Dark matter and the life cycles of star clusters will come into focus as UC Merced’s astrophysicists get resources from the two space telescopes soon to be exploring the universe.

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.

UC Merced’s largest research grant in its 16-year history aims to improve agricultural and environmental water resilience. The new $10 million collaborative focuses on water banking, trading and improvements in data-driven management practices to arrive at a climate-resilient future in water-scarce regions of the United States.

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.

Shortly before the fall semester kicked off in person, 11 students were wrapping up their first summer on campus as part of the FACTS summer bridge program.

FACTS stands for San Joaquin Valley Food and Agriculture Cyberinformatics Tools and Science. The six-week summer course, funded by the United States Department of Agriculture’s (USDA) National Institute of Food and Agriculture, introduces students to the world of research in agricultural science and technology.

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.

More than a few students have probably asked themselves why they have to take calculus — the course is notoriously difficult for some.

“People haven’t been taught math the way it should be,” Department of Applied Mathematics Professor Mayya Tokman said. “Math is practical. It’s there to solve problems and answer questions. But somehow, we lost that, and math is now taught as an abstract.”

While the campus remained quieter than usual this summer, a group of new graduate students began their UC Merced journey earlier than the rest of their cohort.

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.

It has been 186 years since Charles Darwin collected the samples of the Galapagos Islands species that led to his explanation of how the diversity of life on Earth has evolved and forever changed the way we understand the world.

During his five-week stay on the islands, Darwin collected dozens of samples, including one small, light brownish-grey snake on Floreana Island. That sample, now at the Natural History Museum in London, was the basis for describing a new species, the Galapagos (Floreana) racer.
