NatGeo: Do spiders dream?
UC biologist Nathan Morehouse explains why spiders might
Spiders might be a nightmare for arachnophobes, but do they have them?
A new study by the University of Konstanz suggests as much. Researchers found that jumping spiders experience a sleep-like state with rapid eye movements similar to those observed when we dream.
Rapid-eye-movement sleep has been observed in other animals, particularly mammals, but also fish, birds and reptiles.

National Geographic turned to University of Cincinnati biologist Nathan Morehouse to explain why spiders might dream. If spiders dream, it's “likely to be in most ways completely different from our own,” Morehouse told NatGeo.
Morehouse is director of UC's Institute for Research in Sensing, which examines the myriad ways we and animals perceive the world. He was not part of the sleep study but has examined the vision of jumping spiders around the world.
In his lab in UC's College of Arts and Sciences, he and his students have demonstrated how jumping spiders have amazing color vision. He calls them “walking retinas.”
Jumping spiders are known for their solicitous postures, staring up at you like an expectant puppy with two enormous eyes that provide high-resolution vision. But they also have six smaller eyes that provide a 360-degree, monochromatic view of the world that’s very sensitive to motion, Morehouse said.
So why would spiders need REM sleep?
Morehouse said one of the leading theories about REM sleep is that it allows animals to hone essential survival skills.

App turns smartwatch into detector of structural heart disease
November 10, 2025
An app that uses an AI model to read a single-lead ECG from a smartwatch can detect structural heart disease, researchers reported at the 2025 Scientific Sessions of the American Heart Association. Although the technology requires further validation, researchers said it could help improve the identification of patients with heart failure, valvular conditions and left ventricular hypertrophy before they become symptomatic, which could improve the prognosis for people with these conditions.
