Where Did The Word ‘Vaccine’ Come From? As we head into 2021, there’s one word on all of our minds: Vaccine. It may be in headlines right and left these days, but the word was actually coined more than a century ago.  In the 1700s, smallpox seemed unbeatable. People tried all sorts of things to protect themselves, from taking herbal remedies to tossing back 12 bottles of beer a day. Nothing worked.  Then Edward Jenner, an English doctor, heard a rumor about a possible solution. It wasn’t a cure, but Jenner thought he might be able to stop smallpox infections, before its dreaded symptoms began. One spring day, with the help of a milkmaid, an eight-year-old boy, and a cow named Blossom, he decided to run an experiment.  In this segment, Science Diction host Johanna Mayer tells the story of that ethically questionable, but ultimately world-altering experiment, and how it gave us the word “vaccine.” New Year, New Birds This year’s Audubon Christmas Bird Count is anything but usual: Since gatherings are unsafe, it’s up to individuals to count what they can, where they are. But eager birders are still out there counting crows, chickadees, and grosbeaks in the name of community science. Ira joins a flock of bird nerds—Audubon’s Geoff LeBaron and Joanna Wu, and author and nature photographer Dudley Edmondson—to talk about the wonders of winter birding, and what decades of data show about how birds are shifting in a warming, changing world. Plus, how to make the most of birding while sheltering in place. Birds Of A Feather: Making Science More Inclusive It’s been six months since Black birders took over Twitter in solidarity with New York City birder and science writer Christian Cooper, who posted a video of a white woman threatening to call the police on him the very same day that George Floyd was killed by police in Minneapolis. In response, Black naturalists and birders celebrated their communities and told stories about similar harassment in the outdoors for #BlackBirdersWeek. Other Black scientists have held their own visibility campaigns with #BlackInNeuro, #BlackInAstro, and dozens of other disciplines. SciFri producer Christie Taylor talks to herpetologist Chelsea Connor, a co-founder of Black Birders Week, about her relationship with the outdoors, and what comes next for creating, and maintaining, spaces where Black scientists can thrive.
