Sex-like DNA exchange in starving bacteria occurs over 100 times more often than spontaneous mutations

How do bacteria adapt when resources run low? ISTA researchers have found that, under starvation stress, E. coli can use bacteriophages and CRISPR-Cas immunity to transfer and incorporate DNA, accelerating genetic reshuffling. ...

Catalog of mitochondria across life's family tree unearths unusual functions

A research consortium has generated the broadest look yet at the proteins that make up mitochondria, capturing the organelle's diversity across multiple branches on the tree of complex life. With major contributions from ...

Eye-eating amoeba resists treatment—understanding its biochemistry could help

In water, soil and air all around us lives a free-living, single-celled organism called Acanthamoeba. Most of the time, Acanthamoeba keeps to itself. On rare occasions, though, the amoeba infects humans and can cause severe ...

Key protein for cells' gene regulation needs a chaperone to do its job

A protein that's essential to every cell's ability to turn off unnecessary genes is well known for its key function of compacting genes and its connection to cancer when it undergoes mutation. But until now, scientists weren't ...
