Protecting the Guardians: What Brazil and Germany Teach Us About Defending Constitutional Courts against Populism
A constitutional court is built to do something almost no one else in a democracy can do: tell the majority it has gone too far. But a court has no army, and no budget of its own. Whether its rulings mean anything depends on other people choosing to honor them, including the officials who must carry them out, and, as Barry Friedman has argued, the public that those officials ultimately answer to. That dependence is the soft spot at the heart of judicial power, and populists everywhere have figured out how to press on it.
Study suggests eating less protein could be key to healthy aging for most adults
A major scientific review is challenging the idea that more protein is always better.
The review, led by pathologist and biomedical researcher Dudley Lamming and published in the journal Cell Press Blue, examined more than 350 studies involving humans, mice, insects, yeast, and other organisms.
11 million pounds of uranium may have been shipped to China unofficially, finds study
Researchers at the University of Wisconsin-Madison and Princeton in the US have found that between 2000 and 2024, large quantities of uranium were extracted, concentrated and exported from the Democratic Republic of Congo (DRC) as part of the country’s cobalt supply chain.
Massive quantities of undeclared uranium are exported from the DRC, study reveals
University of Wisconsin–Madison and Princeton University nuclear engineers have identified a major blind spot in nuclear accounting with global nuclear security implications.
DR Congo’s cobalt boom carries an unwanted cargo: uranium
“Limited adoption” of uranium-removal processes such as the use of acid “suggests that consistent compliance with this threshold is unlikely”, wrote the authors, Ryan Manzuk of Princeton University and Sébastien Philippe of the University of Wisconsin–Madison.
Madison faces familiar pain, questions a week after police shooting
Ion Meyn, an associate professor of law at the University of Wisconsin-Madison, reviewed videos shared on social media and Patterson’s remarks about the shooting at the request of the Cap Times. Meyn called the shooting unnecessary.
“What’s particularly egregious to me is that this person seems to have been going into compliance at the time he was shot in the head,” Meyn said.
John Gross, a clinical associate professor in UW-Madison’s Law School who researches police use of force, also reviewed the videos. He questioned whether there were opportunities for officers to de-escalate the situation before making physical contact with Ruiz.
Hot, dry July hitting farmers as parts of Wisconsin in drought
“I know they’re getting some really beneficial rain in the eastern part of the state today,” said James Otkin, a drought expert at UW-Madison. “But for us here in Dane County, it’s been another hot, dry week. And generally speaking, it’s been pretty much dry across much of the state again.”

New UW Research Shows Farmers Markets Build Community
A trip to your local farmers market may be doing more than filling reusable bags with fresh produce. New research from the University of Wisconsin–Madison shows those visits are also helping build a stronger, more connected community.
The study, published in Information, Communication & Society, found that people who regularly attend farmers markets report higher levels of community participation. They also have a stronger sense of belonging than those who rarely or never attend.
Getting to the root of common plant diseases
Gardening season is in full bloom in Wisconsin, but while your perennials and their pollinators are peaking, so too are those nasty plant diseases that can filter into your flowers and victimize your vegetables.
Brian Hudelson, the director of the University of Wisconsin Extension’s Plant Disease Diagnostics Clinic, recently joined Jill Nadeau on WPR’s “Garden Talk” to discuss what ailments may be plaguing your plants.
Bryna Godar on WEC’s ruling on ‘spoiling’ absentee ballots
We turn to Bryna Godar, attorney with the State Democracy Research Initiative at the University of Wisconsin Law School, and thanks for being here. So I want to just back up a little bit to set those court cases up. It was a 2022 lawsuit where a Waukesha County judge ruled that the elections commission had to rescind its guidance, allowing for the spoiling of ballots. A state appeals court eventually repealed that ruling.
Measles Cases Hit New Record in U.S., as Vaccination Rates Wane
The United States has now recorded more cases of measles in 2026 than in any other year since the virus was declared eliminated in 2000, a grim sign that the country may be headed toward a new era in which the disease regularly sickens thousands every year.

