Twelve of UC Merced’s graduate programs and one of its schools are among the best in the country in the U.S. News & World Report 2023 Best Graduate Schools rankings, according to results released March 29.

Graduate students who are passionate about their research, concerned about the environment and eager to reach across disciplinary boundaries are invited to apply for a three-week summer program in which they will team up with like-minded scientists and engineers to design solutions to environmental sensing challenges.

Theoretical chemist Professor Aurora Pribram-Jones has been named a Cottrell Scholar, winning one of only 24 of the prestigious $100,000 grants for her proposal entitled “Reframing Interaction in Quantum Mechanical Ensembles and Across Chemistry Learning Communities.”

Human waste isn’t a topic most people want to talk about.

But environmental systems Professor Rebecca Ryals embraces the subject, especially when it comes to mitigating climate change, improving public health and creating sustainable food systems.

Graduate students and a convergence of physics, engineering and environmental science could result in not only the next generation of solutions to pressing environmental challenges, but a new group of diverse and globally competitive nano-engineers, as well.

A nearly $2 million grant from the National Science Foundation (NSF) will train about 200 graduate students over the next five years as they learn and work to develop nano-sensors to better manage resources.

An HIV-inhibiting silk film designed to advance prevention and help end the AIDS epidemic in countries in Africa, developed by UC Merced Professor Patti LiWang, has met recent success at the California National Primate Research Center at UC Davis.

“They show complete protection,” LiWang said. “The films worked perfectly on the macaques at Davis.”

Daily cycles in virtually every aspect of our physiology are driven by biological clocks (also called circadian clocks) in our cells. The cyclical interactions of clock proteins keep the biological rhythms of life in tune with the daily cycle of night and day, and this happens not only in humans and other complex animals but even in simple, single-celled organisms such as cyanobacteria.

Cartilaginous fishes such as sharks and skates have a sixth sense, but it’s not ESP — it’s electrosense. Such fishes use hundreds or thousands of specialized organs to sense prey and mates and to navigate the oceans.

A cross-disciplinary group of researchers at UC Merced is making new discoveries about the fundamental structure of the organs and how this structure may provide clues as to how this sixth sense works.

Like many people this summer, Professor Shahar Sukenik has dehydration on his mind.

But it’s not the soaring outside temperatures prompting this focus. Dehydration has been a theme of his lab’s work for the past year, from understanding how seeds know when to germinate to a new grant to further knowledge about the proteins that help protect cells and organisms against irreversible drying.

The over the counter, “safe,” organic-compliant insecticides people purchase at home-improvement stores could be causing a problem that goes far beyond the vegetable garden or farm field — antibiotic resistance.
