A major warning from scientists around the world: Do not depend on antibodies for permanent immunity from COVID-19. This comes on the heels of several studies showing that antibodies only last in our bodies for about two to three months.“That’s normal,” said Dr. Michael Teng, a professor at the University of South Florida's College of Internal Medicine and a researcher.According to Dr. Teng, our immune system creates antibodies when a virus enters our bodies. Their main purpose is to stop the virus from getting into our cells. Having few or no antibodies isn’t necessarily a bad thing, and it doesn’t mean you’ll be reinfected with the virus right away.“Antibodies are supposed to go down after a while,” Dr. Teng said. “You’re not supposed to have high elevated levels of antibodies for weeks on end. It’s not normal.”Scientists were hoping the antibodies produced from COVID-19 would stick around as long as antibodies produced from other forms of coronavirus, like SARS. Now that studies have shown that they don’t, they say we should rely on treatment, and working to come up with a vaccine.There are several potential vaccines being tested right now, but don’t expect to get your hands on one any time soon.“The fastest vaccine that we ever made was the Mumps vaccine and that took four years,” said Dr. Teng. WFTS' JJ Burton first reported this story. 1386

A Union Pacific train hauling lumber and other chemicals derailed and caught fire early Wednesday morning while crossing a bridge over Tempe Town Lake, which caused a portion of the bridge to collapse.More than 90 firefighters from the Tempe Fire Department and other nearby agencies responded to the southern portion of Tempe Town Lake where they found several train cars on fire. Flames could be seen running the length of the bridge, sending dark clouds of smoke billowing into the air near Tempe Beach Park.Several firetrucks were seen spraying water on the flames for several hours Wednesday morning, while a fireboat was helping to spray water onto the flames and remnants of the fire from the lake.Tim McMahan, a spokesperson for Union Pacific Railroad, said in an email that eight to 10 train cars were reported to be on fire. He said none of the train's crew were injured, but said one person was treated for smoke inhalation. When the south side of the bridge collapsed, three tank cars fell below it. Two of those cars were hauling cyclohexane and the other was hauling a rubber material, McMahan said in an email. Cyclohexane is a class ii combustible liquid that smells like acetone or peppermint, according to the CDC's website.McMahan said none of the three tanks were involved in the fire and were not believed to be leaking any material.As a result of the investigation, several roadways near Tempe Town Lake, including portions of the Loop 202 Freeway, have remained closed throughout much of the day. Tempe Beach Park is also closed. All classes and boating activities were quickly canceled, the City of Tempe said in a news release. Valley Metro has also terminated its eastbound service at 38th Street and Washington and westbound at Smith-Martin and Apache. It used buses to re-route passengers between those two stops, operators said in a tweet.The light rail does not use the bridge that collapsed. The track where the bridge collapsed is mostly used for cargo trains, McMahan said. Service Alert-Update: Due to a heavy rail fire in Tempe, Valley Metro is terminating service eastbound at 38th St/Wash and Smith Martin/Apache Blvd in Tempe.

My Mom, the one and only, Maggie Griffin, passed away today. Hours ago. I am gutted. She was my best friend. She was my family. You knew her. She appreciated you guys so much. I’m shaking. I won’t ever be prepared. Her point of view. So unique. We just GOT each other. I’m so grateful you got to be part of her life. You loved her. I know it. She knew it. She’s irreplaceable. I’m telling you right now, I am not doing well with this. I’m rambling now. Sorry. It truly feels like the end of an era. Oh, and OF COURSE she went on St Patrick’s Day. I love you guys. KG 582

Four kids were removed from a Phoenix home after one child died, and the other children were found with "insects crawling out of their ears." Phoenix police report that on January 7, they responded to a home for an unresponsive child. Phoenix Fire Department paramedics pronounced the 1-month-old boy dead at the scene around 11 p.m. Police say there were a total of five children in the home at the time, two 1-month-olds, a 1-year-old, 4-year-old, and 6-year-old. While police were there, the other 1-month-old child began to have trouble breathing. The child was taken to the hospital where it was found to have "traumatic head injuries," and a brain bleed. The Department of Child Safety removed the other three children from the home. During their evaluation, the other children were found "to have a lice infestation, covered in dirt, extremely soiled diapers, and insects crawling out of their ears." The 1-year-old was also found to have multiple skull fractures. The 4-year-old child later reportedly told investigators that "Dada," 38-year-old Donald Roy Ferguson, threw the baby, who later died, to the ground. An autopsy report did not find any deadly traumatic injuries, but additional medical tests are being done. During their investigation, police say Ferguson was watching the children while their mother, 29-year-old Emmaline Amelia Ramirez, was out getting baby items. Ferguson called her to return home when the baby was choking. Ramirez allegedly returned home and gave the child CPR, and reported he was fine, according to Ferguson. She then ate and went to bed. Around 10:30 p.m., the child stopped breathing again, and Ramirez performed CPR and called 911. Ferguson later admitted to becoming angry and hitting Ramirez, according to court records. Ramirez also allegedly told police that when Ferguson hits her, the children cry and hide under the bed. According to court records, there have been several prior DCS reports of abuse in the home.The couple has been charged with seven counts of child abuse. This article was written by Joe Enea for 2091

Bubba Wallace has found his voice as an activist. He hopes to bring more Black fans into NASCAR as he emerges as a leader in the sport. He would like some of his newfound fame to lead to an influx of sponsorship to fund the No. 43 Chevrolet for Richard Petty Motorsports. He’s grateful NASCAR released the photo of the rope found in the speedway garage stall. NASCAR President Steve Phelps stated “the noose was real” as it concluded its investigation. Wallace says he is bothered that “somebody still knows how to tie a noose."In an interview with reporters on Friday, Wallace was asked about a Confederate flag being flown over the track on Sunday. “It’s the right for peaceful protests,” Wallace said. “It’s part of it. But you won’t see them inside of the race tracks where we’re having a good time with the new fans that have purchased their tickets and purchased their favorite driver’s apparel. You won’t see it flying in there. Outside, they’re just going to be making a lot of noise. It’s part of it. It’s exactly what you see on the flip side of everything going on in cities as they peacefully protest. But we won’t see cops pepper-spraying them and shooting them with rubber bullets, will you?”Wallace's crew reported on Sunday finding a noose hanging from a garage stall at Talladega Superspeedway.Before Monday's race, drivers and crew members stood in solidarity with Wallace. Fellow drivers pushed Wallace’s car to the front of the field moments before the race got underway.Wallace became the first Black full-time NASCAR Cup Series driver in 2018 in more than four decades. He instantly found success as a full-time driver, finishing as the runner-up of the 2018 Daytona 500.Amid national unrest over the death of George Floyd, Wallace called for the ban of Confederate symbols from NASCAR events. NASCAR announced two weeks ago that Confederate flags would no longer be permitted at its tracks.Despite the ban, multiple Confederate flags were seen flying outside of the raceway, according to photos shared by the Associated Press. 2073
