“Thinking about how the central part of the country or even the Gulf Coast states get cold air isn’t just thinking about what’s happening locally,” says Andrea Lopez Lang, an atmospheric scientist at the University of Wisconsin–Madison. “You have to really zoom out and take a big-picture perspective.”
A 2023 UW-Madison School for Workers survey found that over 10,000 undocumented workers perform around 70% of the labor on Wisconsin’s dairy farms. “Without them, the whole dairy industry would collapse overnight,” the researchers concluded.
With the discovery of a new dinosaur species, researchers at the University of Wisconsin–Madison have challenged a long-held belief about where dinosaurs originated and how the ancient reptiles spread throughout the planet.
Freshwater organisms are sensitive to salt, so when too much road salt gets flushed into waterways it has lethal consequences, said Jessica Hua, an associate professor at UW-Madison who studies human influence on aquatic ecosystems. Even small amounts can build up over time.
“It was basically the size of a chicken but with a really long tail,” says lead author Dave Lovelace, a vertebrate paleontologist from the University of Wisconsin Geology Museum. “We think of dinosaurs as these giant behemoths, but they didn’t start out that way.”
While ornithologists, citizen scientists, and birders alike are familiar with this large repertoire, some of the environmental conditions that contribute to these sounds are less understood. To help, a team from the University of Wisconsin-Madison recently used over 100,000 audio recordings from around the world to study some of the factors that influence bird sounds. They found some patterns of how habitat, latitude, beak size, body size, and the landscapes can influence birds to create certain noises and at what frequencies. The findings are detailed in a study recently published in the journal Proceedings of the Royal Society B.
Researchers from the University of Colorado at Boulder and the University of Wisconsin-Madison looked at insurance contracts, focusing on nearly 5,000 policyholders who filed claims after the fire.
They found that 74% were underinsured, meaning they weren’t fully covered for total losses. And of that share, 36% of them were severely underinsured, meaning they were covered for less than 75% of their home’s replacement cost.
Analysing the data up to 2004, Prof. Jane Allyn Piliavin and her colleague, Erica Siegl, at the University of Wisconsin-Madison found that people who were regularly involved in these activities tended to report better physical and mental health. This might be expected: if you are feeling well, you are more likely to have the capacity to help others.
The museum field crew’s find is not just a new species — it’s the oldest dinosaur ever discovered in the northern hemisphere.
Tom Friedrich, professor of virology at the University of Wisconsin-Madison’s School of Veterinary Medicine, said more details are needed to understand what led to the patient’s death. But he pointed out that other countries have already seen deaths caused by similar H5N1 viruses, especially in people who are sick enough to be hospitalized.
“There’s over 50 percent case fatality when people have these severe infections,” Friedrich said. “So it’s not unheard of in other parts of the world, even though this is the first time it’s happened in the United States.”
University of Wisconsin-Madison researchers recently made what they call surprising discoveries about how childhood trauma affects mental health in adolescence, thanks to a national trove of childhood health data.
“Normally, strong winds this time of the year simply present a risk for wind damage,” said Jason Otkin, an associate research professor at the University of Wisconsin-Madison, in an email Tuesday. “But this time, they could also lead to explosive fire growth due to the very dry vegetation.”
A recent paper from researchers at the University of Utah and the University of Wisconsin-Madison explored the aftermath of the deportation of more than 300,000 undocumented immigrants nationwide from 2008 to 2013. In the places where deportations happened, the study found, homebuilding contracted because the local construction workforce shrank and home prices rose. The researchers discovered that other construction workers lost work too because homebuilders cut back on new developments.
Yohishiro Kawaoka, a virologist at the University of Wisconsin-Madison and the University of Tokyo, said the the death “highlights the need for vigilance in avoiding contact with the virus wherever possible.”
At the same time, however, Kawaoka said it was “important to note that the individual was over 65 and had underlying health conditions, which may have contributed to the severity of the illness.”
