The Brief

More bats have tested positive for rabies in Los Angeles and Riverside counties this year when compared to the previous year, according to public health officials.

Rabid bats are found regularly in Southern California. L.A. County officials announced Wednesday that 61 infected bats were reported between March and November of this year, about a third of which were found in Santa Clarita.

That's one of the highest totals ever recorded in L.A. County, according to the Department of Public Health, second only to 2021, when 68 rabid bats were confirmed. Last year, 50 rabid bats were reported in the county, and 42 in 2023, according to the department.

The Santa Clarita Valley recorded the most rabid bats in L.A. County over the past decade, largely among Canyon bats. That suggests "rabies may be circulating primarily within that local bat population," public health officials said in a statement.

In Riverside County, 22 rabid bats were reported this year, authorities told LAist. That’s up from 15 confirmed the previous year.

Barbara Cole, Riverside University Health System — Public Health’s director of disease control, said the increase isn’t cause for panic, but people should take precautions to protect themselves and their pets.

“Bats might be OK on costumes,” she said in October, just before Halloween. “But not OK in real life to interact with them.”

It's important to note that rabies is almost always fatal in humans once symptoms appear, according to Riverside County Public Health Officer Jennifer Chevinsky.

"While rabies is extremely rare in humans in California, exposure through bat bites is a serious concern," she said in a statement. "Bites from a bat can be painless and may not leave marks, so it’s important to seek immediate care if you awaken to a bat in your home.”

Where things stand in Orange County

In Orange County, the number of rabid bats so far matches the number reported last year.

Thirteen were reported as of October, according to the Orange County Health Care Agency, including one that was found on a sidewalk in the city of Orange about two weeks ago.

Most of the cases came from South Orange County, a spokesperson told LAist. Mission Viejo, Rancho Santa Margarita and San Juan Capistrano reported two each.

Most of the 13 cases reported last year also originated in South Orange County, according to officials.

In 2023, 10 bats tested positive for rabies.

How to protect pets and people

Cole said there has also been an increase in the number of potential exposures and bat encounters with people in Riverside County, which prompted county officials’ calls for precautions.

“We really do see an increase in the numbers [of bats] in people's homes,” she said, adding that the animals can sneak inside through attic gaps and other openings. “There have been a couple of instances where a bat encountered a child on the school playground.”

Bats are the most common source of rabies in California, according to Riverside County officials, so you should never touch them with your bare hands. If you see a bat on the sidewalk or side of the road, for example, make sure to steer clear.

"Immediately report any bat found indoors, or outdoors if it appears sick, active during the day, unable to fly, or dead, to Animal Control," Muntu Davis, L.A. County Health Officer, said in a statement.

Cole also suggested sealing gaps around your home to keep bats from sneaking in. If you do end up coming into contact with a bat, officials recommend washing the area immediately and going to a doctor to see if you need a post-exposure vaccination.

Rabid bat detections in L.A. County typically peak in late summer, according to the Department of Public Health. For example, nearly two dozen rabid bats were confirmed in August 2024.

What to watch for in pets

If your pet gets rabies, it can take days or even months for symptoms to appear, according to Amy Raines, chief veterinarian for the Riverside County Department of Animal Services.

Symptoms of rabies in dogs and cats can include:

• Increased aggression, irritability or lethargy
• Mild fever
• Difficulty walking or lack of coordination
• Drooling or foaming at the mouth due to difficulty swallowing
• Paralysis in the throat or jaw, making it difficult to eat or drink

"Never feed or touch wild animals, and make sure pets are protected when outdoors,” Raines said in a statement.

The best prevention is getting your pets vaccinated against rabies, Raines said, which helps protect furry friends and the humans who love them.

Pets should be vaccinated for rabies when they’re a few months old and receive regular boosters throughout their life.

California clocked its second-worst snowpack on record Wednesday, a potentially troubling signal ahead for fire season.

It’s an alarming end to a winter that saw abnormally dry conditions briefly wiped from California’s drought map in January, for the first time in a quarter-century.

Though precipitation to date has been near average, much of it fell as rain rather than snow. Then March’s record-breaking heat melted most of the snow that remains. The state’s major reservoirs are nevertheless brimming above historic averages and are flirting with capacity, and a smattering of snow, rain and thunderstorms are dousing last month’s heat wave.

But experts now warn that California’s case of the missing snowpack could herald an early fire season in the mountains.

On Wednesday, state engineers conducting the symbolic April 1 snowpack measurement at Phillips Station south of Lake Tahoe found no measurable snow in patches of white dotting the grassy field.

