    Much like human families, tree parents live together with their children, communicate with them, and support them as they grow, sharing nutrients with those who are sick or struggling and creating an ecosystem that mitigates the impact of extremes of heat and cold for the whole group. As a result of such interactions, trees in a family or community are protected and can live to be very old. In contrast, solitary trees, like street kids, have a tough time of it and in most cases die much earlier than those in a group.Drawing on groundbreaking new discoveries, Wohlleben presents the science behind the secret and previously unknown life of trees and their communication abilities; he describes how these discoveries have informed his own practices in the forest around him. As he says, a happy forest is a healthy forest, and he believes that eco-friendly practices not only are economically sustainable but also benefit the health of our planet and the mental and physical health of all who live on Earth.

    She's the Chief of Staff at a retirement home, which doesn't sound odd on its own, but when you consider it's a retirement home for witches and other paranormals, the strange factor ratchets up.  And, with a facility full of partly senile but still powerful witches, things go hilariously awry fast. This e-book contains the first three books in the Sunnyside Retired Witches Community series. Book 1: A Bottle Full of Djinn: Zoey Rivers has a pretty great job as Head of Staff at Sunnyside Retired Witches Community. She's good at handling the magical messes that are part and parcel of providing a home for elderly (and some slightly senile) witches. But when the messes turn from slightly sloppy to hugely horrible, Zoey realizes there's more involved than just her residents. If she doesn't figure out who's causing havoc at the Home, the place might not be standing for much longer. If you love crime capers with magic, mayhem, and mystery, you'll adore Zoey Rivers and her comical crew of witch retirees. Please note: This book is a crime caper, not a murder mystery. Book 2: Loony Town: Caring for elderly witches at the retirement home in Sunnyside, California is a full-time job for Zoey Rivers. But when one of them is blitzing, causing magic to act even weirder than normal, things get…well, downright wacky. And when a local insurance agent winds up dead, some of the people Zoey is responsible for become the prime suspects. As the zaniness of the magical blips continues and things get crazier and crazier, Zoey has to work fast and try to stay one step ahead to keep her charges out of jail, figure out who is causing the chaotic blitzing so she can fix it, and also figure out who the real killer is. It’s a tough job, but she's determined to do it. The people who live at Sunnyside Retired Witches Community are counting on her. And she’s not about to let them down now. Book 3: Mummy Issues: Sunnyside Retirement Witches Community gets its fair share of visitors. Some of them like the entertainment and others enjoy volunteering. But when one of the sight-seers ends up dead, Zoey Rivers has to figure out what happened. The residents come up with a fantastic idea: Since the retirement complex seems to have more than its fair share of murders, they figure it might be a good idea to have a psychic on staff. So, Zoey hires Iris. And all the information she pulls from the ghosts of the growing list of victims points to Zoey herself. Except the clues aren't pointing to her. They're fingering someone she'd thought was long dead.Sunnyside Retirement Witches Community gets its fair share of visitors. Some of them like the entertainment and others enjoy volunteering.

    bataar bones he was impressed. The enormous skull and teeth betrayed the apex predators close relation to the storied Tyrannosaurus rex, the most famous animal that ever lived. Prokopi's obsession with fossils had begun decades earlier, when he was a Florida boy scouring for shark teeth and Ice Age remnants, and it had continued as he built a thriving business hunting, preparing, and selling specimens to avid collectors and private museums around the world. To scientists' fury and dismay, there was big money to be made in certain corners of the fossil trade. Prokopi didn't consider himself merely a businessman, though. He also thought of himself as a vital part of paleontology--as one of the lesser-known artistic links in bringing prehistoric creatures back to life--and saw nothing wrong with turning a profit in the process. Bone hunting was expensive, risky, controversial work, and he increasingly needed bigger "scores." By the time he acquired a largely complete skeleton of T. bataar and restored it in his workshop, he was highly leveraged and drawing quiet scorn from peers who worried that by bringing such a big, beautiful Mongolian dinosaur to market he would tarnish the entire trade. Presenting the skeleton for sale at a major auction house in New York City, he was relieved to see the bidding start at nearly $1 million---only to fall apart when the president of Mongolia unexpectedly stepped in to question the specimen's origins and demand its return. An international custody battle ensued, shining new light on the black market for dinosaur fossils, the angst of scientists who fear for their field, and the precarious political tensions in post-Communist Mongolia. The Prokopi case, unprecedented in American jurisprudence, continues to reverberate throughout the intersecting worlds of paleontology, museums, art, and geopolitics.

    When we listen, we can notice that there are seven main lessons he encourages for people to learn. By learning and implementing these lessons and habits into your everyday life, you can increase your likelihood of achieving your goals and manifesting your dreams into reality. These habits work in both your personal life, as well as your career life, and will assist you in making the most of any opportunity. It is important to realize that you must work simultaneously on your personal and business lives to achieve success in either, because as Anthony says: “Success without fulfillment is failure.” You cannot truly succeed in one, if you are unhappy and failing within’ the other.

