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 / Brain's ability to hear a musical beat remains distinctly human, study suggests
The seemingly trivial ability to hear a regular pulse in music is a remarkable—and perhaps distinctively human—feature of the brain. In a wide-ranging critical review, Gábor Háden of the HUN-REN Research Centre for Natural ...
Phys.org / How one RNA nucleotide switch activates fluorescent dyes
RhoBAST is a tiny RNA molecule that activates fluorescent dyes, enabling researchers to track RNA molecules in living cells with super-resolution. An international collaboration, which includes Ronald Micura and his team ...
Phys.org / New genome study rewrites the early history of grasses, the world's most important plant family
An international team of scientists, including Donald Danforth Plant Science Center member emerita Elizabeth "Toby" Kellogg, Ph.D., has produced a chromosome-level genome assembly that offers a new view of the earliest evolution ...
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 / 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 / Compost microbe yields enzyme that tackles polyurethane foam and nylon
Researchers from Aarhus University and the Danish Technological Institute have taken a new approach in the search for enzymes capable of breaking down some of the most difficult types of plastic to recycle. They collected ...
Phys.org / AI helps find hidden human proteins and reveals what they do
New research shows how artificial intelligence, combined with advanced experimental science, can help find "hidden" and unexplored proteins in the human body and reveal what they actually do, according to a new study published ...
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 / 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 / When will your glacier disappear? New website lets users explore risks worldwide
When will the glacier in your valley disappear? Will the glacier you visited as a child still exist in 2050? And how much difference would limiting global warming make?
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 ...
