...last week: a new synthetic drug called Antrycide, to cure and prevent trypanosomiasis (related to sleeping sickness) in cattle. The drug will be used in a vast area of Africa, larger than the U.S., where profitable ranching has long been impossible because of tsetse flies which carry the wiggly protozoan parasite of trypanosomiasis to domestic cattle, horses and hogs...
...researchers have looked long for a specific poison secreted by cancer cells. If such a substance could be detected in a cancer patient's blood, early diagnosis should be easy. Roskin started by testing the effect of serum from cancerous mice on the sensitive paramecium, a single-celled protozoan.* The serum had no effect. But when it was inactivated by freezing, and then mixed in carefully measured proportions with healthy guinea-pig serum, the mixture developed a toxic factor which killed paramecia...
...Grigori Roskin of Moscow University casually picked up an article on South America's fatal Chagas' disease, a protozoan infection spread chiefly by an acorn-sized insect, the triatoma. In female Chagas victims there is a wasting away of breast tissues, which are composed of large, spongy cells. Could it be, Dr. Roskin wondered, that the devouring parasitic trypanosomes are especially attracted to large cells? And that cancerous tissues, which are also made up of oversized cells, might also succumb to the same parasite...
French critics have been exclaiming and declaiming about Author La Mazière. His hero, the Parisian equivalent of a Wall Street protozoan, is made to seem more wistful than the meanest Americano would likely be. An orphan, he suffers an ugly seduction in his youth. His one love affair founders on his poverty before it is launched. His friends are a kindly, resigned fatalist, and a mad painter who drags him to hear opera from the top gallery. His sensitive nature is sickened by the War and after the misery of heroism he experiences peacetime betrayal by crass noncombatants...
...shot felled a yellow-headed vulture, which had swooped upon a spectacled owl, which had clenched (and been hugged dead by) an anaconda, which had bolted a basha (torpedo-shaped fish), which had snapped up a pok-poke (smoky jungle frog), in whose food canal lived an opalina (irridescent protozoan covered with hairlike flagella). Explorer William Beebe, who fired the shotgun, indicates this chain of life with his dissecting knife, philosophizing as he studies Nature in the steaming jungle of British Guiana. Other chapters-creeping, rustling, whirring, crashing, oozing with live things-centre on an inverted, deaf, lethargic, odorless, whistling...
