Researchers at the University of Wisconsin-Madison School of Medicine and Public Health have shown a new AI tool was successful at flagging patients at risk of opioid addiction and at reducing hospital readmissions.
Members of the UW-Madison community gathered Wednesday morning in Washington, D.C. ahead of their lobbying day on Capitol Hill.
“The reality is we’re certainly facing some interesting, challenging times here at the federal level,” said Craig Thompson, vice chancellor of university relations at UW-Madison. “There’s obviously potential cuts to research and other programs, and there’s just a great deal of uncertainty on campus.”
Researchers at the University of Wisconsin-Madison’s School of Medicine and Public Health have developed an artificial intelligence-driven tool to identify hospital patients at risk of opioid use disorder.
The study, led by researchers from Penn State’s College of Medicine and the University of Wisconsin-Madison, conducted a clinical trial to see if improved thinking can treat physical pain over time—and the benefits lasted up to a year.
The University of Wisconsin-Madison has lost at least $12.6 million in anticipated research dollars after President Donald Trump’s administration recently canceled four of its research grants, part of a national crackdown on funding for transgender issues, COVID-19 and diversity.
April is Parkinson’s Disease Awareness Month. Dr. Laura Buyan-Dent, a UW Health neurologist, talks about this neurodegenerative disorder.
In his new biography “Saving Hearts and Killing Rats: Karl Paul Link and the Discovery of Warfarin” (HenschelHAUS Publishing), veteran Madison journalist and author Doug Moe recounts the steps from hay to medicine while also building up a portrait of Link, a University of Wisconsin-Madison biochemist with a propensity for battling authority.
Doctors and researchers at the University of Wisconsin-Madison School of Medicine and Public Health have developed an artificial intelligence tool to ensure some of our most vulnerable patients, those battling opioid use disorder, don’t fall through the cracks.
“The medical chart is full of information and it’s overwhelming, and our human brains just can’t process everything,” Dr. Majid Afshar said.
Doctors theorized Treyson could have cerebral palsy or Angelman syndrome, a rare genetic syndrome that causes intellectual disabilities, difficulty walking and talking and seizures, many of the symptoms he possessed. Genetic testing was done. Nothing matched.
That changed in 2021 when the UW-Madison’s Center for Human Genomics and Precision Medicine began the Undiagnosed Disease Program, making it the second of its kind in the state. Part of the University’s School of Medicine and Public Health, it is often the last stop for patients who are looking for answers.
Steve Ackerman and Jonathan Martin, professors in the UW-Madison department of atmospheric and oceanic sciences, are guests on WHA radio (970 AM) at noon the last Monday of each month.
The next generations of potential doctors, researchers and scientists spent the weekend getting a close look at all that UW-Madison has to offer.
The event was part of UW’s campus-wide science open house called “Science Expeditions.” The hands-on experiences showcased dozens of science venues, including the UW Health Carbone Cancer Center.
At the University of Wisconsin–Madison’s Carbone Cancer Center, dedicated researchers are expressing deep concerns over proposed federal funding cuts that they say could significantly impede advancements in breast cancer research.
A dangerous bird flu, in other words, was suddenly circulating in mammals — mammals with which people have ongoing, extensive contact. “Holy cow,” says Thomas Friedrich, a virologist at the University of Wisconsin–Madison. “This is how pandemics start.”
The award is well deserved, says Brian Rebel, a particle physicist at the University of Wisconsin–Madison. “Finding the Higgs [boson] in 2012 was a once-in-lifetime event, but it was only the first step,” Rebel says. Since then, LHC scientists have been pinning down the mass of the Higgs and its interactions, as well as discovering 72 new particles, investigating antimatter and probing the nature of the ‘quark–gluon plasma’ that existed soon after the Big Bang. “It takes a small army to create the tools to test and validate these results,” says Rebel.
“There are some articulated bones that are nearly absent in other metoposaurid bone beds in North America, and completely unknown for Buettnererpeton,” study co-authors Dave Lovelace and Aaron Kufner, who are both geoscientists at the University of Wisconsin-Madison, tell Popular Science’s Andrew Paul.
“Like other metoposaurids, it probably spent most, if not all, of its life in the water eating fish, other amphibians, or anything unfortunate enough to venture too far into the water,” University of Wisconsin-Madison paleolontologists and study co-authors Dave Lovelace and Aaron Kufner told Popular Science.
“The optimal monetary response is to stimulate the economy, raising aggregate income and boosting demand for imported goods,” wrote Minneapolis Fed economist Javier Bianchi and University of Wisconsin-Madison assistant professor Louphou Coulibaly.
