Mastering the fat hormone leptin is the single most important factor in preventing obesity, diabetes, and heart disease. The Leptin Diet contains five simple lifestyle guidelines to get the hormone leptin into balance for permanent weight loss, increased energy, and optimum health. What is Leptin? Fat cells produce the powerful hormone leptin, a primary force instructing metabolism, weight loss, and hormone balance. Leptin communicates directly to your brain, telling the brain how much fat is in storage. It controls appetite, energy, and metabolic rate. Leptin problems are the primary reason for food cravings, overeating, faulty metabolism, the obsession with food, and heart disease. Read The Leptin Diet and notice the difference!

    From the world’s most painful hornet, to the flies that transmit deadly diseases, to millipedes that stop traffic, to the “bookworms” that devour libraries, to the Japanese beetles munching on your roses, Wicked Bugs delves into the extraordinary powers of many-legged creatures. With wit, style, and exacting research, Stewart has uncovered the most terrifying and titillating stories of bugs gone wild. It’s an A to Z of insect enemies, interspersed with sections that explore bugs with kinky sex lives (“She’s Just Not That Into You”), creatures lurking in the cupboard (“Fear No Weevil”), insects eating your tomatoes (“Gardener’s Dirty Dozen”), and phobias that feed our (sometimes) irrational responses to bugs (“Have No Fear”). Intricate and strangely beautiful etchings and drawings by Briony Morrow-Cribbs capture diabolical bugs of all shapes and sizes in this mixture of history, science, murder, and intrigue that begins—but doesn’t end—in your own backyard.

    When we bite into a shiny apple, listen to the resonant notes of a violin, try on the latest fashions, receive a dental implant, or get a manicure, we are mingling with the by-products of their everyday lives. Try as we might to replicate their raw material (silk, shellac, and cochineal, for instance), our artificial substitutes have proven subpar at best, and at worst toxic, ensuring our interdependence with the insect world for the foreseeable future. With illuminating demonstrations and thoughtful histories, and drawing on research in laboratory science, agriculture practices, fashion, and international cuisine, Melillo weaves a colorful world history that shows humans and insects as inextricably intertwined. He makes clear that, across time, humans have not only coexisted with these creatures, but have relied on them for, among other things, the key discoveries of modern medical science and the future of the world's food supply. Here is a fascinating appreciation of the ways in which these creatures have altered--and continue to shape--the very frameworks of our existence.

    But what were and are the true potentates of our planet? Insects, says Scott Richard Shaw—millions and millions of insect species. Starting in the shallow oceans of ancient Earth and ending in the far reaches of outer space—where, Shaw proposes, insect-like aliens may have achieved similar preeminence—Planet of the Bugs spins a sweeping account of insects’ evolution from humble arthropod ancestors into the bugs we know and love (or fear and hate) today. Leaving no stone unturned, Shaw explores how evolutionary innovations such as small body size, wings, metamorphosis, and parasitic behavior have enabled insects to disperse widely, occupy increasingly narrow niches, and survive global catastrophes in their rise to dominance. Through buggy tales by turns bizarre and comical—from caddisflies that construct portable houses or weave silken aquatic nets to trap floating debris, to parasitic wasp larvae that develop in the blood of host insects and, by storing waste products in their rear ends, are able to postpone defecation until after they emerge—he not only unearths how changes in our planet’s geology, flora, and fauna contributed to insects’ success, but also how, in return, insects came to shape terrestrial ecosystems and amplify biodiversity. Indeed, in his visits to hyperdiverse rain forests to highlight the current insect extinction crisis, Shaw reaffirms just how crucial these tiny beings are to planetary health and human survival. In this age of honeybee die-offs and bedbugs hitching rides in the spines of library books, Planet of the Bugs charms with humor, affection, and insight into the world’s six-legged creatures, revealing an essential importance that resonates across time and space.

