You’ve doubtless seen those ubiquitous clock modules, especially when setting clocks for daylight savings time. You know the ones: a single AA battery, a wheel to set the time, and two or three hands ...

The activation and inactivation mechanisms of a key protein involved in the circadian clock system of cyanobacteria -- an important organism in the evolution of such internal clocks -- have long ...

The circadian clock in cyanobacteria represents one of the most elegant and thoroughly studied biological timekeeping systems. This oscillator is principally driven by the concerted actions of Kai ...

Some time ago [Kelton] was working on a clock inspired by Rube Goldberg contraptions. It uses only a single motor, and he’s proud to now show off the finished product (video, embedded below.) The ...

In April of this year, Spanish athlete Beatriz Flamini emerged into the light after a 500-day stay in a cave. Her descent underground is probably the longest undertaken by a long stretch. Flamini says ...

Researchers have identified a key mechanism involved with the setting of the circadian clock of cyanobacteria—a model organism for study by chronobiologists due to the organism having one of the ...