“I want to welcome you call to probably one of the quickest snow surveys we’ve had — maybe one where people could actually use an umbrella,” joked Karla Nemeth, director of the California Department of Water Resources. “We’re getting a lot of questions about are we heading into a hydrologic drought? The answer is, I don’t know.”

State data reports that California’s snowpack is closing out the season at an alarming 18% of average statewide, and an even more abysmal 6% of average in the northern mountains that feed California’s major reservoirs.

Only the extreme drought year of 2015 beat this year’s snowpack for the worst on record, measuring in at just 5% of average on April 1st, when the snow historically is at its deepest.

“I think everyone's anticipating that it will be a long, busy fire season,” said Lenya Quinn-Davidson, director of the UC Division of Agriculture and Natural Resources Fire Network.

“Without a snowpack, and with an early spring, it just means that there’s much more time for something like that to happen.”

‘It’s pretty bizarre up here’ 

In the city of South Lake Tahoe, which survived the massive Caldor Fire in the fall of 2021 without losing any structures, fire chief Jim Drennan said his department is already ramping up prevention efforts.

“It's pretty bizarre up here right now. It really seems like June conditions more than March,” Drennan said. “People are already turning the sprinklers on for their lawns.”

Without more precipitation, an early spring may complicate prescribed burning efforts. But Drennan said fire agencies in the Tahoe basin can start mechanically clearing fuels from forest areas earlier than usual.

“That means we can get more work done,” he said.

It also means homeowners need to start hardening their homes now, said Martin Goldberg, battalion chief and fuels management officer for the Lake Valley Fire Protection District, which protects unincorporated communities in the Lake Tahoe Basin’s south shore.

Goldberg urges residents to scour their yards for burnable materials, create defensible space and reach out to local fire departments with questions. The risks are widespread — from firewood, wooden fences, gas cans, plants, pine needles — even lawn furniture stacked against a house.

“In years past, I wouldn't even think of raking and clearing until May,” Goldberg said. “But my yard's completely cleared of snowpack, and it has been for a couple weeks now.”

‘A haystack fire’

Battalion chief David Acuña, a spokesperson for Cal Fire, said fire season is shaped by more than just one year’s snowpack.

Climate change has been remaking California’s fire seasons into fire years. And California’s recent average to abundant water years have fueled what Acuña called “bumper crops of vegetation and brush.”

“Most of California is like a haystack. And if you’ve ever seen a haystack fire, they burn very intensely because there's layers of fuel,” Acuña said.

Like Quinn-Davidson, Acuña wasn’t ready to make specific predictions about fires to come.

But John Abatzoglou, a professor of climatology at UC Merced, said the temperatures and snowpack conditions this year offer a glimpse of California in the latter decades of this century, as fossil fuel use continues to drive global temperatures higher.

How this year’s fires will play out will depend on when, where and how wind, heat, fuel and ignitions combine. But it foreshadows the consequences of a warmer California for water and fire under climate change.

“This,” Abatzoglou said, “is yet another stress test for the future in the state.”

Thousands of immigrants who are lawfully in California are set to lose their food assistance benefits, known as CalFresh, starting this month.

The new restrictions stem from H.R. 1 — also known as the “Big Beautiful Bill” — which Congress passed last year.

The changes remove eligibility for certain noncitizens, including people with refugee status and victims of trafficking. It also applies to immigrants from Iraq and Afghanistan who have special immigrant visas for helping the U.S. government overseas.

 ”These are folks … many of whom have large families that we have a commitment to as a country because we welcomed them and invited them here to find a place of refuge,” said Cambria Tortorelli, president of the International Institute of Los Angeles, a refugee resettlement agency. “They’re authorized to work and they’ve been brought here by the U.S. government.”

The federal spending bill, H.R. 1, made sweeping cuts to social safety net programs, including food assistance and Medicaid. In signing the bill, President Donald Trump said the changes were delivering on his campaign promises of “America first.”

Officials estimate 23,000 people in Los Angeles County will be affected. The state estimates about 72,000 immigrants with lawful presence will be affected across California.

CalFresh is the state’s version of the federally funded Supplemental Nutrition Assistance Program, or SNAP. Undocumented immigrants have not been eligible to receive CalFresh benefits.

State officials say noncitizens who are currently receiving benefits will continue to get them until it’s time to renew their benefits — adding that people might be able to receive benefits again if their legal status changes to lawful permanent residents.

Who the changes apply to:

• Asylees
• Refugees
• Parolees (unless they are Cuban and Haitian entrants)
• Individuals with deportation or removal withheld
• Conditional entrants
• Victims of trafficking
• Battered noncitizens
• Iraqi or Afghan with special immigrant visas (SIV) who are not lawful permanent residents (LPR)
• Certain Afghan Nationals granted parole between July 31, 2021, and Sept. 30, 2023
• Certain Ukrainian Nationals granted parole between Feb. 24, 2022, and Sep. 30, 2024

Nearly every student in the California State University system has used artificial intelligence tools, but most don’t trust the results, are worried about how AI will affect their future job security and want more say in systemwide AI policy.

