We often treat paternity leave like a company perk—something HR lists next to the gym stipend and the 401k match. The research says we are wrong about that categorization. Paternity leave should be part of routine medical care during this stage of life: interventions we already agree are worth investing in because the return on investment continues years later in a child’s brain.

A chemical produced by gut bacteria may accelerate Alzheimer’s disease
A byproduct produced by certain gut bacteria may directly accelerate the brain changes associated with Alzheimer’s disease. Elevated blood levels of this molecule, known as imidazole propionate, correlate with worse cognitive decline in humans and actively drive neurodegeneration in animal models. The findings were published in Nature Communications.
Researcher who listens to forests wins 2026 Pritzker Environmental Genius Award
“Receiving this award feels really humbling, and also special, maybe particularly so during times that are challenging for work in environmental issues and conservation,” Burivalova told Mongabay by email. “I see getting an award like this to also mean taking the responsibility for doing as much as I can for biodiversity conservation in the years to come.”
An associate professor at the University of Wisconsin–Madison, U.S., and the principal investigator of the Sound Forest Lab, Burivalova has worked in forests across the world, including Papua New Guinea, Indonesia, Peru, Madagascar, and Ecuador.

Your Ferns Are Starting to Yellow—Here’s When to Cut Them Back and When You Should Leave Them Alone
Ferns come in many varieties, and most fern fronds will develop a yellow-gold hue in the fall, just like many other trees and plants in your yard.
“It’s a very normal and often welcome part of the changing of seasons,” horticulturist and garden designer Grace Coburn says.
However, if your fern develops too many yellow fronds too quickly—or you see webbing, sticky residue, or stippling on leaves in addition—it might be cause for concern. Here’s what pro horticulturists say you should know when your fern starts yellowing.

UW puts Wisconsin at the forefront of science | Our view
Scientific discovery takes a lot more than smarts. It often requires the audacity to think big, take chances and convince others to commit decades of time and millions of dollars.
That’s what UW-Madison professor Francis Halzen and his team did in spectacular ways, winning the Nobel Prize for physics last week. All of Wisconsin should be proud of his hard work, adventurous mind and the window he built into the universe at the bottom of the Earth.

How do we connect extreme weather events to climate change?
Question: How do we know if an extreme weather event is due to our changing climate?
Answer: Weather events result from an interaction of many factors, including current conditions of the atmosphere. Weather is considered extreme when it’s far outside of normal for a particular place and time. Weather-related extreme events include heat waves, freezes, heavy downpours and tornadoes. Attributing an extreme weather event to the observed climate change is referred to as the science of extreme event attribution.
‘Here & Now’ Highlights: Michael Wagner, Chief Justice Jill Karofsky
- Social media is rife with disinformation during the2026 election season. New and easy-to-use artificial intelligence tools can put real-sounding words in candidates’ mouths alongside possibly convincing video manipulation. In Wisconsin’s 3rd Congressional District race, Democratic candidate Rebecca Cooke responded by sending a cease-and-desist letter to Republican incumbent U.S. Rep. Derrick Van Orden for his use of AI to generate video making it look like she was saying things she did not actually say. Wagner said it’s a confusing landscape for voters.
