Phys.org / T. rex was likely responsible for some tooth marks on fossil bones from Cretaceous era
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 ...
Phys.org / Risks of solar storms may be underestimated, warn researchers
The effects of extreme space weather may be larger than previously thought, research in the journal Nature reveals. The paper, titled "Regression to the mean can explain saturation of geomagnetic storms," is led by Dr. Nithin ...
Phys.org / Large precolonial villages in the Brazilian Cerrado practiced maize-based polyculture, evidence reveals
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 ...
Phys.org / When eyeing a predator, horses keep a poker face as their hearts race
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.
Phys.org / Bone 'fingerprints' unlock hidden stories of underwater caves
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 ...
Phys.org / Climate impact research needs more real-world data, study suggests
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 ...
Phys.org / Birds respond differently to environmental change—and their traits explain why
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.
Phys.org / NASA's Perseverance rover reads record of ancient Mars impacts
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" ...
Phys.org / Antarctic change drives slowdown of global ocean circulation
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 ...
Phys.org / Sweeping analysis shows prestige, topic and location matter most to get research published
Scientists from prestigious universities and large research groups are significantly more likely to have their research published in general-interest, top-tier scientific journals. Meanwhile, authors based in China and those ...
Phys.org / Quantum currents turn a nano 'soccer ball' into a powerful molecular electromagnet
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 ...
Phys.org / Sensitive measurements uncover dual superconducting states in atom-thin NbSe₂ and TaS₂
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 ...
