Alexandra Delbot reçoit Laurent Chauvaud et Frédéric Olivier pour explorer les coquilles de bivalves comme archives des milieux marins. La discussion explique comment les stries de croissance et leur composition chimique renseignent sur l’âge, la température, la salinité et les climats passés. Elle aborde aussi les pollutions, les perturbations acoustiques et les réponses biologiques des mollusques, envisagés comme indicateurs des changements de leur habitat.

Experiments using a giant wave machine test how salt marshes protect shorelines during extreme storms. The episode also explores evidence about Denisovan faces, orangutan mothers arranging play encounters, and the unequal effects of medieval lead exposure.

A global analysis suggests protected areas are more extensive than existing conservation accounts imply, while biodiversity remains under threat. A second research segment examines a large study associating brown fat with a broader range of health benefits. Research highlights consider Solar System stability and differences in brain aging among great apes.

John Platt discusses how Google’s applied-science team chooses problems where AI can make a useful contribution. Topics include satellite-based detection and prediction of aircraft contrails, evaluation of rerouting trials, limitations of physical simulation, and the role of AI agents in scientific modelling and data work. The conversation also examines overfitting, action incentives, gradient-free optimisation, SMO and support-vector machines, the physical constraints on scaling, and opportunities for robotics and manufacturing to support climate technology. It concludes with FireSat’s approach to detecting small wildfires from orbit and the practical issues of coverage, cost and false positives.

David Lodge discusses environmental DNA as a tool for detecting invasive species and the challenges of translating ecological evidence into policy. The conversation follows invasive-carp detection in river water, scrutiny in legal proceedings, long-term crayfish observations, and the respective roles of researchers and decision-makers.

Hosted by Marty Martin, John Drake

Andrew Glester explores how drones, robotics and machine learning support wildlife research and conservation. Blair Costelloe discusses the WildDrone and WildBotics networks and the Mara Elephant Project; Camille Rondeau Saint-Jean describes real-time animal monitoring; William Njoroge explains how Ol Pejeta Conservancy combines drones with established conservation methods. The episode considers population data, field constraints, regulation and collaboration across disciplines.

The Science Show examines mineral nodules formed around fossil shark teeth on the deep-sea floor and the ecological risks of exploiting them. The programme also considers plant responses to climate change, debates over introduced species, and the contributions and limitations of three influential scientists.

Hosted by Robyn Williams, Belinda Smith

Sarah Crespi and Katie Langin examine assisted migration: replanting forests after wildfire with trees suited to the warmer conditions expected in coming decades. Susana Monsó, associate professor in logic, history and philosophy of science at Spain’s National University of Distance Education, then discusses how philosophical analysis contributes to scientific work, from defining concepts to formulating research questions. Produced with help from Podigy; published 17 September 2026, with a running time of 37 minutes and 28 seconds.

Chris Smith and Rachael Ralph explore the mechanisms and forecasting of El Niño and its consequences for weather, livelihoods and health. Contributions from Aidan McGivern and Peter Gibbs explain the climate dynamics; Vicky Pryce discusses economic disruption; Rachel Tolhurst and Teresa Zakaria examine health vulnerabilities and preparedness. The episode connects climate science with the decisions facing public-health services and communities.

This Nature Podcast episode discusses telephone tutoring during school shutdowns and what changing world-map projections could mean for atlases. Research highlights cover synchronized optical clocks and greenhouse-gas emissions from pigs. The publisher provides the episode audio on Acast.

Nature's Benjamin Thompson and Maren Hunsberger discuss research recognised by the 2026 Ig Nobel prizes, including a soil-health experiment, and examine an intriguing signal from a xenon-based dark-matter experiment. Published on 4 September 2026, this episode connects environmental measurement with particle-physics news.

Nature reporters explain why record ocean temperatures associated with an intensifying El Niño could weaken marine carbon sinks. The episode also covers radiation protection for astronauts, thunder-based underground geology and experimental mitochondrial injections for vision loss.

Melissa and Jam trace the chemistry of refrigerants from early hazardous compounds to chlorofluorocarbons and their replacements. They explain why a substance that cools effectively can still create environmental problems, and discuss the tradeoffs among ozone protection, climate effects, flammability and regulation.

Hosted by Melissa, Jam

This bonus crossover from Inflection Point examines carbon-capture approaches, their history and the limits of their contribution to climate mitigation. The discussion includes ocean-based approaches and the chemical processes involved. It is the publisher’s syndicated episode in the Stereo Chemistry feed, rather than a separate new recording.

Nature journalists discuss a chemical route that converts PVC waste into motor lubricant and engineered yeast that produces a potential cancer drug.

Charlotte Gerischer and Melina von Wenczowski examine how detergents remove stains, how washing products developed and what their ingredients do. They discuss fragrance, surfactants and environmental consequences, with source references covering phosphate replacements, biodegradation and microplastic release during textile washing.

Hosted by Charlotte Gerischer, Melina von Wenczowski

Climate scientist Mathew Barlow explains why warming can intensify both drought and extreme rainfall. The episode follows water through a warmer atmosphere, connecting increased moisture capacity and evaporation with dry soils and stronger downpours. It distinguishes changes in average conditions from the most damaging extremes and discusses why infrastructure faces growing flood risks.

Hosted by Madison Goldberg

Polar scientist Sarah Das describes fieldwork on the Greenland and Antarctic ice sheets, from expedition logistics and ice-core drilling to transporting frozen samples to the laboratory. The conversation explains how ice cores preserve climate records and how repeated visits reveal retreating glacier margins and earlier melt seasons. It connects the practical work of glaciology with measured changes in polar landscapes.

Hosted by Madison Goldberg

Sarah Das explains how polar ice sheets, sea ice and mountain glaciers respond to climate warming. Drawing on decades of research in Antarctica and Greenland, the episode examines ice-sheet mass balance, glacier flow, satellite measurements and the consequences of ice loss for sea level and communities. It connects observations of rapidly changing frozen landscapes with their global effects.

Hosted by Madison Goldberg

Antoine Allanore explains why carbon dioxide emissions are so closely tied to the chemistry of conventional steel production. The episode connects steel’s widespread use in transport, infrastructure and buildings with its industrial climate footprint, and examines scientific and engineering approaches intended to reduce emissions from making the metal.
