CHEMISTRY COMMUNITY SWARMS INTO WINDY CITY

Two times each year, legions of chemists gather in North America for a massive meeting to discuss the state of the art in their science. The second of this year's get-togethers occurred 2 weeks ago, when the 20 6th national meeting of the American Chemical Society (ACS) drew about 13,000 chemists, scientists, and onlookers to Chicago. Researchers sh ared 4800 or so papers and posters on everything from making waste pla stic into fuel oil to the chemical basis for the stench of ginkgo frui t to modeling the first instants of photosynthesis.
