The future of the National Science Foundation is in question after a slew of scientists who serve on the National Science Board, an independent body that promotes the progress of American science and provides advice to the U.S. president and Congress, were abruptly dismissed from their positions Friday by the White House.

All 22 current members of the board, which establishes policies for the National Science Foundation, were terminated, according to Yolanda Gil, a research professor of computer science and spatial sciences and principal scientist at USC Information Sciences Institute, who has served on the board since 2024.

Many of them received a curt email from President Trump’s presidential personnel office.

“On behalf of President Donald J. Trump, I’m writing to inform you that your position as a member of the National Science Board is terminated, effective immediately,” read an email reviewed by the L.A. Times. “Thank you for your service.”

After receiving an email Friday afternoon, Keivan Stassun, a professor of physics and astronomy at Vanderbilt University and director of the Vanderbilt Initiative in Data-intensive Astrophysics, said he reached out to fellow board members. Every member he heard back from — about a third of the board — reported receiving the same termination notice.

For Stassun, a board member since 2022, the termination represented “a wholesale evisceration of American leadership in science and technology globally.”

The White House has not given any reason for dismissing the board members or provided any information on when, or even whether, they will be replaced. A media representative for the NSF directed all questions to the White House. The White House did not respond to questions from The Times.

The National Science Foundation was created more than 75 years ago as an independent federal agency when President Truman signed the National Science Foundation Act of 1950 to boost U.S. science for national security and international competition during the Cold War.

“The establishment of the National Science Foundation is a major landmark in the history of science in the United States,” Truman said back then. “We have come to know that our ability to survive and grow as a nation depends to a very large degree upon our scientific progress. Moreover, it is not enough simply to keep abreast of the rest of the world in scientific matters. We must maintain our leadership.”

The agency, which has a budget of over $9 billion, supports fundamental research and education across all non-medical fields of science and engineering.

“The genesis of it was to recognize that the world was increasingly being won or lost on the basis of scientific and technological capability,” Stassun said. “The National Science Foundation is the singular agency within our government that has as its focus making sure that we stay ahead in basic science, technological developments, training the next generation of scientists and engineers.“

After Trump’s dismissal of the board’s experts, Stassun said, the Trump administration could potentially run the agency directly through the Office of Management and Budget.

“What it means is that there won’t be any practical impediments to the administration essentially enacting their own budget and priorities and ignoring Congress’ directives or congressional law,” Stassun said.

Rep. Zoe Lofgren of San José, the ranking Democrat on the House Science, Space and Technology Committee, dubbed the terminations just “the latest stupid move made by a president who continues to harm science and American innovation.”

The board, Lofgren noted in a statement, is apolitical and advises the president on the future of NSF.

“It unfortunately is no surprise a president who has attacked NSF from day one would seek to destroy the board that helps guide the foundation,” Lofgren added. “Will the president fill the NSB with MAGA loyalists who won’t stand up to him as he hands over our leadership in science to our adversaries? A real bozo the clown move.”

The National Science Board is typically made up of 25 scientists and engineers from universities and industry across the nation. Appointed by the U.S. president, they traditionally serve six-year terms.

Some of the board positions were vacant. The key position of NSF director has been unfilled ever since Sethuraman Panchanathan, a computer scientist and academic administrator, resigned in April 2025.

“Given that the NSF director position has been vacant for a year, and that the NSB’s main role is governing NSF, the agency is left in a very precarious position,” Gil told The Times in an email. “I think this is one more indication of the sweeping changes that the administration is planning for the National Science Foundation.”

Over the last two years, Gil said, the White House has proposed drastic reductions in the NSF budget — a troubling sign, she argued, that basic research in science and engineering and training students are not high priorities for the current administration.

In the last few months, Gil added, the agency had significant reductions of personnel, which she said “jeopardizes the peer review process that the agency is best known for and gives more decision power to program directors.”

In March, Trump nominated James O’Neill, a venture capitalist and biotech investor who served as former deputy secretary of Health and Human Services, to lead the foundation. O’Neill has yet to appear before Congress for a hearing, but Trump’s nomination received a storm of criticism from scientists.

“O’Neill would be the first head of NSF who wasn’t a scientist or engineer,” Dr. Julian Reyes, chief of staff of the Union of Concerned Scientists, wrote in a blog post. “If O’Neill is confirmed as NSF’s director, the Trump administration will further tighten its control over an agency created by Congress to be independent in its work to advance science.”

Traditionally, Gil said, NSF directors have had a solid research career and strong familiarity with NSF processes. O’Neill’s background in finance and investments, she suggested, “may be an indication that the administration has a different idea of how to run a science agency like NSF.”

Already, the Trump administration has purged a raft of scientific advisory boards that provided the federal government with expert guidance. Last year, dozens of experts who provided independent evaluations for biomedical research were dismissed from National Institute of Health science review boards. All 17 members of the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices, which provides federal recommendation on vaccines, were also removed.

In that context, Stassun said he was not surprised when he got the termination letter Friday. “At some point,” he figured, “they would come for the National Science Board, too.”

Going forward, Stassun said he expected the Trump administration to pursue a narrower agenda, from investments in artificial intelligence to building a fleet of Antarctic vessels.

“What we’re likely to see is a collapse of what has historically been a broad investment in American science and technology capabilities,” he said. “The most transformative discoveries are transformative because you can’t predict them in advance, so we invest foundationally in scientists and engineers to do basic science and engineering research.”

One of the board’s chief priorities since he joined in 2022, Stassun said, had been the idea of “talent being the treasure” — developing the best and brightest future leaders and discoverers to ensure a future for American leadership in scientific and technological innovation.

