Phys.org / Study finds teens spend nearly a third of the school day on smartphones: Frequent checking linked to poorer attention
A new study from researchers at University of North Carolina at Chapel Hill finds that middle and high school students spend nearly one-third of the school day on their smartphones, checking them dozens of times, often for ...
Phys.org / Ancient hydrothermal carbon fuels microbes and crabs off Taiwan, study reveals
How is carbon metabolized and processed in different ecosystems? In a study published in the journal Communications Earth & Environment, researchers led by Joely Maak, the study's first author and researcher in the Cluster ...
Phys.org / Narrow-ridged finless porpoises are more social than assumed, study finds
A well-established fact of infancy in mammals is that the mother is the primary adult with whom an infant will interact. This holds true across species, from the tiniest shrew to the most massive blue whale. However, infants ...
Phys.org / AI disclosure labels may do more harm than good, study warns
The growing use of AI-generated scientific and science-related content, especially on social media, raises important concerns: these texts may contain false or highly persuasive information that is difficult for users to ...
Phys.org / Superconductivity controlled by a built-in light-confining cavity
For the first time, physicists have demonstrated that a material's superconductivity can be altered by coupling it to an in-built, light-confining cavity. In experiments published in Nature, a team led by Itai Keren at Columbia ...
Phys.org / Quantum entanglement offers route to higher-resolution optical astronomy
Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical sources at the single-photon level. Published in Nature, a team led by Pieter-Jan Stas at Harvard ...
Phys.org / Inland China experienced typhoon-related population decline 3,000 years ago, according to 'oracle bones,' AI and physics
Evidence suggests that China's "cradle of civilization" experienced marked climate disasters and social upheavals during the mid-late Holocene (around 3,000 years ago). However, the direct causes and impacts of these ancient ...
Phys.org / Engineered magnetic films follow graphene's equations for massless electron waves
The electronic and magnetic properties of two-dimensional materials both have strong potential for technological applications. Researchers have long assumed that they are distinct phenomena, but Illinois Grainger engineers ...
Phys.org / How a protein pair ensures that faulty mRNA is destroyed
Nonsense-mediated mRNA decay (NMD) is one of the most important processes in our cells to ensure that no faulty or incomplete proteins are produced. Scientists have now identified a central mechanism behind this control system.
Phys.org / 'Mesoscale' swimmers could pave way for drug delivery robots inside the body
In physics, the mesoscale lies between the microscopic and the macroscopic. It is not just the domain of tiny living creatures like small larvae, shrimp, and jellyfish, but also where physics equations become extreme. While ...
Phys.org / How long does it take to get last liquid drops from kitchen containers? These physicists know the answer
At some point, most people have found themselves holding a tilted carton of milk or bottle of cooking oil, patiently waiting for the last drops to drip out. Now, physicists at Brown University have done the math to show just ...
Phys.org / Twenty-nine years of warming linked to soil fungi shift in Colorado plots
Long-term ecosystem warming changes not only plants but the fungi in the soil below, according to a new study including researchers from the University of Tennessee, Knoxville. "Hidden mycorrhizal fungi below ground are ...
