The Trump administration’s war on science is no secret. The actions taken to fire scientists, to cut back research funding to universities, the blatant efforts to censor and politicize research have been out in the open since the second disastrous Trump term began.

Why Trump and the top echelon of his team have done this is a secret. One of the greatest strengths of the U.S. has been its leadership in science and medicine. The Trump regime has squandered that leadership. Why? Is it malice? Stupidity? I can’t figure it out.

Of one thing, there is no doubt: Trump and his cronies are seeking to destroy America’s leadership in science and medicine.

A team of six reporters from The New York Times documented the damage done. What they cannot explain is why.

The story begins:

The warning, buried in an obscure government report this summer, was unflinching.

The Defense Department’s vaunted network of research laboratories — whose scientists helped develop satellite communication, radar technology, and even the computer mouse — was in trouble.

The labs lost a significant share of their staff last year, largely in response to the Trump administration’s efforts to thin the federal work force, the report found. Refilling critical positions was proving difficult due in part to President Trump’s demand that new hires be screened for their loyalty to his goals. The report, issued by the Pentagon, pointed to “potentially grave consequences for the future of national defense.”

The turmoil inside scientific research has extended beyond the Pentagon. The Energy Department, a key hub of nuclear and quantum research, has lost more than 1,000 scientists and technical staff. The National Science Foundation, for decades a primary backer of long-term, foundational research, has withheld more than $1 billion in funding. And at the National Institutes of Health, the biggest funder of medical research, officials delayed or canceled more than 2,000 grants to biomedical researchers focused on topics such as Alzheimer’s, cancer and other diseases.

Under Mr. Trump, the federal government is still spending roughly as much on research — about $200 billion this year — as the administrations that came before. Scientists across the country are still receiving grants; universities are still being funded. But beneath the surface, the system of federally funded science that helped make the United States a global superpower is under intense strain from Trump policies, jeopardizing the nation’s advantages in defense, medicine and technology, a New York Times examination has found.

The White House regularly proclaims that it is advancing American interests. Yet its actions are eroding the country’s scientific edge as global rivals challenge U.S. dominance in fields that will help define the 21st century, according to interviews with scientists, university leaders, government officials and analysts and a review of documents and budgets.

The damage is the byproduct of three pillars of Mr. Trump’s broader agenda.

One is the sweeping job cuts and grant cancellations engineered last year by the so-called Department of Government Efficiency, the Elon Musk-led effort that viewed much of federal spending as wasteful and whose effects are still reverberating across the bureaucracy.

A second is the administration’s continued pressure on research universities, in which the White House used funding cuts to push schools into adhering to its demands for ideologically driven policy shifts.

The third is a campaign by Mr. Trump’s budget director, Russell T. Vought, to impose more political control over how the government spends money appropriated by Congress, further infusing politics into decisions around scientific research.

If not for the courts curbing the administration’s campaign against universities and lawmakers in both parties rejecting cuts to research funding, the impact on science would have been far deeper. Still, the effects of the broader agenda have rippled through nearly every facet of the nation’s research machine.

Aspiring scientists have seen their career paths thwarted, with fewer available spots for Ph.D. students. The number of Ph.D. applications from foreign students, typically a significant share of U.S. science programs, shrank by 21 percent this year at leading universities, according to data gathered for the Association of American Universities. Total Ph.D. admissions at those schools have dropped as universities try to make do with less resources.

Even the agencies working on topics that Mr. Trump and his aides have called priorities — including national defense, artificial intelligence, quantum computing and nuclear energy — have been depleted.

Taken together, the changes underscore how Mr. Trump’s policies have disrupted scientific research beyond the areas the administration has targeted more directly, such as vaccines and climate science, endangering U.S. power and pre-eminence.

By many measures, China is closing the gap with the United States as the world’s research leader. Some organizations that rank global universities show China’s best schools increasingly displacing American universities at the top. And the impact of Chinese research papers, as measured by citations from other scientists, has caught up with the United States, according to Clarivate, a data and analytics company.

By the time the full consequences of the administration’s actions become apparent, experts warn, it could be too late to fix. That’s because basic research funded by federal grants often takes decades to mature into the technology, medical treatments and consumer products that change American life.

Federally funded work on atomic clocks starting in the late 1940s, for example, paved the way for GPS technology. In 1976, federally funded research yielded a major discovery about the origins of cancer-causing genes, which led to a Nobel Prize and, two decades later, lifesaving cancer drugs. Some of the early precursors to artificial intelligence date to U.S.-backed research in the 1980s, which used an algorithm to teach neural networks to learn from mistakes.

“Science is the long game,” said Marcia McNutt, who was president of the National Academy of Sciences, the country’s top scientific advisory body, until this summer. “By the time we no longer win any Nobel Prizes, we will have lost the capacity to ever recover.”

