A research group led by Rohit Pappu in the McKelvey School of Engineering and Anthony Hyman at the Max Planck Institute have discovered a new, relevant level of structure in cells.

Camelina, an oilseed plant grown in modern-day Ukraine, may have been a more important and widespread crop than previously thought, according to collaborators from anthropology and biology in Arts & Sciences at Washington University in St. Louis. Their findings could inform breeding programs to improve this crop for biofuels applications.

A team that received early support from the Living Earth Collaborative was awarded a $633,000 grant from the U.S. Department of Agriculture to evaluate pollination in orchards across the city of St. Louis. They will examine how factors such as human population density, socioeconomic status, soil type and surrounding vegetation impact insect numbers and fruit yield.

Living Earth Collaborative postdoctoral fellow Matthew Austin published new research finding that climate change is affecting how violets reproduce.

Collaborative research from the labs of Daniel Giammar and Jeffrey Catalano finds a lack of available metals may be responsible for more nitrous oxide than previously thought.

Joan Strassmann and David Queller, both in Arts & Sciences, received a $141,578 supplemental award from the National Science Foundation for research on amoeba-bacteria cooperation.

Arts & Sciences biologists from the lab of Jonathan Myers determined that tree beta diversity — a measure of site-to-site variation in the composition of species present within a given area — matters more for the ecosystem than other components of biodiversity at larger scales.

A new modeling framework proposed by physicist Mikhail Tikhonov in Arts & Sciences demonstrates how a more complex microbial ecosystem can be more coarse-grainable, making it potentially easier for scientists to understand, than one with only a few microbes interacting.

Ethan Lowder, a December 2021 graduate who majored in the biochemistry track of biology in Arts & Sciences, won the Ralph S. Quatrano Prize; Kayla Wallace, a senior majoring in environmental biology with a minor in anthropology in Arts & Sciences, received the Spector Prize.

Research from the Living Earth Collaborative highlights the cascading consequences of common parasitic infections. Although many of these infections are not lethal, they can still impact health or animal behavior, leading hosts to eat less vegetation. The study led by biologist Amanda Koltz in Arts & Sciences is published in the Proceedings of the National Academy of Sciences.
