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 / 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 / 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 / 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 / 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 / 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 ...
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 / When disaster strikes, people often flee to places that feel familiar
When the Marshall Fire tore through suburban Colorado in late 2021, residents had only hours to decide where to go. Some fled to nearby towns. Others stayed farther away for weeks or months. Now, a recent study published ...
Phys.org / New species of monkey with unusual orange lips discovered in the Democratic Republic of Congo
Scientists have described a new species of colobus monkey in the forests of the Democratic Republic of Congo (DRC), report John Hart at Lukuru Wildlife Research Foundation and colleagues in PLOS One. The first hint that a ...
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 / New study pinpoints Europe's most critical wetlands for climate action
Wetlands have shaped human life in Europe since ancient times. These ecosystems provided essential resources and safe havens for plants and animals, and in many regions they also held spiritual and ritual significance. For ...
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 ...
