Left unmanaged, deer can do a lot of damage in the UW Arboretum, which is why it hires sharpshooters who work after dark in winter to control the population.
“We do it to protect our plants, both in our gardens and in our natural areas,” said Michael Hansen, the Arboretum’s land care manager. “We also do it to maintain the health of the deer herd here.”

While there are still two months to go, it’s possible the race will stay muted because the stakes are different with no Supreme Court majority on the line, said Howard Schweber, a professor emeritus of political science and legal studies at the University of Wisconsin-Madison. Neither outcome will change liberal control of the court, though because the winner will replace retiring conservative Justice Rebecca Bradley, it could extend guaranteed liberal control until at least 2030.
Even after 20 years of performing kidney transplants, Dr. Nikole Neidlinger is still awestruck and humbled by the role she plays between the donors and recipients of these organs.
“The operation takes two to three hours,” said Neidlinger, director of Organ and Tissue Donation at the UW School of Medicine and Public Health. “When we attach a kidney and open it up to blood flow, it just starts functioning. I’ve seen it thousands of times now, but every time I’m like, ‘This is a miracle. This is amazing.’”
“There is no structural or blanket barrier to states bringing a criminal prosecution against federal officials,” says Harrison Stark, an attorney who works with the University of Wisconsin Law School’s State Democracy Research Initiative.
“If a state believes that a federal official has violated state criminal law,” Stark says, “the state has broad Investigatory Powers to collect evidence, to explore that criminal action, basically in the same way they would against anybody else.”
Jake Baggott, associate vice chancellor & executive director of University Health Services, said UW-Madison has directly notified around 4,000 people who may have been exposed. Speaking to reporters on Monday, Baggott said immunization data voluntarily reported by students shows many are already protected against the virus.
“We estimate, based on our own data, that about 95 percent of our campus is vaccinated against measles, which is a good place to be,” Baggott told reporters.
On a clear, calm winter night, Earth’s surface radiates infrared energy upward toward space. With the sun already down, there is no shortwave solar radiation (and only a very little infrared energy from the overlying atmosphere) directed downward toward the surface. Consequently, with each passing second, the surface emits more energy than it receives and the surface temperature drops.
As it turns out, expanding our vocabulary as adults doesn’t work as it did when we were children in school, said Kelly Wright, an assistant professor of language sciences at the University of Wisconsin-Madison. Young people can learn new words by doing reading exercises, acing vocabulary quizzes or listening to the grown-ups around them. But as we get older, we have to approach it differently.
“Our vocabulary grows to a certain point, but then there is something that turns off, in a similar way in which we grow from a child height to an adult height. Something kicks on in our femur, but we don’t end up 11 feet tall, and the same thing happens with our language system,” Prof. Wright said. “It doesn’t mean we can’t learn new things, but after you get past that point, you have to do it actively. Say ‘Hey mind! Wake up a little!’”
Minimum-wage hikes — depending on the size — can bring a mix of positive and negative economic consequences, according to Callie Freitag, assistant professor at the University of Wisconsin-Madison’s School of Social Work.
“The good thing is that earnings would go up for workers. Employers would raise wages and be able to pay workers more,” Freitag said. “But the money to pay workers more has to come from somewhere.”
“Because it’s not dependent on the wind or the sun, nuclear energy operates whenever we want it, pretty much,” said Paul Wilson, a nuclear engineering professor at the University of Wisconsin-Madison. “But even if we have to shut it down for refueling, that is very, very infrequent. Nuclear power plants today around the country typically operate for 18 months without shutting off.”
Leaders in Wisconsin agriculture are warning the state’s farmers to brace for another tough year for trade and market conditions.
The discussion at the annual Wisconsin Agricultural Outlook Forum at the University of Wisconsin-Madison focused both on the economic hardships weighing on farmers and what some producers are doing to try to get ahead.
Everyone knows it’s hard to get college students to do the reading—remember books? But the attention-span crisis is not limited to the written word.
Professors are now finding that they can’t even get film students—film students—to sit through movies. “I used to think, If homework is watching a movie, that is the best homework ever,” said Craig Erpelding, a film professor at the University of Wisconsin-Madison. “But students will not do it.”
Josiah Hanna, an assistant professor of computer science at the University of Wisconsin–Madison, said AI tools can be valuable educational resources but are often misunderstood or misused.
