    Putting people into places and situations unprecedented in history is stirred the imagination while the human experience was expanding and redefining. Yet, space exploration compels humans to confront a hostile environment of cosmic radiations, radical changes in the gravity and magnetic fields, as well as social isolation. Therefore, any space traveller is submitted to relevant health-related threats. In the twenty-first century, human space flight is poised to continue, but it will enjoy the ongoing developments in science and technology. It will become more networked, more global, and more oriented toward primary goals. A novel international human space flight policy could help achieve these objectives by clarifying the rationale, the ethics of acceptable risk, the role of remote presence, and the need for balance between funding and ambition to justify the risk of human lives. In order to address such a challenge, a preliminary careful survey of the available scientific data is mandatory to set forth adequate countermeasures. Envisaged solutions should provide a sound and technically feasible approach for counteracting microgravity and cosmic rays effects, which represent the main health risk for space crews. This objective must necessarily be sustained by national/international space agencies, which would coordinate their common efforts into a defined international spaceflight program.

    . .Who wants to keep bees? And why? For the answers, Master Beekeeper Frank Mortimer invites readers on an eye-opening journey into the secret world of bees, and the singular world of his fellow bee-keepers. There's the Badger, who introduces Frank to the world of bees; Rusty, a one-eyed septuagenarian bee sting therapist certain that honey will be the currency of the future after the governments fail; Scooby the "dude" who gets a meditative high off the awesome vibes of his psychedelia-painted hives; and the Berserker, a honeybee hitman who teaches Frank a rafter-raising lesson in staving off the harmful influences of an evil queen: "Squash her, mash her, kill, kill, kill!"Frank also crosses paths with those he calls the Surgeons (precise and protected), the Cowboys (improvisational and unguarded) and the Poseurs, ex-corporate cogs, YouTube-informed and ill-prepared for the stinging reality of their new lives. In connecting with this club of disparate but kindred spirits, Frank discovers the centuries-old history of the trade; the practicality of maintaining it; what bees see, think, and feel (emotionless but sometimes a little defensive); how they talk to each other and socialize; and what can be done to combat their biggest threats, both human (anti-apiarist extremists) and mite (the Varroa Destructor).With a swarm of offbeat characters and fascinating facts (did that bee just waggle or festoon?), Frank the Bee Man delivers an informative, funny, and galvanizing book about the symbiotic relationship between flower and bee, and bee and the beekeepers who are determined to protect the existence of one of the most beguiling and invaluable creatures on earth.

    They are capable of incredibly complex behavior, even with brains often the size of a poppy seed. How do they accomplish feats that look like human activity— personality, language, childcare—with completely different pathways from our own? What is going on inside the mind of those ants that march like boot-camp graduates across your kitchen floor? How does the lead ant know exactly where to take her colony, to that one bread crumb that your nightly sweep missed? Can insects be taught new skills as easily as your new puppy? Sex on Six Legs is a startling and exciting book that provides answers to these questions and many more. With the humor of Olivia Judson’s Dr. Tatiana’s Sex Advice to All Creation, Zuk not only examines the bedroom lives of creepy crawlies but also calls into question some of our own longheld assumptions about learning, the nature of personality, and what our own large brains might be for.

    When hearing those words just a couple of years back, people used to say: It’s a scam, financial bubble IThere is no point in investing, the price is too low INo country will ever recognize cryptocurrency IIt’s an obvious pyramid scheme IIt’s a sort of amusement for nerds IIt's not serious, it will collapse in a couple of years. Until recently, cryptocurrency had been viewed as a sort of amusement for a handful of the chosen who bought and sold something and believed that a new currency would make a hit one day! You surely were also among those people who did not take Bitcoin and cryptocurrency seriously, but the current events gag even the biggest skeptics. Current Bitcoin price is 6,644$* The price of the most popular cryptocurrency repeatedly breaks all the unthinkable records. Capitalization is about $120 billion World recognition The world's largest economies – India and Japan – recognized Bitcoin as the official currency. The US authorities recognized cryptocurrency as the asset. And this is just the beginning. Mining on an industrial scale The cryptocurrency market is extremely fast-changing, and it is almost impossible to monitor the situation and make the right decisions on your own. Most people have no proper experience, time and money for that. My book gives basic yet quite extensive information for those people who do not chase a rainbow but want to build a long-term profitable business in one of the cryptocurrency areas: from mining to investing. So, this book is not about: Illegal ways of making money Praising cryptocurrency and urging you to invest in it to the last penny Fraud techniques and making a fast buck Boring and pointless theory Ways to earn millions without investments and risks This book will help you get to learn the following: Which way of making money in cryptocurrency market suits you best. Where should you start if you have just $500. What information about cryptocurrency the experts withhold (Take the rose-colored glasses off!). How to elaborate a personal strategy, set up your own cryptocurrency business and earn your first $3,000-10,000 as early as 2018. I can also guarantee that you: Puzzle out the main present-day currency trend even if you are clueless about economics, finance and technology. Understand whether you really want to invest in cryptocurrency (perhaps, this type of business doesn’t suit you at all and you will save your time) Get to learn how to check the risks and not to invest in the first available currency Having considered my experience, protect yourself from possible failures and pouring money down the drain which will inevitably happen if you go it blind.

