...speech, sponsored by the History Department, was followed by a panel discussion with Jane Jenson of Carleton University, Cora Kaplan of Rutgers University and Susan Pedersen, an assistant professor of history at Harvard...
Before the families receive their ration of food, the children are examined by health workers. Their eyes are peered at; their skin is checked. The aides take measurements of each child. If he or she is too small, it can be a sign of chronic malnourishment. Danish Nutritionist Birthe Pedersen, who works for the International Committee of the Red Cross, is measuring an eight-year-old boy. The upper part of his sticklike arm is 9.8 cm around; a normal child's arm is about 15 cm. After the boy walks away, Pedersen looks grim. "He will not live very...
...chemistry award went to two Americans, Charles J. Pedersen, 83, now retired from Du Pont, and Donald J. Cram, 68, of the University of California, Los Angeles, and French Chemist Jean-Marie Lehn, 48. The three were cited for their work, dating back as far as the 1960s, in creating artificial molecules that can mimic the behavior of hormones and other organic substances. The lone winner in medicine was Susumu Tonegawa, 48, a Japanese-born molecular biologist at M.I.T. His contribution: showing how a handful of genes in a small number of immune cells turn out a staggering variety...
...just won the Nobel Prize for Chemistry. Reason: Cram is in the rug-shampooing business. The Swedish Academy of Sciences had rung up the wrong man. Quipped UCLA Chemist Donald J. Cram after hearing about the mix-up: "There is some chemistry involved in carpet cleaning." Cram, Pedersen and Lehn, working independently, shared the award for their work in "host-guest" chemistry. "The basis of our work," explains Lehn, "is the way molecules are able to recognize each other." In nature, molecules that work together have complementary shapes, like a lock and a key, and only the right key will...
...essence of the work was the discovery of crown-ethers made by Pedersen several years ago," said Frank B. Baird, Jr. Professor of Science Dudley R. Herschbach, who won the Nobel Prize in chemistry last year. "Cram and Lehn were among the leaders in following up Pedersen's work...
