Commentary: She was wrongly snagged by Trump's word police. Now her medical research is down the drain
SAN FRANCISCO — Nisha Acharya, an eye doctor and UC San Francisco professor, was at her campus clinic tending patients when a surprising email arrived.
Her federal research grant had just been terminated, according to a reporter for the Washington Post, who wondered if Acharya had any comment.
She was stunned. Her research, into the workings of the shingles vaccine, didn’t seem remotely controversial. The $3-million grant was the second she’d received, after years of similar work. The National Institutes of Health, which awarded the grant and regularly reviewed Acharya’s performance, had been pleased with all she’d accomplished.
Nevertheless, the NIH tersely informed the university its latest grant was among dozens terminated because the federal government, under President Trump, would no longer support research focused on “why individuals are hesitant to be vaccinated and/or explore ways to improve vaccine interest and commitment.”
Acharya’s research had nothing to do with any of that.
But the mention of “hesitancy” and “uptake” in her grant application — referring to the concern some cornea specialists had about the vaccine for those with shingles in the eye — was apparently all it took to snare Acharya in a dragnet mounted by the Trump administration word police.
Acharya fears the Trump administration’s heedless termination of grants will set back scientific and medical research for years to come.

Perhaps “hesitancy” and “uptake” generated an AI response, or triggered some on-the-hunt algorithm. Acharya can’t be entirely sure, but there’s no evidence an actual human being, much less any sort of expert on vaccines or shingles, reviewed her grant proposal or assessed her work.
She’s gotten no explanation beyond that one, formulaic March 10 email dispatched to the university. “I lost funding immediately,” Acharya said.
Views of the 47th president, from the ground up
The randomness of the administration’s action, and its apparent error, is maddening enough. But it’s also frightening, Acharya said, to think that political considerations are now guiding science and scientific research, erasing years of effort and thwarting potential cures and the chance at future breakthrough treatments.
“I don’t think government is in a position, or should be, to dictate what’s important in science,” Acharya said over lunch on UCSF’s sparkling Mission Bay campus.
Trump’s heedless, meddlesome policy, she suggested, is going to scare off a whole generation of would-be scientists and medical researchers, undermining the quest for knowledge, hurting the public and negatively affecting people’s health “for years to come.”

Acharya was in a high school when she reached a fork in the road. Now 50, she pressed her hands into a “V” shape to illustrate the two paths.
Acharya’s grant was worth $3 million spread over five years of research. She was in the second year of the grant when it was abruptly canceled.

At the time she was a violinist in the Chicago Youth Symphony, touring the world with the orchestra. She also loved science. Her father was a pharmaceutical chemist. Her mother taught high school math and chemistry.
She realized, Acharya said, she wasn’t ready to make the commitment or accept the all-encompassing sacrifice needed to forge a professional career in music. So science became her chosen route.
At Stanford, she majored in biology and received a master’s degree in health services research. From there, it was on to UCSF medical school. “I love scientific knowledge. But I really wanted to be able to directly interact with patients,” said Acharya, a self-described people person.
A favorite professor, who specialized in eye infection and inflammation, steered her into ophthalmology and helped Acharya find her life’s passion. She smiled broadly as she rhapsodized with mile-a-minute enthusiasm about her work, eyes wide and fingers fluttering over the table, as though she was once again summoning Bach or Paganini.
“The body affects everything in the eye,” she explained. “Like, if you have an infection, you can get it in the eye. If you have an autoimmune disease, you can have manifestations in the eye. You have blood pressure problems, you can see it in the eye. The eye is like, really, a window into the body.”
Acharya latest research was focused on how the shingles vaccine works.
Shingles is a rash brought on by the varicella zoster virus, which also causes chickenpox. Once chickenpox subsides, the virus can remain dormant in a person’s body for decades before erupting again.
“In the first grant, we showed that the vaccine is very effective at preventing shingles and shingles in the eye if you’ve never had it,” Acharya said. “But we hadn’t gotten to the question of what if you already have shingles in the eye?”
It was work, Acharya said, that no one else was doing, aimed at preventing a loss of vision or blindness. It was not, she repeatedly emphasized, an attempt to promote vaccination, a once-common practice now tangled in layers of political, social and cultural debate — or, for that matter, to dissuade anyone from getting vaccinated.
“This is the kind of research that you would think the government would want. Safety and effectiveness … the pros and the cons,” Acharya said, giving a small, puzzled shake of her head. “I wanted to just get the information out there so people can use it.”
Now that guidance won’t be available anytime soon.
If ever.

Acharya has never been politically active. Her whole life and career, she said, have been devoted to the furtherance of science.
While she leans left, she’s never been wedded to any party or ideology; Acharya has found reasons to agree — and disagree — with Democrats and Republicans alike.
She didn’t vote for Trump, but didn’t see her support for Kamala Harris as making any sort of stand for scientific inquiry, or as a means of protecting her grant. “It never crossed my mind,” she said.

