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 / Asteroid breakup may explain inner solar system bombardment 800 million years ago
A Southwest Research Institute-led study has proposed a connection between a specific collision in the main asteroid belt and an inner-solar-system-wide bombardment episode that may have had measurable biological and geological ...
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 / 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 / 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 ...
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 / Elephants turn footsteps into messages through ground and skull vibrations
Elephants can communicate with other elephants across distances of up to five kilometers (3 miles) by producing sounds that travel through the air. However, they have a second way of sending signals: seismic waves traveling ...
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 / Prey accessibility, not abundance, may shape predator behavior in penguins
Large seabird colonies have a surrounding boundary known as Ashmole's halo, where food sources are depleted, forcing the birds to travel farther to gather the food they need. The reason seems obvious—the more birds, the more ...
Phys.org / Faintest planet ever imaged from Earth found after more than 10 years of hide-and-seek
A team of astronomers has discovered a third planet orbiting the star Beta Pictoris. The new planet, Beta Pictoris d, is 100 times fainter than Beta Pictoris b—the first planet discovered in the same system—and is among the ...
Phys.org / Stealth anticancer nanoparticles made from mussel proteins that 'lie in wait and attack only cancer cells'
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 ...
Phys.org / New method scales up twist-engineered oxide materials for future electronics
Researchers have shown it is possible to expand the field of twistronics—literally. They have demonstrated a technique that allows them to fabricate oxide twistronic materials at much larger scales while also controlling ...
