Katie Westby, a vector and disease ecologist at Tyson Research Center, applies a strong DEET repellant and wears treated clothing when she’s headed deep into the woods, but uses a lighter touch at home. She warns that pet dogs and cats can also be affected by mosquito bites.

Biologists including Michael Landis in Arts & Sciences worked with researchers from dozens of countries to reconstruct the origin and global spread of butterflies. The resulting butterfly tree of life reveals that they got their start in North America.

Researchers at the McKelvey School of Engineering discovered how to use focused ultrasound with microbubbles to examine the glymphatic system. Impairments in this system may contribute to brain diseases, such as neurodegenerative diseases and stroke.

Jessie Sun, an assistant professor of psychological and brain sciences in Arts & Sciences, examines what drives good deeds.

Jr-Shin Li, a professor of systems science and mathematics at the McKelvey School of Engineering, has been named the Newton R. and Sarah Louisa Glasgow Wilson Professor of Engineering.

Rohit Pappu at the McKelvey School of Engineering received a National Science Foundation grant to study the impact of charge regulation on intrinsically disordered proteins.

Six exceptional undergraduates were recognized with Department of Biology awards, including a new prize named in honor of Garland Allen, who advocated for racial and gender equality in the biological sciences.

Research led by Peng Bai at the McKelvey School of Engineering is the first to show that a solid-state electrolyte has a high level of similarity to liquid electrolytes, which is good news for designing safer and more efficient solid-state batteries based on reliable mechanistic knowledge.

A powerful WashU-built device can squeeze and twist rocks with 100 tons of force. Geologist Philip Skemer in Arts & Sciences explains how his group is using the apparatus to better understand processes that affect the evolution of planets.

Abhinav Jha, an assistant professor at the McKelvey School of Engineering and the School of Medicine, received a National Science Foundation CAREER award to develop approaches for list-mode imaging that improve information collection.