In response to The Times’ reporting, officials from the White House, Pentagon and other science agencies disputed that administration policies were hampering science. Rather, said White House spokeswoman Liz Huston, the administration is reinvigorating American science by transforming organizations in need of change.

“President Trump is ushering in a new golden age of American science by modernizing our research institutions, refocusing on ambitious national missions, and fully leveraging super intelligence for scientific discovery,” Ms. Huston said in a statement, using Mr. Trump’s preferred term for artificial intelligence. “Revitalizing our national scientific enterprise requires supporting the best American scientists and funding the best research based on merit.”

The White House said the administration has expanded a number of programs that support young researchers, and noted that the decision to reduce Ph.D. admissions this year was made by the universities themselves. The Association of American Universities said schools’ decisions to reduce admissions were largely the result of “federal research funding uncertainties.”

The White House also said that most of the scientists who have stopped working for the federal government since Mr. Trump came back to office were not fired, but instead left voluntarily. And it noted that the methodologies for ranking universities, such as comparisons between the United States and China, are limited.

The rest of the world now sees an opportunity.

Australia, for example, announced its “global talent attraction program,” calling it “an urgent and unparalleled opportunity to attract the smartest minds leaving the United States.” Canada dedicated more than $1 billion to bring in 1,000 international researchers, drawing American leaders in fields such as biochemistry and neuroscience.

Even China, a country not known for academic freedoms, has been luring researchers away. A winner of last year’s Nobel Prize in Chemistry left the University of California, Berkeley, to lead an institute in Beijing using artificial intelligence to accelerate the discovery of new materials — two fields the Trump administration has said it wants to dominate.

A Postwar System Shaken to Its Core

The roots of the United States’ science empire can be traced to a landmark 1945 report issued during the Truman administration, “Science: The Endless Frontier.” It described a vision, inspired in part by the Manhattan Project that led to the atomic bomb, for how science would power U.S. dominance in the world.

The federal government went on to establish a network of science agencies with distinct missions. The National Science Foundation supports theoretical or experimental work, which often lays the groundwork for future technologies years or even decades later. The Department of Energy was established to pursue advances related to power generation, as well as managing the nation’s nuclear arsenal. NASA, created in response to Soviet advances in space, put a man on the moon. The National Institutes of Health, which traces its roots to 1887, funds biomedical advances.

The federal government also provides tens of billions of dollars each year to the nation’s research universities while funding national labs, private industry and other institutions — a system built up over 80 years by presidents and lawmakers from both parties.

In less than two years, Mr. Trump has shaken that system to the core.

The upheaval began early in the administration.

DOGE engineered staff firings, and encouraged others to resign across the federal bureaucracy. Within a year, N.I.H. staffing had shrunk by one-fifth. The N.S.F.’s ranks were reduced by a third. Even NASA, which shrank less than other science agencies, lost 20 percent of its employees with Ph.D.s. Those who left included its chief scientist, a climate science expert whose job the administration eliminated.

NASA said it will keep recruiting staff as needed. In a statement, Nicky Fox, the associate administrator for NASA’s Science Mission Directorate, said the agency is working to get “more science into space for lower cost.”

DOGE and the White House directed agencies to search for terms in grant descriptions that might reveal science the administration viewed as liberal, including anything that appeared to promote diversity, equity and inclusion.

The cuts cascaded through the country.

Ann D. Cohen, a neuroscientist who co-directs an Alzheimer’s research center at the University of Pittsburgh, had been working on a five-year study looking at how people’s exposure to stress and health problems earlier in life can affect their odds of developing the disease.

The research was critical to developing better treatments and health interventions, Dr. Cohen said. “If the triggering event is poor cardiovascular health in midlife, we can actually deploy public health strategies to improve those things, and potentially have an effect on Alzheimer’s,” she said.

Recruiting people from different backgrounds was difficult, because people who volunteer for scientific studies tend to have higher than average incomes and education levels. So Dr. Cohen and her colleagues recruited from rural Western Pennsylvania, whose residents were more likely to be white and low-income, as well as from Black communities in Pittsburgh.

This past August, the N.I.H. terminated the grant, effective immediately, on the grounds that the project was focused on structural racism — an argument that fundamentally misunderstood the work, Dr. Cohen said.

Emily Hilliard, a spokeswoman for the U.S. Department of Health and Human Services, which includes the N.I.H., did not comment on specific grants. In a statement, she said N.I.H.’s commitment to Alzheimer’s research has not decreased.

“N.I.H. is focused on funding innovative projects led by a new generation of health researchers, and on allocating funds for research that will lead to better health for the American people,” Ms. Hilliard said.

Some researchers who lost funding acknowledged having framed their projects in the language of D.E.I. But, they argued, that was what the Biden administration had emphasized.

