Health insurance premiums for 1.7 million Californians on Obamacare will soar as federal subsidies end
Californians renewing their public health plans or who plan to sign up for the first time will be in for sticker shock when open enrollment begins on Saturday. Monthly premiums for federally subsidized plans available on the Covered California exchange — often referred to as Obamacare — will soar by 97% on average for 2026.
The skyrocketing premiums come as a result of a conflict at the center of the current federal government shutdown, which began on Oct. 1: a budgetary impasse between the Republican majority and Democrats over whether to preserve enhanced, Biden-era tax credits that expanded healthcare eligibility to millions more Americans and kept monthly insurance costs affordable for existing policyholders. About 1.7 million of the 1.9 million Californians currently on a Covered California plan benefit from the tax credits.
Open enrollment for the coming year runs from Nov. 1 until Jan. 31. It’s traditionally the period when members compare options and make changes to existing plans and when new members opt in.
Only this time, the government shutdown has stirred uncertainty about the fate of the subsidies, first introduced during the COVID-19 pandemic and which have been keeping policy costs low, but will expire at the end of the year if lawmakers in Washington don’t act to extend them.
Californians window shopping on the exchange’s consumer homepage will have to make some tough decisions, said Covered California Executive Director Jessica Altman. The loss of the tax credits to subsidize premiums only adds to what can already be a complicated, time-consuming and frustrating process.
Even if the subsidies remained intact, premiums for plans offered by Covered California were set to rise by roughly 10% for 2026, due to spikes in drug prices and other medical services, Altman said.
Without the subsidies, Covered California said its members who receive financial assistance will see their monthly premiums jump by an additional $125 a month, on average, for 2026.
The organization projects that the cost increases will lead many Californians to simply go without coverage.
“Californians are going to be facing a double whammy: premiums going up and tax credits going away,” Altman said. “We estimate that as many as 400,000 of our current enrollees will disenroll and effectively be priced out of the health insurance that they have today. That is a devastating outcome.”
Indeed, the premium spike threatens to lock out the very Americans that the 2010 Affordable Care Act — President Obama’s signature domestic policy win — was intended to help, said Altman. That includes people who earn too much to qualify for Medicaid but who either make too little to afford a private plan or don’t work for an employer that pays a portion of the premiums.
That’s a broad swath of Californians — including many bartenders and hairdressers, small business owners and their employees, farmers and farm workers, freelancers, ride-share drivers, and those working multiple part-time gigs to make ends meet. The policy change will also affect Californians who use the healthcare system more frequently because they have ongoing conditions that are costly to treat.
By raising the tax-credit eligibility threshold to include Americans earning more than 400% of the federal poverty level, the Biden-era subsidies at the heart of the budget stalemate have brought an estimated 160,000 additional middle-income Californians into the system, Covered California said. The enhanced subsidies save members about $2.5 billion a year overall in out-of-pocket premium expenses, according to the exchange.
California lawmakers have tried to provide some relief from rising Covered California premiums by recently allocating an additional $190 million in state-level tax credits in next year’s budget for individuals who earn up to 150% of the federal poverty level. That would keep monthly premiums consistent with 2025 levels for a person making up to $23,475 a year, or a family of four bringing in $48,225 a year, and provide partial relief for individuals and households making slightly more.
Altman said the state tax credits will help. But it may not be enough. Forecasts from the Urban Institute, a nonprofit research group and think tank, also show a significant drop-off of roughly 400,000 enrolled members in Covered California.
The national outlook is even worse. The Congressional Budget Office warned Congress nearly a year ago that if the enhanced premium subsidies were allowed to expire, the ranks of the uninsured would swell by 2.2 million nationwide in 2026 alone — and by an average of 3.8 million Americans each year from 2026 to 2034.
Organizations that provide affordable Obamacare plans are preparing for Californians to get squeezed out of the system if the expanded subsidies disappear.
L.A. Care, the county’s largest publicly operated health plan, offers Covered California policies for 230,000 mostly lower-income people. About 90% of the Covered California consumers they work with receive subsidies to offset their out-of-pocket healthcare insurance costs, said Martha Santana-Chin, L.A. Care’s CEO. “Unless something drastic happens … a lot of those people are going to fall off of their coverage,” Santana-Chin said.
