The stewards of Earth, these organisms transformed the chemistry of our planet to make it habitable for plants, animals, and us. Life's Engines takes readers deep into the microscopic world to explore how these marvelous creatures made life on Earth possible--and how human life today would cease to exist without them.Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built--and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.A vibrantly entertaining book about the microbes that support our very existence, Life's Engines will inspire wonder about these elegantly complex nanomachines that have driven life since its origin. It also issues a timely warning about the dangers of tinkering with that machinery to make it more "efficient" at meeting the ever-growing demands of humans in the coming century.

    The expedition was described by the two men in Sea of Cortez, published in 1941. The day-to-day story of the trip is told here in the Log, which combines science, philosophy and high-spirited adventure.Log from the Sea of Cortez includes the narrative of the journey and the essay “About Ed Ricketts.” It does not include pictures and detailed descriptions of the species collected by Steinbeck and Ricketts.

    Prusiner received a Nobel Prize, the world's most prestigious award for achievement in physiology or medicine. That he was the sole recipient of the award for the year was entirely appropriate, for his struggle to identify the agent responsible for ravaging the brains of animals suffering from scrapie and mad cow disease, and of humans with Creutzfeldt-Jakob disease, had been waged largely alone and in some cases in the face of strenuous disagreement.   In this book, Prusiner tells the remarkable story of his discovery of prions—infectious proteins that replicate and cause disease but surprisingly contain no genetic material—and reveals how superb and meticulous science is actually practiced using talented teams of researchers who persevere. He recounts the frustrations and rewards of years of research and offers fascinating portraits of his peers as they raced to discover the causes of fatal brain diseases. Prusiner’s hypothesis, once considered heresy, now stands as accepted science and the basis for developing diagnoses and eventual cures. He closes with a meditation on the legacy of his discovery: What will it take to cure Alzheimer’s, Parkinson’s, Lou Gehrig’s and other devastating diseases of the brain?

    The authors move deftly across a dazzling array of topics—from the dynamics of the bacterial realm, to the connection between sex and death, to theories of spirit and matter. They delve into the origins of life, offering the startling suggestion that life—not just human life—is free to act and has played an unexpectedly large part in its own evolution. Transcending the various formal concepts of life, this captivating book offers a unique overview of life’s history, essences, and future.Supplementing the text are stunning illustrations that range from the smallest known organism (Mycoplasma bacteria) to the largest (the biosphere itself). Creatures both strange and familiar enhance the pages of What Is Life? Their existence prompts readers to reconsider preconceptions not only about life but also about their own part in it.

      In 1875, tuberculosis was the deadliest disease in the world, accountable for a third of all deaths. A diagnosis of TB—often called consumption—was a death sentence. Then, in a triumph of medical science, a German doctor named Robert Koch deployed an unprecedented scientific rigor to discover the bacteria that caused TB. Koch soon embarked on a remedy—a remedy that would be his undoing.   When Koch announced his cure for consumption, Arthur Conan Doyle, then a small-town doctor in England and sometime writer, went to Berlin to cover the event. Touring the ward of reportedly cured patients, he was horrified. Koch’s "remedy" was either sloppy science or outright fraud.   But to a world desperate for relief, Koch’s remedy wasn’t so easily dismissed. As Europe’s consumptives descended upon Berlin, Koch urgently tried to prove his case. Conan Doyle, meanwhile, returned to England determined to abandon medicine in favor of writing. In particular, he turned to a character inspired by the very scientific methods that Koch had formulated: Sherlock Holmes.   Capturing the moment when mystery and magic began to yield to science, The Remedy chronicles the stunning story of how the germ theory of disease became a true fact, how two men of ambition were emboldened to reach for something more, and how scientific discoveries evolve into social truths.
