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 science discussions • climate change, Anthropocene, glaciers, extinction, conservation • space and cosmology: black holes, universe origins/ending, solar flares, space weather, junk • biology, evolution, sentience, aging • tech, computing, language • psychology of belief, paranormal, magic, misinformation • health, vaccines, diet, drugsThis podcast explores wide-ranging “big questions” in science by pairing journalists and scientist-hosts with researchers, authors, and other specialists. Across the episodes, conversations move between fundamental mysteries of the universe and practical challenges shaping modern life, with an emphasis on how evidence is gathered and how scientific debates unfold.
A recurring thread is Earth’s changing environment and humanity’s role in it. Topics include climate-driven impacts on glaciers, ice cores as records of past and future change, biodiversity loss and extinction risk, conservation interventions that rely on genetics and reproductive technologies, and how human activity may be preserved in the geological record through “technofossils.” Related discussions look at potential technological responses such as alternative fuels and new approaches to food production.
Health and biology also feature prominently, from vaccinology and antibiotic discovery to the biology of aging, diet and disease, animal cognition and welfare, and evolutionary questions about humans and other species. Several episodes examine how scientific ideas can be shaped by assumptions and bias, and how new evidence revises what we think we know.
On the physics and space side, the show tackles black holes, cosmology, antimatter, the composition and fate of the universe, the long-term future of the solar system, and space hazards like solar storms, space weather, and orbital debris. Computing and technology topics include the limits of classical computing and the promise and hurdles of quantum machines.
Interwoven with these are episodes on perception, belief, and misinformation—using subjects like magic, paranormal experiences, and cryptozoology as entry points into psychology, attention, and why people accept extraordinary claims.
