Crow Observatory was open June 5, 2012, for a viewing of the twice-per-century transit of Venus across the Sun. The 154-year-old Yeatman telescope projected an image of the Sun about two feet in diameter that several people could simultaneously and safely view.

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.

A new model for understanding how nerve cells in the brain control movement may help unlock the secrets of the motor cortex, a critical region that has long resisted scientists’ efforts to understand it, researchers report June 3 in Nature.

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.

WUSTL’s entry in Formula SAE, a student competition to design and drive a Formula-style race car organized by the Society of Automotive Engineers, was unveiled May 7. The car did well in competition at the Michigan International Speedway — until the last event,  where it lost its steering after the first lap of an endurance test.

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.

Eleven Washington University in St. Louis-affiliated entrepreneurs are among the winners of $750,000 in inaugural grants from Arch Grants, the global business plan competition providing $50,000 grants to startups and taking no equity in return. The 11 WUSTL-affiliated winners comprise five alumni, four faculty members and two students.

To recognize the 100th birthday of Sam Weissman, Manhattan Project scientist and beloved teacher who helped convert WUSTL’s Department of Chemistry in Arts & Sciences into a modern research department, the department is hosting a poster session, lecture and symposium Thursday and Friday, May 10 and 11.The festivities will include the second annual Weissman lecture, on the topic of the history of nuclear magnetic resonance, which will be delivered Thursday evening by Charles Slichter, PhD, emeritus professor of physics at the University of Illinois.

The Department of Mathematics has announced that a WUSTL team, consisting of senior Alex Anderson and juniors Tom Morrell and Ari Tenzer, placed 28th out of 460 teams in the demanding William Lowell Putnam Mathematics Competition. Two WUSTL teams also took first and third place in the 17th annual Missouri Collegiate Mathematics Competition. The winning team consisted of freshman Alan Talmage, and juniors Tom Moreel and Ari Tenzer.

The 2012 Spector Prize, which recognizes outstanding undergraduate acheivement in research, has been awarded to Paul Fahey, who graduated in December 2011 summa cum laude with a degree in biology. Fahey worked in the lab of Karen O’Malley, PhD, professor of neurobiology in the Department of Anatomy and Neurobiology at the School of Medicine. His thesis focused on Fragile X syndrome, the most common form of inherited mental retardation.
