We live in a time of automation and robotics; the machines run the factories, and AI will soon take all the jobs. And yet, even today, there are certain niche jobs where only an animal will do. Comedian and biologist Simon Watt is out to meet some of them, and the people who train them, study them, and love them. And he asks the key questions: HOW do they do what they do, and WHY, with all our ingenuity, haven't we invented anything that can compete with them?

We start with a business of ferrets (yes, that is their collective noun) at the National Ferret School in Derbyshire, who have swapped rabbit holes and trouser legs for drain-clearing, re-wiring, and laying fibre optic cables. Ferret Trainer James McKay demonstrates why they're perfect for the job, as he casually folds one trainee into a tight pretzel.

Simon visits the HQ of 'Medical Detection Dogs', a training facility in Milton Keynes where dogs are being trained to sniff the tell-tale signs of a host of diseases. You may have heard of their 'cancer dogs', but it goes much further: epilepsy, malaria, Parkinson's, even Covid-19. Dr Claire Guest explains.

Can technology keep up? Maybe. Although we have no real idea exactly HOW dogs do what they do, AI may be on the cusp of solving this puzzle for us. Simon speaks to Dr Andreas Mershin from start-up Realnose, which is developing “electronic noses".

Finally, Simon meets some real heroes. 'HeroRats', to be precise. Not the same species that haunts our sewers, these are African Giant Pouched Rats, and their job as landmine detection specialists is saving lives across Thailand, Mozambique, Cambodia and Zimbabwe. Dr Cynthia Fast from UCLA trains them for the job.

The London Anatomy Office accepts around 350 human bodies donated for medical research and education annually. You may imagine that these bodies are presevered in chemicals for medical students to study over weeks and months. And some are. But many are used - almost fresh - to train surgeons in the procedures which may one day save your life.

Journalist Jenny Kleeman gains rare access to a surgical training course at Brighton and Sussex Medical School which uses these "fresh" donor bodies. She talks to the people who work with them every day and the surgeons who have come to be trained to find out how they feel about the people who have given the ultimate gift and if we still need real human cadavers in medical education.

There can't be many people in the world who've saved lives in hospital emergency rooms and also helped care for the wellbeing of astronauts in space – but Kevin Fong’s career has followed a singular path: from astrophysics and trauma medicine, to working with NASA, to becoming an Air Ambulance doctor.

Kevin is a consultant anaesthetist and professor of public engagement and innovation at University College London. He’s worked on the front line in hospitals, dealing with major incidents and helping shape policy; but he's also stayed true to his childhood passion for space, working on multiple projects with NASA and even going through the astronaut application process himself. As if that wasn’t enough, he’s also become a well-known figure in science broadcasting through his various radio and TV shows.

Speaking to Professor Jim Al-Khalili, Kevin admits it hasn't always been an easy path – but his passion for both space and medicine have got him through. And today, he's channelling his energies into ensuring we protect the NHS's most precious commodity: its staff.

Chemical reactions are the backbone of modern society: the energy we use, the medicines we take, our housing materials, even the foods we eat, are created by reacting different substances together. If we zoom in, it’s the atoms within these substances that rearrange themselves to give rise to new substances with the properties we need.

However, chemical reactions are far from perfect. They're often inefficient and their waste products can be harmful to the environment. Getting to grips with what goes on at the scale of individual atoms has long been a sticking point.

Dame Pratibha Gai has spent much of her career pioneering novel microscopes to bring this seemingly inaccessible atomic world into sharp focus. Now Emeritus Professor of Chemistry at York University, her microscope, known as the environmental transmission electron microscope, is housed in labs around the world. It allows scientists, like herself, to observe chemical reactions in real-time, in exquisite atomic detail, and tinker with them to create products that are not only better for all of us, but also the environment.

Have you ever considered the lighter side of dark matter?
Comedy has proved an unexpectedly succesful way to engage people with science - as today's guest knows first-hand.

Astrophysicist Catherine Heymans is a Professor at the University of Edinburgh and the current Astronomer Royal for Scotland. She’s spent her career studying dark matter and dark energy: the mysterious ingredients that make up an estimated 95% of our cosmos, but which we still know surprisingly little about. Using increasingly powerful telescopes, both on earth and in space, Catherine has spent years building detailed maps of dark matter - even to the extent of capturing rare images of this mysterious cosmic component.

On top of her research achievements, she's committed to making science accessible to all; not least by taking an astronomy-themed comedy show to the Edinburgh Festival and beyond.

In conversation with Professor Jim Al-Khalili, Catherine talks about her passion for sharing the joys of astrophysics - and reveals how health challenges over the last few years have forced her to readdress her career, her ambitions and even her sense of self...

As a young man, traveling in Africa, Tim Coulson - now Professor of Zoology at the University of Oxford - became seriously ill with malaria and was told a second bout would probably kill him. Aged only 20, this brush with his own mortality led him to promise himself he would write a complete guide to science: life, the universe and everything. His aim was to understand the existence of all living things - no mean feat!

