Hubble has uncovered a rare ultra-massive white dwarf created in a violent star merger. Once thought to be ordinary, the star's ultraviolet signature revealed its explosive history and hinted that such cosmic collisions may be surprisingly common.

Astronomers studying an oddball brown dwarf called "The Accident" have finally spotted silane, a long-predicted silicon molecule missing from Jupiter and Saturn's skies. Its ancient, oxygen-poor atmosphere allowed the molecule to form, offering new . ...

NASA's Perseverance rover has discovered mudstones in Mars' Jezero Crater that contain organic carbon and unusual textures hinting at possible biosignatures. These findings suggest that ancient Martian environments may have supported chemical ...

Scientists in Canada have uncovered a surprising culprit behind high blood sugar and liver problems: a hidden fuel made by gut bacteria. This little-known molecule, called D-lactate, slips into the bloodstream and pushes the liver to make too much .. ...

Glioblastoma's stealthy spread has met a new challenge: MRI-powered fluid flow mapping that reveals where the cancer is likely to invade next. The innovation is now being advanced by a spinoff company to guide personalized cancer treatments.

A groundbreaking discovery on the Indonesian island of Sulawesi reveals that early hominins crossed treacherous seas over a million years ago, leaving behind stone tools that reshape our understanding of ancient migration. These findings, older than ...

Physicists have unveiled a new superconducting detector sensitive enough to hunt dark matter particles smaller than electrons. By capturing faint photon signals, the device pushes the search into uncharted territory.

Scientists at Stellenbosch University have uncovered a rare class of plant compounds, flavoalkaloids, in Cannabis leaves for the first time. Using advanced two-dimensional chromatography and mass spectrometry, they identified 79 phenolic compounds .. ...

Metformin, long trusted for diabetes, turns out to work in the brain too. By shutting down Rap1 in the hypothalamus, the drug lowers blood sugar more effectively than previously understood, opening doors for new therapies.

Researchers in Germany and Australia have created a simple but powerful tool to detect nanoplastics--tiny, invisible particles that can slip through skin and even the blood-brain barrier. Using an "optical sieve" test strip viewed under a regular ...
