Short summary

Medical Xpress reports a study describing how sulfenylation and persulfidation regulate brain proteins during aging, and a new analysis pointing to low overdiagnosis in breast cancer screening. Medical Xpress also reports a modeling study in The Lancet on U.S. Medicare's Most-Favored-Nation pricing, while STAT reports an analysis suggesting secretive pharma deals may undermine that policy. Medical Xpress additionally reports a third U.S. measles death in 2026, a study on pancreatic tumors using a clotting pathway to build immune shields, and a perspective on protein restriction and healthy agi
