As mixed messages continue regarding face coverings, Mississippi became the first state to lift a statewide mask mandate. Cities and towns can now put their own rules in place.The governor said the facts and data still show masks work, and the state is still requiring them at certain events, including the state fair that starts this week.“I suspect Mississippi will see an increase in cases if people stop wearing face coverings,” said Dr. Amesh Adalja with the Johns Hopkins University Center for Health Security.Infectious disease experts remind people just because an order may be lifted, doesn't mean they should stop wearing masks.“We have to have an effective vaccine to prevent people from getting infected as well as prevent them from getting severe disease, that we had adequate testing capacity so people could know their status and wouldn't go out into public if they were positive,” said Adalja. “I think short of that, masks are going to be one tool that we have to continue to use and many people are going to get accustomed to masks and they're going to realize that masks also likely have some impact on other respiratory viruses, so we may see mask wearing much more common in the United States, similar to what it is in other Asian countries, because of the value people are gaining from them.”New research on homemade cloth masks found they expel invisible cotton fibers into the air. It’s unknown if those fibers can carry infectious viral particles, which drives home the point of washing any cloth facial coverings. Make sure you do that regularly. 1580

As the debate over police defunding wages on in parts of the country, officials in Albuquerque, New Mexico have found a middle ground.Mayor Tim Keller recently introduced a plan to strip the police department of million each year to help create and fund a new department that would respond to certain 911 calls instead of police.He says the city is the first in the country to do this."It’s a public health approach to public safety,” said Keller.The new department would consist of service workers, public health personnel, and specialists who would respond to calls related to homelessness, mental illness, and drug overdoses."For modern history, every city has said we’ll either send police or fire,” said Keller. “It’s about restructuring, institutionally, how we respond.”"We’re not the experts. We go over there and a lot of times our officers don’t know what to do,” added Albuquerque Police Chief Michael Geier.Geirer says the introduction of the new department comes as a relief. His police department is already short-staffed with officers, so handing these calls off to specialized personnel would not only help his department but the public.“We’ll be able to handle the higher-priority calls, and then our response time, and our community engagement," he said. "There will be more trust in the community.”Greier says, to a degree, the Albuquerque Police Department has already started delegating certain calls to the fire department and it has spared officers from responding to nearly 15,000 calls in just the last few months--many of which could keep an officer on scene for hours.“We want to get past responding to the symptom of the root cause,” said Albuquerque Chief Administrative Officer Sarita Nair. “We want to get down to that root cause and start addressing issues there.”Mayor Keller says the move to create the new department was only made recently, so there will be substantial planning and public input before it actually goes into effect. 1979

ATLANTA — The funeral for the late civil rights icon and congressman John Lewis will be held Thursday at Atlanta’s historic Ebenezer Baptist Church, which the Rev. Martin Luther King Jr. once led. Lewis’ family announced that the funeral will be private, but the public is invited to pay tribute over the coming days during a series of celebrations of Lewis’ life beginning Saturday in his hometown of Troy, Alabama. Ceremonies will also be held in Selma, Alabama, and his body will lie in state at the Alabama State Capitol in Montgomery, the Georgia State Capitol in Atlanta and the U.S. Capitol in Washington.Lewis, 80, died Friday after a six-month battle with pancreatic cancer. He represented Georgia as a Congressman for more than 30 years, winning 17 elections. He also fought for Civil Rights for Black people in the 1960s, originally gaining notoriety as one of the 13 original "Freedom Riders." 914

Automakers are racing to develop driverless cars, putting increasingly complex technology on the road despite concerns from safety experts and the National Transportation Safety Board about a lack of regulations.Unlike rules for the design of a seatbelt or airbag, the federal guidelines for automated vehicle systems are voluntary. The U.S. Department of Transportation says keeping rules at a minimum will speed up the introduction of life-saving technology, a goal made all the more urgent as traffic deaths climbed again last year to 37,461, with 94 percent of those caused by human error.That lack of mandatory rules for self-driving cars has given automakers and technology companies the green light to police themselves, said Jackie Gillan, president of Advocates for Highway and Auto Safety. The group is calling for the government to issue mandatory safety standards for driverless cars.“Before we introduce this technology we need to have some assurance and accountability by the industry that this technology is not going to kill or injure consumers,” Gillan said.The National Transportation Safety Board makes recommendations after investigating major transportation incidents. The board recently called on DOT to issue new safety rules after its investigation of a May 2016 fatal crash of a Tesla Model S operating on autopilot near Williston, Fla. The Tesla slammed into a tractor-trailer, its cameras and automatic emergency braking system failing to spot the blank side of the truck against the white sky.It was the first known deadly wreck of a car driving with that level of automated sophistication. The NTSB said the driver relied too heavily on the car’s traffic-aware cruise control system and autosteering feature, but also blamed Tesla’s autopilot for allowing the driver to not interact with the car for prolonged periods of time.Investigators found the driver had his hands on the wheel for only 25 seconds during the 37 minutes the car was on autopilot. After the crash, Tesla updated its software that requires drivers touch the wheel every so often when the car is driving itself to ensure a human is paying attention to the road. Now if a driver repeatedly fails to touch the wheel, he or she will “strike out” and cause the car to slow down and stop in its lane with its hazard lights on, disabling autopilot for the remainder of the trip. 2378

Authorities will begin distributing an experimental Ebola vaccine in Mbandaka, a major city in the Democratic Republic of Congo, on Monday to try to stop the spread of the deadly virus.Healthcare workers in Mbandaka, the capital of Equateur Province and home to 1.2 million people, will be the first to receive the vaccine, World Health Organization spokesman Tarik Ja?arevi? said.The confirmation of the first case in Mbandaka last week has raised concerns that the virus could spread faster than expected. So far, 26 people have died in the outbreak, according to the WHO.The vaccine, called rVSV-ZEBOV, will likely be distributed to some 8,000 to 10,000 people in its first phase, Peter Salama, deputy director-general of emergency preparedness and response at the WHO, said Friday.It will be given to people who have had contact with people infected with Ebola and contacts of those contacts, Salama said.Ebola is an incredibly contagious virus which causes the sudden onset of symptoms including fever, fatigue and muscle pain within two to 21 days after infection. Patients suffer vomiting, rash and diarrhea, impaired kidney and liver function -- and in some cases internal and external bleeding.An outbreak in 2014 in West Africa killed more than 11,000 people in months. 1287
