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.

The process resembles a primitive form of sexual reproduction and may help bacterial populations adapt to changing conditions. The findings were published in Molecular Biology and Evolution.

Google figures out how to watermark AI-designed proteins

AI-based tools seem to be causing security threats on a nearly daily basis, in part because we've been slow to recognize potential threats. One area where we seem to be ahead of the game, however, is in biosecurity. As with most things biological, utility goes hand in hand with t
