Science & Technology

Researchers working with Randall Martin at the McKelvey School of Engineering quantified changes in global air pollution from fine particulate matter. They found that global PM2.5 exposure decreased steadily from 2011 to 2019, largely driven by rigorous air quality management in China and slower growth in other regions.

Atmospheric scientists led by Jian Wang, at the McKelvey School of Engineering, analyzed data from an Arctic expedition and found that blowing snow is a source of sea salt aerosols, impacting Arctic climate models.

Bradley Jolliff in Arts & Sciences is part of the team that will develop the surface science plan for Artemis III, the first crewed lunar landing mission in more than 50 years.

Washington University’s new Center for the Environment begins its work, another step forward in the “Here and Next” strategic plan.

Jessica Wagenseil, a professor of mechanical engineering and materials science and vice dean for faculty advancement in the McKelvey School of Engineering, has been elected a fellow of the Biomedical Engineering Society.

Erik Henriksen, an associate professor of physics in Arts & Sciences, is part of a team that was awarded funding from the National Science Foundation’s Quantum Sensing Challenges for Transformational Advances in Quantum Systems program.

Chenfeng Ke, an incoming associate professor of chemistry in Arts & Sciences, developed a unique design for tough but stretchable hydrogels, reported Aug. 23 in the journal Chem. The new material is both flexible and durable.

Volcanic eruptions can cause the Pacific Walker Circulation to temporarily weaken, inducing El Niño-like conditions. Human activity is affecting this system, too.

Ramesh Agarwal, a professor of mechanical engineering & materials science, and Yixin Chen, a professor of computer science and engineering, both in the McKelvey School of Engineering, have been elected as fellows of the Asia-Pacific Artificial Intelligence Association (AAIA), an interdisciplinary organization of AI industries.

A study from biologist Elizabeth Mallott in Arts & Sciences highlights a critical development window during which racial differences in the gut microbiome emerge. Early social and environmental exposures can have large and lasting effects on child development and adult health.
