Exploring Whales, Minds, and the Cosmos: A Naked Scientists Q&A

On this episode of The Naked Scientists, host James Tytko gathers a diverse panel to tackle listener questions that span whales, extremism, space, and maths. Tom Mustill shares insights from whale behavior and culture, Leor Zmigrod discusses cognitive neuroscience and susceptibility to radical ideas, Matt Bothwell outlines JWST discoveries and Euclid’s mission, and Ems Lord highlights maths in everyday life and the importance of number sense. The show weaves together biology, psychology, astronomy and education with engaging stories, including a dramatic whale encounter, space debris laser concepts, and a Mars mission miscalibration illustrating maths in practice.

• Whale culture and altruism in the ocean
• Cognitive rigidity and radicalization in the brain
• James Webb and Euclid top space science for 2023
• Number sense as a foundation for data literacy

Overview and guests

The Naked Scientists episode brings together host James Tytko and a panel of experts to answer questions from listeners. The conversation weaves through a spectrum of scientific topics, anchored by a human-interest anecdote from Tom Mustill about a humpback whale breaching onto his kayak in 2015. This sets the tone for impassioned discussions about animal behavior, brain function, and the communication of science across disciplines. The guests include Tom Mustill, author of How to Speak Whale; Leor Zmigrod, a Cambridge psychologist specializing in extremism and cognitive traits; Matt Bothwell, Cambridge public astronomer and James Webb Space Telescope enthusiast; and Ems Lord, director of Cambridge University's Maths Outreach Program, who frames maths as number sense and data literacy.

Whale behavior, culture and communication

Mustill recounts the 2015 encounter and explains why breaching is puzzling to scientists. He notes there is no consensus on the exact purpose of breaching, with theories ranging from social signaling to feeding and play. He emphasizes that humpback whales demonstrate culture through learned behaviors that are transmitted within populations, creating distinct foraging and social practices across populations. This challenges the view that certain animal behaviors are purely instinctual and highlights the growing field of animal culture and personality variation. The discussion transitions to how researchers study animal communication and the idea that whale songs and dialects can be culturally transmitted across individuals and generations.

Extremism, brain function and susceptibility to beliefs

Zmigrod’s segment frames extremism as a product of both brain traits and environmental influence. She describes cognitive rigidity as a neural and cognitive tendency to cling to initial impressions and resist change, which correlates with greater susceptibility to radical ideologies. The panel explores how brain signatures, such as rigidity, interact with exposure to information and propaganda, and how researchers differentiate vulnerability from actual involvement. The discussion also touches on public policy debates like the Prevent program, highlighting the tension between intervention and civil liberties, and stressing the importance of early support for individuals at risk before exposure to harmful ideologies.

Astronomy, space missions and discoveries

Matt Bothwell shares updates on the James Webb Space Telescope, noting the mission’s impressive performance and extended operational lifespan due to precise fuel management. He discusses Euclid, a European Space Agency mission designed to map dark energy and dark matter by tracking the expansion history of the universe. The conversation clarifies the cosmic acceleration, the mystery of dark energy, and how large-scale surveys help constrain models of the universe. The panel connects these cosmic questions to public engagement and the excitement of new data and observations that reshape our understanding of the cosmos.

Mathematics, numeracy and education

Ems Lord discusses mathematics education and the push to make maths a core data-literacy skill for the general population. She distinguishes numeracy from mathematics and argues for curricula that foster data interpretation and critical thinking, rather than solely focusing on equation solving. Lord shares the idea of exploring mathematical missteps and the potential value of error analysis in real-world projects. The conversation also covers a memorable error in a Mars mission due to unit conversions between Imperial and metric systems, illustrating how number sense and careful verification can prevent costly mistakes in high-stakes engineering.

Brain science, perception, and misinformation

The panel examines how information can alter the brain and vice versa. They discuss how the brain’s plasticity changes with age, the bidirectional influence of information exposure and belief formation, and how hallucinations reflect brain networks that process both real and imagined sensory inputs. The discussion emphasizes the challenges of communicating complex science to the public and the importance of visual and narrative tools to convey difficult concepts clearly.

Quiz segment and show closing

The episode features a lighthearted quiz in which teams answer questions on X-ray history, the periodic table, and brain numbers. The quiz underscores the program’s blend of serious science with accessible entertainment. The hosts reflect on the excitement of exploration, the excitement of not knowing everything, and the value of curiosity in engaging diverse audiences with science.

Takeaways

The podcast demonstrates how science intersects with culture, policy, education, and public understanding. It showcases interdisciplinary dialogue, blending biology, psychology, astronomy, and mathematics to illuminate how questions are asked, how answers are formed, and how science can be made accessible and engaging to a broad audience.
