Delivering a one-two punch to superbugs to fight infections
Rakesh Krishnan sits at a computer staring at a 3D rendering of a protein.

Researchers led by César de la Fuente of the Perelman School of Medicine have created new peptides that fight hard-to-treat “superbug” infections by punching holes in bacterial cells and stimulating immune cells to signal for more defenders.
