The US Air Force apologized Thursday for its ill-advised attempt to incorporate the viral "Yanny" or "Laurel" meme into a tweet about repelling a Taliban attack in Afghanistan.In what was clearly a major social media fail, the initial tweet -- which was posted by the Air Force's official account earlier in the day -- attempted to put a playful spin on the popular meme currently sweeping the internet by comparing it to the distinctive sound of the 30mm cannons aboard an A-10 Warthog aircraft."The Taliban Forces in Farah city #Afghanistan would much rather have heard #Yanny or #Laurel than the deafening #BRRRT they got courtesy of our #A10," the tweet said.The tweet has since been deleted and replaced with an apology that said the initial post was "made in poor taste.""We apologize for the earlier tweet regarding the A-10. It was made in poor taste and we are addressing it internally. It has since been removed," the second post said.Politicians, corporate brands and even the Department of Defense's official Twitter account have weighed in on the debate centered around a viral audio clip that says either "Yanny" or "Laurel" depending on the listeners interpretation.But the Air Force's post incorporating the pop-culture reference sparked criticism from those who said it was inappropriate to mention the meme in a tweet about the thwarted Taliban attack .When asked about the controversy on Thursday, Pentagon Spokeswoman Dana White said she wasn't aware of the tweet."What is important to understand is that this is the Afghans' fight. We are working by, with and through these partners. And they are dying to secure their own future and I think that shouldn't be forgotten in any of this," she added.The US military helped Afghan troops repel a major Taliban attack on the Afghan provincial capital Farah on Tuesday and Wednesday that punctured the security perimeter surrounding the city, US and NATO officials told CNN.The Pentagon said Thursday some US advisers assisted in the fight and coalition airstrikes also took place. US A-10 attack jets also flew overhead but did not conduct any strikes.It was unclear how close the Taliban came to capturing the city, which would have represented a major blow to the Afghan government.The insurgents claimed they briefly seized the city center, while the NATO-led coalition said it saw no direct evidence that they ever made it into the city.Afghan A-29 attack planes and Mi-17 helicopters carried out multiple airstrikes in defense of the city.US military advisers eventually arrived in the city to assist Afghan military commanders at their headquarters, helping to call in drone strikes that killed some 28 Taliban fighters, Lt. Col. Martin O'Donnell told CNN.He said US troops also arrived to advise Afghan commando units involved in the counterattack but did not participate in offensive operations. 2877

The storm-weary Carolinas are preparing for another round of strong winds and drenching rains -- this time from Hurricane Michael.Michael is speeding toward the Florida Panhandle as a Category 4 storm, and is expected to make landfall Wednesday afternoon.From there, it'll move into the Southeast and some areas in North and South Carolina, where it's expected to bring strong wind gusts and drop 3 to 5 inches of rain when it passes central parts of the states Thursday and Friday, CNN meteorologist Michael Guy said.While it doesn't sound like much compared to last month's record Florence rainfall of 30 inches or more in some areas, any amount of rainfall on already saturated grounds could lead to flooding.Northeast South Carolina, from Columbia toward Myrtle Beach, and southeast North Carolina, were among the areas hardest hit by Florence, and will get a drenching from the latest hurricane, Guy said. While the rain will move quickly compared to Florence, it'll still bring flooding possibilities. 1015

The Wake Forest Institute for Regenerative Medicine says it has a new use for its bioprinting system. In the past they've 3D printed normal-size organs and tissues in hopes of someday implanting them in patients.For the coronavirus, the lab is creating organs using human cells that can be as small as a pinhead. They're focusing on the organs most likely to be infected by the disease. like the lungs.“And so we've been playing with a number of agents to, on both prongs what can make it more infective, what can make it less infective to try to sort this out for the future,” Anthony Atala, director for the institute said.Atala says he hopes the system will help in testing drugs before they hit the market.Drug companies do extensive testing and clinical trials in people before releasing a new medication.Atala says sometimes those companies find no serious side effects, but then years later, discover that it's toxic to patients taking it. Atala says testing a drug using the bioprinting system can tell if a drug is toxic in weeks instead of after years on the market.“Even though we've used the tool extensively for toxicity testing, it's also a tool that can be used for screening,” Atala said. “So we can test agents that are currently being considered for testing against COVID and test the efficacy of the treatment on miniature human organs made up of normal cells”To be clear, Atala said drug tests on 3D printer organs are not meant to replace clinical trials in humans, be are an added step to better predict what will happen in those trials. 1567

The Smithsonian National Zoo in Washington is welcoming its newest member — a baby Lowland gorilla.On Sunday, 15-year-old Calaya gave birth to a son, Moke — "junior" or "little one" in Lingala, a language spoken in Central Africa.“The birth of this western lowland gorilla is very special and significant, not only to our Zoo family but also to this critically endangered species as a whole,” said Meredith Bastian, the National Zoo's curator of primates, according to the Smithsonian. “The primate team’s goal was to set Calaya up for success as best we could, given that she is a first-time mother. Doing so required great patience and dedication on the part of my team, and I am very proud of them and Calaya.”According to the zoo, Cayala has been adjusting well to motherhood and has learned how to care for Moke by watching other gorillas and through the help of staff. Zookeepers helped trained Cayala, in part, by showing her pictures of mother gorillas and presenting her with toys to cuddle and kiss.“This infant’s arrival triggers many emotions—joy, excitement, relief—and pride that all of our perseverance in preparing Calaya for motherhood has paid off,” said animal keeper Melba Brown. “We will provide support to her if need be, but I have every confidence that Calaya will be a great mom to Moke. I am excited to see how he will fit into the group dynamic. There are a lot of different personalities in this family troop, but they all work well together.”Alex Hider is a writer for the E.W.
