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.

With a new $20 million federal grant, UC Merced becomes part of a multi-institutional research collaborative to develop artificial intelligence — or AI — solutions to tackle some of agriculture’s biggest challenges related to water management, climate change and integration of new technology into farming.

President Joe Biden has nominated UC Merced Professor Asmeret Asefaw Berhe to be the new director of the Office of Science in the federal Department of Energy.

Immunology Professor Jennifer Manilay and bioengineering Professor Joel Spencer are using a new grant from the National Institutes of Health (NIH) to expand a project they’ve been working on for the past two years — delving into the immune systems of living mice to see how B-cells develop under different circumstances.

From graduate student Jose Zamora’s perspective, the CREST Center for Cellular and Biomolecular Machines (CCBM) has been a spectacular success.
