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.

An international team of astronomers has studied ultramassive galaxies - galaxies containing more than 100 billion stars - as they existed when the universe was less than 2 billion years old. The results show that while some of these ultramassive galaxies, or UMGs, had already shut down star formation and become extremely dust-poor, others exhibit ongoing or residual activity that is obscured by dust, revealing multiple evolutionary pathways for the most massive galaxies.

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.

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.

Kathy Chau believed she knew what her future would look like. The first in her family to attend college, she had long been advised to aim for a safe and stable job — one that might not light a fire in her soul but would pay the bills.

“I resigned myself to working a corporate job. I didn't like the sound of it, but I didn't hate it, either,” she said.

When Professor Asmeret Asefaw Berhe arrived at UC Merced in 2009, she and her husband, Professor Teamrat Ghezzehei, were leaving major research institutions to join a brand-new campus in California’s Central Valley. It was a leap of faith — one made easier by the Sierra Nevada Research Institute.

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.
