From saving the planet to understanding ourselves, this podcast sees experts discuss the major topics of our times. Hosted by IFLScience’s Dr Alfredo Carpineti, Rachael Funnell, Dr Russell Moul, Laura Simmons, and Eleanor Higgs.Themes and summary (AI-generated based on podcaster-provided show and episode descriptions):
➤ expert-led big questions across science • psychology of belief, fear, perception (magic, paranormal) • climate change, Anthropocene, glaciers, biodiversity loss/extinction • space/astronomy (black holes, space weather, solar flares, space junk) • biology, evolution, consciousness, health tech (vaccines, antibiotics, longevity, de-extinction)This podcast explores wide-ranging “big questions” through conversations with scientists, researchers, and other subject-matter experts. Across the episodes, the show moves between core themes in physics and cosmology—such as the nature of time, black holes, antimatter, dark matter and dark energy, the limits of computation, quantum technology, nuclear fusion, and how the Solar System and universe might end—and questions about how these phenomena affect life on Earth, from space weather and solar flares to the growing problem of orbital debris.
A major thread focuses on environmental change and humanity’s planetary impact. Discussions consider climate-driven shifts in glaciers and polar ecosystems, debates around whether the Anthropocene is a formal geological epoch, and how today’s waste could leave a long-term signature as “technofossils.” Biodiversity loss and extinction risk recur frequently, with attention to how scientists determine when a species is truly extinct, whether we’re in a sixth mass extinction, and what tools—ranging from genetics to novel conservation strategies—might help prevent or even reverse losses, including attempts at “de-extinction.”
The show also examines biology, health, and the mind: evolution and human origins, animal intelligence and welfare, aging and lifespan extension, infectious disease prevention, antibiotic discovery, nutrition and disease, and the effects of drugs and alcohol on the brain. Complementing these are episodes on psychology and culture, including why people report paranormal experiences, how fear and belief work, how competitive play shapes behavior, how imagination and consciousness are studied, and how the internet accelerates language change. Occasional investigations use topics like magic or cryptozoology to illuminate perception, attention, misinformation, and scientific skepticism.
