Key points:

• Researchers successfully tested a technique that uses human sewage to measure the use of nicotine products such as cigarettes and vaping pens in a selected community.

• The project, led by scientists at UC Merced, can strengthen public health efforts by supplementing surveys about nicotine use with scientific data.

• The research targeted a handful of Central Valley communities. Scientists hope to expand it to other California locations.

Five UC Merced faculty members are among the first awardees of a UC-wide honor given for exemplary research in budding academic careers.

The Early Career Faculty Research Excellence Awards, launched last fall, support commitment to scholarship and creative activity across the 10-campus system. The awards build on a range of programs and initiatives across the system designed to support thriving faculty careers at UC. 

Community voices, student research and cross-sector partnerships took center stage at the UC Merced’s Public Health Symposium, where speakers emphasized equity, access and connection as urgent priorities in the Central Valley and beyond.

On March 20, UC Merced's Center for Health Equity brought together researchers, regional health partners and community members to share findings from a study on how community health workers are transforming patient care across the San Joaquin Valley.

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.

A husband’s optimism and confidence might play a crucial, if often unseen, role in helping babies arrive healthy and on time.

A new study from UC Merced psychology researchers found that when married fathers reported higher levels of resilience — a quality that includes traits such as optimism, self-esteem and perceived social support — their partners showed lower levels of inflammation during pregnancy and carried their babies longer.

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.

The Health Sciences Research Institute (HSRI) at UC Merced is preparing to launch its long-envisioned distinguished speaker series on Oct. 6 with a visit from David Kaplan, a Tufts University professor internationally recognized for his groundbreaking work in bioengineering.

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.
