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 / 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 / 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 / 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 / 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 / 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 / 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 / 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 / Marsupial newborns get early arms as embryos bypass usual limb-building sequence
Scientists have discovered that marsupial forelimbs (arms) develop much earlier before birth than previously thought, providing new insights into evolutionary innovation and biology.
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 / 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 / Does teleworking reduce carbon emissions? It depends on how you do it
Teleworking—including working from home, coworking or working from other third places—can reduce carbon emissions by eliminating commutes. But if you're not careful, this benefit will be offset by the carbon cost of work-related ...
