Spaghetti Science And Mouth Taping Myths

Most pasta is made from just two ingredients—flour and water. For decades this humble food has prompted physicists around the world to try to understand its mysterious properties and answer questions like: Why does a stick of spaghetti break into three pieces and not cleanly into two? And why is cacio e pepe so hard to perfect? The answers reveal more about the building blocks of the universe than you might expect. Host Ira Flatow talks with Joseph Howlett, math writer at Quanta Magazine, and author of a recent story for the BBC about spaghetti science. And, if you frequent the wellness world on social media, you may have seen a trend popular with influencers: using adhesive tape to seal one’s mouth shut while sleeping. This is intended to help the sleeper breathe through their nose all night, which people claim has a slew of benefits including improved quality of sleep, reduced sleep apnea, a more defined jawline, and a brightened complexion. But should you add mouth taping to your nighttime routine? According to Dr. Linda Lee, physician and surgeon at Massachusetts Eye and Ear in Boston, you should be evaluated by a professional first. Dr. Lee joins Host Flora Lichtman to talk about the right way to start nose breathing, what the scientific literature says (and doesn’t say) about mouth taping, and how social media is changing the information patients seek from their physicians.

The Leap: Everything Else Is Boring

In both her life and her work, researcher Karmella Haynes has never followed the pack. Karmella explains why she created her own area of research at the intersection of synthetic biology and epigenetics. Emory colleague David Katz weighs in on the challenges Karmella faces in pioneering a new research field. Plus Karmella’s sister Sherrone Wallace fills us in on their family life, and how their father raised them to inhabit spaces that weren’t always welcoming. Karmella has been recognized by the Hypothesis Fund as a Scout for her bold science and enabling others to pursue their big ideas. “The Leap” is a 10-episode audio series that profiles scientists willing to take big risks to push the boundaries of discovery. It premieres on Science Friday’s podcast feed every Monday until July 21. “The Leap” is a production of the Hypothesis Fund, brought to you in partnership with Science Friday.

What Does It Mean To Have A Chatbot Companion?

AI is not just for automating tasks or coming up with new recipe ideas. Increasingly, people are turning to AI chatbots for companionship. Roughly half a billion people worldwide have downloaded chatbots designed specifically to provide users with emotional and social support. And while these human-chatbot relationships might ease loneliness or simply be fun to have, these digital friends can also cause real harm by encouraging dangerous or inappropriate behavior—especially in children or teens. To explore the emerging world of AI companion chatbots, Host Flora Lichtman is joined by freelance science reporter David Adam, who recently wrote about the effect of AI companions on mental health for Nature magazine; and Rose Guingrich, a psychology researcher studying interactions between humans and AI at Princeton University. Guests: David Adam is a freelance science reporter based in London. Rose Guingrich is a researcher in the department of psychology at Princeton University.

Engaging stories that feed my curiosity, from minor tidbits I didn't even know I wanted to know about, to major stories of discovery and policy set in a broad clarifying context. Engaging energetic hosts.
So worth it!

Curiosity is cool

I love science Friday and it is why I recently vowed to provide more support for the show. It not only reminds us of the importance of science in a time of skepticism, but it does it in such a fun, accessible way while also bringing awe and wonder into my everyday life. I have really appreciated all of the inspiring stories in Flora’s recent “leap” series. Keep up the great work!
Science is true whether or not it aligns with your politics

…to evoke NdGT. The Science Friday team does a great job of presenting the stories behind the science, and the new format of daily releases gives you the choice between listening to the whole show, or each chunk per day.
Great Show

I love both Ira and Flora. I appreciate the variety of scientific fields explored. The show walks the fine line between explaining scientific concepts in detail, but still making them comprehensible for the general public.
