It’s important to note, however, that the study’s findings are limited — researchers conducted testing on mice and only tracked health effects for about three days after exposure. Plus, microplastics are difficult to quantify — if another team of researchers did the same study, their findings may vary, says Hoaran Wei, an assistant professor in the department of civil and environmental engineering at the University of Wisconsin-Madison.

Ask the Weather Guys: Does North America have a hurricane season?
FEMA Director David Richardson recently claimed he was unaware that there is a hurricane season in the United States. There most certainly is such a season.
The Atlantic hurricane season climatologically runs from June 1 through Nov. 30, with the most active part of the season being mid-August through mid-October.
UW-Madison to add Korean major amid popularity of K-pop and K-dramas
When Ava You applied to attend the University of Wisconsin-Madison, she looked to see if she could major in Korean.
“Honestly, I was a little disappointed considering they had a Chinese and a Japanese major already, but not Korean,” said You, an incoming sophomore at the flagship campus.
That will soon change when UW-Madison introduces a bachelor’s degree in Korean Language and Culture this fall. The Board of Regents, which oversees UW-Madison and the state’s 12 public universities, granted final approval this month. UW-Madison will be the first school in the Universities of Wisconsin to offer an undergraduate program in Korean.
Dealing with Sunday scaries? Here’s how to address that anxiety.
A person can feel anxious on a Sunday for two reasons, said Jack Nitschke, a psychologist and neuroscientist at the University of Wisconsin-Madison. You’re anticipating plans for the upcoming week, and the future is inherently uncertain.
Wisconsin man’s case raised the competency standard for execution. He died at 67 on death row.
Panetti died from acute hypoxic respiratory failure on Texas’ death row the morning of May 26, the macabre space he called home for more than 30 years. There, he was known as The Preacher, according to his longtime lawyer, Greg Wiercioch, now a clinical professor at the University of Wisconsin Law School. Panetti was 67 years old. He had four children.
Wisconsin military historian says situation in Los Angeles could ‘absolutely’ happen here
“[The president] has made clear that his definition of what constitutes unlawful combinations, in terms of protests, is relatively low,” said John Hall, a military historian at the University of Wisconsin-Madison and a retired U.S. Army Reserve colonel. “So where protests emerge, he has threatened he will take similar measures to respond to those protests.”
“Moreover, he seems to be suggesting that states and municipalities that, in his judgment, are interfering with ICE’s mass deportation efforts right now are themselves obstructing the laws of the United States,” Hall continued.
Sasha Maria Suarez on revitalizing Indigenous languages
UW-Madison history professor Sasha Maria Suarez describes programs by tribal nations, K-12 schools and higher education institutions to teach Wisconsin’s Indigenous languages to learners of all ages.
I found power, confidence and calm at a poker table full of men
Poker puts into focus the same gender dynamics that can create anxiety for women in a patriarchal society, says Jessica Calarco, a sociologist, professor at the University of Wisconsin-Madison, and author of ”Holding It Together: How Women Became America’s Safety Net.” “You’re expected to read the room, stay composed, and manage risk — much like women do every day in a world that asks them to carry everything without appearing to struggle,” she tells me.
How viruses can help the fight against antibiotic resistance
“One approach is to create more antibiotics but this only postpones the problem. New antibiotics also can lead to new forms of resistance, creating a never-ending cycle. An alternative and promising solution is phage therapy, which uses viruses called bacteriophages (or simply phages) to kill specific bacteria,” said Dr. Anantharaman, a professor at the University of Wisconsin-Madison.
UW-Madison lake researchers face uncertainty over potential cuts to the National Science Foundation
UW-Madison researchers, who study Wisconsin’s lakes, are grappling with uncertainty as cuts to the National Science Foundation (NSF) could threaten decades of freshwater research.
Professors Emily Stanley and Hilary Dugan from the UW-Madison Lab for Limnology have dedicated their careers to studying freshwater systems, with Lake Mendota serving as a key research site.
Many falls are preventable. These tips can help.
Many falls can be prevented, said Dr. Gerald Pankratz, a geriatrician at the University of Wisconsin-Madison. That makes him “optimistic about this issue,” he said.
In his practice, Dr. Pankratz said, it is not unusual for people assessed as having a 50 percent chance of falling over the next year to cut their risk in half by taking action to avoid slips and trips.
Wisconsin state lawmakers, industry experts share concerns about proposed limits to AI regulation
University of Wisconsin-Madison professor Annette Zimmermann is a political philosopher of AI and co-lead of the school’s Uncertainty and AI research group.
