What The If?

Ever wonder what would happen if life got flipped in a molecular mirror? In this episode, we explore the fascinating possibility of creating mirror-image life forms. Picture bacteria with every molecule backwards - like they've been pulled through the looking glass! Our immune systems would be totally confused, like trying to read a book reflected in a spoon. These backwards bugs would need their own special backwards food, and might create their own unique mirror-world ecosystem alongside our regular one. From double-helix DNA that spirals the wrong way to proteins that do everything in reverse, discover the weird and wonderful world of molecular mirror images and how they could create a second tree of life right here on Earth. Based on the New York Times article "A Second Tree of Life Could Wreak Havoc, Scientists Warn" by Carl Zimmer (December 12, 2024) https://www.nytimes.com/2024/12/12/science/mirror-life-microbes-research.html?unlocked_article_code=1.iE4.DJDO.CQlOrQ-08aNQ&smid=url-share --- Find out more about Gaby's science fiction short story!

Google's DeepMind has shattered a long-standing barrier in weather forecasting, achieving reliable 15-day predictions that were previously thought impossible due to chaos theory. Traditional fortune tellers are nervously updating their résumés as AI tackles the age-old question: if we can predict the weather two weeks out, what else can we predict? From knowing which baseball team will win before the first pitch to figuring out if you'll actually remember your briefcase tomorrow morning, explore how increasingly accurate predictions could reshape our understanding of choice, destiny, and whether you really had any choice about reading this description at all.

Here's our Bonus show, "Beyond The IF" which we record each week for our Patreon supporters. I'm sharing it here so you can get a taste of what it's like. If you're not a Patreon supporter, you can learn more about the benefits available to all our wonderful members at patreon.com/whattheif. On this week's bonus after-party show... What starts with toilet water and ends with dissolving takeout containers? We began with Singapore's recycled water beer at COP29 and found ourselves exploring everything from Massachusetts' fancy locking compost bins to New York's experimental waste programs. The conversation flowed through the surprisingly dramatic history of why we ditched glass for plastic (spoiler: it wasn't for the planet), and landed us in the world of disappearing food containers and compostable bags that actually break down instead of sticking around for a few centuries. We thank all our Patreons for supporting our weekly adventures through science, even when they start in unusual places. Wishing you all a wonderful Thanksgiving filled with good food, warm company, and minimal food waste. May your compost bins be full and your recycling sorted correctly! Cheers, Philip

What happens when your toilet water gets a career change and becomes a craft beer? At COP29 in Azerbaijan, Singapore's showing off exactly that with their hoppy pilsner made from recycled wastewater. Discover the fascinating world of water reclamation where sewage gets a spectacular makeover through advanced treatment systems. Learn how treatment plants transform waste into pure water through an incredible process involving bacterial helpers, sand filters, and high-tech purification. From delegates sipping recycled brew to a future where every drop of water might get a second chance, explore what our beverage scene could look like when we push sustainability to new limits.

We're excited to share a special treat with all our listeners - a "Beyond the IF" segment usually available only to our Patreon supporters! This bonus episode extends our fascinating conversation with Sharrona Pearl, author of "Do I Know You: From Face Blindness to Super Recognition." In this deeper exploration, we shift our focus to the opposite end of the face recognition spectrum - super recognizers. These individuals possess an extraordinary ability to remember and identify faces. But is this superpower all it's cracked up to be? We explore the daily challenges faced by super recognizers, from accidentally creeping people out to the art of pretending not to recognize everyone. Learn about the practical applications of this ability, including Scotland Yard's "super recognizer squad," and ponder the potential downsides that researchers have yet to explore. This glimpse into our "Beyond the IF" content showcases the kind of in-depth, mind-bending discussions our Patreon supporters enjoy regularly.
