  • Tests in homes near Eaton Fire show lingering lead
    An aerial view of properties cleared of fire debris that burned in the Eaton Fire seen on July 7, 2025 in Altadena.

    Topline:

    After the Eaton Fire, many homes remained standing but were coated with the ashes of structures that burned. Post-fire testing showed these surviving homes contained lead, asbestos and other heavy materials that pose a risk to human health.

    On Thursday, a group of residents released results from a new round of testing. The findings show contaminants remain present in many homes, even after professional cleaning.

    A second opinion: Francois Tissot, a Caltech geochemistry professor who was not involved in the effort, said the results are concerning. “I personally was expecting that the values post-remediation in most houses would look really good,” Tissot said. But lead levels on the floors of 63% of tested homes were found to be far above EPA screening thresholds, a result Tissot called “worrying.”

    Digging into the data: The results came from 50 homes in the Altadena area. The data was compiled by Eaton Fire Residents United, a group that formed after January’s historically destructive fire. Ten of those homes had been included in the group’s previous release of pre-remediation testing data.

    Read on… to learn what we still don’t know, and what concerned homeowners can do.

    After the Eaton Fire, many homes remained standing but were coated with the ashes of structures that burned. Post-fire testing showed these surviving homes contained lead, asbestos and other heavy materials that pose a risk to human health.

    On Thursday, a group of residents released results from a new round of testing in dozens of homes. The findings show contaminants remain present in many homes, even after professional cleaning.

    Francois Tissot, a CalTech geochemistry professor who was not involved in the effort, said the results are concerning.

    “I personally was expecting that the values post-remediation in most houses would look really good,” Tissot said.

    Instead, 63% of tested homes had lead on their floors at levels far above EPA screening thresholds.

    It’s a result Tissot called “worrying.”

    Digging through the data

    The results came from 50 homes in the Altadena area. The data was compiled by Eaton Fire Residents United, a group formed after January’s historically destructive fire. Ten of those homes had been included in the group’s previous release of pre-remediation testing data.

    Most of the homes (78%) in the latest round of testing had been cleaned by a professional remediation company. The other 22% were do-it-yourself jobs performed according to public health recommendations.

    The testing was performed by various licensed industrial hygienist testing companies, and it was paid for either by insurance providers or out-of-pocket by homeowners. Only about half the homes were tested for asbestos.

    The lack of consistency across testing is one of the limitations inherent in figuring out ongoing health risks, said Nicole Maccalla, the resident group’s data science director.

    “There is a need for standards in this industry,” Maccalla said.

    About one-third of the cleaned homes (36%) that were checked for asbestos tested positive. Not every home was tested for the presence of heavy metals. But among six homes that were, all returned positive results for chromium, barium, copper and zinc.

    Homes near Eaton Fire burn zone still test positive for lead and asbestos — even after cleaning

    Dawn Fanning, the resident group’s managing director, said regulators should take these results seriously because asbestos has been linked with lung cancer, lead has been linked with neurological problems (especially in children and pregnant women), and heavy metals can cause kidney and liver damage, among other health issues.

    “We don't want to alarm people, but we don't want them to live in unsafe homes,” Fanning said. “This is why we're asking elected officials to roll up their sleeves, get involved and do what needs to be done to make sure that every home is safe.”

    Is normal cleaning enough?

    Organizers from the group said they want elected officials to ensure homes are tested and fully clear of contaminants before residents are told to return. They said until full clearance is achieved, insurance companies should be required to extend relocation benefits for displaced residents.

    Tissot, the Caltech scientist, said more data is needed to fully understand the health risks present in cleaned homes. For example, he said children living in the area should be given blood tests for lead.

    Tissot said his own lab plans to test remediated homes for the presence of harmful substances, independent of the Eaton Fire Residents United project. He said it’s possible that cleaning standards that are sufficient in rural areas may not be enough to fully clean homes where thousands of structures burned.

    “Most of those protocols are established based on wildfires which do not contain a very high amount of heavy metals to begin with,” he said. “But maybe the cleaning protocols are insufficient for urban fires.”

    Eaton Fire Residents United leaders, who have been navigating their own path toward cleaning their homes, recommend that concerned homeowners run HEPA air filters and leave shoes outside.

    Those precautions are a start, but they say it’ll take advocacy — and pushing insurance companies to cover post-remediation testing — for homeowners to feel confident about re-entering a healthy home.

