Trouble on the Horizon for UK-based researchers

Researchers in the United Kingdom are facing an uncertain future, due to a political spat about the UK’s participation in Horizon Europe – Europe’s flagship research funding programme. Following Brexit, the UK was set to become an official associate within the scheme, which brings funding and leadership opportunities within European projects. This is now threatened by a political disagreement over trading arrangements in Northern Ireland. In this episode of the Physics World Stories podcast, sc...

The science-fiction legacy of Satyajit Ray

A small alien creature crash lands on Earth before striking up a rapport with a boy. Sound familiar? Two decades before ET was released, Indian director Satyajit Ray wrote a script for a film that would be called The Alien, which bears striking similarities with Steven Spielberg’s Hollywood blockbuster. The movie was never made. Ray was ahead of his time in many ways. Although not primarily remembered for his science fiction, the Bengali polymath was frequently inspired by a scientific way of th...

The Higgs boson discovery revisited

Everyone knew something big was coming. Students had camped outside CERN’s designated seminar hall overnight in the hope of grabbing one of the few unreserved seats. Finally, on the morning of 4 July 2012, the suspense was ended. Spokespeople for the large hadron collider’s two general purpose experiments, ATLAS and CMS, confirmed the rumours: both experimental teams had detected a “Higgs-like particle” and the masses were very similar. In the July episode of the Physics World Stories podcast, ...

Fixing our bodies with glass

From windows and bottles, to optical fibres and solar cells, glass is an incredibly versatile material that underpins many technologies. In the June episode of the Physics World Stories podcast, Andrew Glester explores a lesser known application of glass – bioglass in healthcare. First you will hear from Julian Jones at Imperial College London, who explains how glass putty can help to heal broken bones by stimulating tissue growth. Jones has previously worked with the inventor of bioglass, Larr...

Cutting the carbon footprint of supercomputing in scientific research

Science benefits enormously from supercomputing, which enables researchers to process vast amounts of data and conduct complex simulations. But these machines can be notorious energy guzzlers, with the largest supercomputers consuming as much power as a small city. In this episode of the Physics World Stories podcast, scientists discuss how individuals can reduce the environmental impact of supercomputing without compromising research goals. Simon Portegies Zwart, an astrophysicist at Leiden Un...

JET’s record result and the quest for fusion energy

One of longest-running physics jokes is that, despite numerous promising breakthroughs, practical nuclear fusion will forever be 30 years away. Earlier this year, there was an exciting result in the UK that suggests that – sooner or later – fusion scientists will have the last laugh. The Joint European Torus (JET) nuclear-fusion experiment based in Oxfordshire, UK, more than doubled the amount of sustained fusion energy produced in a single “shot” – smashing a previous record that JET has held s...

Music from our material world

From Vivaldi’s “The Four Seasons” concertos to the Beatles’ “Blackbird” – musicians have always been inspired by nature. Many artists have even incorporated the sounds of nature into their songs. Now, researchers at the Massachusetts Institute of Technology (MIT) are taking a more fundamental approach, exploring the music of the building blocks of life and how they interact in harmonious ways. In this episode of the Physics World Stories podcast, host Andrew Glester speaks with Markus Buehler, ...

Sharing is caring: open hardware has global impact

The open hardware movement advocates the sharing of designs for material objects. For the global science community it means people can access instructions to 3D print increasingly sophisticated tools. Just as importantly, the movement is decentralizing knowledge and giving users the ability to customize scientific equipment then repair it when things go wrong. In the latest episode of Physics World Stories, Andrew Glester meets researchers at the University of Bath who are part of the open scie...

Deflecting asteroids and exploring a metal world

You could be forgiven for thinking the themes in this month’s episode of Physics World Stories have been stolen from Hollywood. Podcast host Andrew Glester profiles two upcoming NASA missions to asteroids: one that will explore an all-metal world, and the other will deliberately smash into a near-Earth asteroid. Glester’s first guest is Jim Bell from Arizona State University who is involved in the mission to the asteroid Psyche, which launches in 2022 and arrives in 2026. Located in the asteroi...

Helgoland and the captivating origins of quantum theory

In June 1925 Werner Heisenberg retreated to Helgoland in the North Sea, a treeless island offering the 23-year-old German physicist a space to think, along with some respite from the extreme hay fever he was suffering. On that remote outpost, Heisenberg had an idea that would revolutionize physics and bring profound implications for philosophy and technology. This was an event that would kickstart quantum mechanics. Carlo Rovelli. (Courtesy: Christopher Wahl) Helgoland is the title of the lates...

The bots are not as fair-minded as they seem

Artificial intelligence (AI) technologies are designed to replicate human capabilities, and in some cases improve upon them. Lifelike robots are physical examples of AI technology, but it is the digital AI systems that already have a ubiquitous influence on our daily lives – from facial recognition software to decision-making tools used by banks, recruiters and the police. Too often, these systems can reflect preexisting social inequalities. In this episode of the Physics World Stories podcast ...

Muon mania: are we finally on the brink of new physics?

The global particle physics community has been energised by two recent results that offer tantalising glimpses of new physics beyond the Standard Model of particle physics. Researchers at CERN’s LHCb experiment have observed something unusual in the way that B mesons decay into leptons – the class of fundamental particle incorporating electrons, muons, taus and their corresponding neutrinos. Meanwhile, researchers at Fermilab may have glimpsed an unknown force at work in the way muons “wobble” ...

Arecibo Observatory: a scientific giant that fell to Earth

1 December 2020 was a dark day for Puerto Rico and the global astronomy community. The iconic Arecibo Observatory collapsed, with the radio telescope’s 900-tonne suspended platform crashing into the 305 m dish below. Warning signs had been there in the preceding months, but that did little to soften the shock felt by the astronomy community. In this episode of the Physics World Stories podcast, Andrew Glester speaks with astronomers about the impact of this dramatic event. Abel Méndez, a planet...

How capable are today’s quantum computers?

Media coverage of quantum computing often focuses on the long term potential for these devices to leave classical computing in the dust. But what about the rudimentary quantum systems that are already being developed and tested by technology companies? What are the latest advances in the field? And what might these systems realistically be able to achieve in the short to medium term? Andrew Glester investigates these questions in the latest episode of the Physics World Stories podcast. The epis...
