A gene called Npas4, already known to play a key role in balancing excitatory and inhibitory inputs in brain cells, appears to also be a master timekeeper for the brain's circadian clock, new research led by UT Southwestern ...

Certain body parts, such as the skin or liver, can repair themselves after damage. Cell regeneration is the phenomenon by which cells that are still functional proliferate to compensate for cellular damage. For the past 30 ...

The circadian clock system (from the Latin "circa diem," about a day) allows organisms to anticipate periodic changes of geophysical time and to adjust to those changes. Nearly all cells comprise molecular clocks that regulate ...

More than 20 years ago, the lab of developmental biologist Olivier Pourquié discovered a sort of cellular clock in chicken embryos where each "tick" stimulates the formation of a structure called a somite that ultimately ...

Scientists have recently recognized that cells of the same type can behave differently in response to stimulation. In a new study, Yale researchers have shown how these varied responses are due in part to a desynchronized ...

Increasing sunlight intensity extends the sleep duration and results in a longer midday siesta which delays the resumption of activity to the evening. What sounds like an analysis of the effects of the unusually hot summer ...

Astrocytes, 'caretaker' cells that surround and support neurons in the brain, play a much more important role in circadian rhythms, the body's 24-hour internal clock, than previously understood.
