California plans to enlist AI to translate healthcare information

Tener gripe, tener gripa, engriparse, agriparse, estar agripado, estar griposo, agarrar la gripe, coger la influenza. In Spanish, there are at least a dozen ways to say someone has the flu — depending on the country.

Translating “cardiac arrest” into Spanish is also tricky because “arresto” means getting detained by the police. Likewise, “intoxicado” means you have food poisoning, not that you’re drunk.

The examples of how translation could go awry in any language are endless: Words take on new meanings, idioms come and go, and communities adopt slang and dialects for everyday life.

Human translators work hard to keep up with the changes, but California plans to soon entrust that responsibility to technology.

State health policy officials want to harness emerging artificial intelligence technology to translate a broad swath of documents and websites related to “health and social services information, programs, benefits and services,” according to state records. Sami Gallegos, a spokesperson for California’s Health and Human Services Agency, declined to elaborate on which documents and languages would be involved, saying that information is confidential.

The agency is seeking bids for the ambitious initiative, though its timing and cost is not yet clear. Human editors supervising the project will oversee and edit the translations, Gallegos said.

Agency officials said they hope to save money and make critical healthcare forms, applications, websites, and other information available to more people in what they call the nation’s most linguistically diverse state.

The project will start by translating written material. Agency Secretary Mark Ghaly said the technology, if successful, may be applied more broadly.

“How can we potentially not just transform all of our documents, but our websites, our ability to interact, even some of our call center inputs, around AI?” Ghaly asked during an April briefing on AI in healthcare in Sacramento.

But some translators and scholars fear the technology lacks the nuance of human interaction and isn’t ready for the challenge. Turning this sensitive work over to machines could create errors in wording and understanding, they say — ultimately making information less accurate and less accessible to patients.

“AI cannot replace human compassion, empathy, and transparency, meaningful gestures and tones,” said Rithy Lim, a Fresno-based medical and legal interpreter for 30 years who specializes in Cambodian and Khmer languages.

Artificial intelligence is the science of designing computers that emulate human thinking. A type of artificial intelligence known as generative AI, or GenAI, in which computers are trained using massive amounts of data to “learn” the meaning of things and respond to prompts, is driving a wave of investment, led by such companies as Open AI and Google.

AI is quickly being integrated into healthcare, including programs that diagnose diabetic retinopathy, analyze mammograms and connect patients with nurses remotely. Promotors of the technology often make the grandiose claim that soon everyone will have their own “AI doctor.”

AI also has been a game changer in translation. ChatGPT, Google’s Neural Machine Translation and Open Source are not only faster than older technologies such as Google Translate, but they can process huge volumes of content and draw upon a vast database of words to nearly mimic human translation.

Whereas a professional human translator might need three hours to translate a 1,600-word document, AI can do it in a minute.

Arjun “Raj” Manrai, an assistant professor of biomedical informatics at Harvard Medical School and the deputy editor of New England Journal of Medicine AI, said the use of AI technology represents a natural progression in medical translation, given that patients already use Google Translate and AI platforms to translate for themselves and their loved ones.

“Patients are not waiting,” he said.

He said generative AI could be particularly useful in this context.

These translations “can deliver real value to patients by simplifying complex medical information and making it more accessible,” he said.

In its bidding documents, the state says the goal of the project is to increase “speed, efficiency, and consistency of translations, and generate improvements in language access” in a state where 1 in 3 people speak a language other than English, and more than 200 languages are spoken.

In May 2023, the state Health and Human Services Agency adopted a “language access policy” that requires its departments to translate all “vital” documents into at least the top five languages spoken by Californians with limited English proficiency. At the time, those languages were Spanish, Chinese, Tagalog, Vietnamese, and Korean.

Examples of vital documents include application forms for state programs, notices about eligibility for benefits, and public website content.

Currently, human translators produce these translations. With AI, more documents could be translated into more languages.

A survey conducted by the California Health Care Foundation late last year found that 30% of Spanish speakers have difficulty explaining their health issues and concerns to a doctor, compared with 16% of English speakers.

Health equity advocates say AI will help close that gap.