“Although e-cigarettes have been on the market for over 15 years, we really don’t know anything about their long-term health effects,” said Dr. James Stein, professor of medicine and director of Preventive Cardiology at UW Health.
UW-Madison researchers are looking for 600 people to participate in a study about the long-term effects of vaping on heart and lung health
A lead researcher on the study, Sarah Halpern-Meekin, who’s a professor in the School of Human Ecology and director of the Institute for Research on Poverty at the University of Wisconsin-Madison, said at the end of the day, people want to feel like the work they’re doing is meaningful.

UW-Madison researchers evaluating the potential of psychedelic drugs to ease mental health conditions plan to launch a new kind of study: examining the potential for ketamine to treat teens with post-traumatic stress disorder.
Dorota Grejner-Brzezinska wasn’t looking for a new job when a search firm asked if she’d be interested in leading research at the University of Wisconsin-Madison. Grejner-Brzezinska had spent about 28 years at Ohio State University, studying GPS uses and directing the school’s Office of Knowledge Enterprise, among other roles. She was tempted, though, by UW-Madison’s national reputation as a research powerhouse.
The nearly 150,000-square-foot Element Labs opened at University Research Park in March 2024, with space for up to 20 bioscience companies. A similar-size project, called Velocity Station, is slated to replace the former Clock Tower office park at 6411 Odana Road, but no timeline has been announced.
The Wisconsin Alumni Research Foundation, known for helping UW-Madison commercialize discoveries such as vitamin D enrichment, a blood thinning drug and stem cells, may seem like a solid presence on campus whose existence was never in doubt.
But WARF, the nation’s first university technology transfer office, had to fight for survival from its founding in 1925 until at least 1980, when the federal Bayh-Dole Act said universities could retain patent rights on federally funded research.
Pallavi Tiwari, a radiology and biomedical engineering professor at the University of Wisconsin-Madison, has spent the last 18 years developing artificial intelligence models to help study cancer.
Much of that work includes using machine learning to find ways to help predict cancer diagnosis, outcomes and drug responses, she said.
A study from the University of Wisconsin actually shows that wood can kill bacteria in as quick as three minutes, while plastic cutting boards can allow bacteria to grow many days without proper care.
The mapping was done using magnetotellurics that measure the electrical conductivity of what lies below the Earth’s surface. Melted rock, magma, is extremely good at conducting electricity, so it makes precise mapping of areas where magma is stored possible. The testing was conducted over several months by scientists from the USGS, Oregon State University and the University of Wisconsin-Madison.
Keith Poulsen’s jaw dropped when farmers showed him images on their cellphones at the World Dairy Expo in Wisconsin in October. A livestock veterinarian at the University of Wisconsin, Poulsen had seen sick cows before, with their noses dripping and udders slack.
While non-gun owners might think that asking about guns feels overbearing, research, perhaps surprisingly, shows that gun owners welcome the conversation, says Nick Buttrick, a psychologist who studies the symbolism of gun ownership at the University of Wisconsin–Madison. People in focus groups who own guns say that talking about gun safety is actually really important to them. “The anticipated friction stops people from having the conversation,” Buttrick says, “but when they actually have it, they’re received with a lot more positivity than they might have imagined.”
Researchers at the University of Wisconsin-Madison have collected brain scans in a first-of-its kind study on Alzheimer’s disease.
“Speedcubing offers a unique combination of cognitive challenge, [alongside] social connection, and personal achievement that contributes to happiness”, says Polina Beloborodova, research associate at the University of Wisconsin-Madison’s Centre for Healthy Minds.
It might seem remarkable that she recognized the find for what it was: Dugout canoes, the world’s oldest boat type found to date, are simply hollowed-out logs. In 2018, however, Thomsen had teamed up with Sissel Schroeder, an archaeologist with the University of Wisconsin-Madison, to help an undergraduate student catalog Wisconsin’s extant dugout canoes. When the project began, historians believed 11 existed in collections across the state. Less than a year later, after scouring private collections, supper clubs, local museums and more, the team had counted 34.