“AI is a dual-use technology,” Hanna said. “You can do some really cool things with it, but yet unfortunately has this really unpleasant use case that people have found and exploited in a really harmful way.”
Hanna said AI-generated images can be particularly damaging because people tend to trust what they see, even when content is fabricated.
The Trump endorsement cuts both ways, said Barry Burden, political science professor at the University of Wisconsin-Madison and director of the university’s Elections Research Center. On the plus side, Tiffany doesn’t have to worry about draining his resources on a primary fight, and can immediately direct his focus on the general election.
The downside? Tiffany is now tied to Trump, whose popularity is suffering, and the president’s party traditionally struggles in midterm elections, Burden noted.
“He’s going to have to negotiate expressing his own identity as a candidate versus trying to take advantage of the enthusiasm that Trump voters have (for Trump) in particular, and to get them out,” Burden said.
The University of Wisconsin–Madison and Immuto Scientific have teamed up to explore new therapeutic targets in colorectal cancer. According to the University of Wisconsin School of Medicine and Public Health, this collaboration aims to use Immuto’s AI-enabled platform to discover novel treatments for solid colorectal cancer tumors.
Dr. Dustin Deming, a professor of medicine at the University of Wisconsin School of Medicine and Public Health, leads the project. “Our collection of patient-derived colorectal cancer organoids enables exploration of tumor biology and therapeutic vulnerabilities in ways that traditional models cannot,” said Deming.
Within UW-Madison’s Department of Food Science, Professor Bradley Bolling has pioneered research of anthocyanins, natural pigments responsible for the vibrant hues in fruits like cranberries.
“We want to understand how the pigments in cranberry are stabilized,” Bolling said.
Bolling developed a patented process using lecithin, an emulsifier, to extract natural pigments from cranberries without using alcohol or acetone. This makes the process safer and more environmentally sustainable.
Dr. Anita Bhattacharyya, an associate professor of cell and regenerative biology in the school of medicine and public health at the University of Wisconsin-Madison, said she was hoping to apply for a future NIH grant to study human fetal tissue research and will now not be able to do so.
Bhattacharyya explained she currently uses human-induced pluripotent stem cells, which are reprogrammed cells that are similar to embryonic stem cells, in her work. However, the loss of NIH funding for human fetal tissue research could affect future work.
“My reaction was, ‘How are we going to do some of our research if we can no longer use human fetal tissue?'” she recalled to ABC News. “In particular, my lab studies Down syndrome and so we know that in Down syndrome, the brain develops differently to lead to the intellectual disability that people with Down syndrome have.”
Partisan media and shoddy reporting have a long history in the U.S., but one parallel stands out: the era of the so-called yellow press, which got its name from a cartoon strip published in papers featuring a child in a yellow shirt.
“It was a moment before professional news values had really set in, before there were professional codes of ethics,” says Lucas Graves, distinguished researcher at Universidad Carlos III de Madrid and a professor in the School of Journalism and Mass Communication at the University of Wisconsin–Madison. The biggest newspapers, like the New York World and New York Journal, would run serious, reported news stories. But they “would also run stories to try to generate outrage and almost invent scandals in order to sell more newspapers,” Graves says.
“I think that there was absolutely a market decision behind selecting Bad Bunny,” says Jorell Meléndez-Badillo, a professor of Latin American studies at the University of Wisconsin who has collaborated with Bad Bunny to incorporate Puerto Rican history into his shows and music videos. “The NFL wants to expand internationally, so they are looking to target a broader market beyond the United States. He has a huge following in the United States, but this stage will also be amplified internationally by having someone like him.”
Some analysis will have to wait until the new images can be processed, but the researchers are already able to decode text from many of the raw data. “It’s one of the rare examples in research where you know very quickly that you have gotten good results,” says Uwe Bergmann, a physics professor at the University of Wisconsin–Madison, who is overseeing the experiment’s x-ray scanning.
Botulism spores are common in the environment and can be found in most foods at very low levels, said Kristin Schill, a botulism expert at the University of Wisconsin-Madison.
Healthy adults consume Clostridium botulinum spores every day without becoming sick. But babies have immature guts that may not be able to prevent the spores from germinating and growing. Once they do, the spores produce a toxin that can cause paralysis and death.
Spores can be found everywhere, including in milk, though typically at low levels, Schill said. Pasteurization doesn’t kill the germs. They can be present in the processing environment, too.
