The new numbers are still way below the average from the first 10 years of monitoring (about 21 acres) and what scientists consider sustainable (about 15 acres). But they still amount to good news, said Karen Oberhauser, a professor emeritus at the University of Wisconsin-Madison, and one of the nation’s leading monarch experts.
“We are in a period of relative stability where the population has stopped declining,” Oberhauser, who was not involved in the new WWF Mexico report, told me.
Researchers from several prominent universities examined the self-reported sleep habits of nearly 130,000 teens. They found that the number of teens getting insufficient sleep, defined as seven hours or less a night, rose from 69% in 2007 to 78% in 2023, the most recent year for which data was available.
“We know that sleep plays a really critical role in adolescent brain development,” said Tanner Bommersbach, a child and adolescent psychiatrist and assistant professor of psychiatry at the University of Wisconsin-Madison and one of the authors of the study. “So when large numbers of teens aren’t getting enough sleep, it really raises concerns about the downstream effects that that could be having on their mental health, on their academic performance, on their engagement and risk behaviors.”
According to Betül Kaçar, an astrobiologist at the University of Wisconsin-Madison, organisms developing the ability to “eat” radiation isn’t out of the realm of possibility—in fact, it has happened already on Earth.
“Life found a way to eat pretty much anything it can on this planet. It’s quite remarkable,” she says. “If you think about it, the fact that life can capture photons [or particles of light] is ‘eating radiation.’ … For many microbes, the photons are great resources of energy. So phototrophs are an example of radiation-eating organisms on this planet.” Plants are well-known phototrophs, but sea slugs are unexpected ones, making their ability to gain fuel from radiation just as remarkable as that of the Astrophage microbes.
The importance of relationships cannot be overstated, said Robert McGrath, a University of Wisconsin-Madison psychologist who gives public talks on how to live with vitality and resilience. He pointed to one of the longest-running studies on well-being, where Harvard University scientists followed the same group of men since 1938. The study revealed a simple yet profound conclusion: Good relationships lead to health and happiness.
Share experiences with others, even if it’s a solitary activity, McGrath recommended. He teaches a meditation class, for example, which is not exactly made for sparking conversation. But he sees strangers connect before and after class.
“Any form of connection is going to boost one’s mood,” he said. “Make that effort. Get out and connect.”
Madison-based biotech leader Exact Sciences has gifted UW-Madison’s foundation $2.5 million to improve early cancer detection discoveries through research.
The Wisconsin Foundation and Alumni Association’s new grant will establish the James Dahlberg Fund for Cancer Detection and Clinical Integration, named after UW-Madison professor emeritus James Dahlberg, to support university researchers and clinical trials at UW Health focused on detecting and preventing cancer.
They’re tiny organisms, invisible to the human eye, and they’re inside you right now. This isn’t a description of a sci-fi monster but it is one of bacteria — single-celled organisms that can cause illness and death but might also help us to sleep better or find the motivation to exercise.
In short, we depend on bacteria, said Timothy Paustian, a professor in the Department of Bacteriology at the University of Wisconsin-Madison.
“They’re really important for your health. You have a whole group of organisms that live inside you,” Paustian said.
Wisconsin currently has 370 active or pending concentrated animal feeding operations (CAFO) permits, most of which are dairy farms with about 700 or more cattle. Wisconsin dairy farms produce roughly 12 billion pounds of manure annually, according to the University of Wisconsin-Madison Extension office.
Once the viruses adapted to microgravity by subtly shape-shifting, though, they became even more effective bacteria killers. “A simple microgravity experiment exposes these mutations that have much higher efficacy against pathogens,” says senior study author Srivatsan Raman, a chemical and biological engineer at the University of Wisconsin–Madison.
A roadside sign that welcomes drivers to Burlington notes that the Wisconsin city was the boyhood home of Tony Romo, a former Dallas Cowboys quarterback and current television commentator.
There is no mention of Frederic Edward Mohs, born there in 1910, the visionary physician who invented a skin-cancer procedure bearing his name that has benefited millions.
