Lots of water in the world’s most explosive volcano
Michael Krawczynski, assistant professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, and graduate student Andrea Goltz investigate the deep, inner workings of Shiveluch, a volcano on a remote peninsula in northeastern Russia.
Biden energy plan is aggressive, but much can be done
Geophysicist Michael Wysession, professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, teaches a popular undergraduate course called “Energy and the Environment.” He breaks down President-elect Joe Biden’s 9-point Energy Plan, point-by-point.
Put a flake on it: A new way to add electrical charge
Gaining control of the flow of electrical current through atomically thin materials is important to potential future applications in photovoltaics or computing. Physicists in Arts & Sciences at Washington University in St. Louis have discovered one way to locally add electrical charge to a graphene device.
Orange is the new ‘block’
New research from Washington University in St. Louis reveals the core structure of the light-harvesting antenna of cyanobacteria — including features that both collect energy and block excess light absorption. Orange carotenoid protein plays a key protective role, according to Haijun Liu, research scientist in chemistry in Arts & Sciences at Washington University in St. Louis.
Walter H. Lewis, professor emeritus in Arts & Sciences, 90
Walter H. Lewis, professor emeritus of biology in Arts & Sciences at Washington University in St. Louis, died peacefully at his home in St. Louis on Nov. 17, 2020. He was 90.
Seeking to avoid ‘full lockdown,’ cells monitor ribosome collisions
Ribosomes are the machines in the cell that use instructions from mRNA to synthesize functional proteins. When something goes awry, cells monitor for ribosome collisions to determine the severity of the problem, according to new research from Washington University in St. Louis biologists in Arts & Sciences.
China probe returns with ‘treasure trove’ of moon rocks
The Chinese space agency announced Dec. 16 the return of a lunar probe bringing back the first fresh samples of rock and debris from the moon in more than 40 years. Bradley L. Jolliff, the Scott Rudolph Professor of Earth and Planetary Sciences in Arts & Sciences at Washington University in St. Louis, reflects on the scientific value of the samples.
McKinnon honored by American Geophysical Union
Bill McKinnon, professor of earth and planetary sciences in Arts & Sciences, is one of 62 geoscientists who have been elected to the American Geophysical Union’s 2020 class of fellows.
Powerful electrical events quickly alter surface chemistry on Mars and other planetary bodies
Dust-related electrochemistry can reshape Martian surface materials with physical and chemical changes observable after only hundreds of years. Similar electrical effects may be instrumental on Venus and Europa, according to new work from Alian Wang in Arts & Sciences.
A recipe for protein footprinting
By publishing their method in the journal Nature Protocols, chemists including Michael Gross, who has a joint appointment in Arts & Sciences and the School of Medicine, have opened doors for fellow scientists to better address research questions related to Alzheimer’s disease, the COVID-19 pandemic and more.
