‘This book is not just about life, but about discovery itself. It is about error and hubris, but also about wonder and the reach of science. And it is bookended with the ultimate question: How do we define the thing that defines us?’ – Siddhartha Mukherjee, author of The Gene We all assume we know what life is, but the more scientists learn about the living world – from protocells to brains, from zygotes to pandemic viruses – the harder they find it to locate the edges of life, where it begins and ends. What exactly does it mean to be alive? Is a virus alive? Is a foetus? Carl Zimmer investigates one of the biggest questions of all: What is life? The answer seems obvious until you try to seriously answer it. Is the apple sitting on your kitchen counter alive, or is only the apple tree it came from deserving of the word? If we can’t answer that question here on earth, how will we know when and if we discover alien life on other worlds? The question hangs over some of society’s most charged conflicts – whether a fertilized egg is a living person, for example, and when we ought to declare a person legally dead. Life’s Edge is an utterly fascinating investigation by one of the most celebrated science writers of our time. Zimmer journeys through the strange experiments that have attempted to recreate life. Literally hundreds of definitions of what that should look like now exist, but none has yet emerged as an obvious winner. Lists of what living things have in common do not add up to a theory of life. It’s never clear why some items on the list are essential and others not. Coronaviruses have altered the course of history, and yet many scientists maintain they are not alive. Chemists are creating droplets that can swarm, sense their environment, and multiply – have they made life in the lab? Whether he is handling pythons in Alabama or searching for hibernating bats in the Adirondacks, Zimmer revels in astounding examples of life at its most bizarre. He tries his own hand at evolving life in a test tube with unnerving results. Charting the obsession with Dr Frankenstein’s monster and how Coleridge came to believe the whole universe was alive, Zimmer leads us all the way into the labs and minds of researchers working on engineering life from the ground up.

At the beginning of his memoir Life Lived Wild, Adventures at the Edge of the Map, Rick Ridgeway tells us that if you add up all his many expeditions, he’s spent over five years of his life sleeping in tents: “And most of that in small tents pitched in the world’s most remote regions.” It’s not a boast so much as an explanation. Whether at elevation or raising a family back at sea level, those years taught him, he writes, “to distinguish matters of consequence from matters of inconsequence.” He leaves it to his readers, though, to do the final sort of which is which."--Amazon.

Can life exist in the Antarctic ice, in the deep subsurface, in dilute sulfuric acid, in hot springs-even on Mars? What degree of high or low temperature, pressure, or salt concentration can living cells tolerate? In recent years, scientists have discovered many single-cell creatures that exist in-in fact, are perfectly adapted to-extreme environments that were considered uninhabitable just one or two decades ago. In Life on the Edge, author Michael Gross explores how microorganisms adapt to their hostile environments and how they affect our current definition of the "normal" conditions for life. He also describes the vast implications of these extremophiles and other amazing creatures-from potential breakthroughs in medicine and biotechnology to the search for life elsewhere in the universe.

Eighteen-year-old Cayenne barely remembers her mother, who died of breast cancer when Cayenne was four. The women in her family have a history of dying young. Cayenne figures she'll meet the same fate, so she might as well enjoy life now, engaging in death-defying risks like dodging trains and jumping off cliffs with her boyfriend. When Cayenne receives a series of video messages her mother made for her before dying, she isn't sure she wants them. Her aunt Tee has been her true mother figure. But then Aunt Tee tests positive for a BRCA gene mutation—the one that doomed Cayenne's mom—and decides to get a mastectomy to reduce her chances of developing cancer. As Cayenne helps her aunt prepare for the surgery, she finds herself drawn to her mother's messages, with their musings on life, love, and perseverance. For the first time, Cayenne starts to question what it truly means to live life to the fullest, even when death might be written into her DNA.

I loved this book' James Nestor, bestselling author of Breath 'Moving, raw and unflinching' Julia Samuel, bestselling author of This Too Shall Pass 'Incredible storytelling' Dr Rangan Chatterjee, bestselling author of Feel Better in 5 ____________________________________________________________________________ How do you carry on when things go deadly wrong? When Dr Rahul Jandial operated on Karina, an eleven-year-old girl whose spinal cord was splitting in two, he had to make an impossible decision. He followed his head over his gut and Karina was left permanently paralysed, altering both patient and surgeon's lives for ever. This decision would haunt Rahul for decades, a constant reminder of the fine line between saving and damaging a life. As one of the world's leading brain surgeons, Rahul is the last hope for patients with extreme forms of cancer. In treating them, he has observed humanity at its most raw and most robust. He has journeyed to unimaginable extremes with them, guiding them through the darkest moments of their lives. Life on a Knife's Edge is Rahul's poetic and beautifully written account of the resilience, courage and belief he has witnessed in his patients, and the lessons about human nature he has learned from them. It is about the impossible choices he has to make, and the fateful consequences he is forced to live with. From challenging the ethics of surgical practices, to helping a patient with locked-in syndrome communicate her dying wish to her family, Rahul shares his extraordinary experiences, revealing the depths of a surgeon's psyche that is continuously pushed to its limits.