The five-year grant paid 35% of Acharya’s salary — she was nearing the end of Year Two — and, while the loss of income isn’t great, she’ll manage. “I’m a professor and I’m a doctor as well,” she said. “I’m not going to lose my job.”
Acharya has been forced, however, to lay off two data analysts, and a third research position is in jeopardy. Her voice thickened as she discussed those let go. At one point, she seemed to be fighting back tears.
“I’ve cried with my team a lot,” she said over the soft thrum of conversation in the airy cafeteria-style bistro. “I’m just keeping it together because I have to … I still take care of patients. I still teach. I can’t lose it like that. I feel like … I have to find some way to keep on going.”
In its zeal to dismantle the federal government — driven more, it seems, by political calculation and a taste for vengeance than any well-thought-out design — the Trump administration has terminated hundreds of grants, ending research focused on Alzheimer’s disease, cancer, HIV/AIDS, heart disease, COVID-19, mental health services and addiction, among other areas of scientific pursuit.
Hundreds of millions of dollars that already have been spent are now wasted. The fruits of all that research have been blithely and abruptly lopped off the vine.
It’s impossible, Acharya said, to calculate the loss. It’s painful to even try. “All the things that might not be learned,” she mused wistfully. “All the potential gains out there” that may go unrealized.
The termination notice UCSF received from the National Institutes of Health gave Acharya 30 days to appeal if she believed the decision to end her research was made in error. She did so.
A few days later, the university received a pro forma email acknowledging receipt of Acharya’s appeal.
Since then, nothing.

Lyrids Meteor Shower: How to Watch, Peak Time and Weather Forecast
Our universe might be chock-full of cosmic wonder, but you can observe only a fraction of astronomical phenomena with the naked eye. Meteor showers, natural fireworks that streak brightly across the night sky, are one of them.
The latest observable meteor shower will be the Lyrids, which has been active since April 14 and is forecast to continue through April 30. The shower reaches its peak April 21 to 22, or Tuesday night into Wednesday morning.
According to NASA, the Lyrids are one of the oldest known meteor showers, and have been enjoyed by stargazers for nearly 3,000 years. Their bright, speedy streaks are caused by the dusty debris from a comet named Thatcher. They appear to spring from the constellation Lyra, which right now can be seen in the eastern sky at night in the Northern Hemisphere.
The moon will be about 27 percent full tonight, appearing as a thick crescent in the sky, according to the American Meteor Society.
To get a hint at when to best watch for the Lyrids, you can use this tool, which relies on data from the Global Meteor Network. It shows fireball activity levels in real time.
And while you gaze at the heavens, keep an eye out for other stray meteors streaking across the night sky. Skywatchers are reporting that the amount of fireballs is double what is usually seen by this point in the year.
Where meteor showers come from
There is a chance you might see a meteor on any given night, but you are most likely to catch one during a shower. Meteor showers are caused by Earth passing through the rubble trailing a comet or asteroid as it swings around the sun. This debris, which can be as small as a grain of sand, leaves behind a glowing stream of light as it burns up in Earth’s atmosphere.
Meteor showers occur around the same time every year and can last for days or weeks. But there is only a small window when each shower is at its peak, which happens when Earth reaches the densest part of the cosmic debris. The peak is the best time to look for a shower. From our point of view on Earth, the meteors will appear to come from the same point in the sky.
The Perseid meteor shower, for example, peaks in mid-August from the constellation Perseus. The Geminids, which occur every December, radiate from the constellation Gemini.
How to watch a meteor shower
Michelle Nichols, the director of public observing at the Adler Planetarium in Chicago, recommends forgoing the use of telescopes or binoculars while watching a meteor shower.
“You just need your eyes and, ideally, a dark sky,” she said.
That’s because meteors can shoot across large swaths of the sky, so observing equipment can limit your field of view.
Some showers are strong enough to produce up to 100 streaks an hour, according to the American Meteor Society, though you probably won’t see that many.
“Almost everybody is under a light-polluted sky,” Ms. Nichols said. “You may think you’re under a dark sky, but in reality, even in a small town, you can have bright lights nearby.”
Planetariums, local astronomy clubs or even maps like this one can help you figure out where to go to escape excessive light. The best conditions for catching a meteor shower are a clear sky with no moon or cloud cover, sometime between midnight and sunrise. (Moonlight affects visibility in the same way as light pollution, washing out fainter sources of light in the sky.) Make sure to give your eyes at least 30 minutes to adjust to seeing in the dark.
Ms. Nichols also recommends wearing layers, even during the summer. “You’re going to be sitting there for quite a while, watching,” she said. “It’s going to get chilly, even in August.”
Bring a cup of cocoa or tea for even more warmth. Then lie back, scan the sky and enjoy the show.
Where weather is least likely to affect your view
Storm systems sweep across the country in early spring, and some will be obscuring skies tonight. But there will still be plenty of areas with clear skies, particularly in parts of the central United States.
“The best spot is going to be in the Upper Midwest,” said Rich Bann, a meteorologist with the Weather Prediction Center.
Minnesota, Wisconsin and Iowa will offer especially good sky-viewing weather and a beach on the Great Lakes could be a nice spot to look up at the stars.
But don’t expect to view the show from Chicago, as Illinois could see some thunderstorms. The weather will be better in the Northern and Central Plains, particularly the eastern Dakotas.
High, wispy clouds are expected over the Ohio and Tennessee Valleys and into parts of the Mid-Atlantic. But, Mr. Bann said, “you may be able to see some shooting stars through thin clouds.”
Clouds will be draped across much of the Southeast and the Northeast, though there could be some clearing in Florida, Georgia, the Carolinas and Virginia. Remember, the meteors could be visible all night long. If you look outside and see clouds, try again later.
Catching the spectacle will be challenging across much of the West, particularly from Washington into Northern California, where a storm system is bringing rain and snow. That system will move east overnight.
There are likely to be some pockets of clear skies at times across southern Nevada, northwest Arizona and southwest Utah, Mr. Bann said.

