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 wate...

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...

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. An...

Scientists have been naming ideas, theorems, discoveries, and so on after other scientists for a very long time (Newton's laws of motion, anyone?). Chemists are no different. They've been naming reactions after each other since about the early to mid 1800s. Nowadays, organic chemists in particular use them as a kind of shorthand. However, because the majority of name reactions honor white men, som...
