New data shows that those who use Duolingo — a popular language app — can learn the equivalent of four semesters of university study. The app is free for all, and parents and teachers say it is a good supplement for students of all ages who are learning from home this fall.Averill, 10, is quite the Duolingo master. Her Spanish teacher recommended the app to pair with her in class lessons a few years back. Averill took that one step further.She's currently learning Korean. When she masters that, it will be her third language."My dad is Korean, and so my grandparents speak Korean," Averill said. "I'm trying to learn it because we're planning a trip to Korea to visit some relatives and I'm trying to learn it so I can speak to them a little bet,ter than I can right now."She likes to take what she's learned and practice on her grandparents. So far, she says, she's doing pretty well.Korean and Spanish are two of the 39 featured languages on Duolingo. This spring, when COVID-19 sent America into lockdown, new users flocked to the app. Dr. Cindy Blanco is a learning scientist at Duolingo."Our new users spiked 66%, which in any other time would be enormous but the spike continued the rest of the month," said Dr. Cindy Blanco, a learning scientist at Duolingo. "Our new user growth in March was 113%, which is unprecedented — kind of the word of the year."People were also downloading the app to keep their language skills sharp and because teachers needed help."The most important thing to not fall behind in a language course is to keep getting in front of that language," Blanco said.As a Doctor of Linguistics, Blanco is a Duolingo user herself. She's currently trying to keep up with her Russian. She's already well-versed in Spanish, French, Catalan, Italian and American Sign Language.Blanco says Duolingo offers all sorts of content, including lessons, short stories, podcasts, and seven a virtual language practicing event. Because Duolingo is app-based, it means users can access it from anywhere, anytime."It's more important than ever that we create products that can meet people where they are and where they are is at home with small handheld devices," Blanco said. "So, how can we get language learning literally in your hands?"It's also fun. The program moves away from textbooks and worksheets that many find monotonous, especially when it comes to language."We often associated language-learning with dry high school classes of textbooks and worksheets," Blanco said. "So, to see something that's fun, that you like doing, you're deceiving yourself. 'Well, I can't possibly also be learning, I'm enjoying it too much.'" 2655

NEW YORK (AP) — “Sesame Street” has always pressed for inclusion. Now in the wake of the national reckoning on race, it’s going further — teaching children to stand up against racism. Sesame Workshop — the nonprofit, educational organization behind “Sesame Street” — will air the half-hour anti-racist special “The Power of We” and hopes families will watch together. The special defines racism and shows how it can be hurtful. It urges children who encounter racism or hear someone else be the victim of it to call it out. Gabrielle the Muppet advises: “When you see something that’s wrong, speak up and say, ‘That’s wrong’ and tell an adult."“Sesame Street has the ability to entertain children while explaining complex issues like no other program and equips families and caregivers with the support they need to have empathetic conversations,” said Kay Wilson Stallings, Executive Vice President of Creative and Production at Sesame Workshop. “We believe that this moment calls for a direct discussion about racism to help children grasp the issues and teach them that they are never too young to be ‘upstanders’ for themselves, one another, and their communities.”The special will stream on HBO Max and PBS KIDS starting Thursday, October 15, PBS says. The special will also be aired on PBS stations throughout the United States. 1342

NEW YORK — An influential scientific panel on Tuesday voted to recommend to the CDC that when a COVID-19 vaccine becomes available, both front line health care workers and residents in long-term care facilities should be prioritized first. The Advisory Committee on Immunization Practices voted 14-1 in favor of adopting the following recommendation: When a COVID-19 vaccine is authorized by FDA and recommended by ACIP, vaccination in the initial phase of the COVID-19 vaccination program (Phase 1a) should be offered to both 1) health care personnel and 2) residents of long-term care facilities.Watch the meeting live here."About one (American) dies every minute from COVID-19. During this ACIP meeting, about 120 people will die," Dr. Beth Bell said during initial remarks at the beginning of the virtual meeting Tuesday.The ACIP met Tuesday afternoon in an open-to-the-public, virtual meeting to vote on the proposal that gives priority to health care workers and patients in nursing homes and other long-term care facilities. The two groups together represent around 23 million Americans out of a population of about 330 million; about 21 million in health care professions and less than 3 million adults living in long-term care facilities.Current estimates project around 40 million doses combined available by the end of 2020. And each vaccine product requires two doses.The CDC said Tuesday they expect 5-to-10 million doses available each week after a vaccine is authorized by the FDA. They say these numbers necessitate the need for sub-group prioritizing, since not all health care workers or long-term care facilities can be vaccinated at once. Another consideration the panel discussed is not having an entire unit or group get vaccinated at once; if there are side effects like fatigue or other symptoms that necessitates taking a day or two off, this could leave a unit critically short-staffed. During Tuesday's presentation, Dr. Kathleen Dooling talked about statistics from COVID-19 patients in the US and how it lead to health care workers and long-term facility staff and patients to be at the top of the vaccine list. Long-term care facilities are responsible for six percent of COVID-19 cases and 40 percent of COVID-19 deaths in this country, she said. Later this month, the Food and Drug Administration will consider approval of two vaccines made by Pfizer and Moderna. The panel meeting Tuesday said they hope to learn more about the safety and effectiveness of the vaccines as more information is released by the FDA.Dr. Dooling said one of the questions they hope to ask about the Phase 3 trial data of both Pfizer and Moderna is how effective one dose of the vaccine has shown to be. They will also be taking a deeper look at the age groups of those included in the trial, and the efficacy of the vaccines on older people. Some of the comments during the public comment section referenced the lack of transparency released at this time about the vaccines and the panel trying to make vaccination decisions without it. However, the panel, while voting, expressed faith in the FDA's process of approving the vaccine as safe for all Americans. Once vaccines are given, the CDC and FDA will be asking all health care providers and facilities to use the existing Vaccine Adverse Event Reporting System, VAERS, to monitor any side effects and adverse reactions to the COVID-19 vaccines. The advisory panel will meet again at some point to decide who should be next in line. Among the possibilities: teachers, police, firefighters and workers in other essential fields such as food production and transportation; the elderly; and people with underlying medical conditions.Experts say the vaccine will probably not become widely available in the U.S. until the spring.ACIP is a 15-member panel of outside scientific experts, created in 1964, that makes recommendations to the director of the Centers for Disease Control and Prevention, who almost always approves them. Childhood vaccine schedules are one example of the work of this group. The recommendations are not binding, but for decades they have been widely heeded by doctors, and they have determined the scope and funding of U.S. vaccination programs.It will be up to state authorities whether to follow the guidance. It will also be left to them to make further, more detailed decisions if necessary — for example, whether to put emergency room doctors and nurses ahead of other health care workers if vaccine supplies are low. 4517

NEW YORK (AP) — Johnny Depp has exited the "Fantastic Beasts" franchise following his failed libel case against The Sun tabloid newspaper for a 2018 article that labeled him a "wife-beater." Depp said Friday in a letter posted on Instagram that he would depart the role of dark wizard Gellert Grindelwald after the studio requested his resignation. Depp said his announcement came "in light of recent events." On Monday, a U.K. judge ruled that an April 2018 article in the British tabloid, which accused him of assaulting his then-wife and fellow actor Amber Heard, was not libelous.Warner Bros. confirmed Depp's departure and said the role will be recast. "We thank Johnny for his work on the films to date," the studio said in a statement. The third "Fantastic Beasts" film is currently in production. 812
