(Phys.org)—Two teams of researchers have been looking into the ways that toxins can fool cell membranes into gaining access, thereby allowing for human ailments such as cholera. One team describes a pathway that is independent ...
Researchers at Tufts University, in collaboration with a team at the University of Illinois at Champaign-Urbana, have demonstrated a resorbable electronic implant that eliminated bacterial infection in mice by delivering ...
