As governors around the country consider new or stricter restrictions to control the latest surge in coronavirus cases, a recently published study identifies restaurants, cafes and gyms as some of the places having the highest risk of coronavirus spread outside the home.The study, published this week in the journal Nature, looked at data from millions of Americans, tracked by their phones as they went about daily life during the first wave of the pandemic this spring.They used the data and an epidemiological model to run simulations on viral spread at points of interest outside the home. Their findings in the simulations closely matched actual coronavirus caseloads, according to the Washington Post.“We found large variation in predicted reopening risks: on average across metro areas, full-service restaurants, gyms, hotels, cafes, religious organizations, and limited-service restaurants produced the largest predicted increases in infections when reopened,” the study states.Researchers say these locations pose more risk because the mobility data, data showing how mobile people are at these places, shows Americans tend to spend longer amounts of time and at a higher density of people.Their models add support to pandemic measures around the country that limit capacity at some of these points of interest, including capping indoor gatherings to a certain percentage or number of people.“Reducing maximum occupancy substantially reduced risk without sharply reducing overall mobility: capping at 20% maximum occupancy in the Chicago metro area cut down predicted new infections by more than 80% but only lost 42% of overall visits, and we observed similar trends across other metro areas,” researchers stated.The study also looked at disparities in lower income neighborhoods, where more of the population has to leave their home for essential jobs, grocery delivery may not be available or is financially not possible, and businesses tend to be smaller and potentially more crowded.“Because disadvantaged groups suffer a larger burden of infection, it is critical to not just consider the overall impact of reopening plans but also their disparate impact on disadvantaged groups specifically,” the study states.The researchers hope the information is helpful to policymakers and city leaders as they consider reopening restrictions. 2356

As baseball nears the two-week countdown to the start of its delayed season, the coronavirus pandemic continues to keep more players off the field. The latest big name to be sidelined by a positive test for the virus is Eduardo Rodriguez. He was expected to start on opening day for the Boston Red Sox. The San Francisco Giants suspended workouts at Oracle Park as they awaited the results of weekend tests. The Chicago Cubs’ workout was delayed. Red Sox prospect Bobby Dalbec also tested positive for the virus. The Washington Nationals and Houston Astros resumed workouts after canceling practices on Monday because of testing delays.Last week, MLB and the MLBPA jointly announced on Friday that 31 players tested positive for COVID-19 amid the first round of tests as players resume training ahead of this year’s shortened season.Teams began working out last week at ballparks across the US as the coronavirus-shortened season is slated to get underway in three weeks. As part of MLB’s plan to resume, players and support staff will be frequently tested for the virus. 1079

As a third-grade elementary school teacher, Reed Clapp never imagined he would be finishing the school year sitting inside the living room of his home. But the COVID-19 outbreak had other plans for this teacher and so many others across the country.Undeterred by a nationwide pandemic, Clapp was determined to finish out this school year the same as any other: with a play that he and fellow teacher, Karen Snyder, have produced for the last five years.“This is one of the most challenging things I’ve ever taken on,” he said, sitting inside the living room of his home in Nashville, Tennessee.The name of the show Clapp and his class would perform in years past was called, “Grammarella,” a satirical production of Cinderella, where every student plays a part of speech. The character Interrogative, for example, can only speak in questions.On the last day of every school year, Clapp’s students would perform the play in front of their classmates at Madison Creek Elementary School in Hendersonville, Tennessee. It’s become such a hit over the years that there’s typically not an empty seat in the school’s library on opening afternoon, which is also closing night. There’s only one showing.But how could Clapp, harness that same kind of magic without his kids physically at school?After a few weeks of thinking, he decided the answer to that question was right in front of him: he’d move the play to Zoom, a virtual video platform.“Instead of saying, ‘we won’t have a play this year,’ we decided to say, ‘how can we do something that is original and something these kids are proud of?” he said.As summer vacation loomed, Clapp and his third-graders began to double down on their work. This energetic 33-year-old teacher with a thick southern drawl knew the script for “Grammarella” would have to be thrown out. So, he started from scratch and came up with an original screenplay, “Zoomarella.”Students auditioned for lead roles on Zoom, and they even practiced social distancing by picking up costumes that Mr. Clapp and Ms. Snyder had left outside on their front porches.Over the course of a few weeks, the play started coming together. Eight and 9-year-old students learned how to be punctual for rehearsal times, that instead of being held in the classroom, they were being held on Zoom. While Clapp’s original intent was to help students learn grammar, he quickly released that “Zoomarella” was teaching his students more important life skills.“Yes, they’re 8 years old, but when we say, ‘we need some light behind you,’ what we’re really saying is, ‘what can you do to put a light behind you?’” he explained.“These kids have become set designers, light designers, camera operators. It’s amazing,” he added.And for students facing isolation at home, rehearsals offered a sense of a vehicle for creativity that might have otherwise been lost when the school closed.“The stuff that has been the hardest is getting facial expressions and acting with your body. You have to use your body and facial expressions and not just when it’s your turn to talk,” explained 9-year-old Autumn Fair.Weeks of practicing finally paid off for Fair and her classmates, as “Zoomarella” was performed without a hitch during the last week of school. And even though the kids might not have been able to hear the applause through their Zoom meeting, Clapp says he couldn’t have been prouder of his kids.“I hope they take away a moment in time that’s been captured in a unique way. Instead of looking back on all this through news stories, they’ll have this play to look back on,” the proud teacher said.Watch “Zoomarella” below: 3619

