A hormone already known for curbing appetite and supporting weight loss may have a surprising second job: protecting the liver from inflammation and scarring. Researchers at McMaster University found that GDF15 activates a previously unknown brain-to ...

Scientists analyzing a 2,200-year-old Roman shipwreck found that its hull was coated with pine tar and, in one area, a mixture of tar and beeswax. Pollen trapped in those ancient coatings acted like a geographic fingerprint, revealing the landscapes ...

Two very different types of quantum particles may be able to form stable droplets that hold themselves together, challenging decades of conventional thinking. The prediction could soon be tested experimentally and may reveal an unexpectedly rich ...

For decades, scientists have puzzled over why certain atomic nuclei unexpectedly produce large numbers of low-energy gamma rays. A new experiment traced the effect to magnetic changes inside the nucleus, where protons and neutrons effectively flip .. ...

A colossal cliff system created as the supercontinent Rodinia broke apart may have exposed the heart of the Grand Canyon nearly a billion years before the Colorado River carved it. The ancient landscape could also help explain why enormous sections . ...

Scientists have identified exceptionally rare soft tissue preserved in a 450-million-year-old crinoid fossil, more than 200 million years older than the first dinosaurs. Its delicate tube feet offer a remarkable new window into how some of Earth's .. ...

Ozempic may work in the brain in almost the opposite way scientists expected, activating hunger-linked neurons that appear essential for sustaining fat loss. The surprising discovery in mice could reveal new targets for developing even more effective ...

Specialized brain scans reveal that schizophrenia is linked to widespread loss of the synapses that connect brain cells, with the left side of the brain hit especially hard. The damage follows a surprisingly organized pattern tied to the brain's ...

The human family tree may be due for a major rewrite. Researchers argue that Australopithecus and Paranthropus should be folded into the genus Homo because new fossils have blurred many of the traits once used to separate them. The proposed shake-up ...

Extreme experiments have revealed how diamond behaves at crushing pressures beyond those inside Neptune and Uranus, resolving a decades-old conflict between theory and observation. The results could help scientists boost fusion energy output while .. ...
