Scientists are reporting that the antibodies people make to fight the new coronavirus do not fade quickly. The new study is the most extensive work yet on the immune system’s response to the virus and is good news for efforts to develop vaccines. The report published Tuesday in the New England Journal of Medicine. It was based on tests on more than 30,000 people in Iceland. It found antibodies lasted for at least four months after diagnosis. The study also found that more severe cases of the coronavirus led to a stronger immune response to the virus."Among recovered persons, antibody levels are higher in older persons and in those more severely affected by SARS-CoV-2 infection," according to the research. Independent experts say if a vaccine can spur production of long-lasting antibodies like that, it gives hope that immunity may not be fleeting. That's what some smaller studies previously suggested.While the research was promising, it did also find that Icelanders are vulnerable to a second wave of the coronavirus even with the number of potentially immune citizens. 1092

SCOTTSDALE, AZ — Emergency crews have recovered a body after an incident at a Scottsdale aquatic park.Crews were at Eldorado Aquatic Park near Hayden and McDowell road early Monday morning.Scottsdale police say around 12:30 a.m.; an officer was making rounds in the area when he heard what sounded like muffled calls for help.He worked to locate where the calls may be coming from and eventually found them to be coming from a pipe that helps support one of the water slides.Officers were communicating with the victim, said to be a transient, but lost communication with him around 2 a.m.Officials say the man reportedly went up over a tall fence surrounding the park and was up on the slide. He then somehow fell into the pipe structure, where he became trapped.Crews had to dismantle the slide in order to get the victim's body out.He has since been identified as 31-year-old Ryan Kelly. A medical examiner will determine Kelly's official cause of death.This story was originally published by Ashley Loose on KNXV in Phoenix. 1037

San Francisco police say they will stop releasing the mug shots of people who have been arrested unless they pose a threat to the public. Police Chief Bill Scott says the new policy starting Wednesday is aimed at stopping the spread of negative stereotypes of minorities. Jack Glaser, a public policy professor at the University of California Berkeley who researches racial stereotyping, says data shows Black people who are arrested are more likely to have their cases dismissed by prosecutors. But the mug shots live on. That contributes to Americans making an unfair association between people of color and crime. 624

SAN FRANCISCO (AP) — The robotic car company created by Google is poised to attempt a major technological leap in California, where its vehicles will hit the roads without a human on hand to take control in emergencies.The regulatory approval announced Tuesday allows Waymo's driverless cars to cruise through California at speeds up to 65 miles per hour.The self-driving cars have traveled millions of miles on the state's roads since Waymo began as a secretive project within Google nearly a decade ago. But a backup driver had been required to be behind the wheel until new regulations in April set the stage for the transition to true autonomy.RELATED: 2018 could be a pivotal year for driverless carsWaymo is the first among dozens of companies testing self-driving cars in California to persuade state regulators its technology is safe enough to permit them on the roads without a safety driver in them. An engineer still must monitor the fully autonomous cars from a remote location and be able to steer and stop the vehicles if something goes wrong.California, however, won't be the first state to have Waymo's fully autonomous cars on its streets. Waymo has been giving rides to a group of volunteer passengers in Arizona in driverless cars since last year. It has pledged to deploy its fleet of fully autonomous vans in Arizona in a ride-hailing service open to all comers in the Phoenix area by the end of this year.But California has a much larger population and far more congestion than Arizona, making it even more challenging place for robotic cars to get around.RELATED: NTSB report: Uber self-driving SUV saw pedestrian in Arizona but didn't brakeWaymo is moving into its next phase in California cautiously. To start, the fully autonomous cars will only give rides to Waymo's employees and confine their routes to roads in its home town of Mountain View, California, and four neighboring Silicon Valley cities — Sunnyvale, Los Altos, Los Altos Hills, and Palo Alto.If all goes well, Waymo will then seek volunteers who want to be transported in fully autonomous vehicles, similar to its early rider program in Arizona . That then could lead to a ride-hailing service like the one Waymo envisions in Arizona.But Waymo's critics are not convinced there is enough evidence that the fully autonomous cars can be trusted to be driving through neighborhoods without humans behind the wheel.RELATED: Potential "game changer" could make commutes more relaxing"This will allow Waymo to test its robotic cars using people as human guinea pigs," said John Simpson, privacy and technology project director for Consumer Watchdog, a group that has repeatedly raised doubts about the safety of self-driving cars.Those concerns escalated in March after fatal collision involving a self-driving car being tested by the leading ride-hailing service, Uber. In that incident, an Uber self-driving car with a human safety driver struck and killed a pedestrian crossing a darkened street in a Phoenix suburb.Waymo's cars with safety drivers have been involved in dozens of accidents in California, but those have mostly been minor fender benders at low speeds.RELATED: Waymo self-driving car crashes in ArizonaAll told, Waymo says its self-driving cars have collectively logged more than 10 million miles in 25 cities in a handful of states while in autonomous mode, although most of those trips have occurred with safety drivers.Waymo contends its robotic vehicles will save lives because so many crashes are caused by human motorists who are intoxicated, distracted or just bad drivers."If a Waymo vehicle comes across a situation it doesn't understand, it does what any good driver would do: comes to a safe stop until it does understand how to proceed," the company said Tuesday. 3827