“Much like many other experts working in this area, I’ve been deeply concerned about imposing such a heavy handed blanket ban on any sort of state-based efforts to effectively regulate this space,” Zimmermann said. “Right now, unfortunately, we’re in a regulatory landscape where we are heavily relying on individual states to think very hard about how to protect ordinary citizens and consumers from these kinds of harmful outputs.”
UW Health, SSM Health change language related to DEI on parts of websites
UW Health and SSM Health said removing and changing DEI language on parts of their websites doesn’t change their commitment to care — but advocates for marginalized communities say it’s cause for concern.
Wisconsin health officials say RFK Jr. ‘destroying trust’ with purge of CDC vaccine panel
Dr. Ajay Sethi, a professor of population health sciences at the University of Wisconsin-Madison, told the Journal Sentinel in May he worries changes in federal guidance may encourage adults who were already on the fence about the COVID-19 booster to skip it.
RFK ousts all 17 members of a vaccine advisory panel
“ACIP has been, across the entire world, the paragon of good, solid, well-thought-out, evidence-based vaccine policy. I hate to say this. We are heading in the direction of U.S. vaccine policy becoming the laughingstock of the globe,” said Dr. Jonathan Temte, former chair of the ACIP and a professor at the University of Wisconsin.
Republicans Trying to Control Indiana University Meet Little Resistance
“There’s this shifting mentality that the state is the owner of these institutions — it’s not the students, it’s not the alumni,” said Isabel McMullen, a doctoral student at the University of Wisconsin-Madison who studies public university boards.
Clinical psychologist explains how ADHD drugs work, addresses unscientific harm concerns
James Li is the A. A. Alexander Associate Professor of Psychology and an investigator at the Waisman Center at the University of Wisconsin-Madison. He told WPR’s “Wisconsin Today” that Kennedy’s statements on the harms of medications like Adderall aren’t based in science.
“The evidence is quite clear that the medications that are currently FDA-approved and prescribed to treat ADHD in particular are fairly well tolerated. They don’t lead to early mortality … and they are generally very beneficial when used properly under doctor’s orders,” Li said.
Pressure mounts on UW animal research
Dr. Eric Sandgren, a professor emeritus at the UW-Madison who headed the university’s animal research operations for a decade, ending in 2016, calls these directives “nothing new.” Researchers, he says, have for some time been moving away from the use of animals as other models have become viable. “This just formalizes something that’s happening already.”
State health officials urge kids, pregnant women to get COVID-19 vaccine despite federal pullback
Federal vaccine recommendations matter not just because the public pays attention to them, but because it can affect which vaccines insurers decide to cover, said Patrick Remington, emeritus professor at UW-Madison’s School of Medicine and Public Health.
Don’t rinse raw chicken: nine food safety tips from microbiologists
Dr Jae-Hyuk Yu, a professor of bacteriology at the University of Wisconsin-Madison, recommends using a bleach solution (one tablespoon of bleach per gallon of water), an Environmental Protection Agency-registered kitchen disinfectant, or an alcohol-based spray for sanitizing hard surfaces, especially after preparing raw meat. And when handling cleaning chemicals, use gloves and ventilate well. He recommends cleaning fridge shelves monthly and ensuring your fridge is consistently under 40F (4C) to prevent bacteria from lurking around.
What to know about Fusarium graminearum, the biological pathogen allegedly smuggled into the US
Breakouts of Fusarium graminearum infections already naturally occur in dozens of U.S. states — basically any state that produces wheat and barley — and has been established in the U.S. for at least 125 years, Caitlyn Allen, a professor emeritus of plant pathology at the University of Wisconsin-Madison, told ABC News. In addition, the U.S. Department of Agriculture keeps a list of potential agroterrorism agents, and Fusarium graminearum is not on that list, Allen said.
“We’re not talking about something that just got imported from China,” Allen said. “People should not be freaking out.”
Tick tock: Timing out a busy tick season in Wisconsin
“Ticks have been active for quite a while now,” said P.J. Liesch, the director of the University of Wisconsin-Madison Insect Diagnostic Lab. “It’s something that can often catch folks off-guard. We might not be thinking about ticks in those winter months — January, February, March — but once temperatures get above freezing consistently and we maybe hit 40-degrees with no snow on the ground, ticks can be active.”
