Curiosity Daily Podcast: The Science of Swearing and What it Says About Our Values

Let’s say one day astronomers announce that our worst nightmare has come true: a large object is headed towards the Earth with a significant chance of impact. What do we do?

See how these apex predators actually think. Will they completely transform our understanding of their intelligence?

Take a bite out of our 38th annual Shark Week event, starting July 26, 2026! Here's everything we have coming up, only on Discovery.

In our annual New Year’s family tradition of struggling to stay awake until midnight, we decided to watch “Don’t Look Up,” the Adam McKay satire starring Leonardo DiCaprio, Jennifer Lawrence, and other fabulously good-looking people.

In this season’s final episode, Luke welcomes Emmy-winning filmmaker and conservationist Shawn Heinrichs to discuss the state of sharks in the ocean. They go over how both legal and illegal fishing operations are decimating the ocean’s wildlife, what it’s like to have a hit put out on you for exposing criminal enterprises to the world, and whether or not NOAA’s data on “sustainable” fishing can really be trusted.

Shark Week’s Luke Tipple tackles the question “How can I work with sharks?” alongside two experts in the field – and their answers are not always the obvious ones. Luke is joined first by Kelly Link, Associate Curator of the Georgia Aquarium who talks about what it’s like to be an aquarist, how it differs from field work, and how to get yourself noticed. The second guest is Dr. Neil Hammerschlag who goes into detail on what it takes to become a prominent scientist, and what other paths you can take if a PhD isn’t for you. And at the end, researcher Sierra stops by to tell us about the world’s smallest shark.

Host Luke Tipple welcomes two guests to discuss how researchers can kill sharks in the name of science – and whether they need to at all. The first is Dr. Neil Hammerschlag, shark researcher and founder of Atlantic Shark Expeditions, and an expert on data-gathering in the field. He’s followed by explorer Fred Buyle, a world-record-breaking freediver whose innovative methods of shark tagging are explored. Plus, our researcher Sierra tells us about how a 50-year study changed our understanding of tiger sharks – and much of the work wasn’t even done by scientists.

Luke Tipple invites “The Lost Shark Guy,” Dr. Dave Ebert, who is personally responsible for finding dozens of shark species that were either previously unknown to science or thought to be extinct. He and Luke discuss why shark populations are a direct indicator of how healthy the ocean is, how to find undiscovered sharks, and why diversity in sharks is essential for marine life.

Pop superstar Kesha joins Shark Week’s Luke Tipple on the podcast to discuss her love of sharks, how her music funds her addiction to diving, and how you can find inner peace while under the water. And at the end, our researcher Sierra drops in to tell us that some sharks have teeth in their eyes.

Shark Week’s Luke Tipple is joined by longtime filmmaker and Emmy-award-winner Andy Casagrande. He’s filmed and appeared in dozens of shark documentaries, and might just be the most prolific shark cinematographer in history. He talks with Luke about his career, the contentious term “shark porn,” and the future of the industry. And at the end, our researcher Sierra talks about the unprecedented ways that sharks are currently endangered.
