Phys.org / Universal patterns emerge across 22 languages, mapping how vocabularies evolve
Human languages are known to have grown and changed considerably over the course of history, often reflecting technological, cultural, and societal shifts. Studying the evolution of languages can thus offer valuable insight ...
Medical Xpress / How the brain replays past emotional experiences during sleep
For decades, neuroscientists have been trying to uncover the neural processes that allow humans and various other animals to recall emotional experiences of past events. Past studies have identified a network of brain regions ...
Phys.org / How emoji use at work can determine how competent your colleagues think you are
You've typed it, deleted it and typed it again. You need to let your colleague know there's a problem with a project at work. Should you use a grinning face—😄—in that Slack message to soften the blow, or an angry face—😠—to ...
Medical Xpress / Weight-loss drugs could tackle Alzheimer's—study
A new study has found comprehensive evidence that "weight-loss" GLP-1 receptor agonists such as semaglutide are effective in tackling the biological drivers of Alzheimer's disease. The study, published in the journal Molecular ...
Phys.org / Extreme stability in ultrafast nanomagnetism aids the development of faster data storage
For the first time, researchers have mapped how the boundaries of magnetic nanostructures behave on extremely short timescales. The work of physicist Johan Mentink of Radboud University shows that these boundaries are much ...
Phys.org / Why did Clovis toolmakers choose difficult quartz crystal? New study offers clues
Quartz crystals are difficult to knap due to size, hardness, and crystalline structure, making them a "low-quality" raw material. However, the Clovis people of North America sometimes made points and other tools from this ...
Phys.org / Can warning videos blunt misinformation? What a 12-country test found
The internet and social media platforms have given rise to a rising wave of misinformation, with many users now posting fake news, AI-generated photos or videos and other types of misleading content online. Over the past ...
Phys.org / The threat of light pollution puts the world's darkest skies in the Atacama Desert at risk
It takes a moment for the eyes to adjust. A faint spark appears in the darkness; then another, brighter one. Soon, stars, planets and entire constellations emerge. Before long, a whole galaxy stretches across the sky, visible ...
Phys.org / Deep under Antarctic ice, a long-predicted cosmic whisper finally breaks through in 13 strange bursts
A detector buried deep in Antarctic ice has captured the first experimental evidence of a predicted but never-before-seen phenomenon: radio pulses generated when high-energy cosmic rays slam into the ice sheet and trigger ...
Medical Xpress / Teen vaping quit attempts nearly doubled after 2019 ads and lung injury coverage
Researchers from the University of California San Diego Herbert Wertheim School of Public Health and Human Longevity Science have found that both anti-vaping advertising and widespread news coverage of a lung-injury outbreak ...
Phys.org / This new tool makes AI's role in student writing visible
Generative artificial intelligence (AI) has transformed college writing. As paper drafts are increasingly co-written with AI, professors are left wondering not whether students are using AI, but how. A 2025 AI in Education ...
Tech Xplore / Water-based zinc batteries tackle a barrier that has long blocked cheap, stable renewable energy storage
Renewable energy technologies, such as solar cells and wind turbines, are becoming increasingly widespread in many countries worldwide. Reliably storing the electricity produced by these devices, so that it can be used later ...
