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.

Where do you take your career after you’ve won all of science’s biggest prizes? In this episode of Stereo Chemistry, C&EN executive editor Lisa Jarvis sits down with Nobel laureates Frances Arnold and Jennifer Doudna to hear about whether their career goals changed after they got that early-morning phone call in October and how the pandemic has shifted the way they approach their work.

Researchers want to invent the technologies of the future, but there are plenty of chemical questions lurking in the past. In this episode of Stereo Chemistry, C&EN assistant editor Gina Vitale joins host Kerri Jansen to explore the centuries-old secrets and nagging mysteries that keep science historians up at night—and how these researchers go about solving them. A script and additional resources are available at bit.ly/3qGGHg5.

As we prepare for a new US president, many chemists are wondering how the administration change may affect them and their work. Will President-Elect Joe Biden change immigration policies that have reduced the number of foreign students studying at US universities? How might scientific integrity standards in the federal government change under the Biden-Harris team? And will this administration grant the chemical industry’s wish to stop the trade war with China and other US trading partners? In this episode of Stereo Chemistry, C&EN policy reporter Cheryl Hogue joins host Kerri Jansen to help orient listeners to how a Biden administration is likely to impact the world of chemistry.

Many grad students may be surprised to learn their university’s policies for reimbursing medical fees for lab injuries do not cover grad students, or cover grad students only under certain circumstances. And it can be hard to get clarity on what is and is not covered. That’s left some grad students in an uncomfortable limbo of seeking answers after they’ve already racked up thousands of dollars in bills for an injury in the lab. In the latest episode of Stereo Chemistry, we uncover the source of this confusion and ask what—if anything—grad students can do about it.

Helium shortage 3.0 is winding down. But 2021 is likely to bring more changes to the global market for this critical, non-renewable gas. And even if there isn’t another crunch, scientists who use helium are tired of unstable supply of a material they need to keep their instruments running. In this episode of Stereo Chemistry, we’ll look at what’s behind the wobbly helium market and what scientists and instrument makers are doing to lift the heavy burden of helium use.

In August 2020, Black chemists and allies took to Twitter to celebrate the inaugural #BlackInChem week. The social media campaign highlighted the diversity and accomplishments of Black chemists at all stages of their career and also created space for candid discussions about the discrimination these scientists face in chemistry. In the latest episode of Stereo Chemistry, host Kerri Jansen and reporter Ariana Remmel hear from Black chemists from a variety of disciplines across academia and industry about the current state of diversity, equity, and inclusion in the chemical sciences and what non-Black allies can do to support Black chemists. Update 11/24/20: In response to listener feedback, C&EN has added an editor's note to this episode. View the note at bit.ly/361aFUR