“This technology is a very powerful tool in the area of language access,” said Sandra R. Hernández, president and CEO of the foundation. “In good hands, it has many opportunities to expand the translation capability to address inequities.”

But Hernández cautioned that AI translations must have human oversight to truly capture meaning.

“The human interface is very important to make sure you get the accuracy and the cultural nuances reflected,” she said.

Lim recalled an instance in which a patient’s daughter read preoperative instructions to her mother the night before surgery. Instead of translating the instructions as “you cannot eat” after a certain hour, she told her mom, “You should not eat.”

The mother ate breakfast, and the surgery had to be rescheduled.

“Even a few words that change meaning could have a drastic impact on the way people consume the information,” said Sejin Paik, a doctoral candidate in digital journalism, human-computer interaction and emerging media at Boston University.

Paik, who grew up speaking Korean, also pointed out that AI models are often trained from a Western point of view. The data that drive the translations filters languages through an English perspective, “which could result in misinterpretations of the other language,” she said. Amid this fast-changing landscape, “we need more diverse voices involved, more people thinking about the ethical concepts, how we best forecast the impact of this technology.”

Manrai pointed to other flaws in this nascent technology that must be addressed. For instance, AI sometimes invents sentences or phrases that are not in the original text, potentially creating false information — a phenomenon AI scientists call “hallucination” or “confabulation.”

Ching Wong, executive director of the Vietnamese Community Health Promotion Project at UC San Francisco, has been translating health content from English into Vietnamese and Chinese for 30 years.

He provided examples of nuances in language that might confuse AI translation programs. Breast cancer, for instance, is called “chest cancer” in Chinese, he said.

And “you” has different meanings in Vietnamese, depending on a person’s ranking in the family and community. If a doctor uses “you” incorrectly with a patient, it could be offensive, Wong said.

But Ghaly emphasized that the opportunities outweigh the drawbacks. He said the state should “cultivate innovation” to help vulnerable populations gain greater access to care and resources.

And he was clear: “We will not replace humans.”

5 Great Stargazing Trains

5 Great Stargazing Trains

Stargazing, it turns out, doesn’t have to be a stationary activity.

On railway lines around the world, from the Arctic Circle to New Zealand, a select set of evening train excursions take riders deep into dark-sky territory — some en route to remote station stops decked out with telescopes, others featuring onboard astronomers.

These five rail journeys (all of which are accessible) range from two- to three-hour desert outings to a hunt for the northern lights. One route even has a planetarium on rails. All promise a renewed appreciation of train travel — and of our pale blue dot’s improbable place in the cosmos.

Nevada

Any stargazing train worth its salt requires one thing: a dark sky. The Star Train resoundingly checks that box, traveling through a part of eastern Nevada that is one of the least-populated places in the lower 48.

Run by the Nevada Northern Railway in partnership with nearby Great Basin National Park, the train departs the historic East Ely Depot, in Ely, Nev., early enough in the evening to catch the sunset over the Steptoe Valley, and then cruises through darkening skies to its destination: a remote corner of the desert appropriately called Star Flat, where a stargazing platform outfitted with telescopes awaits. There, riders disembark (equipped with red-light necklaces to help preserve their night vision) and take turns viewing the cosmos, guided by professional astronomers. (Last year’s onboard stargazing guides came from Caltech; in previous seasons, the National Park Service’s Dark Rangers, who specialize in night-sky activities, accompanied trips.)

The Star Train makes its two-and-a-half-hour round-trip journey most Friday evenings between mid-May and mid-September, and tickets ($65 for adults) can sell out almost a year in advance — though members of the Nevada Northern Railway Museum get early access. Alternatively, the railroad’s more frequent Sunset, Stars and Champagne excursions trade telescopes for desert sundowners but feature the same expert stargazers and the same Nevada night sky, which is often dark enough to see the Milky Way with the naked eye.

New Mexico

While plenty of heritage railroads across the United States offer twilight rides and nighttime excursions, at the moment there’s only one other dedicated, regularly scheduled stargazing train in North America besides the Star Train: the Stargazer, operated by Sky Railway, in Santa Fe, N.M.

