Margaret Harris, a knowledgeable colleague at Physics World, discusses the recent discovery of auroras on Mars by NASA's Perseverance Rover, shedding light on planetary atmospheres. She also contemplates the ultimate fate of the universe and the future of white dwarf stars. Matin Durrani shares intriguing insights about Werner Heisenberg's pivotal retreat to Helgoland in 1925, where he developed crucial quantum mechanics principles. The conversation rounds off with innovative uses of neutron science for authenticating antique coins, revealing fascinating intersections between physics and history.

James Wootton, Chief Scientific Officer at Moth Quantum, shares his insights on merging quantum computing with creative fields. He discusses how artists, musicians, and game designers can leverage specialized quantum software to revolutionize their work. Wootton emphasizes the unique advantages of quantum systems in procedural generation for games, enhancing creativity through probabilities. He also highlights the vital role of storytelling and public engagement in making quantum concepts accessible, demonstrating the fusion of technology and artistry.

Nadya Mason, Dean of the Pritzker School of Molecular Engineering, dives into how molecular engineering is revolutionizing quantum computing, sustainability, and biomedical technologies. Jeffrey Spangenberger, leader of the Materials Recycling Group at Argonne National Laboratory, discusses the intricacies of battery recycling and the innovative methods being developed for a more sustainable future. Together, they explore the potential of cutting-edge science to create a circular economy and advance technologies that address global challenges.

This episode of the Physics World Weekly podcast features the Nobel laureate Ferenc Krausz. He is director of the Max-Planck Institute of Quantum Optics and a professor at LMU Munich, both in Germany, and CEO and scientific director of the Center for Molecular Fingerprinting in Budapest, Hungary. In a conversation with Physics World’s Tami Freeman Krausz talks about his research into using ultrashort-pulsed laser technology to develop a diagnostic tool for early disease detection. He also discusses his collaboration with Semmelweis University to establish the John von Neumann Institute for Data Science, and describes the Science4People initiative, a charity that he and his colleagues founded to provide education for children who have been displaced by the war in Ukraine. On 13–14 May, The Economist is hosting Commercialising Quantum Global 2025 in London. The event is supported by the Institute of Physics – which brings you Physics World.

This episode of the Physics World Weekly podcast features the materials scientist Paul Meredith, who is director of the Centre for Integrative Semiconductor Materials (CISM) at the UK’s Swansea University. In a conversation with Physics World’s Matin Durrani, Meredith talks about the importance of semiconductors in a hi-tech economy and why it is crucial for the UK to have a homegrown semiconductor industry. Founded in 2020, CISM moved into a new, state-of-the-art £50m building in 2023 and is now in its first full year of operation. Meredith explains how technological innovation and skills training at CSIM is supporting chipmakers in the M4 hi-tech corridor, which begins in Swansea in South Wales and stretches eastward to London.

This podcast features Alonso Gutierrez, who is chief of medical physics at the Miami Cancer Institute in the US. In a wide-ranging conversation with Physics World’s Tami Freeman, Gutierrez talks about his experience using Elekta’s Leksell Gamma Knife for radiosurgery in a busy radiotherapy department.
