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.

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.

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.

The same cellular renewal that keeps our bodies healthy might also fuel the growth of cancer. A UC Merced biologist has found that the brain could hold the key to stopping it.

A team of scientists led by UC Merced is embarking on a project to understand how the twisted shapes of specific molecules can influence the spin of electrons — a phenomenon that could revolutionize solar energy, electronics and quantum computing.

The research, funded by the U.S. Department of Energy’s Scientific Discovery through Advanced Computing (SciDAC) program, focuses on a mysterious effect known as chirality-induced spin selectivity, or CISS.
