Episode notes
From humble beginnings in his native Sri Lanka, to a more than 40 year academic career at Queen’s University Belfast, Prof. AP (Amilra Prasanna) De Silva’s research into molecular photosensors has led to a pioneering career in that’s evolved from chemistry to medical diagnostics on one hand, to information processing on the other. Prof. De Silva challenged cultural expectations and overcame the lack of opportunities in chemistry that were available in Sri Lanka in the early 1970s. He first moved to Belfast to pursue research in photochemistry at Queen’s University. Inspired by his…

The Life Scientific: Jehane Ragai
Ever heard of the unsuccessful Dutch painter who decided to humiliate his critics by forging Vermeers, which the artworld subsequently dubbed 'masterpieces'? Or the businessman who bought a Marc Chagall painting that he displayed with pride for years, before a television investigation revealed to his horror that it was a fake? Today we're exploring the scientific techniques used to reveal forged artworks - and bring down scammers still trying to make millions from fake masterpieces. Jehane Ragai is an Emeritus Professor of Chemistry at the American University in Cairo, with a passion for…

The Life Scientific: Tony Juniper
Tony Juniper is an environmentalist who has worn many hats, over the course of his career. After developing a passion for birds in childhood, his first job saw him working to save endangered parrots - including a successful effort to bring back the Spix's macaw from the edge of extinction. Tony went on to hold leading campaigning roles with some of the world's best known environmental organisations, from Friends of The Earth to the World Wildlife Fund. He also acted as an advisor to King Charles's International Sustainability Unit and co-authored three books with the monarch. Today, Tony has…

The Life Scientific: Pierre Friedlingstein
The COP30 climate summit is taking place in the Brazilian city of Belém, a gateway to the Amazon rainforest, which continues to face widespread deforestation. We all know that our climate is changing and that we are largely responsible for this, but we can’t tackle the problem unless we understand what’s going on. One scientist who’s done more than most to rectify this is Professor Pierre Friedlingstein. He’s a prominent climate scientist and Chair in Mathematical Modelling of the Climate System at Exeter University. His models have transformed our understanding of climate change, revealing…

The Life Scientific: Julia Simner
Imagine if you were listening to an opera or a Taylor Swift concert, and as the lights in the auditorium dimmed, the music was accompanied by a rainbow of colours only you could see. Perhaps while listening to your friends talking, you simultaneously experience a smorgasbord of tastes, with different words evoking different flavours, maybe a delicious ice cream, or something as disgusting as ear wax... This merging of the senses is known as synaesthesia, and it’s the rich research world of neuropsychologist Professor Julia Simner. Julia runs the Multisense lab at the University of Sussex and…

The Life Scientific: Caroline Smith
Caroline Smith is passionate about space rocks, whether they’re samples collected from the surface of asteroids and the Moon and hopefully Mars one day soon, or meteorites, those alien rock fragments that have survived their fiery descents through our atmosphere to land here on Earth. She is Head of Collections and Principal Curator of Meteorites at the Natural History Museum, home to one of the finest meteorite collections in the world. Her interest in rocks began while wandering the foothills of the Rocky Mountains, as a child, picking up the ones that caught her eye and bashing them with…

The Life Scientific: Eleanor Schofield
In July 1545, King Henry VIII watched from Southsea Castle on England's south coast as his fleet sailed out to face the French - only to witness his prized warship, the Mary Rose, sink before his eyes. Raised from the Solent in 1982, the ship is now the centrepiece of the Mary Rose Museum, along with thousands more artefacts that were recovered from the seabed. But keeping the 500-year-old ship and its associated Tudor relics in good condition is no small task, which is where Dr Eleanor Schofield comes in. As Director of Collections at the Mary Rose Trust and a materials engineer by…

The Life Scientific: Peter Knight
There are problems and tasks so hard and complicated that it would take today’s most powerful supercomputers millions of years to crack them. But in the next decade, we may well have quantum computers which could solve such problems in seconds. Professor Sir Peter Knight is a British pioneer in the realms of quantum optics and quantum information science. During his three decades as a researcher at Imperial College London, he has advanced our understanding of the physics which underpins how quantum computers work. Quantum optics was a new field of physics at the start of Peter Knight’s…

Frontiers of Earth Science
The very latest developments in the world of Earth science with Roland Pease, recorded at the American Geophysical Union (AGU) meeting in New Orleans, where thousands of Earth, atmospheric, glacial, ocean and hydrologic scientists come together to promote discovery in Earth science for the benefit of humanity. Twenty years on, we discuss the enduring lessons from the Hurricane Katrina disaster of 2005, hearing from Lieutenant General Russel Honoré who led the military relief effort, and Roland speaks to Jill Trepanier, hurricane climatologist from Louisiana State University. We also hear…

Frontiers of Space Science
The very latest developments in the world of space science with Roland Pease, recorded at the American Geophysical Union (AGU) meeting in New Orleans, where thousands of space and planetary scientists come together to promote discovery in space science for the benefit of humanity. Roland talks to Andy Rivkin, planetary astronomer at the Johns Hopkins University Applied Physics Laboratory, about planetary defence from asteroids, including the small potential for asteroid 2024 YR4 to hit the moon in 2032. We hear from Craig DeForest, principle investigator for the PUNCH mission (Polarimeter to…

What is Quantum?
Quantum theory – our best understanding of the world at the smallest level – is famously weird and notoriously confusing. It’s a theory that seems to say particles can be in two places at once, or somehow “know” if you’re looking at them. Or at least, that’s what you might have heard. But is that really what quantum theory tells us about reality? To find out, presenter Marnie Chesterton travels to the birthplace of quantum theory: the remote, windswept island of Helgoland. Here, a century ago, a young scientist called Werner Heisenberg made a leap of understanding that laid the foundations…
