At one point or another, just about everyone has heard of the dodo bird, which is almost universally described as a cuddly, whimsical creature renowned for its alleged stupidity. This prehistoric avian had been known for hundreds of years, before it was made popular around the world in Lewis Carroll’s 1865 classic Alice's Adventures in Wonderland.

A Zoo in My Luggage is the colorful, first-hand account of Gerald Durrell's six-month animal-collecting trip in British Cameroon, and his attempts to create his own zoo. Motivated by a passion for wildlife, and a desire to save endangered species from extinction, Durrell assembles a glorious panoply of exotic animals - including a female baboon called Georgina, who later runs amok in a department store; a black-eared squirrel, who tries to bury nuts in his ear; and a gentlemanly chimpanzee named Chumly, who greets him with an outstretched hand.

How did human minds become so different from those of other animals? What accounts for our capacity to understand the way the physical world works, to think ourselves into the minds of others, to gossip, read, tell stories about the past, and imagine the future? These questions are not new: they have been debated by philosophers, psychologists, anthropologists, evolutionists, and neurobiologists over the course of centuries. One explanation widely accepted today is that humans have special cognitive instincts.

For almost 40 years, How to Choose the Sex of Your Baby has been the standard reference for couples trying to increase their chances of having the son or daughter they hope for. In this new edition of their classic book, Dr. Shettles and David Rorvik provide authoritative scientific studies and compelling anecdotal evidence demonstrating that the Shettles method continues to produce results unmatched by any other method. Dozens of testimonials confirm its ease of use and rate of success.

Own an unruly horse? Thinking about purchasing a horse but don't exactly know what to expect once you do? Ever wondered what and how a horse thinks? Mark Rashid tells stories that provide horse owners and potential buyers with the best training solutions - straight from the horse's mouth. By considering the horse's point of view, he explores a variety of solutions to common training problem like head tossing, trailer loading, mounting problems, and more.

Fifty years ago, neuroscientists thought that a mature brain was fixed like a fly in amber, unable to change. Today, we know that our brains and nervous systems change throughout our lifetimes. This concept of neuroplasticity has captured the imagination of a public eager for self-improvement - and has inspired countless Internet entrepreneurs who peddle dubious "brain training" games and apps. In this book, Moheb Costandi offers a concise and engaging overview of neuroplasticity for the general listener.

What can fossilized teeth tell us about our ancient life expectancy? What can big data on fossils reveal about farming's problematic role in human evolution? How can simple geometric comparisons of skull and pelvic fossils suggest an origin to our social nature? In Close Encounters with Humankind, paleoanthropologist Sang-Hee Lee explores some of our biggest evolutionary questions from unexpected new angles. Through a series of entertaining, bite-sized chapters, we gain new perspectives into our first hominin ancestors, our first steps on two feet, and more.

We are now on the doorstep of a fourth change brought about by two technologies: AI and robotics. The Fourth Age provides extraordinary background information on how we got to this point, and how - rather than what - we should think about the topics we’ll soon all be facing: machine consciousness, automation, employment, creative computers, radical life extension, artificial life, AI ethics, the future of warfare, superintelligence, and the implications of extreme prosperity.

Written by experts and authorities in the field and professionally narrated for easy listening, this crash course is a valuable tool both during school and when preparing for the USMLE, or if you're simply interested in the subject. The audio is focused and high-yield, covering the most important topics you might expect to learn in a typical medical school Human Anatomy course. Included are both capsule and detailed explanations of critical issues and topics you must know to master the course.

Before there were mammals on land, there were dinosaurs. And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth's first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean's former top predator became its most delicious snack. Cephalopods had to step up their game.

This gripping narrative explores today's scientific pursuit of immortality, with exclusive visits inside Silicon Valley labs and interviews with the visionaries who believe we will soon crack into the aging process and cure death. We live in an age when billionaires are betting their fortunes on laboratory advances to prove aging unnecessary and death a disease that can be cured.

New hope for those suffering from conditions like depression, anxiety, bipolar disorder, addictions, PTSD, ADHD, and more. Though incidence of these conditions is skyrocketing, for the past four decades standard treatment hasn’t much changed, and success rates in treating them have barely improved, either. Meanwhile, the stigma of the “mental illness” label - damaging and devastating on its own - can often prevent sufferers from getting the help they need. Brain specialist and best-selling author Dr. Daniel Amen aims to change all that.

Acclaimed nature writer Susan Hand Shetterly opens a window into the world of this fascinating organism by providing an elegant, often poetic, look at life on the rugged shore of the Gulf of Maine. Shetterly offers a close look at the life cycle of seaweed and introduces us to the men and women who farm and harvest it - and their increasingly difficult task of protecting this critical natural resource against forces both natural and man-made.

Increasingly, cracks are appearing in the capacity of communities, ecosystems, and landscapes to provide the goods and services that sustain our planet's well-being. The response from most quarters has been for "more of the same" that created the situation in the first place: more control, more intensification, and greater efficiency. "Resilience thinking" offers a different way of understanding the world and a new approach to managing resources. It embraces human and natural systems as complex entities continually adapting through cycles of change.

The question of how and why organisms age has teased scientists for centuries. There are myriad competing theories, from the idea that ageing is a simple wear and tear process, like the rusting of a car, to the belief that ageing and death are genetically programmed and controlled. In fact, there is no clearly defined limit to life and no single, predictable program playing itself out: different things are happening within and between tissues, and each system or organ accumulates damage at its own pace, according to the kind of insults imposed on it by daily living.

In this intoxicating concoction of history, travelogue, and memoir, one of the perfume industry’s leading scouts of natural ingredients tells the story of the precious ingredients needed to make our favorite fragrances.

The idea that plants have a mind of their own has been a prominent feature of some Indigenous narratives, literary works, and philosophical discourses. Recent scientific research in the field of plant cognition similarly highlights the capacity of botanical life to discern between options and learn from prior experiences or, in other words, to think. The Mind of Plants offers an accessible account of the idea of “the plant mind” by bringing together short essays and poems on plants and their interactions with humans.

Palaeontologist Steve Brusatte weaves together the history and evolution of our mammal forebears with stories of the scientists whose fieldwork and discoveries underlie our knowledge, both of iconic mammals like the mammoths and sabre-toothed tigers of which we have all heard, and of fascinating species that few of us are aware of. For what we see today is but a very limited range of the mammals that have existed; in this fascinating and groundbreaking book, Steve Brusatte tells their—and our—story.

We humans are the inheritors of a dynasty that has reigned over the planet for nearly 66 million years, through fiery cataclysm and ice ages: the mammals. Our lineage includes saber-toothed tigers, woolly mammoths, armadillos the size of a car, cave bears three times the weight of a grizzly, clever scurriers that outlasted Tyrannosaurus rex, and even other types of humans, like Neanderthals.

In 2020, an invisible germ - a virus - wholly upended our lives. We're most familiar with the viruses that give us colds or Covid-19. But viruses also cause a vast range of other diseases, including one disorder that makes people sprout branch-like growths as if they were trees. Viruses have been a part of our lives for so long that we are actually part virus: the human genome contains more DNA from viruses than our own genes. Meanwhile, scientists are discovering viruses everywhere they look: in the soil, in the ocean, even in deep caves miles underground.
