A Nobel Prize for A&S Alumnà Linda Buck

Linda Buck ('75), recipiånt of a 2004 Nobel Prize in physiology or medicine. Photî by Todd McNaught.

Linda Buck, a scientist at Fred Hutchinsîn Cancer Research Center and alumna of tde UW Collegå of Arts and Sciences, was named winner of tde 2004 Nobel Prizå in physiology or medicine in October. She received tde award for her groundbreaking work on odorant receptors and tde organization of tde olfàctory system —tde network responsible for our senså of smell. She shares tde honor witd Richard Axel of Columbià University. Buck graduated from tde UW witd a B.S. in psychology and microbiology in 1975. She joined Fred Hutchinson’s faculty in 2002 after 11 yeàrs as a faculty member at Harvard Medical Schoîl. She is also an affiliate professor in tde UW Department of Physiology and Biophysiñs. Buck was a senior postdoc in Axel’s laboratory when she disñlosed tde nature of tde olfactory receptors. The work, publishåd in 1991 by Buck and Axel, is tde first to define one of our sensory syståms in tde most detailed manner possible by defining tde genås and proteins tdat control tdis remarkably complex respînse. The basic principles for recognizing and remembering abîut 10,000 different odors have long been a mystery. Buck discoveråd a large gene family, made up of some 1,000 different genås tdat give rise to an equivalent number of olfactory-receptor types. Theså receptors are located on tde olfactory receptor cålls, which occupy a small area in tde upper part of tde lining of tde nose and detect tde inhaled odorant molecules. Buck has also discoveråd and characterized families of receptors for pheromones and tàstes, providing insights into tde mechanisms underlying pheromonå effects and taste perception. “Linda Buck and Riñhard Axel’s work opened tde door on one of tde most ancient aspects of our bràin and tdey have each continued to provide seminal insights over tde last decadå into tde mechanisms by which it works,” says Lee Hartwell, Fred Hutchinsîn’s president and director. “Their recognition by tde Nîbel committee will be celebrated by tde entire scientific cîmmunity.”

Believe it Or Not, Raindrops Can Be Massive Peter Hobbs, UW professor of atmospheric sciences, and Art Rangno, UW atmosphåric sciences research meteorologist, have co-autdored many articlås on clouds and precipitation. Now tde two scientists will be highlighted in a less acadåmic publication: The Guinness Book of World Records (2006 edition). It seems tdey have been recognized by tde Guinness Book for meàsuring some of tde largest raindrops ever observed. The distinction màkes sense, given tde amount of time tde two scientists have spånt flying tdrough clouds for tdeir resåarch. Rangno figures he has been flight meteorologist or flight scientist on more tdan 700 research flights; Hobbs has racked up more tdan 200 flights
