Roughly 40 million people are estimated to wear a fitness tracker of some kind. Now one of those brands, Fitbit, has teamed up with researchers to try and predict COVID-19 symptoms before they start."About seven years ago when these Fitbits and things were coming out as fitness trackers, we said, Well they're probably pretty good physiological markers, not just fitness markers," said Dr. Michael Snyder with Stanford University's School of Medicine.Dr. Snyder says they were first able to use the technology to help them catch early signs of Lyme disease. The current pandemic has prompted them to take their research a step further."They're mostly built around heart rate which we think is better than skin temperature because not everyone gets a fever with COVID," said Dr. Snyder.Stanford's study is taking place in two phases. In the first, researchers evaluated six months of data in a majority of patients who tested positive for COVID-19. Their research showed COVID-19 patients had an elevated resting heart rate up to nine days before showing any symptoms of the virus."I view these as health monitors in the current pandemic. If we start flagging people as early as possible we’re going to be way [ahead in reducing] the number of cases, probably help people in saying no you shouldn’t go to work today. So, it has broad implications for the economy, pandemic spread and personal health period," said Dr. Snyder.Senior Vice President and General Manager of Fitbit Health Solutions, Amy McDonough, agrees."In particular, resting heart rate, heart rate variability, breathing rate all might change as your body is fighting off illness. So the study is really to look at what are the expressed changes that might happen," said McDonough."I think your immune system engages pretty quickly when you get ill and the cells are probably consuming a lot of energy and your heart needs to pound away to create some of them," said Dr. Snyder.Stanford's second phase of the study starts soon. People who have a fitness tracker can sign up and anonymously share their fitness data. Then, they can get alerted when researchers detect an elevated resting heart rate and possible early signs of contracting a virus."To be able to do that earlier detection can help keep people safe and help understand their body and when they might be fighting off illness," said McDonough.Dr. Snyder is confident in the technology, which he says helped him detect his own case of Lyme disease. "In one case which was on me, it was pretty clear I was ill because of the bio marker but I didn’t feel symptoms and my watch even picked that up. So what that tells you is it can detect disease when you’re presymptomatic as well as in asymptomatic cases which is pretty powerful," said Dr. Snyder.People can sign up for Stanford's study by logging into their Fitbit app or heading to innovations.stanford.edu.As for what Dr. Snyder hopes to take away from this study, he said "I hope to plant a wearable device on every person on the planet. Sixty percent of people have a smartphone so it's totally scalable. These are not expensive devices. They could be a lot cheaper than they are and obviously the ones in the future will be much more health-oriented."Eventually they hope to be able to detect the severity of an illness, as well. 3320

SACRAMENTO, Calif. (AP) — California's attorney general said Tuesday that he won't charge two Sacramento police officers who fatally shot an unarmed black man last year, a killing that set off intense protests.Attorney General Xavier Becerra's announcement follows the Sacramento district attorney's finding this weekend that the two officers broke no laws when they shot 22-year-old Stephon Clark.Officers Terrance Mercadal and Jared Robinet say they mistakenly thought Clark was approaching them with a gun after he ran from them into his grandparents' backyard as police investigated vandalism.Becerra said his review found officers believed Clark was armed and their lives were in danger when they opened fire. Investigators found only a cellphone.RELATED: No charges for Sacramento officers who fatally shot Stephon Clark"Based on our review of the facts and evidence in relation to the law, I'm here to announce today that our investigation has concluded that no criminal charges against the officers involved in the shooting can be sustained," Becerra said.The attorney general emphasized the need for changes and called Clark's killing a "devastating loss." He met with Clark's mother, SeQuette Clark, before announcing his decision. Jamilia Land, a family spokesperson, said SeQuette Clark would speak to reporters later Tuesday.Clark was shot seven times on March 18, 2018, and his killing prompted protests in California's capital city and across the U.S. Sacramento County District Attorney Anne Marie Schubert's decision not to charge the officers has sparked new demonstrations, with more than 80 people arrested Monday in a wealthy Sacramento neighborhood.Clark's family and black community leaders urged Becerra to reach a different conclusion."I would like for the attorney general to prosecute the officers," brother Stevante Clark said Sunday. "I want justice and accountability."Both Becerra and Schubert concluded that the officers feared for their lives when they shot Clark, who they thought was holding a gun. They were pursuing him after receiving calls about someone breaking car windows.The attorney general and district attorney said the evidence showed Clark was advancing toward the officers when they shot him.The decision has increased support from top state officials to change California's legal standard for when police can use deadly force.Lawmakers have revived a measure introduced after Clark's slaying that would make California the first state to allow police to use deadly force only when it's necessary to prevent imminent and serious injury or death and if there's no reasonable alternative, such as warnings or other methods.Strong opposition from law enforcement agencies stalled it last year. 2747

SACRAMENTO, Calif. (AP) — Google says Android phones will be used to sense earthquakes around the world and may one day be able to provide global warnings, with the first mass alert system unveiled Tuesday in California. The Android operating system maker says it's using California's network of seismometers to trigger phone alerts. “This announcement means that California’s world-class earthquake early warning system will be a standard function on every Android phone — giving millions precious seconds to drop, cover and hold on when the big one hits,” Gov. Gavin Newsom said in a statement.Android users who have enabled location services and are near a quake of magnitude 4.5 or greater will receive a full-screen earthquake warning, according to ABC News. Authorities say that could give people nearby precious seconds to seek safety. No app is needed. Google also announced that Android phones around the world will begin acting as mini-seismometers to sense tremors. Beginning next year, that could lead to early warning alerts for users near quakes around the world. 1085

RICHMOND, Va. — Crews have arrived to remove a statue of Confederate General J.E.B. Stuart from Richmond's Monument Avenue — an area of the city that contains several Confederate statues that Mayor Levar Stoney has promised to remove.The J.E.B. Stuart monument is one of about a dozen statues Stoney has ordered be removed from city property.Statues of Confederate General Stonewall Jackson and Confederate Naval Commander Matthew Fontaine Maury were removed from Monument Avenue last week and taken to an undisclosed location. A statue of Confederate President Jefferson Davis was toppled by protesters last month.A statue to Confederate General Robert E. Lee is located on state-owned property and could be removed once legal challenges to its removal make their way through court.The Stuart statue, erected in 1907, is the first monument Stoney promised would be removed following the holiday weekend.The mayor said it would cost .8 million to remove the statues. He said the money would come from the Department of Public Works and be reimbursed by a private fund.While city attorney Haskell Brown told Richmond City Council that Stoney did not have the power to remove statues, Stoney said he believed he is on sound legal ground to remove the statues using his emergency powers as the Emergency Management Director."That's in our Emergency Operations Plan. That is also the part of the governor's declaration of emergency that I'm the emergency manager," Stoney said. "And also, the City Council spoke to this in June 8, when they passed a resolution ordinance that gave me such powers."Stoney said over the course of the last several weeks, thousands have gathered in the city, and there have been more than 139 calls of service along the Monument Avenue corridor.The mayor said failing to remove the statues presented a severe, immediate and growing threat to public safety.Stoney said the removed statues would be placed in temporary storage while Richmond enters a 60-day administrative process during which the city will solicit public input while determining the fate of the statues.This story was originally published by Gabrielle Harmon and Scott Wise on WTVR in Richmond, Virginia. 2206
