Do science documentaries need a refresh? What if the goal wasn’t just teaching you something, but making you feel something? A new series from the BBC, airing on PBS, called “Human” tries to do just that. It tells the tale of our ancient family tree, embracing the complex and dramatic sides of the story. It asks: Who were the different species of humans that lived on this planet before us? What must it have been like to be in their shoes? And how did we become the only ones left standing? Ella Al-Shamahi, a paleoanthropologist and host of “Human,” tells SciFri Host Flora Lichtman about her vision for how to tell this story so that today’s humans lean in. Guest: Ella Al-Shamahi is a paleoanthropologist and the host of “Human” on BBC/PBS.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

TikTok Is Shaping How We Think About ADHD
TikTok and other social media sites are full of mental health content—often short, grabby, first-person videos detailing symptoms for conditions like ADHD and autism. But what does this mean for teens and young adults who spend hours a day scrolling?A new study published in PLOS One analyzes the 100 most viewed TikTok videos about ADHD to assess both how accurate they are and how young people respond to them. Researchers found that about half of the videos were inaccurate or missing key context, and that the more TikToks young adults watched, the less critical they were of the content.For some, watching social videos about mental health conditions led them to better understand themselves and eventually get a proper diagnosis and treatment. For others it made them consider if they have conditions they don’t meet the diagnostic criteria for.Host Flora Lichtman talks with the lead author of the ADHD TikTok study, Vasileia Karasavva, a PhD Student in clinical psychology at the University of British Columbia; and Dr. Jennifer Katzenstein, director of psychology, neuropsychology, and social work at Johns Hopkins All Children’s Hospital in St. Petersburg, Florida.Guests: Vasileia Karasavva is a PhD Student in Clinical Psychology at the University of British Columbia in Vancouver, Canada.Dr. Jennifer Katzenstein is Director of Psychology, Neuropsychology and Social work and Co-director of the Center for Behavioral Health at Johns Hopkins All Children’s Hospital in St. Petersburg, Florida.

Footage Shows How Narwhals Use Tusks To Hunt And Play
We’re taking a polar plunge into the science of sea unicorns, also known as narwhals!Narwhals are mysterious arctic whales with long, twirly tusks protruding from their foreheads, like a creature out of a fairy tale. And it turns out that we don’t know too much about them, partly because they live so far north in the remote Arctic.An international team of researchers used drones to observe narwhals in the wild and learned new things about their behavior, including how they use their tusks to hunt and play.Host Flora Lichtman gets on the horn with Dr. Gregory O’Corry-Crowe, research professor and biologist at Florida Atlantic University, who was an author on the new narwhal study, published last month in Frontiers in Marine Science.Guest: Dr. Greg O’Corry-Crowe is a research professor at Florida Atlantic University in Boca Raton, Florida.Transcripts for each episode are available at sciencefriday.com.

AI Was Supposed To Discover New Drugs. Where Are They?
AI is everywhere these days, and though there’s debate about how useful it is, one area where experts think it could be game-changing is scientific research. It promised to be particularly useful for speeding up drug discovery, an expensive and time-consuming process that can take decades. But so far, it hasn’t panned out.The few AI-designed drugs that have made it to clinical trials haven’t been approved, venture capital investment in these efforts has cratered in the last few years, and many startups have shut their doors. So why has it been so hard to make AI-designed drugs? What are the fundamental issues, and what does the future of this research look like?Joining Host Ira Flatow with some answers is Peter Coveney, who studies how chemistry discoveries can be sped up with algorithms and computers.Guest: Dr. Peter Coveney is a professor and director of the Centre for Computational Science at University College London.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

How Math Helps Us Map The World
It’s easy to take maps for granted. After all, most of us have a pretty good map in our pockets at all times, ready to show us how to get anywhere on the globe. But to make a map useful, you have to decide what to keep in and what to leave out—and, most importantly, which mathematical equations to use. Beyond navigating from point A to point B, math and maps come together for a wide variety of things, like working out the most efficient route to deliver packages, calculating the depth of the ocean floor, and more. Host Ira Flatow is joined by Paulina Rowińska, mathematician and author of Mapmatics: A Mathematician's Guide to Navigating the World, to go on a journey through the math at the heart of all kinds of maps. Guest: Dr. Paulina Rowińska is a mathematician, writer, science journalist and author of Mapmatics: A Mathematician's Guide to Navigating the World.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
