AI Fails to Grasp Populism’s Nuances: Trump’s Rhetoric Reveals AI’s Limits

Can artificial intelligence truly understand the subtleties of human politics? A new study from the University of Copenhagen, led by Ilias Chalkidis, Stephanie Brandl, and Paris Aslanidis, throws cold water on that idea. Their research delves into the surprisingly complex task of using AI to identify populism in political speech, revealing unexpected limitations in even…

Do Quantum Tricks Make City SMS Forecasts More Clever?

Background: the city’s pulse and the lure of quantum thinking Cities don’t speak in neat, tidy plots. They buzz with hundreds of tiny rhythms: mass transit kicking into gear, cafe lines swelling on sunny afternoons, crowds dissolving into evening quiet as people drift home. Telecommunication signals—SMS bursts, call bursts, data pings—are a kind of urban…

A Hidden Rule Links Four Points to Perfect Data Codes

The world of mathematics isn’t just chalk on a board; it’s a treasure map for how we store, share, and understand information. In a new line of thought, a researcher named Stanislav Semenov sketches a simple, almost shy rule—a four-point invariant—that binds four consecutive evaluations of a sequence into a single, unchanging truth. It’s the…

How Many Trees Can Share at Least ‘t’ Branches?

Unraveling the Intersections of Spanning Trees Imagine a sprawling network, a complete graph where every node is connected to every other node. Now, picture all the possible spanning trees within this network – each a skeleton of connections, reaching every point without any cycles. A new mathematical result, emerging from the University of Minnesota Duluth,…

Counting crowds gets a softer, smarter nudge

Counting people in a photo isn’t just a nerdy puzzle; it’s a real‑world skein of tiny decisions: who counts, who’s occluded, where a group ends and a stray limb begins. For years, researchers trained counting systems with a blunt signal: either the count was right, or it wasn’t. But in messy scenes—dense crowds, shifting light,…

Lego, Phones, and the Secret Language of Waves

Forget expensive labs and complicated simulations. Researchers at University College Dublin, led by Lennon Ó Náraigh, Nicolas Farault, and Nicola Young, have shown that you can unlock the mysteries of water waves using surprisingly simple tools: a tabletop flume built from Lego, a smartphone, and some clever software. The Unexpected Elegance of Simplicity The study,…

When Radar Becomes a Heartbeat Whisperer

Listening to the Heart Without Touching It What if your heart could be monitored without a single electrode stuck to your skin or a smartwatch strapped to your wrist? Researchers at Xi’an Jiaotong-Liverpool University and their collaborators have been exploring a fascinating frontier: using radar waves to eavesdrop on the subtle vibrations of your heartbeat…

Calibrated 3D maps bloom from random starts

In the world of computer vision, turning a handful of photos into a believable map of the world is like assembling a city skyline from silhouettes. The problem is not just about finding where all the buildings stand, but about knowing what the buildings’ sizes and angles really are. If you don’t know exactly how…

Tiny Blocks Teach AI to See in 6D Classrooms

Intro In classrooms where students turn physical objects into ideas, the best kind of teaching avoids turning learning into a game of buzzwords and screens. It’s the kind of learning that happens when hands meet hardware and questions meet curiosity. A team from Colorado State University has pushed a new boundary in this space by…
