In mice, feeding time influences the liver's biological clock

The timing of food intake is a major factor driving the rhythmic expression of most genes in the mouse liver, researchers report April 16th in the journal Cell Reports. The findings demonstrate that body-wide signals driven ...

Cells decide when to divide based on their internal clocks

Cells replicate by dividing, but scientists still don't know exactly how they decide when to split. Deciding the right time and the right size to divide is critical for cells – if something goes wrong it can have a big ...

Mathematics meets biology to uncover unexpected biorhythms

A novel mathematical approach has uncovered that some animal cells have robust 12-hour cycles of genetic activity, in addition to circadian or 24-hour cycles. The method, published in the journal PLOS ONE, assessed the periodicity ...

A conversation between plants' daily and aging clocks

Every day you get a day older. So do plants. While the biological daily clock ticks, time passes also for the aging clock. Scientists at the Center for Plant Aging Research, within the Institute for Basic Science (IBS), have ...

Plants can tell the time using sugars

A new study by an international team of scientists, including the University of Bristol, has discovered that plants adjust their daily circadian rhythm to the cycle of day and night by measuring the amount of sugars in their ...
