A new technique developed in the lab of Matthew Lew at the McKelvey School of Engineering at Washington University in St. Louis measures the orientation of single molecules. It is enabling, for the first time, optical microscopy to reveal nanoscale details about the structures of these problematic proteins.

“This new study shows that the extinction crisis is even worse than realized,” said Jonathan Losos, the William H. Danforth Distinguished University Professor and professor of biology in Arts & Sciences at Washington University in St. Louis and director of the Living Earth Collaborative.

Research from the McKelvey School of Engineering shows that energy constraints on a system, coupled with an intrinsic property of systems, push silicon neurons to create a dynamic, at-a-distance communication that is more robust and efficient than traditional computer processors. And it may teach us something about biological brains.

The Dixit lab at Washington University in St. Louis, which in a study published in 2018 found molecular brakemen that keep the Arabidopsis Fragile Fiber 1 (FRA1) motor protein in check, uncovered in continuing research that FRA1 cinches its track in place through cellulose synthase-microtubule uncoupling proteins.

Until recently, researchers have not inspected the interplay between three common chemicals found in drinking water. Research from the McKelvey School of Engineering at Washington University in St. Louis has found they all affect each other and a closer look is needed.

An interdisciplinary team at Washington University in St. Louis used computer modeling from different domains to look at how the United States might best lift quarantine — without a harsh blow to public health or the economy.

St. Louis recently became the first jurisdiction in the Midwest — and just the fourth in the country — to adopt a comprehensive new standard designed to reduce its carbon footprint. Washington University’s Office of Sustainability provided technical expertise to support the new standard’s development.

Himadri Pakrasi, founding director of the International Center for Energy, Environment and Sustainability (InCEES) at the university, will conclude his tenure as director, effective July 1. David Fike, who has been associate director, will serve as interim InCEES director.

Undergraduates in the class “Anthropology of Infectious Diseases” in Arts & Sciences presented their findings during a remote symposium held April 22. The event was the last gathering for students in a course that became far more consequential than anyone could have predicted.

A study by biologist Amanda Koltz in Arts & Sciences at Washington University in St. Louis suggests that as female wolf spiders become larger and produce more offspring, competition among them increases — triggering higher rates of cannibalism and reducing the number of young spiders that survive to adulthood.
