Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, sweeping over Terra Sabaea, Syrtis Major, the dunes of Elysium, and Mare Sirenum—on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science.In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.Johnson’s fascination with Mars began as a child in Kentucky, turning over rocks with her father and looking at planets in the night sky. She now conducts fieldwork in some of Earth’s most hostile environments, such as the Dry Valleys of Antarctica and the salt flats of Western Australia, developing methods for detecting life on other worlds. Here, with poetic precision, she interlaces her own personal journey—as a female scientist and a mother—with tales of other seekers, from Percival Lowell, who was convinced that a utopian society existed on Mars, to Audouin Dollfus, who tried to carry out astronomical observations from a stratospheric balloon. In the process, she shows how the story of Mars is also a story about Earth: This other world has been our mirror, our foil, a telltale reflection of our own anxieties and yearnings.Empathetic and evocative, The Sirens of Mars offers an unlikely natural history of a place where no human has ever set foot, while providing a vivid portrait of our quest to defy our isolation in the cosmos.

    But the glory of each essay lies in Childs's ability to portray the sometimes brutal beauty of the wilderness, to capture the individual essence of wild creatures, to transport the reader beyond the human realm and deep inside the animal kingdom.

    And unlike dogs, cats offer humans no practical benefit. The truth is they are sadly incompetent mouse-catchers and now pose a threat to many ecosystems. Yet, we love them still.Content:Catacombs Cat's cradle What's the catch? The cats that ate the canaries The cat lobby CAT scan Pandora's litter box Lions and toygers and lykoi Nine likes.

    The threat of the disease kept ships close to home and doomed those vessels that ventured too far from port. The willful ignorance of the royal medical elite, who endorsed ludicrous medical theories based on speculative research while ignoring the life-saving properties of citrus fruit, cost tens of thousands of lives and altered the course of many battles at sea. The cure for scurvy ranks among the greatest of human accomplishments, yet its impact on history has, until now, been largely ignored.From the earliest recorded appearance of the disease in the sixteenth century, to the eighteenth century, where a man had only half a chance of surviving the scourge, to the early nineteenth century, when the British conquered scurvy and successfully blockaded the French and defeated Napoleon, Scurvy is a medical detective story for the ages, the fascinating true story of how James Lind (the surgeon), James Cook (the mariner), and Gilbert Blane (the gentleman) worked separately to eliminate the dreaded affliction.Scurvy is an evocative journey back to the era of wooden ships and sails, when the disease infiltrated every aspect of seafaring life: press gangs "recruit" mariners on the way home from a late night at the pub; a terrible voyage in search of riches ends with a hobbled fleet and half the crew heaved overboard; Cook majestically travels the South Seas but suffers an unimaginable fate. Brimming with tales of ships, sailors, and baffling bureaucracy, Scurvy is a rare mix of compelling history and classic adventure story.

    With the Big Bang, it went from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us? Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.

    David Starr Jordan was a taxonomist, a man possessed with bringing order to the natural world. In time, he would be credited with discovering nearly a fifth of the fish known to humans in his day. But the more of the hidden blueprint of life he uncovered, the harder the universe seemed to try to thwart him. His specimen collections were demolished by lightning, by fire, and eventually by the 1906 San Francisco earthquake—which sent more than a thousand of his discoveries, housed in fragile glass jars, plummeting to the floor. In an instant, his life’s work was shattered. Many might have given up, given in to despair. But Jordan? He surveyed the wreckage at his feet, found the first fish he recognized, and confidently began to rebuild his collection. And this time, he introduced one clever innovation that he believed would at last protect his work against the chaos of the world. When NPR reporter Lulu Miller first heard this anecdote in passing, she took Jordan for a fool—a cautionary tale in hubris, or denial. But as her own life slowly unraveled, she began to wonder about him. Perhaps instead he was a model for how to go on when all seemed lost. What she would unearth about his life would transform her understanding of history, morality, and the world beneath her feet. Part biography, part memoir, part scientific adventure, Why Fish Don’t Exist reads like a fable about how to persevere in a world where chaos will always prevail.

    We know they make your eyes blue, your hair curly or your nose straight. The media tells us that our genes control the risk of cancer, heart disease, alcoholism or Alzheimer's. The cost of DNA sequencing has plummeted from billions of pounds to a few hundred, and gene-based advances in medicine hold huge promise.So we've all heard of genes, but how do they actually work?According to legend, Ernest Hemingway was once given a six-toed cat by an old sea captain, and her distinctive descendants still roam the writer's Florida estate today. Scientists now know that the fault driving this profusion of digits lies in a tiny genetic control switch, miles away (in molecular terms) from the gene that 'makes' toes. And it's the same mistake that gives rise to multi-toed humans too.There are 2.2 metres of DNA inside every one of your cells, encoding roughly 20,000 genes. These are the 'recipes' that tell our cells how to make the building blocks of life, along with myriad control switches ensuring they're turned on and off at the right time and in the right place. But rather than a static string of genetic code, this is a dynamic, writhing biological library. And figuring out how it all works – how your genes make you, you – is a major challenge for researchers around the world.Drawing on stories ranging from six-toed cats and stickleback hips to wobbly worms and zombie genes, geneticist Kat Arney explores the how our genes work, creating a companion reader to the book of life itself.

