Phys.org / Deep inside crocodile skulls, 100 million years of brain evolution barely registers
Although modern crocodiles, alligators, caimans and gharials are restricted to the tropics, their fossil record tells a very different story. Ancient crocodylians once inhabited much of the globe and exhibited a remarkable ...
Phys.org / Cochlea network model reveals how inner ear may sort sound from noise
Over 70 million people in the U.S. are impacted by hearing loss, and age-related hearing loss is the second most common health problem in older adults, according to the Advanced Research Projects Agency for Health. However, ...
Phys.org / Rare inner ear cells point to regenerative hearing treatments
A study by a team of researchers from the Gray Faculty of Medical and Health Sciences at Tel Aviv University offers new hope to millions of people with irreversible hearing loss. The researchers identified a unique biological ...
Phys.org / Light-activated compound kills antibiotic-resistant bacteria by turning its own defense enzyme against it
Antibiotic resistance is becoming an accelerating crisis because of the overuse and misuse of antibiotics over many years. The problem is exacerbated when antibiotics wipe out susceptible bacteria but leave resistant bacteria ...
Phys.org / Measuring process over product: AI approach assesses learning processes
Artificial intelligence (AI) is profoundly reshaping education worldwide. While AI tools increasingly support students in brainstorming, drafting and problem-solving, assessment practices often remain narrowly focused on ...
Medical Xpress / AI companionship may reshape how teens learn conflict, boundaries and empathy
As teenagers increasingly turn to artificial intelligence chatbots for advice about friendships, family conflicts and romantic ties, researchers are raising concerns that the technology could disrupt how young people learn ...
Phys.org / Europe's deadly heat wave scorches east, Slovakia hits record
Europe's most severe heat wave on record set new temperature records in eastern parts of the continent on Monday and forced Ukraine to order power cuts to cope.
Phys.org / Giraffes combine quantities similarly to addition
In addition to humans, some species of primates and birds have demonstrated under experimental conditions their ability to manipulate quantities in tasks that require combining or separating them, in a manner similar to addition ...
Phys.org / New superconductors identified, unlocking process that could yield thousands more
An international team of quantum researchers has shown how machine learning can be used to filter a practically infinite number of possible material combinations to identify candidates for superconductivity. Thanks to the ...
Phys.org / Disorder creates direction-dependent optics in compound semiconductors
An international research team has demonstrated that the intrinsic disorder of the compound semiconductor CuInSnS₄ can be exploited to influence its optical properties. While the atomic vibrations also sense the local disorder, ...
Phys.org / Faster tests reveal six fluoropolymer microplastics, including four rarely tracked types
Scientists around the world have been searching food, water and other environmental media for microplastics and for per- and polyfluoroalkyl substances (PFAS). But microfluoroplastics (MFPs), the intersection between these ...
Science X / Built-in 'antenna' may help cells sense a healing spark to guide repair after injury
When skin is wounded, it doesn't just send out chemical distress signals; it also generates a subtle electrical field. This "electric beacon" forms as the usual voltage across the tissue collapses, creating a guiding current ...
