Every great drink starts with a plant. Sake began with a grain of rice. Scotch emerged from barley. Gin was born from a conifer shrub when medieval physicians boiled juniper berries with wine to treat stomach pain. The Drunken Botanist uncovers the surprising botanical history and fascinating science and chemistry of over 150 plants, flowers, trees, and fruits (and even a few fungi).

How much control do we have over love? Much less than we like to think. All that mystery, all that poetry, all those complex behaviors surrounding human bonding leading to the most life-changing decisions we’ll ever make, are unconsciously driven by a few molecules in our brains.

Like Solomon with his magic ring, famed Austrian ethologist Konrad Lorenz was a gifted student of the animal world. King Solomon's Ring, which brought him worldwide recognition, is a delightful collection of observations and insights into the lives of our furry and feathered friends, from our familiar furry companions to water shrews and jackdaws. A must listen for any animal lover.

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.

Sex, Time, and Power offers a tantalizing answer to an age-old question: Why did big-brained Homo sapiens suddenly emerge some 150,000 years ago? The key, according to Shlain, is female sexuality. Drawing on an awesome breadth of research, he shows how, long ago, the narrowness of the newly bipedal human female's pelvis and the increasing size of infants' heads precipitated a crisis for the species. Natural selection allowed for reconfiguration of hormonal cycles, entraining women with the periodicity of the moon - and imbuing women with the concept of time.

Spectacular fossil finds make today's headlines; new technology unlocks secrets of skeletons unearthed 100 years ago. Still, evolution is often poorly represented by the media and misunderstood by the public. A potent antidote to pseudoscience, Written in Stone is an engrossing history of evolutionary discovery for anyone who has marveled at the variety and richness of life.

Gavin has been a wildlife photographer for over 30 years. During that time he's lurked in the shadows of some of the world's remotest places in order to capture footage of the animal kingdom's finest: prides of lions, silverback gorillas, capuchin monkeys, brown bears, grey whales, penguins, mosquitoes - you name it he's filmed it.

Humans are a puzzling species. On the one hand, we struggle to survive on our own in the wild, often failing to overcome even basic challenges, like obtaining food, building shelters, or avoiding predators. On the other hand, human groups have produced ingenious technologies, sophisticated languages, and complex institutions that have permitted us to successfully expand into a vast range of diverse environments. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals?

In the early 19th century passenger pigeons accounted for 25 to 40 percent of North America’s birds, traveling in flocks so massive as to block out the sun for hours. Although adults weighed only twelve ounces, they nested and roosted in the millions, destroying large oaks as if hit by hurricanes. Their favorite foods were the seeds and nuts of beech, chestnuts, and other forest trees, but they also raided farmers’ buckwheat, wheat, corn, and rye crops.

In the late 1940s, a small pack of wolves crossed the ice of Lake Superior to the island wilderness of Isle Royale, creating a perfect "laboratory" for a long-term study of predators and prey. As the wolves hunted and killed the island's moose, a young graduate student named Dave Mech began research that would unlock the mystery of one of nature's most revered (and reviled) animals - and eventually became an internationally renowned and respected wolf expert. This is the story of those early years.

Brain fog is not a diagnosis in itself, but a sign that things aren't right in your body. In Beating Brain Fog, neuroscientist Dr Sabina Brennan guides us through the science to show how our brains work, and why we might experience confusion and anxiety. She offers tools to help you identify your own cognitive profile, determining the causes of your specific symptoms, and explains the simple strategies that can help you feel like yourself again.

Short, sassy, and bold, Mean Genes reveals that our struggles for self-improvement are, in fact, battles against our own genes - genes that helped our distant ancestors flourish, but are selfish and out of place in the modern world.

WASPs finally get their due in this stimulating history by one of the world's leading geneticists. Saxons, Vikings, and Celts is the most illuminating book yet to be written about the genetic history of Britain and Ireland. Through a systematic, ten-year DNA survey of more than 10,000 volunteers, Bryan Sykes has traced the true genetic makeup of British Islanders and their descendants.

Are stars like Usain Bolt, Michael Phelps, and Serena Williams genetic freaks put on Earth to dominate their respective sports? Or are they simply normal people who overcame their biological limits through sheer force of will and obsessive training? In this controversial and engaging exploration of athletic success, Sports Illustrated senior writer David Epstein tackles the great nature vs. nurture debate and traces how far science has come in solving this great riddle.

Training as an RAF pilot in the smoke and bustle of wartime London is a far cry from James Herriot’s day job as a country vet in the Yorkshire Dales. And whilst he is keen to serve King and country, James cannot help but miss his life in Darrowby – despite frequent arguments between his colleagues Siegfried and Tristan, bad-tempered cattle, opinionated farmers and the continuing saga of Cedric the flatulent dog. But most of all he misses his wife Helen; pregnant with their first child.

A leading brain scientist's look at the neurobiology of pleasure-and how pleasures can become addictions. Whether eating, taking drugs, engaging in sex, or doing good deeds, the pursuit of pleasure is a central drive of the human animal. In The Compass of Pleasure Johns Hopkins neuroscientist David J. Linden explains how pleasure affects us at the most fundamental level: in our brain.

Written with the same heartwarming sentiment that made the memoir Marley & Me a runaway best seller, biologist and owl expert Stacey O'Brien chronicles her rescue of an adorable, abandoned baby barn owl - and their astonishing and unprecedented 19-year life together.

A lo largo del último siglo, la humanidad ha logrado lo imposible frenando la hambruna, la peste y la guerra. Por primera vez en la historia, más personas mueren por obesidad que por pasar hambre y hay más probabilidades de quitarse la vida que de morir en un conflicto bélico o un atentado terrorista.

How much do you know about the meat on your dinner plate? Journalist Christopher Leonard spent more than a decade covering the country's biggest meat companies, including four years as the national agribusiness reporter for the Associated Press. Now he delivers the first comprehensive look inside the industrial meat system, exposing how a handful of companies executed an audacious corporate takeover of the nation's meat supply.

Metabolism, behavior, sleep, mood swings, the immune system, fighting, fleeing, puberty, and sex: these are just a few of the things our bodies control with hormones. Armed with a healthy dose of wit and curiosity, Randi Hutter Epstein takes us on a journey through the unusual history of these potent chemicals and their discovery, from the London laboratory where the concept of hormones was identified to a basement filled with jarred brains to a canine sex lab.
