Hip-hop’s role in today’s classrooms
“The reason why it resonated with students … is because it felt like an opportunity for them to be met on their own ground and to have a kind of shared ground with which to meet instructors or meet ideas,” says Nate Marshall, award-winning poet and assistant professor of English at the University of Wisconsin-Madison. “Ultimately, like, the role of an educator is to connect the students in order to serve the students. So, if that’s not your way to connect with them, that’s cool. You find other ways.”

Hungry Japanese beetles are a formidable foe for Wisconsin vineyard owners
Christelle Guédot, a fruit crop entomologist and extension specialist in the Department of Entomology at the University of Wisconsin–Madison, says that Japanese beetles were once the bane of gardeners and farmers in the southern half of the state, but their range has since spread northwards.
“Over the past 10 years, they have been detected by the Wisconsin Department of Agriculture, Trade and Consumer Protection up in Bayfield. We also trap many hundreds in Spooner and we see them now in Door County,” Guédot said. The beetles have also been wreaking havoc in the northeastern counties, including Oneida and Vilas.

Felony AI-generated child porn case in Eau Claire County is a test of new Wisconsin law
Dietram Scheufele is a professor at the University of Wisconsin-Madison who specializes in misinformation, social media and AI. He told WPR the rise of artificial intelligence models has opened numerous legal and ethical questions that courts are left to grapple with.
On the technical side, Sheufele said, the question is how AI models are able to create lifelike images of child pornography. Another question is whether people or businesses that create the algorithm to assist the AI models that ultimately create the images would be liable.
“The same logic that applies to child pornography will apply to a whole bunch of other things — not in the sense of obscenity, but in the sense of responsibility and copyright, and all the other things that come that come along with that,” Scheufele said.
This wildfire season shows the limits of forest management in the face of climate change
Jack pine and black spruce trees fall into this category, according to David Mladenoff, professor emeritus at the University of Wisconsin-Madison. Both species reproduce by using cones that are sealed up with resin, and open to spread seeds only under the intense heat of a fire.
“The nature of the (jack pine and black spruce) trees — their foliage, their bark, they have a lot of resin — they burn easily. They kind of encourage fire because they need fire,” said Mladenoff.
China tech CEO reveals plans for humanoid ‘pregnancy robot’
“Pregnancy is an extremely complex process, with each step being extremely delicate and critical,” said Yi Fuxian, an obstetrician at the University of Wisconsin–Madison who conducts demographic research,

UW Extension is asking for help to identify spread of invasive plant
An invasive plant has been spotted in southcentral Wisconsin, and scientists are asking the public for help to prevent it from spreading across the region.
Japanese stiltgrass was spotted in Rock County last month.
Mark Renz, a University of Wisconsin–Madison Extension weed specialist and professor in the Department of Plant and Agroecosystem Sciences, said the grass is bad for a number of reasons.
Japanese stiltgrass is an annual grass, like crabgrass, that can grow in the woods.
“What it does is it produces a lot of fuel, and when that annual grass dies in the winter, that fuel persists, so it can increase the timeframe when fires naturally can occur in the forests,” said Mark Renz, a University of Wisconsin–Madison Extension weed specialist and professor in the Department of Plant and Agroecosystem Sciences.
In ancient teeth, clues of human evolution — and perhaps a new species
John Hawks, a paleoanthropologist at the University of Wisconsin-Madison who was not involved in the work, said the find is exciting because it opens a window into a critical and mysterious period of human evolution between 2.5 million and 3 million years ago. He said he’s eager to see the work published but noted that such finds raise as many questions as they answer.

A look at Wisconsin’s congressional districts, as Texas Republicans push to redraw their map
“If the state legislative districts were so gerrymandered that they violated the Wisconsin State Constitution, then the same is true of the congressional districts… Legally, the case is straightforward,” said Howard Schweber, affiliate faculty at the University of Wisconsin Law School.
West Point and Air Force Academy affirmative action lawsuits are dropped
The secretary of defense, Pete Hegseth, has long argued — first as a cable news host and then in his current position — that “woke” policies undermine morale in the military. But some who have studied military history disagree with that assertion.
“Nothing in my nearly 25 years of experience in the military substantiates that argument,” said John W. Hall, a professor of military history at the University of Wisconsin-Madison.
Dr. Hall, a 1994 West Point graduate, said that the military had been an early champion of diversity initiatives, “not out of any sense of innate progressivism or certainly not wokeness.” Rather, he said, “they were necessary for the effectiveness of the military.”
Dispelling the myths about MRNA

BLS nominee made claim that no ‘sensible economist would use’ — and that’s one of the kinder comments about him
Menzie Chinn, a professor of public affairs and economics at the University of Wisconsin–Madison and a research associate with the National Bureau of Economic Research, reviewed the claims and found them wanting.
“The conclusion that real GDP is lower as of 2024Q2 than it was in 2019Q1 is not backed up by any calculation using defensible deflators a sensible economist would use. Second, other non-deflator sensitive indicators of real economic activity do not exhibit a downward decline from 2022 onward,” Chinn said.
How Dane County, UW-Madison have prepared for potential measles outbreak
Jake Baggott, UW-Madison associate vice chancellor and executive director of University Health Services, said in a statement that UW-Madison as a campus has been actively preparing over the last year for a potential measles case.
University Health Services led and coordinated a walkthrough exercise with campus, local and state public health officials to simulate their preparedness during a measles outbreak, Baggott said
Madison rents up 47% over the last five years
Kurt Paulsen, a UW-Madison professor who studies urban development and housing policy, says the region’s high rents and low vacancy rates spurred developers to build more housing: “We have had a lot of supply come online in the last year, and a lot in the pipeline in the last year. And you see that now in the fact that the vacancy rate has shot up.”
Still, Paulsen cautions that new construction will likely slow down as developers wait for these units to be absorbed into the market. High interest rates and tariffs on construction materials — the U.S. Department of Commerce recently announced it is tripling duties on Canadian lumber to 21% — pushed by the Trump administration are also likely to slow construction. And though rent growth has stagnated, Madison’s high prices are still pricing out many potential residents.

Tech industry job tremors and AI boom propel changes at Wisconsin’s colleges
When Bill Zhu started a computer science major at the University of Wisconsin-Madison in 2021, he had no expectation the tech job market would dip, or would dip so soon. Over the previous decade, computer science became one of the most popular majors for new college students.
Why a UW-Madison ‘treasure trove’ of health data could go away
Fifteen years ago, the Population Health Institute at the University of Wisconsin-Madison launched the County Health Rankings and Roadmaps. The resource provides a “treasure trove” of public data and offers a snapshot on the health of nearly every county in the nation, said Sheri Johnson, the institute’s director.
While more than 700,000 people use the resource each year, Johnson said, County Health Rankings and Roadmaps will soon lose its primary funder. The New Jersey-based Robert Wood Johnson Foundation is set to end its support after 2026.
‘There’s gonna be some pain in the meantime’: Wisconsin farmers react to tariffs