“Cracks can happen at anything below the freezing temperature, so 32 degrees Fahrenheit or zero degrees Celsius,” said Scott Bowe, a professor and wood products specialist at the University of Wisconsin-Madison.
Bowe clarified that the noises, known as frost cracks, are not caused by expanding sap.
“Some people have explained it as the sap is expanding like ice and causing the crack that actually is not what’s happening. It’s actually the drying of the wood that causes the crack to happen,” said Bowe.
Professor Laura Albert, a Vilas Distinguished Achievement Professor of industrial and systems engineering at the University of Wisconsin–Madison, has studied EMS deployment and logistics for decades. She said many departments are being asked to stretch limited resources further than ever before.
“So often these public service agencies like EMS departments are asked to do more and more with less,” Albert said. “You can do that up to a point, but this is kind of hitting a crisis point.”
“In certain neighborhoods, perhaps in Atlanta or Philadelphia or Chicago, maybe you’re reaching a much higher market saturation point,” said Kurt Paulsen, a University of Wisconsin-Madison professor who studies urban planning. “I’ve not seen any evidence of any even modest market penetration of that product in Dane County and Madison.”
John Dunne, a Buddhist philosophy scholar at the University of Wisconsin–Madison, offers a helpful explanation if you’ve ever wondered why everyone seems to talk about mindfulness in a different way. Dunne says mindfulness isn’t one single thing, but a “family” of related practices shaped by different traditions, purposes and cultural backgrounds.
A growing number of states, including Illinois, prohibit openly carrying “long guns” — meaning rifles and shotguns — at protests. Those rules aim to prevent armed confrontations between protesters, counterprotesters and law enforcement, said University of Wisconsin-Madison law professor John Gross. “What (law enforcement) don’t want,” he said, “is a situation where you have two armed groups facing off against one another with the police in between them.”
Andrew Reschovsky, professor emeritus at the University of Wisconsin-Madison’s La Follette School of Public Affairs, said Wisconsin has a particularly complex system of school funding.
“The legislature said we are not going to increase state aid at all, not by one penny of general aid,” Reschovsky said.

Bryna Godar, a staff attorney at the State Democracy Research Initiative at the University of Wisconsin Law School, said Madison’s argument is “conflating two different things.”
“The Legislature has, in these absentee voting statutes, made clear that it considers absentee voting to be a privilege, in that absentee voting as a method is not constitutionally required, and that the Legislature can impose some additional procedures on absentee voting that it maybe couldn’t impose on in-person voting,” said Godar. “That privileged language does not mean that when you vote absentee, you don’t have a right to have your vote counted.”
An assistant professor in the University of Wisconsin-Madison’s Department of Animal and Dairy Sciences wants to improve sheep’s quality of life.
Sarah Adcock focuses her research on the welfare of farm animals, including specializing in the docking of lamb tails, a routine procedure on farms that can lead to acute and sometimes even chronic pain for the animal.
Statewide, school enrollment data tells a similar story: throughout the 2000s and 2010s, enrollment in suburban school districts increased, while rural school enrollment continually declined, according to Sarah Kemp, a researcher at the University of Wisconsin-Madison’s Applied Population Lab. Urban school districts, including Milwaukee, saw relatively steady enrollment through the 2010s, but the pandemic brought a sharp decline in student enrollment in most Wisconsin cities.
“There’s maybe not housing available for those young families to move into, or maybe the opportunities aren’t there for young families to find employment, and that may then show up in the school districts with declining enrollment,” Kemp said.
“We don’t have the fountain of youth— nobody ever found it,” said Dudley Lamming, co-director of the Wisconsin Nathan Shock Center (WiNSC) and professor of medicine at the University of Wisconsin-Madison, “but can we find ways [to] get to the end of our lives, still fit and functional?”
UW-Madison Athletic Director Chris McIntosh considers impacts of a decline in Wisconsin Badgers football season ticket sales for the 2025 season and the significance of that revenue to the university.
UW-Madison researchers argue undisclosed organizations targeted users based on race and location to discourage them from voting.
Young Mie Kim is a coauthor of the report and a media professor at UW-Madison. Kim was one of the first independent researchers to discover Russian interference in the 2016 election.
“It was just difficult just to surgically target these people, until now,” Kim said. “But with (today’s) data-driven, micro-targeted, algorithm-based information environment, it’s much more effective.”
Wisconsin legislators haven’t directed a ton of their attention to higher education issues during the current legislative session, lobbyist Jack O’Meara said.
