RFK Jr. said his agency will find the cause of autism. These researchers have actually been looking

The annual meeting of the International Society for Autism Research took place in Seattle this week.

The field’s premiere scientific conference was scheduled to be held in the Emerald City five years ago, until COVID-19 dashed those plans. This time, U.S. autism researchers face a very different kind of crisis: massive cuts to federal funding, Cabinet members making false statements about the complex neurological condition they study, and a series of confusing and potentially worrisome policy announcements about autism research.

In April, the U.S. Department of Health and Human Services disclosed that it’s planning a $50-million “comprehensive research effort aimed at understanding the causes of [autism spectrum disorder] and improving treatments,” a department spokesperson said. The effort was spurred by Secretary Robert F. Kennedy Jr.’s stated goal of determining the cause of autism, a neurological and developmental condition whose symptoms cluster around challenges with communication, social interaction and sensory processing.

At his first news conference last month, Kennedy made a number of scientifically inaccurate statements about autism: that it is preventable (there is no evidence that it is); that studying its genetic underpinnings is a “dead end” (genes play a significant role); that children with autism “will never hold a job” (autism presents in myriad different ways and many autistic people work) and, perhaps most significantly, that “we know it’s an environmental exposure” (this is, to put it mildly, far from an established fact.)

On Thursday, an HHS spokesperson said that the agency was developing “a secure data repository” of “large-scale, de-identified data to better understand the causes of conditions like autism and chronic diseases,” similar to the National Cancer Institute’s Surveillance, Epidemiology, and End Results Program.

This was a clarification of National Institutes of Health Director Dr. Jay Bhattacharya’s statement during an April 21 meeting with NIH advisors that the study would draw in part from personal health information gathered across a variety of sources, including insurance claims, pharmacy chain medication records and fitness tracker data, a plan widely reported as an “autism registry.”

HHS has otherwise offered minimal detail on the research effort, which Kennedy initially said would return results as early as September. (Bhattacharya has since pushed back on that timeline, saying that grants would only start to go out to participating researchers by the end of summer.)

A half-dozen senior scientists interviewed for this article said that neither they nor anyone they knew of had been consulted.

“I’m someone who knows a lot of people in this field,” said Helen Tager-Flusberg, professor emerita at Boston University and director of its Center for Autism Research Excellence, and “not a single person I know has been approached.”

Tager-Flusberg is a member of HHS’ Interagency Autism Coordinating Committee, which advises the agency and Congress on autism research. Since Trump took office in January, she said, the committee has not received any communications from HHS, and has not been informed or consulted about the latest research initiative.

“With one hand, [Kennedy‘s] offering $50 million in new research, and with the other hand, they have already removed a significantly large number of grants that are already carrying out cutting-edge research on autism,” she said. “NIH has invested hundreds of millions of dollars into [studying] causes of autism over the last three decades, and so it’s disturbing to hear that it’s all being dismissed.”

The U.S. government is by far the nation’s biggest investor in autism research. In 2019 and 2020, the most recent period for which data are available, federal grants totaling $350 million supported 82.5% of U.S. autism research, with the remainder coming from private sources.

“Federal funding is the engine by which research runs, and it is certainly the engine by which autism research has made the incredible advances that it has over the last 25 years,” said Matthew Lerner, an associate professor at Drexel University’s AJ Drexel Autism Institute and a board member of the International Society for Autism Research.

Several researchers also said that they found Kennedy’s insistence that autism stems from exposure to an undetermined environmental source perplexing. The role of environmental factors in autism is already a major focus area for government-funded research, they said, albeit in a more nuanced way.

When scientists speak of “environmental exposures,” they are referring to any nongenetic influence before or after birth. These can range from prenatal stress hormones to neighborhood pollutants to the school a child attends.

“Any scientist will tell you that this is such a complex thing that you can’t just be looking at one [cause], that you have to be thinking about the role of environment, the role of genetics, how they interact, and how that changes over the lifespan,” said Alycia Halladay, chief science officer of the nonprofit Autism Science Foundation. “We do know that there are a lot of environmental exposures that have not been studied. We can’t say it is an environmental toxin.”

Dr. Shafali Jeste was more blunt.

“This is what we dedicate our lives to,” the Los Angeles pediatric neurologist said. “If we knew there could be one environmental cause, wouldn’t we all be out there hunting for it, and maybe having already found it, given that we’ve been doing research for 20 years?”

The cuts and chaos of the second Trump administration are already having an affect on the research community.

Several people interviewed for this article asked not to be quoted by name for fear of retaliation, or specified that they could only speak on behalf of themselves and not their employer, at the institution’s request.

In late April, Tager-Flusberg founded the Coalition of Autism Scientists, a group of senior researchers united around the shared goals of pushing back on disinformation and advocating for evidence-based research approaches.

More than 200 fellow scientists signed up immediately, she said. But when younger researchers have asked to join, she has discouraged them from doing so. Speaking out could cost them their jobs.

