Scientists are using a variety of methods to study why Kilauea has repeatedly spewed lava fountains since late 2024. They may have ruled out one theory.

A study of 70,000 earthquakes finds tiny tremors often precede larger fracking-linked quakes, offering a warning to halt fluid injection.

Scientists used fiber-optic cables to turn “thunderquakes” into underground maps that could help reveal hidden hazards beneath cities.

Growth rings on a fossil bone suggest at least one mammal ancestor gave birth to live young rather than laying eggs 236 million years ago.

The inferno that sent toxic smoke billowing toward the United States won't be the last. Officials are now battling both the wildfires and misinformation.

Marine cloud brightening could cool part of the Pacific and weaken extreme El Niños, simulations suggest. But the approach could have risks.

The organic molecules could come from life or from ordinary chemistry — only samples returned to Earth can settle it.

Past super El Niños have brought bad flooding, deadly fires and disease outbreaks. Climate experts already expect “shockingly high” temps this winter.

A cold blob of water in the North Atlantic points to a weakening of the Atlantic Meridional Overturning Circulation, researchers report.

As Congo’s Bundibugyo Ebola outbreak grows, public health responders are turning to old-school tactics to fight it as scientists search for new tools.

An ocean current called the Atlantic Meridional Overturning Circulation will weaken by 50 percent by 2100. The question is what to do about it.

An AI trained to use thermal images to detect whale body heat could help warn ships at risk of colliding with the marine mammals.

Soil DNA from Chile to the Antarctic Peninsula ties warmer climates to more plant fungal pathogens, with abundance projected to double by 2100.

A new study links the sun's 11-year cycle to accelerated orbital loss, with debris falling faster once sunspot numbers near their cycle peak.

Conservationists now list the penguins and seals as “Endangered.” Climate change in Antarctica has led to plunging populations.

A cave preserved two animals’ rib cages, cartilage and even traces of protein, revealing a flexible breathing apparatus like that of today’s land dwellers.

The tiny seismic signals of rainwater moving through the ground show how heavy tilling damage soil.

Ryan Gosling is on a mission to save the sun — and Earth — from star-killing microbes. Science News dissects the science behind the sci-fi movie.

The Day After Tomorrow, Snowpiercer, Snowball Earth: Such end-of-days visions of a frozen Earth are fantastical … but can contain a snowflake of truth.

A new analysis of a large fossil shinbone suggests T. rex ancestors came from North America instead of Asia. Not everyone agrees.
