Prediction market bettors don’t have prophetic powers: they are a “quantification of conventional wisdom,” said Ross Dahlke, a data science professor at the University of Wisconsin-Madison School of Journalism and Mass Communication.
The most common way to enrich uranium is by spinning uranium gas in a centrifuge, where lighter U-235 separates from the heavier U-238. This is done in stages, using multiple centrifuges that enrich the uranium bit by bit.
The early stages are especially labor-intensive because there is so much more U-238 to strip away, said nuclear security specialist Sébastien Philippe at the University of Wisconsin-Madison. Over time, the enrichment process gets easier.
The United States is one of only a handful of countries that allows companies to hold patents on plant varieties. As a result, a small number of corporations can – and do – suppress competition in the seed industry, stifle innovation and turn taxpayer subsidies intended for farmers into corporate profits.
Julie Dawson is a Professor and Extension Specialist in the Department of Plant and Agroecosystem Sciences at the University of Wisconsin-Madison. She told “Wisconsin Today” parts of Bayer’s rebate program would discourage smaller seed sellers — who buy seeds from seed giants like Bayer and re-sell those directly to farmers — from testing products from multiple companies and specializing what seeds they sell to their region or customer base.
Dr. James H. Stein, a cardiologist at the University of Wisconsin School of Medicine and Public Health, said a patient who listened to a podcast episode about cardiology now might arrive at his clinic and announce, “I have advanced heart disease and I need a coronary CT angiogram and I need you to measure my homocysteine level.”
UW Health dermatologist Dr. Lisa Arkin sat down with our Leigh Mills to talk about the risks of spending too much time in the sun or the tanning bed.
UW-Madison is responsible for another massive medical advancement — but this one was pharmaceutical, not biological.
Warfarin, one of the most widely used blood thinners on the market, began as a treatment for cows. A Deer Park farmer walked into the laboratory of Karl Paul Link, a biochemist working in the university’s College of Agriculture, because his cows had developed a bleeding disorder.
There have been Super Bowls and Rose Bowls on the field and World Series on the diamond. World championships have been won on the basketball court and national titles on the ice. Athletes like Henry Aaron, Bart Starr and Kareem Abdul-Jabbar weren’t born here, but they helped deliver trophies to our state.
“The state of Wisconsin was a part of their journeys to the hall of fame,” said Ashley Brown, the Allan H. Selig Chair in the History of Sport and Society at UW-Madison.
Some of Wisconsin’s justices disagreed with the ruling, but said they were bound by the U.S. Supreme Court’s precedent to strike down the grants. UW-Madison political theory Professor Howard Schweber says it’s important the public understands that nuance.
Wisconsin residents battling itchy eyes, runny noses and relentless sneezing this summer might figure this year’s allergy season is worse than years past. They would be right.
Question: What causes a thunderstorm?
Answer: Thunderstorm development requires three basic ingredients: moisture, unstable air and upward motion.
Moisture comes from regions like oceans, lakes and vegetation that provide the water vapor necessary for cloud formation and precipitation.
“For many years, we’ve had this testing program that basically looks at mice first as a first step to see what happens in an actual live organism, then rabbits, then dogs, then going on to humans,” said Nicole Nelson, UW-Madison associate professor of medical history and bioethics.
During a panel discussion at the U.S. News Healthcare of Tomorrow conference today in Washington, D.C., Antman; Dr. Sanjay Desai, vice dean for education at Johns Hopkins University School of Medicine in Maryland; Dr. Robert N.

Whelan, chief academic officer at the Association of American Medical Colleges, discussed ways to reduce the financial burden for aspiring doctors.
While rising prices can put a strain on both farmers and consumers, interest in organic products continues to remain high. In 2025, U.S. organic food sales grew three times as fast as the overall food market. This interest extends to organic beef, eggs and dairy, a trend that bolsters demand for organic feed grain.
Wisconsin’s protracted political redistricting fight took two turns in May: a federal court affirmed Wisconsin’s congressional district map and the U.S. Supreme Court further curtailed safeguards that have governed redistricting nationally.
A three-judge panel dismissed a lawsuit in the federal court case that challenged the congressional maps for Wisconsin. The case argued that the state’s congressional maps are “anti-competitive” and favor a Republican majority. The court ultimately ruled for the district maps to retain the district lines that resulted in a congressional delegation of six Republicans and two Democrats.
As three alleged planners of Wisconsin’s fake elector scheme pleaded not guilty Tuesday to 11 forgery-related criminal charges in Dane County court, the criminal charges against them are moving forward in a national legal and political landscape that looks dramatically different from the one in which they were filed.
We found no authoritative estimate that the number of Ku Klux Klan members in Wisconsin in the 1920s was 40,000.
That’s the current population of Wausau in central Wisconsin.