    Now award-winning writer Carl Zimmer takes us on a fantastic voyage into the secret parasite universe we actually live in but haven't recognized. He reveals not only that parasites are the most successful life-forms on Earth, but that they triggered the development of sex, shape ecosystems, and have driven the engine of evolution. In mapping the parasite universe, Zimmer makes the astonishing observation that most species are parasites, and that almost every animal, including humans, will at one time or another become the home of a parasite. Zimmer shows how highly evolved parasites are and describes the frightening and amazing ingenuity these commando invaders use to devour their hosts from the inside and control their behavior. The sinister Sacculina carcini makes its home in an unlucky crab and proceeds to eat everything but what the crab needs to put food in its mouth, which Sacculina then consumes. When Sacculina finally reproduces, it places its young precisely where the crab would nurture its own progeny, and then has the crab nurture the foster family members. Single-celled Toxoplasma gondi has an even more insidious role, for it can invade the human brain. There it makes men distrustful and less willing to submit to social mores. Women become more outgoing and warm-hearted. Why would a parasite cause these particular personality changes? It seems Toxoplasma wants its host to be less afraid, to be more prone to danger and a violent end -- so that, in the carnage, it will be able to move on to another host. From the steamy jungles of Costa Rica to the fetid parasite heaven of rebel-held southern Sudan, Zimmer tracks the genius of parasitic life and its impact on humanity. We hosts have developed remarkable defenses against the indomitable parasite: our mighty immune system, our culturally enforced habit of keeping clean, and, perhaps most intriguingly, sex. But this is not merely a book about the evil power of parasitism and how we must defend against it. On the contrary, Zimmer concludes that humankind itself is a new kind of parasite, one that preys on the entire Earth. If we are to achieve the sophistication of the parasites on display here in vivid detail, if we are to promote the flourishing of life in all its diversity as they do, we must learn the ways nature lives with itself, the laws of Parasite Rex.

    That word is formication, and the implied sense of horror and fascination, contends Richard Conniff, is something many of us actually crave. His Spineless Wonders presents an unabashed wallow in the joy of formication. Spineless Wonders is an engaging, sophisticated, and humorous mix of natural history and human lore. Through his journalistic assignments, Richard Conniff has been in contact with invertebrates for more than twenty years - tarantulas in the upper Amazon region, dragonflies in Arizona, squid in Florida, and flies on the rim of his beer glass. Discoveries about the extraordinary habits and idiosyncrasies of the moth, the leech, the ant, and the slime eel are opening new frontiers in the exploration of our natural universe. Spineless Wonders takes us directly to these wild and wonderful outposts to observe the hazards of being around invertebrates, the bizarre adaptions that enable them to survive in the world, and also the astonishing work they do - work that enables us to survive.

    As the mosquito transformed the landscapes of civilization, humans were unwittingly required to respond to its piercing impact and universal projection of power.The mosquito has determined the fates of empires and nations, razed and crippled economies, and decided the outcome of pivotal wars, killing nearly half of humanity along the way. She (only females bite) has dispatched an estimated 52 billion people from a total of 108 billion throughout our relatively brief existence. As the greatest purveyor of extermination we have ever known, she has played a greater role in shaping our human story than any other living thing with which we share our global village.Imagine for a moment a world without deadly mosquitoes, or any mosquitoes, for that matter? Our history and the world we know, or think we know, would be completely unrecognizable.Driven by surprising insights and fast-paced storytelling, The Mosquito is the extraordinary untold story of the mosquito's reign through human history and her indelible impact on our modern world order.

    The story of a lifetime of such minute explorations, For Love of Insects celebrates the small creatures that have emerged triumphant on the planet, the beneficiaries of extraordinary evolutionary inventiveness and unparalleled reproductive capacity. Eisner tells us, but never has a reckoning been such a pleasure. Recounting exploits and discoveries in his laboratory at Cornell and in the field in Uruguay, Australia, Panama, Europe and North America, Eisner time and again demonstrates how inquiry into the survival strategies of an insect leads to clarifications beyond the expected; insects are revealed as masters of achievement, forms of life worthy of study and respect from even the most recalcitrant entomophobe. Filled with descriptions of his ingenious experiments and illustrated with photographs, this book makes readers participants in the grand adventure of discovery on a scale infinitesimally small and infinitely surprising.
