Scientists engineer DNA 'receipt book' to store cells' history

If you want to track a person's activities for a day, you could call them up every ten minutes and ask what they're doing. Easier, though, would be to provide them with a journal to log their own actions. Scientists often ...

Early land plants evolved from freshwater algae, fossils reveal

The world may need to start thinking differently about plants, according to a new report in the journal Science by researchers who took a fresh look at spore-like microfossils with characteristics that challenge our conventional ...

New mathematical model reveals how major groups arise in evolution

Researchers at Uppsala University and the University of Leeds presents a new mathematical model of patterns of diversity in the fossil record, which offers a solution to Darwin's "abominable mystery" and strengthens our understanding ...

Compound controls biological clock with light

Researchers at Japan's Institute of Transformative Bio-Molecules (ITbM) of Nagoya University, the Netherlands' University of Groningen, and colleagues have found a new way to regulate the biological clocks of cells. Further ...

What drives circadian rhythms in the polar regions?

In temperate latitudes, the right timing is crucial for almost all living things: Plants sprout with the advent of spring, bees know the best times to visit flowers, people get tired in the evening and wake up again in the ...

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 ...