A hidden gem on campus: Inside UW-Madison’s Zoological Museum
All that most students see of the University of Wisconsin Zoological Museum (UWZM), located in the Noland Zoology Building, is the fourth floor staircase’s sign prohibiting entrance from all other than museum staff.
Behind the locked doors, however, the museum’s extensive collections of animal skins and skeletons serve as a powerful resource for research and learning.
A UW-Madison researcher studied social media’s impact on teens. The Trump administration cut the grant.
The University of Wisconsin-Madison lost at least $12 million in federal research grants since the start of the Trump administration, forcing faculty and researchers to shut down projects, lay off staff and scale back scientific progress.
Dr. Ellen Selkie, an assistant professor at UW-Madison and principal investigator on a now-defunded National Institute of Health-funded study, said her team enrolled more than 325 adolescents from across Wisconsin and collected comprehensive data to explore a question they believed to be at the center of national concern: How does social media affect youth mental health?
UW-Madison professor predicts new tariffs will cost dairy farmers a quarter of their income
University of Wisconsin-Madison agriculture and economics professor Chuck Nicholson explained why the Trump administration’s recent tariffs will lower the price of milk while slashing incomes for American dairy farms, harshly impacting Wisconsin’s dairy industry.
Rising housing costs are forcing some Wisconsinites to delay medical care, new report says
Rising housing costs have been forcing some Wisconsinites to delay medical care, which can lead to negative health outcomes for residents and communities.
That’s according to a new report from the University of Wisconsin-Extension as part of a project examining livability in rural communities led by Tessa Conroy, associate professor of agricultural and applied economics at UW-Madison.
Envoys from UW-Madison CALS engage with dairy, crop industries in Thailand
When a Thai princess was looking to reinvigorate her country’s dairy industry, she quickly turned to the University of Wisconsin-Madison for help. The UW-College of Agricultural and Life Sciences answered her invitation with experts from the departments of animal and dairy sciences, and biological systems engineering. They, with financial support from Thailand, recently put their boots on the ground to start an exchange of ideas that will benefit both nations.

How your pets alter your immune system
According to Nasia Safdar, an infectious disease professor at the University of Wisconsin in the US, this concept has attracted interest from the pet food industry. The idea would be to develop products marketed as promoting the growth of beneficial bacteria in cats and dogs, which might then be transferred to their owners, she says.
“That angle has been an attractive one for people to fund, because for most of us, it’s the human condition that we’re interested in,” says Safdar. “So what role can the animal play in that?” she asks.
UW Health expert shares friendly family summer activities
While many kids will reach for screens, Dr. Shilagh Mirgain, a distinguished psychologist with UW Health, said this doesn’t have to be the default.
She suggests going to the library with your kids and having them check out books.
She also recommended parents take their kids to a local or state park, even going as far as planning a picnic. “Think about bringing your food outside to eat. Kids outside thrive,” she said.

Dane County health officials monitoring federal COVID vaccine limits
Dr. Dominique Brossard, chair of the Department of Life Sciences Communication at the University of Wisconsin-Madison, said social scientists are worried the federal policy changes could instill more distrust in science more broadly.
“My concern is that if you start with (existing distrust in science) and giving doubt about these specific vaccines … does that instill a doubt about all the vaccines? So, is it opening the door or building that hesitancy?” Brossard said. “The whole context is definitely breeding ground for doubt and that we need to closely watch.”
Wisconsin celebrates Dairy Month as state trade exports reached $8.2 billion last year
Chuck Nicholson is an associate professor of agriculture and economics at the University of Wisconsin-Madison. He said 20% of the milk produced ends up outside the U.S.
Nicholson said he doesn’t expect the dairy export market with China to be significantly impacted for the time being and that’s a good thing for Wisconsin.
“Cheese is definitely important as an export product, and it’s obviously quite important in Wisconsin. The other part about that is that with cheese typically comes whey, and we’re also a major exporter — from the State of Wisconsin — of whey products, and China is also a major market for our whey products as well,” Nicholson said.
Please, Democrats, just try to be normal
And Allison Prasch, an instructor at the University of Wisconsin at Madison, is quoted as saying that “Democrats trip over themselves in an attempt to say exactly the right thing.”
Nonsense. Some Democrats trip all over themselves trying to obscure the meaning of what they say. Take referring to felons as part of “justice-involved populations.” Likewise, the term “undocumented person” implies that the problem is one of paperwork. It simply omits the fact that the person resides in the United States illegally.

