...outhouses"--Claverly, Apley, and Dudley--will likely be put in moth balls first, since they are expensive, hard to maintain and unpopular with students. They are now used for the sophomore overflow from the Houses, and for those expelled from the Houses...
...annual $1,000 prize of the American Association for the Advancement of Science went this year to Zoology Professor Carrol Milton Williams of Harvard. His research* on the hormone system that makes the native silkworm (Cecropia) turn into a moth had nothing to do with silk production; it was aimed at the central secrets of growth and life...
...tissues dissolve to form a yolky fluid. The imaginal discs wake up suddenly. Nourished by the fluid, they burst into furious growth, constructing within the larva's old skin an entirely new insect: the hibernating pupa. Later, a similar burst of growth turns the pupa into the adult moth...
Glands in the silkworm secrete the hormone which controls the production of an enzyme called cytohrome. This cytochrome is directly responsible for the growth and metamorphosis of the silkworm. Without it, the insect cannot change from caterpillar to pupa to moth. Such an enzyme in a human may be the cause of the malignant growths called cancers...
Last week Dr. Patrick D. Pielou of the Dominion Parasite Laboratory at Belleville, Ont. told how he hopes to lick this problem. Dr. Pielou breeds friendly bugs called Macrocentrus (which attack the destructive Oriental fruit moth) and exposes each generation of them to DDT not quite strong enough to wipe them out. The survivors, says Dr. Pielou, grow progressively tougher. Eventually, he hopes, they will be able to ignore DDT. Then they will be released in orchards to mop up the fruit moths that have survived...
