Cheetos are a no-go, and the recent park visitor who dropped a bag full of them created a “huge impact” on the cave’s ecosystem, the park said Friday in a Facebook post. “At the scale of human perspective, a spilled snack bag may seem trivial, but to the life of the cave it can be world changing,” the park said in its post about the garbage found off-trail in the Big Room. https://kra07.gl kra12.cc “The processed corn, softened by the humidity of the cave, formed the perfect environment to host microbial life and fungi. Cave crickets, mites, spiders and flies soon organize into a temporary food web, dispersing the nutrients to the surrounding cave and formations. Molds spread higher up the nearby surfaces, fruit, die and stink. And the cycle continues.” The park said rangers spent 20 minutes carefully removing molds and foreign debris from surfaces inside the cave, noting that while some members of the ecosystem that rose from the snacks were cave-dwellers “many of the microbial life and molds are not.” The post called that particular impact on the cave “completely avoidable,” contrasting it with the hard-to-prevent fine trails of lint left by each visitor. “Great or small we all leave an impact wherever we go. Let us all leave the world a better place than we found it,” the post urged park goers. The park’s website says that eating and drinking anything other than plain water attracts animals into the cavern. Carlsbad Caverns followed up its post about the Cheetos bag with a post about the “leave no trace” principle of disposing of waste properly. “Contrary to popular belief, the cave is NOT a big trash can,” the post said, yet rangers pick up waste left behind every day. “Sometimes this can be a gum wrapper or a tissue, other times it can unfortunately mean human waste, spit, or chewing tobacco.” Visitors are asked to make sure they don’t leave trash in the cavern and to use designated restrooms.
• 16/09/2024 - 08:55 Гость Study shows how the pandemic may have affected teens’ brains a href=https://kra12gl.com kra4.gl /a The pandemic’s effects on teenagers were profound — numerous studies have documented reports of issues with their mental health, social lives and more. Now, a new study suggests those phenomena caused some adolescents’ brains to age much faster than they normally would — 4.2 years faster in girls and 1.4 years faster in boys on average, according to the study published Monday in the journal Proceedings of the National Academy of Sciences. By being the first to contribute details on aging differences by sex, the study adds to the existing body of knowledge provided by two previous studies on the Covid-19 pandemic and accelerated brain aging among adolescents. https://kra7.gl-kra7.cc kraken зеркало “The findings are an important wake-up call about the fragility of the teenage brain,” said senior study author Dr. Patricia K. Kuhl, the Bezos Family Foundation Endowed Chair in Early Childhood Learning and codirector of the Institute for Learning and Brain Sciences at the University of Washington in Seattle, via email. “Teens need our support now more than ever.” Significant socioemotional development occurs during adolescence, along with substantial changes to brain structure and function. The thickness of the cerebral cortex naturally peaks during childhood, steadily decreases throughout adolescence and continues to decrease through one’s lifespan, the authors wrote. The researchers originally intended to track ordinary adolescent brain development over time, starting with MRIs the authors conducted on participants’ brains in 2018. They planned to follow up with them for another scan in 2020. The pandemic delayed the second MRI by three to four years — when the 130 participants based in Washington state were between ages 12 and 20. The authors excluded adolescents who had been diagnosed with a developmental or psychiatric disorder or who were taking psychotropic medications.
• 16/09/2024 - 07:16 Гость Long-lost copy of the US Constitution, found in North Carolina filing cabinet, heads to auction a href=https://kra04.at кракен сайт /a Historical document appraiser and collector Seth Kaller spreads a broad sheet of paper across a desk. It’s in good enough condition that he can handle it, carefully, with clean, bare hands. There are just a few creases and tiny discolorations, even though it’s just a few weeks shy of 237 years old and has spent who knows how long inside a filing cabinet in North Carolina. At the top of the first page are familiar words but in regular type instead of the sweeping Gothic script we’re used to seeing: “WE, the People …” And the people will get a chance to bid for this copy of the US Constitution — the only of its type thought to be in private hands — at a sale by Brunk Auctions on Sept. 28 in Asheville, North Carolina. https://kraken2trfqodidvlh4aa337cpzfrhdlfldhve5nf7njhumwr7instad.ltd kra14.cc The minimum bid for the auction of $1 million has already been made. There is no minimum price that must be reached. This copy was printed after the Constitutional Convention finished drafting the proposed framework of the nation’s government in 1787 and sent it to the Congress of the ineffective first American government under the Articles of Confederation, requesting they send it to the states to be ratified by the people. It’s one of about 100 copies printed by the secretary of that Congress, Charles Thomson. Just eight are known to still exist and the other seven are publicly owned.
