This month, Stereo Chemistry is sharing an episode of Third Pod from the Sun, a podcast from the American Geophysical Union, featuring an interview with retired astronaut and former professional athlete Leland Melvin. In the episode, Melvin describes how an early⁠—and explosive⁠—interest in chemistry grew into a scientific career at NASA and two missions to the International Space Station.

This month, Stereo Chemistry is sharing an episode of Orbitals that features an interview with forensic chemist Shari Forbes, an expert in human decomposition who studies the odors of decomposition at a body farm in chilly Quebec. Research at body farms—research facilities dedicated to studying what happens to human bodies after death—supplies law enforcement with valuable information about the process of decomposition in various scenarios. A transcript of this episode is available at bit.ly/3jdvLFN.

(Part 2/2) This month, Stereo Chemistry is sharing a pair of episodes from Distillations, a podcast from the Science History Institute. We rely on rare-earth elements to make many essential technologies like smartphones, medical imaging devices, and wind turbines. But how much do you know about where these extraordinary materials come from? In this two-part series, Distillations hosts Alexis Pedrick and Elisabeth Berry Drago explore the source of rare earths' "magic," the costs of acquiring these elements and what scientists are doing to try to find a way to produce them sustainably.

This month, we're sharing an episode of the podcast My Fave Queer Chemist. Hosted by graduate students Bec Roldan and Geraldo Duran-Camacho, the show celebrates the excellence of LGBTQ+ chemists everywhere. Stereo Chemistry is excited to share this recent episode featuring inorganic photochemist Irving Rettig. In the episode, Rettig discusses his background in art conservation, his experiences finding support and community in grad school, and his work promoting transgender-inclusive name change policies within academic publishing.

Note: This episode includes the use of slang terms for some members of the LGBTQ+ community. A transcript of this episode is available at bit.ly/3624azW. Follow My Fave Queer Chemist on Twitter at @MFQCPod. Find new episodes at anchor.fm/mfqc.

More than 50 years of missions to Mars paint a clear picture of a cold, dry, desert planet. And at the same time, photographs, minerals, and other data tell scientists that Mars once had as much water as Earth, or even more. Why are the two planets so different today? In this episode of Stereo Chemistry, we talk to scientists about the latest research on Mars's water and where they think the water went.

Listen to the end of the episode for an announcement about the future of Stereo Chemistry.

Toxic elements like lead, arsenic, mercury, and cadmium in food are not a new problem. But when they show up in pureed vegetables and other foods intended for babies, alarm bells go off. That's what happened in recent months following a bombshell congressional report that found neurotoxic metals in baby food from multiple manufacturers. In this episode of Stereo Chemistry, host Kerri Jansen and C&EN reporter Britt Erickson explore the fallout from that report and renewed efforts by baby food manufacturers, regulators, advocacy groups, and agricultural scientists to rein in the problem.

Living longer has been a human obsession for centuries, but while medical science has helped extend average life span, not all those extra years can be healthy. It turns out that aging is a major risk factor for disease. Follow along as host Kerri Jansen and reporter Laura Howes ask if instead of extending life span, we could extend health span and how modern science could make that a reality.