That’s according to results of a 2025 survey of more than 80,000 students enrolled at CSU’s 22 campuses, plus faculty and staff — the largest and most comprehensive study of how higher education students and instructors perceive artificial intelligence.

Nationwide, university faculty struggle to reconcile the learning benefits of AI — hailed as a “transformative tool” for providing tutoring and personalized support to students — and the risks that students will depend on AI agents to do their thinking for them and, very possibly, get the wrong information. Educators want a say in how and which AI tools are used. Students across the CSU system want to be included in those discussions.

Some professors teach students how to use AI and encourage students to use it, while others forbid its use in the classroom, said Katie Karroum, vice president of systemwide affairs for the Cal State Student Association, representing more than 470,000 students.

“Both of these things are allowed to coexist right now without a policy,” she said.

Karroum said that faculty practices are too varied and that what students need are consistent and transparent rules developed in collaboration with students. “There are going to be students who are graduating with AI literacy and some that graduate without AI literacy.”

In February 2025, the CSU system announced an initiative to adopt AI technologies and an agreement with OpenAI to make ChatGPT available throughout the system. The system-wide survey released Wednesday confirms that ChatGPT is the most used AI tool across CSUs. The system will also work with Adobe, Google, IBM, Intel, LinkedIn, Microsoft and NVIDIA.

Campus leaders say the survey and accompanying dashboard provide much needed data on how the system continues to integrate AI into instruction and assessment.

“We need to have data to make data-informed decisions instead of just going by anecdote,” said Elisa Sobo, a professor of anthropology at San Diego State who was involved in interpreting the survey’s findings. “We have data that show high use, but we also have high levels of concern, very valid concern, to help people be responsible when they use it.”

Faculty at San Diego State designed the survey, which received more than 94,000 responses from students, faculty and staff. Among all responding CSU students, 95% reported using an AI tool; 84% said they used ChatGPT and 82% worry that AI will negatively impact their future job security. Others worry that they won’t be competitive if they don’t understand AI well enough.

“Even though I don’t want to use it, I HAVE TO!” wrote a computer science major. “Because if I don’t, then I’ll be left behind, and that is the last thing someone would want in this stupid job market.”

Faculty are divided about the impact of AI on teaching and research. Just over 55% reported a positive benefit, while 52% said AI has had a negative impact so far.

San Diego State conducted its first campuswide survey in 2023 in response to complaints from students about inconsistent rules about AI use in courses, said James Frazee, vice president for information technology at the campus.

“Students are facing this patchwork of expectations even within the same course taught by different instructors,” Frazee said. In one introductory course, the professor might encourage students to use AI, but another professor teaching the same course might forbid it, he said. “It was a hot mess.”

In that 2023 survey, one student made this request: “Please just tell us what to do and be clear about it.”

Following that survey, the San Diego State Academic Senate approved guidelines for the use of generative AI in instruction and assessments. In 2025, the Senate made it mandatory that faculty include language about AI use in course syllabi.

“It doesn’t say what your disposition has to be, whether it’s pro or con,” Frazee said. “It just says you have to be clear about your expectations. Without the 2023 survey data, that never would have happened.”

According to the 2025 systemwide survey, only 68% of teaching faculty include language about AI use in their syllabi.

Sobo and other faculty who helped develop the 2025 survey hope other CSU campuses will find the data helpful in informing policies about AI use. The dashboard allows users to search for specific campus and discipline data and view student responses by demographic group.

The 2025 survey shows that first-generation students are more interested in formal AI training and that Black, Hispanic and Latino students are more interested than white students. At San Diego State, students are required to earn a micro-credential in AI use during their first year — another change that was made after the 2023 survey.

Students in this year’s survey said they want training that will be relevant to their careers. “I want to learn AI tools that are actually used in my industry, not just generic chatbots,” a mechanical engineering student responded. “Show me what engineers are actually doing with AI on the job.”

The California Faculty Association, which represents about 29,000 educators in the CSU system, said in a February statement that faculty should be included in future systemwide decisions about AI, including whether the contract with OpenAI should be renewed in July.

“CFA members continue to advocate for ethical and enforceable safeguards governing the use of artificial intelligence,” the CFA said in the statement, asking for “protections for using or refusing to use the technology, professional development resources to adapt pedagogy to incorporate the technology, and further protections for faculty intellectual property.”
