Discoveries of microbial communities that transfer electrons between cells and across relatively long distances are launching a new field of microbiology.
Research traces the evolution of a gene variant that reduces the risk of Alzheimer’s disease, finding that it originally evolved in response to infectious bacteria.
In work that has not yet been peer-reviewed, researchers present evidence that microbes can and do live inside the venom glands of several dangerous species. It remains unclear whether they’re to blame for infections linked to bites.
