Updated May 31, 2025

May 2025 brought extreme weather, big shifts in school food laws, and new wildfire technology with national implications. Northern California faced record-setting heat, triggering the rollout of live temperature risk maps, while NOAA launched a new satellite system promising wildfire alerts within one minute. Meanwhile, the state prepared for a crackdown on ultra-processed foods in public schools, and researchers warned that proposed federal Medicaid cuts could cost California over 200,000 jobs.

As we head into summer, we’ve compiled the most important stories and guides we published this month—from UC’s academic calendar changes and national park updates to AI in tax agencies and new rules for dogs in redwood country.

Our Top Four Stories from May 2025:

1) California cracks down on ultra-processed foods in schools

New rules targeting ultra-processed foods in public schools will begin rolling out this year, in what public health officials call a major shift toward preventative nutrition. Our deep-dive explains the scientific case, the policy mechanics, and how it may reshape school menus across the state.

2) NOAA launches one-minute wildfire alert system in California

With fire season arriving earlier each year, the federal government just deployed a satellite-based system that can detect wildfires within 60 seconds. Scientists say it could revolutionize response efforts—and help prevent small sparks from becoming megafires.

3) Trump’s “Alcatraz 2.0” plan hits same old roadblocks

A new proposal to reopen Alcatraz Island as a detention facility has drawn media attention and political backlash—but the logistical problems are all too familiar. From sewage systems to shark-infested waters, the island remains more symbol than solution.

4) UC endowment hits $36 billion—larger than several Ivy League schools

The University of California now manages one of the largest education endowments in the country. We examine how that money is invested, who benefits, and what it says about California’s growing financial power in public higher education.
