It's widely known that wildfire smoke is bad for your health, but a group of researchers recently found a known carcinogen in California wildfire ash, raising concerns about just how harmful it could be to breathe the air near a blaze.
Why it matters: According to a study released in Nature Communications last week, researchers discovered dangerous levels of hexavalent chromium in samples of ash left behind by the Kincade and Hennessey fires in 2019 and 2020.
Workers in the manufacturing industry who've been exposed to elevated levels of hexavalent chromium,or chromium 6, have higher rates of lung cancer, according to the National Institute of Environmental Health Sciences.

It's widely known that wildfire smoke is bad for your health, but a group of researchers recently found a known carcinogen in California wildfire ash, raising concerns about just how harmful it could be to breathe the air near a blaze.
According to a study released in Nature Communications last week, researchers discovered dangerous levels of hexavalent chromium in samples of ash left behind by the Kincade and Hennessey fires in 2019 and 2020.
Workers in the manufacturing industry who've been exposed to elevated levels of hexavalent chromium,or chromium 6, have higher rates of lung cancer, according to the National Institute of Environmental Health Sciences.
Scott Fendorf, a professor at the Doerr School of Sustainability at Stanford University who worked on the study, said he was shocked by the results.
"Up until that point, if we had a wildfire, I was pretty cavalier about it, to be truthful. We get the alerts and I would still go outside and exercise, thinking exercise was the better factor for my health," Fendorf said.
"Now it completely changes my calculation. When we start to get wildfire warnings or smoke warnings, I'm going to be wearing an N95 mask."
In some affected areas, the study found that the concentration of chromium 6 was up to seven times that of unburned land.
Though the researchers only found hexavalent chromium in samples of wildfire ash and not wildfire smoke itself, Fendorf said they inferred that it was likely also present in the smoke. He said the team intends to collect samples from wildfire smoke in the future to test that hypothesis.
Still, the findings are especially alarming given that climate change is making wildfires burn larger and more frequently across the globe.
People in fire-prone areas are experiencing more blazes, but wildfire smoke is also floating hundreds or even thousands of miles away, affecting populations far from the flames.
Metals such as chromium naturally exist in the environment, such as in rocks like serpentinite. In this case, Fendorf said, the wildfires' intense heat appears to have transformed chromium into its hexavalent state.
"The fire changes a benign metal into a very toxic form of that metal," he said.
Hexavalent chromium is also known as the "Erin Brockovich chemical," named for the consumer advocate whose legal battle to help a small California town affected by the compound was immortalized in a now famous film starring Julia Roberts.
The Stanford team only tested ash from several areas in California, but Fendorf said the test sites contained various types of geology and vegetation, leading researchers to believe the results would be applicable to many regions across the globe.
The study's findings also open the door to further investigation of possible wildfire exposure risks for other toxic metals.

The California Science Center unveiled Tuesday the first of many launch vehicles, engines and other artifacts set to be installed in the museum’s 200,000-square-foot expansion coming to Exposition Park.
Why it matters: Jeff Rudolph, president and CEO of the California Science Center, said the $450 million expansion is California’s biggest “endeavor” yet that will inspire the next generation of scientists, engineers and explorers.
Why now: The first artifacts in the expanded museum were placed in the Kenta Kresa Space Gallery, including a three-story-tall Electron launch vehicle from Rocket Lab in Long Beach.
The backstory: It’ll be the only place in the world where visitors can see an authentic space shuttle in its “Go for Stack” position, which is what museum officials called the process of moving each of the space shuttle components into place.
What's next: Officials expect to announce next year an opening date for the expansion.

The California Science Center unveiled Tuesday the first of many launch vehicles, engines and other artifacts set to be installed in the museum’s 200,000-square-foot expansion coming to Exposition Park.
Once complete, the new Samuel Oschin Air and Space Center will include multi-level galleries built around a towering centerpiece — the space shuttle Endeavour — displayed in its 20-story vertical launch position.
It’ll be the only place in the world where visitors can see an authentic space shuttle in its “Go for Stack” position, which is what museum officials called the process of moving each of the space shuttle components into place.
Museum admission will be free.
Jeff Rudolph, president and CEO of the California Science Center, said the $450 million expansion is California’s biggest “endeavor” yet to inspire the next generation of scientists, engineers and explorers.
“The enthusiasm that people have when they come in and see this stuff and get excited about it will hopefully lead to many more people, young and old, but particularly young people wanting to pursue more education in science,” Rudolph told LAist.
Museum officials expect to announce next year an opening date, according to Rudolph.
A look inside the center
The Samuel Oschin Air and Space Center will feature three main galleries: the Samuel Oschin Shuttle Gallery, the Korean Air Aviation Gallery and the Kent Kresa Space Gallery.
Guests will be guided through hundreds of exhibits and authentic artifacts focused on the exploration of the universe — including rocket ships that carried humans into space and telescopes used to view stars and galaxies beyond our reach.