UW law professor: Madison shooting unnecessary, will be justified by police
The recent shooting of Corey Ruiz, a 38-year-old Black man in Madison, is another example of police unnecessarily taking a life. Yet police will likely find that taking his life was consistent with officer training and justified.
Scientists at Rhinelander research station welcomes public to see new potato crop innovations
At the Rhinelander Agricultural Research Station in Rhinelander, UW-Madison professors and grad students are working hard and trying to find new ways to help potatoes grow.
Legal expert details independent investigation of deadly Madison police shooting
Ion Meyn, a UW Law professor who teaches civil and criminal procedure, told News 3 Now that the investigation protocol is “not as independent as it may seem.”
Meyn explained that investigators often follow different procedures when examining police-involved shootings compared to standard criminal investigations. One significant difference involves the timing of officer interviews.
UW-Madison researchers question fatal shooting by Madison police
As Madison reels from the deadly shooting of Corey Ruiz by a police officer this week, two professors who study police use of force say many questions remain unanswered about how officers responded.
FEDERAL COURT SAYS CHANGES IN POLICY PRIORITIES DON’T JUSTIFY USDA GRANT TERMINATIONS
The National Sustainable Agriculture Coalition says a recent federal court ruling clarifies that agencies cannot terminate funding because a new administration has different policy priorities.
Deputy Policy Director Sophia Kruszewski tells Brownfield, “The court says in its opinion that authority applies to the priorities as they were at the time the agreement was entered into.”
“It doesn’t create this broad authority for the agency to change its mind and then hold existing agreements to new and changing priorities,” she explains.
Is buying into a prediction market OK if you’re voting in Wisconsin?
The bipartisan Wisconsin Elections Commission is warning voters that they shouldn’t buy into prediction markets like Kalshi or Polymarket on the results of a Wisconsin election and then vote in that same race.
That’s because voters could be violating a decades-old Wisconsin statute that carries felony-level consequences – though it doesn’t appear the state has recently enforced it or proactively plans to hunt down lawbreakers.
As Democrats aim to retake the Wisconsin Legislature, here are the races we’re watching in the Aug. 11 primary
The upcoming Wisconsin midterms could shift the balance of power in the state Legislature, and the August primaries will determine which candidates voters want to see on the November general election ballot.
Democrats are aiming to flip both the Assembly and Senate in hopes of securing a trifecta in the state government. The party must flip two of the four competitive Senate seats to win a majority. The Assembly is a larger challenge as Democrats must flip five seats to claim a majority for the first time in 16 years.
Canadian wildfire smoke devastates Madison businesses during Maxwell Street Days
What should have been one of the busiest weekends of the summer for downtown Madison businesses turned into a major disappointment as Canadian wildfire smoke created hazardous air quality conditions throughout the region.
The smoke essentially formed a black cloud over Maxwell Street Days, significantly impacting vendors and their bottom lines. Business owners reported drastic declines in foot traffic and sales during what is typically a peak revenue weekend for small businesses in the area.
UW Madison Drops Flock Safety, Reconsiders License Plate Readers
Now that UW-Madison police have cut ties with Flock Safety, privacy advocates and others on campus say the community needs to be more involved in deciding which automated license plate readers, if any, the department uses in the future.
When eight of the company’s cameras first appeared on campus in July 2025, many people were taken by surprise, said Annette Zimmermann, a UW-Madison data science professor.
Danger not over as wildfire smoke gives Madison first-ever ‘hazardous’ air quality
Dane County has seen more frequent air quality warnings over the past decade, but the area had yet to experience hazardous levels. That was until Thursday.
As more than 100 wildfires burn in Canada and northern Minnesota, southeast winds carried smoke across the Midwest this week. Shortly before noon on Thursday, a monitor in Madison recorded an air quality index of 450.
The science behind the smoke: What’s driving wildfires that are sending thick smoke to Wisconsin
The smoke blanketing Wisconsin Thursday wasn’t subtle. You could see it, smell it and sometimes feel it while breathing. It was the product of wildfires burning in northern Minnesota and Ontario. Dr. Mayra Oyola, an atmospheric scientist at UW-Madison, said dry and windy conditions are fueling those fires. Typically, rain is helpful to fight fires, but Oyola said storms can pose a new challenge: lightning. Lightning strikes can ignite more fires.
State health officials confirm 43 cases of Cyclosporiasis, WI farmers on alert
“I feel bad saying this because it’s summer and everybody wants to eat fresh produce, but there isn’t really a safe way to wash it,” said Laura Knoll, a professor of medical microbiology at UW-Madison.
While the current outbreak has not been linked to produce sold by local farmers in Wisconsin, it’s still top of mind for farmers in the state.
AIR QUALITY WARNING: Wildfire smoke is moving into Wisconsin — here’s what doctors say you should do to protect yourself
Wildfire smoke moving into Wisconsin is bringing a surge of tiny particles that can travel deep into the lungs and cause irritation and inflammation, according to a UW Health allergist.
Dr. Mark Moss said the particles are a concern for anyone spending time outdoors, but pose a greater risk to certain populations.
Wildfire smoke moves into southern Wisconsin, bringing air quality advisories into at least Friday
Smoke from wildfires in Canada and northern Minnesota moved into southern Wisconsin on Thursday, bringing advisories through noon Friday that may be extended for some parts of the state.
Dane and other counties in south-central Wisconsin are under an “unhealthy for all groups” advisory, counties to the east are under a “very unhealthy for all groups” advisory, and counties to the west are under “unhealthy for sensitive groups” and “moderate air quality” advisories.
Aggressive Lone Star Tick closing in on Wisconsin
Summer is the most cherished time of year for Wisconsin residents. After a harsh winter, there’s nothing better than spending your days outside.
However, every good Wisconsinite knows a day spent out in a forest or at a lake is not complete without a tick check.
Every kid knows to look for ticks because they can cause Lyme disease, but a different tick species popping up in Wisconsin is a new reminder to check.
Wisconsin dairy plants adjust to cottage cheese demand
Aerica Bjurstrom, a regional dairy educator with the University of Wisconsin-Madison Division of Extension, said interest in the product is good news for the state’s dairy farmers.
“I think a lot of this innovation is coming from people in their own kitchens,” she said. “I think a lot of this boom in cottage cheese is coming from social media.”
Diarrhea-causing parasite found in Wisconsin and 30 other states
People become infected with cyclospora by consuming contaminated fresh produce or untreated water. Cases pick up in warmer months, because more people are eating fresh fruits and vegetables, said Dr. Jim Conway, a UW Health Kids pediatric infectious disease doctor.
5 threats to soybeans during excessive heat
Weather forecasters expect this to be one of the warmest growing seasons on record for much of the Midwest.

