After contracting dengue fever once, certain people who encounter the virus again develop much more severe infections. New research identifies an immunological signature that could help identify and better treat these patients. More »
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 »
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.
