Phys.org / Time crystals could become accurate and efficient timekeepers
Time crystals could one day provide a reliable foundation for ultra-precise quantum clocks, new mathematical analysis has revealed. Published in Physical Review Letters, the research was led by Ludmila Viotti at the Abdus ...
Phys.org / Antarctic ice melt can change global ocean circulation, sediment cores suggest
A new study shows that during the last two deglaciations, i.e., the transition from an ice age to the warm interglacial periods, meltwater from the Antarctic ice sheet intensified stratification in the Southern Ocean. The ...
Phys.org / If alien signals have already reached Earth, why haven't we seen them?
For decades, scientists have searched the skies for signs of extraterrestrial technology. A study from EPFL asks a sharp question: if alien signals have already reached Earth without us noticing, what should we realistically ...
Phys.org / Strong correlations and superconductivity observed in a supermoiré lattice
Two or more graphene layers that are stacked with a small twist angle in relation to each other form a so-called moiré lattice. This characteristic pattern influences the movement of electrons inside materials, which can ...
Phys.org / Arctic peatlands are expanding as temperatures continue to rise, new research confirms
The Arctic is warming faster than the rest of the planet, with average temperatures increasing by about 4°C in the last four decades. A new study, led by the University of Exeter, shows peatlands have expanded since 1950, ...
Phys.org / How Indigenous ideas about nonlinear time can help us navigate ecological crises
It is common to think of time as moving in only one direction—from point A, through point B, to point C.
Medical Xpress / A common biomarker of schizophrenia and bipolar disorder revealed
For decades, schizophrenia and bipolar disorder (BD) were treated as distinct and unrelated psychiatric disorders. Schizophrenia is a psychiatric disorder characterized by altered thinking and emotional patterns, hallucinations, ...
Phys.org / Hunting dark matter 'stars' that mimic black holes
Hypothetical dark matter stars known as "boson stars" could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. In 2019, a strange event was observed ...
Phys.org / Ancient cone-shaped vessels may have served as beeswax lamps during ritual processions, study finds
Chalcolithic cornets are conical ceramic vessels produced exclusively during the Chalcolithic period, recovered in abundance at some archaeological sites but absent at others. Their function has long been debated. However, ...
Medical Xpress / Can you spot an AI face? A new test shows why some people do better
Can you tell the difference between an artificial-intelligence-generated face and a real one? In an era of digital misinformation, where fabricated images can spread widely across news and social media, this skill is proving ...
Phys.org / Study of 65,000 college students links 16 hours a week on social media to higher loneliness
More than half of college students are lonely—and those who use social media the most are particularly likely to feel isolated, a study of tens of thousands of 18 to 24-year-olds in the US shows. Just 16 hours a week—two ...
Tech Xplore / Why AI may overcomplicate answers: Humans and LLMs show 'addition bias,' often choosing extra steps over subtraction
When making decisions and judgments, humans can fall into common "traps," known as cognitive biases. A cognitive bias is essentially the tendency to process information in a specific way or follow a systematic pattern. One ...