That outcome would ripple far and wide, she said — thanks to two factors: human behavior and basic economics.
If more and more people choose to go uninsured, more and more people will resort to visiting hospital emergency rooms for non-emergency care, disrupting and overwhelming the healthcare system.
Healthcare providers will be forced to address the cost of treating rising numbers of uninsured people by raising the prices they bill to insurers for patients who have private plans. That means Californians who are not Covered California members and don’t receive other federal healthcare aid will eventually see their premiums spike too, as private insurers pass any added costs down to their customers.
But right now, with the subsidies set to end soon and recent changes to Medicaid eligibility requirements threatening to knock some of the lowest-income Californians off of that system, both Altman and Santana-Chin said their main concern is for those who don’t have alternatives.
In particular, they are concerned about people of color, who are disproportionately represented among low-income Californians, according to the Public Policy Institute of California. Any hike in out-of-pocket insurance costs next year could blow the budget of a family barely getting by.
“$100, $150, $200 — that’s meaningful to people living on fixed incomes,” Altman said. “Where is that money coming from when you’re living paycheck to paycheck?”

The federal SNAP-funding mess has made L.A.’s food-insecurity crisis clearer than ever
A strange scene unfolded at the Adams/Vermont farmers market near USC last week.
The pomegranates, squash and apples were in season, pink guavas were so ripe you could smell their heady scent from a distance, and nutrient-packed yams were ready for the holidays.
But with federal funding in limbo for the 1.5 million people in Los Angeles County who depend on food aid from the Supplemental Nutrition Assistance Program — or SNAP — the church parking lot hosting the market was largely devoid of customers.
Even though the market accepts payments through CalFresh, the state’s SNAP program, hardly anyone was lined up when gates opened. Vendors mostly idled alone at their produce stands.

As thousands across Southern California lined up at food banks to collect free food, and the fight over delivering the federal allotments sowing uncertainty, fewer people receiving aid seemed to be spending money at outdoor markets like this one.
“So far we’re doing 50% of what we’d normally do — or less,” said Michael Bach, who works with Hunger Action, a food-relief nonprofit that partners with farmers markets across the greater L.A. area, offering “Market Match” deals to customers paying with CalFresh debit cards.
The deal allows shoppers to buy up to $30 worth of fruit produce for only $15. Skimming a ledger on her table, Bach’s colleague Estrellita Echor noted that only a handful of shoppers had taken advantage of the offer.
All week at farmers markets where workers were stationed, the absence was just as glaring, she said. “I was at Pomona on Saturday — we only had six transactions the whole day,” she said. “Zero at La Mirada.”
CalFresh customers looking to double their money on purchases were largely missing at the downtown L.A. market the next day, Echor said.

“This program usually pulls in lots of people, but they are either holding on to what little they have left or they just don’t have anything on their cards,” she said.
The disruption in aid comes as a result of the Trump administration’s decision to deliver only partial SNAP payments to states during the ongoing federal government shutdown, skirting court order to restart funds for November. On Friday night, Supreme Court Associate Justice Ketanji Brown Jackson temporarily blocked the order pending a ruling on the matter by the U.S. Circuit Court of Appeals.
But by then, CalFresh had already started loading 100% of November’s allotments onto users’ debit cards. Even with that reprieve for food-aid recipients in California, lack of access to food is a persistent problem in L.A., said Kayla de la Haye, director of the Institute for Food System Equity at USC.
A study published by her team last year found that 25% of residents in L.A. County — or about 832,000 people — experienced food insecurity, and that among low-income residents, the rate was even higher, 41%. The researchers also found that 29% of county residents experienced nutrition insecurity, meaning they lacked options for getting healthy, nutritious food.
Those figures marked a slight improvement compared to data from 2023, when the end of pandemic-era boosts to state, county and nonprofit aid programs — combined with rising inflation — caused hunger rates to spike just as they did at the start of the pandemic in 2020, de la Haye said.
“That was a big wake-up call — we had 1 in 3 folks in 2020 be food insecure,” de la Haye said. “We had huge lines at food pantries.”
But while the USC study shows the immediate delivery of food assistance through government programs and nonprofits quickly can cut food insecurity rates in an emergency, the researchers discovered many vulnerable Angelenos are not participating in food assistance programs.
