Most of the 25,000 genes we possess are the same for all of us. Compatibility genes are those that vary most from person to person and give each of us a unique molecular signature. These genes determine both the extent to which we are susceptible to a vast range of illnesses and the different ways each of us fights disease.

It's the ultimate technology: nanotechnology - the attempt to build ordinary objects from the atoms up, molecule by molecule. So named because its building blocks are the smallest pieces of matter, nanotechnology will give us complete control over the structure of matter, allowing us to build any substance or structure permitted by the Laws of Nature. Placing atoms as if they were bricks, nano-machines could turn grass clippings into prime sirloins - directly, without cows.

From ancient empires to modern economics, veteran journalist Andrew Lawler delivers a sweeping history of the animal that has been most crucial to the spread of civilization across the globe: the chicken. Queen Victoria was obsessed with it. Socrates' last words were about it. Charles Darwin and Louis Pasteur made their scientific breakthroughs using it. Catholic popes, African shamans, Chinese philosophers, and Muslim mystics praised it.

As at home with Galileo and his daughter in Florence as he is with Diderot in Enlightenment France, William and Alice James in fin-de-siècle Boston, or the latest research on the genome, Gerald Weissmann distills the lessons of history to guide us through our troubled age. His message is clear: "Experimental science is our defense-perhaps our best defense-against humbug and the Endarkenment."

As historian Mark Essig reveals in Lesser Beasts, swine have such a bad reputation for precisely the same reasons they are so valuable as a source of food: they are intelligent, self-sufficient, and omnivorous. What's more, he argues, we ignore our historic partnership with these astonishing animals at our peril.

In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history - and our part in it - is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history.

Why a unicycle? Why a cross-country trip? Why leave a prominent New York magazine and return to the simple life in Kentucky? Reminiscent of classic literary travelogues, Mark Schimmoeller's Slowspoke: A Unicyclist's Guide to America takes listeners on an inward, emotional journey as he inches across landscapes and communities from North Carolina to Arizona. Schimmoeller became inspired by his unicycle as an adolescent.

Since moving west over a decade ago, Tom Groneberg has worked with horses as a trail guide, as a ranch hand, and as the manager of his own ranch in Montana, but he has never owned a really good horse. Until, on an autumn night, in a warm barn under a blanket of snow, Blue is born. Soon, he will belong to Tom Groneberg. "If I had a good horse," writes Tom, "I could give it my life. I could ride it for years. We could grow old together." So begins this unique American love story about a man and his horse.

Here, for the first time, is a collection of short speeches by the charismatic doctor and social activist Paul Farmer. One of the most passionate and influential voices for global health equity and social justice, Farmer encourages young people to tackle the greatest challenges of our times. Engaging, often humorous, and always inspiring, these speeches bring to light the brilliance and force of Farmer's vision in a single, accessible volume.

Imagine raising an orphaned bear cub, carefully reintroducing her to the wild, then being welcomed back, almost daily, to observe her wild world for more than 17 years. Imagine visiting her in her feeding spots, watching her with her mates and her young, peering into her den, and, over time, observing the lives of all the other wild bears in her territory and surrounding ones. That is what happened to Ben Kilham.

Eye of the Albatross takes us soaring to locales where whales, sea turtles, penguins, and shearwaters flourish in their own quotidian rhythms. Carl Safina’s guide and inspiration is an albatross he calls Amelia, whose life and far-flung flights he describes in fascinating detail. Interwoven with recollections of whalers and famous explorers, Eye of the Albatross probes the unmistakable environmental impact of the encounters between man and marine life.

Feathers are an evolutionary marvel: Aerodynamic, insulating, beguiling. They date back more than 100 million years. Yet their story has never been fully told. In Feathers, biologist Thor Hanson details a sweeping natural history, as feathers have been used to fly, protect, attract, and adorn through time and place. Applying the research of paleontologists, ornithologists, biologists, engineers, and even art historians, Hanson asks: What are feathers? How did they evolve? What do they mean to us?

An extraterrestrial colony, in some form, may already exist, just awaiting discovery. But the greatest impediment to such an important scientific discovery may not be technological, but political. No scientific endeavor can be launched without a budget, and matters of money are within the arena of politicians. Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities.

The hunt for the origin of the AIDS virus began over 20 years ago. It was a journey that went around the world and involved painstaking research to unravel how, when, and where the virus first infected humans. Dorothy H. Crawford traces the story back to the remote rain forests of Africa - home to the primates that carry the ancestral virus - and reveals how HIV-1 first jumped from chimpanzees to humans in rural southeast Cameroon. Examining how this happened, and how it then travelled back to Colonial west central Africa where it eventually exploded as a pandemic, she asks why and how it was able to spread so widely.

In the summer of 2004, veterinarian Melanie Butera received an unexpected patient: a three-day-old blind, dying fawn she called Dillie. Melanie doubted the deer would survive, but with the help of her husband, Steve, she miraculously nursed Dillie back to health. The tenacious deer quickly became a member of the family, running around the house with the dog, the cat, and the people and enjoying all of the perks, including her own bedroom, plates of her favorite linguini, and swims in the family's pool.

There is a human genetic fluke that is surprisingly common, due to a change in a key pair of chromosomes. In the normal condition the two look the same, but in this disorder one is malformed and shrunken beyond recognition. The result is a shortened life span, higher mortality at all ages, an inability to reproduce, premature hair loss, and brain defects variously resulting in attention deficit, hyperactivity, conduct disorder, hypersexuality, and an enormous excess of both outward and self-directed aggression. It is called maleness.

While birding literature is filled with tales of expert observers spotting rare species in exotic locales, John Yow reminds us that the most fascinating birds can be the ones perched right outside our windows. In thirty-five engaging and sometimes irreverent vignettes, Yow reveals the fascinating lives of the birds we see nearly every day. Following the seasons, he covers forty-two species, discussing the improbable, unusual, and comical aspects of his subjects' lives.

We have long fantasized about finding life on planets other than our own. Yet even as we become aware of the vast expanses beyond our solar system, it remains clear that Earth is exceptional. The question is: Why? In Lucky Planet, astrobiologist David Waltham argues that Earth’s climate stability is what makes it uniquely able to support life, and it is nothing short of luck that made such conditions possible. The four-billion-year stretch of good weather that our planet has experienced is statistically so unlikely that chances are slim that we will ever encounter intelligent extraterrestrial others.

While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of other animals. For instance: the male garden spider spontaneously dies after mating with a female more than fifty times his size. Female cichlids must guard their eggs and larvae--even from the hungry appetites of their own partners. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist?

Survival of the fittest or survival of the nicest? Since the dawn of time man has contemplated the mystery of altruism, but it was Darwin who posed the question most starkly. From the selfless ant to the stinging bee to the man laying down his life for a stranger, evolution has yielded a goodness that in theory should never be. Set against the sweeping tale of 150 years of scientific attempts to explain kindness, The Price of Altruism tells for the first time the moving story of the eccentric American genius George Price (1922-1975), as he strives to answer evolution's greatest riddle.