Much like its Nevada counterpart, the Stargazer makes a two-and-a-half-hour round trip through dark-sky country, though in this case, the journey really is the destination, because it doesn’t make any stops. More of a rolling night-sky revue, the Stargazer features live music and professional astronomers who share their celestial knowledge and stories as the train rumbles into the vast Galisteo Basin south of Santa Fe. Sky Railway’s colorfully painted trains feature heated, enclosed passenger cars to stave off the evening chill and flatbed cars open to the night sky.

Departing from the Santa Fe Depot downtown, the train normally runs once a month (adult tickets from $139, including a champagne welcome toast). Sky Railway also occasionally schedules excursions for special celestial events.

New Zealand

With its alpine landscapes and rugged coastline, New Zealand’s South Island is practically tailor-made for scenic daytime train journeys. But when night falls, the sparsely populated island — home to the Southern Hemisphere’s largest International Dark Sky Reserve — is heaven for stargazers, too.

This year, Great Journeys New Zealand, which operates the country’s tourist-centric long-distance trains, is offering a special nighttime run of the Coastal Pacific, whose route skirts the South Island’s northeastern coast. Timed to Matariki, the Maori new year, which is heralded by the first rising of the Pleiades star cluster, the eight-hour round trip from Christchurch is a cultural and astronomical celebration.

After the first half of a four-course onboard dinner, the train arrives in Kaikoura, in dark-sky country, for a guided stargazing stop with a range of telescopes — and fire pits and a night market. (The rain plan involves a virtual stargazing session at the local museum using virtual reality headsets.) Dinner resumes back on the train as it returns to Christchurch. This is a strictly limited engagement, on the rails for one night only: July 11, for 499 New Zealand dollars, about $295, per person.

In the far northern reaches of Norway, inside the Arctic Circle, you can ride a train that chases another wonder of the night sky: the aurora borealis. Twice a week from October to March, the Northern Lights Train takes its riders into the dark polar night in pursuit of the aurora’s celestial light show.

From the remote town of Narvik, the train travels along the Ofoten Railway, the northernmost passenger rail line in Western Europe. The destination on this three-hour round-trip excursion (1,495 kroner, or about $160) is Katterat, a mountain village accessible only by rail and free of light pollution, making it an ideal place to spot the aurora. At the Katterat station, local guides and a campfire cookout await, as does a lavvu, the traditional tent used by the Sami people of northern Scandinavia, offering a respite from the cold (as well as hot drinks and an open fire for roasting sausages).

And aboard the train, the lights stay off, which means that on a clear night, you might even catch the northern lights on the way there and back.

Leave it to Japan to take the stargazing train to another level.

The High Rail 1375 train — so named because it runs along Japan’s highest-elevation railway line (the high point is 1,375 meters, or roughly 4,500 feet, above sea level) — is one of JR East’s deliberately unhurried Joyful Trains, which the railway company describes as “not only a means of transportation, but also a package of various pleasures.” This astronomy-themed train certainly packs plenty of joy into its two cars, with seat upholstery inspired by constellations, a snack bar, a souvenir shop and a planetarium car with a library of astronomy books and images of the night sky projected onto its domed ceiling.

Advertisement

The train makes two daytime runs along the mountainous Koumi Line, taking a little over two hours to travel between Kobuchizawa (accessible by express train from Tokyo) and Komoro. But the main event is the High Rail Hoshizora (“Starry Sky”) evening trip, which includes an extended stop at Nobeyama Station (the highest in the country) for a guided stargazing session. A one-way ride on High Rail 1375, which runs on weekends and occasional weekdays, requires a seat reservation if you’re traveling on a Japan Rail pass, or a stand-alone ticket plus seat reservation (2,440 yen, or about $15). And remember to preorder a special “Starry Sky” bento box.

A Physicist Who Thinks in Poetry from the Cosmic Edge

A Physicist Who Thinks in Poetry from the Cosmic Edge

Much of the praise for Chanda Prescod-Weinstein’s debut book in 2021, “The Disordered Cosmos: A Journey Into Dark Matter, Spacetime, and Dreams Deferred,” lauded the way she used personal experiences in physics to discuss the social and political inequities that exist alongside scientific breakthroughs.

