Scientists have prototyped a new method for "rationally engineering" enzymes to deliver improved performance. They have devised an algorithm, which takes into account an enzyme's evolutionary history, to flag where mutations ...

G protein-coupled receptors (GPCRs) are the largest and most diverse group of cell surface proteins in humans. These receptors, which can be seen as "traffic directors," transmit signals from the outside to the inside of ...

Researchers at the Chinese Academy of Agricultural Sciences, China, have applied machine learning to genetic sequence data from wild and domestic European grapes.
Although the regulation of sleep—how much, when, and how sleep occurs—is mainly considered to be controlled by the brain, sleep deprivation also affects the body, and signals from the body can affect sleep. However, the ...

A pair of researchers at Michigan State University has conducted an experiment with Escherichia coli bacteria meant to help settle a long-time debate in the evolutionary community. They have written a paper describing their ...
Scientists have identified a new role for a protein complex at the center of a human genetic disorder called Bardet-Biedl syndrome, or BBS, for which there is currently no cure.

Like disease in humans, parasites can wage a deadly evolutionary "arms race" against their hosts, even driving small populations to extinction if they mutate more quickly and gain the upper hand.