The University of Wisconsin-Madison Collaborative for Reproductive Equity released a study this spring showing that during the 13-month period in which abortion was largely unavailable in Wisconsin, OB-GYNs struggled to provide care for pregnant patients and treat pregnancy complications because of unclear legal guidelines.
A fungal disease ravaged North American bats. Now, researchers found a second species that suggests it could happen again
“Cave ecosystems are so fragile that if you start pulling on this thread, what else are you going to unravel that may create bigger problems in the cave system?” said University of Wisconsin–Madison wildlife specialist David Drake to the Badger Herald’s Kiran Mistry in December.
Hypogamy, the increasingly common romantic choice among brilliant women
Historically, hypergamy—when a woman marries a man of higher social or educational status—was the norm. However, this trend is gradually reversing. In the United States, according to sociologist Christine Schwartz of the University of Wisconsin, the proportion of couples where the woman is more highly educated than her partner increased from 39% in 1980 to 62% in 2020.
Will your car hit that deer? Depends on your headlight bulbs—and the deer’s personality
“It’s a really exciting area of research,” says John Orrock, a behavioral ecologist at the University of Wisconsin–Madison who was not involved in the study. “What’s key here is that it’s not whether you’ve got a deer in the headlights—and not so much even which headlights—but which deer you have in the headlights.”
Annette Zimmerman on AI data centers, jobs and the economy
UW-Madison political philosophy professor Annette Zimmerman considers economic motivations for locating AI data centers in Wisconsin and political conflict over how this industry can impact jobs.
The Wisconsin Supreme Court will soon make final ruling on abortion. How did we get here?
The 1849 law has been on hold since a lower court’s ruling in December 2023. The state then returned to its pre-Dobbs abortion laws, under which abortion is banned 20 weeks after “probable fertilization.”
“We’re just waiting for a final answer on that,” said Bryna Godar, a staff attorney with the State Democracy Research Initiative at the University of Wisconsin Law School. “The current state of the law has been that abortions are legal, subject to other laws we have in the state.”
Will you be able to get a COVID-19 shot? Here’s what we know so far
Together, the moves have left health experts, vaccine makers and insurers uncertain about what to advise and what comes next.
“It’s going to add a lot of confusion overall,” said Ajay Sethi, an epidemiologist at the University of Wisconsin-Madison.
Wisconsin Supreme Court suspends Dane County judge over ‘intemperate’ behavior
Although the process for handling judicial misconduct varies by state, it is “somewhat rare” for judges to be suspended in Wisconsin and across the nation, said Bryna Godar, a staff attorney at the State Democracy Research Initiative at the University of Wisconsin Law School.
“[Nationwide] the overall judicial disciplinary process is sometimes critiqued from both sides as being overly lenient on judges or as being too harsh on judges,” Godar said. “It’s really difficult to strike this balance between accountability for judicial officers while wanting to preserve the independence of state courts and state judges.”
Dog park etiquette, Being a veterinarian
With more American households now having pets than children, demand for veterinarians is on the rise. Citing an increase for veterinarian job listings of 124 percent over the last three years, the employment website Indeed this year named being a vet their top job of 2025. We talk with veterinarian and clinical instructor Dr. Calico Schmidt of the UW-Madison School of Veterinary Medicine about the joys and challenges of making a living caring for animals.
UW-Madison center sees promise in using psychedelics for addiction, PTSD, depression
The UW–Madison Transdisciplinary Center for Research in Psychoactive Substances supports research and education into psychedelic drugs and related compounds. The idea is to learn how these psychedelic substances may help mood or behavior in ways other forms of therapy can sometimes fall short.
For the last 10 years, the center at UW-Madison has been part of a psychedelic renaissance in the science community, one that comes after decades of negative media attention stymied research and public perceptions.
We’re getting close to recreating the first step in evolution of life
“RNA nucleotide triplets serve very specific informatic functions in translation in all cells,” says Zachary Adam at the University of Wisconsin-Madison, meaning they are used to convey information. “This paper is interesting because it might point to a purely chemical role – a non-informatic function – for RNA nucleotide triplets that they could have served prior to the emergence of a living cell.”
UW-Madison researcher discovers valuable chemical compound in engineered poplar trees
A UW-Madison researcher has made a surprising discovery that could transform how we source important chemical compounds used in everyday products, moving from fossil fuels to trees.
Brian Fox, a biochemistry professor at the University of Wisconsin-Madison, has identified parahydroxybenzoate—a chemical compound used in medicine, cosmetics, and food products that’s normally taken from oil—in biochemically engineered poplar trees.
