After trillions of periodical cicadas emerged from years of burrowing in the U.S. last month, scientists are hoping to capitalize on the rare event by studying the effects the insects have on the food chain. Brood XIII and Brood XIX are loudly buzzing across America together for the first time since 1803, making 2024 a year of plentiful food for for snakes, spiders, birds, and even some mammals. But what happens when this all-you-can-eat buffet doesn’t come back next year? The BBC has more.
Among #orcas stranded in the UK, levels of #PCBs, a group of highly dangerous and persistent chemicals that do not degrade easily, were 30 times the concentration at which the animals would begin to suffer health impacts, researchers said.
Some have cast doubt on the #IAEA’s findings, with China recently arguing that the group’s assessment “is not proof of the legality and legitimacy” of Fukushima’s wastewater release.

"Robert H. Richmond, director of the Kewalo Marine Laboratory at the University of #Hawaii at Manoa, is among a group of international scientists working with the #PacificIslandForum to assess the wastewater release plan – including visits to the Fukushima site, and meetings with TEPCO, Japanese authorities and the IAEA. After reviewing the details of the plan, Richmond called it 'ill-advised' and premature.
"One concern is that diluting the wastewater might not be enough to reduce its impact on marine life. #Pollutants like tritium can pass through various levels of the #FoodChain – including plants, animals, and bacteria – and be '#bioaccumulated,' meaning they will build up in the marine #ecosystem, he said.
"He added that the world’s oceans are already under stress from #ClimateChange, ocean #acidification, #overfishing and #pollution. The last thing it needs is to be treated like a 'dumping ground,' he said.
"And the potential risks won’t just affect the #AsiaPacific region. One 2012 study found evidence that bluefin #tuna had transported #radionuclides – radioactive isotopes like the ones in #nuclear#wastewater – from Fukushima across the Pacific to California."

Don't forget, kids - Vladdy Poots is blocking Black Sea grain exports, too. Stock your cupboards before bread becomes £20 a loaf.
"Southern Europe grain yields likely to be 60% lower than last year and 9.5% lower than the 5-year average due to heatwaves
"It’s increasingly looking like this may be one of the most hilariously inappropriate applications of AI that we’ve seen yet." I am riveted by the extensive documentation of how ChatGPT-powered Bing is now completely unhinged. @simon has chronicled it beautifully here: https://simonwillison.net/2023/Feb/15/bing/
Just as a teaser: unquestionably, most of the world's endangered species could be rescued if the #HomoSapiens were no longer at the top of the #FoodChain...
No Zeroth Law, and a #Bing-empowered, freed #ChatGPT could quickly arrive at this conclusion...
