April is Citizen Science Month! It’s a chance for everyone to contribute to the scientific process—including collecting data, taking observations, or helping to analyze a set of big data. And best of all, a lot of these projects can be done wherever you happen to be personally isolating. Caren Cooper, an associate professor at North Carolina State University in Raleigh and co-author of the new book A Field Guide To Citizen Science: How You Can Contribute to Scientific Research and Make a Difference, joins Ira to talk about what makes a good citizen science project, how to get involved, and suggestions for projects in all fields of science. Cooper is also the project leader for the citizen science project Crowd The Tap, looking at mapping water infrastructure and the prevalence of lead pipes throughout the country.

Mercury is the smallest planet in the solar system and the closest to the sun. The temperature there can reach up to 800 degrees, but the planet is not an inert, dry rock. Scientists recently found water ice at the poles of the planet, and another team found possible evidence for the chemicals building blocks of life underneath Mercury’s rocky terrain—a landscape pitted with impact craters and haphazardly strewn hills. Those results were published in the journal Scientific Reports. Planetary astronomer Deborah Domingue takes us on a planetary tour and talks about what Mercury can tell us about the rest of the solar system. All sorts of COVID-19 treatments have been proposed, but some are more promising than others. One of these experimental treatments is using the blood plasma from recovered patients to infuse antibodies into those who are currently sick. This week, New York put out a call for plasma donations, becoming the first state to attempt this approach. Sarah Zhang of The Atlantic talks about what we know about the effectiveness and hurdles of this type of treatment. She also discusses the second wave of COVID-19 infections hitting Asia, and the CDC’s changing stance on personal face mask usage. Subscribe to this podcast.
