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 ...

Stem cells use signal orientation to guide division, study shows

Cells in the body need to be acutely aware of their surroundings. A signal from one direction may cause a cell to react in a very different way than if it had come from another direction. Unfortunately for researchers, such ...

Math model reveals insight into how first life forms were 'born'

An international team of physicists have revealed insights into how the very first life-forms made the jump from the non-living to the living world, by mathematically modelling biological states using energy waves called ...

Researchers use earthworms to create quantum dots

(Phys.org)—British researchers at King's College in London have succeeded in creating quantum dots by feeding earthworms soil laced with certain metals and then collecting the material excreted. They describe their research ...

Organic carbon from Mars, but not biological

(Phys.org) -- Molecules containing large chains of carbon and hydrogen--the building blocks of all life on Earth--have been the targets of missions to Mars from Viking to the present day. While these molecules have previously ...

Study dusts sugar coating off little-known regulation in cells

In Alzheimer's disease, brain neurons become clogged with tangled proteins. Scientists suspect these tangles arise partly due to malfunctions in a little-known regulatory system within cells. Now, researchers have dramatically ...