Despite the county making strides to enroll more eligible families over the last decade, de la Haye said, only 29% of food insecure households in L.A. County were enrolled in CalFresh, and just 9% in WIC, the federal nutrition program for women, infants and children.
De la Haye said participants in her focus groups shared a mix of reasons why they didn’t enroll: Many didn’t know they qualified, while others said they felt too ashamed to apply for aid, were intimidated by the paperwork involved or feared disclosing their immigration status. Some said they didn’t apply because they earned slightly more than the cutoff amounts for eligibility.
Even many of those those receiving aid struggled: 39% of CalFresh recipients were found to lack an affordable source for food and 45% faced nutrition insecurity.
De la Haye said hunger and problems accessing healthy food have serious short- and long-term health effects — contributing to higher rates of heart disease, diabetes and obesity, as well greater levels of stress, anxiety and depression in adults and children. What’s more, she said, when people feel unsure about their finances, highly perishable items such as fresh, healthy food are often the first things sacrificed because they can be more expensive.
The USC study also revealed stark racial disparities: 31% of Black residents and 32% of Latinos experienced food insecurity, compared to 11% of white residents and 14% of Asians.
De la Haye said her team is analyzing data from this year they will publish in December. That analysis will look at investments L.A. County has made in food system over the last two years, including the allocation of $20 million of federal funding to 80 community organizations working on everything from urban farming to food pantries, and the recent creation of the county’s Office of Food Systems to address challenges to food availability and increase the consumption of healthy foods.
“These things that disrupt people’s ability to get food, including and especially cuts to this key program that is so essential to 1.5 million people in the county — we don’t weather those storms very well,” de la Haye said. “People are just living on the precipice.”

How Inventors Find Inspiration in Evolution
Soft batteries and water-walking robots are among the many creations made possible by studying animals and plants.
For centuries, engineers have turned to nature for inspiration. Leonardo da Vinci dreamed of gliding machines that would mimic birds. Today, the close study of animals and plants is leading to inventions such as soft batteries and water-walking robots.
Cassandra Donatelli, a biologist at the University of Washington, Tacoma and an author of a recent review of the burgeoning field of “bioinspiration,” credits the trend to sophisticated new tools as well as a new spirit of collaboration.
“It’s huge,” she said. “We have a biomechanics lab here where we have six or seven engineers and 10 biologists. We’re all physically in the same building, together doing work.”
Despite its promise, the future of bioinspiration is cloudy. The Trump administration has proposed cutting the research budget of the National Science Foundation by 55 percent, directing remaining funds to a few fields such as artificial intelligence and quantum computing. Bioinspiration, which has thrived on this funding, may lose out.
“That work will suffer with N.S.F.’s new priorities,” said Duncan Irschick, a biologist at the University of Massachusetts. “I sincerely worry about handing the mantle of bioinspired research to China.”
Here are some inventions, both new and historical, that have drawn inspiration from nature’s creativity.
In 1941, the Swiss inventor George de Mestral went on a hunting trip. Along the way, burdock burrs stuck to his pants and to the fur of his dog. Curious about their power to cling, de Mestral put the burrs under a microscope. He saw thousands of tiny hooks. The sight led him to imagine a new kind of fastener, one that wouldn’t rely on knots or glue.
A few years later, de Mestral discovered a substance that could make that idea real: nylon. The synthetic fiber could be permanently bent into a hook. De Mestral found that nylon hooks readily attached to fabric and could be peeled away. In 1955, he filed a patent for his invention, which he called Velcro, a combination of the French words “velour” (“velvet”) and “crochet” (“hooks”).
When engineers in Japan created a fleet of high-speed trains in the 1980s and 1990s, they also created some unexpected problems. A train traveling through a tunnel faster than 220 miles an hour compressed the air ahead of it. When the pressure wave reached the tunnel exit, it created a sonic boom.
An engineer named Eiji Nakatsu cast about for a way to make the trains quiet. “The question then occurred to me — is there some living thing that manages sudden changes in air resistance as a part of daily life?” Mr. Nakatsu recalled in a 2005 interview.
Mr. Nakatsu was not just an engineer, but also an avid birder. As he pondered the question, the kingfisher came to mind. When the bird dives at high speed to catch fish, its beak slips into the water without a splash.