“It contains the narrative of dreams deferred,” Dr. Prescod-Weinstein, a physicist at the University of New Hampshire, explained in April at a bookstore in Chicago. But its very existence, she said, also “represented a dream deferred, because that was not the dream of what my first book was going to be.”

Her second book reclaims that dream. Released on April 7, “The Edge of Space-Time: Particles, Poetry, and the Cosmic Dream Boogie” is less pain and more play, a homage to the big questions that made Dr. Prescod-Weinstein want to become a physicist in the first place. She begins the book by asserting that it is humanity’s duty to uncover and share the story of our universe. Her latest offering toward that duty is a journey through physics that is tightly bound to her own cultural roots.

In the midst of a multicity book tour, Dr. Prescod-Weinstein spoke with The New York Times about guiding readers through the cosmos from her own point of view and about some of the art, poetry and literature she drew on to shape that journey. This conversation has been edited for brevity and clarity.

Why include so many references to poetry in a book about physics?

Advertisement

I knew poetry before I knew physics. It was part of my upbringing. I loved A.A. Milne’s “Now We Are Six” and Edward Lear’s “Nonsense Limericks.” Both of my books draw their subtitles from Langston Hughes’s “Montage of a Dream Deferred.”

Adrienne Rich’s poem “The Burning of Paper Instead of Children” became a guiding light for how my work would move in the world. It also opened up for me that I need language. That’s true among physicists. Even an equation is a sentence; even an equation is telling a story.

As physicists, we’re always working in language to connect what we learn with what we know. Poetry is one of the first places that my brain goes to draw those links. Language, as it moves in my brain, is often in Hughes and Rich and Shakespeare. Those are the lines that flicker up for me.

What if we got away from the argument that doing cosmology and particle physics is practical or materially valuable? Then we have to accept that we’re like the poets. What we do is important culturally in the same way poetry is. A piece of this book is me saying there is value in banding with the poets, and fighting for the value of being curious and trying to articulate the world with whatever tools are available to us. Not for the purposes of selling something, but for the purpose of fulfilling our humanity.

Another theme throughout the book is the story of Lewis Carroll’s Alice and her adventures in Wonderland.

Advertisement

Being a science adviser on future installments in The Legendborn Cycle, a fantasy series written by Tracy Deonn, is one reason Alice is in my book. It has allowed me to be open to the playful side that physics, as a Black queer person, can take from you. I wanted the book to be whimsical, because that’s who I was when I first arrived in physics, and that’s who I want to be when I die.

Part of the call of quantum physics is to change what our sense and sensibility are. When you look at the world through this framework — like the idea that particles have spin but don’t really spin — it sounds like nonsense. Except that’s literally how the universe works. Physics is our “through the looking glass.” It’s real.

Your first chapter invites readers to reflect on the metaphors used to describe the universe, like the “fabric” of space-time or electromagnetic “fields.” Why open in this way?

A lot of books about quantum physics start with its history. I wanted as much as possible not to just do that. I had actually planned to start it with the Stern-Gerlach experiment of 1922. But then I read an essay by the poet Natasha Trethewey about abiding metaphors and started to ask myself what the abiding metaphors of my physics training were.

We don’t ever take time in our classes to ask, “What do we mean when we say ‘space’? What do we mean when we say ‘space-time’?” There are these metaphysical questions that I often told myself were for the philosophers. This book was me letting myself think of them as physics.

Advertisement

One metaphor you invoke is the “edge” — not only the edge of the universe and of scientists’ understanding, but also existing at the edge of certain identities.

In “Disordered Cosmos,” I talked a lot about being at the margin and looking toward the center. With “The Edge of Space-Time,” I’m choosing to make the margin the center of the story. Part of that was me fully embracing what makes me the physicist I am. I’m an L.A. Dodgers fan. I love “Alice in Wonderland.” I love “Star Trek.” There’s lots of all of that in the book.

