Spring is in the air, with flowers blooming and gardens starting. Most people with a green thumb will know a droopy plant is a signal that it needs water. But new research has found another way that plants will signal that they’re thirsty: emitting staccato popping sounds, too high pitched for the human ears. Elsewhere in the world of science journalism, an argument has been made that elephants have self-domesticated. If true, this would make these gentle giants only the third creature to have done this, alongside humans and bonobos. Joining Ira to talk about these stories and other science stories of the week is Rachel Feltman, host of the podcast “The Weirdest Thing I Learned This Week” and editor at large of Popular Science.
Your Future COVID-19 Vaccine May Come Through Your Nose
The nose knows about COVID-19 infection. It is the entrance to the immune system, after all. The nose’s position as one of our first lines of defense has many experts in favor of developing COVID-19 nasal sprays, with the thought that it may replace the needle jabs we’ve come to expect. The development of nasal vaccines comes at a time when many Americans are anxiously awaiting if the government will approve additional COVID-19 boosters. The bivalent boosters have been out for more than six months, and there have been reports the U.S. Food and Drug Administration will recommend an additional dose for some Americans this spring.
Joining Ira to give us the latest on nasal sprays, boosters, and answering some listener questions is Dr. Akiko Iwasaki, immunobiologist at Yale Medical School in New Haven, Connecticut.
Make It Easier To Be Green. Show Frogs Some Love
Frogs have been called the equivalent of the canary in the coalmine, harbingers for the health of our environment. When frogs go silent, something is amiss. So we’re going to spend some time talking about why frogs are so important and how you can better support your neighborly amphibians. One idea? Build a toad abode and welcome them in. Plus, there’s another way to help frogs and toads—and that’s by lending your eyes and your ears to the scientists who study them. April is Citizen Science Month, so we’re kicking things off with a toad-ally cool project called FrogWatch. It relies on volunteers from across the country to record frog calls and report them to FrogWatch’s database.
Ira talks with Dr. Itzue Caviedes-Solis, assistant professor at Swarthmore College, about making outdoor spaces more frog-friendly. Then, he chats with Carrie Bassett, National FrogWatch USA coordinator and education mission manager at the Akron Zoo, about how volunteers can lend their eyes and ears to help scientists study frogs.
Transcripts for each segment will be available the week after the show airs on sciencefriday.com.
