Phys.org / Atomic bands in two transition metal dichalcogenides hint at long-theorized quantum state

Insulators are materials in which electrons cannot move freely. Past theoretical studies predicted the existence of an unusual insulating state dubbed obstructed atomic insulator (OAI), in which electrons are localized inside ...

Phys.org / Beluga calls deciphered to bolster conservation efforts

Alaska's Cook Inlet was home to nearly 1,300 beluga whales in the late 1970s, but today the population hovers around 300. Despite almost two decades of recovery work, the whales aren't bouncing back. The Cook Inlet belugas ...

Science X / Cities are rewriting growth rules as wealth rises, pollution drops and a long-assumed link starts to break

Cities are a double-edged sword. They provide plenty of job opportunities, and most of the world's money is made in them, but on the other hand, they create most of the planet's pollution. For decades, the prevailing view ...

Tech Xplore / Governments may shape what AI chatbots say by shaping the web they learn from

Ask an AI model the same political question in two different languages, and you may get two very different responses. A new study in Nature suggests one reason why: governments can indirectly influence large language models ...

Phys.org / Identity traits sharply narrow who becomes friends or marries, model reveals

Our personal identity is composed of many dimensions, such as age, gender, ethnic background, or socioeconomic status. A research team led by Fariba Karimi from the Institute of Human-Centered Computing at Graz University ...

Medical Xpress / Too little sleep—and too much—associated with faster aging

An analysis of biological clocks throughout the human body suggests that too few hours of sleep—and too many—may speed aging in the brain, heart, lung, and immune system and is associated with a wide range of diseases.
