New research shows that an ancient protein that protects bacteria from bursting also helps pollen survive the dangerous transition from desiccated to hydrated once it lands on the female flower. But in pollen’s case, the protein has evolved to provide just the right amount of internal pressure: enough to power cell growth but not so much that the pollen bursts and dies.

Nobel laureate and Washington University in St. Louis alumnus William E. Moerner, PhD, will present the Weissman Lecture “Fun with Light and Single Molecules Opens Up an Amazing New View Inside Cells” at 4 p.m. Thursday, Nov. 5, in Louderman Hall on the Danforth Campus. The lecture describes the surprising techniques he and other chemists developed for imaging individual molecules, techniques that won him the 2014 Nobel Prize in chemistry. 

Falling back is easier on us than springing forward, says Erik Herzog, a biologist at Washington University in St. Louis who has devoted his career to studying body clocks and circadian rhythms. But it is never a good idea to force our body clocks to follow abrupt changes in mechanical clocks. We should get rid of daylight savings time, Herzog says.

The way our brains are wired may reveal a lot about us, according to new research co-authored by scientists at Washington University in St. Louis. For example, people with “positive” behavioral traits, such as sharp memories, many years of education and robust physical endurance, have stronger neural connections between certain brain regions than people with “negative” traits, such as smoking, aggressive behavior and a family history of alcohol abuse.

In this Q&A, program founders Rebecca Messbarger and Corinna Treitel discuss the new minor in medical humanities, the development of the field and the relationship between the arts and sciences.

The Experimental Psychology Division (Division 3) of the American Psychological Association (APA) has awarded its 2015 Lifetime Achievement Award to Larry L. Jacoby, PhD, an internationally recognized scholar of human memory and a professor of psychology in Arts & Sciences at Washington University in St. Louis.

The Department of Classics in Arts & Sciences will host a memorial for Kevin Herbert, professor emeritus of classics, at 5 p.m. Friday, Oct. 23, in the Ballroom of Washington University’s 560 Music Center.

​As a high school student in Connecticut, Sean Clarke had no idea where he would attend college. He only knew where not to go – Washington University in St. Louis. But after visiting campus, Sean decided to join his brothers, junior Matt Smith and senior Julian Clarke. 

If Republican senators from tobacco-growing southern states believe in social responsibility, they would fully explore the TransPacific (TPP) trade agreement’s potential impact on countries around the world, including provisions that influence the ability of American tobacco corporations to flood the globe with cheap, cancer-causing cigarettes, suggests the author of a book on the history, social costs and global politics of the tobacco industry.

Amy Suelzer, PhD, director of Overseas Programs in Arts & Sciences, came to Washington University in St. Louis for graduate studies in 1990, and stayed. Today, she helps guide students through the myriad study abroad programs, hoping they have the life-changing experience she did.
