    Why kitchen sponges are the perfect home for bacteria

    Sponges are remarkably diverse hot spots for bacteria, in part because of the mixed-housing environment that the tools offer their tenants.

    A chain mail–like armor may shield C. difficile from some antibiotics

    Examining the structures that protect Clostridioides difficile from medicines could help researchers find new ways to target and kill the bacteria.

    Gut microbes help some squirrels stay strong during hibernation

    Microbes living in the critters’ guts take nitrogen from urea and put it into the amino acid glutamine, helping squirrels retain muscle in the winter.

    Drug-resistant bacteria evolved on hedgehogs long before the use of antibiotics

    A standoff between bacteria and antibiotic-producing fungi living on hedgehogs may have led to the rise of one type of MRSA some 200 years ago.

    A bacteria-virus arms race could lead to a new way to treat shigellosis

    As bacteria that cause shigellosis evolve to escape a virus, the microbes may become less deadly, a hopeful sign for “phage therapy.”
