It is Peer Review Week and celebrations are well under way at IOP Publishing (IOPP), which brings you the Physics World Weekly podcast.

Reviewer feedback to authors plays a crucial role in the peer-review process, boosting the quality of published papers to the benefit of authors and the wider scientific community. But sometimes authors receive very unhelpful or outright rude feedback about their work. These inappropriate comments can shake the confidence of early career researchers, and even dissuade them from pursuing careers in science.

Our guest in this episode is Laura Feetham-Walker, who is reviewer engagement manager at IOPP. She explains how the publisher is raising awareness of the importance of constructive and respectful peer review feedback and how innovations can help to create a positive peer review culture.

As part of the campaign, IOPP asked some leading physicists to recount the worst reviewer comments that they have received – and Feetham-Walker shares some real shockers in the podcast.

IOPP has created a video called “Unprofessional peer reviews can harm science” in which leading scientists share inappropriate reviews that they have received.

The publisher also offers a  Peer Review Excellence  training and certification programme, which equips early-career researchers in the physical sciences with the skills to provide constructive feedback.

This episode of the Physics World Weekly podcast features two medical physicists working at the heart of the UK’s National Health Service (NHS). They are Mark Knight, who is chief healthcare scientist at the NHS Kent and Medway Integrated Care Board, and Fiammetta Fedele, who is head of non-ionizing radiation at Guy’s and St Thomas NHS Foundation Trust in London.

They explain how medical physicists keep people safe during healthcare procedures – while innovating new technologies and treatments. They also discuss the role that artificial intelligence could play in medical physics and take a look forward to the future of healthcare.

This episode is supported by RaySearch Laboratories.

In this episode of the Physics World Weekly podcast we explore two related areas of physics, statistical physics and thermodynamics.

First up we have two leading lights in statistical physics who explain how researchers in the field are studying phenomena as diverse as active matter and artificial intelligence.

They are Leticia Cugliandolo who is at Sorbonne University in Paris and Marc Mézard at Bocconi University in Italy.

Cugliandolo is also chief scientific director of Journal of Statistical Mechanics, Theory, and Experiment (JSTAT) and Mézard has just stepped down from that role. They both talk about how the journal and statistical physics have evolved over the past two decades and what the future could bring.

The second segment of this episode explores how intense storms can affect your cup of tea. Our guests are the meteorologists Caleb Miller and Giles Harrison, who measured the boiling point of water as storm Ciarán passed through the University of Reading in 2023. They explain the thermodynamics of what they found, and how the storm could have affected the quality of the millions of cups of tea brewed that day.

This episode of the Physics World Weekly podcast looks at quantum computing from two different perspectives.

Our first guest is Elena Blokhina, who is chief scientific officer at Equal1 – an award-winning company that is developing hybrid quantum–classical computing chips. She explains why Equal1 is using quantum dots as qubits in its silicon-based quantum processor unit.

Next up is Brandon Grinkemeyer, who is a PhD student at Harvard University working in several cutting-edge areas of quantum research. He is a member of Misha Lukin’s research group, which is active in the fields of quantum optics and atomic physics and is at the forefront of developing  quantum processors that use arrays of trapped atoms as qubits.

On 15 August 1977 the Big Ear radio telescope in the US was scanning the skies in a search for signs of intelligent extraterrestrial life. Suddenly, it detected a strong, narrow bandwidth signal that lasted a little longer than one minute – as expected if Big Ear’s field of vision swept across a steady source of radio waves. That source, however, had vanished 24 hours later when the Ohio-based telescope looked at the same patch of sky.

This was the sort of technosignature that searches for extraterrestrial intelligence (SETI) were seeking. Indeed, one scientist wrote the word “Wow!” next to the signal on a paper print-out of the Big Ear data.

Ever since, the origins of the Wow! signal have been debated – and now, a trio of scientists have an astrophysical explanation that does not involve intelligent extraterrestrials. One of them, Abel Méndez, is our guest in this episode of the Physics World Weekly podcast.

