Researchers have constructed a new synthetic bacterium that detects Pseudomonas aeruginosa, a common microbe and a leading cause of hospital-acquired infections, and explodes, releasing antimicrobials that kill the invaders. 

The results, published today (August 16) in Molecular Systems Biology, suggest that the engineered bacteria might eventually be used to prevent or treat infection with P. aeruginosa in humans.

Some participants in the Amgen Scholars Program (that I write for) posted this awesome musical story about their summer science research at Caltech. To the tune of Michael Bublé's "Haven't Met You Yet," it's "Just Haven't Made You Yet":
