The U.S. Senate lost one of its staunchest defenders and most influential leaders with the death Monday, June 28, of long-serving Democratic Sen. Robert Byrd of West Virginia. “The death of Robert Byrd is important,” says Steven S. Smith, a congressional expert at Washington University in St. Louis. “He was first and foremost a senator. He loved the Senate and was the strongest defender of its traditions.”

It’s no secret that Americans tend to throw their support behind a sitting U.S. president when the nation is thrust into a war or other potentially violent conflict with a foreign foe. But new research from Washington University in St. Louis is the first to show that these “rally effects” represent a collective reaction to a specific human emotion – anger.

Friends and colleagues of Owen Sexton, PhD (right), professor emeritus of biology in Arts & Sciences and former director of Tyson Research Center, joined him June 17 at the facility to thank him for his mentorship and for advocating the purchase of the research center, WUSTL’s 2,000-acre field station in the Ozark foothills 20 miles outside of St. Louis.

Scientists once thought the fertilization effect of rising carbon dioxide concentrations would offset factors such as higher temperatures or drier soils that would reduce crops yields. This view is turning out to be overly optimistic. A new study shows that soybeans switch into unproductive metabolic activity at higher carbon dioxide concentrations. The invasive cheatgrass, on the other hand, has no switch, or control, and continues to efficiently transport water and assimilate carbon. Crop plants might need to be equipped with similar traits to survive future arid high-carbon dioxide environments.

When it comes to executing items on tomorrow’s to-do list, it’s best to think it over, then “sleep on it,” say psychologists at Washington University in St. Louis. The researchers have shown that sleep enhances our ability to remember to do something in the future, a skill known as prospective memory.

Celebrated jazz pianist, composer and arranger Linda Presgrave and her quintet will launch “Jazz in July,” a series of free summer concerts presented by Washington University’s Jazz at Holmes, from 8 to 10 p.m. Thursday, July 8.

Arts & Sciences recognized the achievements of six alumni during the 13th Annual Arts & Sciences Distinguished Alumni Awards Ceremony, held April 29 at the Ritz-Carlton, St. Louis. A new tradition was started this year with the addition of an awards dinner hosted by Gary S. Wihl, PhD, dean of the faculty of Arts & Sciences and the Hortense and Tobias Lewin Distinguished Professor in the Humanities, and the Arts & Sciences National Council.

A memorial tribute for Richard E. Norberg, PhD, retired professor and longtime chair of physics in Arts & Sciences, will be held at 4 p.m. Tuesday, June 1, in Crow Hall, Room 201. A reception will follow in Compton Laboratory, Room 241.

A seven-year experiment shows that pond communities bear the imprint of random events in their past, such as the order in which species were introduced into the ponds. This finding locates one of the wellsprings of biodiversity but also suggests that it may not be possible to restore ecosystems whose history we cannot recreate.
