National Academy of Sciences Elects UC Davis Maize Geneticist Jeffrey Ross-Ibarra

Andy Fell — April 29, 2026 - 8:45am

The National Academy of Sciences has elected Jeffrey Ross-Ibarra, professor in the Department of Evolution and Ecology at University of California, Davis, as a member. His election was announced April 28.

Ross-Ibarra is one of 120 members and 25 international members elected this year in recognition of distinguished and continuing achievements in original research. Membership in the academy is considered one of the highest honors a scientist can achieve.

Fish Evolution Accelerated After Adapting to Eat off Hard Surfaces

Andy Fell — April 28, 2026 - 1:47pm

Why are there so many species of coral reef fish? According to a new study, it’s because about 50 million years ago, some fish figured out how to bite food from hard surfaces.

Evolution doesn’t proceed at an even pace: Species evolve in jumps and spurts, followed by lulls. These periods of rapid diversification usually occur after a dramatic environmental change or upheaval, or when a lineage develops a new “innovation” that allows them to use a previously inaccessible resource. For fish, the ability to feed from a hard surface was one such innovation.

Stop-and-Go Science: Researchers Pivot to Try to Salvage Important Work

When climate change is faster than the speed of science and unstable funding threatens discovery, UC Davis scientists pivot to try to save important research.

How Curiosity and Mentorship Shaped Dean Mark Winey’s Scientific Journey

Anila Mary Lijo — March 31, 2026 - 10:37am

For Mark Winey, the path into biology was deeply personal from the start. Watching his sister live with an inherited metabolic disease sparked a curiosity about genetics that would shape his entire career.

He is this month’s guest on Face to Face With Chancellor May.

A Billion Daily Repairs: How Our Cells Mend Broken DNA

Andy Fell — March 23, 2026 - 10:45am

A major new discovery could inspire improved treatments for cancer and genetic diseases.

Coiled within our cells are fragile threads of DNA that contain the codes of life— determining when each of our 30 trillion cells must grow, divide, sit tight — or simply die. This arrangement is precarious. Billions of times per day, our DNA is severed by stray chemical reactions. Our cells must rebuild the broken DNA without making mistakes – or the consequences can be dire.

Plant Cell Structure Could Hold Key to Cancer Therapies and Improved Crops

Andy Fell — March 05, 2026 - 5:22pm

Can the bend of a banana give us insight into cancer? What does the shape of a rice grain have to do with infertility? The proteins that give plants their shape and structure are also involved in human disease. A team led by researchers at the University of California, Davis, has mapped out the structure of a key player, augmin, in exhaustive detail.

A Gene Editor That’s a Better Fit for Plants

Andy Fell — February 20, 2026 - 12:09pm

Gene editing has enormous potential to help feed the world’s growing population, but it’s currently difficult, time-consuming, and only works in some plant species. A big part of the problem is CRISPR/Cas9’s size: it’s too large to be delivered into plant cells.

Mirror Image Pheromones Help Beetles Swipe Right

Andy Fell — February 18, 2026 - 5:26pm

There are many ways to communicate with prospective romantic partners: If you are a Japanese scarab beetle, it’s a matter of distinguishing left from right. New work from U.S. and Chinese scientists, published this week in Proceedings of the National Academy of Sciences, shows how these beetles use mirror-image pheromones to find a mate. The work could lead to better monitoring and control of significant agricultural pests.
