Research into Hidden Chemistry Shaping Future Air Quality Earns Zhang an NSF Award

September 8, 2025

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...

Past Wildfires Offer Future Roadmap for Forest Management’s Effects on Water

Forest restoration is often associated with mitigating wildfire risk and improving ecosystem health throughout the Sierra Nevada. But restoration also dramatically affects water use within forests...

Professor Tracey Osborne Taking on Complex, Grand Challenges in Climate and Social Justice

The world is a complex place, and humanity faces major challenges. Climate change mitigation might be the most difficult, in large part because of the interdependency of living things and their...

Global Fire Outlook Not Good News, but Mitigation is Possible, Analysis Shows

Wildfire is a natural process necessary to many ecosystems. But wildfires are getting worse and more damaging, and it is our fault, according to new research. A paper by two UC Merced researchers...

Freeing the state from its dependence on fossil fuels means finding the right combination of renewable solutions, as well as efficient, low-cost energy storage.

New Project Shining a Light on Energy Storage

California’s leaders want the state to reach 100 percent clean energy in the future, including being 60 percent powered by renewable energy by 2030 and being free of fossil fuels entirely by...

Reforesting After Wildfires: Which Trees Are Most Likely to Thrive?

Wildfire seasons are intensifying because of climate change. That means reforestation efforts will increase, making it important for scientists and resource managers to understand how to make sure...

Ecosystem Engineers Play Crucial Role in Stabilizing Their Environments, Study Shows

When people think of engineering in nature, they tend to think of species such as beavers — the tree-felling, dam-building rodents whose machinations can shape the landscape by creating lakes...

World’s Oldest Trees Shape the Diversity of Life in Their Soils, Study Shows

There’s a whole world of activity beneath your feet. Soil holds a large proportion of Earth's biodiversity, and is the place where organisms interact with each other and with plants,...

New Engineering Research Center to Focus on Agriculture Technology

By 2050, the U.S. population is estimated to grow to 400 million, and the world population to 9.1 billion, requiring a 70 percent increase in global food production. UC Merced is one of four...
