Scientists learn how to ramp up microbes’ ability to make memories

Scientists learn how to ramp up microbes’ ability to make memoriesResearchers have identified a mutation that prompts bacterial cells to acquire genetic memories 100 times more frequently than they do naturally. This discovery provides a powerful research tool and could bring scientists one step closer to developing DNA-based data storage devices. More »

‘Programmable’ antibiotic harnesses an enzyme to attack drug-resistant microbes

“Programmable” antibiotic harnesses an enzyme to attack drug-resistant microbesBy co-opting a system bacteria normally use to defend themselves, researchers targeted and killed off colonies of the antibiotic resistant Staph cells on mouse skin. The treatment left behind the drug-susceptible microbes. More »
