Tori Herridge on ancient dwarf elephants and frozen mammoths
Elephants are the largest living land mammal and today our plant is home to three species: the African bush elephant, the African forest elephant, and the Asian elephant.But a hundred thousand years ago, in the chilly depths of the Ice Age, multiple species of elephant roamed the earth: from dog-sized dwarf elephants to towering woolly mammoths.These gentle giants' evolutionary story and its parallels with that of humankind has long fascinated Dr Tori Herridge, a senior lecturer in evolutionary biology at the University of Sheffield, where - as a seasoned science broadcaster - she's also responsible for their Masters course in Science Communication.Tori has spent much of her life studying fossil elephants and the sites where they were excavated; trying to establish facts behind relics that are far beyond the reach of Radio Carbon Dating. To date she's discovered dwarf mammoths on Mediterranean islands, retraced the groundbreaking Greek expedition of a female palaeontologist in the early 1900s, and even held an ancient woolly mammoth’s liver. (Verdict: stinky.)But as she tells Profesor Jim Al-Khalili, this passion for fossil-hunting is not just about understanding the past: this information is what will help us protect present-day elephants and the world around them for future generations.Presented by Jim Al-Khalili

Sir Magdi Yacoub on pioneering heart transplant surgery
What does it take to earn the nickname, ‘The Leonardo da Vinci of heart surgery’?That's the moniker given to today's guest - a man who pioneered high-profile and often controversial procedures, but also helped drive huge medical progress; carrying out around 2,000 heart transplants and 400 dual heart-lung transplants during his 60-year career.Sir Magdi Yacoub is Emeritus Professor of Cardiothoracic Surgery at Imperial College London, and Director of Research at Harefield Hospital’s Magdi Yacoub Institute.
Inspired by a surgeon father and impacted by the tragic early death of his aunt from a heart condition, his medical career includes various surgical firsts alongside numerous research projects, to further our understanding of and ability to treat heart disease. He headed up the teams that discovered it is possible to reverse heart failure, and that successfully grew part of a human heart valve from stem cells for the first time. But it hasn't always been plain sailing. At times, his work – such as early, unsuccessful transplant attempts, or using a baboon as a life-support system for a baby – attracted serious public criticism.Speaking to Professor Jim Al-Khalili, Sir Magdi reflects on the highs and lows of his cardio career, and offers his advice to the next generation of surgeons and researchers hoping to make their mark in heart medicine.

Tim Peake on his journey to becoming an astronaut and science in space
What's it like living underwater for two weeks? What's the trickiest part of training to be an astronaut? What are the most memorable sights you see from space?
Several extreme questions, all of which can be answered by one man: Major Tim Peake.After a childhood packed with outdoor adventures, via the Cub Scouts and school Cadet Force, Tim joined the British Army Air Corps and became a military flying instructor then a test pilot; before eventually being selected as a European Space Agency (ESA) astronaut.In 2015, Tim became the first British ESA astronaut to visit the International Space Station. Over the course of a six-month mission, he took part in more than 250 scientific experiments and worked with more than two million schoolchildren across Europe.In a special New Year’s episode recorded in front of an audience at London’s Royal Society, Professor Jim Al-Khalili talks to Tim about his lifelong passion for adventure, the thrill of flight and why scientific experiments in space are so important.Presented by Jim Al-Khalili

Anna Korre on capturing carbon dioxide and defying expectations
As the famous frog once said, it's not easy being green. And when it comes to decarbonising industry, indeed, reducing emissions of all sorts, the task is a complex one. Fossil fuels are used to manufacture some of mankind’s most ubiquitous products, from plastics to cement to steel; and even in areas where we’re trying to improve our footprint, there are repercussions. Mining lithium for electric car batteries isn’t exactly without impact. Add to the mix stories of corporations prioritising profits, and governments focusing on short-term popular policies – and it would be easy to feel disheartened.Professor Anna Korre says her role is to be the champion of science in this debate: providing clear evidence to help reduce environmental impacts, while allowing vital production processes to continue. Anna is an environmental engineer at Imperial College London and Co-Director of the university’s Energy Futures Lab. Her work has led to a risk model that's now used in mining operations around the world – and her current research into sub-surface CO2 storage could hold the key to decarbonising British industry. But as she tells Jim Al-Khalili, social and familial expectations when she was growing up in her native Greece meant her succesful career in engineering very nearly didn't happen...Presented by Jim Al-Khalili

Rosalie David on the science of Egyptian mummies
Rosalie David is a pioneer in the study of ancient Egypt. In the early 1970s, she launched a unique project to study Egyptian mummified bodies using the techniques of modern medicine. Back then, the vast majority of Egyptologists regarded mummies as unimportant sources of information about life in ancient Egypt. Instead they focussed on interpreting hieroglyphic inscriptions, the written record in papyrus documents and archaeological remains and artefacts. Rosalie David proved that the traditionalists were quite wrong.Professor David’s mummy research started at the Manchester Museum when she began to collaborate with radiologists at the nearby Manchester Royal Infirmary, taking the museum’s mummies for x-rays at the hospital. Her multi-disciplinary team later moved to a dedicated institute at the University of Manchester, the KNH Centre for Biomedical Egyptology. Over the decades, the team there has made remarkable discoveries about disease and medicine in ancient Egyptian society, providing a new perspective on the history of medicine and giving extraordinary insights into the lives of individuals all those years ago.Rosalie tells Jim Al-Khalili about her journey from classics and ancient history to biomedicine, including some of her adventures in Egypt in the 1960s. She talks about some of her most significant research projects, and the 21st Century forensic detective work on the mummy of a young woman which revealed a gruesome murder 3,000 years ago...Presented by Jim Al-Khalili
