Media Experts on New World Screwworm

Amy M Quinton — Wed, 10 Jun 2026 10:44:36 PDT

The U.S Department of Agriculture has now confirmed cases of New World screwworm in calves and a goat in Texas and in a dog in New Mexico. New World screwworm is a serious parasitic fly that can affect livestock, pets, wildlife, and less commonly, people and birds. Adult screwworm flies are about the size of a common housefly or slightly larger. Their larvae feed on the living tissue of warm-blooded animals.

Children with Rare, Debilitating Brain Diseases Suffer From Mutations in a Little-Known Protein Complex

Andy Fell — Fri, 08 May 2026 09:40:41 PDT

Thousands of times per year, a family’s moment of joy turns to unexpected grief. A seemingly healthy infant stops smiling or making eye contact. Their limbs grow weak. The tiny child suffers seizures and breathing problems.

Jawdat Al-Bassam, an associate professor of molecular and cellular biology at the University of California, Davis, often hears from these families. “I’ve gotten emails from folks all over the world,” he said.

Climate Change Increases Spillover Risk of Rodent-Borne Arenaviruses

Katherine E Kerlin — Mon, 04 May 2026 09:00:00 PDT

Climate change is likely to drive rodent-borne arenaviruses into parts of South America that have never faced these diseases, putting new communities of people at risk, finds a study from the University of California, Davis.

For the study, published in the journal npj Viruses, scientists incorporated climate projections, shifting rodent populations and the risks of human infection into a model to offer an early risk projection for arenaviruses and other diseases in the next 20 to 40 years.

Identifying Genetic Causes of Blindness in People and Macaques

Andy Fell — Tue, 28 Apr 2026 15:25:30 PDT

An inherited form of blindness directly comparable to a common inherited optic nerve disease in humans has been discovered in rhesus macaques at the California National Primate Research Center at the University of California, Davis. The work, published April 15 in Proceedings of the National Academy of Sciences, could lead to a better understanding of autosomal dominant optic atrophy, or ADOA, and potentially to new treatments.

Global Strategies to Protect Seals and Sea Lions from Avian Influenza

Katherine E Kerlin — Thu, 19 Mar 2026 09:02:00 PDT

When the H5N1 highly pathogenic avian influenza virus was discovered on a poultry farm in Asia in 1996, there was little indication that it would become so widespread and so destructive. Within 30 years, it reached every continental region except Oceania, infecting more than 400 million poultry, tens of thousands of elephant seals and sea lions, about 1,000 people and many other mammals and wild birds.

Pinnipeds, which include seals and sea lions, have been hit unusually hard by the virus.

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

Andy Fell — Thu, 05 Mar 2026 17:22:25 PST

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.

Federal Contract for up to $40 Million Fuels Research to Revolutionize Clean Indoor Air and Defend Against Next Pandemic

Andy Fell — Thu, 16 Oct 2025 14:05:23 PDT

When a public building catches fire, its built-in systems automatically respond: Smoke alarms blare, sprinklers kick on, and occupants quickly evacuate.

But what if the life-threatening danger isn’t fire but invisible airborne contaminants that can make occupants sick? Could a similar smart-building system monitor and improve the quality of the air indoors, where Americans spend 90 percent of their time?
