This simplification of a difficult operation was reported last week by Manhattan's Mt. Sinai Hospital. It was the first use in so delicate an operation of the "metal locator" that' helped surgeons extract pieces of shrapnel from the wounded at Pearl Harbor (TIME, Jan. 19, 1942). Although simpler and quicker than X ray, the locator (which is attached to a sensitive ammeter) had hitherto been considered too crude for such fine work. The assistant who helped the Mt. Sinai surgeon use the instrument was its inventor Manhattan Subway Engineer Samuel Berman...

Aerosol, says the Army, tracks down mosquitoes to the last, remote fold of clothing and tent. Chief producer of aerosol is Westinghouse. But Freon is still the essential spreading agent of aerosol...
...last summer, the makers found that Castoria could be made with 20% less sugar than normally. But when they started cutting, last March, they used water" that was a little different from the water used in the tests. Results: during the 45-day aging period when the laxative material (extract of senna) normally becomes oxidized to produce some substances called oxyquinones, the material lost oxygen instead, thereby developed the anthroquinones. Looking back on it now, the makers realize that the Castoria could have been fixed up by heating, longer aging, or introducing oxygen...
There are possibly three pounds of radium in the world, but accurate figures on anything to do with radium are hard to extract from the few men who control its production and sale. The price of radium has fallen from $125,000 a gram to $25,000-in terms of an ounce, a decline from $3,500,000 to $708,750. The price fell first when the carnotite mines of Colorado and again when the Belgian Congo ceased to be the only profitable sources of radium. The third break in price occurred soon after the discovery...
