Science News: Recent scientific discoveries and expert analysis

See the stunning timelapse captured by photographer Aaron Watson showing ghostly airglow ripples pass through the Colorado sky.

Here's when and where to look for the best chance of seeing Noctilucent, 'night shining' clouds in summer 2025.

A type of hydrogen that doesn't interact with light could explain how long neutrons live and reveal the identity of the universe's dark matter, according to a new theory.

The ice on the surface of Jupiter's massive moon Europa is constantly changing, hinting at the presence of a subsurface ocean, new James Webb telescope observations reveal.

By controlling individual atoms, researchers have demonstrated a way to turn previously unwanted atomic motion into an advantage.

A British metal detectorist discovered a gold band with an engraved date-of-death in Norfolk.

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.

An artificial intelligence safety firm has found that OpenAI's o3 and o4-mini models sometimes refuse to shut down, and will sabotage computer scripts in order to keep working on tasks.

The site's architecture may indicate the Judaean princess was buried there.

A large sunspot has just reappeared on the sun's Earth-facing surface, almost two months after it first emerged. The unusually old dark patch remains stable and could be on course to become the longest-lived sunspot on record, experts claim.

First theorized in 1938, heat's wave-like flow through superfluids, known as "second sound", has proven difficult to directly observe. Now, a new technique has finally done it, and could be used to study neutron stars and high-temperature superconductors.

A NASA-funded plan to build a large radio telescope on the moon's far side is nearing final approval and could become a reality by the 2030s, researchers say. The ambitious project will help safeguard astronomy from satellite "megaconstellations" — and help scientists unravel more of the radio spectrum.

The number of satellites orbiting Earth is rising fast, thanks to private companies such as SpaceX. But just how big will these "megaconstellations" become? And what problems might they cause?

Two studies of ancient felines find that cats were likely domesticated in Egypt or other regions in North Africa — and moved into Europe with humans much later than previously believed.

A study of more than 100 genomes from people who lived in ancient China has unmasked a "ghost" in their midst.

A cocktail of FDA-approved cancer drugs, trametinib and rapamycin, boosts the lifespan of lab mice by 30% and might help humans age better, new study finds.

By combining data from the Subaru Telescope and James Webb Space Telescope, researchers have discovered distant quasars that are obscured by dust but which may shed light on Little Red Dots.

A cutting-edge technique for analyzing fossil tooth enamel is revealing remarkable new information about 2 million-year-old human relatives.

Alterations to a single gene in the plague bacterium's genome have shed light on a method the germ has used to survive and spread through the ages.

A major collection of more than 50 bird fossils found in northern Alaska suggest some ancient ancestors of modern birds learned to either adapt to the harsh Arctic winter, or migrate south during the Mesozoic — the age of dinosaurs.
