To assess the role of the chemical, famous for its rotten-egg stench, Rui Wang of Lakehead University, in Thunder Bay, Ontario, and colleagues created mutant mice that were unable to produce cystathionine γ-lyase (CSE), an enzyme suspected of forming H2S in the body. The mice produced significantly less H2S in their cardiovascular tissue and had . . .
