Science Friday

As part of Science Friday’s 33rd anniversary show, we’re revisiting our listeners’ favorite stories, including this one from 2009.In the album “Here Comes Science,” the band They Might Be Giants tackled the scientific process, plasma physics, the role of blood in the body, and the importance of DNA, all in song. Band members John Linnell and John Flansburgh discuss the album and play some science tunes. The transcript for this segment is available at sciencefriday.com.  Subscribe to this podcast.

As part of Science Friday’s 33rd anniversary show, we’re revisiting our listeners’ favorite stories, including this one from 2022.66 million years ago, a massive asteroid hit what we know today as the Yucatán Peninsula of Mexico. Many people have a general idea of what happened next: The age of the dinosaurs was brought to a close, making room for mammals like us to thrive.But fewer people know what happened in the days, weeks, and years after impact. Increased research on fossils and geological remains from this time period have helped scientists paint a picture of this era. For large, non-avian dinosaurs like Triceratops and Tyrannosaurus rex, extinction was swift following the asteroid impact. But for creatures that were able to stay underwater and underground, their post-impact stories are more complicated.In 2022, Utah-based science writer Riley Black joined Ira to discuss her book The Last Days of the Dinosaurs.Transcripts for each segment will be available after the show airs on sciencefriday.com.

In 2022, the Nobel Prize in Chemistry went to Dr. Carolyn Bertozzi of Stanford University, Dr. Morten Meldal of the University of Copenhagen, and Dr. K. Barry Sharpless of the Scripps Research Institute “for the development of click chemistry and bioorthogonal chemistry.” In “click chemistry,” molecular building blocks snap together quickly and efficiently to let chemists build more complicated molecules. But bioorthogonal chemistry takes that work one step further, allowing the technique to be used within living organisms without damaging cells.“When someone is thinking outside the box, or in a very different way, we like to think of that as orthogonal thinking,” Bertozzi explained. “So biorthogonal means not interacting with biology. Totally separate from biology.” Her research began with an interest in developing ways to see specific sugar molecules on the surface of cells. But it has developed into an approach that can be used for advanced drug delivery in fields such as chemotherapy.As part of Science Friday’s 33rd anniversary show, we’re revisiting our listeners’ favorite stories, including this one. In 2022, Bertozzi joined Ira Flatow for a wide-ranging conversation about her research, chemistry education, her early music career, and the importance of diversity in the field of chemistry.Transcripts for each segment will be available after the show airs on sciencefriday.com.

In 2018, actor, author and science communicator Alan Alda spoke publicly about his diagnosis for Parkinson’s Disease. Alda, who is best known for his role in “M*A*S*H,” “The Aviator,” and “The West Wing,” shifted his interests to science communication in his later years. He’s written several books on the topic, and has an ongoing podcast, “Clear + Vivid.”As part of Science Friday’s 33rd anniversary show, we’re revisiting our listeners’ favorite stories, including this one. Alda came on Science Friday in 2018 to talk about his life since his Parkinson’s diagnosis, and how being an advocate for science changes his perspective on his condition. Transcripts for each segment will be available after the show airs on sciencefriday.com.
