President Trump’s Cuts to Medical Research
The Trump administration stormed into office, loudly firing workers and closing diversity programs. But behind the scenes, it has also brought biomedical research to the brink of crisis by holding up much of the $47 billion the United States spends on the field every year.
The world’s leading medical labs can be found in the United States, and they rely on grants from the National Institutes of Health. The agency has stopped vetting future studies on cancer, Alzheimer’s, heart disease and other ailments. Trump aides have said they just need time to review spending their predecessors had promised, but it’s unclear what they’re looking for at the N.I.H. or when scholars can expect to start receiving money again.
In today’s newsletter, I’ll walk you through what happened — and why it matters.
A complex machine
Late last month, when the Trump administration froze government grants, a federal judge said it couldn’t just hold back money Congress had agreed to spend. But spending money at the N.I.H., which awards more than 60,000 grants per year, isn’t so simple.
That’s because new grants endure a tortured bureaucratic process. The agency has to notify the public of grant review meetings in The Federal Register, a government publication. Then scientists and N.I.H. officials meet to discuss the proposals. The problem is that the Trump administration banned those announcements “indefinitely.” So new research projects can’t get approved.
In effect, scientists say, the Trump administration is circumventing the court order. Health officials didn’t block research outright, but by shutting down the process, they’re still not spending much of the money Congress allocated to various research goals.
The administration has also proposed other big changes, saying that universities should bear more of the “indirect costs” of research: maintaining lab space, paying support staff. Trump aides say the changes would trim administrative bloat and free up more government money for research.
Labs hit pause
Scientists are panicked, and hundreds of studies are at a standstill, including ones on pancreatic cancer, brain injuries and child health. Last week alone, the N.I.H. canceled 42 of 47 scheduled meetings to assess new grants. Some examples of stalled projects:
-
For years, Steffanie Strathdee at the University of California San Diego has followed drug users to research overdoses, which kill some 100,000 people in the United States each year. Her investigation of H.I.V. infections in that group was ready to begin — but came to an abrupt halt when the N.I.H. canceled a review panel meeting this month. “Everything is absolutely frozen,” she told me. “It’ll just sit there, hanging in limbo.”
-
Anthony Richardson at the University of Pittsburgh was expecting a review panel to weigh a grant application of his on staph infections in people with diabetes, a disease that afflicts more than one-tenth of Americans. It never happened. “I am not 100 percent sure what their motives are,” he said.
In response to all the uncertainty, universities are retrenching. The University of Pittsburgh froze Ph.D. admissions. Columbia University’s medical school paused hiring and spending. The Massachusetts Institute of Technology froze the hiring of nonfaculty employees.
Some lab leaders told me they were making contingency plans to fire scientists. Graduate students are searching for new sources of funding.
What next?
It’s hard to say how long the holdup will last. The Trump administration hasn’t submitted a single new grant review meeting to The Federal Register since a day after it took office. And even if it started adding new ones, the agency traditionally gives several weeks’ notice.
At risk are not only the tens of thousands of grants the N.I.H. awards each year, but also American dominance of biomedical research. Every dollar the agency spends on research generates more than two dollars in economic activity, the N.I.H. has said. Scores of patents follow. By some measures, the United States produces more influential health-sciences research than the next 10 leading countries combined.
The science unfolds across the country, including in red states, where lawmakers have complained about proposed changes to indirect costs.
Those findings often fuel pharmaceutical advancements, laying a foundation for drugs and vaccines long before private funders see such work as worth investing in.
Even Ozempic traces its roots back in part to work at the N.I.H on animal venom. Scientists found that the toxin from Gila monster lizards seemed to have particular physiological effects, helping lead eventually to one of the world’s most profitable and promising drugs.
New advances like those, scientists say, are in danger.

Feeling lonely may take a toll on older adults’ memory — but it may not speed up cognitive decline, according to a new study.
Researchers from Colombia, Spain and Sweden analyzed data from more than 10,000 adults ages 65 to 94 across 12 European countries and found those who reported higher levels of loneliness did worse on memory tests at the start of the study, according to research published this month in the journal Aging & Mental Health.
Over a seven-year period, however, memory decline occurred at a similar rate regardless of how lonely participants felt.

“The finding that loneliness significantly impacted memory, but not the speed of decline in memory over time was a surprising outcome,” lead author Dr. Luis Carlos Venegas-Sanabria of the School of Medicine and Health Sciences at the Universidad del Rosario said in a statement.

“It suggests that loneliness may play a more prominent role in the initial state of memory than in its progressive decline,” Venegas-Sanabria said, adding that the findings highlight the importance of addressing loneliness as a factor in cognitive performance.
The findings add to debate about whether loneliness contributes to dementia risk. While loneliness and social isolation are often considered risk factors for cognitive decline, research results have been mixed.
EXPERTS REVEAL HIDDEN LINK BETWEEN POOR SLEEP AND ALZHEIMER’S DISEASE RISK
The study looked at data from the long-running Survey of Health, Ageing and Retirement in Europe (SHARE), which tracked 10,217 older adults between 2012 and 2019. Participants were asked to recall words immediately and after a delay to measure memory performance.