West Bend has been working with the University of Wisconsin-Madison Applied Population Lab, which found the district’s enrollment changes are primarily driven by demographic trends, particularly declining birth rates not made up for by new arrivals. The report also notes that kindergarten classes have not replaced the number of graduating seniors in recent years.
The Department of Forest and Wildlife Ecology at the University of Wisconsin held a seminar March 11. It focused on the relationship between the effects of fires and habitat fragmentation on population dynamics of narrow-leaved purple coneflower, Echinacea angustifolia, on the ever fragmenting prairies of western Minnesota. The seminar was hosted by research ecologist at the UW Arboretum Jared Beck.
After taking community and tribal input, the Manoomin Team aimed to address mixed concerns regarding the state of the restored wild rice — some members of the community feared the rice because of the water it was living in, while others thought that if manoomin was present and growing, it must be healthy, according to Ojibway.
The Hua Lab at UW, led by associate professor within the Department of Forest and Wildlife Ecology Jessica Hua, has been a key partner in testing samples for heavy metals and PFAS.
“What we know so far … is that wild rice plants, the way that they grow, the way they make seed, is pretty protective of people’s health,” Erickson said. “I think we feel pretty good about people eating rice in the estuary and we can share that with people.”
Phonics—how letters represent sounds—is critical to reading. But once students have mastered its rules, the bulk of their time should be spent working with authentic texts, experts say.
“There are indications, circumstantial indications, that what’s happening is a lot of overteaching,” said Mark Seidenberg, an emeritus professor of psychology at the University of Wisconsin-Madison, at the March 2 annual symposium of the AIM Institute for Learning and Research, a literacy professional development group.
Entrepreneurs launching startups through UW-Madison and the Wisconsin Alumni Research Foundation will soon have a larger presence on the West Coast.
The university and WARF, the campus’ nonprofit patent licensing arm, are partnering with seven other schools to open a two-year pilot workspace in San Francisco that university-founded startups and teams traveling to the Bay Area can use for work and to meet with investors.
Scientists at the Wisconsin Crop Innovation Center are pioneering the future of hemp farming. Researchers at UW-Madison have received deregulation from the U.S. Department of Agriculture for 3 gene-edited hemp lines, allowing field cultivation without special permits.
Senior research scientist Mike Petersen explained they use a tool called CRISPR to gently edit the plant’s DNA, giving it traits like no THC or resistance to disease. Back in November 2025, the first line approved was Badger G, high in CBG, and known to reduce inflammation and other pharmaceutical benefits.
“When the neutrino interacts in the ice, it shatters an atom and the splinters from that direction are a lot of energetic subatomic particles,” UW-Madison professor of physics and astronomy — and frequent IceCube collaborator — Justin Vandenbroucke said. “A fraction of those have electric charge, and they make a flash of blue light.”
First, we learn about the impacts of rising gas prices in Wisconsin. Then, we talk to a researcher and an advocate about Wisconsin’s FoodShare program and new work requirements.
The Trump administration disrupted university research last year by canceling grants, delaying new awards and seeking other policy changes that put millions of dollars in jeopardy both in and beyond Wisconsin.
“There continues to be great volatility and uncertainty around federal funding, which is our largest single source of external revenue,” Chancellor Jennifer Mnookin said at a campus meeting last month.
Outgoing Chancellor Jennifer Mnookin praised the University of Wisconsin-Madison’s artificial intelligence initiatives in her address to the Board of Regents last month, including one new tool researchers have been using to partner with industry partners and collaborators.
“It’s not labor digging if it’s mutually beneficial: He agrees to provide financial resources, and she agrees to make the home a haven,” said Allison Daminger, an assistant professor of sociology at the University of Wisconsin–Madison and the author of “What’s on Her Mind: The Mental Workload of Family Life.”
“I’d probably label something like that ‘specialization,’ which has been around for a long time,” she said.
Jonathan Martin, a meteorologist at the University of Wisconsin-Madison, has been tracking the size of this cold pool, tracing it back to when such reliable data began in the 1940s. Martin views the long-term cold pool data as a unique indicator of human-caused climate change.
