems with we… |

Research by UCLA’s Gene Block, Christopher Colwell provides new insights into sleep difficulties among older people… A new study of the brain’s master circadian clock — known as the suprachiasmatic nucleus, or SCN — reveals that a key pattern of rhythmic neural activity begins to decline by middle age. T… |

Researchers say it could disrupt daily rhythms, affect blood sugar… Women who often work at night may face higher odds of developing type 2 diabetes, a new study suggests. The study, which focused only on women, found that the effect got stronger as the number of years spent in shift work rose, and remained even [...] |

To allow interns like me to catch a few hours rest, the hospital gave us pagers. I toted the little black plastic box into the call room, flopped down on [...] … |

Scientists identify a gene important for the daily rhythms of the sleep-wake cycle Northwestern University scientists have discovered a new mechanism in the core gears of the circadian clock. They found the loss of a certain gene, dubbed “twenty-four,” messes up the rhythm of the common fruit fly’s sleep-wak… |
