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 / Deep-sea larvae travel toward sunlight before returning to hydrothermal vents 2,000 meters down
Hydrothermal vents on the ocean floor host a broad range of rare and unusual ecosystems. They can be spread far apart, yet there is often overlap among the creatures that inhabit them. Researchers, including those from the ...
Phys.org / New study reveals what drives the evolution of remarkable eyes in deep‑sea hyperiid amphipods
Hyperiid amphipods are a small but anatomically diverse group of shrimp-like crustaceans with remarkable adaptations for life in the ocean's twilight zone. A team of researchers from MBARI, the Smithsonian National Museum ...
Phys.org / Tiny water droplets convert stubborn plastic waste into valuable acids, study finds
A new way of converting stubborn plastic waste into high-value chemicals using only water and oxygen has been developed by an international team of scientists.
Phys.org / Unhoused people and wildlife are increasingly coming into contact. Here's what can be done to protect them
As homelessness increases around the world, more unhoused people are turning to parks and other urban green spaces to seek shelter. However, these places are also home to animals that live in and around urban areas.
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 / Bacteria form 'herds' to survive predators, offering fresh insight into Earth's carbon cycle
Researchers at Queen Mary University of London have discovered that tiny photosynthetic bacteria band together into protective "herds" when attacked by predators—a survival strategy that could also influence how carbon is ...
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 / 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 / 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 / Adolescent social media restrictions may reduce some harms while shifting others, warn experts
Amrit Kaur Purba and colleagues argue that social media restrictions operate within a wider system of adolescents, families, schools, governments and commercial actors—and therefore should be treated as complex systems interventions ...
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 ...