“I don’t really have anything to lose,” she said. But “the last thing I would want is to put anyone’s career in jeopardy.”

Owners of mobile home park destroyed in the Palisades fire say they’re finally clearing the debris

Owners of mobile home park destroyed in the Palisades fire say they’re finally clearing the debris

Former residents of the Palisades Bowl Mobile Home Estates, a roughly 170-unit mobile home park completely destroyed in the Palisades fire, received a notice Dec. 23 from park owners saying debris removal would start as early as Jan. 2.

The Bowl is the largest of only a handful of properties in the Palisades still littered with debris nearly a year after the fire. It’s left the Bowl’s former residents, who described the park as a “slice of paradise,” stuck in limbo.

The email notice, which was reviewed by The Times, instructed residents to remove any burnt cars from their lots as quickly as possible, since contractors cannot dispose of vehicles without possessing the title. It followed months of near silence from the owners.

“The day before Christmas Eve … it triggers everybody and throws everybody upside down,” said Jon Brown, who lived in the Bowl for 10 years and now helps lead the fight for the residents’ right to return home. “Am I liable if I can’t get this done right now? Between Christmas and New Year’s? It’s just the most obnoxious, disgusting behavior.”

Brown is not optimistic the owners will follow through. “They’ve said things like this before over the years with a bunch of different things,” he said, “and then they find some reason not to do it.”

Earlier this year, the Federal Emergency Management Agency denied requests from the city and the Bowl’s owners to include the park in the U.S. Army Corps of Engineers cleanup program, which FEMA said was focused on residential lots, not commercial properties. In a letter, FEMA argued it could not trust the owners of the Bowl to preserve the beachfront property as affordable housing.

The Bowl, which began as a Methodist camp in the 1890s, was purchased by Edward Biggs, a Northern California real estate mogul, in 2005 and split between his first and second wives after his death in 2021. The family has a history of failing to perform routine maintenance and seeking to redevelop the park into a more lucrative resort community.

After FEMA’s rejection, the owners failed to meet the City of L.A.’s debris removal deadlines. In October, the city’s Board of Building and Safety Commissioners declared the park a public nuisance alongside seven other properties, giving the city the authority to complete the debris removal itself and charge the owners the bill.

But the city has yet to find funds to front the work, which is expected to cost millions.

On Dec. 10, City Councilmember Traci Park filed a motion that would order the city to come up with a cost estimate for debris removal and identify funding sources within the city. It would also instruct the city attorney’s office to explore using criminal prosecution to address the uncleared properties.

The Department of Building and Safety did not immediately respond to requests for comment.

Despite the recent movement on debris removal, residents of the Palisades Bowl still have a long road ahead.

In mobile home parks, tenants lease their spaces from the landowners but own the homes placed on the land. Before residents can start rebuilding, the Bowl’s owners need to replace or repair the foundations for the homes; fix any damage to the roads, utilities and retaining walls; and rebuild facilities like the community center and pool.

The owners have not responded to multiple requests for comment, but in February, Colby Biggs, Edward Biggs’ grandson, told CalMatters that “If we have to go invest $100 million to rebuild the park and we’re not able to recoup that in some fashion, then it’s not likely we will rebuild the park.”

Mobile home law experts and many residents doubt that the Biggs family would be able to convert the rent-controlled mobile home park into something else under existing law. The most realistic option, should the Biggs decide against rebuilding, would be to sell the park to another owner — or directly to the residents, a course of action the residents have been actively pursuing.

The lack of communication and action from the owners has nonetheless left the Bowl’s eclectic former community of artists, teachers, surfers, first responders and retirees in limbo.

Many are running out of insurance money for temporary housing and remain unsure whether they’ll ever be able to move back.

Commentary: ‘Stop exercising, you’re killing yourself.’ Not really, but try more nurture, less torture in 2026

Commentary: ‘Stop exercising, you’re killing yourself.’ Not really, but try more nurture, less torture in 2026

One day my left foot hurt for no good reason. I stood up to shake off the pain and tweaked my right Achilles tendon, so I headed for the medicine cabinet, bent over like an ape because of a stiff back.

Actually, I lied.

It wasn’t one day. It’s pretty much every day.

None of this is severe or serious, and I’m not complaining at the age of 72. I’m just wondering.

Are my exercise routines, which were meant to keep me from falling apart, slowing my demise, or accelerating it?

What better time than the start of a new year to get an answer? In one poll, the top New Year’s resolution for 2026 is exercising more. Also among the top six resolutions are eating healthier, improving physical health and losing weight, so good luck to all you dreamers, and I hope you last longer than I have with similar resolutions.

Instead of a resolution, I have a goal, which is to find a sweet spot — if there is one — between exercise and pain.

Maybe I’m asking too much. I’ve had two partial knee replacements, I’ve got a torn posterior cruciate ligament, a scar tissue knob on a frayed Achilles tendon, a hideously pronated left foot, a right shoulder that feels like it needs an oil change, and a pacemaker that keeps on ticking.

