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 ...

For years, scientists thought Saturn's moon Titan hid a global ocean beneath its frozen surface. A new look at Cassini data now suggests something very different: a thick, slushy interior with pockets of liquid water rather than an open sea. A subtle ...

Long before opioids flooded communities, something else was quietly changing--and it may have helped set the stage for today's crisis. A new study finds that as church attendance dropped among middle-aged, less educated white Americans, deaths from . ...

Researchers have revealed that so-called "junk DNA" contains powerful switches that help control brain cells linked to Alzheimer's disease. By experimentally testing nearly 1,000 DNA switches in human astrocytes, scientists identified around 150 that ...
