Hamish Johnston is joined by Oxford neutrino physicist Kirsty Duffy and Physics World's Matin Durrani to discuss the 2026 physics Nobel Prize awarded to Francis Halzen. They examine the IceCube observatory's contribution to detecting high-energy neutrinos from astrophysical sources and the broader history of Nobel-recognized neutrino research. The episode considers why these elusive particles have repeatedly transformed physics and how studying them opens a window onto the universe.

Alexandra Delbot discusses Young's double-slit experiment with physicists Christophe Salomon and Serge Haroche. They trace its role in establishing interference and examine how electron experiments, measurement and quantum theory changed the interpretation of the experiment and of wave-particle duality.

Physicist Daniel Akerib joins Sean Carroll to examine the search for weakly interacting massive particles and the challenges of directly detecting dark matter. They discuss a single unusual event in recent LUX-ZEPLIN data and why its low statistical significance warrants interest rather than a discovery claim. The conversation connects this result with Akerib’s experience in the Cryogenic Dark Matter Search, LUX and LUX-ZEPLIN experiments.

This episode explores transient searches, multiprobe cosmology and planetary nebulae through conversations with researchers at Jodrell Bank. Alex Reeves discusses his doctoral research, the computational methods used in multiprobe cosmology and his experience as a PhD student. Alec Csukai reflects on completing a doctorate in planetary-nebula research and the transition beyond graduate study. The presenters also discuss experiences of the August solar eclipse and share highlights from the Jodcast’s twentieth-birthday outreach activities at the National Astronomy Meeting. The episode combines current astrophysics with research-career perspectives and public engagement.

Hosted by Phoebe Ryder, Louisa Mason

Astrophysicist Benoît Famaey and theoretical physicist Francesca Calore discuss the evidence motivating dark matter and the challenges of identifying its nature. With Alexandra Delbot, they examine proposed particle candidates, possible detection signals and why a promising observation requires careful scrutiny before being treated as a discovery.

Francesca and Ilaria discuss taste-receptor research, mitochondrial biology and a reported ALS case study involving an antisense oligonucleotide treatment. Giuliana Galati interviews University of Padua physicist Francesco Recchia about nuclear phenomenology. The episode links these discussions to the underlying research papers and distinguishes a clinical case report from established treatment evidence.

Hosted by Francesca Cecilia Lauta, Ilaria Zanardi

Medical physicist Nick Zacharopoulos, chief executive of Aktina Medical, talks with Tami Freeman about developing radiation-oncology technologies and combining industry with academic research. He traces a career that began building radiotherapy components with his father, discusses product development at Aktina, and explains how persistence and a conversation with a colleague led him to a doctorate at McGill University.

This Nature Podcast explores how anonymized banking records can reveal patterns of financial abuse and inform support for victim-survivors. A second segment examines how opposing forces within Earth’s core can change the planet’s rotation and the length of a day. Research highlights cover Mercury’s contraction and cognitive resilience in predicting Alzheimer’s dementia.

Alexia Auffèves and Pascale Senellart-Mardon explain quantum energetics and the energy costs of quantum technologies. Alexandra Delbot asks how researchers can measure exchanges of energy, entropy and information, develop useful efficiency metrics, and incorporate energy constraints while quantum computers are still being designed.

Fraser Cain and Pamela L. Gay examine possible futures of the universe across vastly different timescales. Topics include the Milky Way and Andromeda, cosmic isolation as expansion continues, the fading microwave background, the end of star formation and the era of stellar remnants. They discuss uncertain processes such as proton decay, black-hole evaporation through Hawking radiation, entropy and heat death, alongside alternative outcomes if dark energy evolves. These are model-dependent projections. Pamela Gay is a senior scientist at the Planetary Science Institute. Published on 21 September 2026, the episode appears in the feed as The Beginning and End of Everything, Part 2. Its original duration is 37 minutes 7 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.

Hosted by Chris Smith

Theoretical physicist Jonathan Halliwell joins Steven Strogatz and Janna Levin to discuss how quantum decoherence helps explain the transition from wave-like quantum systems to the classical macroscopic world. The conversation covers quantum cosmology, decoherent histories, the measurement problem, macroscopic realism and why the quantum-to-classical transition does not require a conscious observer.

Hosted by Steven Strogatz, Janna Levin

Ethan Meitz and Jerry Wang discuss molecular simulation, heat transfer and the conversations that have shaped Meitz’s doctoral research. The episode connects computational methods with collaboration and mentoring, offering a practical view of research supported by the DOE Computational Science Graduate Fellowship.

Hosted by Sarah Webb

Leonardo and Andrea discuss internet censorship and recent work on Navier-Stokes equations involving AI, including the scientific significance and debate surrounding the results. The episode also contains Giuliano Greco's interview with Ivano La Rosa about a cyberpunk audio drama set in a future Genoa.

Hosted by Leonardo, Andrea

Fraser Cain and Pamela L. Gay explore what cosmology can establish about the universe’s earliest history and where knowledge remains limited. The discussion covers inflation, the separation of forces, the emergence of particles and nuclei, and density fluctuations that seed later structure. Recombination and the cosmic microwave background lead into the dark ages, the first stars and reionization, with observations including JWST helping test models of the early universe. Pamela Gay is a senior scientist at the Planetary Science Institute. This Astronomy Cast episode was published on 14 September 2026; its publisher feed labels it The Beginning and End of Everything, Part 1. The original duration is 39 minutes 27 seconds.

Hosted by Fraser Cain, Pamela L. Gay

Hamish Johnston speaks with iGii co-founder Marco Caffio about Gii, a porous three-dimensional carbon nanomaterial. They discuss how it retains useful electronic, structural and chemical properties associated with graphene while offering different manufacturing and integration options. Applications include chemical sensors, batteries and heaters. The conversation also covers the company’s origins and career advice for physicists entering materials technology.