“No one knows for sure how many Americans joined during the 1920s but the best estimates are around 2 million members, some 15,000 of whom were in Wisconsin,” according to the Wisconsin Historical Society.
Researchers at the University of Wisconsin-Madison used optogenetics, a technique that controls genetically modified brain cells with pulses of light, to recreate the brain rhythm of deep sleep in mice that were fully awake and moving.

Participating in physical activity, particularly while surrounded by “elements of nature,” can improve classroom focus and concentration for young students, said Dr. Dipesh Navsaria, a UW professor of pediatrics and human development and family studies. Yet environmental and economic disparities can prove significant barriers to many, he said.
Teams of researchers at the University of Wisconsin-Madison spent months submitting proposals to the Department of Energy’s vast new Genesis Mission — an initiative centered around artificial intelligence (AI) but naming research goals in fields as varied as nuclear fusion and molecular biology. Many of UW-Madison’s proposals center around one burgeoning cross-college priority: quantum.
In Philadelphia, New York and Boston, American colonists were preparing to pledge their lives, fortunes and sacred honor to declare their independence from an oppressive monarch.
But in the faraway frontier territory that would later become Wisconsin, Native and European peoples were on a wholly different journey in 1776.
UW-Madison Wisconsin Center for Education Research scientist Bradley Carl explains the basis for school districts holding referendums and the choices faced by voters being asked to raise local taxes.
Q: I eat frozen yogurt regularly, assuming it’s better for me than ice cream. Is it?
Since frozen yogurt took off in the 1970s, it has been pitched as a healthier alternative to ice cream. In TCBY advertisements from the 1990s, their low-calorie, nonfat version was said to have “all of the pleasure, none of the guilt.” Today, some Greek yogurt shops tout gut-friendly probiotic benefits.
A new federal rule aimed at increasing access to nutritious foods for SNAP recipients is raising questions for some small grocery stores in rural communities.
The U.S. Department of Agriculture announced in May that retailers participating in the Supplemental Nutrition Assistance Program (SNAP) will be required to carry a wider variety of staple foods beginning in November.
Last month, when the Trump administration reached an agreement with Bayer to curb what officials lambasted as anticompetitive practices, Agriculture Secretary Brooke Rollins hailed it as a win for farmers. But she cautioned the concentrated nature of the seed industry required continued antitrust vigilance.
The University of Wisconsin-Madison offers a handy tool that uses data from a NOAA satellite and other resources to track the Saharan air layer as it ebbs and flows across the globe.
By inducing specific patterns of activity in small portions of the brain in awake mice, researchers have triggered a recalibration of neural connections that normally only occurs during sleep. This new approach offset the effects of sleep deprivation on memory tasks and revealed features of sleep that are key to its restorative effect.
A researcher at the University of Wisconsin-Madison has published a paper that demonstrates hybrid combinations of lignocellulosic feedstock pretreatment methods can achieve high glucose yields with reduced energy consumption.
In his article in The Atlantic, grimly titled, “America is sliding toward illiteracy,” Idrees Kahloon uses data largely from the National Assessment of Educational Progress, or NAEP, to reflect on the recent degradation of American education. Kahloon uses this data to test theories as to why K-12 test scores have plummeted since 2007 after a brief but substantive window of improvement.
PBS Wisconsin’s University Place will record “An Overview of the Geology of Wisconsin,” a presentation by Sue Swanson, Ph.D., Director of the Wisconsin Geological and Natural History Survey (WGNHS) and State Geologist.
Question: What is the prediction for the 2026 hurricane season?
Answer: Tropical cyclones are large, whirling storms that obtain their energy from warm ocean waters.
Roughly 20 million Americans live in manufactured houses, which are made in factories.
Though they’re often called mobile homes or trailers, that’s really a misnomer because their owners can’t easily relocate them. Typically, the people who own them rent the land underneath the houses from the owners of parks for manufactured home. Sometimes an owner will rent their home to someone else while paying to rent the land as well.
The Joint Committee on Finance approved the $10 million sale of the state’s former Human Services building to Landmark Development Tuesday, bringing Madison one step closer to getting Amtrak service.
A key part of the company’s plan is to bridge gaps between Madison and other Midwestern cities.
“Madison is ideally situated amongst the sort of arc of bigger cities within the Midwest. We really can play a key position economically, culturally, politically, by the location we have,” Jason Ilstrup, the president of Downtown Madison Inc., said.

Here’s what guests on the May 29, 2026 episode said about broad voter support for a failed state surplus deal, prospects for job seekers, and a lawsuit over ICE holds by sheriffs.