So Mr. Nakatsu and his colleagues built train engines with rounded, tapered front ends. Their kingfisher-beak shape reduced the air pressure in tunnels by 30 percent, making the trains quieter and more efficient, even as they traveled more rapidly through tunnels.
In the 1990s, Frank Fish took a close look at the massive knobs that stud the leading edge of humpback whale fins. Dr. Fish, a biologist at West Chester University in Pennsylvania, and his colleagues discovered that these tubercles significantly improve the whales’ performance by keeping water flowing smoothly over their fins, generating extra lift.
Dr. Fish and his colleagues patented their discovery, which has since been adopted by engineers to improve a long list of devices. Tubercles extend the life span of wind turbine blades, for example, and make industrial ceiling fans more efficient. They can even be found on surfboard fins and truck mirrors.
A gecko’s foot is covered by a half-million tiny hairs, each of which splits into hundreds of branches. When a gecko slaps its foot on a wall, many of the branches push tightly against the surface. Each branch creates a weak molecular attraction to the wall, and together they generate a powerful force, yet the gecko can easily pull its foot away in a millisecond.
Dr. Irschick and his colleagues created a fabric that mimics these forces, which they called Geckskin. A piece the size of an index card can hold 700 pounds to a glass surface and be moved without leaving a trace behind.
Pitcher plants are carnivorous, feeding on insects that crawl onto the rim of their pitcher-shaped leaves. The rim is exquisitely slippery, causing prey to lose their footing and fall into a pool of digestive enzymes.
Researchers discovered that when rain and dew collect on the plant, microscopic bumps and ridges pull the water into a film that sticks to the legs of insects. The bugs struggle for traction and end up swimming — and falling.
In 2011, Joanna Aizenberg, an engineer at Harvard, and her colleagues created materials with pitcher-plant patterns on their surface, and these turned out to be slippery as well. A company co-founded by Dr. Aizenberg sells coatings that keep sticky fluids from clogging pipes and paints that repel barnacles from ship hulls.
The mantis shrimp has a pair of odd limbs called dactyl clubs that look a bit like boxing gloves. It uses the clubs to deliver staggering punches with a force equal to that of a .22 caliber bullet — enough to crack open shells. Scientists have long wondered why those impacts don’t crack the dactyl club itself.
Through evolution, the mantis shrimp gained an exoskeleton of astonishing complexity. Its dactyl clubs are composed of layers of fibers; some form herringbone patterns, while others are made of corkscrew-like bundles. These layers deflect the energy from a punch, preventing it from spreading and causing damage.
In May, researchers at the National Institute of Standards and Technology reported the creation of an artificial version of these shock-absorbing layers. When microscopic beads of silica were fired at the material at 1,000 miles an hour, it dented but did not crack. The researchers foresee using the material to make lightweight shields for spacecraft, to protect them from tiny meteoroids.
Ripple bugs are about the size of a grain of rice. They float on the surface of streams by spreading out their legs across the water — but they can also move with astonishing speed, roughly 120 body lengths each second. At a human scale, that would translate to 400 miles an hour.
The secret lies at the end of the middle pair of legs. When a ripple bug dips them into the water, surface tension causes stiff fronds at the ends to fan out in just 10 milliseconds, and the fans become oars. At the end of each stroke, when the insect lifts these oars from the water, the fans snap shut.
In August, Victor Ortega-Jiménez, a biologist at the University of California, Berkeley, and his team announced that, following these principles, it had built tiny robots that walk on water, make rapid turns and brake sharply. And because the water forces the fans open and closed, the Rhagabots — after Rhagovelia, the Latin name for ripple bugs — require little energy from their onboard batteries.
The paralyzing blasts of electricity that an electric eel delivers arise from a sleeve of tissue that wraps around the animal’s body. The tissue contains thousands of layers of cells, which are sandwiched in turn between layers of fluid. The cells pump charged atoms into the fluid, creating a biological battery.
Michael Mayer, a biophysicist at the University of Fribourg in Switzerland, and his colleagues are working to mimic the electric organs in electric eels and other fish. A biologically inspired battery could offer big advantages over conventional ones. They could be safer sources of power for medical implants, for instance, because they would run on organic compounds rather than toxic chemicals.
