Searching for Mars’ missing water
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, we talk to scientists about the latest research on Mars’s water and where they think the water went.
Reducing toxic metals in food
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, we explore the fallout from that report and renewed efforts to rein in the problem.
How research on aging could keep us healthier longer
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.
Nobel laureates Frances Arnold and Jennifer Doudna on prizes, pandemics, and Jimmy Page
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.
Historians pursue centuries-old chemical secrets—Green reading glass, Bologna stones, and Greek fire
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.
How will Biden’s election impact chemistry?
As we prepare for a new US president, many chemists are wondering how the administration change may affect them and their work. In this episode, 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.