     Even before becoming a husband and father, safety had been Shane McDonald’s priority for most of his forty-five years. As a nuclear engineer, it’s his responsibility to keep the Sequoyah Nuclear Plant functioning at optimum levels to avoid what protesters fear most—a meltdown. But when a coronal mass ejection from the sun wipes out power across the globe, stopping a nuclear chain reaction is no longer his primary concern. Fallen World Family is all that matters when friend becomes foe—and the stakes are survival. The world has become a dangerous place for Shane McDonald and his family since the solar storm wiped out the power grid. Tensions flare when it grows clear the dire situation will be prolonged and most are ill-prepared. Even the friendly small town of his prepper mother-in-law has drawn unwanted attention as word gets around about sharing their supply stores. And strangers begin to infiltrate the once peaceful Georgia community. All Shane can think about is where his wife and son ended up in all the chaos as the hours stretch into days since they last communicated. Jodi is far too trusting a soul, her desire to help the downtrodden a dangerous commodity among desperate and increasingly hostile citizens. New World They’ll protect what’s theirs—or die trying. The McDonald clan have learned their lessons the hard way these last months. Shane and Jodi finally realize they must keep their reunited family close and protect their own above all others to survive in this new post-apocalyptic reality. The repairs on the home are complete, solar panels installed, and the now operational pump means they won’t have to continue collecting rainwater for the foreseeable future. But it’s no longer just outsiders wreaking havoc on the small Georgia town, as unprepared townsfolk learn of their hard-earned stores—and threaten to take their prepper supplies by force.

    In Sightings, a collection of essays, bird watching forms the basis for observations spiritual and soulful, witty and wise. He describes his childhood ramblings in the silence of the Tennessee wilderness as feeling distinctly more spiritualthan the hard pews of his grandmother's church. Later in life, the presumed extinction and subsequent rediscovery of the Ivory-billed Woodpecker prompts a meditation on the nature of the sacred. Blessed with moments of beauty and the insight to recognize them as such, Keen translates the marvels of nature into the language of heart and soul.

    Genetic manipulation and artificial intelligence shape an astounding destiny for our species. With these wondrous changes come unexpected new truths of heart and mind that challenge the very definition of human—and that threaten not only our existence but the universe itself as our surprising powers—both miraculous and monstrous—evolve through the centuries.

    Recent, massive blooms of billions of jellyfish have clogged power plants, decimated fisheries, and caused millions of dollars of damage. Driven by questions about how overfishing, coastal development, and climate change were contributing to a jellyfish population explosion, Juli embarked on a scientific odyssey. She traveled the globe to meet the biologists who devote their careers to jellies, hitched rides on Japanese fishing boats to see giant jellyfish in the wild, raised jellyfish in her dining room, and throughout it all marveled at the complexity of these alluring and ominous biological wonders.

    Taking as territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. To that end, he has attached himself to a host of the world’s most advanced (and often obsessed) archaeologists, anthropologists, and mathematicians, travelling to their offices, laboratories, and field camps. He has read (or tried to read) their books, pestered them with questions, apprenticed himself to their powerful minds. A Short History of Nearly Everything is the record of this quest, and it is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Science has never been more involving or entertaining.

    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.

    Simon Winchester has also fashioned an enthralling and informative informative look at the tumultuous subterranean world that produces earthquakes, the planet's most sudden and destructive force.In the early morning hours of April 18, 1906, San Francisco and a string of towns to its north-northwest and the south-southeast were overcome by an enormous shaking that was compounded by the violent shocks of an earthquake, registering 8.25 on the Richter scale. The quake resulted from a rupture in a part of the San Andreas fault, which lies underneath the earth's surface along the northern coast of California. Lasting little more than a minute, the earthquake wrecked 490 blocks, toppled a total of 25,000 buildings, broke open gas mains, cut off electric power lines throughout the Bay area, and effectively destroyed the gold rush capital that had stood there for a half century.Perhaps more significant than the tremors and rumbling, which affected a swatch of California more than 200 miles long, were the fires that took over the city for three days, leaving chaos and horror in its wake. The human tragedy included the deaths of upwards of 700 people, with more than 250,000 left homeless. It was perhaps the worst natural disaster in the history of the United States.Simon Winchester brings his inimitable storytelling abilities -- as well as his unique understanding of geology -- to this extraordinary event, exploring not only what happened in northern California in 1906 but what we have learned since about the geological underpinnings that caused the earthquake in the first place. But his achievement is even greater: he positions the quake's significance along the earth's geological timeline and shows the effect it had on the rest of twentieth-century California and American history.A Crack in the Edge of the World is the definitive account of the San Francisco earthquake. It is also a fascinating exploration of a legendary event that changed the way we look at the planet on which we live.

    This man was a freediver, and his amphibious abilities inspired Nestor to seek out the secrets of this little-known discipline. In Deep, Nestor embeds with a gang of extreme athletes and renegade researchers who are transforming not only our knowledge of the planet and its creatures, but also our understanding of the human body and mind. Along the way, he takes us from the surface to the Atlantic’s greatest depths, some 28,000 feet below sea level. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and seals who dive to depths below 2,400 feet for up to eighty minutes—deeper and longer than scientists ever thought possible. As strange as these phenomena are, they are reflections of our own species’ remarkable, and often hidden, potential—including echolocation, directional sense, and the profound physiological changes we undergo when underwater. Most illuminating of all, Nestor unlocks his own freediving skills as he communes with the pioneers who are expanding our definition of what is possible in the natural world, and in ourselves.
