National Institute of Health (NIH) Ended Nearly 800 research projects are sleeping and cooking significant funds in the entire scientific field. nature An unprecedented cut analysis.
The US President Donald Trump began to purify the research that NIH supported the topic that was a problem within 50 days, and continued to expand the list and continued to expand the list, including studies on the subject. covid-19 In the wrong information. More than 30,000 scientists in NIH supported their funds had to stop their work after receiving a notice of “no longer fermented agency priorities.”
To understand the scope and width of this behavior, it has been more than $ 2.3 billion allocated to US researchers. nature I have reached a scientist -led effort to track these cuts (see ‘How reference nature We analyzed NIH’s subsidies with supplementary information). According to our analysis, the project theme, the NIH research institute and the US, had the biggest impact.

Subsidy
NIH is so far Applicant in the world’s largest biomedical research fundThe annual budget paid US $ 47 billion for more than 60,000 subsidies. This scale means that the funds of the institution cannot be replaced by science, says Shirley Tilghman, a molecular biologist and president of Princeton University.
nature‘The analysis of the analysis shows that 17%of the projects that have been terminated so far have been examined by 29%and 29%of Covid-19 and 29%(see’ Ended subsidies’). Although this represents less than 4% of all topics awarded to all topics raised in 2024. that. Another potential reason is that HIV/AIDS has an unbalanced impact on sexual and gender minorities (LGBT+). erase On the first day in the office, I signed an execution order. On January 20, the US government instructs the US to admit that it may be different from sex when the individual’s gender is born.
The largest science field due to the reduction of NIH is the health of the transgender people and a wider LGBT+ community, which reduces about half of the subsidies compared to NIH’s funding in 2024 (see ‘Fields Under Fields’).

Tilghman rejects these actions “a small but substantial ratio of an important question of important questions about health.” “You can’t get rid of part of the population with an administrative order, but you can harm it.”
The National Institute Institute Institute Institute Institute Institute was a hammer (see ‘US Nih’s most lost’). Five out of five of the NIH research institutes and the center had the greatest influence of this subsidy. Last week, it was deployed on administrative leaveIt was full of dismissal and restructuring in HHS.

Geographical impact
Trump and his Republican allies said they wanted to worry about the elite university at the ‘wake’ left -wing university. The end of the subsidy was now voted to Trump in 2024 and damaged the scientific enterprises of a research institute of a research institute for ‘reduction of subsidies by the state’ (reduced subsidies of the government). In 2024, Blue State Washington State was the most hit by the end of subsidies, and in 2024, with North Carolina, it was the most hurt compared to how many NIH funds were over a year.
However, the administration not only reduces NIH subsidies in the richest universities, but also occurs in small state schools and black universities, says Scott Delaney, a historian at Harvard TH CHAN Public Health College in Boston, Massachusetts. Database nature Used for analysis. Data science, headquarters headquartered in Berkeley, California, Ropensci, executive director of Ropensci, his collaborator Delaney, his collaborator Delaney, and his collaborative worker, to scientists, to scientists in a listed list of HHS posts on the weekly website. I requested to submit information about the termination.

Trump’s team Columbia aimed at research subsidies.The administration canceled $ 400 million in college because Jewish students failed to protect them from harassment. The campus protests the war of Israel in Gaza.
Columbia, unlike other universities that have lost NIH subsidies related to the administration, have been canceled much more than other universities. nature I searched all NIH subsidies that terminated the keywords of the officials. The federal agency was ordered to searchIncluding ‘diversity’, ‘barrier’ and ‘marginalized’. NIH terminated 89 subsidies in Columbia and lost three subsidies in this category, compared to the second most terminated institution in EMORY University in Georgia Atlanta, including four large words. This indicates that the administration focused less on the topic of concern and focuses more on reducing a certain amount of funds in Columbia. For example, one of the cut subsidies was the title. ‘Long -term exposure to simultaneous occurrence of arsenic and uranium in public and personal drinking waterWe examined the connection between arsenic and chronic heart and kidney disease.
After the end of these subsidies, the Trump administration threatened the same treatment at several other elite universities that received billions of research funds. natureThe analysis of the database is “safe because this subsidy is studying synapses in fruit flies,” said Delaney. “If you are in the target institution, it is not.”
Normalization of termination
In the past, it was very rare for subsidies to end, saying that severe illegal acts, performance or frauds were not good, and a former senior employee of NIH called for anonymity with fear of retaliation. In this case, the institution often has the opportunity to solve the situation, the former workers said.
“So far, subsidies have been assumed that they will support five years of funding unless they do good things and do not work foolish.” “Now it’s gone.”
This uncertainty, combined with hostility to higher education institutions, has already had a cold effect. More than 75% of informal respondents nature Survey of scientists They said they are considering leaving the United States.
The union of 16 state lawyers and groups related to the researchers raised two legal issues to overturn subsidies and said, “NIH banned NIH to prevent reckless and illegal fuzzy supporting research by NIH supporting research by NIH, which is supported by an infamous topic and population. natureQuestions about litigation.
