Scientists are building cyborg jellyfish to explore ocean depths

Climate change is warming ocean waters, making the environment more acidic thanks to the absorption of carbon monoxide from the atmosphere. This endangers various marine species, and monitoring those changes is vitally important. But it can be challenging to reach the deepest waters without the aid of very expensive equipment. Moon jellyfish can swim to those depths, however, making them a potential ally in the quest to study the deep ocean. That's why researchers at the University of Colorado

‘Jelly Ice’ Inspired by Tofu Never Melts

Jelly ice is cold but never melts. Jelly ice is jiggly and reusable. Jelly ice is real, and scientists want to bring it to a store near you. In a presentation for ACS Fall 2025, researchers at the University of California (UC), Davis, introduced “jelly ice,” a gelatin-based hydrogel that freezes and thaws without making a watery mess. Everything about jelly ice sounds like something straight from a child’s imagination: edible, reusable, compostable, and squishy. But jelly ice is definitely rea

Nuclear Power Plant Shut Down by Furious Jellyfish

Since its inception, nuclear energy has faced a host of opposition, from oil conglomerates to well-intentioned anti-nuclear-weapons activists to environmental groups. As it turns out, even ocean critters are getting in on the movement. Over the weekend, a swarm of angry jellyfish forced the Gravelines Nuclear Power Station in France — one of Europe's largest — to take four of its six reactors offline. As reported by the New York Times, the "massive and unpredictable presence of jellyfish" was f

Jellyfish Overpower Nuclear Power Plant in Show of Force From Mother Nature

Jellyfish may be spineless, but they showed the backbone of a dedicated environmentalist over the weekend. A swarm of the gelatinous sea dwellers overwhelmed a nuclear power plant in northern France, forcing its shutdown on Sunday. The incident started when a “massive and unpredictable” swarm of jellyfish started to overwhelm the filter drums, which remove debris from cooling water systems, at the Gravelines nuclear power plant that sits on the coast of the North Sea. The sheer volume of jellyf

Tourist Spots ‘Extinct’ Jellyfish Not Seen in 50 Years

Jellyfish enthusiasts rejoice: Depastrum cyathiforme—a wrinkled, barrel-shaped jelly with tiny tentacles for hair—may not actually be extinct, despite being MIA for nearly 50 years. We can thank tourist Neil Roberts, who accidentally came across the jelly while on holiday in South Uist in Scotland. This particular stalked jellyfish was much-beloved during the Victorian and Edwardian eras, appearing in exquisite detail in illustrations by famous naturalists. Historical records suggested the jell

The best Plex alternative in 2025 is Jellyfin, and you really should try it

Robert Triggs / Android Authority Self-hosting is an increasingly popular alternative for those looking to escape the convoluted (and expensive) content-streaming landscape and return to a more traditional personal ownership approach to their media collection.
