Atomic fountain clocks are becoming still more stable
— 19 Mar 2009 12:20 | PhysicsCaesium fountains are more accurate than 'normal' atomic caesium clocks, because in fountains the caesium atoms are cooled down with the aid of laser beams and come ever slower - from…
How your body clock avoids hitting the snooze button

Genetic clock makers at UC San Diego publish their 'timepiece' in Nature
— 30 Oct 2008 12:16 | BiologyUC San Diego bioengineers have created the first stable, fast and programmable genetic clock that reliably keeps time by the blinking of fluorescent proteins inside E. coli cells. The…
Study shows more genes are controlled by biological clocks
— 6 Sep 2008 19:54 | BiologyThe tick-tock of your biological clock may have just gotten a little louder. Researchers at the University of Georgia report that the number of genes under control of in living things…
Scientists identify food-related clock in the brain