Over the course of a colourful career, Tim's work has taken him all over the world: including researching wolves in Yellowstone National Park, little fish called guppies in the rivers of Trinidad and silvereye birds on Heron Island on the Great Barrier Reef. Using complicated mathematical models he builds up a picture of ecosystems seeking to explain how predators impact both evolution and ecosystems. And finally, more than thirty years after he vowed to write the book that would explain everything we know about science, he's done just that.

In conversation with Professor Jim Al-Khalili, Tim talks about his journey from youthful ambition to science demystifier.

Have you ever pondered the fact that the universe is expanding? And not only that, it's expanding at an increasing speed - meaning everything around us is getting further and further away? 

If that isolating thought makes you feel slightly panicked, don't worry: this programme also contains wine! 

Brian Schmidt is a Distinguished Professor of Astrophysics at the Australian National University, known for his work on supernovae: massive explosions that take place when stars come to the ends of their lives. They are among the most energetic events in the universe and incredibly difficult to find; but that’s what his High-Z Supernova Search Team did, identifying enough of these rare and distant explosions to measure just how fast they were moving away from us. 

This led them to the realisation that, contrary to long-held belief in cosmology, the expansion of the universe was speeding up; a discovery which earned Brian a share of the 2011 Nobel Prize for Physics. As if that wasn't enough, he's gone on to discover one of the earliest stars in the universe; run a university; and become a winemaker, at his very own vineyard just outside Canberra. 

In a conversation spanning the genius phraseology of writer Douglas Adams, the importance of pisco sours, and the similarities between astronomy and viticulture, Brian tells Professor Jim Al-Khalili how his supernovae breakthrough paved the way for a revolution in astronomy - and where the field needs to go next...

The celebrated primatologist Jane Goodall died last week at the age of 91. In tribute, we’re re-sharing this interview from 2020, where she reflects on the years she spent living with the wild chimpanzees in Gombe in eastern Tanzania and why she believes the best way to bring about change is to ‘creep into people’s hearts’. 

Jane shot to fame when she appeared on the cover of National Geographic magazine in 1963 and appeared in a documentary film directed by Orson Welles. Her ground breaking observations introduced us to the social and emotional lives of wild chimpanzees and changed our view of what it is to be human. Images of her younger self play-wrestling with baby chimps make Jane feel slightly apprehensive now but at the time she didn’t give it a second thought. However, she did take care to protect her young son. Seeing distressing footage of chimps who were living in captivity, she gave up fieldwork to become an activist, working to liberate chimpanzees that were being used for medical research or sold for meat or as pets, and setting up chimp sanctuaries for animals that were no longer able to live in the wild. For the last thirty years, she has campaigned gently but relentlessly to protect wild animals and wild places, touring the world and performing on stage in front of huge audiences. Her global youth programme, Roots and Shoots has inspired and empowered millions of people to understand and respect nature, leading some to call her ‘the mother Theresa of the environment’. A label she dislikes.

How much information can you extract from a burnt fragment of human bone?

Quite a lot, it turns out - not only about the individual, but also their broader lives and communities; and these are the stories unearthed by Jacqueline McKinley, a Principal Osteoarchaeologist with Wessex Archaeology.

During her career, Jackie has analysed thousands of ancient burial sites across the British Isles, bringing to life the old traditions around death via often cremated human remains. She's also assisted criminal investigators with forensic analysis, and contributed to some of the UK's best-loved archaeological TV shows.
And one thing she’s absolutely clear about: far from being macabre, osteoarchaeology is more about the living, than the dead...

In conversation with Professor Jim Al-Khalili, Jackie talks about the stories we can derive from skeletal remains, how western attitudes to death have gone through a major recent shift, and why she's kept some of her late father's bones.

Surgeons often have to deal with the consequences of violent attacks - becoming all too familiar with patterns of public violence, and peaks around weekends, alcohol-infused events and occasions that bring together groups with conflicting ideals.

Professor Jonathan Shepherd not only recognised the link between public violence and emergency hospital admissions, he actually did something about it.

As a senior lecturer in Oral and Maxillofacial Surgery in the early 1980s, Jonathan started looking into this trend - and his research revealed that most violent assaults resulting in emergency hospital treatment are not reported to police.

As a result, he devised the ‘Cardiff Model for Violence Prevention’: a programme where hospitals share data about admissions relating to violent attacks with local authorities. He also went on to study various aspects of violent assault and deliver evidence-based solutions - from alcohol restrictions in hotspots, to less breakable beer glasses in pubs.

The impacts have been significant, delivering reductions in hospital admissions and in violent attacks recorded by police; not only in Cardiff, but in cities around the world where the model is used. Today, as an Emeritus Professor of Oral and Maxillofacial Surgery at Cardiff University - where he’s also Director of their Crime, Security and Intelligence Innovation Institute - Jonathan continues to bring together the medical sector with local authorities, finding practical ways to make cities and their residents safer.

But his career, straddling the worlds of practise, science and policy, is an unusual one; here he talks to Professor Jim Al-Khalili about what drove him to make a difference.
