[shiura]’s Hollow Clock 3 is a fantastic 3D printed take on a clock movement that uses a hidden mechanism to pull off its unusual operation. The Hollow Clock has no face, just an open space with an ...

Analog clocks are beautiful things inside, using ornate gear trains to keep track of time in a dance of mechanical beauty. However, all too often, the complexity is hidden inside. This gear clock ...

A set of core clock proteins organize themselves into a handful of molecular machines that control the precise workings of the body's circadian rhythms, new research has found. Scientists have long ...

Researchers find that a key circadian clock controlling kinase, CK1D -- controlling the stability of PER2 -- has two forms, one that stabilizes PER2 and one that destabilizes it. A long-studied factor ...

man coming off his night shift gets into his car. He knows it's the most dangerous part of his day, a time when his body aches for sleep. He struggles to stay awake while driving home. He's tried ...

A recent report looks at a 'clock in a test tube' composed of the cyanobacterial proteins KaiA, KaiB and KaiC, revealing that these dancing proteins swap partners to keep track of time. The clarity, ...

Scientists have long known that circadian clocks--biochemical oscillators that control physiology, metabolism and behavior on a roughly 24-hour cycle--are present in all forms of life, including ...