FBI probes cases of missing or dead scientists, including four from the L.A. area
WASHINGTON — Amid growing national security concerns, the FBI said Tuesday that it has launched a broad investigation in the deaths or disappearances of at least 10 scientists and staff connected to highly sensitive research, including four from the Los Angeles area.
“The FBI is spearheading the effort to look for connections into the missing and deceased scientists. We are working with the Department of Energy, Department of War, and with our state and state and local law enforcement partners to find answers,” the agency said in a statement.
The FBI’s announcement comes after the House Oversight Committee announced that it would investigate reports of the disappearance and deaths of the scientists, sending letters seeking information from the agencies involved in the federal inquiry as well as NASA, which owns the Jet Propulsion Laboratory in La Cañada Flintridge, where three of the missing or dead scientists worked.
“If the reports are accurate, these deaths and disappearances may represent a grave threat to U.S. national security and to U.S. personnel with access to scientific secrets,” Reps. James Comer (R-Ky.), chairman of the committee, and Eric Burlison (R-Mo.) wrote in the letters.
President Trump told reporters last week that he had been briefed on the missing and dead scientists, which he described as “pretty serious stuff.” He said at the time that he expected answers on whether the deaths were connected “in the next week and a half.”
Michael David Hicks, who studied comets and asteroids at JPL, was the first of the scientists who disappeared or died. He died on July 30, 2023, at the age of 59. No cause of death was disclosed.
A year later, JPL physicist Frank Maiwald died at 61, with no cause of death disclosed.
Two other Los Angeles scientists are part of the string of deaths and disappearances.
On June 22, 2025, Monica Jacinto Reza, a materials scientist at JPL, disappeared while on a hike near Mt. Waterman in the San Gabriel Mountains.
On Feb. 16, Caltech astrophysicist Carl Grillmair was fatally shot on the porch of his Llano home. The Los Angeles County Sheriff’s department arrested Freddy Snyder, 29, in connection with the shooting. Snyder had been arrested in December on suspicion of trespassing on Grillmair’s property.
Snyder has been charged with murder.
There is no evidence at this point that the deaths and disappearances, which occurred over a span of four years, are connected.
A spokesperson for NASA, which owns JPL, said in a statement on X that the agency is “coordinating and cooperating with the relevant agencies in relation to the missing scientists.
“At this time, nothing related to NASA indicates a national security threat,” agency spokesperson Bethany Stevens wrote. “The agency is committed to transparency and will provide more information as able.”
Representatives from Caltech, which manages JPL, did not immediately respond to a request for comment.

What’s in a Name? For These Snails, Legal Protection
The sun had barely risen over the Pacific Ocean when a small motorboat carrying a team of Indigenous artisans and Mexican biologists dropped anchor in a rocky cove near Bahías de Huatulco.
Mauro Habacuc Avendaño Luis, one of the craftsmen, was the first to wade to shore. With an agility belying his age, he struck out over the boulders exposed by low tide. Crouching on a slippery ledge pounded by surf, he reached inside a crevice between two rocks. There, lodged among the urchins, was a snail with a knobby gray shell the size of a walnut. The sight might not dazzle tourists who travel here to see humpback whales, but for Mr. Avendaño, 85, these drab little mollusks represent a way of life.
Marine snails in the genus Plicopurpura are sacred to the Mixtec people of Pinotepa de Don Luis, a small town in southwestern Oaxaca. Men like Mr. Avendaño have been sustainably “milking” them for radiant purple dye for at least 1,500 years. The color suffuses Mixtec textiles and spiritual beliefs. Called tixinda, it symbolizes fertility and death, as well as mythic ties between lunar cycles, women and the sea.
The future of these traditions — and the fate of the snails — are uncertain. The mollusks are subject to intense poaching pressure despite federal protections intended to protect them. Fishermen break them (and the other mollusks they eat) open and sell the meat to local restaurants. Tourists who comb the beaches pluck snails off the rocks and toss them aside.
A severe earthquake in 2020 thrust formerly submerged parts of their habitat above sea level, fatally tossing other mollusks in the snail’s food web to the air, and making once inaccessible places more available to poachers.
Decades ago, dense clusters of snails the size of doorknobs were easy to find, according to Mr. Avendaño. “Full of snails,” he said, sweeping a calloused, violet-stained hand across the coves. Now, most of the snails he finds are small, just over an inch, and yield only a few milliliters of dye.
