For four decades, a critical molecular switch governing cell life and death remained structurally invisible, leaving researchers designing cancer and neurological therapies largely in the dark. Scientists at Mayo Clinic have now mapped the complete three-dimensional architecture of protein kinase C beta in human tissue, revealing not only how the enzyme activates but how an existing breast cancer drug silences it through an indirect, previously unrecognized mechanism. This moment belongs to a long tradition in medicine where seeing clearly — truly seeing — transforms what becomes possible, ope