Study first author Aaron Kufner, a geologist at the University of Wisconsin-Madison, and colleagues uncovered fossils of Buettnererpeton bakeri in a Wyoming fossil bed called Nobby Knob.
“This assemblage is a snapshot of a single population rather than an accumulation over time,” Kufner said in a statement. The discovery “more than doubles the number of known Buettnererpeton bakeri individuals.” Alongside the B. bakeri fossils, the team also found fossilized plants, bivalves and fossilized poop, called coprolites.
The Trump administration cut funding for social security research programs across the country, including one at UW-Madison. We talk the director of the local program about how its research has helped shape public policy and what impact these cuts will have.
Learn to appreciate insects, with guidance from local artist Jennifer Angus, entomologist P.J. Liesch, bumblebee expert Judy Cardin and more.
“Parents and kids are very aware of the narrative and very worried,” says Megan Moreno, an adolescent-medicine physician at the University of Wisconsin–Madison. That sparks family battles over screens — and leaves parents unsure what to do.
Christine Schwartz, a sociology professor at the University of Wisconsin at Madison, shared data with me on trends in the educational profile of heterosexual married couples from 1940 to 2020. According to her calculations, in 2020, American husbands and wives shared the same broad level of education in 44.5 percent of heterosexual marriages, down from more than 47 percent in the early 2000s.
A few years ago, D’Orazio spoke with Madison family medicine physician, Dr. James Bigham, about a program to train doctors and medical students at University of Wisconsin-Madison about how to talk to patients about firearms.
D’Orazio’s first question to Bigham: How many of these doctors know anything about a gun? “How are they going to answer questions from their patients if they have never touched a gun, shot a gun, know what a bullet is?” he said. “That’s where I come in.”
Some researchers, including John Womersley, a former chief executive of the UK Science and Technology Facilities Council, and Tulika Bose, an LHC physicist at the University of Wisconsin–Madison, want to see higher-energy machines developed as quickly as possible.
No dairy is pathogen-free, even with the best precautions, said John Lucey, a food science professor who has studied raw milk extensively. Harmful bacteria are in the soil, in the digestive tracts of cows and in the poop they deposit, Lucey said.
Scientists at the University of Wisconsin-Madison recently investigated the matter, NPR reports. For their 2024 study, they asked 1246 dog owners to examine their pet’s behaviors around screens. Eighty-six percent (1077) of participants stated that their dogs appeared to watch the content. Additionally, most animals exhibited behaviors associated with excitement.

The Social Security Administration axed the Retirement and Disability Research Consortium (RDRC), a federally funded research program studying demographic trends and social security policy impact.
“I like to always say that we know less than what we don’t know,” said Gavin Dehnert from Wisconsin Sea Grant and University of Wisconsin-Madison. “That’s partially due to the fact that the PFAS have really hit the scientific radar in the last seven [or so] years.”
Scientists at the University of Wisconsin–Madison said they are struggling to advance study of a potential new epilepsy treatment after the Trump administration’s pause on grant review meetings by the National Institutes of Health.
“We thought this was a one-off: one bird to one cow, and we wouldn’t see that again,” says Peter Halfmann, a virologist at the University of Wisconsin-Madison’s Influenza Research Institute.
Yet the more severe human cases are concurrent with the spread of a recently mutated, potentially more dangerous version of the virus called the D1.1 genotype. D1.1. is now circulating among wild birds and poultry, and it has spilled over into dairy cows at least twice in 2025, according milk testing data from the Agriculture Department. With D1.1, Halfmann explains that the threshold for cross-species transfer is “much lower than we previously thought.”
Travis Pickering, a paleoanthropologist at the University of Wisconsin–Madison, who helped discover, identify, and describe the fossil, says he was “ecstatic” when he saw the bones.
“A find like this, in this context — that is, millions of years old and from a cave, which is extremely dynamic in terms of things like the build-up sediment, rockfall from the roof, the activities of prehistoric animals that dwelled in it, including eating and chewing bone — is as rare as finding hen’s teeth,” he says. “I couldn’t be happier.”
The vast majority of raw milk cheese should be safe after the 60-day aging window, according to Keith Poulsen, DVM, PhD, a clinical associate professor of medical sciences at the University of Wisconsin-Madison School of Veterinary Medicine.
“We have a lot of history and data to back that up,” Poulsen told Verywell in an email. “Unfortunately, the data from Cornell suggests that if raw milk cheeses were made on an affected farm, they would not be recommended for consumption.”
Simon Gilroy is a professor of botany at the University of Wisconsin-Madison who regularly designs spaceflight experiments with NASA. When asked if he thinks we are using astrobiological research enough to improve our sustainability on Earth, Professor Gilroy pointed to the discourse around urban farming, an approach which involves moving some elements of cultivation and productivity into cities instead of using agricultural fields.
