  1. 💁🏻‍♀️ TIL: 🪸💨 University of #Chicago researchers watched dime-sized Clytia hemisphaerica #jellyfish close wounds in minutes.

    Lamellipodia crawl across tissue, then an actomyosin cable cinches like a purse string. The simplified model could eventually inform mammalian regenerative #medicine.

  2. #Jellyfish Shut Four French #NuclearReactors as #HeatWave Builds

    "#Electricite de France SA [#EDF] was forced to shut four #AtomicReactors after a swarm of jellyfish clogged up filter drums at its #Gravelines power plant.

    "The 'massive and unforeseen' [um, not if you read my posts -- very much FORESEEN] presence of jellyfish in the filter drums of pumping stations closed four out of six reactors at Gravelines on the north coast of France, EDF said in a statement on Monday. Pumping stations for coastal #NuclearPlants usually draw in sea water for cooling, sometimes exposing them to marine life.

    "A #MarineHeatWave is intensifying off the west coast of France, with unusually warm waters in the English Channel near Gravelines, data from #Copernicus Marine Service show. Jellyfish populations can 'bloom' at such times, and France has closed several beaches in recent weeks due to invasions of the eight-legged molluscs, according reports compiled by the beach information app Meduseo."

    Invasion of #jellyfish, heat, water too hot: #GlobalWarming threatens the functioning of #NuclearPowerPlants

    Several reactors are regularly forced to stop to protect river #biodiversity. While cuts in periods of high heat still have a very limited impact on supply, electrification of uses and #ClimateChange could make a difference.

    "When nature paralyses the French nuclear park. Four units of the Gravelines nuclear power plant (northern) are at a standstill on Monday 11 August due to the 'mass and unforeseeable presence of jellyfish; at the water pumping stations used for the cooling of the reactors, EDF announced.

    "These automatic stops of units 2, 3, 4 and 6 'have had no consequences on the safety of the installations, the safety of personnel or on the environment', #EDF assures on its site. The plant is thus temporarily completely shut down, as its other two production units 1 and 5 are currently under maintenance.

    "On Sunday, 29 June, no steam volutes escaped from the chimneys of the Gulf nuclear power plant (Tarn-et-Garonne). Due to the intense #HeatWave in #France, the reactor in operation at the site was shut down. In the middle of the summer of 2024, the nuclear power plant had already been forced to reduce its production."