After becoming fixture of Monroe Street, beloved ‘Madison Mural’ to come down
Local artist Liubov Szwako, better known as “Triangulador,” and University of Wisconsin-Madison graphic design lecturer Henrique Nardi were commissioned by the owner of Lauer Realty to transform the blank wall.
The internet is littered with advice. What’s it doing to your brain?
“Research has overwhelmingly found that advice is really beneficial, and that people tend to under-utilize advice, usually causing them to make lower quality decisions,” says Lyn van Swol, a professor of communication science at the University of Wisconsin-Madison who studies advice and information-sharing in groups. The catch, she notes, is that most of that research looks at advice from one, two, or three other people, not dozens, hundreds, or thousands of strangers on TikTok: “It’s overwhelming — it’s like a fire hose of advice.”
Five years after George Floyd’s death, why misinformation still persists
“The core through-line that emerges is the kind of longstanding, deep racist narratives around Black criminality and also the ways people try to justify who is or isn’t an ‘innocent victim’,” Rachel Kuo, a University of Wisconsin-Madison professor who studies race, social movements and technology, said of the falsehoods.
Scientists have lost their jobs or grants in US cuts. Foreign universities want to hire them
Brandon Coventry never thought he would consider a scientific career outside the United States. But federal funding cuts and questions over whether new grants will materialize have left him unsure. While reluctant to leave his family and friends, he’s applied to faculty positions in Canada and France.
“I’ve never wanted to necessarily leave the United States, but this is a serious contender for me,” said Coventry, who is a postdoctoral fellow studying neural implants at the University of Wisconsin-Madison.
‘It does kind of make me the breadwinner’: stay-at-home mom charges husband $2,700 a week for household labor — sparking a debate on TikTok
Of course, not every household follows the traditional gender roles. But data from the University of Wisconsin-Madison finds that women still spend twice as many hours doing physical housework as their male partners.
It doesn’t stop there. Allison Daminger, an assistant professor of sociology, found in her research that in 80% of opposite-sex couples, women shoulder most of the cognitive labor — things like managing family calendars, planning meals and checking on homework.
Democratic troubles revive debate over left-wing buzzwords
Honestly, Democrats trip over themselves in an attempt to say exactly the right thing,” said Allison Prasch, who teaches rhetoric, politics and culture at the University of Wisconsin at Madison. “Republicans maybe aren’t so concerned about saying exactly the right thing, so it may appear more authentic to some voters.”
She added: “Republicans have a willingness to paint with very broad brushstrokes, where Democrats are more concerned with articulating multiple perspectives. And, because of that, they can be hampered by the words and phrases they utilize.”
The curse of Toumaï: an ancient skull, a disputed femur and a bitter feud over humanity’s origins
Macchiarelli now brokered the publication of two of them on the widely read blog of John Hawks, a University of Wisconsin-Madison professor and longtime Sahelanthropus sceptic. In principle, to print images of someone else’s unpublished fossil was a clear breach of ethics. But then, Macchiarelli, Bergeret and Hawks reasoned, after Beauvilain’s article, the femur was no longer unpublished.
5 myths about food expiration dates and best-by labels
Kathy Glass, who recently retired as associate director at the Food Research Institute at the University of Wisconsin at Madison, said she respects “use-by” dates and other storage guidance (like an ideal fridge temperature) on refrigerated products, particularly those designed to be eaten cold.
“Many manufacturers have researched spoilage versus safety to determine those dates,” she said. On those keep-cold products, she said the phrase “use by” signals “they’ve done their studies to demonstrate that if you would use it by that particular date, and you kept it at a good refrigeration temperature, it should be safe.” Food should be refrigerated between 35 and 40 degrees, she said.
An ominous green sky is often associated with severe weather, but not every storm causes the sky to change colors.
Scientists aren’t completely sure why some intense thunderstorms turn the sky green, but research meteorologist Scott Bachmeier at University of Wisconsin-Madison says it could be linked to two factors: the color of the sky late in the day and the amount of rain in the storm.

“It’s an audacious paper but, using just the contact lens, you wouldn’t be able to read a book in the infrared, or navigate down a dark road,” says Mikhail Kats at the University of Wisconsin-Madison, who was not involved in the research.
This simple diet change can add decades to life expectancy, study finds
“Different components of your diet have value and impact beyond their function as a calorie,” said Dudley Lamming, a metabolism expert from the University of Wisconsin who is involved in both studies. “We’ve been digging in on one component that many people may be eating too much of.”
