Another drug made by a microscopic organism showed signs of becoming important last week. The Journal of the A.M.A. published an editorial on streptothricin, derived from Actinomyces lavendulae, a mold-like bacterium. Features of Streptothricin: 1) besides attacking many Gram-positive (blue-staining) bacteria, it attacks many of the Gram-negative (red-staining) against which penicillin is almost powerless-germs of typhoid, dysentery, etc.; 2) it is safe in therapeutic doses...
...gram of sulfadiazine a day last year protected a quarter of a million Navy men for months from a dangerous streptococcus infection which was going the rounds of the Navy, causing sore throats, scarlet fever, even meningitis. Only about one man in 1,000 had a bad reaction...
Under Dr. Florey's dynamic super vision, the blue-green penicillium mold began to grow again. The researchers dis covered that the best growing temperature is about 75° F.,that the mold needs plenty of air. At first, Dr. Florey's researchers got only about a gram of reddish-brown powder (the sodium salt of penicillin -penicillin itself is an unstable acid) from 100 liters of the mold liquid. But at last, after heroic chemical cookery, they accumulated enough penicillin to test the drug on living creatures...
...used to-but you still have a tremendous interest in the world around you-for not only do you read TIME every week, but you buy two daily newspapers as well -spend 38.4 minutes a day looking through them. You ' listen to the radio commentators (Raymond Gram Swing, Lowell Thomas and Fulton Lewis Jr. are your favorites). You own 241 books, buy eight more every year (TIME subscribers buy about one-eighth of all the adult, non-technical books sold in the U.S.). Your three favorites last year were They Were Expendable, Berlin Diary and See Here, Private Hargrove...
Modern scientists have been able to study ever smaller particles of matter. Recently the pursuit of the infinitesimal reached a new vanishing point. An R.C.A. microphysicist developed an instrument which can analyze the atomic composition of a particle as small as a millionth of a billionth of a gram...
