...little Hiawatha loved fireflies. So do today's kids. So, in a professional sense, do many scientists, who recognize the firefly's light as a love call-but are both baffled and fascinated by its heatless, chemically generated properties. As of last week a chemical company, Schwartz Bio-Research Inc. of Mount Vernon,N.Y.,had found a happy way of 1) letting children turn their firefly chasing to profit, 2) putting firefly tails to practical human use, and 3) offering hope that science may soon solve the longstanding puzzle of the little white-fire insect...
...market was a Schwartz offering of dehydrated firefly tails at $5 per gram as a sensitive test for ATP-adenosine tri-phosphate-a vital chemical that is found in nearly all living cells. When ATP is added to an extract of firefly tails, the solution lights up, and the amount of light given off is proportionate to the amount of ATP. By measuring the light, the ATP can itself be measured...
Died. Maurice Schwartz, 69, founder, director and leading actor of New York's Yiddish Art Theater, which from 1919 to 1950 produced about 150 plays-from Shakespeare to Sholom Aleichem-and such alumni as Paul Muni and Stella Adler; of a heart attack; in Petah Tikva, Israel...
...researchers took batches of identical mice. Into one group they injected the leukemic brain fluid. Virtually all of these developed leukemia. But a second group got an injection of purified serum from the prisoners' blood before the leukemic brain fluid. Only half of these got leukemia. Dr. Schwartz's conclusion: the prisoners, being healthy and not predisposed to leukemia, had reacted the way most normal human beings do, and had made antibodies against the leukemia virus in the brain fluid. These antibodies made their serum work like a crude vaccine, which protected half the mice...
...Hope. Other cancer experts at the meeting were impressed because, if Dr. Schwartz's work can be duplicated and confirmed, it would mark a giant stride against a disease that now kills 12,000 Americans (most of them children) annually. But Dr. Schwartz agreed that the relationship of virus to disease in leukemia must be far more complex than in common illnesses such as smallpox, influenza, measles and polio; for one thing, leukemia is not infectious. Inherited susceptibility is essential, he believes, while hormones and X rays may be important controlling factors. So, he emphasized, a vaccine against human...
