The continuing debate about children and vaccines can get pretty heated. One of the concerns is that vaccines weaken a baby's immune system against other diseases, but new findings should ease that fear           For many little ones, routine vaccinations are a rite of passage.  And sometimes, there can be a lot of them."Some parents are concerned that kids get too many vaccines in too short of a time," says Dr. Jason Glanz with the Kaiser Permanente Colorado Institute for Health Research. "So by the age of two children receive up to 10 vaccines and 26 shots and so that is a lot of shots."That's why Dr. Glanz and his team set out to see if getting that many vaccines was harmful."Thankfully our study show that it wasn't harmful," Dr. Glanz says.Dr. Glanz says many parents are concerned vaccines could overload their child's immune system and increase their risk of getting an infection in the future.The NOW's Kumasi Aaron asked Dr. Glanz, "Is there such thing as overloading an infant with vaccines?" "We did not see a list of that," Dr. Glanz replied. "We saw no evidence that receiving all the vaccines and receiving them on time in anyway damaged the child's immune system."The study looked at infants two years after they got those vaccines, and found they weren't likely to be more susceptible to other infections not targeted by those vaccines.Dr. Glanz says, "I'm hoping he provides some reassurance that these vaccines are safe and the benefits greatly outweigh the risks and that if they have any concerns that they should talk about it with the doctors." 1658

The decision to reintroduce gray wolves in Colorado will be decided by the people, and both sides of the issue say the decision will impact the entire country.“Only in 2020, the weird year that we are having would Colorado be voting to introduce a species that’s already here in Colorado,” said Shawn Martini, the vice president of advocacy for the Colorado Farm Bureau.“The western part of Colorado is primarily owned, and majority-owned, by the people as public lands,” said Rob Edward, who is part of the Rocky Mountain Wolf Project. “We all have interests on what happens on our public lands.”For centuries, the gray wolf roamed North America in large populations. But in the 1900s, the wolves were nearly hunted out of existence.The wild wolves haven’t lived in Colorado since 1940, and the U.S. Fish and Wildlife Service classified the animal as an endangered species in 1978.“They are the missing link in the Rocky Mountain chain,” Edward said. “From the high arctic to New Mexico, we can re-establish a population of wolves again by reintroducing wolves to western Colorado. The presence of wolves on those wild landscapes is important for the long-term health of those landscapes.”With Proposition 114 in Colorado, the people will be able to vote in November on whether this will become a reality. This is something that has never happened in the nation’s history.“Wolves are already all over the place,” Martini said. “They’ve come down from Wyoming and Montana through a natural process. We’re asking voters to say no to this ballot initiative, because it makes something a natural process into a political one.”Having people vote on this is something Martini is strongly against.“So, this the first time a species would be introduced into a state via a ballot measure,” Martini said. “The reason it’s never been done before because it’s a really bad idea to make a scientific process a political one. The Colorado Parks and Wildlife and biologists should be the ones making this decision, not voters who don’t always have access to the info and are not biologists and who don’t do this for a living.”The main reason wolf advocates like Edwards want to re-introduce wolves to the area is that they believe it could improve the ecosystem. In 1995, the gray wolf was reintroduced into the greater Yellowstone ecosystem to help manage the high population of elk. But that decision wasn’t voted on by the people.Biologists came up with a plan and brought it to Congress. After years of public comment, the secretary of the interior finally signed off on the project.“Colorado is not Yellowstone,” Martini said. “Yellowstone is subject to a ton of environmental regulations, so the people managing the area don’t have the same tools as Colorado does.”Regardless of what side people are on this issue, both sides agree that this a historic ballot measure that could change the course of the country ecologically and politically. 2941

The concept of universal basic income is getting new attention amid the COVID-19 pandemic. It’s the idea of giving out recurring payments to everyone without any strings attached.Stockton, California, has been testing this with 125 people, giving them 0 per month. They've been getting that money for more than a year and it was supposed to stop this summer, but the mayor extended the money until January because of the pandemic.More mayors are getting on board with the idea. Fifteen joined the organization Mayors for a Guaranteed Income. They're looking into launching pilot programs in their cities.We spoke with an economics professor who says the pandemic stimulus payments can be seen as a form of universal basic income.“Seeing that I think it must make the idea more real and at the same time it's pretty clear at this very moment why you might find this idea appealing,” said Ioana Marinescu, an assistant professor at the University of Pennsylvania. “That's because, again, a lot of people have lost income. There's a clear need for income security.”In the case of the stimulus checks, it's not people's fault they lost their income.With universal basic income, critics say people may not be deserving of the money. Marinescu believes the stimulus may be helping change the perception. She points to money people receive in Alaska from oil revenue. She says people aren't any less likely to work.In Stockton, they've found people are using the money for necessities like groceries and utility bills.How universal basic income, or UBI, gets funded is a big question.“One interesting thing that has happened with the stimulus checks is the idea that people had of saying it's going to be based right now on your past income and we'll potentially tax it away later after we're out of this hole,” said Marinescu. “So to me, that's a potentially important lesson for a potential UBI.”The president of the nonpartisan Center on Budget and Policy Priorities wrote that paying for universal basic income from new taxes isn't the way to go. He says we already need a lot of money to keep social security and Medicare going.Stockton's mayor says money from the pentagon budget or tax money from the legalization of marijuana could work. He's paying for his city's current pilot program with a grant and a private donation.Other cities looking to start pilots are considering forming public-private partnerships or working to find room in the city budget. 2467

  

The family of a 14-year-old Arizona boy with autism is demanding accountability after a Buckeye, Arizona police officer mistook the child for a drug user and detained him.On July 18, the boy, Connor Leibel, was forced to the ground by the officer and suffered multiple scrapes to his back, arm and face.The entire incident was captured on body camera, which was obtained by Scripps station ABC15. Watch the full raw video in the player above. Buckeye police officials did not immediately respond to requests for comment early Monday. In a statement by the Leibels' attorney, the family said they anguished over what happened and are demanding the city implement better training for its officers. “It’s astonishing that even after an internal investigation, the Buckeye Police Department claims it did absolutely nothing wrong,” the statement said. 861

  

The fossil of a large egg dating from the time of the dinosaurs has been found for the first time on the continent of Antarctica. In addition to its large size and unique location, this discovery is also challenging how scientists think about marine births millions of years ago.The details of the egg and its discovery were published this week in the journal Nature.The egg, measuring 11 inches long and 7 inches wide, was found back in 2011 by Chilean scientists, and sat in Chile’s National Museum of Natural History, labeled only as “The Thing.” David Rubilar-Rogers was one of the scientists who discovered the fossil and works at the museum. He reportedly showed it to every geologist who visited the museum, hoping someone could identify it. Julia Clark from the University of Texas at Austin visited in 2018.“I showed it to her and, after a few minutes, Julia told me it could be a deflated egg!” Rubilar-Rogers said. 933
