Tim Coulson on how predators shape ecosystems and evolution
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.Presented by Jim Al-Khalili

Liz Morris on Antarctic adventures and the melting polar ice sheets
A frozen, white world at the far-reaches of the globe, where you're surrounded by snow and silence, might sound rather appealing. Factor in temperatures that drop to -57°C and a few of us might be put off - but for glaciologist Liz Morris, that's very much her happy place.Liz is an Emeritus Associate at the University of Cambridge’s Scott Polar Research Institute, and was among the first British women scientists to work on the planet’s coldest continent, Antarctica. Over the course of her career, Liz has gathered vital data on polar ice sheets and how they’re affected by climate change. She's also made numerous research trips across the Greenland Ice Shelf, and has a glacier named after her in Antarctica.In conversation with Professor Jim Al-Khalili, Liz discusses her fascination with glaciers and ice - and explains her unwavering determination to break into what was once a heavily male-dominated field.

Anthony Fauci on a medical career navigating pandemics and presidents
Welcome to a world where medicine meets politics: a space that brings together scientific research, government wrangling, public push-back and healthcare conspiracies…Dr Anthony Fauci was the Director of America’s National Institute of Allergy and Infectious Diseases for nearly four decades, during which time he not only helped study, treat and prevent viruses such as HIV/AIDS and Covid-19; he also advised seven US Presidents, from Ronald Regan through to Joe Biden.Along the way, Tony Fauci's picked up a public profile and taken a fair amount of flack; not least because of his complicated relationship with President Donald Trump. But he's also made great strides in medical research and policy, from working with activists who initially challenged him on the government response to HIV/AIDS - to spearheading the USA's PEPFAR project to share vital medication with developing nations.In a candid conversation with Professor Jim Al-Khalili, Tony discusses his childhood in Brooklyn, the dark early days of the HIV/AIDS epidemic, lessons from the Covid-19, his hopes and fears for the future of American health policy – and his reaction to that pre-emptive pardon from President Biden.Presented by Jim Al-Khalili