But I decided to get some expert advice that might be useful for anyone who has entered this glorious phase of life in which it’s possible to pull a muscle while taking a nap, or pinch a nerve in your neck while brushing your teeth.

And I knew just whom to call.

Cedars-Sinai orthopedic surgeon Robert Klapper hosts an ESPN radio show called “Weekend Warrior.” This lab-coated Renaissance man, a surfer and sculptor in his spare time, also weighs in regularly on the radio with “Klapper Vision” — clear-eyed takes on all manner of twisted, pulled and broken body parts suffered by elite athletes and banged-up buzzards like me.

On “Weekend Warrior,” Klapper might be talking about knee replacement surgery one minute, segue to Michelangelo’s rendering of the human form, and then insist that a sandwich is not a sandwich without peperoncini. It isn’t necessarily all connected, but it doesn’t matter.

When I emailed Klapper about my aches and pains, he responded immediately to say he’s written one book on hips, another on knees and a third one is in the works with the following title:

“Stop Exercising, You’re Killing Yourself.”

No, he’s not saying you should never get off the sofa. In a phone conversation and later at his office, Klapper said the subtitle is going to be, “Let Me Explain.” He’s making a point about what kind of exercise is harmful and what kind is helpful, particularly for people in my age group.

My daily routine, I told him, involves a two-mile morning walk with my dog followed by 30 minutes of swimming laps or riding a stationary bike.

So far, so good.

But I also play pickleball twice a week.

“Listen, I make a living from pickleball now,” Klapper said. “Exercise is wonderful, but it comes in two flavors.”

One is nurturing, which he calls “agercise” for my demographic.

The other is abusive, and one of Klapper’s examples is pickleball. With all its starts and stops, twists and turns, reaches and lunges, pickleball is busting the Medicare bank, with a few hundred million dollars’ worth of injuries each year.

I know. The game looks pretty low key, although it was recently banned in Carmel-by-the-Sea because of all the racket. I had no idea, when I first picked up a paddle, that there’d be so much ice and ibuprofen involved, not to mention the killer stares from retirees itching for a chance to drill you in the sternum with a hot laser.

“This is a sport which has the adrenaline rushing in every 50-year-old, 60-year-old, 80-year-old,” Klapper told me in his office, which is the starting point in his joint replacement factory. The walls are covered with photos of star athletes and A-list Hollywood celebrities he’s operated on.

“I see these patients, but they’re not coming to me with acute injuries. They didn’t snap their Achilles tendon … like they do in tennis. They’re not snapping their ACL like they are in pickup basketball,” Klapper said. “They’re coming to me saying, ‘My shoulder is killing me, my knee is killing me.’ ”

Pickleball has obvious conditioning benefits for every age group. But it can also worsen arthritis and accelerate joint degeneration, Klapper said, particularly for addicts who play several times a week.

Not that he’s the first MD to suggest that as you age, walking, cycling and swimming are easier on your body than higher-impact activities. As one doctor said in an AARP article on joint care and the benefits of healthy eating, watching your weight and staying active, “the worst thing you can do with osteoarthritis after 50 is be sedentary.”

Still, I thought Klapper might tell me to stop pickling, but he didn’t.

“Pickleball is more than a sport to you … and all of your compadres,” he said. “It’s mental. You need it because of the stress. The world’s falling apart.… I want you to play it, but I want you to do the nurturing exercises so you can do the abuse.”

There’s no fountain of youth, Klapper said, but the closest thing is a swimming pool.

OK, but I already swim three times a week.

Klapper had different ideas.

“You need to be walking forward and backwards for half an hour,” he said. Do that three times a week, he told me, and ride a stationary bike three times.

Why the water walking?

“We as humans take over a million steps a year. Forget pickleball, just in … daily living,” Klapper said, so I’m well beyond 72 million steps.

“Think about that,” he said.

Do I have to?

Water walking will develop muscles and joints without the stress of my full weight, and that could “optimize” my pickleball durability and general fitness, Klapper said. Buoyancy and the touch of water on skin are magic, he said, but there’s science involved too.

“It’s hard to move your arms and legs and your body through water, and yet it’s unloading the joint,” Klapper said. “And finally — and this is the real X factor — when you close your eyes and straighten your elbow and bend your elbow, straighten your knee and bend your knee … your brain knows where your limbs are in space.”

This is called proprioception, Klapper said. Receptors in your skin, muscles, ligaments and tendons send messages to your brain, leading to better balance, coordination and agility and potentially reducing risk of injury.

There are lots of exercises for sharpening proprioception, but the surfing doctor is partial to bodies of water. At my age, he said, my proprioception “batteries are running low,” but I can recharge them with a short break from pickleball and a focus on the pool.

“You can’t guarantee anything in life and medicine,” Klapper said. “But I guarantee you, a month into it, you’re going to feel so much better than you do at this moment.”

It’s worth a try, and I’ll let you know how it goes.

In the pool and on the court.
