Astronomers have found stars that repeatedly skim past supermassive black holes, surviving each encounter while producing a new burst of light. In some systems, those flares mysteriously fade with every return. Researchers now think the key may be .. ...

Greenland sharks may live for 400 years without suffering the kind of retinal decline normally associated with aging. Researchers found healthy eye tissue and active proteins specially adapted for seeing blue light in the dim Arctic depths. DNA ...

People who speak several languages may have brains that age more slowly, with four-language speakers showing brains that appeared about 13 years younger than those of monolinguals. Starting earlier and becoming highly fluent were also linked to a ...

Astronomers using JWST have discovered that massive early galaxies contain far more small, faint stars than expected. That hidden population could make some of these galaxies three to four times more massive than previous estimates. The finding makes ...

A simple yeast-based food supplement may help restore the immune system's ability to fight cancer, according to new research in mice. Scientists found that yeast beta-glucan reprogrammed early immune cells in the bone marrow, leading to stronger, ...

Honeybee queens exposed to pesticides can shift some of the contamination into their eggs, revealing a previously unknown survival strategy. The process may protect the queen while putting developing offspring, and potentially the entire colony, at . ...

A tiny, fully intact Indigenous pot buried for roughly 400 years has left archaeologists wondering why such a usable object was deliberately abandoned. Found at a historic Potano-Timucua village in Florida, the mysterious vessel is helping reveal a . ...

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 ...