“We need a very big target, such as a billion tons of material, to have a fighting chance to — once in a while — catch some of them,” said Albrecht Karle, a professor of physics at the University of Wisconsin-Madison.
There are a handful of variables and factors that shape the financial losses of a dairy hit with an outbreak. Luckily, agriculture economist Charles Nicholson at the University of Wisconsin-Madison and some colleagues created a calculator to estimate this financial impact of a bird flu outbreak. Based on Nicholson’s estimates for California, a typical farm of 1500 cattle will lose $120,000 annually. For context, this is about $10,000 more than the median household income of a dairy farmer.
Cosmic radiation poses a perennial challenge for astronaut safety, says Hannah Carey, an emeritus professor of biology at the University of Wisconsin-Madison, where she studied hibernators as a model for stress and trauma protection. Carey has been part of meetings and conferences with ESA and NASA scientists discussing hibernation science. In these dialogues, she recalls that radiation protection has been of particular interest.
David Drake leads the Urban Canid Project at the University of Wisconsin-Madison. Since 2014, researchers with the project have studied where coyotes and red foxes live in the Madison area, when they are active and how they interact with each other, in addition to humans and pets. University students help Drake set up traps around the city from November to March, so they can put radio collars on animals and track them.
“We’ve gotten some really good data,” said Drake, a professor and Extension wildlife specialist at UW-Madison’s Department of Forest and Wildlife Ecology.

Can large solar farms and cultivated crops coexist? Our guests says “yes.” Agrivoltaics is the convergence of agriculture and solar farms, which is the area of study of UW-Madison hydrologist and professor Steven Loheide and professor of atmospheric and oceanic sciences Ankur Desai.
What these idealists forget is that while people used to live on more natural products, they were also pretty unhealthy. According to John A. Lucey, PhD, a professor of food science at the University of Wisconsin–Madison and director of the Wisconsin Center for Dairy Research, it’s estimated that in 1938, pre-pasteurisation, milk-borne outbreaks constituted 25% of all disease outbreaks (related to food and water) in the United States. Now, they make up fewer than 1%.
Christian Franck, a mechanical engineering professor at the University of Wisconsin-Madison, leads PANTHER, an multi-institution research hub based at UW-Madison, focused on understanding, detecting and preventing traumatic brain injuries. The hub brings together experts from different disciplines.
PANTHER has received over $50 million from the U.S. Office of Naval Research since 2017, including an additional $10 million recently to investigate how pulsed microwaves might injure the brain.
“Most of the increase in recent decades is in relatively mildly affected children and adults, so maybe in the past we wouldn’t have called it autism,” explained Maureen Durkin, professor of population health sciences at the University of Wisconsin-Madison.
“There’s very clear evidence that screening prevents vision loss,” says Roomasa Channa, a retina specialist at the University of Wisconsin-Madison in the US.
Scientists, including Charles Raison of the University of Wisconsin–Madison and Andrew Miller of Emory University, have meanwhile identified mechanisms by which inflammation can cause depression. Inflammatory cytokines circulating in the blood can weaken or even breach the protective barrier between blood vessels and the brain. Once inside the brain, they trigger its immune cells, called microglia, to produce further inflammatory agents.
The lifespan of a chicken varies. The average lifespan of a hen is between six and eight years, according to the University of Wisconsin-Madison. During three to four of those years, hens will produce eggs.
“This confirms our view of how the Earth cooled and became habitable. This may also help us understand how other habitable planets would form,” Professor John Valley, a geochemist at the University of Wisconsin-Madison, said in a statement made in 2014.
Dr. Tiffany Glazer spoke with WMTV Friday about the risks present for pregnant surgeons. Dr. Glazer is an ear, nose and throat surgeon at UW-Health, and led a review of this literature published in the journal of American Medical Association.
