The Comet Strike Theory That Just Won’t Die

The New York Times

When the paper came out, Jacquelyn Gill was working on her dissertation at the University of Wisconsin, Madison, studying the Pleistocene mammal populations of the Upper Midwest through the proxies of ancient pollen, charcoal and fungal spores.

‘I am a champion for growing Milwaukee’: Takeaways from Cavalier Johnson’s State of the City address

Milwaukee Journal Sentinel

His comments included a reference to a city plan that prioritizes lead service line replacement based most heavily on the area deprivation index, which ranks neighborhoods by “disadvantaged status,” according to the Center for Disparities Research at the University of Wisconsin School of Medicine and Public Health.

Trump’s claims of a migrant crime wave are not supported by national data

NBC News

The data is incomplete on how many crimes each year are committed by migrants, primarily because most local police don’t record immigration status when they make arrests. But the studies that have been done on this, most recently by the University of Wisconsin-Madison, show that in Texas, where police do record immigration status, migrants commit fewer crimes per capita.

My friend’s husband pressured her to give up her job — and ‘lost’ her passport

MarketWatch

Coercive control and financial abuse are often tied together. The vast majority of domestic-abuse cases also involve economic abuse, and finances are one of the main reasons a person stays with or returns to an abusive partner, as noted in a research brief by the University of Wisconsin-Madison Center for Financial Security. The fact that your friend’s husband pushed her to give up her job is a bad sign.

The truth about illegal immigration and crime

The Washington Post

“Many politicians, law enforcement personnel and ordinary citizens are nonetheless incensed because this person should not have been in the country and thus capable of committing a crime,” said Michael Light, a sociologist at the University of Wisconsin at Madison who has published several studies showing undocumented immigrants are not more crime-prone than native-born Americans. “This view that the person’s undocumented status is an aggravating factor is also likely a reason why these crimes generate such strong responses.”

Study shows warming waters affecting reproduction of walleye in Upper Midwest lakes

Wisconsin State Journal

A study from a UW-Madison researcher published Monday in the journal Limnology and Oceanography Letters contends that walleye, one of Wisconsin’s most sought-after fish and one of its tastiest, are not only struggling to survive in warming waters; their reproduction is also being interfered with and has been “unable to keep up with increasingly early and more variable ice-off dates.”

Smith: On its 75th anniversary, lessons of “A Sand County Almanac” more relevant than ever

Milwaukee Journal Sentinel

Leopold, born in Iowa in 1887, received a forestry degree from Yale and began his professional career in 1909 with the U.S. Forest Service. In 1924 he became associate director of the Forest Products Laboratory in Madison and in 1933 the University of Wisconsin created a chair of game management for him. Leopold died in 1948 fighting a grass fire on a neighbor’s farm. The property is now part of the Aldo Leopold Foundation near Baraboo.

Is the 100-year old TB vaccine a new weapon against Alzheimer’s?

The Guardian

A pilot study by Coad Thomas Dow of the University of Wisconsin-Madison and his colleagues suggests that BCG injections can effectively reduce plasma amyloid levels, particularly among those carrying the gene variants associated with a higher risk of Alzheimer’s. Although the sample size was small – just 49 participants in total – it has bolstered hopes that immune training will be an effective strategy for fighting the disease.

Wisconsin Democrats talk a lot about Child Care Counts. But what is it?

Appleton Post-Crescent

A study by the University of Wisconsin-Madison Institute for Research on Poverty found the most commonly reported use of Program A funding among providers participating in the study is for physical operating expenses, such as rent and utilities. This was followed by materials and supplies for enhancing the program and then payroll and benefits.

UW-Madison’s Big Bet on AI

City Cast Madison

Podcast interview with Provost Charles Isbell: As one of the leading research universities in the country, UW-Madison marshals more than a billion dollars in research money annually. And the way Provost Charles Isbell sees it, the university’s scale and its public service mission makes it the perfect place to be at the forefront of the country’s artificial intelligence (AI) revolution, where computer systems are emulating human cognition.

Smith: Legislators propose UW study on effects of wake surfing on Wisconsin lakes

Milwaukee Journal Sentinel

With a pro-boating industry bill apparently dead in the Legislature and after a more lake-protective proposal failed to muster support among the Republican caucus, the prospect is dim for any new, statewide wake surfing law to take effect this year in Wisconsin.

