Bacteria often get a bad rap, which is fair—they are responsible for diseases like strep throat, pneumonia, and tuberculosis, and antibiotic resistance is a legitimate threat to humanity's existence. But some bacteria might actually save lives by cleaning up things like massive oil spills and radioactive waste. Featuring Dr. Cara Santelli.

Polymer membranes make everything from rain jackets to medical devices. But they’re also integral parts of hydrogen fuel cells, powering cars that give off nothing but water vapor. How do fuel cells work, and why aren’t you driving one yet? Solutions is made with funding and featuring scientists from 3M, Ascend Performance Materials, Baker Hughes, BASF, Dow, DuPont, Procter & Gamble, PPG, Royal DSM, SABIC, Solvay, and W. L. Gore & Associates, none of whom influenced any editorial decisions.

When you hear the word “molasses” you probably imagine super slow-moving, brown-colored sweet stuff that you add to a cookie recipe. And that is what molasses usually looks like, but under certain conditions and in large enough quantities, molasses can be dangerous. Just over a century ago, the North End of Boston learned just *how* dangerous.  Featuring Alex Dainis, PhD and Nicole Sharp, PhD

Sweat is this thing that many of us seem to loathe, but also pay a lot of money to do while being yelled at by professionals. So what is sweat? And why do we do it? And why are we often so embarrassed by it? This episode features writer Sarah Everts, who recently wrote a book called The Joy of Sweat: The Strange Science of Perspiration.

In 2020, researchers discovered that more than 1,000 tons of plastic—that’s over 100 million plastic water bottles worth—rains down on National Parks and wilderness in the western U.S. every year. How is that possible? This week's episode features microplastics researcher Imari Walker. Check out her YouTube channel here: https://www.youtube.com/channel/UCoiqwAaGW6-xANs3XOCO_Pg

Sam Kean's latest book, The Icepick Surgeon: Murder, Fraud, Sabotage, Piracy, and Other Dastardly Deeds Perpetrated in the Name of Science, dropped earlier this week. It’s about when knowledge becomes everything—the only thing. At whatever the cost. You'll hear about what made Sam want to write the book, and about a couple of the characters within its pages. You can find the book here: https://www.littlebrown.com/titles/sam-kean/the-icepick-surgeon/9781549102929/

How do you keep moths from munching on apples? By confusing them with a field full of mating pheromones brewed in a lab. The same fermentation strategy can also make enzymes to help chickens digest their feed and keep their farmyards a little less… sticky. Today we’ll talk about the biochemistry that helps food make it from the field to your fridge without getting eaten first!

 A lot has happened in the last year (understatement of the millennium), so we wanted to bring our listeners something a bit sillier than usual. In this episode we’re talking food and drink chemistry—just fun bits of trivia that you can take with you as you venture back out to bars and restaurants this summer. Sam's joined by Orbitals executive producer George Zaidan (as promised in the episode, you can see his hot pepper struggle here: https://www.youtube.com/watch?v=8R98O29Fs7s)  Featuring Matt Hartings, PhD and Selina Wang, PhD

Vaccines help our immune system to learn to recognize invading pathogens before we ever get infected. But some vaccines include molecules that act like an extra alarm system, alerting our immune cells to pay attention! These molecules are called adjuvants, and scientists are working on creating new ones that could help create vaccines against pandemics that haven’t even happened yet!

Over half a million people in the US have died from an opioid overdose over the last 20 years, and a lot of the time they were prescribed those opioids by a doctor. So what makes these drugs so dangerous? And if we know they can be this dangerous, why are they still prescribed?  This month’s episode is about opioids—their history, their use, and the research that might help us emerge from this epidemic. Featuring opioid researcher Kelly Dunn, PhD