“It’s one of the first free atmosphere, that is, away from the surface … measurements that conclusively show that the hemisphere is warming during the wintertime,” he said.
“The dice are loaded,” Martin said. As the world warms, it’s clear that cold pools are likely to keep shrinking and winters of the future are more likely to keep breaking warmth records.
Some young people are using chatbots “to test out being flirty or being romantic or being a little bit sexy and seeing how the chatbot responds to that,” Megan Moreno, a professor of pediatrics at the University of Wisconsin-Madison who studies technology and adolescent health, told me.
That kind of experimentation may be more common among boys, who generally engage in more risky behavior online than girls, Moreno said.
Bamboo is more absorbent and “can hold more moisture without feeling wet, compared to cotton,” Majid Sarmadi, textile expert at the University of Wisconsin-Madison, said.
So are these sheets actually bamboo? Technically, yes. They’re made from the bamboo plant, but that’s not the full picture. Sarmadi compared the process of creating bamboo rayon to making spaghetti noodles. “When you make spaghetti, it is 100% wheat, but it’s in a different shape,” Sarmadi said. In short, you grind wheat into flour, then mix it with other ingredients to create dough. So, think of bamboo cellulose as wheat. There are different ways to extract and treat it, but the cellulose eventually becomes the yarn you weave into fabric. The result is far different from bamboo stock, but it’s still part of the origin.
The link to mental health also has a physiological basis that researchers like Dr. Charles Raison are trying to understand.
“High heat administered for a time-limited period is an antidepressant and a pretty good one,” says Raison, a professor of psychiatry and human ecology at the University of Wisconsin-Madison.
University of Wisconsin junior Noah Warren studies political science with a special interest in geopolitics. But, Warren said he became frustrated when he found no free platform displaying a picture of politics across the globe — so he built one.
In a 2025 working paper, researchers from UW-Madison and the University of Southern California studied two decades of records of Wisconsinites who received food aid through the Supplemental Nutrition Assistance Program (SNAP), the most common way an employee qualifies for the tax credit. Researchers compared SNAP recipients who were eligible for the credit with similar recipients who weren’t.
:The bigger and broader your network is, the earlier you’re going to get data and direct access to global outbreak intelligence and alerts,” said Janis Tupesis, a Madison public health official and a global health expert at the University of Wisconsin-Madison. “That is super beneficial to the state.”
“The siting study includes looking at nuclear energy systems, anything from similar to today’s reactors that are operating to a variety of advanced reactor concepts, including microreactors and other smaller reactors, as well as fusion energy systems in the future,” said nuclear engineering professor and department Chair Paul Wilson.
Researchers can’t definitively say whether any of the men buried in the Kazakhstan mausoleums were related to Khan because they “still do not have a reference genome from Khan’s true relatives,” says lead author Ayken Askapuli, an integrative biologist at the University of Wisconsin-Madison, to the Badger Herald’s Allison Hayden.
“Colorectal cancer is the number two most common cancer in the United States,” Dr. Noelle LoConte, M.D., said. “It is decreasing, but not fast enough.”
“It’s hard to control the amount of carbon in the atmosphere, right, at the local level. But you can think about the things you can control,” says Zach Feiner, a fisheries biologist at the University of Wisconsin-Madison. “Maybe that means you make different harvest decisions. You keep fewer walleye. Maybe you decide to go fish for something … more resilient to harvest like a largemouth bass or bluegill that are more of a warm-water fish.”
Dorota Grejner-Brzezinska, a board member and the University of Wisconsin-Madison’s vice chancellor for research, expressed concern that fewer solicitations will lessen junior faculty’s ability to receive awards that jump-start their careers. She also said the agency’s practice of frontloading the funding of previously multiyear grants further reduces how many researchers receive grants in a year.
A study led by a University of Wisconsin researcher shows the first empirical documentation of digital voter suppression on social media and foreign election interference in the 2016 U.S. presidential election. The study was published Jan. 26 in the official journal of the U.S. National Academy of Sciences.
