The Kaguya Lunar Atlas: The Moon in High Resolution
by Charles A. Wood Motomaro ShiraoIn late 2007, the Japanese Space Exploration Agency (JAXA) placed the Kaguya/ Selene spacecraft in orbit around the Moon to probe the Moon’s surface and interior. But unlike previous lunar orbiters, Kaguya carries a high definition television camera (HDTV) sent beyond Earth orbit. Sponsored by the Japanese NHK TV network, the HDTV has amazed both scientists and the public with its magnificent views of the lunar surface. What makes these images so much more engaging than standard vertical view lunar photography is that they are taken looking obliquely along the flight path. Thus, they show the Moon as it would be seen by an astronaut looking through a porthole window while orbiting only 100 km above the lunar surface. This is the view we all would wish to have but are never likely to, except vicariously through the awe-inspiring Kaguya HDTV images. Each page features a HDTV image with a map of the entire Moon on the upper left showing where the image is located. On the upper right is a 100-150 word description. Seeing the Moon is not intended solely for lunar scientists who are striving to work out the mysteries of the Moon’s origin and evolution. Everyone can appreciate the natural beauty and be entranced by the view of the nearby world where humans may one day live.

The Kihansi Spray Toad (Ecological Studies #254)
by William D. NewmarkThe captive breeding and reintroduction of highly threatened species are among the most challenging conservation interventions and often represent the final tool in a comparatively small toolbox to conserve rapidly declining species. This book details the species recovery program that was designed and implemented over two decades to conserve the Kihansi Spray Toad (Nectophrynoides asperginis), an extinct-in-the-wild tropical amphibian. More than 20 international and national institutions were involved in the design and implementation of the species recovery program. This complex two-decade effort highlights the challenges of conserving highly threatened tropical amphibians and integrating conservation with development in the 21st century. This volume will appeal to biologists, conservation and development practitioners, and institutions and individuals concerned about the conservation of biodiversity.
The Kill Chain: Defending America in the Future of High-Tech Warfare
by Christian BroseFor generations of Americans, our country has been the world's dominant military power. How the US military fights, and the systems and weapons that it fights with, have been uncontested. That old reality, however, is rapidly deteriorating. America's traditional sources of power are eroding amid the emergence of new technologies and the growing military threat posed by rivals such as China. America is at grave risk of losing a future war.As Christian Brose reveals in this urgent wake-up call, the future will be defined by artificial intelligence, autonomous systems, and other emerging technologies that are revolutionizing global industries and are now poised to overturn the model of American defense. This fascinating, if disturbing, book confronts the existential risks on the horizon, charting a way for America's military to adapt and succeed with new thinking as well as new technology. America must build a battle network of systems that enables people to rapidly understand threats, make decisions, and take military actions, the process known as "the kill chain." Examining threats from China, Russia, and elsewhere, The Kill Chain offers hope and, ultimately, insights on how America can apply advanced technologies to prevent war, deter aggression, and maintain peace.
The Killer Strain: Anthrax and a Government Exposed
by Marilyn W. ThompsonA lethal germ is unleashed in the U.S. mail. A chain of letters spreads terror from Florida to Washington, D.C., from New York to Connecticut, from the halls of Congress to the assembly lines of the U.S. Postal Service. Five people die, and ten thousand more line up for antibiotics to protect against exposure. The government, already outsmarted by the terrorist hijackers of 9/11, leaves its workers vulnerable and a diabolical killer on the loose.Based on hundreds of hours of interviews and a review of thousands of pages of government documents, The Killer Strain is the definitive account of the year in which bioterrorism became a reality in the United States. Revealing the little-known victims and unsung heroes in the anthrax debacle, investigative reporter Marilyn Thompson also examines the FBI's slow-paced investigation of the crimes and the unprecedented scientific challenges posed by the case.The Killer Strain, more than just a thrilling read, is also a clarion wake-up call. It shows how billions of dollars and a decade of elaborate bioterror dress rehearsals meant nothing in the face of a real attack -- and how we may still be at risk.
The Killer Whale Journals: Our Love and Fear of Orcas
by Hanne StragerExperience the hauntingly beautiful world of orcas, and discover the stories that unfold when humans enter oceans alongside them.When intrepid biology student Hanne Strager volunteered to be the cook on a small research vessel in Norway's Lofoten Islands, the trip inspired a decades-long journey into the lives of killer whales—and an exploration of people's complex relationships with the biggest predators on earth. The Killer Whale Journals chronicles the now internationally renowned science writer's fascinating adventures around the world, documenting Strager's personal experiences with orcas in the wild. Killer whales' incredible intelligence, long life spans, and strong family bonds lead many people to see them as kindred spirits in the sea. But not everyone feels this way—like wolves, orcas have been both beloved and vilified throughout human history. In this absorbing odyssey, Strager traces the complicated relationship between humans and killer whales, while delving into their behavior, biology, and ecology. She brings us along in her travels to the most remote corners of the world, battling the stormy Arctic seas of northern Norway with fellow biologists intent on decoding whale-song, interviewing First Nations conservationists in Vancouver, observing Inuit hunters in Greenland, and witnessing the dismantling of black market "whale jails" in the Russian wilderness of Kamchatka. Through these captivating stories, Strager introduces us to a diverse cast of characters from Inuit elders to Australian Aboriginal whalers and guides us through the world's wild waters, from fjords above the Arctic circle in Norway to the poaching-infested waters off Kamchatka. Featuring astonishing photographs from famed nature photographer and conservationist Paul Nicklen, The Killer Whale Journals reveals rare and intimate moments of connection with these fierce, brilliant predators.
The Killer of Little Shepherds
by Douglas StarrA riveting true crime story that vividly recounts the birth of modern forensics.At the end of the nineteenth century, serial murderer Joseph Vacher, known and feared as "The Killer of Little Shepherds," terrorized the French countryside. He eluded authorities for years--until he ran up against prosecutor Emile Fourquet and Dr. Alexandre Lacassagne, the era's most renowned criminologist. The two men--intelligent and bold--typified the Belle Époque, a period of immense scientific achievement and fascination with science's promise to reveal the secrets of the human condition. With high drama and stunning detail, Douglas Starr revisits Vacher's infamous crime wave, interweaving the story of how Lacassagne and his colleagues were developing forensic science as we know it. We see one of the earliest uses of criminal profiling, as Fourquet painstakingly collects eyewitness accounts and constructs a map of Vacher's crimes. We follow the tense and exciting events leading to the murderer's arrest. And we witness the twists and turns of the trial, celebrated in its day. In an attempt to disprove Vacher's defense by reason of insanity, Fourquet recruits Lacassagne, who in the previous decades had revolutionized criminal science by refining the use of blood-spatter evidence, systematizing the autopsy, and doing groundbreaking research in psychology. Lacassagne's efforts lead to a gripping courtroom denouement. The Killer of Little Shepherds is an important contribution to the history of criminal justice, impressively researched and thrillingly told.From the Hardcover edition.