For the board, that meant investing in early science education and strong training for scientists and engineers at all educational levels and in all sectors.

“Discoveries and inventions don’t make themselves, Stassun said. “People do those things. I think there’s a kind of attitude in the current administration that such a worldview is sort of too soft or meek.”

The Trump administration’s interests and priorities, Stassun said, seemed quite different.

“They see the future in, or at least their interest is in, big data centers … not in addition to, but in place of, training human minds to be leading the way,” Stassun said. “It’s a dead end or a bridge to nowhere.”

Even the pioneers of AI will tell you, Stassun said, in many cases, what AI does very well is rapidly synthesizing, consolidating or repackaging existing information. A large language model can only tell you, perhaps very quickly and effectively, what’s already been said.

“Discovery and invention remain the purview of the human mind and creative human genius,” Stassun said. “So, yeah, I think it really does say something pretty foundational to choose to invest only in the one and not the other.”

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 did not immediately respond to a request for comment.

For scientists, measuring the water in a river or a lake is relatively straightforward. It’s much more complicated to figure out how much water lies underground.

After years of research, a team of scientists has finally mapped what remains of these hidden waters across the United States, and they’ve produced the most extensive estimate of the country’s groundwater to date.

Researchers at Princeton University and the University of Arizona took data from about 800,000 wells and applied a machine-learning model to estimate the depth of the water table nationwide.

“Groundwater is out of sight and out of mind for most people,” said Reed Maxwell, a hydrologist at Princeton and co-author of the recent study in the journal Nature. “Knowing how much we have will be helpful in knowing how to use it wisely.”

They incorporated data on the geology of aquifers and estimated down to nearly 1,300 feet, far deeper than most wells.

The scientists say their detailed map and data could help local decision-makers address overpumping from stressed aquifers, and help researchers estimate how much water has been depleted.

California has seriously depleted groundwater in the San Joaquin, Salinas and Cuyama valleys, Ventura County and other places, with some of the fastest rates of water decline in the world.

In parts of the Central Valley, where large farms draw heavily from wells, aquifer levels have plummeted. The U.S. Geological Survey estimates it has lost 128 million acre-feet, comparable to the volume of Lake Tahoe, since pumps started pulling it out in the early 20th century.

That was as of 2019, and water levels have continued to decline.

In the desert Southwest, the groundwater is largely considered “fossil water” because it took millennia to accumulate. So once it is pumped out, it’s in effect gone for good.

Even depleting small amounts of water can be a problem, said co-author Laura Condon, a University of Arizona hydrologist. “We see this in Arizona and in Southern California too, where long before you run out of water, you start disappearing wetlands, disappearing small tributaries.”

The total quantity of water underground is still immense. The scientists found nationwide there is roughly 250 billion acre-feet, or 13 times the volume of the Great Lakes.

Data compiled by lead author Yueling Ma show the Colorado River watershed has about as much groundwater as the volume of the Great Lakes, while California has about 70% of that.

Those are vast quantities, but the researchers said that definitely doesn’t mean there is plenty of water to recklessly use up. Declines in groundwater levels have in recent years caused household wells to sputter and run dry, streams and wetlands to dry up, and land to sink, damaging canals and levees. California’s database of dry wells shows about 6,000 have run dry since 2013, but in the last year, only 13 dry wells were reported. So that problem has slowed down for now. It could soon worsen again.

The new map shows groundwater varies widely across the country. In some places, you have to drill down 300 feet to reach it. In others, it’s just a few feet below the soil.

The map can help scientists studying where slow-flowing aquifers are feeding nature, nourishing streams and wetlands.

Jay Famiglietti, a hydrologist and professor at Arizona State University who wasn’t involved in the research, called the researchers’ map and estimates a “remarkable achievement for modeling and understanding groundwater” in the United States.

The scientists “convincingly show that it is now possible to simulate groundwater depths and availability at very high resolutions,” he said, and they have made their results “accessible and useful for water managers across the country.”

He said the research adds to satellite measurements that scientists now use to track shifts in water over time. What the country still needs, he said, is a “national-scale network of deep groundwater wells” to track the quantity and quality of water all the way down to bedrock.

Two years ago, Gov. Gavin Newsom announced a strategy to save declining salmon. Now, as Rachel Becker reports for CalMatters, members of the Winnemem Wintu Tribe say the state is ending its support for an effort to reintroduce endangered winter-run Chinook to waters upstream of Shasta Lake reservoir, and they feel betrayed.

The Trump administration recently announced it will spend $40 million to begin a plan to raise the height of Shasta Dam, which would expand California’s largest reservoir. As Camille von Kaenel reported for E&E News by Politico, dozens of environmental, fishing and tribal groups sent a letter to Newsom urging him to oppose the Trump administration’s renewed effort to raise the dam.

I followed up to ask Newsom’s office about the idea of raising Shasta Dam. “We aren’t getting distracted by conceptual projects, years from viability,” Newsom spokesperson Tara Gallegos said. Instead, she said the governor is focusing on getting the planned Sites Reservoir built northwest of Sacramento, which “will benefit regions throughout California and is much farther along towards construction.” Gallegos added that the state already is “a significant investor in the project, and the federal government should join us in ensuring this project comes to fruition.”

In the San Joaquin Valley, the Delta-Mendota subbasin has become the fourth farming area to avoid being placed on groundwater probation by state regulators. The State Water Resources Control Board voted this week not to impose enforcement measures on the area, Monserrat Solis reported for SJV Water.
