Experimenting with porphyrins, which are fluorescent substances found in the body in minute amounts, he found that they went directly to cancer tissue. Since they stay on its outer limit and since they glow under ultraviolet light, they neatly outline the tumor. The porphyrins could, Dr. Figge found, carry zinc on their journey; that indicated that they might also carry isotopes.* One drawback to porphyrins as isotope carriers: they also have an affinity for the necrotic (dead) parts of a cancer, where radioactivity would do little...

Bacteria act that way only in rare genetic emergencies. Dr. Tatum selected two groups of Escherichia coli (bacteria which Jive in the intestines) and watched them. They multiplied normally by splitting in two, a solitary process. Then Dr. Tatum bombarded some of them with X rays and ultraviolet light. This damaged their insides. The metabolic cripples could still multiply by division (when coddled), but Dr. Tatum hoped that offended nature would somehow force them to repair their deficiencies...

Here's some of the equipment that fills the Medical Room: there whirlpool baths, two needle baths, one sitz bath, ten radiant heat lamps of various wattage, three infra-red lamps, one ultraviolet lamp, one microtherm, two shortwave diathermes, two long-wave diathermes, and an x-ray machine capable of producing a finished film in something like three minutes. This machine, one of the few college field house x-ray units in captivity, stands loaded during all games to determine fractures...