Historically, people valued the ice for other reasons. “There’s a long history of ice harvesting in this region,” says Hilary Dugan, a limnologist — someone who studies inland waters — at the University of Wisconsin, Madison. “So [there was] just a lot of commercial activity on these lakes, cutting blocks of ice out of the lakes all winter.”
The 2026 report is an update to the group’s more comprehensive 2021 assessment of climate change impacts on Wisconsin. Formed in 2007, the Wisconsin Initiative on Climate Change Impacts is a collaboration between the University of Wisconsin–Madison’s Nelson Institute for Environmental Studies and the Wisconsin Department of Natural Resources.
The visit follows a partnership announcement between the Public Service Commission and UW’s Department of Nuclear Engineering and Engineering Physics to study nuclear energy opportunities in the state.
Inside the University of Wisconsin Nuclear Reactor Tuesday morning, Wisconsin Governor Tony Evers peered over the shoulders of student operator Nick Tierney, a senior majoring in nuclear engineering, to eye the array of instrumentation on the reactor control panel, then climbed the stairs to look down into the reactor’s cooling pool.
The Badger Challenge is launching a new event to raise funds for cancer research at the University of Wisconsin-Madison.
The 2026 Badger Challenge Ball will bring together survivors, supporters, researchers, and community partners for a formal dinner, reception, and auction at The Edgewater. Set against the lakefront backdrop, the evening aims to celebrate hope while directly supporting life-changing cancer research.
Ignite Wisconsin’s grant of nearly $800K to the Wisconsin Fusion Energy Coalition will help push Wisconsin as a national hub for fusion energy.
Gov. Tony Evers, along with the Wisconsin Economic Development Corporation (WEDC), announced Thursday that the coalition, led by 5 Lakes Institute and UW-Madison’s fusion research work, will “accelerate startup formation, supply chain development, and community outreach in a sector projected to reach nearly $3 trillion by 2080.”
State utility regulators and the University of Wisconsin-Madison are partnering to explore potential nuclear energy projects in Wisconsin.
UW-Madison and the Public Service Commission will conduct a siting study to evaluate the suitability of various sites and the impact of projects on local economies. The study will also look at different reactor technologies, including both traditional nuclear power, advanced small modular reactors and fusion energy.
Co-authored by rofessor of environmental medicine, and djunct associate professor of Population Health Sciences, both at the University of Wisconsin-Madison.
“Health risks are increasing because human-cause climate change is already upon us. Take the 2021 heat dome for example, that killed (more than) 600 people in the Northwest,’’ said Dr. Jonathan Patz, a physician who directs the Center for Health, Energy and Environmental Research at the University of Wisconsin-Madison. “The new climate attribution studies show that event was made 150-fold more likely due to climate change.”
“We are often so externally focused that we don’t recognize what is going on in our minds, and when we begin to pay attention to that, it’s genuinely exhausting for most people,” Richard Davidson, a University of Wisconsin psychologist who studies meditation. It also can make us more anxious, at least at first.
University of Wisconsin-Madison leaders and students urged campus communities to strengthen civil dialogue, protect free expression and adopt a systemwide artificial intelligence vision responsibility at a Board of Regents meeting Thursday.
It’s like the World Cup. The stadium is on edge, and a player kicks the ball, scoring the winning goal.
The crowd erupts.
But at UW-Madison in Morgridge Hall, the soccer stars are autonomous humanoid robots.
Josiah Hanna, a UW-Madison assistant professor of computer sciences, leads the university’s student RoboCup team, which uses artificial intelligence to teach soccer-playing robots humanlike behaviors, all while producing research to advance the field.
Researchers at the University of Wisconsin-Madison discussed ethical concerns stemming from the rise of generative artificial intelligence in academia and research at a Jan. 30 panel.
The panel, which included experts from the UW-Madison Data Science Institute, Libraries and Institutional Review Boards Office (IRB), provided recommendations for researchers, offering definitions and opportunities for ethical AI use in research.
The University of Wisconsin-Madison has lost at least $27 million in federal research money since President Donald Trump upended the funding landscape in academia.