“It just seems generally that it’s not at the top of the list of items that are being discussed … so I don’t see a whole lot of bills moving,” said O’Meara, who advocates on behalf of faculty at the University of Wisconsin-Madison through an organization called PROFS.
“I am just a lot more concerned about how we design the digital landscape for kids than I am about whether we allow kids to use screens or not,” said Heather Kirkorian, an early childhood development researcher at the University of Wisconsin-Madison. “I haven’t seen concrete evidence that convinces me that screen use itself is creating problematic behavior.”
Campus and community leaders are congratulating Chancellor Jennifer Mnookin as she prepares to step down as leader of the University of Wisconsin-Madison.
Some people refer to the muriqui as “the hippie monkey” – a slightly sensationalising term that nonetheless captures their “relaxed” lifestyle, says Karen Strier, a primatologist at the University of Wisconsin-Madison in the US, who has studied muriquis for decades. She mentions, for example, that the monkeys are, sexually speaking, very laid back. “Females mate with multiple males in close succession,” she says.
From 2020 to 2024, preliminary figures show the state has seen reports of 495 manure spills and incidents, according to Kevin Erb. He’s the manager of the Conservation Professional Training Program at the University of Wisconsin-Madison Division of Extension, which trains manure applicators. Erb did not have figures on the amount of manure spilled, saying releases are often estimated.
Through the Senior Guest Auditor Program, Wisconsin residents aged 60 and older take UW-Madison courses free of charge alongside students less than half their age. This fall, the program reached a record enrollment of more than 1,000 auditors, double the number enrolled a decade ago, according to program administrator Anne Niendorf. The program places older adults alongside traditional undergraduates in lecture halls across campus, creating multigenerational classrooms.
The Cinematheque, the University of Wisconsin-Madison’s dedicated screening facility for international cinema history and fine films, returns this week for its 2026 slate — filling a niche since the 1990s by promoting movies audiences in Madison might otherwise miss.
“Sometimes good movies are brought to us through a proposed partnership with another campus department or community organization/concern,” said Jim Healy, Director of Programming at the Cinematheque. “Sometimes some movies are more relevant, like our screening of ‘Slap Shot’ last January in honor of Paul Newman’s centennial.”
Demographer David Egan-Robertson kicked things off in an interview with “Wisconsin Today,” looking at the big trends in the state’s population. Egan-Robertson has followed this story for years in his work with the Applied Population Laboratory at the University of Wisconsin-Madison.
Last year, just as she was finishing a teacher residency program through the University of Wisconsin-Madison, federal funding for the project was cut by the Trump administration.
“So we were in the spring semester and we were all like, are we going to be able to continue?” Lind said. “Are we going to still be able to get our teaching license? Are we going to have to pay this back?”
Consolidation continues to be the biggest factor shaping the number of farms in the state, according to Steven Deller, agricultural and applied economics professor at the University of Wisconsin-Madison.
“If you’re in your mid-60s, it just doesn’t make sense to be operating a dairy farm with 150 cows,” he said. “That’s demanding work, that’s really hard labor, and you hit a certain point where you just say, ‘I can’t do this anymore.’”
University of Wisconsin-Madison researchers are studying whether a drug used for organ transplant patients could slow aging in humans.
Some compelling evidence in recent decades shows rapamycin — also known as sirolimus — can increase the quality and quantity of life in animals, said Adam Konopka, a UW-Madison assistant professor of geriatrics and gerontology.
“This got people really excited that maybe this drug could be used to improve human healthy longevity,” he said.
A few years ago, a small baker from the West Coast had a problem. A day or so after baking chocolate chip cookies, the chocolate chips would develop an unpleasant white haze. Confused, she reached out to Richard Hartel, a professor of food science at the University of Wisconsin.
Hartel studies foods like chocolate and ice cream, and he gets questions like this all the time. So what was going on with those chocolate chips?
The bill is “is a Band-Aid to stop the bleeding,” said Ryan Poe-Gavlinski, director of UW-Madison’s Restraining Order and Survivor Advocacy Clinic. She said it could fill a critical funding gap until lawmakers figure out a long-term solution.
But the number of victims in need of services is continually on the rise. Wisconsin broke records for domestic violence-related deaths in 2024.
“We’re going to always have victims who need assistance, and there’s just not enough people to help the victims,” Poe-Gavlinski said.
