Ethan Secor discusses additive manufacturing methods for printing electronic circuits onto complex three-dimensional surfaces. The conversation connects material choices, printing techniques and the design of electronics that conform to shaped objects, highlighting the research behind customized functional surfaces.

This Briefing Chat examines a tattoo ink that becomes visible under ultraviolet light and then fades, before discussing whether epigenetic changes and jumping genes help explain why larger dogs age more quickly.

Jonathan Webb and ABC science reporter Ellen Phiddian examine textile absorbency and why an older tea towel can sometimes dry better than a new one. The discussion connects everyday fabric performance with the behaviour of fibres and considers when a worn towel should be replaced.

Taylor Sparks and Andrew Falkowski speak with University of Arizona researcher Marat Latypov about aluminium's transition from a scarce, expensive metal to a widely used engineering material. They discuss extraction, corrosion resistance, precipitation hardening, electrical wiring and automotive applications, and the technical difficulties of recycling mixed scrap.

Hosted by Taylor Sparks, Andrew Falkowski

Benjamin Thompson and Shamini Bundell discuss two scientific stories from the Nature Briefing. The first concerns a technique for detecting lead that may help researchers read damaged Roman scrolls from Herculaneum without unrolling the fragile, charred material. The second examines a biodegradable, paper-inspired edible battery and its potential use in medical devices inside the body. The publisher’s episode page and official podcast feed both identify this 25 September 2026 episode; the discussion lasts 11 minutes 32 seconds.

This edition of The Science Show covers extinct big cats and early humans, the material properties behind durable Roman concrete, the history of technological disruption by space weather, and methane-consuming microorganisms living in tree bark.

Hosted by Robyn Williams, Belinda Smith

Chris Smith presents a science-news episode examining how artificial intelligence could be misused to develop biological weapons and how researchers and regulators are responding. The programme also covers long-lasting genetic scars after childhood chemotherapy, ultra-strong ice as a possible construction material, and methods for tracking weather patterns on distant planets.

C&EN journalists examine the chemistry behind sustaining human activity beyond Earth. Topics include obtaining useful resources, designing materials and understanding the practical constraints of living and working in space. The episode connects chemical research with planetary resources and engineering.

Hosted by Craig Bettenhausen

The Chemistry World team examines research on CAR-T immunotherapy for bladder tumours, including results in mice and the challenges of treating solid cancers. A second discussion considers how incorrectly assigned spectral features may have affected interpretations of defects in carbon materials.

Hosted by Mariana Kneppers

Mariana Kneppers, Mason Wakley and Jamie Durrani discuss changes affecting UK science policy and investigate the chemistry of deteriorating concrete in Ireland. The materials discussion examines the roles of mica, iron-sulfide minerals, oxidation and subsequent chemical reactions in structural damage.

NASA aerospace engineer Nate Olson joins Taylor Sparks and Andrew Falkowski to discuss the materials and engineering behind spacecraft thermal protection. Topics include blunt-body designs, Apollo’s ablative heat shield, the Artemis I heat-shield anomaly and future protection systems. The scientific discussion is part of the Materialism materials-science series.

Hosted by Taylor Sparks, Andrew Falkowski

Mariana Kneppers, Frankie Macpherson and Phillip Broadwith discuss allegations about manipulated antibody-validation images in Thermo Fisher Scientific's catalogue and the questions they raise for research integrity. They also examine the technical and commercial difficulties facing chemical recycling of plastics.

Hosted by Mariana Kneppers

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

Mariana Kneppers, Mason Wakley and Jamie Durrani revisit the Seveso chemical disaster and its lasting health and regulatory consequences. They also discuss membrane materials designed to separate hydrocarbons with less energy than conventional refinery processes, connecting materials research to industrial efficiency.
