When Dr Ben Goldacre saw someone on daytime TV dipping her feet in an 'Aqua Detox' footbath, releasing her toxins into the water, turning it brown, he thought he'd try the same at home. 'Like some kind of Johnny Ball cum Witchfinder General', using his girlfriend's Barbie doll, he gently passed an electrical current through the warm salt water. It turned brown. In his words: 'before my very eyes, the world's first Detox Barbie was sat, with her feet in a pool of brown sludge, purged of a weekend's immorality.' Dr Ben Goldacre is the author of the Bad Science column in the Guardian. His book is about all the 'bad science' we are constantly bombarded with in the media and in advertising. At a time when science is used to prove everything and nothing, everyone has their own 'bad science' moments from the useless pie-chart on the back of cereal packets to the use of the word 'visibly' in cosmetics ads.

    It’s so bound up with our deepest feelings that emotional trauma causes it to change shape.Practising cardiologist Sandeep Jauhar beautifully weaves his own experiences with the defining discoveries of the past to tell the story of our most vital organ. He looks at some of the pioneers who risked their careers and their patients’ lives to better understand the heart. People like Daniel Hale Williams, who performed the world’s first documented heart surgery, and Wilson Greatbatch, who accidentally invented the pacemaker.Amid gripping scenes from the operating theatre, Jauhar interweaves stories about the patients he’s treated with the moving tale of his family’s own history of heart problems, from his grandfather’s sudden death in India – an event that sparked his life-long obsession – to the ominous signs of how he himself might die.He also confronts the limits of medical technology and argues that future progress will be determined more by how we choose to live rather than by any device we invent.
