Kayunta Johnson-Winters, an associate professor of chemistry and biochemistry at The University of Texas at Arlington, has been named a 2025 fellow of the American Society for Biochemistry and Molecular Biology. The honor recognition recognizes her contributions to biochemistry and molecular biology and her efforts to support junior faculty, women in science and student mentorship.

In a new paper, two researchers suggest that many metamorphic proteins have an “underlying temperature dependence.” If confirmed, this would mean that temperature—and cold temperature in particular—plays a fundamental role in setting off shapeshifting in metamorphic proteins.

The Physical Chemistry Division of the American Chemical Society has named Xiaoji Xu as the winner of the prestigious 2025 Richard Van Duyne Early Career Award in Experimental Physical Chemistry.

The award recognizes outstanding contributions in experimental physical chemistry by a young investigator. Xu will accept the award and present an award lecture at the 2025 Fall ACS National Meeting.

University of Arizona astronomers have peered back to a time when the universe was just less than 300 million years old. The research team, using JWST revealed something extraordinary in the galaxy: significant amounts of oxygen.

SAN ANTONIO — March 10, 2025 — Using data collected by NASA’s Juno spacecraft as it flew past Jupiter’s highly volcanic moon Io in late 2023 and again in early 2024, a Southwest Research Institute-led team identified electrons with energies enhanced by processes in the region connecting the moon to Jupiter’s ionosphere, called an Alfvén wing. A paper published in Geophysical Research Letters emphasizes how these electrons, and their variation within that region, shape the plasma environment around Io.
