Uniaxial strain reveals new way to tune electron flow in altermagnet material
Altermagnetism is a new, third type of magnetism of great interest for spin-transport applications like computer memory. If properly harnessed, it could combine...
A 236-million-year-old fossil challenges the story of mammalian live birth
Some cynodonts may have been giving birth to live young much sooner in evolutionary history than previously assumed. A new Frontiers in Mammal Science study has...
African grasslands expanded 5 million year earlier than previously thought, molecular fossils suggest
The iconic grassland savannas of Africa are geographically extensive and important for both local fauna and the global climate. But where did they come from, an...
AI‑designed viruses are a test of whether biosecurity can keep pace
Scientists have crossed an important line in biological engineering. In a recent study, researchers used artificial intelligence to design complete sets of gene...
Drug-carrying nanoparticles shrink venous malformations by 70% in mice
Venous malformations are abnormally shaped veins that develop when the cells lining blood vessels grow too fast when they aren't supposed to. Children can be bo...
Models of glacial collapse in Antarctica improve predictions of sea-level rise
With approximately one-third of the world's population living within a day's walk of a coastline, sea-level rise poses a serious global threat. Every centimeter...
Unsupervised free time increases the likelihood that adolescents will engage in violent behavior, 21-country study finds
A study involving more than 58,000 adolescents from 21 countries found that "unstructured free time"—defined as periods without adult supervision or activities...
What it's like to discover an ancient Egyptian tomb, and the race against time to preserve it
Looking inside a newly discovered ancient tomb for the first time is both exciting and terrifying. I was fortunate to experience this recently as director of an...
Ultrafast flash Joule heating significantly reduces MXene manufacturing time
MXenes are two-dimensional materials made of very thin layers of metals, measured on the atomic scale. They conduct electricity well and have surfaces that can...
Graphene nanowrinkles could reshape electricity in future ultrathin devices
Rice University researchers have shown that tiny wrinkles in graphene can change the material's electrical properties, providing evidence for flexoelectricity,...
Fast-moving wildfires may prevent western forests from recovering
The severe, drought-fueled fires now burning across much of the American West and Canada may be scorching forests so thoroughly that they cannot recover to the...
Pain isn't the point: European viper venoms may have evolved to subdue prey
For many people, the fear of venomous snakes is linked to one thing: pain. Yet new research led by scientists at Bangor University suggests that, for Europe's v...
