The taste of love: what turns male fruit flies on

Scientists at Washington University in St. Louis have found a gene that seems to unleash the courtship ritual in male fruit flies. Males missing this gene are capable of courtship; they just have trouble getting started. Usually male fruit flies are “highly sexed,” to the point that they will court and mount “perfumed dummies,” decapitated females coated in waxy pheromones.

Glides like balsa

Parkway South High School senior Will Mertz explains the design of his team’s custom-built hand glider to Chris Kroeger, associate dean for students in the School of Engineering & Applied Science, during the Boeing Engineering Challenge May 4 in the Athletic Complex Field House. Mertz was among some 80 area high school students in 24 teams competing in the Boeing Challenge to determine which team’s glider had the farthest flight, straightest path, longest hang time or highest quality of flight.

The need for speed

Sophia Hayes, associate professor of chemistry in Arts & Sciences, was an undergraduate at the University of California, Berkeley, leaning toward an economics major when she stumbled into a quantum mechanics class and then a chemistry class with a collaborative research focus. Research projects were the hook, and “I crammed the chemistry major into my last two years,” Hayes says.