Speaking to Interesting Engineering, Professor Gilroy observed that urban environments have many of the same problems as growing plants in space, including challenges around water delivery, maintaining environment within the desired parameters and dealing with pathogen outbreaks. “So there’s a lot of technology development going on in space, which has real applications when you come back to thinking about those kinds of applications on Earth,” he noted.
Anne Morgan Giroux is pretty sure the cure for epilepsy ‒ or at least a long-term solution for millions ‒ is sitting in a university lab in Madison, Wisconsin. She and a team of researchers need just $3.3 million to push it across the finish line.
The problem: That $3.3 million solution is on indefinite hold as President Donald Trump and his administration slashes government spending. The money would have been awarded as grants from the National Institutes of Health to launch human trials. Epilepsy affects about 1% of U.S. adults, or around 3 million people.
Already DOGE has canceled many contracts at Social Security, just as it has at many other federal agencies. A DOGE-run website late last week listed $50.3 million in cost savings from these canceled agreements. That included funding for a University of Wisconsin at Madison study project to understand how to prevent impostor scams. Government impostor scams — most commonly pretending to be from the Social Security office — resulted in estimated losses of at least $577 million last year, often by conning seniors into sharing personal data, according to the agency’s IG office.
“When you cut resources like this, there’s always room to make things more efficient. But you also could make things worse,” said Cliff Robb, a University of Wisconsin professor who has studied impostor scams. “You could end up making fraud worse.”
The bright evening colors come when small particles in the atmosphere cause light to scatter, explained Steven Ackerman, professor of meteorology at University of Wisconsin–Madison, in an online article.
“If the path is long enough, all of the blue and violet light scatters out of your line of sight,” Ackerman said. “The other colors continue on their way to your eyes.”
Days before his flight to Argentina, a UW-Madison researcher lost a Fulbright award from a federal funding freeze.Under President Trump’s administration, the U.S. State Department froze funds in February for international education programs. That includes the Fulbright Program, which allows scholars to conduct research overseas.
For one UW-Madison researcher, the freeze put more than a year’s worth of planning down the drain. “There’s a lot of anxiety in the scientific world now,” said UW-Madison professor emeritus, Richard Lindroth.
Women at the University of Wisconsin conduct groundbreaking research every day to advance their fields of study and contribute to a better understanding of the world.
UW ranks sixth in the nation for research universities among private and public universities, according to the National Science Foundation’s annual ranking. Women in research, specifically in STEM areas, are still underrepresented in research funding, according to a study by JAMA.
UW-Madison Professor Sterling Johnson leads one of the world’s largest and longest-running studies of people at risk for Alzheimer’s disease. His team aims to diagnose the disease years before people develop symptoms and then identify ways to slow its progression.
“A key problem we are trying to solve is how we can diagnose the disease earlier, before people even develop symptoms,” Johnson said during a campus news conference. “Early diagnosis allows time for individuals and their families to take control of their situation, maintain good quality of life, take steps to protect brain health and learn about treatments.”
A study by UW-Madison sociology professor Michael Light and two others of crimes committed between 2012 and 2018 found U.S.-born citizens were more than two times more likely to be arrested for violent crimes than immigrants, 2.5 times more likely to be arrested for drug crimes, and more than four times more likely to be arrested for property crimes.
The 62-mile Yahara River is fed by a 536-square-mile watershed that covers about a quarter of Dane County. It includes a mix of urban and agricultural land and is populated by more than 370,000 people, according to the Center for Limnology at UW-Madison.
Shane Hubbard, a research scientist at the University of Wisconsin, explained that the wind gusts were similar to tornado damage.
“Those are like EF0, EF1 tornado winds in terms of… the dynamics are different, but the wind speeds are the same,” Hubbard said.
A three-year grant funded by Wisconsin Partnership Program, a grantmaking program within the University of Wisconsin School of Medicine and Public Health, is backing research into how the reduction of certain proteins could be actualized through gene editing of soybean and corn, Professor of Medicine and Vice Chair for Biomedical Research in the Department of Medicine Dudley Lamming said.
Randy Jackson, a professor of grassland ecology at University of Wisconsin-Madison who was not involved in the study, said he has found similar results in his own research showing that grass-fed beef has higher emissions assuming the same demand. In fact, Eshel’s team cited his work. But he worries that the study is too focused on minimizing emissions “without concern for the environmental impacts beyond GHG load to the atmosphere,” like biodiversity and soil and water quality, he wrote in an email.
