In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field—the study of life’s diversity and relatedness at the molecular level—is horizontal gene transfer (HGT), or the movement of genes across species lines. It turns out that HGT has been widespread and important. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection—a type of HGT.David Quammen chronicles these discoveries through the lives of the researchers who made them—such as Carl Woese, the most important little-known biologist of the twentieth century; Lynn Margulis, the notorious maverick whose wild ideas about “mosaic” creatures proved to be true; and Tsutomu Wantanabe, who discovered that the scourge of antibiotic-resistant bacteria is a direct result of horizontal gene transfer, bringing the deep study of genome histories to bear on a global crisis in public health.

    “They’re just fantastic! Then I remembered, Ed you’re an anesthesiologist…f*cking hell! I can’t believe that…”.  I like to think I’m an inspiration to all budding doctors that anything is achievable.Ed is a sleepless anesthesiologist. His shifts involve snatching five-minute lunch breaks in the staff bathrooms, navigating emergencies and living with the all too terrifying sense of responsibility. And that was before Coronavirus arrived, which quickly turned his job into a nightmare queue of struggling with ill-fitting PPE, balancing staff shortages and intubating Covid-19 patients who can’t breathe on their own.Hilariously funny and moving, Catch Your Breath follows Ed’s journey from bewildered medical student in Aberdeen to unflinching anesthesiologist on the NHS frontline. It offers a unique insight into life on the hospital wards during the pandemic, while also sharing the hope that we will all get through this.

    As recently as 1918, a pandemic of influenza claimed over 50 million lives worldwide. The advent of drugs and vaccines led to an era of hope when we thought our battles with infectious disease were won, but our optimism has been eroded by the recognition that many pathogens have the capacity to transform themselves and escape our efforts to eradicate them. Are we now facing an inevitable repeat of a calamity such as the 1918 influenza pandemic or the Black Death? Can we anticipate and thwart such an event, or are we wilfully creating the conditions that would promote the emergence of new and highly virulent human infectious disease?Sunetra Gupta is Professor of Theoretical Epidemiology at the University of Oxford specialising in infectious diseases. She holds a bachelor's degree from Princeton University and a Ph.D. from the University of London.

    Yet when it comes to fungi, culinary uses are only the tip of the iceberg. Throughout history fungus has been prized for its diverse properties—medicinal, ecological, even recreational—and hasspawned its own quirky subculture dedicated to exploring the weird biology and celebrating the unique role it plays on earth.

    It contains sketches of orange growers, orange botanists, orange pickers, orange packers, early settlers on Florida's Indian River, the first orange barons, modern concentrate makers, and a fascinating profile of Ben Hill Griffin of Frostproof, Florida who may be the last of the individual orange barons. McPhee's astonishing book has an almost narrative progression, is immensely readable, and is frequently amusing. Louis XIV hung tapestries of oranges in the halls of Versailles, because oranges and orange trees were the symbols of his nature and his reign. This book, in a sense, is a tapestry of oranges, too—with elements in it that range from the great orangeries of European monarchs to a custom of people in the modern Caribbean who split oranges and clean floors with them, one half in each hand.

    In this updated edition of the classic work, Mark Pendergrast reviews the dramatic changes in coffee culture over the past decade, from the disastrous “Coffee Crisis” that caused global prices to plummet to the rise of the Fair Trade movement and the “third-wave” of quality-obsessed coffee connoisseurs. As the scope of coffee culture continues to expand, Uncommon Grounds remains more than ever a brilliantly entertaining guide to the currents of one of the world’s favorite beverages.

    But as a new century approached, appetites broadened, and David Fairchild, a young botanist with an insatiable lust to explore and experience the world, set out in search of foods that would enrich the American farmer and enchant the American eater.Kale from Croatia, mangoes from India, and hops from Bavaria. Peaches from China, avocados from Chile, and pomegranates from Malta. Fairchild's finds weren't just limited to food: From Egypt he sent back a variety of cotton that revolutionized an industry, and via Japan he introduced the cherry blossom tree, forever brightening America's capital. Along the way, he was arrested, caught diseases, and bargained with island tribes. But his culinary ambition came during a formative era, and through him, America transformed into the most diverse food system ever created.
