Credit: CDC Like any good military unit, infectious bacteria have access to numerous weapons and efficient communication systems. But like soldiers in the field, they're also susceptible to suicide bombers. Researchers have used the tools of synthetic biology to create an Escherichia coli cell that can infiltrate foreign bacteria and explode, killing off the pathogens along with itself. The project, says bioengineer Chueh Loo Poh of Nanyang Technological University in Singapore, was "inspired by nature," particularly by quorum sensing,...
