Just as rising gasoline prices are forcing many Americans to tighten their financial belts, new research suggests higher fuel costs may come with a related silver lining — trimmer waistlines. “An additional $1 in real gasoline prices would reduce obesity in the U.S. by 15 percent after three years,” said Charles Courtemanche, an economics doctoral student in Arts & Sciences.

Sexton observes a flooded Marais Temps Clair.In science, it’s best to be good, but sometimes it’s better to be lucky. Ecologist Owen Sexton, professor emeritus of biology in Arts & Sciences at Washington University in St. Louis, had just completed a census of snakes at a conservation preserve northwest of St. Louis, when the great flood of 1993 deluged the area, putting the preserve at least 15 feet under water. The flood provided Sexton with a rare opportunity: his collected data and the flood would combine to make “the perfect study” of how an area rebounds from natural disaster.

The coconut has been popular in lore and on palates for centuries, yet little is known about the history of this palm’s domestication and dispersal around the world. Now, Kenneth M. Olsen, Ph.D., assistant professor of biology in Arts & Sciences, is embarking on the task of understanding the plant’s history by exploring the genetics of the coconut.