Picking a metaphor is a culturally situated decision. I wrote a line that says black holes are the best laid edges in the universe. I did, at some point, think that only some people were going to get this. But for people who don’t understand the reference to Black hairstyles, the sentence is still legible. And for those who do, it will feel like we just had an in-group moment. Anyone who thinks about laying their edges deserves to have an in-group moment in a physics book. Because we are physics, too.

Black students are often told that if you want to be a physicist, then you will make yourself as close to such-and-such mold as possible. At a young age, we have this understanding that whiteness and science are associated with each other, but we are also witnessing in ourselves that this can’t be entirely correct. There’s this narration of, “Well, sure, you can be Black in physics, but that means you have to acclimate to the ‘in physics’ part, and never that physics has to acclimate to the Black part.”

I use the example of rapper Big K.R.I.T.’s song “My Sub Pt. 3 (Big Bang),” in which someone tries to wire up subwoofers in his car but fries the wires because he doesn’t ground them properly. I don’t know if Big K.R.I.T. would think of this as a science story, but I think we should learn to read it as one. Not to contain it in science, but to say it overlaps there. This can be a rap song. It can be about the cultural significance of subwoofers and the Big Bang as a metaphor for the beat. And it can also be about cosmology and about how everybody who wires up cars or does this kind of work is a scientist, too.

How do you want readers to approach this book?

There is this feeling that you’re supposed to read a book like this and walk away an expert. That’s actually not the point of this book at all. The point is to wander through physics. Even if math terrifies you, you are entitled to spend some time with it.

And so here, I have made you a book with a bunch of tidbits on the oddities of the universe. The universe is stranger and more queer and more wonderful and more full of possibility than whatever limitations you might be experiencing right now. Physics challenges what we are told are social norms. For example, non-trinary neutrinos are fundamental to our standard model of physics.

“Non-trinary,” as in they shift between three different forms.

Non-trinary is natural. It’s such a challenge to the current anti-trans rhetoric that says people can only ever be one thing.

Advertisement

I don’t need my book to be the most important thing that someone reads. But I want it to be a source of hope. If it reminds you that, as my mom says, the universe is bigger than the bad things that are happening to us, then that’s all you need to remember. I’m good with that.

Footage shows Central Valley dairy workers kicking young calves, pulling them with pliers

In late February, animal rights activists flew a drone over a calf ranch in the Central Valley and watched as workers kicked and punched the animals.

For the record:

7:15 p.m. May 12, 2026This article has been updated to reflect that no calves from Agresti Calf Ranch have ever gone on to be used for Clover Sonoma milk supplies, and the calf ranch opened only in 2025. In additional comments, Clover Sonoma also said in the future, no animals from Agresti Calf Ranch will be part of its supply.

Footage reviewed by The Times shows a worker pulling a calf by the nose with pliers.

It shows two workers removing the budding horns of a calf with a hot iron. While one held the frightened animal’s head, the other — wearing a sweatshirt with an image of the Virgin Mary — applied the iron to a horn. After a puff of smoke, the calf fell to its side, appearing motionless.

Both male and female calves produce horns. To prevent injury to the animals and their handlers, these are commonly removed. Humane guidelines require anesthesia.

The footage was collected by the group Direct Action Everywhere, known for tactics including releasing beagles from medical breeding facilities and abused calves from farms. It was shot at the Agresti Calf Ranch in Ceres, near Modesto, which is certified by the American Humane Society for its ethical treatment of animals. The workers could not be reached for comment. One was subsequently terminated, the Humane Society said.

Advertisement

The Agresti Calf Ranch opened in 2025 and is operated by the owners of Double D Dairy, just up the road. Double D Dairy owns more than 10,000 cows across several operations.

The owner of Double D, Dominic Assali, declined to answer questions in person. A phone number for the dairy online is disconnected. In response to an email to his personal account, Assali said, “Animal welfare and safety are incredibly important to us, and we have a zero-tolerance policy for any mistreatment.

“We’ll always take immediate, thorough action to address any operational issues, as we have in this instance,” the email said.

