Widely touted preparations such as triparanol and nicotinic acid (one of the B vitamins, also called niacin) do lower blood cholesterol, but they have undesirable side effects. Triparanol interferes with the liver's formation of cholesterol, forces it instead to produce a suspicious substance called desmosterol that is chemically related to cholesterol-and may even have the same damaging effect on arteries. Nicotinic acid, to be effective, must be administered in massive doses. The result: flushing, itching, nausea, headaches, changes in the blood...
Rodger W. Griffin, director of Chem 20 labs, blamed the accidents on "negligence on the student level" during the experiment, the preparation of sulfanilamide from benzene. The lab manual contains a special note warning students that chlorosulfonic acid is strongly corrosive and reacts violently when in contact with water...
Chumbley explained that water vapor present in supposedly dry crystals of acetanilide reacted violently with chlorosulfonic acid and the mixture "exploded in my face." His burns were "nothing serious and will be completely healed in two weeks," he said...
Four young scientists were among the new professors promoted from within the faculty: James D. Watson, 32, a biologist well known for the Watson-Crick model of the structure of Desoxyribonucleic acid (DNA), a long-chain molecule which determines hereditary traits in living cells; Richard Wilson, 34-years-old expert in high energy physics; Arthur E. Bryson, Jr., 35, whose field is missile stability and reentry heating; and Bernard Budiansky, 35, who has studied the structural problems of supersonic missiles...
...nothing less than to explain the inner chemical workings of living creatures. Every living cell, including those of multicelled animals such as man, has in its nucleus large and complicated molecules that control growth and heredity. Except in some bacteria and viruses, these molecules are made of deoxyribonucleic acid (DNA), which James Watson of Harvard and Francis Crick of Cambridge, England, found to be two long chains of atoms linked together and twisted spirally. The links between the two spirals, often many thousands of them, differ slightly and constitute a sort of code that carries information and controls the heredity...
