(Phys.org) —An international team of researchers working in Germany has found that blackbirds that live in the city tend to have different circadian rhythm cycles than do blackbirds that live in a nearby forest. In their ...
(Phys.org)—It's not just a few key genes and proteins that cycle on and off in humans in a 24-hour circadian pattern as the sun rises and falls. Thousands of genes in organs throughout the body show predictable daily fluctuations, ...
