Pinpointing the molecular mechanisms of ageing

Although each and every one of us goes through it, ageing is a poorly understood process. Researchers have used a biomarker called the epigenetic clock to identify a gene that is closely linked to ageing in humans. The study, ...

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 ...

Proactive personality has stronger wake-sleep rhythm

Proactive zebrafish appear to have a much stronger wake-sleep rhythm than reactive fish. In the most reactive fish, rhythmicity appears to be lacking completely. This is shown with research by Leiden biologists, published ...

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 ...

New insights into the inner clock of the fruit fly

Several months ago, professors Jeffrey Hall, Michael Rosbash and Michael Young received the Nobel Prize for their work on deciphering the mechanisms of the biological clock. Many other scientists around the world are also ...

Determining the timing of methanogen evolution

Early forms of life very likely had metabolisms that transformed the primordial Earth, such as initiating the carbon cycle and producing most of the planet's oxygen through photosynthesis. About 3.5 billion years ago, the ...