The first artifacts in the expanded museum were placed in the Kenta Kresa Space Gallery, including a three-story-tall Electron launch vehicle from Rocket Lab in Long Beach.
Adam Spice, chief financial officer of Rocket Lab, told LAist the Electron helped lower the cost of getting to space by sending satellites in smaller, cheaper rockets. The new center is an opportunity to get up close and personal with an Electron for the first time outside of a factory.
Spice said he hopes it’ll show visitors their dreams can become a reality.
“They can be part of something much bigger than probably they ever thought they could,” he said.
The first artifacts installed in the Samuel Oschin Air and Space Center include a solid rocket booster segment. Kenneth Phillips, aerospace curator, shows the scale of the piece, which has flown into space several times.

A segment of a solid rocket booster that flew into space several times is laid on its side on the second floor of the gallery.
Kenneth Phillips, the California Science Center’s aerospace curator, told LAist it’ll be turned into an interactive exhibit with audio, video and educational graphics.
“It's 12 feet in diameter, so people can actually walk through it and learn about the function of it from the inside out literally,” Phillips said.

A detailed model of a space shuttle main engine is set up next to the solid rocket booster. Three of those main engines helped boost space shuttles into orbit by providing about 20% of their power, Phillips said.
What's next
Construction of the Samuel Oschin Air and Space Center started more than three years ago and is on track to be completed in the coming weeks, according to museum officials.
With construction of the Samuel Oschin Air and Space Center weeks away from completion, crews have started to put in landscaping around the outside of the expansion.

The group of directors restoring the Village Theater in Westwood are tapping film nonprofit American Cinematheque to program and run the venue when it opens.
Why it matters: American Cinematheque also programs the Aero Theatre in Santa Monica, the Egyptian Theatre in Hollywood and the Los Feliz Theater, making it a visible and active film arts nonprofit in the industry.
The backstory: The nearly century-old movie palace went up for sale in 2024 before Village Directors Circle bought it in February. The group is comprised of more than 30 notable filmmakers. They're led by director Jason Reitman (Thank You For Smoking, Juno) and their ranks include Guillermo del Toro, Alfonso Cuarón, Lulu Wang, Chloé Zhao, Christopher Nolan and Ryan Coogler.
What's next: VDC says it's eyeing a 2027 opening for the Village Theater, and is currently in the quiet phase of a capital campaign to raise $25 million to restore and remodel the Village Theater into a more than 1,000-seat venue.

Topline:
The man accused of igniting a fire that led to the deadly and destructive Palisades Fire in January will remain in custody without bond, U.S. Judge Rozella Oliver decided Tuesday in Los Angeles. Jonathan Rinderknecht has been in custody since his arrest in Florida on Oct. 7.
Where things stand: Rinderknecht was indicted by a federal grand jury in October and is charged with one count of arson, one count of timber set afire and one count of destruction of property by means of fire. Rinderknecht pleaded not guilty in mid-October and faces anywhere from five to 45 years in federal prison if convicted. His trial is set to begin April 21, 2026. His lawyers recently asked the court to allow him out of custody as he awaits trial.
Argument against release: In a filing on Monday, prosecutors said Rinderknecht is a flight risk because of his familial ties to France, as well as a danger to the community. The filing states that Rinderknecht threatened to burn down his sister’s home and that he purchased a gun and threatened to kill his brother-in-law. Prosecutors also raised the fact that a judge determined in October that the suspect’s mental health had declined.
The allegations: Authorities allege Rinderknecht set fire to brush near the Skull Rock Trailhead in the Santa Monica Mountains at around midnight Jan. 1, starting the Lachman Fire. Though the fire was held to just 8 acres and was believed to have been extinguished, authorities say it flared up once again amid strong, dry winds a week later. That fire grew into the Palisades Fire, which killed 12 people and destroyed more than 6,800 structures.
