Spongy moth populations may spike temporarily about every 10 years. Outbreaks have been trending upward in the last couple of years, according to PJ Liesch, an entomologist with the Division of Extension at UW-Madison. The DNR recorded 294 acres of spongy moth defoliation in 2021, but around 85,000 acres of trees experienced a loss of leaves last year.

That could have to do with workers in service industries gravitating toward jobs that were more stable during the COVID-19 pandemic, said Nancy Wong, UW-Madison professor of consumer science.

“Perhaps these industries also do not pay as well,” she said, and salon owners are faced with the expense of raising wages and offering regular hours. That cost can be passed on to customers.

A panel of scientists are saying the planet is entering a new geologic epoch for the first time in civilization’s history: the Anthropocene. It’s also the first era sparked by humanity’s planetary impact. We talk with Elizabeth Hennessy, a UW-Madison Environmental Studies associate professor, about the effects of humanity on the planet. 

Jim Lattis, director of University of Wisconsin’s Space Place, said auroras are caused by charged particles from the sun interacting with gasses like nitrogen in the Earth’s atmosphere. He said a lot of things have to go right for that to happen.

“There are solar flares popping off on the sun every other day or daily these days, but those flares have to emit something that then crosses an awful lot of space between us and the sun, and then actually interacts with the earth,” he said.

John Gross, a law professor at the University of Wisconsin and the director of the Public Defender Project, said the special statute is often called “John Doe prosecution.” States with older laws, before elected prosecutor roles existed, required their laws to allow for a direct filing of criminal complaints by a citizen.

Timothy Smeeding, a labor economist and social welfare policy analyst at the University of Wisconsin-Madison La Follette School of Public Affairs, said the bill could bring up concerns if young people actually had to serve alcohol at the bar. However, he said that if they’re already serving food at a restaurant, allowing them to carry alcohol shouldn’t make a big difference.

Anuj Desai, a University of Wisconsin-Madison law professor who specializes in issues including free speech and statutory interpretation, agreed that those laws probably don’t apply to organizers or people responsible for children participating in the Naked Bike Ride.

“If the whole point (of the Naked Bike Ride) is that bodies are not sexual items, it’s not likely to satisfy a legal standard that requires it to be appealing to the prurient interest of children,” Desai said.

“The median loan payment in Wisconsin is $152 a month. So, it kind of gives a little bit of a sense of how big this is,” Nick Hillman, Professor of Educational Leadership & Policy Analysis at UW-Madison said. “So, what a quarter, one in four people you see walking down the street are now gonna have to pay probably about 150 a month that they haven’t been paying for the past few years.”