    The fastest-growing segment of the population, those beyond the age of fifty, are no longer content to simply cope with the losses of age. Mental acuity and vitality are becoming a life-long pursuit. Now, the science of the mind is catching up with the Baby Boom generation. In this landmark book, renowned psychiatrist Gene Cohen challenges the long-held belief that our brain power inevitably declines as we age, and shows that there are actually positive changes taking place in our minds. Based on the latest studies of the brain, as well as moving stories of men and women in the second half of life, The Mature Mind reveals for the first time how we can continue to grow and flourish. Cohen's groundbreaking theory-the first to elaborate on the psychology of later life-describes how the mind gives us "inner pushes" and creates new opportunities for positive change throughout adult life. He shows how we can jump-start that growth at any age and under any circumstances, fine-tuning as we go, actively building brain reserves and new possibilities. The Mature Mind offers a profoundly different and intriguing look at ourselves, challenging old assumptions, raising bold new questions, and providing exciting answers grounded in science and the realities of everyday life.

    It’s a decision Huck’s creator already had made, albeit for somewhat different reasons, a quarter of a century earlier. He wasn’t even Mark Twain then, but as Huck might have said, “That ain’t no matter.” With the Civil War spreading across his native Missouri, twenty-five-year-old Samuel Clemens, suddenly out of work as a Mississippi riverboat pilot, gladly accepted his brother Orion’s offer to join him in Nevada Territory, far from the crimsoned battlefields of war.A rollicking, hilarious stagecoach journey across the Great Plains and over the Rocky Mountains was just the beginning of a nearly six-year-long odyssey that took Samuel Clemens from St. Joseph, Missouri, to Hawaii, with lengthy stopovers in Virginia City, Nevada, and San Francisco. By the time it was over, he would find himself reborn as Mark Twain, America’s best-loved, most influential writer. The “trouble,” as he famously promised, had begun.With a pitch-perfect blend of appreciative humor and critical authority, acclaimed literary biographer Roy Morris, Jr., sheds new light on this crucial but still largely unexamined period in Mark Twain’s life. Morris carefully sorts fact from fiction—never an easy task when dealing with Twain—to tell the story of a young genius finding his voice in the ramshackle mining camps, boomtowns, and newspaper offices of the wild and woolly West, while the Civil War rages half a continent away.With the frequent help of Twain’s own words, Morris follows his subject on a winding journey of selfdiscovery filled with high adventure and low comedy, as Clemens/Twain dodges Indians and gunfighters, receives marriage advice from Brigham Young, burns down a mountain with a frying pan, gets claim-jumped by rival miners, narrowly avoids fighting a duel, hikes across the floor of an active volcano, becomes one of the first white men to try the ancient Hawaiian sport of surfing, and writes his first great literary success, “The Celebrated Jumping Frog of Calaveras County.”Lighting Out for the Territory is a fascinating, even inspiring, account of how an unemployed riverboat pilot, would-be Confederate guerrilla, failed prospector, neophyte newspaper reporter, and parttime San Francisco aesthete reinvented himself as America’s most famous and beloved writer. It’s a good story, and mostly true—with some stretchers thrown in for good measure.

    With personal narrative by one of the participants of fell-running—a sport that little is known about, but one that also boasts mass-participation—this fascinating account of arduous circuits, week-long marathons, and pounding the mountainous trails of the Lake District and Snowdonia is a unique and compelling account of stamina and courage that stretches the limits of belief.

    The lone survivor comes to stand for the entirety of a lost species.