The team has built contact-lens-shaped prototypes from soft, bendable gels. Dr. Mayer hopes one day to implant the batteries with the same proteins that electric eels use to move charged atoms around.
“Building all this so that it really does the same thing as in the fish is right now beyond our reach,” Dr. Mayer said. “I think this is far in the future, but the project has already gone much further I thought it would.”

Investigation into sickened babies continues after rare California program ID’s botulism
Health officials are warning parents to avoid an infant formula linked to a nationwide botulism outbreak.
As of Nov. 10, 13 babies across 10 states — including one in Los Angeles County — have been sickened by the bacterial spore after consuming ByHeart Whole Nutrition Infant Formula.
The cases were first identified by the California Department of Public Health.
The state operates the Infant Botulism Treatment and Prevention Program, the only manufacturer and provider of an FDA-approved anti-toxin for infant botulism. Officials were tipped off to the outbreak when they noticed an increase in requests for BabyBIG, the anti-toxin, this August, according to Robert Barsanti, a health department spokesman.
The state alerted the U.S. Centers for Disease Control and Prevention and sparked a nationwide investigation, which is ongoing.
Health officials are asking major retail stores such as Amazon, Target, Walmart and Whole Foods to remove the product from their shelves. They are also asking parents and caregivers to check their infant formula and throw away any cans manufactured by ByHeart Inc.
If a parent or caregiver thinks they may have a child with botulism who has ingested baby formula, take photos of the can and lot number, said Jemma Alarcon, medical director of the Los Angeles County health department’s Food and Water Safety unit.
“We’re recommending they either return it to where they got it, so they can get a reimbursement, or they can just throw it away,” she said. “It is very important that if you do see symptoms, like sleepiness, lethargy, constipation, or the baby is not acting like itself, just go to the emergency room, go to your primary care doctor and let them know that the baby was consuming this formula.”
In a press release, county health officials also mentioned symptoms such as difficulty feeding, sucking or swallowing; weak cry or diminished facial expression; poor head control; and muscle weakness or trouble breathing.
On Saturday, ByHeart voluntarily recalled two lots of the contaminated infant formula: Lot 206VABP/251261P2 (Use by 01 Dec 2026) and Lot 206VABP/251131P2 (Use by 01 Dec 2026).
There have been no deaths associated with the outbreak.
According to the FDA, the product accounts for less than 1% of all U.S. infant formula sales.
Nine of the 13 cases in the outbreak so far have been confirmed; four are pending. All are associated with the same formula and the same strain of bacteria.
The company said in a statement on its website that it has voluntarily recalled the lots, but noted that the powdered formula tested by the California Department of Public Health came from a can that had previously been opened.
“We know that Clostridium botulinum is a bacteria that exists naturally in the environment — in places like soil, dust, and even vegetables — meaning that an opened can can be contaminated in multiple ways,” the company said on its website.
It also noted that “global regulatory and scientific authorities do not recommend testing powder infant formula for Clostridium botulinum, and no U.S. or global infant formula company tests for Clostridium botulinum.”
Spores produced by the botulism bacteria are heat-resistant and exist widely in the environment. In the absence of oxygen they germinate, grow and then excrete toxins.
Although the disease is rare, it is associated with improperly processed food that allows the bacteria spores to survive and grow. If left untreated, the toxin can lead to respiratory failure and death..
The disease is acquired differently in infants than in adults. For an adult to get the disease, they must ingest the toxin. Infants, on the other hand, can get sick just from ingesting the bacterium because it will develop into the toxin in their gut, due to their immature immune systems.
Bill Marler, an attorney with Marler Clark, a food safety law firm, said infant botulism cases are exceedingly rare. He said he has a client in Arizona whose infant was hospitalized for two weeks and placed on a feeding tube for four weeks after ingesting allegedly contaminated ByHeart formula.
He said botulism spores are associated with deficiencies in cleanliness on food manufacturing lines. Once they are established in a food source, however, they are hard to get rid of.
“Botulism spores are pretty tough to kill, even with the hot water that you would add to infant formula,” he said. “Those spores are hardy little guys. It could have come in on, you know, somebody shoes or pallet, or, you know, anything like that.”
