As nations cut emissions that once fueled urban smog, scientists are discovering unexpected chemistry taking place in the atmosphere.

UC Merced Professor Xuan Zhang is leading a project to uncover how these chemical shifts could affect the air we breathe and the climate. The project is supported by a National Science Foundation CAREER Award.

Zhang is the 43rd researcher from UC Merced to earn a CAREER award from the NSF.

In addition to being used recreationally, marijuana and cannabidiol, or CBD, one of the cannabinoids produced by the marijuana plant, are thought to have medical benefits such as helping with chemotherapy-induced nausea, treating epilepsy, relieving pain and helping with a variety of mental health issues.

Department of Molecular and Cell Biology Professor Chris Amemiya, former interim director of the Health Sciences Research Institute, has been honored by the Pan American Society for Evolutionary Developmental Biology (PASEDB) with the Service Award.

The National Institutes of Health are backing Professor Clarissa Nobile ’s mission to understand the mechanisms by which microbes form biofilms, specifically those that can be hazardous to human health.

Two UC Merced graduate students and an alum from the School of Natural Sciences were recently awarded fellowships from the highly competitive National Science Foundation Graduate Research Fellowship Program.

This year, NSF awarded 1,000 GRFP fellowships compared to about 2,000 in previous years.

Professor Emily Jane McTavish and colleagues at the Cornell Lab of Ornithology have mapped the evolution of every known bird species.

They created a complete evolutionary tree of bird species by combining data on 9,239 species published in nearly 300 studies between 1990 and 2024 and additional curated data on another 1,000 species. The resulting database can easily be shared and updated as additional studies are published.

Pictures accompanying Professor John Abatzoglou's presentation on the 2025 fire season were blurry. That was intentional, he said, because so much about wildfire is unpredictable.

"There's a lot that we know, and a lot we don't know," he said.

When David Mendoza-Cózatl, a 2006 Pew Latin American fellow in the biomedical sciences, got an email soliciting applications for the Pew Innovation Fund, he sprang into action.

The Biology Integration Institute (BII): The Institute for Symbiotic Interactions, Training and Education in the Face of a Changing Climate, or INSITE, stands out because it is supported by $12.5 million from the National Science Foundation, one of the largest NSF grants UC Merced has ever received.

A new two-year project at UC Merced aims to bring academic and non-academic researchers together to recast the role of the humanities in public policy and, ultimately, improve the lives of San Joaquin Valley residents.

The collaborative project, entitled “Building Research Partnerships in the San Joaquin Valley: Community Engaged Research and Graduate Mentorship in the Interdisciplinary Humanities,” involves scholars and community organizations.