It’s the first time the state flagship has put a price tag on its losses since the Trump administration began cutting existing projects, delaying grant reviews and reducing the number of new projects getting funding.
The effects of the federal government’s cuts to UW-Madison’s research are coming into full view: $27 million lost in the last year from terminated or suspended grants.
A bill that would provide funding to a program that helps identify the remains of missing-in-action service members is in limbo after an Assembly committee put off a vote Wednesday due to concerns by Republican lawmakers that Gov. Tony Evers would use his partial veto on the measure.
The University of Wisconsin Missing-In-Action (MIA) Recovery and Identification project, which was started in 2015 at the state’s flagship campus, works to further the recovery and identification of missing-in-action American service members. Those working on the project include researchers, students, veterans, alumni and volunteers who conduct research, recovery and biological identification. The program is partnered with the federal Defense POW/MIA Accounting Agency (DPAA) on the work and has acted as a model for DPAA, which now partners with more than 50 other academic and nonprofit institutions to work on MIA identifications.
The scribe who copied Phaenomena, which details how various constellations rise and set, onto the parchment integrated descriptions of the stars’ positions that were probably based on Hipparchus’ work. The celestial objects’ coordinate system and accuracy align with references to the ancient astronomer’s writings, reports Science News’ Adam Mann. “There’s an appendix which includes coordinates of the stars discussed in the poem, and then little sketches of the star maps,” Minhal Gardezi, a physicist at the University of Wisconsin–Madison who is working on the project, tells the outlet.
The University of Wisconsin-Madison Global Health Institute convened experts from around the world with UW-Madison faculty for a Jan. 27 webinar examining the growing complexities of infectious disease control.
The discussion, moderated by Daniel Shirley, an infectious diseases professor at the UW-Madison School of Medicine and Public Health, brought together researchers working across human, animal and global health systems to address two converging crises: antimicrobial resistance (AMR) and declining childhood vaccination rates.
Clint Sprott, a UW-Madison physics professor who retired in 2008, started the show in 1984 as a free, public lecture. He still attends the show every year.
“[My] most favorite is seeing the smiles and enthusiasm of the audience,” Sprott said. “The show was a major part of my life for 40 years, and it is certainly fun to be something of a celebrity.”
Growing up in a first-generation Indian household, Armaan Jain was thrown into activities from a young age — baseball, basketball, soccer and everything but football. The packed schedule forced him to learn time management early, a skill reinforced by parents who deeply valued education and structure.
“From elementary school onward, I had to have systems in place to succeed,” he said. “I learned early that motivation isn’t always there, so you need something that keeps you going anyway.”
Almost every day for the last 24 years, my father and I have traded emails about Dictionary.com’s Word of the Day. We started the tradition when I was in fifth grade and he was 38, just a few years older than I am now. The rules are simple: Once we review the chosen word and its example sentences, whoever reads the email first forwards it to the other, including a short sentence typed up to put the day’s special word to use.
Infleqtion, a global leader in quantum sensing and quantum computing, announced research results from a collaboration with the University of Wisconsin–Madison that demonstrate a more reliable way to measure individual quantum bits, or qubits, without interrupting ongoing circuits. The work addresses one of the central challenges in quantum computing by enabling faster computation cycles while preserving fragile quantum states.
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.”
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.
To fill in this knowledge gap, the research team (led by scientists at the University of Wisconsin-Madison) analyzed two bacterial samples of Escherichia coli (E. coli)—one located on Earth, the other on the ISS, and both infected with what is known as a T7 bacteriophage. Eventually, they found that while the outcome of the arms race remained the same in each location—the bacteriophage eventually infected its bacterial prey—there were distinct differences in how this battle played out between the two samples.
“Space fundamentally changes how phages and bacteria interact: infection is slowed, and both organisms evolve along a different trajectory than they do on Earth,” the authors wrote. “By studying those space-driven adaptations, we identified new biological insights that allowed us to engineer phages with far superior activity against drug-resistant pathogens back on Earth.”
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.”
