Eating full-fat cheese and cream may be associated with a lower risk of dementia, according to a large study that tracked people for more than 25 years. Those who consumed higher amounts of these foods developed dementia less often than those who ate ...

Researchers studying a massive landslide in Alaska have detected strange seasonal seismic pulses caused by water freezing and thawing in rock cracks. These faint signals could become an important early clue to changes that might someday trigger a ...

Sediments from a Roman latrine at Vindolanda show soldiers were infected with multiple intestinal parasites, including roundworm, whipworm, and Giardia -- the first time Giardia has been identified in Roman Britain. These parasites spread through ...

Researchers have found that fossilized dinosaur eggshells contain a natural clock that can reveal when dinosaurs lived. The technique delivers surprisingly precise ages and could revolutionize how fossil sites around the world are dated.

Astronomers have uncovered a massive hidden planet and a rare "failed star" by combining ultra-precise space data with some of the sharpest ground-based images ever taken. Using the Subaru Telescope in Hawaii, the OASIS survey tracked subtle stellar ...

Superconductors promise loss-free electricity, but most only work at extreme cold. Hydrogen-rich materials changed that--yet their inner workings remained hidden because they only exist under enormous pressure. Now, researchers have directly measured ...

By studying tiny distortions in the shapes of distant galaxies, scientists mapped dark matter and dark energy across one of the largest sky surveys ever assembled. Their results back the standard picture of the universe and show that even archival .. ...

Old military air samples turned out to be a treasure trove of biological DNA, allowing scientists to track moss spores over 35 years. The results show mosses now release spores up to a month earlier than in the 1990s. Even more surprising, the timing ...

Balanophora is a plant that abandoned photosynthesis long ago and now lives entirely as a parasite on tree roots, hidden in dark forest undergrowth. Scientists surveying rare populations across East Asian islands uncovered how its cellular machinery ...

An instrument aboard NASA's Europa Clipper spacecraft captured rare ultraviolet observations of an interstellar comet while Earth-based telescopes were blinded by the Sun. The spacecraft's unique position provided an unprecedented look at the comet's ...
