Most organisms on this planet rely on a circadian clock to function properly. New research published by biologists in Arts & Sciences investigates how an internal clock helps nitrogen-fixing cyanobacteria accommodate seemingly conflicting processes within a single cell.

Stan Braude, a professor of practice in biology and in environmental studies in Arts & Sciences, died at home June 1, 2024. Braude was the first curator of the university’s arboretum and a world expert on naked mole-rat ecology, evolution and behavior in the wild.

Researchers at Washington University in St. Louis combine artificial intelligence and mobile health data to better predict recovery from lumbar spine surgery.

A study from biologists and clinicians at Washington University in St. Louis reports that glioblastoma cells have built-in circadian rhythms that create better times of day for treatment.

Washington University’s new National Academy of Sciences members are Michael S. Diamond, MD, PhD, the Herbert S. Gasser Professor of Medicine at the School of Medicine, and David C. Queller, the Spencer T. Olin Professor of Biology in Arts & Sciences.

Undergraduates Hannah Davis, Shelei Pan, Braxton Sizemore and Shan Wang were honored by the Department of Biology in Arts & Sciences at Washington University in St. Louis.

Being a predator has its own costs, and that’s as true for amoebae as it is for lions or wolves. Graduate student P.M. Shreenidhi joined David Queller and other Art & Sciences researchers to study the predatory nature of a particular soil-dwelling amoeba.

Yunfeng Ge is an avid bird and nature lover. Her extensive research and volunteer work has prepared her for life after graduation. She plans to pursue conservation work and eventually attend graduate school to study ecology.

Jianjun Guan, a materials scientist in the McKelvey School of Engineering at Washington University in St. Louis, received a four-year more than $2 million grant from the National Institutes of Health (NIH) to design a system of nanoparticles that deliver drugs after a heart attack much more effectively than current methods allow.

In a paper published in ACS Nano, researchers at Washington University in St. Louis outline how they used a chemical probe to light up interlocking peptides. Their technique will help scientists differentiate synthetic peptides from toxic types found in Alzheimer’s disease.
