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 into how human societies and cultures have transformed over time.

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 more stable than previously thought. This insight will aid the development of future ultra-fast and compact data storage.

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 to the naked eye.

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 trend report found that 90% of college students use AI in their coursework, with nearly half using it during the drafting process. As AI becomes embedded in everyday writing, traditional tools like Grammarly or Turnitin for evaluating student learning fall short. If AI is to be expected in most student writing, then merely detecting its presence isn't enough.

Ammonia as a clean fuel: 'Do not create a new nitrogen problem,' says researcher‎

Ammonia has been feeding the world for decades as a fertilizer and is now rapidly emerging as a carbon-free fuel for shipping and industry. But if we focus only on CO₂ emissions, we risk creating new nitrogen problems, warns nitrogen expert Jan Willem Erisman in an article published in the journal One Earth.

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 particle cascades inside it. Through results published in Physical Review Letters, astronomers of the Askaryan Radio Array (ARA) Collaboration have validated a key technique, which they hope will eventually allow them to detect some of the rarest and most energetic particles in the universe.

Reading shortcuts for children may be popular, but the research doesn't back them up‎

This year marks the UK's National Year of Reading, which aims to rebuild good reading habits and enjoyment as child and adolescent reading declines year on year.

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 few years, this rise in misinformation has become a heated topic of debate, with some studies suggesting that it could influence voters during political elections.

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 material despite its drawbacks. To determine whether the quartz crystal points of the Clovis were functionally comparable to those made from higher-quality toolstones, Dr. Briggs Buchanan and his colleagues conducted scaling and geometric morphometric analyses on Clovis crystal points. The study is published in Lithic Technology.

Paris has successfully cut noise pollution, but urban birds still can't sing at their natural pitch‎

When Rachel Carson wrote the environmental classic "Silent Spring" in 1962, she warned that unchecked human impacts might create a silent future.
