Driving an electric current through a molecule can create a magnetic field. Yet in practice, such fields are often too weak to be detected experimentally. Through theoretical modeling, researchers at the Institute of Science ...

NASA's Perseverance Mars rover has uncovered evidence that a 245-foot-thick (75-meter-thick) stack of ancient rock on the rim of Jezero Crater was built by repeated asteroid impacts. Referred to as the "Broom Point member" ...

A collection of fossilized dinosaur bones from Wyoming features tooth marks that provide evidence that some bites were likely made by Tyrannosaurus rex, according to a study published July 15, 2026, in PLOS One by Bethania ...

New Antarctic research shows the deepest layer of the Southern Ocean is shrinking faster than scientists realized, with the rate of change accelerating over the past decade. This is of worldwide significance because as it ...

For decades, researchers have debated the subsistence strategies of precolonial societies in the Brazilian Cerrado (tropical savanna): Were they hunter-gatherers or intensive maize farmers, and in either case, how did they ...

A sweeping new Cal Poly study of North American birds reveals that environmental change does not affect all species equally and that a bird's traits can explain whether populations rise or fall as local conditions change.

A new study reveals that two widely studied ultrathin superconducting materials are more sophisticated than they appear. Although they seem to behave like simple superconductors with a single energy gap, they actually contain ...

Bones preserved in underwater caves offer a rare and powerful window into the past—but until now, researchers have had limited tools to understand how the remains of extinct megafauna and other animals came to rest in their ...

European cities are experimenting with hundreds of climate solutions, from green roofs to electric vehicles, in hopes of adapting to the warmer world around us. But despite a growing body of research on these solutions, we ...

Horses know a predator when they see one—even if it's only on a video screen while they're standing in a stall, with no sounds, smells or previous experience providing context for what they're viewing, a new study suggests.

Pancreatic cancer is considered one of the deadliest cancers because it is often diagnosed late and is difficult to treat. However, a South Korean research team has developed "smart nanoparticles" that remain hidden in normal ...

Researchers at the College of Design and Engineering at the National University of Singapore have identified a key design principle for building reliable electronics from materials only one atomic layer thick, giving engineers ...
