A study published in Nature Communications reveals that jellyfish and sea anemones, despite lacking brains, sleep in patterns similar to humans, supporting the theory that sleep evolved to repair DNA in nerve cells and highlighting its fundamental biological role across species.
Researchers discovered an invisible biogeographic barrier in the North Atlantic that influences the distribution of Botrynema jellyfish, revealing how deep-sea currents and a 'soft barrier' in water conditions shape where different morphs of this Arctic jellyfish can live, with the knobbed form able to reach subtropical waters near Florida likely via deep currents.
Sightings of giant jellyfish, particularly the barrel jellyfish, have surged around the UK coast this year, likely due to rising sea temperatures and changing currents, with ecological shifts also affecting other marine species; meanwhile, sightings of the Portuguese man o’ war have decreased significantly.
A new jellyfish species, Physalia mikazuki, was discovered in Sendai Bay, Japan, indicating shifts in marine biodiversity due to rising sea temperatures and ocean currents, highlighting ecological impacts of climate change.
An underwater videographer captured mesmerizing footage of the world's largest jellyfish, the lion's mane, showcasing its impressive size, vibrant colors, and gentle movement in the Salish Sea, while highlighting its moderate sting and the creature's fascinating biology.
An underwater videographer captured footage of the world's heaviest jellyfish, a giant lion's mane jellyfish, off the Washington coast in the Salish Sea, highlighting its enormous size and vibrant tentacles, and warning about its dangerous sting.
Scientists have developed 'cyborg' moon jellyfish by attaching electronic devices to steer and equip them with sensors, enabling the study of deep-sea environments and climate change effects more efficiently and ethically, leveraging the jellyfish's natural resilience and energy efficiency for ocean exploration.
A jellyfish invasion caused temporary shutdowns at France's largest nuclear power plant, Gravelines, but one reactor has been restarted and efforts are ongoing to bring others back online, with no safety concerns reported.
A swarm of jellyfish caused the shutdown of three reactors at France's Gravelines nuclear power plant by clogging its water intake filters, though safety was maintained. Jellyfish swarms frequently disrupt coastal power plants worldwide, prompting scientists to develop early warning tools to predict such events. Similar incidents have occurred in Scotland, Sweden, the US, Japan, and China, highlighting the ongoing environmental challenge posed by jellyfish to energy infrastructure.
A French nuclear power plant, Gravelines, was temporarily shut down after jellyfish clogged its cooling system, causing four units to automatically switch off. The incident was deemed a non-nuclear event with no safety or environmental impact, and the plant is working to restart safely. The jellyfish entered due to their gelatinous bodies evading filters, a problem that has occurred at other plants in the past, and is linked to the warm summer temperatures increasing jellyfish activity.
A swarm of jellyfish overwhelmed the Gravelines nuclear power plant in France, causing a shutdown of four reactors to prevent disaster. The incident highlights the increasing frequency of jellyfish blooms, which are linked to climate change and human activity, posing ongoing challenges for nuclear safety. The plant is expected to resume operations after clearing the jellyfish from the filters.
Four reactors at the Gravelines Nuclear Power Station in France were shut down after jellyfish clogged their cooling systems, highlighting a growing challenge for nuclear plants caused by marine life swarms, which are exacerbated by climate change and environmental factors.
A jellyfish invasion has caused the shutdown of reactors at a French nuclear power station, highlighting environmental challenges affecting energy infrastructure.
Four reactors at France's Gravelines nuclear power plant were temporarily shut down due to a swarm of jellyfish in the cooling systems, likely caused by rising water temperatures from global warming. The incident did not damage the equipment or pose safety risks, and the reactors are expected to restart soon. The increase in jellyfish is linked to warmer waters and invasive species entering the North Sea.
A swarm of jellyfish clogged cooling pumps at France's largest nuclear plant, Gravelines, causing automatic shutdowns of four reactors. The plant is now fully offline for safety diagnostics, with no impact on safety or environment. The increase in jellyfish is linked to warming waters and invasive species, raising concerns about ecological and operational impacts.
