Lan Samantha Chang was named a 2021-22 Berlin Prize fellow, awarded to scholars, writers, and artists who represent the highest standards of excellence in their field.
The famed northern and southern lights still hold secrets. In a new study, physicists led by the University of Iowa describe a new phenomenon they call “diffuse auroral erasers,” in which patches of the background glow are blotted out, then suddenly intensify and reappear.
Since taking flight in 1977, the Voyager spacecraft continue to make important discoveries. Decades after launch, the twin spacecraft are revealing secrets of the interstellar medium: the tenuous material that fills the vast space between the stars. The news feature in the scientific journal Proceedings of the National Academy of Sciences, features Donald Gurnett, professor emeritus in the Department of Physics and Astronomy at Iowa, who has been involved with the Voyager mission since its beginning.
An NPR analysis of county-level vaccination data from the CDC shows signs of an emerging rural-urban divide, especially among people who are 65 years old or older. Keith Mueller, director of the UI Rural Policy Research Institute, has been encouraging decision-makers to look beyond hospitals and chain pharmacies to get vaccines delivered to more rural communities.
A University of Iowa physicist is part of an international group of scientists that has succeeded in steering light waves deep into “forbidden” regions of photonic crystals by manipulating the shape of the waves. The technique could find use in a host of applications, including lasers, efficient solar cells, and so-called invisibility cloaks. Ravitej Uppu, assistant professor in the Department of Physics and Astronomy at Iowa, is the study’s lead author.
