Orcas vs Great White Sharks is more than a dramatic headline—it's a sign of how ocean ecosystems are shifting before our eyes. New drone footage shows orcas in the Gulf of California attacking and killing juvenile great white sharks in what scientists believe are nursery zones. The footage, captured in 2020 and 2022, reveals orcas flipping young sharks onto their backs, inducing tonic immobility, and surgically removing their livers—a precise and efficient hunting technique that may reshape predator-prey dynamics.

For years, scientists have known about great white shark nurseries, but what defines a "true nursery" has always been debated. These new observations raise deeper questions: Are orcas expanding their hunting grounds, or are juvenile sharks moving into new, warmer waters due to climate change? If orcas continue targeting young sharks, could this affect the recovery and stability of great white populations across the Pacific? In this episode, Andrew explores the science, the controversy, and what these interactions mean for the future of ocean conservation.

Ruthie's Table 4

Ruthie's Table 4

For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
