The United Nations Educational, Scientific and Cultural Organization ( UNESCO ) has declared 2025 the International Year of Quantum Science and Technology – or IYQ. UNESCO kicked-off IYQ on 4–5 February at a gala opening ceremony in Paris. Physics World ’s Matin Durrani was there, and he shares his highlights from the event in this episode of the Physics World Weekly podcast. No fewer than four physics Nobel laureates took part in the ceremony alongside representatives from governments and industry. While some speakers celebrated the current renaissance in quantum research and the burgeoning quantum-technology sector, others called on the international community to ensure that people in all nations benefit from a potential quantum revolution – not just people in wealthier countries. The dangers of promising too much from quantum computers and other technologies, was also discussed – as Durrani explains. This article forms part of Physics World ‘s contribution to the 2025 International Year of Quantum Science and Technology (IYQ), which aims to raise global awareness of quantum physics and its applications. Stayed tuned to Physics World and our international partners throughout the next 12 months for more coverage of the IYQ. Find out more on our quantum channel.…

This episode of the Physics World Weekly podcast looks at how climate and environmental change affect the efficiency of solar panels. Our guest is the climate scientist Sushovan Ghosh , who is lead author of paper that explores how aerosols, rising temperatures and other environmental factors will affect solar-energy output in India in the coming decades. Today, India ranks fifth amongst nations in terms of installed solar-energy capacity and boosting this capacity will be crucial for the country’s drive to reduce its greenhouse gas emissions by 45% by 2030 – when compared to 2005. While much of India is blessed with abundant sunshine, it is experiencing a persistent decline in incoming solar radiation that is associated with aerosol pollution. What is more, higher temperatures associated with climate change reduce the efficiency of solar cells – and their performance is also impacted in India by other climate-related phenomena. In this podcast, Ghosh explains how changes in the climate and environment affect the generation of solar energy and what can be done to mitigate these effects. Ghosh co-wrote the paper when at the Centre for Atmospheric Sciences at the Indian Institute of Technology Delhi and he is now at the Barcelona Supercomputing Center in Spain. His co-authors in Delhi were Dilip Ganguly, Sagnik Dey and Subhojit Ghoshal Chowdhury; and the paper is called, “Future photovoltaic potential in India: navigating the interplay between air pollution control and climate change mitigation ”. It appears in Environmental Research Letters , which is published by IOP Publishing – which also brings you Physics World .…

Heart failure is a serious condition that occurs when a damaged heart loses its ability to pump blood around the body. It affects as many as 100 million people worldwide and it is a progressive disease such that five years after a diagnosis, 50% of patients with heart failure will be dead. The UK-based company Ceryx Medical has created a new bioelectronic device called Cysoni, which is designed to adjust the pace of the heart as a patient breathes in and out. This mimics a normal physiological process called respiratory sinus arrhythmia, which can be absent in people with heart failure. The company has just began the first trial of Cysoni on human subjects. This podcast features the biomedical engineer Stuart Plant and the physicist Ashok Chauhan, who are Ceryx Medical’s CEO and senior scientist respectively. In a wide-ranging conversation with Physics World ’s Margaret Harris, they talk about how bioelectronics could be used treat heart failure and some other diseases. Chauhan and Plant also chat about challenges and rewards of developing medical technologies within a small company.…

As proclaimed by the United Nations, 2025 is the International Year of Quantum Science and Technology , or IYQ for short. This year was chosen because it marks the 100th anniversary of Werner Heisenberg’s development of matrix mechanics – the first consistent mathematical description of quantum physics. Our guest in this episode of the Physics World Weekly podcast is the Turkish quantum physicist Mete Atatüre , who heads up the Cavendish Laboratory at the UK’s University of Cambridge. In a conversation with Physics World ’s Katherine Skipper, Atatüre talks about hosting Quantour , the quantum light source that is IYQ’s version of the Olympic torch. He also talks about his group’s research on quantum sensors and quantum networks. There is much more about Heisenberg’s mathematical breakthrough in quantum physics here: “ Return to Helgoland: celebrating 100 years of quantum mechanics ”.

They lead the UK Metamaterials Network , which brings together people in academia, industry and governmental agencies to support and expand metamaterial R&D; nurture talent and skills; promote the adoption of metamaterials in the wider economy; and much more. According to the network, “A metamaterial is a 3D structure with a response or function due to the collective effect of meta-atom elements that is not possible to achieve conventionally with any individual constituent material”. In a wide-ranging conversation with Physics World ’s Matin Durrani, Hibbins and Dancer talk about exciting commercial applications of metamaterials including soundproof materials and lenses for mobile phones – and how they look forward to welcoming the thousandth member of the network sometime in 2025.…

Climate science and astronomy have much in common, and this has inspired the astrophysicist Travis Rector to call on astronomers to educate themselves, their students and the wider public about climate change. In this episode of the Physics World Weekly podcast, Rector explains why astronomers should listen to the concerns of the public when engaging about the science of global warming. And, he says the positive outlook of some of his students at the University of Alaska Anchorage makes him believe that a climate solution is possible. Rector says that some astronomers are reluctant to talk to the public about climate change because they have not mastered the intricacies of the science. Indeed, one aspect of atmospheric physics that has challenged scientists is the role that clouds play in global warming. My second guest this week is the science journalist Michael Allen, who has written a feature article for Physics World called “ Cloudy with a chance of warming: how physicists are studying the dynamical impact of clouds on climate change ”. He talks about climate feedback mechanisms that involve clouds and how aerosols affect clouds and the climate.

We are entering a second golden age of space travel – with human missions to the Moon and Mars planned for the near future. In this episode of the Physics World Weekly podcast we explore two very different challenges facing the next generation of cosmic explorers. First up, the radiation oncologist James Welsh chats with Physics World ’s Tami Freeman about his new ebook about the biological effects of space radiation on astronauts. They talk about the types and origins of space radiation and how they impact human health. Despite the real dangers, Welsh explains that the human body appears to be more resilient to radiation than are the microelectronics used on spacecraft. Based at Loyola Medicine in the US, Welsh explains why damage to computers, rather than the health of astronauts, could be the limiting factor for space exploration. Later in the episode I am in conversation with two physicists who have written a paper about how we could implement a universal time standard for the Moon. Based at the US’s National Institute of Standards and Technology (NIST), Biju Patla and Neil Ashby , explain how atomic clocks could be used to create a time system that would making coordinating lunar activities easier – and could operate as a GPS-like system to facilitate navigation. They also say that such a lunar system could be a prototype for a more ambitious system on Mars. Further reading Welsh’s ebook is called “ Space Radiation: Astrophysical origins, radiobiological effects and implications for space travellers ”. It is part of the IPEM–IOP Series in Physics and Engineering in Medicine and Biology . Ashby and Patla’s paper is called “ A Relativistic Framework to Estimate Clock Rates on the Moon ” and it appears in The Astronomical Journal .…
