Science News: Recent scientific discoveries and expert analysis

Wednesday, Dec. 10, 2025: Your daily feed of the biggest discoveries and breakthroughs making headlines.

Fingerprints on a Roman burial hold new clues to an unusual liquid gypsum funeral ritual.

There are eye-opening claims that orcas and dolphins are working together on salmon hunts and sharing food — but not everyone is convinced.

Researchers using the James Webb Space Telescope spotted huge stars leaking nitrogen in an early galaxy, hinting that such 'monster stars' might have been the source of ancient supermassive black holes.

Clocks on Mars tick faster by about 477 microseconds each Earth day, a new study suggests. This difference is significantly more than that for our moon, posing potential challenges for future crewed missions.

People with anxiety or insomnia tend to have weaker immunity. The decline of a key immune cell may be a culprit.

The novel 3D wiring architecture and chip fabrication method enable quantum processing units containing 10,000 qubits to fit in a smaller space than today's 100-qubit chips.

Astronomical winter begins Sunday, Dec. 21 in the Northern Hemisphere. Here's how the solstice works.

A newfound mosaic draws inspiration from "Phrygians," a play by the Athenian playwright Aeschylus that survives only in bits and pieces.

A strange X-ray signal spotted decades ago may be the result of a star that got attacked by two black holes, one after the other.

The Amazon rainforest currently has a few days or weeks of hot drought conditions per year, but researchers say this could increase to 150 days per year by 2100.

A new sodium-ion battery offers a cheaper and safer alternative to conventional lithium-ion systems, scientists say, paving the way for more sustainable EVs.

Archaeologists have found the earliest evidence yet of fire technology — and it was created by Neanderthals in England more than 400,000 years ago.

A 1956 eruption collapsed much of the Bezymianny volcano in Kamchatka, Russia, but frequent eruptions since — including a large event in November — means it has now almost completely regrown.

The bright binary star system V Sagittae will flare up multiple times before finally going supernova within the next 100 years. When it explodes, it could be visible to the naked eye even in sunlit skies.

The Arab region just had its hottest year on record, a new climate report reveals.

Scientists uncovered how childhood BK virus infections may set off cancer-causing mutations decades later: by activating a host immune system enzyme that attacks DNA.

Aging comes with graying hair, which may be a sign of the body lowering its risk of cancer, a study suggests.

A brilliant point of light is rising in the eastern sky soon after dark this month, drawing comparisons to the "Star of Bethlehem."

Chemists used waste cooking oil to create a sustainable, super-sticky adhesive that's strong enough to hold up hundreds of pounds of weight.
