Are masks complicating facial recognition software? The short answer is no, but masks do complicate matters.Computer science experts say that face coverings and other accessories may act as a speedbump, but it wouldn’t be very difficult for the software to be modified.However, with a face covering, recognition may be less accurate.“It has fewer data points and that is the concern,” Steve Beaty, computer science professor at Metro State University-Denver, said. “Because you are essentially removing your nose and your mouth from the equation if you will, there will be fewer data points and the concern is that other people can authenticate as you.”Before the use of face masks, facial recognition software had an inaccuracy rate of less than 1 percent. Now, the National Institute of Standards and Technology estimates that the inaccuracy rate has increased from 5 to 20 percent. 892

Americans aren’t exercising like they used to.“I’ve definitely been walking a whole lot less since the coronavirus hit,” Nathan Martin said.With social distancing orders put into place, the pandemic has many people spending more time at home.“I was a little bit less active and more Netflix,” Hannah Hockensmith said.Now, a new study is showing this drop in physical activity is increasing health concerns across the globe.“COVID-19 is a worldwide phenomenon unlike anything else we’ve seen in generations,” said Dr. Geoff Tison, a cardiologist at the University of California, San Francisco.Tison recently finished a new study using smartphone apps to track the step counts from almost half a million people in countries worldwide.The data was collected from mid-January to early June and the findings show the world is walking a lot less.“Within the first month of the pandemic, declaration activity decreased by about 27%,” he said.Tison says this lack of physical activity could damage people’s health, especially in older adults.“With decreased activity, increased sitting on the couch, just not being as active is muscle mass can start to decrease as can bone density,” he said.In America, the study shows the biggest drop in step counts happened in New York City while Dallas had the smallest decrease.“The changes in activity seem to reflect adherence to social distancing at least to a degree,” Tison said.To increase exercise indoors, Tison says is all about thinking outside the box.“You can do similar exercises, work similar muscles with things around the house,” he said. “Use a gallon of milk instead of a dumbbell.”To exercise outdoors, however, Tison believes changes need to happen at the city and state levels.“Policy makers, governments need to be creative understanding that people are humans and want to be active and want do things,” he said. “But to enable them to do that safely.” 1913

As coronavirus cases begin to jump again in the United Kingdom, Prime Minster Boris Johnson announced Wednesday a nationwide ban on gatherings of more than six people. The ban goes into effect on Monday.While coronavirus cases in the UK currently pale in comparison to the spread of the virus in the US, the UK has seen a marked jump in infections. According to New York Times data, the rate of new cases has doubled from three weeks ago. Johnson’s announcement comes as the UK reported 32 coronavirus-related deaths on Tuesday, the most in a single day since July 29.The UK has a population of 66 million, which is nearly one-fifth the population of the United States, which reported 462 coronavirus-related deaths on Tuesday.Previously, the UK had a ban on all gatherings of more than 30 people.“It will be enforced by the police. And anyone breaking the rules risks being dispersed, fined and possibly arrested,” Johnson said.Johnson told reporters on Wednesday that limiting gatherings is an important step in stopping the spread of the virus.“I should stress that if we are to beat the virus, then everyone at all times should limit social contact as much as possible and minimize interactions with other households,” Johnson said. “It's safer to meet outdoors, and you should keep your distance from anyone you don't live with, even if they're close friends or family.”Since the start of the pandemic, the UK has reported more than 41,000 coronavirus-related deaths. In April, the UK was among the hardest hit nations in the world, with its per capita death rate worse than the United States. But the number of coronavirus-related deaths, which peaked at nearly 1,000 per day, quickly dropped in May. As of last week, the UK was averaging fewer than 10 coronavirus-related deaths per day.But the spike in cases has prompted Johnson to impose a stricter mandate on social gatherings.The ban allow some exceptions for workplaces, schools, funerals and weddings.A number of other nations have implemented similar, but less stringent bans on gatherings. Australia allows gatherings of up to 50 people in private residences, and 100 people in non-residences. Justin Boggs is a writer for the E.W. Scripps National Desk.

An Atlanta police officer has been fired following the fatal shooting of a black man and a second officer was placed on administrative duty. The move announced by police early Sunday comes on the heels of the resignation of Atlanta's police chief following the killing of 27-year-old Rayshard Brooks. Police identified the fired officer as Garrett Rolfe. Atlanta Mayor Keisha Lance Bottoms said she doesn’t believe the shooting was justified. "It has become abundantly clear that over the last couple weeks in Atlanta is that while we have a police force full of men and women who work alongside our communities with honor respect and dignity," Bottoms said, "there has been a disconnect with what our expectations are, and should be as it relates to interactions with our officers and the communities in which they are entrusted to protect."The Georgia Bureau of Investigation say Brooks resisted arrest after he failed a field sobriety test and a struggle ensued over a Taser. Police say 36 people were arrested at Saturday night protests. A Wendy's restaurant, which was the site of Brooks' death, was destroyed amid the unrest on Saturday.Police have released body camera and dash camera footage.The Georgia Bureau of Investigations said that officers responded to a call of a man who fell asleep behind the wheel in a drive thru. The police accused Brooks of failing a field sobriety test.Police then claimed Brooks struggled with officers during the arrest. The Georgia Bureau of Investigations said that officers then fired a Taser at Brooks.Eyewitnesses told investigators that Brooks then struggled with officers over the Taser, and that’s when Rolfe officer shot Brooks.Brooks was transported to the hospital, and he died during surgery.Atlanta has been the site of a number of large protests in recent weeks in the wake of the death of George Floyd. Floyd died on Memorial Day in police custody after a Minneapolis police officer held a knee against his neck for nearly nine minutes.The NAACP reacted to Saturday's shooting via Twitter."Stop urging the black community to be patient as our people are being gunned down by those sworn to 'protect and serve.' Sweeping police reform is no longer a consideration," the NAACP said in a statement. 2261

Andrea Constand, the key witness in the retrial of Bill Cosby on indecent assault charges, testified Friday morning that she drank wine and took three blue pills at Cosby's urging in January 2004, then lost consciousness and, sometime later, was "jolted awake" to find the entertainer sexually assaulting her."Were you able to verbalize and tell him to stop?" state prosecutor Kristen Feden asked Constand."No," she replied. "I wanted it to stop. I couldn't say anything. I was trying to get my hands to move, my legs to move and the message just wasn't getting there. I was weak, I was limp and I couldn't fight him off.""I was really humiliated. I was in shock. And I was really confused," Constand added.Constand's testimony came on the ninth day of Cosby's retrial on three charges of aggravated indecent assault. He has pleaded not guilty.Leading up to Constand's recollection of the alleged assault, the former Temple University employee traced her relationship with Cosby, whom she said she met while handling operations of the school's women's basketball team. Cosby was an active Temple alumnus.Constand offered brief details of seven social encounters she had with Cosby before the alleged assault, including one in which she said he put his hand on her thigh and another when she said he tried to "unbutton my button on my pants.""I mentioned that I wasn't here for that, and he respectfully stopped and we never talked about it again," Constand said of the latter incident. "He got the picture."After that encounter -- but before the early 2004 incident -- "I had no question about my ability to fend off a person that was hitting on me or making a sexual advance on me," Constand testified.Constand began her testimony Friday as prosecutors this week opened their case: by acknowledging that Cosby paid Constand .38 million as part of a civil settlement. She said she has no further legal action pending against Cosby, who, in that case, admitted he got prescription sedatives to give to women with whom he wanted to have sex.Feden is expected to continue questioning Constand early Friday afternoon, after a short court recess.  2157
