Phys.org / Nanoscale hairs may help gecko skin trap moisture and slow evaporation
In a dry shrubland, a gecko sprints toward shelter. Its greatest danger is not a predator, although hawks circle overhead and sand cats wait in ambush. Rather, its most pressing concern is dehydration. Its skin is paper-thin; ...
Phys.org / How people treat you may shape your reputation and stabilize cooperation
When one person helps, or refuses to help, another in public, this may change not only the provider's reputation but also the recipient's. A theoretical study led by Kobe University offers a simple explanation for how cooperation ...
Phys.org / Chatbots are making our writing more similar but losing the identity and personality behind it
Large language models (LLMs) are making writing styles more similar without changing the overall meaning, according to an analysis of more than 880,000 texts across different writing types published in Nature Human Behaviour. ...
Phys.org / AI financial advice can improve decisions or steer investors wrong, experiment finds
To what extent can AI improve our financial decisions or steer us in the wrong direction? Researchers at the University of Bayreuth investigated this question in a new study involving 3,700 participants and fictional investment ...
Phys.org / How the sun's galactic journey and superflare-filled youth shaped Earth's climate
At the center of our solar system, the sun influences every planet that orbits it. In two recent studies, scientists uncovered how ancient events in the sun's history may have helped create Earth's unique climate and driven ...
Phys.org / Cowpea plants create underground defense system for the next generation after insect attacks
Plants might seem helpless when it comes to insect attacks, but they are known to employ various techniques to deter pests. One of these techniques involves sending out signals to recruit parasitoid wasps, and a new study, ...
Phys.org / A 4-star system caught eclipsing itself in a way never seen before
Astronomers have found a four-star system doing something that has never been confirmed before. The system, TIC 433545934, has two close pairs of stars orbiting each other. While each pair eclipses its own two stars, as usual, ...
Phys.org / Mapping thorium's preferred sites could pave the way for nuclear clocks
For decades, physicists have used a technique called Mössbauer spectroscopy to peer inside solid materials, revealing fine details of their surroundings by studying how their atomic nuclei absorb and re-emit gamma rays.
Phys.org / Marker words suggest sharp rise in AI-assisted biomedical writing after ChatGPT
Up until two years ago, using large language models was still considered a special skill that everyone was encouraged to learn. Now, it is ubiquitous, especially in writing research papers that eventually become part of the ...
Phys.org / Why ancient grasslands, once plowed, don't grow back the same
When a 10,000-year-old prairie is plowed up to plant corn or a savanna is consumed by a strip mall, these once-grassy expanses, if left to regrow, can eventually look vaguely like they did before. But a growing body of research ...
Phys.org / Mystery statue unearthed at Sardis archaeological dig
Researchers with the long-running Harvard–Cornell Archaeological Exploration of Sardis have unearthed a larger-than-life statue estimated to be nearly 2,500 years old.
Phys.org / Vacuum-fluctuation-enhanced superconductivity demonstrated for the first time
In a study published in Nature on Aug. 19, a research team has enhanced superconductivity through vacuum fluctuations for the first time. The achievement marks a significant advance in controlling quantum states of matter.
