In All Fishermen Are Liars, Gierach travels around North America seeking out quintessential fishing experiences, whether it's at a busy stream or a secluded lake hidden amid snow-capped mountains. He talks about the art of fly-tying and the quest for the perfect steelhead fly ("The Nuclear Option"), about fishing in the Presidential Pools previously fished by the elder George Bush, and the importance of traveling with like-minded companions when caught in a soaking rain.

Approximately 200,000 years ago, as modern humans began to radiate out from their evolutionary birthplace in Africa, Neanderthals were already thriving in Europe - descendants of a much earlier migration of the African genus Homo. But when modern humans eventually made their way to Europe 45,000 years ago, Neanderthals suddenly vanished.

When Bronwen Dickey brought her new dog home, she saw no traces of the infamous viciousness in her affectionate, timid pit bull. Which made her wonder: How had the breed - beloved by Teddy Roosevelt, Helen Keller, and TV's Little Rascals - come to be known as a brutal fighter? Her search for answers takes her from 19th-century New York City dogfighting pits - the cruelty of which drew the attention of the recently formed ASPCA - to early 20th-century movie sets where pit bulls cavorted with Fatty Arbuckle and Buster Keaton.

Are we "noble in reason"? Perfect, in God's image? Far from it, says New York University psychologist Gary Marcus. In this lucid and revealing book, Marcus argues that the mind is not an elegantly designed organ but a "kluge", a clumsy, cobbled-together contraption. He unveils a fundamentally new way of looking at the human mind - think duct tape, not supercomputer - that sheds light on some of the most mysterious aspects of human nature.

Lives of Weeds explores the tangled history of weeds and their relationship to humans. Through eight interwoven stories, John Cardina offers a fresh perspective on how these tenacious plants came about, why they are both inevitable and essential, and how their ecological success is ensured by determined efforts to eradicate them. Linking botany, history, ecology, and evolutionary biology to the social dimensions of humanity's ancient struggle with feral flora, Cardina shows how weeds have shaped - and are shaped by - the way we live in the natural world.

What scientific concept would improve everybody's cognitive toolkit? This is the question John Brockman, publisher of Edge.org, posed to the world's most influential thinkers. Their visionary answers flow from the frontiers of psychology, philosophy, economics, physics, sociology, and more. Surprising and enlightening, these insights will revolutionize the way you think about yourself and the world.

Growing up in California, J. Craig Venter didn't appear to have much of a future. An unremarkable student, he nearly flunked out of high school. After being drafted into the army, he enlisted in the Navy and went to Vietnam, where the life-and-death struggles he encountered as a medic piqued his interest in science and medicine. After pursuing his advanced degrees, Venter quickly established himself as a brilliant and outspoken scientist.

The brain is made up of 85 billion neurons, which are connected by over 100 trillion synapses. For over a century, a diverse array of researchers have been trying to find a language that can be used to capture the essence of what these neurons do and how they communicate - and how those communications create thoughts, perceptions, and actions. The language they were looking for was mathematics, and we would not be able to understand the brain as we do today without it.

When Bernd Heinrich decided to write a memoir of his ultramarathon running experience, he realized that the preparation for the race was as important, if not more so, than the race itself. In Why We Run, Heinrich considers the flight endurance of birds, the antelope's running prowess and limitations, and the ultra-endurance of camels to understand how human physiology can or cannot replicate these adaptations. Heinrich offers an original and provocative work combining the rigors of science with the passion of running.

Zoologist Jo Wimpenny turns a critical eye to Aesop's fables to discover whether there is any scientific truth to their portrayal of the animal kingdom. She brings the tales into the twenty-first century, introducing the latest findings on the most fascinating branches of ethological research—the study of why animals do the things they do. In each chapter she interrogates a classic fable and a different topic—future planning, tool use, self-recognition, cooperation and deception—concluding with a verdict on the veracity of each fable's portrayal from a scientific perspective.

Once again, John Gierach tells the world why the pastime of fly-fishing makes so much sense—except when it doesn't. In sparkling prose, with more than a touch of humor, he recalls the joys of landing that trout he's been watching for the last hour—and then losing an even fatter one a little later. Joy and frustration mix in Gierach's latest appreciation of the fly-fishing life as he takes us from his home waters on the Front Range of the Rockies in Colorado to fishing meccas all over North America.

All social groups have ideals for behavior, even though ethics vary among different cultures and among individuals within each culture. In trying to understand why, Churchland brings together an understanding of the influences of nature and nurture. She looks to evolution to elucidate how, from birth, our brains are configured to form bonds, to cooperate, and to care. Conscience delves into scientific studies, particularly the fascinating work on twins, to deepen our understanding of whether people have a predisposition to embrace specific ethical stands.

In Storms of My Grandchildren, James Hansen - the nation's leading scientist on climate issues - speaks out for the first time with the full truth about global warming: the planet is hurtling even more rapidly than previously acknowledged to a climatic point of no return. Although Hansen was Al Gore's science adviser for the 2006 documentary An Inconvenient Truth, his recent data shows that our situation is even more dire today.

What caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

Fifty thousand years ago - merely a blip in evolutionary time - our Homo sapiens ancestors were competing for existence with several other human species, just as their precursors had done for millions of years. Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed Homo sapiens to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special.

For all the love and attention we give dogs, much of what they do remains mysterious. Just think about different behaviors you see at a dog park. We have a good understanding of what it means when dogs wag their tails, but what about when they sniff and roll on a stinky spot? What goes on in dogs' heads and hearts-and how much can we know and understand? Canine Confidential has the answers. Written by Marc Bekoff, it not only brilliantly opens up the world of dog behavior, but also helps us understand how we can make our dogs' lives the best they can possibly be.

A rich, sweeping, and compelling work of botanical history, The Cabaret of Plants explores dozens of plant species that for millennia have challenged our imaginations, awoken our wonder, and upturned our ideas about history, science, beauty, and belief. Going back to the beginnings of human history, Richard Mabey shows how flowers, trees, and plants have been central to human experience not just as sources of food and medicine but as objects of worship, actors in creation myths, and symbols of war and peace, life and death.

In his provocative new book, evolutionary biologist Jerry A. Coyne lays out in clear, dispassionate detail why the toolkit of science, based on reason and empirical study, is reliable, while that of religion - including faith, dogma, and revelation - leads to incorrect, untestable, or conflicting conclusions.

Our sense of smell - or olfaction as it is technically known - is our most enigmatic sense. It can conjure up memories, taking us back to very specific places and emotions, whilst powerful smells can induce strong feelings of hunger or nausea. In the animal kingdom smell can be used to find food, a mate, or a home; to sense danger; and to send and receive complex messages with other members of a species. Yet despite its fundamental importance in our mental life and in the existence of all animals, our scientific understanding of how smell works is limited.

We avoid boredom at all costs. It makes us feel restless and agitated. Desperate for something to do, we play games on our phones, retie our shoes, or even count ceiling tiles. And if we escape it this time, eventually it will strike again. But what if we listened to boredom instead of banishing it? Psychologists James Danckert and John Eastwood contend that boredom isn't bad for us. It's just that we do a bad job of heeding its guidance.
