Siberian hamsters show what helps make seasonal clocks tick

Many animals, including humans, have internal clocks and calendars to help them regulate behavior, physiological functions and biological processes. Although scientists have extensively studied the timekeeping mechanisms ...

Plants do sums to get through the night, researchers show

(Phys.org) —New research shows that to prevent starvation at night, plants perform accurate arithmetic division. The calculation allows them to use up their starch reserves at a constant rate so that they run out almost ...

Researchers devise a new way to plot circadian clock

(Phys.org)—Everyone has an internal clock, that mysterious process which controls sleeping and hunger patterns, but now researchers are finding out that because the internal clock also controls metabolism, it would be helpful ...

To Arctic animals, time of day really doesn't matter

In the far northern reaches of the Arctic, day versus night often doesn't mean a whole lot. During parts of the year, the sun does not set; at other times, it's just the opposite. A new study reported online on March 11th ...

Bacteria can tell the time

Humans have them, so do other animals and plants. Now research reveals that bacteria too have internal clocks that align with the 24-hour cycle of life on Earth.

Understanding the circadian clocks of individual cells

Two new studies led by UT Southwestern scientists outline how individual cells maintain their internal clocks, driven both through heritable and random means. These findings, published online May 1 in PNAS and May 27 in eLife, ...
