Amazon said that beginning Tuesday, customers at its two Amazon Go stores in Seattle can use a device that will scan their palms before entering the store that will sync to their credit card with their hand signature.The company announced the launch in a blog post."We believe Amazon One has broad applicability beyond our retail stores, so we also plan to offer the service to third parties like retailers, stadiums, and office buildings so that more people can benefit from this ease and convenience in more places," Dilip Kumar, Vice President Physical Retail & Technology at Amazon, said in the blog post.The way the contactless device Amazon One works is that customers will insert their credit card into the device, hover their hand over the scanner, and follow the prompts to associate the card with their palm signature built for them by the machine.The company said customers could use both palms or one to enroll. Once a consumer enrolls, they'll need to place their palm over the Amazon One device at the entrance.The company plans to add more of the devices in the coming months to other Amazon stores.Amazon says you don't need an Amazon account to use the Amazon One device.The company said the device "protected by multiple security controls and palm images are never stored on the Amazon One device," according to the FAQ on its site."The images are encrypted and sent to a highly secure area we custom-built in the cloud where we create your palm signature," Kumar said. 1499

After struggling to ramp up coronavirus testing, the U.S. can now screen several million people daily, thanks to a growing supply of rapid tests. But the boom comes with a new challenge: keeping track of the results.All U.S. testing sites are legally required to report their results, positive and negative, to public health agencies. But state health officials say many rapid tests are going unreported, which means some new COVID-19 infections may not be counted.And the situation could get worse, experts say. The federal government is shipping more than 100 million of the newest rapid tests to states for use in public schools, assisted living centers and other new testing sites.“Schools certainly don’t have the capacity to report these tests,” said Dr. Jeffrey Engel of the Council of State and Territorial Epidemiologists. “If it’s done at all it’s likely going to be paper-based, very slow and incomplete.”Early in the outbreak, nearly all U.S. testing relied on genetic tests that could only be developed at high-tech laboratories. Even under the best circumstances, people had to wait about two to three days to get results. Experts pushed for more “point-of-care” rapid testing that could be done in doctors offices, clinics and other sites to quickly find people who are infected, get them into quarantine and stop the spread.Beginning in the summer, cheaper, 15-minute tests — which detect viral proteins called antigens on a nasal swab — became available. The first versions still needed to be processed using portable readers. The millions of new tests from Abbott Laboratories now going out to states are even easier to use: they’re about the size of a credit card and can be developed with a few drops of chemical solution.Federal health officials say about half of the nation’s daily testing capacity now consists of rapid tests.Large hospitals and laboratories electronically feed their results to state health departments, but there is no standardized way to report the rapid tests that are often done elsewhere. And state officials have often been unable to track where these tests are being shipped and whether results are being reported.In Minnesota, officials created a special team to try and get more testing data from nursing homes, schools and other newer testing sites, only to be deluged by faxes and paper files.“It’s definitely a challenge because now we have to do many more things manually than we were with electronic reporting,” said Kristen Ehresmann, of the Minnesota Department of Health.Even before Abbott’s newest BinaxNOW rapid tests hit the market last month, undercounting was a concern.Competitors Quidel and Becton Dickinson have together shipped well over 35 million of their own quick tests since June. But that massive influx of tests hasn’t showed up in national testing numbers, which have mostly ranged between 750,000 and 950,000 daily tests for months.Besides tallying new cases, COVID-19 testing numbers are used to calculate a key metric on the outbreak: the percentage of tests positive for COVID-19. The World Health Organization recommends countries test enough people to drive their percent of positives below 5%. And the U.S. has mostly been hovering around or below that rate since mid-September, a point that President Donald Trump and his top aides have touted to argue that the nation has turned the corner on the outbreak. The figure is down from a peak of 22% in April.But some disease-tracking specialists are skeptical. Engel said his group’s members think they aren’t getting all the results.“So it may be a false conclusion,” he said.One of the challenges to an accurate count: States have wildly different approaches. Some states lump all types of tests together in one report, some don’t tabulate the quick antigen tests at all and others don’t publicize their system. Because antigen tests are more prone to false negatives and sometimes require retesting, most health experts say they should be recorded and analyzed separately. But currently the vast majority of states do not do that and post the results online.The federal government is allocating the tests to states based on their population, rather than helping them develop a strategy based on the size and severity of their outbreaks.“That’s just lazy” said Dr. Michael Mina of Harvard University. “Most states won’t have the expertise to figure out how to use these most appropriately.”Instead, Mina said the federal government should direct the limited test supplies to key hot spots around the country, driving down infections in the hardest-hit communities. Keeping tighter control would also ensure test results are quickly reported.Johns Hopkins University researcher Gigi Gronvall agrees health officials need to carefully consider where and when to deploy the tests. Eventually, methods for tracking the tests will catch up, she said.“I think having the tools to determine if someone is infectious is a higher priority,” she said.___AP data journalist Nicky Forster contributed to this story___Follow Matthew Perrone on Twitter: @AP_FDAwriter___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

After a slew of women came forward to accuse producer Harvey Weinstein and other notable figures in media of sexual harassment, CNN's Anthony Bourdain expressed regret for his participation in and validation of a culture he sees as similarly sexist: the restaurant industry.In an interview Thursday with Poppy Harlow on CNN's "New Day," Bourdain -- whose girlfriend, Asia Argento, is among Weinstein's accusers -- explained that he had "spent nearly 30 years in the restaurant industry, an industry and a culture that has been pervasively hostile to women." 565

Across the U.S., employees at a large media company are working to put books in the hands of children living in poverty.That company — E.W. Scripps — is inviting the public to help.The Scripps Howard Foundation’s annual “If you give a child a book …” literacy campaign has started and will run through the end of August. The literacy campaign has distributed more than 100,000 new books to children across the country since 2017.Now in its third year, the campaign is a partnership of the Foundation, employees of The E.W. Scripps Company and donors who provide matching gifts to advance childhood literacy by increasing access to books. ?Every dollar raised during the “If you give a child a book … ” campaign is used for the purchase of books for children who need them most. Books are purchased at cost through a partnership with Scholastic Book Fairs, further maximizing the purchasing power of every donated dollar.Following the campaign, Scripps news organizations choose a local nonprofit group that works with children and families to receive the books. In addition, the TV stations air stories about the importance of literacy and how to get involved, further amplifying the impact of the campaign.“There is an intrinsic link between the ability to read and a child’s ability to succeed in life,” said Liz Carter, president and chief executive officer of the Scripps Howard Foundation. “By helping children learn to read, we can assure they can have the tools and information they need to reach their potential.”Books presented to program partners on National Reading Day on January 23, 2019.Visit http://ifyougiveabook.com for more information on how to give to this the campaign. 1703
