Diversity plays a key role in maintaining the stability of plant and animal life in an area. But it’s difficult to scale up smaller experiments to understand how changes will impact larger ecosystems. A new study of North American birds from biologists in Arts & Sciences reveals the importance of both total numbers and variation in species identities.

Stan Braude, a biologist in Arts & Sciences, published a new study in the African Journal of Ecology that considers the role of the moon in driving a particularly rare occurrence: the solo journey of a naked mole rat from one underground colony to start a new one.

In this video, Washington University in St. Louis’ Michael Vahey discusses what it takes for a virus such as the coronavirus to reach pandemic status.

A collaboration between the McKelvey School of Engineering and St. Jude Children’s Research Hospital uncovers the underlying rules that, when broken, contribute to neurodegenerative diseases such as ALS.

Researchers from Washington University in St. Louis and the Chinese Academy of Agricultural Sciences discovered that rice domestication relied on selection for traits determined by a poorly understood portion of the rice genome.

New research from Washington University in St. Louis provides insight into how proteins called phytochromes sense light and contribute to how plants grow. Biologists used sophisticated techniques to structurally define the sequence of events that support the transition between light- and dark-adapted states.

Want to help stop the decline of our insect friends? A new publication from Brett Seymoure in Arts & Sciences shows how artificial light at night negatively impacts thousands of species that have evolved to use light levels as cues for courtship, foraging and navigation.

Arpita Bose, assistant professor of biology in Arts & Sciences, has published new work that reveals how one kind of bacteria “eats” electricity by pulling in electrons straight from an electrode source. The research is published Nov. 5 in mBio.

A Washington University in St. Louis expert on circadian rhythms says the country should be on standard time permanently. The science behind the choice is clear: standard time is better in terms of sleep, cardiac function, weight, cancer risk and alcohol and tobacco consumption.

Himadri B. Pakrasi, professor of biology in Arts & Sciences and director of InCEES, was recently awarded a $1.2-million grant for a collaborative study of cyanobacteria with the ultimate purpose of producing nitrogen-fixing crop plants.
