The physicist who found cancer's cure

Rosenberg noticed bacteria near platinum electrodes stopped dividing and stretched into grotesque filaments, but the culprit wasn't the electric field—it was platinum compounds leaching from the electrodes into the growth medium. That accidental discovery of cisplatin's DNA-crosslinking mechanism became the backbone of first-line cancer treatment for lung, testicular, ovarian, cervical, and bladder cancers, now synthesized primarily in Gujarat from South African platinum.
