They don’t build skyscrapers; they steal them. In forests from Panama to Pennsylvania, climbing vines hitch a ride up the bodies of trees, saving energy on wood and spending it on leaves, speed, and stealth.

Scientists are piecing together their disappearances from scorched eggshells, fossil wind-borne wings, and DNA whispers preserved in desert caves. The mystery isn’t just how these giants lived, but ...

Yet scattered across our planet are organisms that shrug at suffocation, running their metabolisms on alternative chemistry that reads like sci‑fi. Scientists have begun to map this oxygen‑free frontier with new tools, revealing animals that live, ...
