Technofossils - Sarah Gabbott, Mark Miodownik and Aurie Styla Aug 06, 2025

Show notes

Brian Cox and Robin Ince dig deep into the strata of an imagined human history to unearth the curious concept of technofossils. Joined by paleobiologist Sarah Gabbott, material scientist Mark Miodownik and comedian and tech enthusiast Aurie Styla the panel unearth how the everyday objects that we throw away today compare to fossils of the past. Together, the panel investigates how these modern artifacts could degrade over time to become the fossils of the future. From old smartphones buried in bedside drawers to sprawling landfill sites, they imagine how these remnants of the Anthropocene might puzzle future archaeologists—and speculate on what these researchers might infer about our technology, customs, and way of life.

The Mighty Spud - Sandy Knapp, Glenn Bryan and Susan Calman Jul 30, 2025

Show notes

Robin Ince and Brian Cox get out the ketchup and peel back the layers of one of the most versatile and beloved foods - potatoes. From the science of starch to the surprising role potatoes have played in history, we’re digging deep to uncover the truth behind the mighty spud. Chipping into the conversation are botanist Sandy Knapp, geneticist Glenn Bryan and potato passionate comedian Susan Calman. Susan is astonished to learn that the potatoes lining our supermarket shelves all belong to a single species and once she discovered the rich diversity of wild potato species in South America, she’s already planning her next holiday to visit them! Plus we end the episode on a tuber-powered musical note as Helen Anahita-Wilson plays the monkey cage theme song on none other than a potato keyboard!

Should We Settle in Space? - Tim Peake, Kelly Weinersmith and Alan Davies Jul 16, 2025

Show notes

Brian Cox and Robin Ince blast off into a cosmic controversy as they ask, should humanity become an interplanetary species? At Harwell Campus, a space science innovation hub, they’re joined by astronaut Tim Peake, biologist and Royal Society prize winning author Kelly Weinersmith, and comedian Alan Davies to explore the science, ethics, and challenges of settling on Mars or on the Moon. Are we bold pioneers venturing into the unknown, or just reckless tenants abandoning Earth in search of a new abode? Our panel discuss whether space settlement is inevitable in humanity’s near future and how pushing the boundaries of space exploration could make extra-terrestrial travel more accessible to the masses. From sourcing materials, to surviving radiation, and even growing potatoes from poo, they tackle what it really would take to live a life beyond Earth!

201st Birthday Bonanza - Mel Giedroyc, Deborah Meaden and Nish Kumar Jul 09, 2025

Show notes

Get ready for a landmark episode of The Infinite Monkey Cage as we celebrate our 201st show! Brian Cox and Robin Ince invite a lively panel of celebrity guests to pose their burning scientific questions to a top-tier team of scientists. Mel Giedroyc is tunnelling into the world of engineering, asking how we build and operate trains under some of the world’s busiest cities? Mel has found a new best friend in, Isabel Coman, Director of Engineering at Transport for London, who is here to guide her through the particulars of subterranean transport systems. Deborah Meaden, entrepreneur and investor, is delving into the emotional lives of animals - do our furry, feathered, and scaly companions have feelings like grief in the way we do? Helping her to sniff out the science of animal emotions is Dr Liz Paul, a comparative psychologist from the University of Bristol. Comedian Nish Kumar wants to know - are we totally screwed when it comes to climate change, or is there still hope? Helping him unpack tipping points, rising temperatures, and how we might turn the tide is climate scientist Ed Hawkins from the University of Reading.

Nature's Shapes - Dave Gorman, Sarah Hart and Thomas Woolley Mar 26, 2025

Show notes

Brian Cox and Robin Ince unpick the hidden codes behind the shapes we see in nature with mathematicians Sarah Hart & Thomas Woolley and comedian Dave Gorman.

The panel marvel at how evolution so often beats mathematicians to finding the most elegant solutions, after all, it’s had millennia to experiment. How do trees achieve the optimal distribution of leaves and why are tortoise shells so geometrically exciting?

Plus we learn why the cheetah got its spots, thanks to the work of Thomas Woolley’s mathematical hero, Alan Turing, how numbers can be more or less irrational, and why Dave Gorman has a vendetta against oblongs.

The Sound of Music - Brian Eno, Sam Bennett and Trevor Cox Mar 19, 2025

Show notes

Brian Cox and Robin Ince explore the history of music recording, joined by acoustics professor Trevor Cox, music professor Sam Bennett and musician and producer Brian Eno. Together they guide us through the evolution of sound recording, a space in which technology hasn’t stood still since its advent in the mid-1800s. We hear the very first recognisable recording of a voice made with a brush making marks in soot and put a spotlight on the Fairlight CMI, a revolutionary digital synthesizer of the '70s, used in Brian’s records (Cox & Eno’s!)

Plus, we run an audio experiment with our live audience who turn themselves into our in-house digital orchestra, with the help of their mobile phones. Now that lots of people have several devices that can play sound, new technology is harnessing this to create a more immersive experience – which (kind of) worked in our experiment!

Saturn v Jupiter - Katherine Parkinson, Paul Abel and Michele Dougherty Mar 12, 2025

Show notes

Brian Cox and Robin Ince referee as Saturn and Jupiter square up to each other in a planetary face-off. Representing Team Saturn is space physicist Professor Michele Dougherty, and in the opposite corner is Dr Paul Abel on Team Jupiter. Katherine Parkinson judges this cosmic contest, casting the final vote to decide who will be awarded the coveted Kuiper Belt.

It is not all about looks of course, but it is a significant factor in a first impression. Both Saturn and Jupiter score highly in this department, boasting magnificent icy rings and colourful stripes respectively. But what lies beneath their aesthetically pleasing exteriors? How do the planets compare on the inside?

The gas giants have been subjects of investigation for many years, with historic missions like Galileo and Cassini uncovering their secrets. But they aren’t alone, each planet is surrounded by its own mini solar system of moons, which get space scientists just as excited as their parent planets do. Both Jupiter and Saturn have moons which are hot contenders in the search for extraterrestrial life and our panel discuss the future plans to explore them.

Adventures on Ice - Darren Harriott, Liz Morris, Christoph Salzmann and Felicity Aston Mar 05, 2025

Show notes

Robin Ince and Brian Cox venture into the captivating and surprisingly mysterious realm of ice. Joining them on this cool adventure are former ice dancer Darren Harriott, glaciologist Liz Morris, polar explorer Felicity Aston and ice chemist Christoph Salzmann.

From beautifully formed snowflakes to ice shelves in Antarctica, our guests discuss the fascinating science suspended in solid water and how much is still to be discovered. With the help of a gin and tonic they explore the properties of ice - like why it floats and how there are 20 phases of ice, three of which were accidentally discovered by our guest Christoph. Darren shares his respect and fear for ice having learnt to dance and ice-skate on it. Liz discusses how analysing deep ice can provide a window into our past climate whilst also helping us understand our present one and why penguins can be problematic. Polar explorer Felicity explains how being able to read the colours, shapes and sounds of the ice have helped to keep her alive as she's traversed the highly inhospitable (but also incredibly beautiful) polar regions.
