New research confirms that temperature and symptom checks miss many coronavirus infections. A study published Wednesday found that these measures failed to detect infections in new Marine recruits before they started training, even after several weeks of quarantine. Many recruits had no symptoms yet still spread the virus. The work has implications for colleges, prisons, meatpacking plants and and other places that rely on symptom screening. Doctors say more COVID-19 testing is needed, especially in younger people who often don't develop symptoms.“We spent a lot of time putting measures like that in place and they’re probably not worth the time as we had hoped,” said Jodie Guest, a public health researcher at Atlanta’s Emory University who had no role in the research.“Routine testing seems to be better in this age group” because younger adults often have no symptoms, she said.The study was led by researchers from the Icahn School of Medicine at Mount Sinai in New York and the Naval Medical Research Center.It involved 1,848 Marine recruits, about 90% of them men, who were told to isolate themselves for two weeks at home, then in a supervised military quarantine at a closed college campus, The Citadel in Charleston, South Carolina, for two more weeks. That included having a single roommate, wearing masks, keeping at least 6 feet apart and doing most training outdoors. They also had daily fever and symptom checks.The recruits were tested for coronavirus when they arrived for the military quarantine and 7 and 14 days afterward. Sixteen, or about 1%, tested positive on arrival and only one had any symptoms. Another 35 -- an additional 2% -- tested positive during the two-week military quarantine and only four had symptoms.Only recruits who tested negative at the end of both quarantine periods were allowed to go on to Parris Island for basic training.Genetic testing revealed six separate clusters of cases among the recruits.A separate study published Wednesday in the New England journal reports on an outbreak last spring on the aircraft carrier USS Theodore Roosevelt. Among the crew of 4,779, mostly young people, 1,271 became infected; 77% did not show symptoms when diagnosed and 55% never developed any.The case shows that “young, healthy persons can contribute to community spread of infection, often silently,” Dr. Nelson Michael of the Walter Reed Army Institute of Research wrote in a commentary. 2442

NEW YORK (AP) — Apple is the first U.S. company to boast a market value of trillion, just two years after it became the first to reach trillion. Apple shares have gained nearly 60% this year as the company overcame the shutdown of factories in China that produce the iPhone and the closure of its retail sales amid the coronavirus pandemic. The company’s hugely loyal customer base trust its products so much that they continued to buy iPhones and other devices online while stuck at home. Apple recently reported blowout earnings for the April-June quarter.Apple has been at the vanguard of a group of Big Tech companies that are increasingly taking over people’s lives — and the stock market. Just five companies — Apple, Microsoft, Amazon, Facebook and Google’s parent company — account for nearly 23% of the S&P 500’s entire value. 853

NEW YORK — A Manhattan prosecutor trying to get President Donald Trump’s tax returns told a judge that he was justified in demanding them, citing public reports of “extensive and protracted criminal conduct at the Trump Organization.” Trump’s lawyers last month said the grand jury subpoena for the tax returns was issued in bad faith and amounted to harassment of the president. Manhattan District Attorney District Attorney Cyrus R. Vance, Jr., is seeking eight years of the Republican president’s personal and corporate tax records, but has disclosed little about what prompted him to request the records, other than part of the investigation is related to payoffs made to women to keep them quiet about alleged affairs with Trump. 742

NEW YORK CITY — Complaints of fireworks are booming in New York City.There were 1,737 calls about fireworks recorded with 311 in the first half of June, which is more than 80 times the amount in the same time period last year.Brooklyn has had more complaints than any other borough. Borough President Eric Adams doesn't want to see attempts to end the fireworks turn into "fireworks between the police and the community.""It's time for all those who call 311, who don't want heavy-handed policing, it's time to come out of your homes and talk to the young people or the people on your block who are setting fireworks off," he said.Fed up, fatigued or just fascinated, some are turning to social media to ask some form of the same question: What's up with the fireworks?Some suspect they may be shows of support for the protesters following the death of George Floyd. Others wonder whether they're simply a way of blowing off steam after being stuck inside by restrictions meant to limit the spread of the coronavirus.This story was originally published by Cristian Benavides with content from the Associated Press on WPIX in New York City. 1147

NEW YORK (AP) — In a sign of how the pandemic is remaking Hollywood traditions, AMC Theatres and Universal Studios on Tuesday announced an agreement for a shortened theatrical window, with the studio’s films playing for a minimum of just 17 days in cinemas compared to the typical 90 days.Studios have increasingly sought to shorten that window and deliver new movies more quickly into the home.After 17 days, Universal Pictures and Focus Features will have the option to make their films available across premium video on demand platforms, including Netflix, Amazon Prime and AMC Theatres On Demand.“The theatrical experience continues to be the cornerstone of our business. The partnership we’ve forged with AMC is driven by our collective desire to ensure a thriving future for the film distribution ecosystem and to meet consumer demand with flexibility and optionality,” said Donna Langley, Chairman of Universal Filmed Entertainment Group in a press release.This deal applies to U.S. theaters, international distribution between the two companies is still being negotiated.AMC and other theater chains have struggled during the pandemic as businesses closed earlier this year and indoor spaces face state-by-state guidance on social distancing and reopening policies.AMC says this multi-year deal with Universal is a commitment and belief that customers will come back.“We would note that just as restaurants have thrived even though every home has a kitchen, AMC is highly confident that moviegoers will come to our theatres in huge numbers in a post-pandemic world. As people enjoy getting out of their homes, we believe the mystical escape and magical communal experience offered at our theatres will always be a compelling draw," said AMC CEO Adam Aron in a statement.Universal said they are working with AMC and other distribution partners on restarting theatrical releases, including upcoming installments of Fast & Furious, Jurassic World, Despicable Me, and others.Tuesday's agreement repairs a rift between AMC and Universal brought on by the on-demand release of “Trolls World Tour” in April. The new deal covers Universal films in the U.S. over the next three years. 2195
