Asel Sartbaeva on protecting vaccines with a pinch of sand
Vaccines save millions of lives each year but, to work, most need to be kept cold throughout their journey, from the factory where they’re made to the clinic where they’re given. This relies on what’s known as the cold chain, a global network of fridges, freezers and icepacks. The chain is not only expensive to maintain, it’s incredibly vulnerable to breaking. In low- and middle- income countries,
Robert Ballard on finding the Titanic and other deep-sea discoveries
Finding the wreck of the Titanic would be a career-defining achievement for most people. For oceanographer Robert Ballard, it's just one chapter in a life packed full of extraordinary marine exploration.Bob located the world-famous shipwreck in 1985, but even before that, he’d helped prove the existence of hydrothermal vents: underwater formations surrounded by ecosystems flourishing in the ocean’
Gillian Forrester on gesturing gorillas, babbling babies and the origins of human language
What do the very first writhing movements of babies have in common with orangutans solving problems for food? Well, according to Gillian Forrester they may both offer clues about how we humans developed language.Working with her great ape colleagues, Gilly Forrester – Professor of Comparative Cognition at the University of Sussex – has dedicated her career to finding out how we became the talkativ
David Canter on how psychology can save lives and catch killers
Although books and movies might suggest otherwise, catching criminals is of course less about hunches and gut instinct, and more about gruelling analysis of hard data - including when it comes to the psychological side.David Canter is an Emeritus Professor of Psychology at the University of Liverpool, who took exactly this approach in the 1980s when he was asked to help police track down a serial
Edith Heard on unravelling the mystery of X-chromosome inactivation

Jens Juul Holst on the gut hormone discovery behind weight-loss drugs
As recently as a few years ago, the idea of a self-administered injection that would deliver proven weight-loss results might have sounded fantastical. Today, these medications are a reality and a global phenomenon; hailed in many quarters as “miracle drugs" for their success in treating obesity and diabetes. They do this by replicating a gut hormone called GLP‑1, which tells the brain you’ve eate
Jim Ashworth-Beaumont on how a near-fatal accident made him a better clinician
