Google and Apple teamed up to create a software that allows a COVID-19 tracking app to work. It’s part of a recent software update on smartphones.Now, Virginia is the first state to make an app using the technology. It's called COVIDWISE. It's similar to contact tracing but isn't exactly the same.COVIDWISE uses Bluetooth technology to measure distance between different people and how much time they've spent together. Both people need to have the app installed.Users will receive an alert if someone around them tests positive for coronavirus and it won't reveal who it was.While not everybody needs to have the app, the more people who do, the better.“For every one to two app users, you're potentially averting one infection, so I think that's a good take-home message,” said Jeff Stover, Executive Program Advisor at the Virginia Department of Health. “So, obviously the more of them there are, the more potential infections that we avert.”The app is really only meant to notify people if they've been exposed to the coronavirus. It's not meant to eliminate traditional contact tracing.“Traditional contact tracing is still important. It is still required. It's really how we get in touch with people to determine if they have questions, if they have prevention activities that they need to figure out,” said Stover.Another thing about the app is that it does not use location data. Virginia's health department says there's really no need for it, especially because that type of data doesn't really show the distance between people.Right now, the app can only be used in Virginia, but the state of North Dakota has said the app will be available for use there soon. 1680

The Venice Film Festival will go from Sept. 2 through Sept. 12. Italy was among the countries hardest hit by the coronavirus pandemic, and the festival will serve as a celebration of its re-opening and a sign that the film world, largely on pause since March, is coming back as well.

Half of the coral populations in the Great Barrier Reef off Australia’s coast have been killed off because of warming ocean waters, a new study says.Between 25-30 percent of all marine species rely on coral reefs at some point in their life cycle. The Great Barrier Reef is the world’s largest coral reef, covering nearly 133,000 square miles.It has more than 411 species of hard corals documented, as well as 1,500 species of fish and other animals.Researchers looking at coral populations over 30 years starting in 1995 found there was decline in both shallow and deeper water, and across different species. They said two in particular, branching and table-shaped corals, were especially hard hit in 2016 and 2017 because of record-breaking temperatures.The study finds climate change to be a key driver in reef disturbances that disrupt recovery.“The potential for recovery of older fecund corals is uncertain given the increasing frequency and intensity of disturbance events. The systematic decline in smaller colonies across regions, habitats and taxa, suggests that a decline in recruitment has further eroded the recovery potential and resilience of coral populations,” the researchers note.They also say the coral that spawn the larvae that makes more coral have declined dramatically over large stretches of the reef.“Corals are tremendously resilient because of their capacity to produce millions of babies but they/we desperately need a break from disturbances,” Andreas Dietzel, a professor at the ARC Center and a co-author of the paper, said in an email to the Washington Post. 1600

Hours after Amazon instructed its employees to remove the short-video sharing app TikTok from their devices -- the company back stepped.The online retail giant says the email was sent in error and there is no change to amazon's policy regarding TikTok.In the email sent to employees Friday morning and obtained by CNN, Amazon said that due to "security risks, the TikTok app is no longer permitted on mobile devices that can access Amazon email."A TikTok spokesperson said Amazon "did not communicate to us before sending their email, and we still do not understand their concerns."Politicians say the app could undermine national security given its ties to China.Cybersecurity experts have been more cautious about that assessment.TikTok is owned by the world's most valuable startup, a Chinese company named Bytedance. 828
