This illustration shows how the components of the cyanobacterial circadian clock interact in a 24-hour cycle. (Image credit: Andy LiWang) Daily cycles in virtually every aspect of our physiology are ...

Researchers have advanced our understanding of the circadian clock, the biological cycle that synchronizes with light-dark exposure. They recently developed a method to study how the circadian clock ...

CMOS clock generator creates a stable high frequency clock signal with minimal power dissipation, remains operational over an extreme temperature range, and does not require external components.

You would need a microscope to be able to see all of the miniature components etched onto the single tiny microchip powering the clock in a digital watch. But you can see them all with the naked eye ...