The American Humane Society is a 150-year-old nonprofit focused on animal welfare. Among other things, it certifies animal safety on farms as well as on movie sets. In a statement, it said only 10% of animals raised on farms in the U.S. are certified as humanely treated.

Assali is the grandson of the farm’s founders, Harold and Marlene Agresti. He is a board member of Western United Dairies, the largest dairy trade group in California.

The mistreatment captured on video has also created a headache for a prominent California sustainable milk brand, Clover Sonoma, based in Sonoma County.

It gets 10% to 15% of its milk from Double D, and Assali and his family are featured on Clover Sonoma’s website. No calves from Agresti Calf Ranch have ever gone on to be used in Clover Sonoma milk supplies, the company said in a statement. It’s unclear whether the abused calves were being raised for beef or dairy.

A Clover Sonoma sign hung outside the main dairy complex on a recent visit.

Clover Sonoma markets its milk, yogurt and cheese products as humanely sourced and environmentally sound. It was the first dairy company to receive a cruelty-free certification from the American Humane Society in 2000. The website also features a “Our Promise” page, which states the company demands “the humane treatment of animals.”

“We were deeply concerned by the reported mistreatment of some cows captured on video at Agresti Calf Ranch during a separate cow operation,” the company said in an email.

“The rough handling shown at Agresti Calf Ranch is contrary and inconsistent with the humane practices we have fostered for decades and which we demand of all our suppliers.”

Clover Sonoma said it suspended business with Double D as soon as it became aware of the incidents and began “a rigorous audit,” which just ended.

“Clover and the American Humane Society have concluded that the mistreatment was an isolated issue, not systemic or reflective of Agresti Calf Ranch’s personnel. Corrections have been made, including the termination of the employee in the video. As such, we are comfortable reinstating the milk from Double D Dairy.”

After this story published, Clover went further and said a condition of Double D’s reinstatement will be that no animals from Agresti Calf Ranch will be part of Clover’s dairy supply.

A statement from the Humane Society said Clover Sonoma is working with Double D to strengthen its whistleblower policy and training, and has “reiterated its commitment to ongoing independent, third-party audits,” with both announced and unannounced visits.

Clover Sonoma mainly buys and processes milk from dairies in verdant Sonoma County, as the company’s marketing suggests. Double D Dairy is one of its few suppliers in the Central Valley, which is associated more with industrial-scale agriculture.

On a recent weekday, the calf ranch and dairy farm were visible from a public road. Holstein calves, a popular dairy breed, could be seen in cages through small trees in front of the enclosures. The sound of mooing and a pressure washer could be heard. The smell of manure and dirt wafted in the humid air.

Most dairy companies remove calves from their mothers after birth, raising them separately so they don’t take the mother’s commercially valuable milk. Some dairy farms send calves out to third-party calf ranches for rearing. Others raise them on-site. Female calves are typically raised to become milk cows. Male calves are sent away to become beef or other meat-based products, such as pet food.

A 2025 State Water Board document shows the farm houses an average of 700 calves at any one time, with a maximum 1,400.

The Direct Action Everywhere activists were recently on a public road near Double D’s main farm, flying a drone over the property. Within 30 minutes of their arrival, seven Stanislaus County sheriff’s vehicles arrived and surrounded the activists.

A heavily armed officer asked to see the drone pilot’s Federal Aviation Administration license, which he provided. After confirming it was valid, a sheriff’s deputy — one of nine at the scene — told the activists they could remain on the road but could not trespass.

Asked about the heavy response, a deputy said there had been several recent violent incidents from animal rights groups at the site, and mentioned the groups had sent in “busloads” of activists.

The Times reached out to the Sheriff’s Office to get more details about those events but did not get a response.

Temple Grandin, author and professor of livestock medicine at Colorado State University, said that punching and kicking livestock is considered abusive.

An expert in livestock welfare, she said that handlers can tap, push and nudge animals. But if the level of force goes beyond what could bend the side of a cardboard box, “it’s abuse. Period.”

She said the calves’ reaction to the hot iron indicates that pain medication, such as lidocaine, was not applied before the procedure. Double D did not respond to a question about whether medication was given before the procedure.
