As the COVID-19 pandemic rages on, your news feed is likely still overflowing with both breaking research and rumors. Virologist Angela Rasmussen of Columbia University joins Ira once again to Fact Check Your Feed, discussing everything from two vaccine trials’ hopeful early results to what antibody production might mean for long-term protection against the COVID-19 virus. They also discuss kids’ response to SARS-CoV-2—a topic of great interest to parents and educators trying to make plans for the coming school year—as well as the confusing terminology around ‘aerosol’ and ‘airborne,’ and research into mutations of the spike protein in one coronavirus variant. Recently, the European Space Agency’s Solar Orbiter satellite sent photos of surprising events on the sun’s surface. Scientists are calling these swirling areas “campfires,” though no one is quite sure what causes them. Joining Ira to talk about these new images is Anik de Groof, instrument operations scientist for the Solar Orbiter, based in Madrid, Spain. They talk about what kind of data the satellite is collecting, how COVID-19 impacted the mission, and what solar mysteries Anik is most excited to learn more about. This month, three different countries are launching missions to Mars—the first for The United Arab Emirates, China is sending an orbiter and a rover, and NASA’s Perseverance will join the Curiosity rover already on the ground. Amy Nordrum from MIT Technology Review talks about the science that each of these missions will be conducting. Subscribe to this podcast.
