High-risk conditions for fires are increasingly happening across countries at the same time, making wildfires even more challenging to tackle, new research reveals.

Scientists from UC Merced and the University of East Anglia found this synchronized extreme fire weather — characterized by exceptionally warm, dry and often windy conditions — has increased strongly worldwide since 1979, becoming more widespread throughout regions, not just in single locations.

Our circadian clocks play a crucial role in our health and well-being, keeping our 24-hour biological cycles in sync with light and dark exposure. Disruptions in the rhythms of these clocks, as with jet lag and daylight saving time, can throw our daily rhythms out of whack.

But a group of researchers is getting closer to understanding how these clocks operate.

UC Merced biochemistry Professor Andy LiWang and his colleagues have solved how the circadian clocks in microscopic bacteria precisely control when different genes are turned on and off during the 24-hour cycle.

Biochemistry Professor Andy LiWang has spent much of his career studying how life keeps time. His work on the circadian clock of cyanobacteria — tiny, ancient organisms that share the planet with us — has shed light on one of biology’s most elegant systems.

But his newest research project, supported by a prestigious $1.2 million grant from the William M. Keck Foundation, pushes that inquiry into bold, uncharted territory.

UC Merced continues to demonstrate its growing influence on the global stage.

Several faculty members landed on Clarivate’s 2025 list of the world’s most‑cited researchers. The honor is reserved for the top 1% of scholars whose work has shaped their fields over the last 10 years. Clarivate, which produces journal impact factors and other analytics, says the award identifies the world’s most influential researchers.

Physics Ph.D. candidate Arabi Seshappan added two prestigious fellowships to her curriculum vitae: the Chateaubriand Fellowship in Science, Technology, Engineering Mathematics & Biology-Health and the UC President's Pre-Professoriate Fellowship.

Starting next summer, UC Merced will join an elite group of University of California campuses hosting COSMOS — the California State Summer School for Math and Science — giving some of the state’s most talented high school students a new destination for exploring advanced STEM fields.

When UC Merced launches Give to UC Merced 2025 on Dec. 2, it won’t just be about one day of giving; the month-long campaign will be about hope, opportunity and community impact.

For the 12th year, the campus joins the global Giving Tuesday movement, inviting donors to power change through the university’s UC Merced Fund. Contributions to Give to UC Merced will support the campus’s greatest needs, ensuring UC Merced has the flexibility to fund emerging opportunities, expand programs and student support initiatives, and assist promising scholars with direct financial assistance.

UC Merced researchers are collaborating on a two-year research project to develop effective composting methods for cotton textiles.

The project explores manufacturing cotton waste scraps from clothing into compost to demonstrate efficient composting with the right recipe, and the compost’s ability to nourish soils without introducing pollutants, according to UC Merced’s project lead, Biyensa Dubiwak, a postdoctoral scholar in the Department of Life and Environmental Sciences.

Professors Roger Bales and Martha Conklin arrived in Merced in 2003, the first non-administrative faculty members at UC Merced. They came with a vision: to create a research university that would serve California’s future.

Now, after more than 22 years of building institutions, mentoring and pioneering environmental research, Bales has retired from UC Merced.

Chemistry Professor Henrik Larsson has received a prestigious Early Career Award from the U.S. Department of Energy, becoming the first faculty member from UC Merced’s School of Natural Sciences to earn the honor.
