Flash Forward is a show about possible (and not so possible) future scenarios. What would the warranty on a sex robot look like? How would diplomacy work if we couldn’t lie? Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...

The American healthcare system is one of the most innovative in the world. But it’s also riddled with complex challenges, such as access to affordable medications, inefficiency and administrative burdens, and communication barriers between providers. There’s clearly a better way—and at Surescripts, we have a unique sightline into what that may be. In this series, host Melanie Marcus, Chief Marketing Officer of Surescripts, sits down with today’s most inspiring and innovative leaders in healt ...

Science Friction's latest series is: Cooked. We dig into food science pickles. Why are studies showing that ice cream could be good for you? Do we really need as many electrolytes as the internet says? And why are people feeling good on the carnivore diet? Nutrition and food scientist Dr Emma Beckett takes us through what the evidence says about foods like meat, ice cream and potatoes — and unpicks why nutrition studies can be so conflicting and confusing. All six episodes of Cooked are avai ...

In this episode of the St. Emlyn's podcast, Rick Body and Greg Yates delve into the concept of likelihood ratios, an advanced yet practical tool for diagnosing patients in the emergency department. Building on the previous episode about predictive values, they explain how likelihood ratios help compare the probability of test results between diseased and non-diseased patients. They provide examples, like evaluating chest pain and using the Smith Calculator for Anterior ST Elevation, to show how likelihood ratios can change clinical decision-making.
Rick and Greg also discuss Bayesian reasoning and how pretest and post-test probabilities are used in practice.
00:00 Introduction to the Podcast
00:34 Understanding Likelihood Ratios
02:05 Practical Example: Chest Pain Case
03:53 Calculating Likelihood Ratios
07:17 Applying Bayesian Reasoning
09:50 Recap and Conclusion