Jessica L. Rosenberg, director of education for the Quantum Science and Engineering Center at George Mason University, had received N.S.F. funding to research ways to encourage more American students to seek careers in quantum technology, an emerging field that has led to innovation by vastly expanding computing power.

The N.S.F. canceled the grant last year, about four months after the project started. Dr. Rosenberg said she suspects the grant was targeted because her application mentioned students from diverse backgrounds.

“That was what we were supposed to be doing at the time,” she said in an interview.

Trump administration officials argue that the push to incorporate D.E.I. degraded science, and that scientists who embraced the approach had themselves to blame for losing support.

“We cannot afford for America’s scientists to be in the business of scoring points for an ideological agenda,” Michael Kratsios, Mr. Trump’s science adviser, told a meeting of scientists last year.

A Dilemma for Universities

Mr. Trump and his aides returned to the White House wanting to punish elite schools like Columbia and Harvard, ostensibly for transgressions like tolerating antisemitism.

But when cuts to research funding became the White House’s weapon of choice, professors and administrators had to decide whether to fight or acquiesce.

Harvard sued. Other schools negotiated. And even at universities that were not explicitly targeted, researchers made changes in hopes of keeping federal money that was foundational to their work — softening the language in their proposals, narrowing their projects and debating the line between fair-game government oversight and improper political interference.

The cuts fell across disciplines. Projects on epilepsy, Lou Gehrig’s disease, tuberculosis and even astronomy outreach and education sputtered. Work on cancer and heart rhythms was imperiled.

The administration ultimately restored billions of dollars in funding, either because of court orders or settlements with universities. But researchers said the interruptions and changing priorities delayed or derailed experiments.

“You can’t run a research operation when you have to constantly pivot,” said Dorota Grejner-Brzezinska, vice chancellor for research at the University of Wisconsin-Madison, which was swept up in the administration’s funding cuts and participated in more than a dozen legal challenges.

“The current state of affairs is that it’s really very hard to plan long term,” she added, “and research is a long-term kind of enterprise.”

May Mailman, a former White House aide who helped lead the pressure campaign against universities, said the administration wasn’t overly concerned about the effects on research. Funds taken away from one university could eventually make their way to other schools whose behavior and ideology the White House approved of, she said. In the meantime, Ms. Mailman said, the administration tried to minimize the disruption to fields of research it supported, including artificial intelligence and some types of energy.

But much of the work coming out of universities, she said, may not have merited the taxpayer money going into it.

“There’s a feeling that there is more spent on research than comes out of it — that the system is a little bit broken,” Ms. Mailman said.

The Hunt for Woke

The administration also sought deep funding cuts to federal science agencies. Last year, when Mr. Vought presented the administration’s annual budget request to Congress, he called for reducing research funds at the National Institutes of Health by 41 percent; cutting the National Science Foundation by 55 percent; and reducing NASA’s budget for science by almost half. No previous administration, from either party, had sought such deep cuts.

Congress rejected those cuts. But Mr. Vought began finding novel ways to slow grants and redirect funds.

One of the offices that Mr. Vought targeted in his budget request was the N.S.F.’s “woke social, behavioral, and economic sciences” — an apparent reference to an N.S.F. division that funded social science. Not long after, the division began reducing its grants. 

An N.S.F. spokesman, Michael England, said in a statement that the agency’s funding decisions “reflect a strategic alignment of resources in a constrained fiscal environment.”

The loss of those funds affected researchers like Priti Shah, chair of the University of Michigan’s psychology department. Dr. Shah had applied for a grant to study how people evaluate and make decisions based on scientific information. In the summer of 2025, the N.S.F. told her that her application had been put on hold because of funding issues. It was later rejected entirely.

“It is so important to understand what people assume and what errors they make when they’re thinking about science,” Dr. Shah said. “People are very poor at reasoning about scientific evidence.”

An Innovation Engine ‘at Risk of Stalling’

The administration’s actions also hurt agencies central to its political agenda.

The Defense Department’s assessment of science and research capabilities published this summer said changes during the first year of the Trump administration had degraded the department’s highly regarded network of research laboratories, due largely to DOGE cuts and obstacles to hiring.

“Without a swift and sustained reversal of these policies,” the report warned, the Defense Department’s “innovation engine is at risk of stalling.”

The labs lost about 14 percent of their staff, the report found. Among those mentioned were the Naval Sea Systems Command, charged with developing ships and weapons; the Air Force Research Laboratory, which helped develop stealth aircraft and laser systems; and the Army’s Aviation & Missile Center.

External research laboratories, which are funded by the Pentagon but staffed by civilian researchers and develop technology for use by the military, were also suffering from the administration’s policies, the report said.
