Behind The FDA’s Decision To Vaccinate Kids Under 12 This week, Pfizer’s COVID-19 vaccine for kids under 12 was officially recommended by the CDC, after a unanimous vote from its independent advisory committee and the FDA’s authorization based on safety and efficacy data. In their analysis, the FDA said the benefits of the vaccine “clearly outweigh” the risks. The risks, which were referenced in a cost-benefit examination of the data, included circumstances that popped up in the study that were unrelated to getting the vaccine (like a broken arm and an accidentally swallowed penny that occurred during the observational period). As parents around the U.S. race to find appointments, Ira talks to science journalist Maggie Koerth about the safety data and what’s next for parents of young kids, including those under 5. They also discuss a NASA test of a system to defend the planet from killer asteroids, a new prediction that climate change will change the availability of food crops within the next ten years, and other science news headlines. What’s Next For Kansas After 20 Years Of Wind Power? The wind farm business in Kansas has hit its awkward adolescence. It’s still growing 20 years in, but unsure what the near future might hold. If it wants to get through those tough years and continue to grow, it needs to find more workers, to figure out what to do with the dated-but-not-obsolete turbines erected two decades ago and to sort out a way to carry all that wind-harvesting muscle beyond the state’s borders. Consider the burly, newest version of wind farming at the Cimarron Bend wind farm south of Dodge City. “We just watch and listen to the towers,” said project supervisor Dewain Pfaff, who’s responsible for keeping about 300 turbines up and running. “If you can hear a noise we want to mitigate those issues as soon as possible.” Standing at the base of one of the newest turbines on the site, he’s dwarfed by the tower that rises 300 feet into the air. That’s almost as tall as the Kansas State Capitol. Add in the blade when pointing straight up and it’s taller than the tallest building in the state. That mammoth size is one way wind turbines have changed over the past 20 years. While the turbine is nearly 300 feet tall, the turbines at the very first large-scale wind farm in the state stretched only 200 feet above the ground. Transporting larger towers and blades is trickier, but inevitable. Read the rest at sciencefriday.com. SciFri Reflects On Three Decades Of Covering Science News Thirty years ago this week, on Nov 8, 1991, the first episode of Science Friday aired as part of NPR’s “Talk of the Nation” series. After 30 years, over 9,000 interviews, and several changes of distributors, offices, and studios, the program is still going strong. In this segment, host and executive producer Ira Flatow and SciFri director Charles Bergquist reminisce about some of the great guests and listener questions they’ve heard over the course of the program—from the very first episode, featuring the late Nobel Laureate Sherwood Rowland talking about the ozone hole, to a young fan helping to celebrate SciFri’s Cephalopod Week with her own ode to an octopus. Plus, moments with Jane Goodall, Sylvia Earle, astronaut Leland Melvin, the late Carl Sagan, and more. Subscribe to this podcast.
