...science's deepest mysteries is what makes living creatures grow and what makes most of them stop growing as they reach maturity. In Nature, Professor Carroll M. Williams of Harvard describes research that may cast light on this basic mystery. He has extracted from mammalian tissues a "golden oil" that, injected into a caterpillar, stops its development and prevents its transformation into a butterfly...
...juvenile hormone may prove to be a substance that controls growth in mammals as well as insects. But so far Dr. Williams has not isolated the pure hormone or determined its chemical character, points out that its presence in mammalian tissues may be only a biochemical curiosity...
...superintendent of schools in Petersburg, Mich., at one point also coached the boys' basketball team. She began teaching at the U. of Michigan in 1920, during her years there wrote and edited some of medicine's basic works on neuroanatomy, gathered probably the largest collection of sub-mammalian and mammalian brains in the world. At Ann Arbor, she earned a sparkling set of honorary degrees and a sentimental tag from student physicians: "Angel of the medical school...
...color of stagnant water" has been transformed by Hollywood into a dreamy-looking cinemactor named Paul Newman-but Newman's performance as Ben Quick, before the script blunts it, is as mean and keen as a cackle-edge scythe. And Eula Varner, she of the "kaleidoscopic convolution of mammalian ellipses," is divided into two slender young beauties named Lee Remick and Joanne Woodward-but Woodward plays her part with a fire and grace not often seen in a movie queen. And old Will Varner, "thin as a fence rail and almost as long," is transmogrified into the Falstaffian figure...
...these days, science may come to the rescue. Geneticist Manuel Gordon of Michigan State University has succeeded in partially controlling the sex of unborn rabbits. His system depends on the fact that when a mammalian ovum is fertilized, the sex of the individual into which it will develop is determined by the sperm that does the fertilizing. Half the sperm cells have X chromosomes, which produce females. The other half have Y chromosomes, which produce males. So a way to start to control sex might be to separate the sperm cells into X and Y fractions before insemination...