     Is slipping on a banana peel really as hazardous to your health as the cartoons imply? Answer: Yes. Banana peels ooze a gel that turns out to be extremely slippery. Your foot and body weight provide the pressure. The gel provides the humor (and resulting head trauma). Can you die by shaking someone s hand? Answer: Yes. That's because, due to atomic repulsion, you've never actually touched another person s hand. If you could, the results would be as disastrous as a medium-sized hydrogen bomb. If you were Cookie Monster, just how many cookies could you actually eat in one sitting? Answer: Most stomachs can hold up to sixty cookies, or around four liters. If you eat or drink more than that, you re approaching the point at which the cookies would break through the lesser curvature of your stomach, and then you d better call an ambulance to Sesame Street."

    But evolutionary biologists also point out many examples of contingency, cases where the tiniest change--a random mutation or an ancient butterfly sneeze--caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary freaks? And what does that say about life on other planets?Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be.Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

    Alexander von Humboldt (1769 – 1859) was an intrepid explorer and the most famous scientist of his age. In North America, his name still graces four counties, thirteen towns, a river, parks, bays, lakes, and mountains. His restless life was packed with adventure and discovery, whether he was climbing the highest volcanoes in the world or racing through anthrax-infected Siberia or translating his research into bestselling publications that changed science and thinking. Among Humboldt's most revolutionary ideas was a radical vision of nature, that it is a complex and interconnected global force that does not exist for the use of humankind alone. Now Andrea Wulf brings the man and his achievements back into focus: his daring expeditions and investigation of wild environments around the world and his discoveries of similarities between climate and vegetation zones on different continents. She also discusses his prediction of human-induced climate change, his remarkable ability to fashion poetic narrative out of scientific observation, and his relationships with iconic figures such as Simón Bolívar and Thomas Jefferson. Wulf examines how Humboldt's writings inspired other naturalists and poets such as Darwin, Wordsworth, and Goethe, and she makes the compelling case that it was Humboldt's influence that led John Muir to his ideas of natural preservation and that shaped Thoreau's Walden.With this brilliantly researched and compellingly written book, Andrea Wulf shows the myriad fundamental ways in which Humboldt created our understanding of the natural world, and she champions a renewed interest in this vital and lost player in environmental history and science.

    Why does music evoke such powerful moods? The answers are at last be- coming clear, thanks to revolutionary neuroscience and the emerging field of evolutionary psychology. Both a cutting-edge study and a tribute to the beauty of music itself, This Is Your Brain on Music unravels a host of mysteries that affect everything from pop culture to our understanding of human nature, including: • Are our musical preferences shaped in utero? • Is there a cutoff point for acquiring new tastes in music? • What do PET scans and MRIs reveal about the brain’s response to music? • Is musical pleasure different from other kinds of pleasure?This Is Your Brain on Music explores cultures in which singing is considered an essential human function, patients who have a rare disorder that prevents them from making sense of music, and scientists studying why two people may not have the same definition of pitch. At every turn, this provocative work unlocks deep secrets about how nature and nurture forge a uniquely human obsession.

    In a spirited tour across continents and cultures, Adam Rogers takes us from bourbon country to the world’s top gene-sequencing labs, introducing us to the bars, barflies, and evolving science at the heart of boozy technology. He chases the physics, biology, chemistry, and metallurgy that produce alcohol, and the psychology and neurobiology that make us want it. If you’ve ever wondered how your drink arrived in your glass, or what it will do to you, Proof makes an unparalleled drinking companion.

    Now he gathers the best of his best, updated and expanded upon, to guide readers on a mind-bending tour of the far frontier, and how these advances are radically transforming our lives. From the ways science and technology are fundamentally altering our bodies and our world (the world’s first bionic soldier, the future of evolution) to those explosive collisions between science and culture (life extension and bioweapons), we’re crossing moral and ethical lines we’ve never faced before.As Kotler writes, “Life is tricky sport—and that's the emotional core of this story, the real reason we can’t put Pandora back in the box. When you strip everything else away, technology is nothing more than the promise of an easier tomorrow. It’s the promise of hope. And how do you stop hope?”Join Kotler in this fascinating exploration of our incredible next: a deep dive into those future technologies happening now—and what it means to be a part of this brave new world.
