America is retiring coal plants slowly and steadily. The boilers are cut up for scrap, the smokestacks get dropped on camera and the land tends to sit in permitting limbo for a decade. But in Becker, Minnesota, the state’s biggest coal plant is being used, not for all this hardware but for a plug.On July…
Concrete is the most widely used manufactured material on Earth, yet most people only ever encounter it once it has already hardened into a wall, a road or a slab. Science communicator Derek Muller set out to understand what the material actually does while it is still wet, by climbing into a tank of fresh…
Image(s): Florida Key Isaland/Canva Imagine erasing almost every insect and small animal from an island, then watching nature rebuild itself from scratch. That was exactly what a team of ecologists did in the Florida Keys during one of the most influential ecological experiments ever conducted. In 1966, researchers enclosed tiny mangrove islands in enormous plastic…
The spotted lanternfly has become one of the most destructive invasive insects in the United States, threatening vineyards, orchards and forests by feeding on the sap of hundreds of plant species. Finding its egg masses before they hatch is one of the most effective ways to slow its spread, but the eggs are well camouflaged…
The Pacific Ring of Fire, the horseshoe-shaped belt of volcanoes circling the Pacific Ocean, may have played a far bigger role in shaping Earth’s past climate than previously understood. Findings show that some of the largest volcanic eruptions of the past 12,000 years, many originating from this seismically active region, align closely with major glacial…
The fossil record has a habit of reshaping ideas that once seemed settled. In the Late Cretaceous, long before the extinction of the dinosaurs, small mammals occupied a world dominated by much larger reptiles. Most left behind little more than isolated teeth and fragments of bone, making it difficult to understand how they were related…
Richard Feynman’s most enduring quote was never intended as a memorable slogan. It came from his 1974 commencement address at the California Institute of Technology, where the Nobel Prize-winning physicist spoke about the principles that should guide scientific research. Among his remarks, one sentence has outlived the rest: “The first principle is that you must…
“The present is theirs; the future, for which I really worked, is mine.” — Nikola Tesla (AI-generated image) Two inventors can watch someone else take credit for their work in real time and respond in completely different ways. One spends what energy remains fighting for immediate recognition, determined to win the argument before it’s too…
Representative Image of Europa’s hidden ocean beneath its icy surface (AI-generated image) Europa, one of Jupiter’s icy moons, may hold more liquid water than all of Earth’s oceans combined, sealed beneath a thick shell of ice. For years, one of the most promising ideas for studying that hidden ocean was that water rising through cracks…
Rewilded elephants on Khamab Kalahari Reserve, who were observed during this research project (from left to right: Ngwedi, Mana, Michael, and Chikwenya) South Africa released 11 elephants that had spent years in captivity into protected reserves. Five years later, researchers found that their behavior was very similar to elephants that had always lived in the…