“These are folks who can ill afford to spend that kind of money on what is really not a necessary thing,” said Manny Teodoro, a researcher at the University of Wisconsin-Madison who studied the water vending machine industry in a 2022 book, “The Profits of Distrust.” “Money spent on (vended) water is money that’s not spent on healthier food, on perhaps needed medicine and healthcare.”
The two-lined chestnut borer is now “the most important insect cause of oak mortality,” especially for stressed, injured and weakened trees, according to Wisconsin Horticulture at the University of Wisconsin-Madison.
With more people than ever taking part, the annual Audubon event is a growing force for science and nature conservation.
This trove of information has helped usher in entire new areas of research, like climate change ecology, says Benjamin Zuckerberg, a researcher at the University of Wisconsin–Madison. His work in the field utilizes large community science datasets to explore how birds, including common winter denizens such as Red-bellied Woodpeckers, Purple Finches, and Carolina Wrens, are shifting their movements in response to changes in temperatures. The data enable scientists to find answers to questions at an “unprecedented” level, Zuckerberg says.
In the only social science work on the issue in Wisconsin, a 2023 study by the University of Wisconsin Survey Center found 17.6% of its panel of state residents supported crane hunting while 47.6% opposed it and 35% were neutral.
McAfee’s products have been linked to several outbreaks of E. coli, salmonella and campylobacter, according to the University of Wisconsin Center for Dairy Research. Even with on-farm testing, raw milk isn’t safe for public consumption, said Alex O’Brien, safety and quality coordinator at the Center, which is on the UW-Madison campus.
“The more people who consume it,” he said, “the higher the probability someone’s going to become ill.”
“Cheesemaking is a process of concentrating the solids originally present in milk,” Ben Ullerup Mathers, a research cheesemaker at the University of Wisconsin-Madison’s Center for Dairy Research, tells SELF. “Since protein is one of the main constituents of milk solids, the further you concentrate those solids, the more protein is in the final cheese. Since hard cheeses are the lowest-moisture cheeses, they will also be the higher-protein cheeses.”
This discovery began incidentally in 2014, when David Lovelace, a researcher at the University of Wisconsin-Madison, picked up a soccer ball-sized rock on the way back to his car after a day of picking through the Popo Agie formation near Dubois, Wyoming.
If “they receive what they have asked for, they’re still going to be quite happy because they’re getting something that they want,” said Evan Polman, an associate professor of marketing at the Wisconsin School of Business at the University of Wisconsin at Madison.
In the parts of the city inhabited by Africans during the period of segregation, levels of fine particulates known as PM2.5 are high enough to reduce life expectancy more than tobacco use or HIV infection, said the study’s lead author, air quality scientist Dorothy Lsoto of the University of Wisconsin–Madison.
“When you look at the air quality in these different places, it’s striking,” Lsoto said.

On a recent Tuesday at the University of Wisconsin at Madison, sample number 435 lies supine on a lab table where it surrenders to a gauntlet of measurements.
Brandon Prochaska slides a thermometer into the pizza’s abdomen, and the digits tick upward to 205 degrees Fahrenheit. He and a group of other trained professionals jot the number down.
In 2013, researchers at University of Wisconsin put people in MRI machines and threatened to shock them at random. The researchers measured fear activity in each person’s brain. And they found something incredible in the third group. Participants’ brains were much less active. They could literally outsource their fear to their loved ones.
Fusion energy’s potential to produce abundant, clean energy to fuel industry and power advancements in artificial intelligence is no longer a matter of if, but when.
In October, the University of Wisconsin-Madison’s Collaborative for Reproductive Equity, known as CORE, released a study on the demand for abortion medications. The report examined how many people in Wisconsin ordered pills from out-of-state providers. The data was collected by the organization #WeCount, a national effort to track how many clinician-provided abortions are performed each month.
Approached by the U.S. Army and Air Force to detect chemical threats, toxins, and other environmental hazards for soldiers, UW-Madison biochemistry professor Vatsan Raman “wanted to take proteins that nature normally makes and then redesign these proteins to get them to sense molecules that we care about.”
