Stanford researchers discovered immune cells in flatworms that explode within minutes, killing nearby bacteria and foreign cells before vanishing completely. Their unusually fast and localized attack could offer clues for developing targeted ...

August brings four major celestial events, including a solar eclipse and the peak of the Perseid meteor shower. Dark New Moon skies could make the Perseids especially impressive, while Venus will blaze in the west after sunset. A deep partial lunar . ...

Fossilized dinosaur bones from Wyoming are offering a rare glimpse into the feeding behavior of Tyrannosaurus rex. Researchers examined more than 3,000 bones dating back 72 to 66 million years and found just 12 with possible tooth traces, including . ...

Scientists have uncovered a surprising way that "jumping genes" may move between species and speed up evolution. While these mobile genetic elements were thought to travel mainly inside viruses or plasmids, researchers found circular intron RNA from ...

A specially engineered chewing gum reduced HPV by up to 93% and nearly eliminated two bacteria linked to head and neck cancer. The treatment preserved beneficial mouth bacteria, raising hopes for a safer and more affordable therapy.

A tiny 518-million-year-old sea creature has revealed the earliest known evidence of the structures that eventually became spiders' fangs. Hidden inside the fossil were pincerlike limbs and preserved soft tissues that help explain how the ancestors . ...

Scientists have successfully generated electricity with a hydrogen turbine that produces its own pressure through detonation waves instead of relying on a mechanical compressor. The breakthrough could unlock dramatically more efficient power systems ...

Animal bones preserved in South Australia's underwater caves reveal distinctive clues shaped by darkness, algae, bacteria, and other environmental conditions. The findings give scientists a powerful new way to reconstruct how ancient megafauna ...

Photons traveling through a cloud of atoms can emerge so early that they appear to have spent a negative amount of time inside. Researchers tested whether this was merely a misleading feature of the light pulse by making extremely weak measurements . ...

DNA traces in the Shroud of Turin reveal a remarkable mixture of human lineages, microbes, plants, animals, and coral accumulated through centuries of handling and travel. The findings do not prove its age or authenticity, but they expose a hidden .. ...
