El Niño silences Atlantic as climatological peak of hurricane season arrives The climatological peak of Atlantic hurricane season arrives today, September 10, yet the basin remains eerily quiet, largely due to El Niño’s influence. Wind shear remains high across the entire Main Development Region (MDR), while Saharan dust and low instability are severely limiting the numerous tropical waves moving off the coast of Africa. THE TAKEAWAY The Atlantic basin is quiet during hurricane season due to El Niño. In past years, Sept. 10 typically marks the busiest time of the Atlantic hurricane season. However, in the Pacific Basin, hurricane activity continues to be red-hot. The climatological peak of the Atlantic hurricane season arrived Thursday, but experts say the basin is eerily quiet. WHAT IS A SUPER EL NINO? Currently, there are no active storms or areas being monitored for tropical development as El Niño continues to suppress activity.

Hawaii braces for potential direct strike from major Hurricane Lowell 🌀HAWAII ON ALERT: Part of Hawaii is now in the cone of major Category 4 Hurricane Lowell. The National Hurricane Center is warning people in Hawaii that Lowell could still be a major hurricane as it makes its approach early next week. A direct landfall is still possible. Watch FOX Weather for the LATEST update:THE TAKEAWAYMajor Hurricane Lowell could follow a track eerily similar to that of 1992’s Hurricane Iniki. Hurricane Iniki also formed during an El Niño year. Iniki destroyed over 70% of the homes on Kauai and remains Hawaii’s deadliest and costliest hurricane. LIHUE, Hawaii — Major Hurricane Lowell, currently passing south of Hawaii, is forecast to turn northward over the weekend, and could follow a track eerily similar to that of 1992’s Hurricane Iniki, the most devastating storm in the state’s history. LATEST FROM FOX WEATHER HURRICANE SPECIALIST BRYAN NORCROSS Hurricane Lowell forecast cone compared to Hurricane Iniki's 1992 track. (FOX Weather / FOX Weather)Iniki made landfall on Sep.

Des chercheurs indiens transforment la soudure de déchets de circuits imprimés en nanoparticules d'oxyde d'étain de 7,6 nm pour la dégradation des colorantsDes chercheurs à Goa, en Inde, ont converti de l'étain récupéré de soudures de cartes de circuits imprimés usagées en nanoparticules fonctionnelles de dioxyde d'étain, comme le rapporte le Journal of Nanoparticle Research. La lixiviation acide met l'étain en solution avant sa conversion en SnO2 nanostructuré. La diffraction des rayons X a confirmé une phase rutile tétragonale et la spectroscopie photoélectronique X a montré que l'étain se trouve presque entièrement sous forme Sn(IV). La microscopie électronique a révélé des particules quasi sphériques d'un diamètre moyen de 7,6 nm, offrant une grande fraction surfacique pour la photocatalyse. Sous lumière UV, le matériau a éliminé 100 % de la rhodamine B en 165 minutes et réduit la demande chimique en oxygène de 95,2 %, indiquant une quasi-minéralisation ; la cinétique était de pseudo-premier ordre avec une constante de vitesse de 0,0114 par minute. L'efficacité est restée à 91,96 % après cinq cycles.

)The immortal jellyfish is capable of winding back its lifecycle to become young again. Scientists are unlocking its cellular secrets for new strategies to treat diseases of old age. The tiny translucent jellyfish Turritopsis dohrnii is surprisingly hard to kill. The marine biologist Maria Miglietta of Texas A&M University at Galveston has cut them, boiled them, starved them, overloaded their tanks with salt or plopped them in fresh water – but the nifty creatures seem to cheat death every time. Under duress, they stop in their tracks and fall to the bottom of their tank. Then something astonishing happens: the animals transform into balls of cells that bear no resemblance to the tentacled umbrella shape of adult jellyfish, known as the medusa. Within one to three days, a structure called a polyp – an early jellyfish life stage – buds off from this ball of cells and then grows into a colony, which will eventually sprout new medusae. "From one jellyfish that doesn't die, then you get this colony that can form hundreds more," Miglietta says.
