Science & Technology

Neuroscientists in Arts & Sciences discovered that the daily release of hormones depends on the coordinated activity of clocks in two parts of the brain, a finding that could have implications for human diseases.

Sarah Anderson, a postdoctoral research associate in biology in Arts & Sciences, won the Ruth L. Kirschstein National Research Service Award from the National Institutes of Health (NIH), a three-year fellowship valued at about $200,000.

Biologist Rachel Penczykowski in Arts & Sciences sizes up an unlikely natural phenomenon: when parasitism actually causes the number of hosts to increase, an effect known as a hydra effect. Her study of common water fleas and their fungal parasites includes laboratory components and an analysis of 13 fungal epidemics in nature.

Biomedical engineer Hong Chen at the McKelvey School of Engineering will use a $2.1 million grant from the National Institutes of Health (NIH) to find noninvasive tools to treat the brain.

Arpita Bose in Arts & Sciences, whose research is connected to carbon sequestration and sustainable bioproduction, was selected to participate in the Anant Fellowship for Climate Action, a global program for climate change “solutionaries.”

Using computer simulations and a simple theoretical model, physicist Mikhail Tikhonov in Arts & Sciences showed how bacteria could adapt to a fluctuating environment by learning its statistical regularities — for example, which nutrients tend to be correlated — and do so faster than evolutionary trial-and-error would normally allow.

St. Louis shows the strongest correlation between biodiversity and income of the 20 major U.S. cities included in a recent study. Solny Adalsteinsson, staff scientist at Tyson Research Center and a lecturer in the environmental studies program in Arts & Sciences, is a co-author of the new research published in Global Change Biology.

Eric Conners, a graduate student in in biology in Arts & Sciences, received a 2021-22 Howard A. Schneiderman Fellowship.

Sarah Anderson, a postdoctoral research associate in Petra Levin’s biology lab in Arts & Sciences, won a three-year $200,946 award from the National Institute of General Medical Sciences’ Biomedical Research and Research Training Program for a project titled “Modulation of Bacterial Cell Division by (p)ppGpp.”

White clover is a weed that grows the world over. Biologist Kenneth M. Olsen in Arts & Sciences discovered how white clover developed its anti-herbivory superpower with input from both of its seemingly innocuous parents.
