Slowly but steadily, caravan migrants who trekked across Mexico are pleading their cases to US authorities on why they should be granted asylum.Nearly half of them have now been accepted to begin processing by US authorities at the border with Mexico, Alex Mensing -- whose group, Pueblo Sin Fronteras, organized the caravan -- said Wednesday.Caravan organizers said 49 Central American migrants began asylum processing on Wednesday, bringing the total of those accepted for processing to 74.On Tuesday, 17 Central American migrants were taken in by US Customs and Border Protection (CPB) for asylum processing, said Viridiana Vidal, whose group Pueblo Sin Fronteras organized the caravan.The group was predominately made up of mothers and their children.However, CPB says it processed 28 between Monday and Tuesday. Figures for Wednesday were unavailable. 864

Someone just had to spoil the party.The Beyoncé/Jay-Z spectacle that is "On the Run II" was wrapping up its Saturday night stop in Atlanta when a man ran up on stage and bolted after the couple.He actually got close enough to, as police put it, push Jay-Z -- but the entertainer and his wife are fine.The incident made for one final "what just happened?" moment to close out a show that already had plenty of "what just happened?" moments (albeit, of the good kind).Here's what happened:The Carters were walking off the stage, after tag-teaming through two-and-a-half hours of their respective back catalogs at Atlanta's Mercedes-Benz Stadium. The last few strains of "Apesh*t" were closing out the show with a bevy of dancers doing their thing. 753

ST JOSEPH, Mo. — A couple rushed to save a dog’s life after she was shot and left for dead in the woods.Jacob Carter, his fiance Robin Musser, and a few other family members were out hunting for mushrooms Thursday in the Bluffwoods Conservation Area just south of St. Joseph, Missouri.The group was just finishing up when they heard gunshots."We heard two gunshots, and we were coming on out anyway and stuff, getting ready to pack up and leave,” said Carter.Musser said the gunfire didn’t worry them since it’s common during turkey hunting season. "We'd seen a turkey earlier, thought maybe someone was shooting at the turkey,” she said.As they were driving out of the woods, something caught Musser’s eye."We were coming down the road and I spotted the dog and thought it was a puppy,” said Musser.Carter pulled over to go see if the dog was okay.As he walked closer he noticed it was an adult dog that wasn’t moving, and then he saw blood."That's when I noticed that she was shot, so I took my shirt off and started applying pressure,” said Carter.The white female pitbull had been shot twice, once in the back of the head and once through her ear. 1184

Some types of oat cereals, oatmeal, granola and snack bars contain higher levels of a chemical found in the weed killer Roundup than what the Environmental Working Group considers safe, according to a report released Wednesday by the advocacy group.Almost three-quarters of food samples tested showed higher glyphosate levels than what the group's scientists believe to be "protective of children's health," the report indicates.Last week, a jury at the Superior Court of California in San Francisco awarded 9 million in damages to a groundskeeper whose attorney argued that Roundup, a weed killer made by Monsanto, caused his terminal cancer."We will appeal this decision and continue to vigorously defend this product, which has a 40-year history of safe use and continues to be a vital, effective and safe tool for farmers and others," Monsanto Vice President Scott Partridge said in a statement at the time."More than 800 scientific studies, the US EPA, the National Institutes of Health and regulators around the world have concluded that glyphosate is safe for use and does not cause cancer," Partridge said. 1125

Some of the COVID-19 vaccine candidates call for more than one shot, so how do we make sure patients come back?Three experts all tell us preparing people for the side effects will be critical.A nursing researcher described those side effects in a JAMA article. She suspects she had the experimental vaccine as part of Pfizer’s Phase III clinical trials.After the second shot, she said she was light-headed, nauseous, had a headache, ran a fever, and was hardly able to lift her arm from muscle aches. She wasn't warned and it scared her into thinking she might have COVID-19.“The immune system is revving up,” said LJ Tan, Chief Strategy Officer at the Immunization Action Coalition. “It's responding to that vaccine, and I think we need to tell our patients that so that they expect that. Otherwise, they're going to say, ‘wow that thing hurt, I'm not coming back for that second dose.’”For comparison, a recent shingles vaccine also requires more than one dose and can be painful. Providers and advocates lead education efforts on what to expect. The return rate after the first shot for shingles is about 80%, which is considered high.One suggestion is to put information on side effects in COVID-19 vaccine distribution kits.The Centers for Disease Control and Prevention (CDC) has already said it plans to include index cards that tell patients what they had and when their next dose is due. That's on top of electronic reminders like email or texts.The federal government has also promised to cover most costs for the vaccine.One doctor says he'd take that a step further.“I feel extremely strongly that we should do everything we can in terms of customized, personalized patient support programs, and even recommend that the federal government go beyond free and provide small rewards or incentives for people who complete the two-dose program,” said Dr. A. Mark Fendrick, Director of the University of Michigan's Center for Value-Based Insurance Design.There's some protection for people who only get one dose of the Pfizer vaccine, but nearly full protection is better. The second dose also boosts antibodies.“That's important because of waning immunity. The higher your antibodies when you start, the longer it takes for that to decrease over time, and potentially make you more susceptible,” said Dr. Gregory Poland, Director of the Mayo Clinic's Vaccine Research Group.That means the best thing is to get both doses as was tested in the study. 2463