  • The airport will close in 2028 to become a park

    The Santa Monica Airport will close in 2028 and become a sprawling public park.

    Topline:

    The Santa Monica Airport will close in 2028 and become a sprawling public park that city officials say will improve quality of life and boost green space.

    What we know: The city is in the very early stages of planning how to transform the 192 acres into a park. The preliminary report shows some potential amenities of the park, such as gardens, biking trails, art galleries, a community center and much more.

    Background: After a long legal battle between the city and the Federal Aviation Administration, a settlement was reached that ruled that the city could close the more than 100-year-old airport. The park was controversial among residents because of air quality and noise concerns, and was the subject of many legal battles in recent decades.

    What’s next? The city wants to hear from residents. You’re encouraged to review the framework and fill out this survey. Feedback will be accepted until April 26.

    Thousands of immigrants, including refugees and asylees, in California are set to lose their food assistance benefits, known as CalFresh, starting this month.

    Topline:

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

    What’s new: The changes apply to certain immigrants who are here lawfully, including refugees and asylees. It also applies to people from Iraq and Afghanistan who have special visas for helping the U.S. military overseas.

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

    What’s next: Officials estimate 23,000 people in Los Angeles County will be affected. 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.

    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
  • Students mistrust results and fear job impact

    Topline:

    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.

    CSU AI survey: CSU polled more than 94,000 students, faculty and staff, making it the largest survey of AI perception in higher education. Nearly all students have used AI but most question whether it is trustworthy. Both faculty and students want more say in systemwide AI policies. Faculty are divided about the impact of AI on teaching and research. 

    The results: 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. In addition to clarity around use of AI policies, 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.”

    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.”

    Tennis courts featured in an April Fools' Day social media post by Irvine.

    Topline:

    Many Southern California cities and institutions are dropping big, grabby news today — from the city of Irvine going "pickle-ball" only, to the Huntington Botanical Gardens announcing it'll be bottling the scent of the famed corpse flower as a perfume.

    Why now: Before you go "what the what" — remember today's the first day of April.

    Read on ... to find a roundup of some of the April Fools' jokes from your city and local trusted institutions.

    Many Southern California cities and institutions are dropping big, grabby news today. Before you go "what the what" — remember, it's the first day of April.

    Here's a roundup of some of the April Fools' news dump items.

    Irvine, the 'pickleball-only' city

    Irvine announced that it'll be converting all tennis courts into pickleball courts by 2027. That's one notch for Team Pickleball in the ongoing turf war between tennis lovers and pickleball players over the fight for court space to engage in their beloved sport.

    "Starting today, April 1, all tennis courts are being converted to pickleball courts as part of a citywide effort to make Irvine a pickleball-only City by 2027," the post stated. "We don’t just think this is a good idea … we dink it’s a great one."

    Catch that? They "dink" it's a great idea.

    All hail Queen Latifah in Long Beach

    Over in Long Beach, Mayor Rex Richardson announced the city's reigning royalty, the Queen Mary, will be renamed after another queen.

    "After careful consideration, I am proud to announce that the Queen Mary will officially be renamed the RMS Queen Latifah," he said. "Long Beach is stepping into a new era as a major music destination — with a new amphitheater, a deep cultural legacy, and a future built on sound. It’s only right that our most iconic Queen reflects that energy."

    In real-real news, LBC native and everyone's favorite Olympics commenter Snoop Dogg is headlining the grand opening show of the Long Beach Amphitheater in June. That's the new waterfront venue near the RMS Queen Latifah.

    Prolific author gets his own library branch

    Suspense writer James Patterson has more than 200 novels to his name, selling more than 450 million copies. If anyone deserves his own namesake branch, it would be Patterson, no?

    The Los Angeles Public Library certainly dinks so, announcing today the James Patterson Canoga Park branch, "with wall to wall Patterson books and programming centered around this prolific author."

    Eau de corpse flower

    The opening of the corpse flower has become an annual event at the Huntington Botanical Gardens. The event brings legions hoping to get a whiff of the famed flower's "pungent aroma."

    The San Marino institution announced that it's bottling the scent, as part of its new "The Huntington's Stank Collection."

    "A musky gym sock note opens this unique fragrance, with a sweet, rotten-egg base to ground it. Smells like you – but smellier," the post explained.

    Adopt something you can just leave at home, always

    Pasadena Humane got in on the fun with a special event — today only — where you can adopt a rock.

    "Adoption ROCKS! And today only, you can adopt a friend you won't take for granite," the message said.
