Chernobyl's wildlife: The real story isn't the presence of radiation, it's the absence of humans
"Dogs at Chernobyl are now genetically distinct … thanks to years of exposure to ionizing radiation, study finds."

The fake disease that fooled the internet, and what it says about all of us
Until a few years ago, no one had heard of bixonimania. Then, in 2024, a group of scientists posted findings online announcing the condition, which they claimed affected the eyes after computer use. However, the scientists had made it up—not just the work, but the authors' names, affiliations, locations and funding, which was the University of Fellowship of the Ring and the Galactic Triad.

Microplastics have been found to interact with the gut microbiome. Here's what health effects they might have
Through the air we breathe and the food we eat, we can't help but inhale and ingest tiny bits of plastic every day.

AI-enhanced microscopy produces crisp, real-time video inside live cells
Using artificial intelligence, engineers at the University of California San Diego have developed a new way to watch the inner workings of living cells in real time. The process both captures images that are twice as sharp as conventional microscopes and is fast enough to play as smooth video.

Two blazing quasars caught waltzing into a merger
Astronomers, using the Atacama Large Millimeter/submillimeter Array (ALMA), have confirmed the existence of a close quasar pair housed in a pair of merging galaxies seen when the universe was less than a billion years old, at a redshift of 5.7. The system, designated J2037–4537, is one of only two confirmed quasar pairs at redshift greater than 5 ever found. A paper outlining this work was submitted to the preprint server arXiv on April 7.

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.
