Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting the two factors are linked in some way, researchers say.

Researchers have confirmed the existence of a new island in the northern part of the Caspian Sea, but they haven't managed to land on it yet.

Record amounts of sargassum are floating in the Caribbean Sea and ending up on beaches from Puerto Rico to Guyana — but scientists aren't sure why there's so much of it in the first place.

For reasons still unknown, Earth's energy imbalance is rising much faster than models can account for. Now, scientists are calling for long-term investment in monitoring capability, so that they can make informed predictions about climate change.

Scientists have found a way to monitor volcanic carbon dioxide levels — one of the first signs a volcano might be about to blow — that doesn't involve trekking up a mountain.

A tropical storm is brewing over the Eastern Pacific south of Acapulco. Clouds and thunderstorms that have been gathering for days will organize in the next 48 hours and could develop into a hurricane.

New research has linked sea level rise and an increase in flooding in the U.S. Northeast over the past 20 years to the breakdown of the Atlantic Meridional Overturning Circulation (AMOC).

Researchers have compiled a list of "ingredients" that could help resource exploration companies locate huge reservoirs of clean hydrogen, a critical element in the transition away from fossil fuels.

Fossil sites in Australia hold pollen and spores from the dinosaur age, when the island straddled the Antarctic Circle. Now, scientists have re-created the habitat of "polar dinosaurs," using these plant remains.

Asian needle ants found in the southeastern states of the U.S. have been spreading north and west for years, but experts now consider them to be a medically important pest and urge caution.

A strange atmospheric pattern known as an "omega block" is preventing the usual eastward progression of weather across the U.S. — but what is this weird block, and when will it go away?

Dead stars may have started churning out vast amounts of gold much earlier in the universe than previously thought, a new study hints. Powerful magnetar flares may be the reason.

Recent findings indicate that dire wolves and gray wolves are distantly related, having diverged about 5.7 million years ago and, as far as scientists can tell, never interbred since then.

Conventional helium production comes with enormous carbon emissions, so scientists are looking for alternatives in places like Yellowstone, Tanzania's Rukwa Rift and India's Bakreswar-Tantloi province.