Dairy producers across Wisconsin now have a new tool to help manage one of summer’s biggest challenges: heat stress. It costs the U.S. dairy industry significantly each year through reduced milk production, lower fertility, and added health expenses. At the same time, the cost of running the fans and ventilation systems that prevent those losses keeps rising, making smart decisions on the farm matter more than ever.
Instead, the former judges, representatives of Law Forward, the Wisconsin Association for Justice and directors of the State Democracy Research Initiative at the University of Wisconsin-Madison suggest the Wisconsin Supreme Court should establish an advisory committee to study what process would work best in Wisconsin.
The Wisconsin Alumni Association hosted a webinar on May 19, “From War to AI: Forces Shaping Today’s Economy,” examining how conflict, global trade disruptions and artificial intelligence are influencing the United States and global economy.
The two are also concerned that the district could ignore some of the equity and teacher well-being issues raised in a report led by a group of students from UW-Madison’s La Follette School of Public Affairs, which found that teachers felt burnt out by monitoring phone use and want more district support, and that low-income Black and Latino students in the Madison School District face disproportionate levels of device-related discipline.
Requests to remove or restrict access to books in schools have hit record highs both across the country and in Wisconsin.
In May, Wisconsin upheld the Menomonee Falls School District’s finding that the 2024 removal of a children’s book that depicted multiple family structures, including ones with LGBTQ+ couples, did not count as discrimination.
The median home cost in Wisconsin’s two biggest metro areas is at least five times the median household income in those communities, among the highest in the Midwest.
Resistant and emerging pests are on the rise, leaving farmers scrambling for information on control options.
Corn earworm flexed its might last year in Wisconsin fields.
Maks Makarenkov couldn’t help but smile on car rides through the capital city. He saw homes with blue and yellow flags pinned in their windows or dangling from flagpoles.
“Seeing the Ukrainian flags here, it touches my heart,” Makarenkov said. “In this war, we feel the American support.”
Professional Dairy Producers will feature two educational sessions this week through its weekly The Dairy Signal program, offering dairy producers updated information on herd management and market conditions affecting the industry in 2026.
The Tuesday, May 26 episode will focus on improving reproductive performance on dairy farms. The session will examine current reproductive protocols, management strategies, and recent research findings designed to help producers strengthen herd efficiency and productivity.
Magnetic fields are found everywhere in the universe, from planets and stars to entire galaxies. These invisible forces influence major cosmic events and processes, including solar storms, the movement of high energy particles, and even galaxy formation. While small magnetic fields are often chaotic and turbulent, much larger magnetic structures appear surprisingly organized. For decades, scientists have struggled to explain how disorder in space could create such large-scale order.
Question: What is fire weather?
Answer: Wildfires need three essential elements: heat, oxygen and dry fuel. Fire weather refers to a mix of meteorological conditions that make it easy for wildfires to ignite and spread quickly. The main weather factors are low humidity, strong winds, warm temperatures and atmospheric instability.
As more than two billion people worldwide still lack access to safely managed drinking water, new research from the La Follette School of Public Affairs at UW–Madison investigates the effects of early-life exposure to citywide water filtration on longevity in the early 20th century.
A teenager knows something isn’t right. They want to talk to a therapist but don’t want their parents to know everything they say. In Wisconsin, whether the teen can control that decision depends on a set of laws, hinging on the age of the minor, that most teens and many parents do not fully understand.
No one could have predicted the massive spread of golden oyster mushrooms in the United States.
The golden oyster mushroom, or Pleurotus citrinopileatus, seems like an innocent and edible fungi, but it has become a rapidly spreading, invasive species throughout the central and northeastern United States.
In the last 15 years, it has been found in moist woodlands throughout Missouri, especially the upper part of the state and in Boone County.
Mention the “Dream Team” to a longtime sports fan, and they will assume you’re referring to the 1992 U.S. men’s Olympic basketball team, a powerhouse with a roster that included Michael Jordan and Magic Johnson.
University of Wisconsin-Madison professors, Jane Paulsen and Michael Newton discovered that two proteins decline in the human brain as Huntington disease develops, furthering improvements for treatments of the disease.
Huntington’s disease (HD) is a rare, genetic disease that causes neurons in the brain to degenerate over time, affecting a person’s movement, cognition and overall quality of life.
To understand psychedelics — those powerful and cryptic agents of the mind — scientists are exploring uncharted landscapes. “We don’t yet really know why psilocybin or other psychedelic drugs seem to have the effects that they do,” Professor Paul Hutson, director of the University of Wisconsin-Madison Transdisciplinary Center for Research in Psychoactive Substances, told the Wisconsin Examiner.
Question: Who or what triggers the decision to sound a tornado siren?
Answer: The National Weather Service is responsible for issuing forecasts, watches and warnings for a variety of weather and water hazards. A “warning” is issued when hazardous weather poses an immediate threat to life or property.