But a measure to bolster the science of the impacts of wake-enhanced boating could garner more favor. A proposal announced Tuesday by Republicans would task the University of Wisconsin System with conducting a study on the effects of wake boating.

Colleges counteract a lack of public confidence in higher education with outreach

NPR

ELDER-CONNORS: UVM isn’t the only college doing this. Auburn University in Alabama and the University of Wisconsin received money from the same federal program that funds UVM’s work. Glenda Gillaspy at the University of Wisconsin says they’re setting up weather stations to help cranberry farmers time their harvests, which involves flooding their fields.

Wisconsin parents of young kids more likely to struggle with bills

The Capital Times

Conducted by the UW Survey Center and analyzed by UW-Madison’s La Follette School of Public Affairs, the survey went to around 3,500 people across the state. Researchers compared the responses of participants who have children under age 6 with those who don’t.

None of those findings are really “huge surprises,” said La Follette School professor Sarah Halpern-Meekin, who analyzed the results.

This Is Your Brain on 3-D Printing

Wall Street Journal

But then the journal Cell Stem Cell—always on my nightstand—reported that scientists at the University of Wisconsin had not only perfected a way to create brain tissue this way but could create brain cells that mimicked the behavior of real ones, and I knew that the breakthrough was real. Kudos to the Badger State scientists for figuring out that arranging the printed brain cells side by side, like a row of stick pretzels or a batch of linguine, would allow neurons to communicate just like those in a conventional brain.

Wisconsin on track to have warmest winter ever recorded

Wisconsin Public Radio

Steve Vavrus, a senior scientist at UW-Madison and the state’s climatologist, said the weather is already causing economic impact, especially on the tourism industry in northern Wisconsin.

“They depend on snow and ice for skiing and skating and ice fishing and so forth,” Vavrus said.  “There’s been closed snowmobile trails. There’s been winter festivals that have been canceled, unsafe ice conditions for fishing and so on.”

Valentines for your dog? It’s one way we treat pets like family

Milwaukee Journal Sentinel

Valentine’s Day reminds us to show our love to the important people in our lives. We usually declare our romantic love, but sometimes all the hearts and flowers remind us to express our love to others who are important in our lives as well. For a lot of us, this could mean our dogs. About half of U.S. households keep dogs as pets. Not only in word, but also in deed, many people express their love for their dogs not merely as pets, but as family.

Written by David L. Weimer is the Edwin E. Witte Professor of Political Economy at the University of Wisconsin–Madison. He is coauthor with Aidan R. Vining of “Dog Economics: Perspectives on Our Canine Relationships” (Cambridge University Press 2024).

Parts of Wisconsin will be a lot louder this summer. The culprit? Cicadas

Wisconsin Public Radio

The sounds of summer could be a lot louder this year depending on where you live in Wisconsin.

That’s because for the first time since Thomas Jefferson was president, two rare broods of cicadas will emerge at the same time. PJ Liesch, an extension entomologist at the University of Wisconsin-Madison, said this event only occurs once every 221 years. “It’s something that is really unique and special for us,” Liesch said.

UW professor is on a mission to grow a better-tasting beet

Milwaukee Journal Sentinel

Whether you love beets or hate them, you probably haven’t given them as much thought as Irwin Goldman.

A professor at the University of Wisconsin-Madison, Goldman is also former chair of the department of horticulture. The Goldman Lab there is even named after him. He and colleague Nick Breitbach spent decades trying to breed a better beet. Now the Badger Flame Beet is getting attention nationwide from growers and chefs as it becomes increasingly available.

Sad tomatoes in space: Wisconsin scientists develop TASTIE experiment to grow plants without gravity

Wisconsin Public Radio

From the care of Wisconsin researchers to the International Space Station, a group of tomato plants rode on a rocket last week with the goal of brightening astronauts’ days — and their diets. But first the tomatoes are trying to find their own joy.

Growing without gravity is stressful to tomatoes, said Simon Gilroy, a University of Wisconsin-Madison botanist who runs a lab that studies plant development.

Scientists have 3D bioprinted functioning human brain tissue

Popular Science

As detailed in the new issue of the journal Cell Stem Cell, University of Wisconsin-Madison researchers have developed a novel 3D-printing approach for creating cultures that grow and operate similar to brain tissue. While traditional 3D-printing involves layering “bio-ink” vertically like a cake, the team instead tasked their machine to print horizontally, as if playing dominoes.

