Joshua Blodgett, assistant professor of biology in Arts & Sciences, received a five-year $900,500 grant to support his research related to actinomycete bacteria. This type of bacteria produces a majority of current antibiotics and may harbor other useful small molecules that could be revealed by activating silent genes.

Researchers at the McKelvey School of Engineering at Washington University in St. Louis develop a method to learn more about how a new type of pesticide degrades in the environment.

Researchers from the McKelvey School of Engineering and Washington University School of Medicine in St. Louis are one step closer to delivering precise amounts of medication to exact location, repurposing an existing imaging “painting” method.

Richard Alley, the Evan Pugh Professor of Geosciences at Pennsylvania State University, will deliver the McDonnell Distinguished Lecture on March 6 at Washington University in St. Louis. Alley’s lecture is titled “Finding the Good News on Energy and Environment.”

New research from Gary Patti’s laboratory in Arts & Sciences shows that when cells divide rapidly, their mitochondria are fused together. In this configuration, the cell is able to more efficiently use oxygen for energy. This work illuminates the inner workings of dividing cells and shows how mitochondria combine to help cells to multiply in unexpected ways.

A team of engineers in the McKelvey School of Engineering has developed a high-powered fuel cell that operates at double the voltage of today’s commercial fuel cells. It could power underwater vehicles, drones and eventually electric aircraft at a significantly lower cost.

Jianjun Guan, an engineer at the McKelvey School of Engineering at Washington University in St. Louis, is developing a new material that would deliver drugs directly to the damaged part of the heart to preserve the support network.

A new study led by Petra Levin in Arts & Sciences suggests that triclosan exposure may inadvertently drive bacteria into a state in which they are able to tolerate normally lethal concentrations of antibiotics — including those antibiotics that are commonly used to treat urinary tract infections.

New research from Washington University in St. Louis shows that honey bees (Apis mellifera) develop different scent profiles as they age, and the gatekeeper bees at the hive’s door respond differently to returning foragers than they do when they encounter younger bees who have never ventured out before.
