When Greene became chairman of Hybritech, Inc., in January 1979, it consisted of little more than a name and some rented lab space in La Jolla. "We had a cell biologist, a protein chemist, a secretary and somebody to clean the animal cages," says Greene, "and that was about it. We had $300,000, but it looked like we were going to run dry by August...
...suppliers' products must meet the standards of the Sears product-testing labs, which are in the company's original headquarters on Chicago's West Side and in the Sears Tower. The labs were started in 1911 with a single chemist, but have evolved into a full-fledged testing organization that employs 138 engineers and technicians who run evaluations on 10,000 products annually. Mattresses are rolled over 100,000 times with a 225-lb. wooden cylinder. Leather boots spend hours dunked in pools of water or strapped to automatic walking machines. Toilets are flushed 100,000 times...
...greatest contribution has been to put ethnobiology on a solid scientific basis by being both an outstanding chemist and botanist," says Peter S. Ashton, Arnold Professor of Botany and director of the Arnold Arboretum, adding that Schultes has developed "an unusual level of capacity" to identify plants of potential economic interest. "He's demanding in the sense that he always wants the right answer, but he's also a very congenial person," says a Northeastern University professor of pharmacology, Robert Rattauf, who has worked with Schultes for the past 30 years...
Cholesterol has been perplexing researchers since 1769, when French Chemist Poulletier de la Salle first purified the soapy-looking yellow-white substance. Despite its bad reputation, cholesterol is essential to life: it is a building block of the outer membrane of cells, and it is a principal ingredient in the digestive juice bile, in the fatty sheath that insulates nerves, and in sex hormones such as estrogen and androgen. Although most of the cholesterol found in the body is produced in the liver, 20% to 30% generally comes from the food...
DIED. Joseph H. Simons, 86, chemist who discovered one of the first practical ways to synthesize fluorocarbons; of Parkinson's disease; in Gainesville, Fla. In the late 1930s, as a professor at Penn State, Simons found that passing fluorine through an arc of carbon gas produced a few drops of clear liquid fluorocarbon, but his discovery had no obvious use. A few years later, when scientists could not find enough fissionable uranium to build the Abomb, Simons rescued the jar of fluorocarbon from a filing cabinet. The resulting chemical reactions yielded highly fissionable uranium 235. By the mid-1950s...
