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) — U.S. health officials are taking a new tack in the coronavirus fight by emphasizing recent research that finds a mask protects the person who wears it. Previously, the Centers for Disease Control and Prevention advised masks because of medical evidence that it stops people who are infected with coronavirus — whether they know it or not — from spreading it to others. But this week the CDC posted on its Web site a scientific brief discussing recent studies finding that a wearer gets some protection even if an infected person has no mask.The brief added that adopting a universal masking policy, "can help avert future lockdowns, especially if combined with other non-pharmaceutical interventions such as social distancing, hand hygiene, and adequate ventilation.""Experimental and epidemiological data support community masking to reduce the spread of SARS-CoV-2. The prevention benefit of masking is derived from the combination of source control and personal protection for the mask wearer. The relationship between source control and personal protection is likely complementary and possibly synergistic, so that individual benefit increases with increasing community mask use," the brief read. Researchers pointed to the coronavirus outbreak on the USS Theodore Roosevelt as an example of the effectiveness of mask-wearing, saying, "use of face coverings on-board was associated with a 70% reduced risk."The brief said more research is needed to identify combinations of materials used for face coverings to maximize blocking and filtering effectiveness, as well as durability and comfort. 1620

NEW YORK (AP) -- The nation's largest beauty chain has a deal to place shops in more than 100 Target stores by mid-2021.Ulta Beauty and Target said Tuesday that the shops will be located next to Target's existing beauty sections. Financial terms of the deal weren't disclosed.The partnership comes as the coronavirus pandemic has upended shopping habits. Customers are increasingly focused on one-stop shopping experiences as a way to minimize exposure to COVID-19.But the deal could hurt department stores like Macy's, which had already seen their share of their beauty business eroded even before the pandemic. 620

NEW YORK (AP) — The Cooper Hewitt, Smithsonian Design Museum has acquired two emoji that have helped broaden diversity for users of the tiny pictures. It becomes the third museum to add emoji to their digital collections. The New York museum acquired the “person with headscarf” and “inter-skintone couple” emoji for its burgeoning collection of digital assets. The museum plans an exhibition explaining the significance of the two through interviews and images, but the pandemic has put an opening date in limbo, said Andrea Lipps, Cooper Hewitt’s associate curator of contemporary design.“The desire to acquire these particular emoji arose from what we were seeing as the desire for inclusion and representation of various groups and communities and couples on the emoji keyboard,” Lipps told The Associated Press in an interview ahead of the announcement.The emoji are commonly known as “woman in hijab” and “interracial couple.”The hijab emoji, as it’s informally known, was submitted in 2016 to the Unicode Consortium, a nonprofit that oversees emoji standards with voting members from the world’s top digital companies. A then 15-year-old Saudi Arabian girl, Rayouf Alhumedhi, attracted worldwide attention as she campaigned for its inclusion. She was selected as one of Time magazine’s most influential teens of 2017.The interracial couple emoji was submitted to Unicode in 2018 and arrived on devices last year, giving people their first chance to combine multiple skin tones in a single emoji. It builds on the advocacy work of Katrina Parrott, a Black, Houston-based entrepreneur inspired to create diverse skin tones in emoji after her daughter lamented she couldn’t properly represent herself on keyboards. 1726

NEW YORK (AP) — The streaming of “Hamilton” by the Disney+ streaming service was surely the big event on television screens in American living rooms this past weekend. How many people actually saw it remains a mystery. Disney knows, but isn't telling. The Nielsen company is getting that information, too, but deferring to Disney on when it becomes public. The “Hamilton” airing is the most prominent example yet of how consumption of entertainment is changing, but systems for measuring how many people are watching haven't kept up. It's different for television, where it's easy to find how many people watched President Trump at Mount Rushmore, for instance.Hamilton gave Disney+ a huge boost as its most prominent release since debuting. The taping of the hit Broadway show was originally slated for a 2021 theatrical release, but was moved up during the coronavirus pandemic, which has shuttered all Broadway performances since March. 947