“It wasn’t that they were taking higher or lower doses, but that they were taking it, which does speak to this idea of dampening inflammation,” said Nate Chin, MD, medical director for the Alzheimer’s Disease Research Center and the Wisconsin Registry for Alzheimer’s Prevention at the University of Wisconsin-Madison.
Kate Phelps thinks the way society talks about how young girls use the internet is too simplistic. A big part of that, she says, is because culture spends a lot of time scrutinizing pre-teen girls, but we rarely talk to them about their experiences. Phelps, a University of Wisconsin-Madison women and gender studies researcher, wanted to change that.
Her new book, “Digital Girlhoods,” is based on her conversations with 26 different girls between the ages of 10 and 13 — an age group often referred to as “tweens” — about their feelings about social media.
Wisconsin farmer Andy Diercks sits on a red Memorial Union Terrace chair in the middle of a farm field, holding a potato in his left hand. “It’s amazing all the work that goes into growing this little guy,” he says to Amanda Gevens, UW-Madison chair of plant pathology, who sits across from him. “The research you’ve done over the past decades is critical to grow a good quality crop.”
According to Sanjay Limaye, a scientist working at the University of Wisconsin–Madison Space Science and Engineering Center, “Venus has a potential to harbor conditions for iron- and sulfur-centered metabolism.”
“Some of these surveys allow us to know if people are being successful in college. It tells us where those students are enrolled in college and where they came from. For example, COVID impacted everyone, but it had a disproportionate impact on specific regions in the U.S. and specific social and socioeconomic groups in the U.S.,” said Taylor Odle, an assistant professor of educational policy studies at the University of Wisconsin at Madison.
“Post-COVID, states and regions have implemented a lot of interventions to help mitigate learning loss and accelerate learning for specific individuals. We’ll be able to know by comparing region to region or school to school whether or not those gaps increased or reduced in certain areas.”
This canceled grant — which funded research into retirement that informed federal policymaking — has impacted the work of more than 50 people at the University of Wisconsin-Madison, including the termination of five senior researchers, says Ghilarducci, who anticipates more job losses at the other centers.
The math concept hidden in this tree art — geometric shapes known as fractals — is apparent in branching patterns in nature and may be key to humans’ ability to recognize such artwork as trees, according to Mitchell Newberry, a mathematical biologist at the University of New Mexico, and his colleague Jingyi Gao, a doctoral student at the University of Wisconsin.
Researchers from the University of Wisconsin-Madison and the University of Florida have discovered a treatment for placentas deficient in the growth hormone IGF-1 that may soon be going toward human clinical trials.
The manufacturing sector lost about 75,000 jobs as a direct result of the metals tariffs, according to a 2020 study by University of California, Davis economics professor Kadee Russ and University of Wisconsin-Madison assistant professor Lydia Cox for Econofact.
“It appears that there are forces intent on destroying our existing vaccine enterprise,” says Dr. Jonathan Temte, a professor of family medicine at the University of Wisconsin who studies vaccine hesitancy. “Defunding research on vaccine hesitancy is the latest example of this effort.”
Trey Wenger, a postdoc at the University of Wisconsin, is funded by the NSF and found himself financially stretched when the agency suddenly halted postdoc stipends, only to be restored by a court order. “I missed a paycheck when rent was due, and remain concerned that my paycheck could be turned off at any time,” wrote Wenger, whose work in astronomy helps us better understand how galaxies form and evolve.
UW-Madison professor Mariel Barnes conducted research into how and why the “manosphere” took political hold, and described her findings and its impacts on politics.
Donna Friedsam is a researcher emerita who has been studying health care policy and reform for decades at the University of Wisconsin-Madison. Friedsam told WPR’s “Wisconsin Today” that changes at the federal level could have significant ripple effects at home.
“Many people who are on Medicare, who are low-income, also duly rely on Medicaid to cover things that Medicare does not cover,” Friedsam said. “So, Medicaid is actually quite a wide-ranging program and reaches over a million Wisconsin residents who rely on it.”
The federal Department of Education’s Office of Civil Rights is investigating the University of Wisconsin-Madison for antisemitism, according to a press release issued Monday.
UW is one of 60 institutions that received letters “warning them of potential enforcement actions if they do not fulfill their obligations under Title VI of the Civil Rights Act to protect Jewish students on campus, including uninterrupted access to campus facilities and educational opportunities,” according to the release.
Four days before Rick Lindroth planned to leave Madison and fly to Argentina, he received an email saying his Fulbright award had been rescinded.
“That was a head spinner,” said Lindroth, a professor emeritus in the University of Wisconsin-Madison’s entomology department.