How effects of a ‘super’ El Niño will feel in Wisconsin
Dan Vimont has a depressing prediction for anyone concerned about climate change.
“We will almost definitely shatter the global temperature record in 2027,” said Vimont, a professor of atmospheric and oceanic sciences at the University of Wisconsin-Madison.
The Strange Phenomenon of ‘Terminal Lucidity’
When Andrea Gilmore-Bykovskyi, an associate professor in emergency medicine at the University of Wisconsin-Madison, saw that the N.I.A. was interested in video research on lucid episodes, she knew one way to approach the problem. Her past work had involved filming people with dementia during interactions with nursing staff and then meticulously analyzing the videos, second by second, to assess which types of care affected patients’ behavioral symptoms. She proposed retooling those video methods to study lucidity.
Madison researchers studying aortic dissection that killed Sen. Lindsey Graham
Early findings indicate Sen. Lindsey Graham died from an aortic dissection— a condition that UW Health researchers in Madison are actively studying.
An aortic dissection occurs when a layer of the body’s main artery separates, disrupting blood flow to vital organs.
Dr. Paul DiMusto, a UW Health vascular surgeon and co-director of the UW Health Aortic Center, said many patients have no symptoms until the event occurs, and it is often life-threatening.
NOAA provides key data around wildfires
Question: Does NOAA conduct fire weather forecasting?
Answer: Wildfire outbreaks require the alignment of several factors, including temperature, humidity, winds and the lack of moisture in fuels such as trees, shrubs and grasses. These factors have strong direct or indirect ties to current weather, climate variability and climate change. The National Oceanic and Atmospheric Administration supports weather forecasting throughout a wildfire’s lifecycle: before, during and after the wildfire.
Drought conditions can set the stage for wildfires.
U.S. Underestimates Peril if Los Alamos Were to Leak Plutonium, Study Says
The Energy Department has underestimated the potential deadly consequences should plutonium escape the Los Alamos National Laboratory in New Mexico, which produces bomb cores for America’s nuclear weapons, a study published today by independent scientists found.
THE OWL WARS Northern spotted owls were spared from logging. Now, scientists are making a last stand to save them from a new threat
The University of Wisconsin–Madison (UW) wildlife ecologist quickly swung into action. He placed a small speaker on the hood of the truck and set it to play the same “Who cooks for you?” call on repeat, an irresistible provocation for the aggressively territorial owl species. Then, he pulled his 12-gauge Beretta shotgun from the truck’s cab and snapped a single birdshot-packed cartridge into place.
Why scarlet lily beetle has Wisconsin gardeners seeing red
Lily leaf beetle, also called scarlet lily beetle, is an invasive species that is native to parts of Europe and Asia. It first showed up in Wisconsin in 2014 in the Wausau area. It likely came in with infected nursery stock to a garden center or big box store in that part of the state and was then purchased by customers who moved the plants elsewhere, said entomologist PJ Liesch, director of the University of Wisconsin-Madison Insect Diagnostic Lab.
GLP-1 drug popularity is outpacing the science, Madison doctor says
The explosive popularity of GLP-1 drugs like Ozempic, Wegovy and Zepbound is transforming the way Americans treat obesity, with demand soaring beyond doctors’ offices and into online marketplaces, med spas and unregulated gray-market vendors. And while the medications are helping many people lose significant weight and improve their health, one Madison doctor warns the trend is outpacing the science.

