...photographic film. Blake started out by simply trying to untangle a peculiar phenomenon that he had been observing for a few months: faint positive images that unaccountably appeared on sheets of film. He was sure that the reaction was caused by any one of countless chemicals in his photo lab-but which one? Working day and night under the red darkroom lights, he dabbled with hundreds of dyes and compounds. Finally, on Dec. 7, 1961, he reached up among the rows of bottles and picked a rarely used mixture called mercaptan l-phenyl-5-mercaptotetrazole. When he swabbed the mixture...
Blake's chief immediately got on the phone to Wilmington and won approval for a new, expanded lab budget. Five researchers explored more than 6,000 detailed technical references before concluding that "Blake's Effect" really meant a fresh and important development: a film that directly produces a positive image, doing away with the traditional steps of making a negative and printing a positive. When the specially coated film is exposed to light, certain parts of its emulsion are broken down in a process so mysterious that scientists themselves are a bit baffled. The film can then...
...Rubin, once a postdoctoral fellow in Dr. Dulbecco's lab, worked with viruses that cause leukemia in fowl and have a nucleus consisting of ribonucleic acid (RNA). The work of these men, said the awards committee, "promises to contribute decisively to our eventual understanding of the nature of cancer...
...appears listless, fails to gain weight, and suffers from jaundice, vomiting and diarrhea, his mother can hardly be expected to know that he may lack the enzyme galactose1 -phosphate uridyl transferase. Neither can doctors, unless they send samples of the baby's blood and urine for timeconsuming, costly lab tests. Then, if the tests show an excess of galactose (milk sugar) in the blood or urine, doctors know what the trouble is and how to remedy...
...Hodgkin's orderly mind seems to thrive on a diet of clutter and clatter. After graduation from Oxford, when she went into research, her first lab was in a dingy basement under the university museum. It was her precarious exercise to climb a ladder to a gallery while carrying the delicate crystals with which she worked. But whatever the circumstances, she maintained an elegance of appearance and achievement. No distraction was enough to spoil the work that led to a thorough knowledge of the penicillin molecule, and to the discovery of the structure of Vitamin B12, the recalcitrant molecule...
