A newly described hydrozoan jellyfish species off Japan keeps a self-sustained 20-hour cycle that governs sunset spawning, suggesting an alternate, non-traditional circadian mechanism that evolved without standard clock genes.
NASA tested gravity sensing in space by sending thousands of jellyfish polyps to orbit in the 1990s. After about nine days, tens of thousands of jellyfish developed, but once returned to Earth the space-born jellyfish struggled to swim and exhibited vertigo, suggesting that humans born in space might also face difficulties re-adapting to Earth's gravity.
Scientists filming off Argentina’s coast with the Schmidt Ocean Institute’s ROV SuBastian captured rare footage of Stygiomedusa gigantea, a schoolbus-sized phantom jellyfish that can reach about 33 feet in length at depths around 820 feet; the deep-sea sighting, notable for its four ribbon-like arms used to snare prey, came amid footage of potential new species and rich reef systems uncovered during the expedition.
Venice’s lagoon is being invaded by Mnemiopsis leidyi, the warty comb jelly known as the sea walnut, originally from the western Atlantic and now spreading through the Adriatic likely via ballast water and warmer waters linked to climate change. Scientists warn the invasive jellyfish are proliferating, clogging nets and preying on fish eggs, larvae and plankton, which harms the lagoon ecosystem and threatens the region’s multi‑billion‑euro fishing industry as conditions become increasingly favorable for its spread.
Naomi Osaka debuted a jellyfish-inspired on-court outfit — a turquoise, tentacle‑accented look by Nike, Marty Harper, and Robert Wun — at the Australian Open, featuring a pleated miniskirt over wide-leg trousers, a wide-brim hat with veil and parasol; she defeated Antonia Ruzic 6-3, 3-6, 6-4, marking a landmark moment for couture in live tennis.
Naomi Osaka opened the Australian Open with a bold butterfly-themed entrance—featuring a wide-brim hat, veil and a white parasol—before defeating Antonia Ruzic 6-3, 3-6, 6-4. The look nods to her 2021 Melbourne success and jellyfish-inspired dress, while the event’s water motif and a remodeled Rod Laver Arena tunnel provided a backdrop as she eyes a second-round match against Sorana Cirstea and builds confidence.
Naomi Osaka kicked off her Australian Open campaign with a jellyfish-inspired ocean-blue outfit designed with Nike and London stylist Robert Wun, dedicating it to her daughter Shai. She beat Antonia Ruzic 6-3, 3-6, 6-4 at Rod Laver Arena to reach round two, with commentators praising both the statement look and her performance.
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.
