Scientists just found a surprising clue","descripcion":"Scientists have discovered that spiders may sleep in ways surprisingly similar to humans, complete with distinct sleep stages and a dream-like REM state. Researchers at the University of Bonn studied the Australian jumping spider Portia fimbriata, a remarkably clever hunter known for its sophisticated strategies. By recording the spiders over several days and nights, they found clear evidence of regulated sleep, including a REM-like stage marked by eye movements and muscle twitches.","pubDate":"Tue, 27 Oct 2026 00:53:11 EDT","url":"https://www.sciencedaily.com/releases/2026/10/261026225555.htm"},"indexado":"2026-10-27T12:03:48.284Z"}}
