A designer enzyme reverses aging's chemical rust

Structural proteins that make up roughly 70 percent of the body accumulate sugar-protein damage called advanced glycation end products over decades, buildup long considered irreversible. A newly designed enzyme reversed that chemical damage in donor tissue, reopening a part of aging biology researchers had largely given up on, with the stakes being whether the effect can move from a dish to a safe therapy in a living body.