Political experts have said it’s possible, but not likely, congressional candidates will run on new maps this year.
“I think it’s not impossible, but a court would really have to give dedicated attention to the case and prioritize it over others,” Barry Burden, political science professor at the University of Wisconsin-Madison and director of the university’s Elections Research Center, told the Milwaukee Journal Sentinel last month. “There would just have to be a kind of rapid-fire set of events to get through all those steps in time for the 2026 cycle.”
Still, University of Wisconsin Law School professor and co-director of the State Democracy Research Initiative Rob Yablon noted, “it’s conceivable” the plaintiffs in the case brought by Elias Law Group will push for a speedy process. The plaintiffs’ attorney, Julie Zuckerbrod, argued during a scheduling conference that the case could in fact be decided in time for the 2026 election.
“They try to make you scared by making you feel like you’re the victim, and they’re calling to help,” said Rick Wash, professor of information science at the University of Wisconsin, in a phone interview. Wash is a computer scientist who researched the possibility of electronic breaches two decades ago. He then began mixing his vast technical knowledge to focus on the personal side of the scam.
“I began to realize the human factor was often the most critical factor of computer scams,” Wash said.
“Oh, no,” lamented Sarah, “Is it going to happen again?” She was responding to the possibility that her partner, Joshua, would lose his temper once again, which was a frequent occurrence. She did not trust him, and the result was anxiety, leading to sleeplessness, worry, and irritability. Research reviewed by Tomlinson and Mayer (2009) supports the view that mistrust can be accompanied by anger and fear. Joshua’s temper and Sarah’s response of anxiety were affecting their relationship.

Research by Ben Fisher, a University of Wisconsin-Madison associate professor who reviewed 32 evaluations of school-based police programs, found some students say they feel safer with police in their buildings while others say a police presence makes students more attuned to a sense of danger and some see police as a source of violence.
Yi Fuxian, an obstetrician at the University of Wisconsin-Madison, an expert on Chinese demographics, said during an interview with the Financial Times: “The decline in China’s fertility is inevitable, like a giant rock rolling down a hill. China’s one-child policy accelerated the process. It will be very difficult to move it back up hill.”
Last year, around 300,000 Wisconsin residents qualified for and used the enhanced subsidies, said Dan Sacks, associate professor of risk and insurance with the Wisconsin School of Business at the University of Wisconsin-Madison.
“It’s just going to be a lot harder for many people to get coverage,” he said.
“It is exciting to bring back something so impactful and reimagine it for a new audience,” said König-Tarasevich, a professor of flute at the University of Wisconsin-Madison.
According to experts, the average person who works for tips could save up to $1,300 on their taxes.
“But in practice, $25,000 in tips is a lot of tips to be receiving, and so very few people are going to find themselves in that situation,” said Ross Milton, an associate professor at the La Follette School of Public Affairs at the University of Wisconsin–Madison. “Some people who even who receive tips, might not really be saving anything because they may not really have too many people who receive tips, actually don’t have enough income to pay a significant amount of income taxes.”
Avtar Roopra’s research has effectively stalled since President Donald Trump started his second term and upended the federal research funding landscape. Agencies have cut projects, delayed grant reviews, fired thousands of federal employees who offer guidance to researchers and reduced the number of new projects getting funding.
“This is like the Holy Grail of epilepsy, what we’ve been looking for for hundreds of years,” Roopra said. “All of it is on hold. It’s extremely frustrating.”
“The court is very clear that the Constitution gives no authority to the president to do any of these things, and that federal law doesn’t either,” Derek Clinger, a senior staff attorney with the University of Wisconsin Law School’s State Democracy Research Initiative, told Votebeat.
Experiments by researchers at the University of Wisconsin-Madison show that viruses and bacteria behave differently in near-weightless conditions. In space, they develop genetic changes not typically seen on Earth.
Lead study author Dr. Phil Huss, a researcher at the University of Wisconsin–Madison, noted that interactions between viruses that infect bacteria — known as phages — and their hosts play an “integral” role in how microbial ecosystems function, per the SWSN report.
States have broad power to regulate within their borders unless the U.S. Constitution bars it, but many of these laws raise novel issues that courts will have to sort out, said Harrison Stark, senior counsel with the State Democracy Research Initiative at the University of Wisconsin Law School.
“There’s not a super clear, concrete legal answer to a lot of these questions,” he said. “It’s almost guaranteed there will be federal litigation over a lot of these policies.”
