About this episode

What was your favorite science story of 2023? Was it the rise of orca-involved boat sinkings? Or maybe the successful landing of India’s Chandrayaan-3 mission at the moon’s south pole

This week, it’s the second and final part of our annual event about the best science stories of the year, with a roundup of some of the good news, animal news and all-around most important stories of 2023. Like how researchers discovered the high-tech material called graphene can also occur naturally…and did, deep in the Earth, 3 billion years ago. Or how the World Health Organization ended the global health emergency declaration for covid-19.

Plus, wonders from the animal kingdom: innovative bird nests made of anti-bird spikescooperation between dolphins and fishermen in Brazil and the incredible clogging power of hagfish slime.

Hosts Timothy Revell and Christie Taylor discuss all of this and more with guests Clare Wilson, Sam Wong, and Leah Crane. To read more about these stories, visit
