Our master circadian clock resides in a small group of about 10'000 neurons in the brain, called the suprachiasmatic nucleus. However, similar clocks are ticking in nearly all cells of the body, as demonstrated by the group ...

(Phys.org) —Proteins, unlike diamonds, aren't forever. And when they wear out, they need to be degraded in the cell back into amino acids, where they will be recycled into new proteins. Researchers at Rockefeller University ...