The Kindness of Strangers: How a Selfish Ape Invented a New Moral Code
by Michael E. McCulloughWhy do we give a damn about strangers? Altruism is unique to the human species. It is also one of the great evolutionary puzzles, and we may be on the brink of solving it. It turns out that, over the last 12,000 years, we have become more and more altruistic. This is despite the fact that, the majority of the time, our minds are still breathtakingly indifferent to the welfare of others. In solving the enigma of generosity in a world of strangers, McCullough takes us on a sweeping history of society and science to warn that, if we are not careful, our instincts and sympathies have as much potential for harm as for good. The bad news is that we are not designed to be kind. The good news is that we can push ourselves to be kind anyway, together.
The Kindness of Strangers: How a Selfish Ape Invented a New Moral Code
by Michael E. McCulloughA sweeping psychological history of human goodness -- from the foundations of evolution to the modern political and social challenges humanity is now facing. How did humans, a species of self-centered apes, come to care about others? Since Darwin, scientists have tried to answer this question using evolutionary theory. In The Kindness of Strangers, psychologist Michael E. McCullough shows why they have failed and offers a new explanation instead. From the moment nomadic humans first settled down until the aftermath of the Second World War, our species has confronted repeated crises that we could only survive by changing our behavior. As McCullough argues, these choices weren't enabled by an evolved moral sense, but with moral invention -- driven not by evolution's dictates but by reason. Today's challenges -- climate change, mass migration, nationalism -- are some of humanity's greatest yet. In revealing how past crises shaped the foundations of human concern, The Kindness of Strangers offers clues for how we can adapt our moral thinking to survive these challenges as well.

The Kingdom Fungi: The Biology of Mushrooms, Molds, and Lichens
by Steven L. StephensonThe ubiquitous fungi are little known and vastly underappreciated. Yet, without them we wouldn’t have bread, alcohol, cheese, tofu, or the unique flavors of mushrooms, morels, and truffles. We can’t survive without fungi. The Kingdom Fungi provides a comprehensive look at the biology, structure, and morphological diversity of these necessary organisms. It sheds light on their ecologically important roles in nature, their fascinating relationships with people, plants, and animals, and their practical applications in the manufacture of food, beverages, and pharmaceuticals. The book includes information about “true” fungi, fungus-like creatures (slime molds and water molds), and a group of “composite” organisms (lichens) that are more than just fungi. Particular attention is given to examples of fungi that might be found in the home and encountered in nature. The Kingdom Fungi is a useful introductory text for naturalists, mycologists, and anyone who wants to become more familiar with, and more appreciative of, the fascinating world of fungi.
The Kingdom of Happiness: Inside Tony Hsieh's Zapponian Utopia
by Aimee GrothFearless gonzo journalism—an insider’s look at the enigmatic and successful CEO of Zappos, Tony Hsieh, and his quest to create his own version of utopia in the center of Las Vegas.In 2010 Tony Hsieh was introduced to many as a visionary modern business leader. Under Hsieh’s leadership, Zappos became the world’s largest online shoe company by championing satisfied customers and a valued workforce. After his company was purchased by Amazon, even as he continued as its CEO, Hsieh engaged his energies and considerable fortune toward a much larger goal: building a new and more socially conscious Silicon Valley in the heart of downtown Las Vegas, all within his five-year plan. Hsieh challenged business and technology journalist Aimee Groth to uproot her life and participate in his social engineering experiment. Beginning with couch surfing, moving to a Downtown Project crash pad, and then living in Zappos corporate housing above the Gold Spike bar, Groth had a front-row view of Hsieh’s efforts to build his ideal society. With interviews from insiders on all ends of the Zappos spectrum—like the “broken dolls” who gravitate toward Hsieh’s almost cultlike personality and make up some of his inner circle, to the Zapponians who live and work on campus, to players in the top echelon of Silicon Valley—Groth offers a unique view of a world few people know much about, and sheds a new light on this complex, eccentric man. The Kingdom of Happiness is the story of one man’s quest to create his own nirvana in the desert based on his exacting design and experimentation with lessons he’s gleaned not only from the incredible success of Zappos, but also from rave culture and Burning Man. Is it the business model of the future or a cautionary tale of hubris?
The Kingdom of Rarities
by Eric DinersteinWhen you look out your window, why are you so much more likely to see a robin or a sparrow than a Kirtland's warbler or a California condor? Why are some animals naturally rare and others so abundant?