Andrea Constand, the key witness in Bill Cosby's retrial on indecent assault charges, testified during cross-examination why she agreed to a .38 million civil settlement in which Cosby did not admit to wrongdoing."I can't speak for him, but I was glad it was over," Constand said in court Monday."(I signed it) because it was a very painstaking process for me and my family, it tore my family apart and we just wanted it over," she added. 448

Apple's latest move in China has privacy advocates and human rights groups worried.The U.S. company is moving iCloud accounts registered in mainland China to state-run Chinese servers on Wednesday along with the digital keys needed to unlock them."The changes being made to iCloud are the latest indication that China's repressive legal environment is making it difficult for Apple to uphold its commitments to user privacy and security," Amnesty International warned in a statement Tuesday.The criticism highlights the tradeoffs major international companies are making in order to do business in China, which is a huge market and vital manufacturing base for Apple.In the past, if Chinese authorities wanted to access Apple's user data, they had to go through an international legal process and comply with U.S. laws on user rights, according to Ronald Deibert, director of the University of Toronto's Citizen Lab, which studies the intersection of digital policy and human rights."They will no longer have to do so if iCloud and cryptographic keys are located in China's jurisdiction," he told CNNMoney.The company taking over Apple's Chinese iCloud operations is Guizhou-Cloud Big Data (GCBD), which is owned by the government of Guizhou province. GCBD did not respond to requests for comment.The change only affects iCloud accounts that are registered in mainland China.Apple made the move to comply with China's latest regulations on cloud services. A controversial cybersecurity law, which went into effect last June, requires companies to keep all data in the country. Beijing has said the measures are necessary to help prevent crime and terrorism, and protect Chinese citizens' privacy.The problem with Chinese cybersecurity laws, Deibert said, is that they also require companies operating in China "to turn over user data to state authorities on demand -- Apple now included."Other big U.S. tech companies have had to take similar steps -- Amazon and Microsoft also struck partnerships with Chinese companies to operate their cloud services in the country.Apple says that it did advocate against iCloud being subject to the new law, but was unsuccessful."Our choice was to offer iCloud under the new laws or discontinue offering the service," an Apple spokesman told CNN. The company decided to keep iCloud in China, because cutting it off "would result in a bad user experience and less data security and privacy for our Chinese customers," he said.Apple users typically use iCloud to store data such as music, photos and contacts.That information can be extremely sensitive. Earlier this month, Reporters Without Borders urged China-based journalists to change the country associated with their iCloud accounts -- which is an option for non-Chinese citizens, according to Apple -- or to close them down entirely.Human rights groups also highlighted the difficult ethical positions Apple could find itself in under the new iCloud arrangement in China.The company has fought for privacy rights in the Unites States. It publicly opposed a judge's order to break into the iPhone of one of the terrorists who carried out the deadly attack in San Bernardino in December 2016, calling the directive "an overreach by the US government."At the time, CEO Tim Cook said complying with the order would have required Apple to build "a backdoor to the iPhone ... something we consider too dangerous to create."Human Rights Watch questioned whether the company would take similar steps to try to protect users' iCloud information in China, where similar privacy rights don't exist."Will Apple challenge laws adopted by the Chinese government that give authorities vast access to that data, especially with respect to encrypted keys that authorities will likely demand?" asked Sophie Richardson, China director for Human Rights Watch.Apple declined to answer that question directly, but it pushed back on concerns that Chinese authorities will have easy access to iCloud users' data."Apple has not created nor were we requested to create any backdoors and Apple will continue to retain control over the encryption keys to iCloud data," the Apple spokesman said."As with other countries, we will respond to legal requests for data that we have in our possession for individual users, never bulk data," he added.Rights groups and privacy advocates are not convinced."China is an authoritarian country with a long track record of problematic human rights abuses, and extensive censorship and surveillance practices," Deibert said.Apple users in China should take "extra and possibly inconvenient precautions not to store sensitive data on Apple's iCloud," he advised.Most of those users have already accepted the new status quo, according to Apple. So far, more than 99.9% of iCloud users in China have chosen to continue using the service, the Apple spokesman said.  4875
