The simple tricks to fool Earth-evolved humans into living on Mars time. One Hour Short of Mars Time A new study says exposure to blue light at the right times, along with smarter caffeine use, can help humans adjust our biological clocks to the 24.6 hour Mars day rather than Earth's day.

The settings for a person’s biological clock might provide clues to when, during the day, he or she will be more active. What’s more, these same settings could be linked to what time of day a person might die, a new study finds.

New research supports a largely unrecognized culprit in circadian rhythm disturbances: the gradual yellowing of the lens and the narrowing of the pupil that come with age.

New research at Oregon State University provides evidence for the first time that disruption of circadian rhythms – the biological 'clocks' found in many animals – can clearly cause accelerated neurodegeneration, loss of motor function and...

A group of biology researchers, led by Akhilesh Reddy from Cambridge University have found an enzyme that they believe serves as a circadian clock that operates in virtually all forms of life. In a paper published in the journal Nature, they describe a class of enzymes known as peroxiredoxins which are present in almost all plants and other organisms and which appear to serve as a basic ingredient in non-feedback loop biological clocks.

In the pioneering days of chronobiology, it was a common practice to go out in the woods and collect as many species as possible and document the existence of circadian rhythms. Technical limitations certainly influenced what kinds of organisms were usually tested.

Researchers explain the molecular linkage between the circadian clock and the deadly heart rhythms that lead to sudden death, which is more likely to occur shortly after waking in the morning and in the late night.

Biologists at Rice University have discovered that while plants might look fairly inactive in the day, they are surreptitiously preparing for battle with hungry insects.

Scientists know that plants can actually 'sense' day length, and 'schedule' their growth to coincide with specific environmental conditions.
