Scientists have uncovered a surprising second type of lion roar, using AI to decode vocal signatures with remarkable precision. This breakthrough sheds new light on how lions communicate and offers a powerful new tool for conservationists racing to protect shrinking populations.
The surprising reason bees replace their queens
Worker bees stage coordinated revolts when viral infections weaken their queen and lower her pheromone output. This disruption drives many of the queen failures that beekeepers struggle with today. Field trials show that synthetic pheromone blends can prevent untimely supersedure, opening a path to more stable hive management.
Rapid fault healing could rewrite earthquake physics
Scientists discovered that deep earthquake faults can heal far faster than expected, sometimes within hours. Slow slip events in Cascadia reveal repeated fault movements that only make sense if the fault quickly regains strength. Lab experiments show that mineral grains can weld together under intense heat and pressure, acting like...
Fossils reveal a massive shark that ruled Australia in dinosaur times
Around 115 million years ago, northern Australia’s seas hosted a colossal shark that rewrites what we thought we knew about early ocean predators. New fossil discoveries show that modern-type sharks were experimenting with gigantic sizes far earlier than scientists believed, competing with the marine “monsters” of the dinosaur age.
The mystery of volcanoes that don’t explode finally has an answer
Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles when pressure drops—it can do so simply by being sheared and “kneaded” inside a volcano’s conduit. These shear forces can trigger early bubble growth, create escape channels for gas, and sometimes turn...
Oral Arginine Reduces Amyloid Buildup in Alzheimer’s Models
Alzheimer's disease (AD), a progressive neurodegenerative disorder, is one of the leading causes of dementia worldwide, and currently has no definitive cure.
Quantum Calculations Expose Hidden Chemistry of Ice
The new theoretical research by UChicago PME and ICTP researchers has implications for melting permafrost and climate change.
Monsoon Storms Will Bring Heavier Rains but Become Weaker
Climate change will make monsoon storms in South Asia wetter and weaker, with more storms pushing further inland across India.
New European Service Will Investigate Role of Warming in Weather Disasters
A new E.U. service will determine how warming is reshaping weather. Its findings, experts say, could help insurers better understand climate risks and help advocates hold polluters accountable for climate damages.
This UW-Madison Spinoff is Making Environmentally-Friendly Cement. The Secret Ingredient is Pollution
Taken individually, coal ash and excess carbon dioxide are harmful pollutants. Combined in just the right way, they form a durable, inexpensive, and environmentally friendly building material.
