Scientists finally have something hopeful to tell us about monarch butterflies

The new numbers are still way below the average from the first 10 years of monitoring (about 21 acres) and what scientists consider sustainable (about 15 acres). But they still amount to good news, said Karen Oberhauser, a professor emeritus at the University of Wisconsin-Madison, and one of the nation’s leading monarch experts.

“We are in a period of relative stability where the population has stopped declining,” Oberhauser, who was not involved in the new WWF Mexico report, told me.

Teens are sleeping less. Why schools should be worried

EducationWeek

Researchers from several prominent universities examined the self-reported sleep habits of nearly 130,000 teens. They found that the number of teens getting insufficient sleep, defined as seven hours or less a night, rose from 69% in 2007 to 78% in 2023, the most recent year for which data was available.

“We know that sleep plays a really critical role in adolescent brain development,” said Tanner Bommersbach, a child and adolescent psychiatrist and assistant professor of psychiatry at the University of Wisconsin-Madison and one of the authors of the study. “So when large numbers of teens aren’t getting enough sleep, it really raises concerns about the downstream effects that that could be having on their mental health, on their academic performance, on their engagement and risk behaviors.”

These sea slugs can ‘eat’ sunlight—but they’re no astrophage. Here’s how the ‘Project Hail Mary’ antagonist has a real-life analog in Earth’s oceans

According to Betül Kaçar, an astrobiologist at the University of Wisconsin-Madison, organisms developing the ability to “eat” radiation isn’t out of the realm of possibility—in fact, it has happened already on Earth.

“Life found a way to eat pretty much anything it can on this planet. It’s quite remarkable,” she says. “If you think about it, the fact that life can capture photons [or particles of light] is ‘eating radiation.’ … For many microbes, the photons are great resources of energy. So phototrophs are an example of radiation-eating organisms on this planet.” Plants are well-known phototrophs, but sea slugs are unexpected ones, making their ability to gain fuel from radiation just as remarkable as that of the Astrophage microbes.

Wisconsin Senate passes NIL bill that gives Badgers taxpayer funding

Milwaukee Journal Sentinel

The Wisconsin Badgers are one step closer to receiving taxpayer support as they adapt to the changing college sports landscape.

With a one-vote margin, the state Senate on March 17 approved a bill to provide taxpayer funding for athletic facility debt service and formalize rules around name, image and likeness. Eleven Republicans and six Democrats voted in favor of the bill, while seven Republicans and nine Democrats voted against it.
