University of Florida researchers are developing AI models that combine satellite imagery, GPS, LiDAR and environmental data to detect early warning signs of sinkholes.

The state’s limestone geology makes it especially vulnerable, with thousands of sinkholes reported each year and damages costing hundreds of millions annually.

The NSF-funded project aims to produce open-source software that predicts sinkhole risk, helping planners and communities make safer infrastructure decisions.

When cardiac arrest strikes, immediate CPR can double or even triple a person’s chance of survival—yet more than half of people who collapse outside a hospital don’t receive it. To help close that gap, the American Heart Association and the National Football League (NFL), along with Damar Hamlin’s Chasing M’s foundation and the most followed doctor on social media, Doctor Mike, will attempt the Guinness World Records® title for Most people to complete CPR training in one hour. The record will be set by training 4,000 people in Hands‑Only CPR in just one hour during.

Andrew Verdesca has been studying the aging process since he was an undergraduate. As one of the “few universal human experiences,” the biology of aging has always fascinated Verdesca, who is now a Ph.D. student in Yale’s Graduate School of Arts and Sciences.

“It’s one thing we all do,” says Verdesca, who is part of Josien van Wolfswinkel’s lab in Yale’s Department of Molecular, Cellular and Developmental Biology. “And yet we know so little about it.”

But new research from Verdesca, van Wolfskwinkel, and others offers fresh insights into our understanding of aging — including an unexpected twist. Contrary to popular belief, cellular “wear and tear” is not the only culprit behind age-related decline, they find. It turns out that a breakdown in the body’s “internal positioning system” — which directs cellular location — may play a significant role, too.

Their findings are published in the journal Current Biology.