Wisconsin wasn’t a state in 1776. What did life look like here 250 years ago?
“Those included people who have lived in what we call Wisconsin for time immemorial,” University of Wisconsin-Madison history professor John Hall said, including the Ojibwe, Dakota, Menominee and Ho Chunk. It also included the Sauk and Meskwaki, who were not indigenous but had migrated over the preceding century.
Wisconsin’s oversized influence on American sports
Athletes like Henry Aaron, Bart Starr and Kareem Abdul-Jabbar weren’t born here, but they helped deliver trophies to our state.

Phosphorus remains one of the region’s top concerns for lake health, said Hilary Dugan, an associate professor and researcher at UW-Madison’s Center for Limnology, which studies inland lakes.
UW Health shares heat safety tips as dangerous temperatures grip region
“As your water balance gets off, your electrolytes get kind of a little sideways, you start having cramps,” said Dr. Jeff Pothof, an emergency medicine doctor with UW Health. “If you’re sweating profusely and you’re feeling lightheaded when you stand up, and now you’ve got this cramp in your calf that just won’t go away, that’s your body telling you you are not doing OK. You’ve got to get out of this heat, get yourself hydrated before you get more ill.”
Doctor warns sparklers aren’t as safe as parents think this Fourth of July
Children wearing sandals can suffer deep burns to their feet when they drop sparklers, according to a UW Health emergency medicine physician. Dr. Jeff Pothof said burns to fingers or the side of the head are also common injuries he sees.
Can solar energy and farming share the same land? These Wisconsin researchers think so
As solar power makes up a bigger piece of our electricity puzzle, there’s a worry about a trade-off, especially in rural areas: If we build more solar farms, are we losing land for crops?
But University of Wisconsin-Madison scientists are asking the question: Why can’t we have both?
Opinion: Storm clouds over Social Security solvency hovering closer
Wisconsin is no stranger to Social Security. The modern Social Security system has Wisconsin roots: faculty at UW-Madison led the creation of the program nearly a century ago.

How Wisconsin became “The Beer State”
“We had great abundant soils where we could grow barley and wheat, hops, and we had plenty of water that was readily available,” said Robin Shepard, a Madison-area beer writer and assistant dean of UW-Madison’s Department of Extension. “Those were the things that really came together to make it the perfect storm for brewing.”
Wisconsin immigrants’ rights advocates celebrate birthright citizenship ruling by US Supreme Court
“Per the executive order, no one would be losing their citizenship,” Erin Barbato, the director of the Immigrant Justice Clinic at the University of Wisconsin Law School, explained.
Still, Barbato said the order had the potential to cause “chaos.”
Wisconsin Democratic primary for governor turns negative
Six weeks out from the Democratic primary, which will decide which of six remaining candidates will be on the ballot in November, voters are largely tuned out, said Barry Burden, a political scientist at the University of Wisconsin-Madison.
What to know about the Wisconsin Supreme Court’s ruling on Menominee land buyback
Torey Dolan, assistant professor of law at the University of Wisconsin Law School, joined WPR’s “Wisconsin Today” to talk about the history of the case and what the ruling could mean for tribal land buybacks around the state.
Court rules tribes can buy back land, Green energy and agriculture, Baseball for breakfast
Last year, a solar project in Dane County opened with the idea of combining green energy and farming. Known as “agrivoltaics,” the co-location of solar energy and agriculture, the Kegonsa Research Campus is one of the largest in the country. We hear University of Wisconsin-Madison’s Ankur Desai, who is a leader in the project.

Steve Ackerman and Jonathan Martin, professors in the UW-Madison Department of Atmospheric and Oceanic Sciences, say with only a few exceptions, it seems as if this year’s run-up to summer, which arrived at 3:24 a.m. Sunday, June 21, was relatively mild. By that, they mean very few really oppressively hot and humid days.
These are the biggest and most common spiders in Wisconsin
PJ Liesch, director of insect diagnostic lab at the University of Wisconsin, said spiders often get a bad rap, but they really aren’t going to bite humans. Humans aren’t food to them, so they’d really only ever do it in self defense.
These Unpaid Interns Want $32 an Hour. And Health Insurance.
Fast forward to today, and the end is nowhere in sight.
About four in 10 interns still don’t make money, according to some labor estimates.“It still feels kind of ludicrous in 2026 that we’re still having this conversation,” said Matthew Hora, a University of Wisconsin-Madison professor who studies the transition from higher education to the labor market.
Sweeping federal housing bill won’t be a magic bullet for Wisconsin affordability, experts say
Research varies about the scale of Wisconsin’s housing shortage, but according to the think tank Forward Analytics, the state needs somewhere between 84,000 and 140,000 new units of housing by 2030 to keep up with population demand.
“Which is a short time period,” said Kurt Paulsen, who teaches and researches affordable housing finance and policy at UW-Madison.
