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 . ...

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 .. ...

Weight loss is not simply a test of willpower. The human brain evolved to protect body fat during times of scarcity, and it can treat a previously higher weight as the new normal, triggering stronger hunger, cravings, and lower energy use after ...

Scientists have named a newly discovered beetle genus Luffy, inspired by the stretchy hero of the manga and anime One Piece. The insects have unusually long, slender mandibles, antennae, and mouthparts that resemble Luffy's rubber-like ability to ...

Taiwan's steep, remote mountains have sheltered extraordinary forests containing hundreds of giant Taiwania firs. After years of difficult expeditions, LiDAR mapping, and citizen-science detective work, researchers discovered an 84.1-meter (276-foot) ...

Low arginine levels may allow cancer cells and viruses to slip past the immune system by reducing production of a crucial cellular warning protein. In mice, arginine-rich diets led to fewer colon tumors and milder viral infections, suggesting a ...