Loneliness was assessed using three questions about how often participants felt isolated, left out or lacking companionship.
About 8% of participants reported high levels of loneliness at the outset. That group tended to be older, more likely to be female and more likely to have conditions such as depression.
DEMENTIA RISK SIGNALS COULD LIE IN SIMPLE BLOOD PRESSURE READINGS, SAY RESEARCHERS
Researchers found that those with higher loneliness had lower scores on both immediate and delayed memory tests at baseline. Still, all groups — regardless of loneliness level — experienced similar declines in memory over time.
The results suggest loneliness may not directly accelerate the progression of memory loss, though it remains linked to poorer cognitive performance overall.

Experts warn, however, that the findings should not be interpreted to mean loneliness is harmless.
“The finding that lonely older adults start with worse memory but don’t decline faster is actually the most interesting part of the paper, and I think it’s easy to misread,” said Jordan Weiss, Ph.D., a scientific advisor and aging expert at Assisted Living Magazine and a professor at NYU Grossman School of Medicine.
“It likely means loneliness does its damage earlier in life, well before people show up in a study like this at 65-plus,” Weiss told Fox News Digital.
By older age, long-term social patterns may already be established, making it harder to detect when the effects of loneliness first took hold, an aging expert says. (iStock)

“By the time you’re measuring someone in their late 60s, decades of social connection patterns are already baked in,” he said.
Weiss, who was not involved in the research, added that loneliness may coincide with other health conditions, and noted that participants who felt more isolated also had higher rates of depression, high-blood pressure and diabetes. The link, he said, may reflect a cluster of health risks rather than a direct cause.
“While they can go hand-in-hand, it’s not clear that loneliness contributes to dementia,” a psychotherapist says. (iStock)
Amy Morin, a Florida-based psychotherapist and author, said the findings reflect a broader pattern in research on loneliness and brain health, and that the relationship may be more complex than it appears.

“The evidence shows there’s a link between loneliness and cognitive decline but there’s no direct evidence of a cause and effect relationship,” she said. “So while they can go hand-in-hand, it’s not clear that loneliness contributes to dementia.”
Morin added that loneliness, which can fluctuate, may not be the root of the problem, but rather a symptom of other underlying mental or physical health issues.

Research continues to uncover new details on how fasting may help extend life.
A new study published in the journal Nature Communications investigated how intermittent fasting can boost longevity in small worms often used in aging research.
Researchers from the University of Texas Southwestern Medical Center in Dallas compared worms that were fed normally to those that underwent a 24-hour fast in early adulthood and were then fed again, according to a press release.
POPULAR INTERMITTENT FASTING DIETS MAY NOT DELIVER THE HEALTH BENEFITS MANY EXPECT
The scientists measured a variety of factors, including stored fat, gene activity related to fat metabolism and lifespan.
The results showed that the life-boosting benefit did not depend on the fasting itself but on the body’s behavior after eating again.

Study lead Peter Douglas, associate professor of molecular biology and a member of the Hamon Center for Regenerative Science and Medicine at UT Southwestern, suggested that these discoveries “shift the focus toward a neglected side of the metabolic coin – the re-feeding phase.”
“Our data suggest that the health-promoting effects of intermittent fasting are not merely a product of the fast itself, but are dependent on how the metabolic machinery recalibrates during the subsequent transition back to a fed state,” he said.
PEOPLE LOST WEIGHT WHILE EATING SIGNIFICANTLY MORE FOOD — HERE’S THE SECRET
“Our findings bridge a gap between lipid metabolism and aging research,” he added. “By targeting aging, the single greatest risk factor for human disease, we move beyond treating isolated conditions toward a preventive model of medicine that enhances quality of life for all individuals.”
Lauri Wright, director of nutrition programs at the University of South Florida’s College of Public Health, called this a “high-quality” study that adds an “important nuance to how we think about fasting and longevity.”
Intermittent fasting typically involves limiting meals to an eight-hour daily window or fasting every other day. (iStock)
The benefits of the refeeding phase after fasting were “especially interesting,” Wright, who was not involved in the study, told Fox News Digital.
“The researchers showed that longevity was linked to the body’s ability to turn off fat breakdown after fasting, allowing cells to restore energy balance,” she reiterated.

“From a scientific standpoint, that’s a meaningful shift because it suggests fasting is not just about burning fat, but about metabolic flexibility.”

Fasting may support longevity through triggering metabolic switching, enhancing cellular repair and stress resistance and improving markers like insulin sensitivity, research shows.
Limitations and cautions
Although this study provides “important insight” on the power of refeeding, Wright noted that the findings should be approached with caution, as the study was done on worms and cannot always be translated to humans.
“Additionally, it explains how a process might work in a controlled lab condition rather than real-world eating behaviors,” she added as a limitation. “Finally, the study is short-term and doesn’t give us the long-term translation on lifespan outcomes.”
The review found intermittent fasting was barely more effective than doing nothing, according to the study authors. (iStock)
Wright cautioned that fasting is “not a magic solution for longevity, and how you eat overall matters more than when you eat.”
“I advise, first and foremost, to focus on diet quality, including a variety of fruits and vegetables, healthy fats and minimally processed foods,” she said.

For those who are considering fasting, it’s better to stick with a moderate plan — like a 12- to 14-hour overnight fast — rather than going to extremes, Wright said. After fasting, she recommends focusing on well-balanced meals.

Several groups of people should be cautioned against fasting, according to Wright, including those with diabetes who are on insulin or hypoglycemic medications, those who are pregnant or breastfeeding, anyone with a history of eating disorders and older adults at risk of malnutrition.
Anyone considering intermittent fasting should consult with a doctor before starting.