Méndez is an astrobiologist at the University of Puerto Rico at Arecibo and he explains how observations made at the Arecibo Telescope have contributed to the trio’s research.

This episode of the Physics World Weekly podcast explores how physics can be used as a force for good – helping society address important challenges such as climate change, sustainable development, and improving health.

Our guest is the Swiss physicist Christophe Rossel, who is a former president of the European Physical Society (EPS) and an emeritus scientist at IBM Research in Zurich.

Rossel is a co-editor and co-author of the book EPS Grand Challenges, which looks at how science and physics can help drive positive change in society and raise standards of living worldwide as we approach the middle of the century. The huge tome weighs in at 829 pages, was written by 115 physicists and honed by 13 co-editors.

Rossel talks to Physics World’s Matin Durrani about the intersection of science and society and what physicists can do to make the world a better place.

Margot Taylor – director of functional neuroimaging at Toronto’s Hospital for Sick Children – is our first guest in this podcast. She explains how she uses optically-pumped magnetometers (OPMs) to do magnetoencephalography (MEG) studies of brain development in children.

An OPM uses quantum spins within an atomic gas to detect the tiny magnetic fields produced by the brain. Unlike other sensors used for MEG, which must be kept at cryogenic temperatures, OPMs can be deployed at room temperature in a simple helmet that puts the sensors very close to the scalp.

The OPM-MEG helmets are made by Cerca Magnetics and the UK-based company’s managing director joins the conversation to explain how the technology works. David Woolger also talks about the success the company has enjoyed since its inception in 2020.

Our final guest in this podcast is Stuart Nicol, who is chief investment officer at Quantum Exponential – a UK-based company that invests in quantum start-ups. He gives his perspective on the medical sector, talks about a company called Siloton that is making a crucial eye-imaging technology more accessible.

This podcast explores the extraordinary life of the Pakistani physicist Abdus Salam, who is celebrated for his ground-breaking theoretical work and for his championing of physics and physicists in developing countries.

In 1964, he founded the Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste, Italy – which supports research excellence worldwide with a focus on physicists in the developing world. In 1979 Salam shared the Nobel Prize for Physics for his work on the unification of the weak and electromagnetic interactions.

Salam spent most of his career at Imperial College London and the university is gearing up to celebrate the centenary of his birth in January 2026. In this episode of the Physics World Weekly podcast, Imperial physicists Claudia de Rham and Ian Walmsley look back on the extraordinary life of Salam – who died in 1996. They also talk about the celebrations at Imperial College.

This episode of the Physics World Weekly podcast features an interview with Margaret Arakawa. She is chief marketing officer at IonQ – which makes trapped ion quantum computers. An economist by training, Arakawa spent 25 years in the (classical) computing industry before joining IonQ. We chat about why she made the move to the quantum sector and about the wide range of opportunities for non-physicists in the quantum-technology industry.

Arakawa also talks about the challenges of marketing quantum technology to customers who might not understand the underlying physics and explains why the quantum industry must avoid hype.

Our second guest is Nat Mendelsohn, who represents the English Midlands on the Institute of Physics’ Student Community Panel. He talks to Physics World’s Katherine Skipper about the student experience – what is good and what can be improved. He also explains how the COVID-19 pandemic continues to have a profound impact on higher education.

Finally, I chat with Skipper about her trip to Prague for the 42nd International Conference on High Energy Physics. High on the agenda was what collider of the future will be the successor of the Large Hadron Collider.

Our first guest in this episode of the Physics World Weekly podcast is Derek Sutherland, who is head of FuZE-Q physics at the US-based company Zap Energy. He explains how the US-based firm is designing a fusion system that does not rely on magnets, cryogenics or high-powered lasers to generate energy. We also chat about the small-scale fusion industry in general, and about career opportunities for physicists in the sector.

This episode also features an interview with theoretical physicist and author Claudia de Rham. She talks to Physics World’s Matin Durrani about her new popular-science book The Beauty of Falling.
