Frank J. Stadermann, Ph.D., senior research scientist in physics in Arts & Sciences at Washington University and a sample adviser for NASA’s Stardust mission will discuss his research team’s significant find from the Stardust mission, the first U.S. space mission dedicated to the exploration of a comet, and the first robotic mission designed to return extraterrestrial material from outside the orbit of the Moon.

It’s long been assumed that people are willing to pay more for an item if they know a portion of the proceeds will go to charity. But do they really? Two professors from the Olin School of Business at Washington University in St. Louis collected data from eBay auctions.

Scientists have identified the first biochemical marker linked to sleep loss, an enzyme in saliva known as amylase, which increases in activity when sleep deprivation is prolonged. Researchers hope to make amylase the first of a panel of biomarkers that will aid diagnosis and treatment of sleep disorders and may one day help assess the risk of falling asleep at the wheel of a car or in other dangerous contexts.

Peanut butter is energy rich food, and it doesn’t spoil. That’s exactly why WUSM pediatrician Mark Manary chose it to nourish hungry children in Malawi.
