Katherine E Kerlin — May 05, 2026 - 1:19pm

After months of fieldwork and scientific analysis, National Park Service researchers have determined that the coyote that drew international attention in early 2026 after swimming to Alcatraz Island likely started his epic swim from Angel Island State Park.

The coyote’s whereabouts remain unknown, but new DNA evidence has helped park staff answer one of the biggest questions surrounding the unusual sighting: where he came from.

Climate Change Increases Spillover Risk of Rodent-Borne Arenaviruses

Katherine E Kerlin — May 04, 2026 - 9:00am

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 — April 28, 2026 - 3:25pm

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.

Families could, for a while, spend less time worrying about money and more time being a family, according to new University of California, Davis, research.

The program provided a monthly stipend to 76 mostly single-parent families between 2022 and 2024, helping them gain housing, food and general wellbeing for two years.

New Research Suggests FDA Should Consider Redesign of Proposed Nutrition Labels

Karen Michele Nikos-Rose — March 24, 2026 - 9:20am

Packaged foods offer convenience for families and individuals, but they can be a major source of saturated fat, sodium and added sugars, which when consumed in excess contribute to chronic disease. To help people build healthier diets, the U.S. Food and Drug Administration proposed a new front-of-package nutrition label in January 2025 that would inform consumers about the presence of these nutrients.

Global Strategies to Protect Seals and Sea Lions from Avian Influenza

Katherine E Kerlin — March 19, 2026 - 9:02am

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.
