Researchers 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 »
Sifting soil from city parks, scientists have found microbial genes capable of making compounds whose potent effects can make them valuable tools in the fight against disease. Their research suggests that many more await discovery, even in a place as mundane as urban dirt. More »
The bacteria we carry within us could be a untapped source of new drugs. Researchers put this idea to the test by mining the human microbiome for new antibiotics—and identified two compounds that might be effective against some particularly dangerous bacteria. More »
Working in animal models, scientists have found that an enzyme produced by one microbe can shield the gut against attack from other, more harmful bacteria. The findings could potentially inform the design of new probiotics for use against dangerous pathogens like those spreading hospital-acquired infections. More »
Like humans, bacteria come under attack from viruses—and their immune systems, like ours, are capable of remembering a virus so as to preempt any future invasion. New research explores how the bacterial immune system CRISPR stores and ranks these memories. More »
In devising a method to readily grow hepatitis C in the laboratory, scientists might have overcome a major hurdle for basic research into the virus and the disease it causes.
The enzyme Cas9 is well known for its ability to make precise cuts in a genome. New research reveals a new role for Cas9 in its native bacteria: helping the microbial immune system acquire a memory of an invading virus. More »
