Researchers from the University of Wisconsin–Madison and the University of Florida led the project, working with colleagues at the University of Sydney, the University of Minnesota Twin Cities, Victoria University of Wellington, and the University of Massachusetts Amherst.

“This is not good news for us as we head into the future,” said Andrea Dutton, a professor of geoscience at Wisconsin.

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.

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.”

“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.

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.

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.

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 In principle, to print images of someone else’s unpublished fossil was a clear breach of ethics.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.

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.

“Coastal communities that are adapting to and preparing for future sea-level rise are largely adapting to the amount of sea-level rise that has already occurred,” said co-author Andrea Dutton, a geoscientist and sea level expert at the University of Wisconsin–Madison. In a best-case scenario, she added, they are preparing for sea level rise at the current rate of a few millimeters per year, while the research suggests that rate will double within decades.

The analysis is largely in line with the findings of Wisconsin’s Initiative on Climate Change Impacts, according to Jonathan Patz, a professor in the Nelson Institute for Environmental Studies and Population Health Sciences at the University of Wisconsin-Madison.

“We’re seeing more nighttime warming than daytime warming, which is a problem for health,” Patz said. “Because if you don’t have cooling temperatures in the nighttime, it’s more dangerous, and there are more people at risk from heat waves.”

“Every fraction of a degree matters,” said Andrea Dutton, a research professor at the University of Wisconsin at Madison, who was a co-author of the study. “We can’t just adapt to this type of sea-level rise. We can’t just engineer our way out of this.”

Professor Andrea Dutton of the University of Wisconsin-Madison, who was part of the study team, said: “Evidence recovered from past warm periods suggests that several metres of sea level rise – or more – can be expected when global mean temperature reaches 1.5C or higher.”

Chris Vagasky explains how reduced weather balloon launches and staffing shortages at the National Weather Service may compromise the ability to predict dangerous weather events.

“There are always midges coming out of the lakes, but most people don’t really notice them because they’re not very abundant. So it’s not really on the radar,” said Jake Vander Zanden, who studies the biology of lakes as chair of the Center for Limnology at the University of Wisconsin-Madison.

“It is truly the pinch point. It is the one place where you have a large canal that connects the two,” said Jake Vander Zanden, who directs the University of Wisconsin-Madison Center for Limnology.
