Phys.org / AI extracts interpretable constitutive laws directly from solid-mechanics data
Researchers at the Eastern Institute of Technology (EIT), Ningbo, have developed a graph-based approach that directly extracts concise, accurate constitutive equations from solid-material experimental data. The study, published ...
Phys.org / Low-cost phone lessons keep children learning during emergency school closures across five countries
The COVID-19 pandemic lockdowns forced people to find ways to get things done remotely. Companies developed systems that made working from home run smoothly. Educators also had to shift to mobile phones and group video calls ...
Phys.org / Giant volcanic blanket reveals hidden 'Pompeii' of Andean landscapes
A vast sheet of volcanic rock in the Andes has preserved clues to a buried landscape that existed 22 million years ago, according to a new study led by UCL (University College London) researchers.
Phys.org / Fertilizers and extreme heat are damaging coral reefs in the Gulf of Mexico, isotope analyses reveal
Who isn't familiar with the colorful coral reefs from movies like "Finding Nemo" or "The Little Mermaid"? Unfortunately, the reality is often quite different, as these vital ecosystems are under pressure worldwide. Climate ...
Phys.org / Healthy checkout policy shows promise for reducing soda sales and increasing healthy snack purchases
In March 2021, Berkeley, Calif., became the first city in the world to ban the display of sugary beverages and snacks in store checkout lanes, where candy, chocolate and soda are commonly placed to encourage impulse buying ...
Phys.org / Smart pen detects pressure and movement to identify children's writing difficulties sooner
A study by Politecnico di Milano and the University of Insubria (Varese and Como) has been published in PLOS Digital Health. The study involved more than 700 children from primary and lower secondary school. The participants ...
Phys.org / Electrical pulses convert PFAS waste into valuable silver fluoride
Fluorinated waste, like that found in firefighting aqueous film-forming foam, can act as a significant environmental pollutant. Recently, James Tour's lab at Rice University developed a method to capture fluoride from these ...
Phys.org / First Antarctic-wide map of grounded icebergs reveals 'picket fence effect' holding sea ice in place
For the first time, important features of the Antarctic coastal zone have been mapped at high resolution around the continent by training an artificial intelligence tool to accurately recognize grounded icebergs in satellite ...
Phys.org / AI-generated images may support conservation, but real-world data remain essential
New research finds there is no substitute for real-world observations, but that—under the right circumstances—AI-generated images can be used to improve the performance of computer models used for species identification and ...
Phys.org / Single nanostructure enables independent control of two light resonance modes
Metallic nanostructures are exceptionally effective at concentrating light into tiny volumes, while dielectric nanostructures excel at storing light with minimal energy loss. Combining these complementary properties has traditionally ...
Phys.org / Faster wood formation matters more than longer growing seasons in a warming climate
In non-tropical forests, cold winters hinder tree growth. There, climate warming prolongs the period during which trees absorb carbon through photosynthesis and store it in wood, known as the growing season. This could potentially ...
Phys.org / Seasonal forecasts could give northern India months of warning before severe winter air pollution
Northern India experiences some of the world's worst winter air pollution, with dangerous episodes often prompting emergency control efforts. In major cities like Delhi, the Air Quality Index has reached levels above 999—over ...
