Salmonella and many other bacterial pathogens use a nano syringe-like device to deliver toxic proteins into target human cells. Now scientists at Yale and University of Texas Medical School-Houston have used cryo-electron tomography to reveal the molecular structure of this device, which is about 1/1000th the width of a human hair.