Space tomatoes, Hanging out, RSV explained, Struggling US parents

Wisconsin Public Radio

We learn about a UW connection to experimenting with growing tomatoes beyond Earth’s atmosphere. Next we talk about the art of doing nothing in particular. Then we hear what to know about the rise of the respiratory virus RSV. And we explore the problems American parents face compared with those in other countries. Interviews with Simon Gilroy and Dr. James Conway.

UW-Madison researchers uncover hint for cause of cleft lips and palates in developing babies

Wisconsin Public Radio

Researchers at the University of Wisconsin-Madison are one step closer to understanding how and when cleft lip and palates form during pregnancy.

The discovery, recently published in the Proceedings of the National Academy of Sciences, could mitigate the risk of the birth defect that affects about 1 in every 1,700 babies born in the United States.

What is Wisconsin’s minimum wage, and why hasn’t it changed when other states’ minimum wages have?

Milwaukee Journal Sentinel

Low-wage workers have found it especially hard to afford higher housing costs, even before a spike in prices in 2022, explained Laura Dresser, associate director of the High Road Strategy Center (formerly COWS, a left-leaning think tank) at the University of Wisconsin-Madison.

Dresser’s research has found that increasing the minimum wage to $15 over the next five years would increase wages for one in seven workers in Wisconsin. That includes one of every four Black and Hispanic workers.

Air sampling in Dane County schools tracks flu, COVID-19

Wisconsin State Journal

“It can tell us about the virus without us needing to stick anything up anyone’s noses or even know who was in a space,” said Dave O’Connor, a UW-Madison researcher involved in the surveillance. “Air sampling should be something that lots of schools bring on board to understand what the respiratory virus transmission risk is.”

Monitors have been at seven schools in the Oregon School District for two years, where air sampling last school year tracked flu and COVID-19 activity as reliably as student absences, rapid tests at school and regular tests from samples collected at home, UW-Madison researchers recently reported. That research was part of a UW study, funded by the Centers for Disease Control and Prevention, that has analyzed respiratory illness at Oregon schools since 2015.

Can groundhogs or other animals predict the weather?

CNN

“One example is planting corn when oak leaves are the size of a squirrel’s ear,” notes an article on phenology from the University of Wisconsin-Madison. “You know that planting corn has nothing to do with oak leaves or squirrels. However, Native Americans made the observation centuries ago that the soil was warm enough to prevent seeds from rotting, yet it was still early enough to reap a suitable harvest if corn was planted at this time.”

First 3D-printed functional human brain tissue grows like the real thing

New Atlas

University of Wisconsin–Madison (UW-Madison) researchers have successfully 3D-printed brain tissue that grows and functions like a typical brain.“This could be a hugely powerful model to help us understand how brain cells and parts of the brain communicate in humans,” said Su-Chun Zhang, the study’s corresponding author. “It could change the way we look at stem cell biology, neuroscience and the pathogenesis of many neurological and psychiatric disorders.”

National Alzheimer’s research led by UW-Madison boosted by $150M grant

Wisconsin Public Radio

The grant from the National Institutes of Health will fund neuroimaging, particularly PET scans, to better understand Alzheimer’s and other dementias in living people. The hope is that by identifying how Alzheimer’s affects the brain, future researchers will be able to eventually prevent, slow or delay the onset of the disease and better treat its symptoms.

With deep roots in Wisconsin, Carbone Cancer Center does vital work

Wisconsin State Journal

Near the start of a Jan. 23 presentation by the director of Wisconsin’s signature cancer research center, I asked those attending how many had family members who had been touched by the disease over time. Nearly every hand in the room went up.

That speaks to the insidious nature of a disease that in some ways remains a mystery to researchers such as those who work at UW-Madison’s Carbone Cancer Center. It also illustrates the need for continued progress in finding better approaches to prevention, diagnosis and therapy surrounding one of mankind’s oldest scourges.

A high school wrestling evolution: Out with vomiting, in with hydration

The Washington Post

These habits can only lead to negative physiological and mental effects and also can make wrestling more dangerous. A University of Wisconsin study, published in 2022 in the British Journal of Sports Medicine, followed 67 Division I college wrestlers over seven seasons and found that a 1 percent loss in body weight correlated with an 11 percent higher chance of injury during competition.
