Honey bees get all the press, but the fascinating story of North America's native bees - an endangered species essential to our ecosystems and food supplies - is just as crucial. Our Native Bees is the result of Paige Embry's yearlong quest to learn more about these forgotten, yet fundamental, creatures. Through interviews with farmers, gardeners, scientists, and bee experts, Embry explores the importance of native bees and focuses on why they play a key role in gardening and agriculture.

Bees are like oxygen: ubiquitous, essential, and, for the most part, unseen. While we might overlook them, they lie at the heart of relationships that bind the human and natural worlds. In Buzz, the beloved Thor Hanson takes us on a journey that begins 125 million years ago, when a wasp first dared to feed pollen to its young. From honeybees and bumbles to lesser-known diggers, miners, leafcutters, and masons, bees have long been central to our harvests, our mythologies, and our very existence. They've given us sweetness and light, the beauty of flowers, and as much as a third of the foodstuffs we eat. And, alarmingly, they are at risk of disappearing.

In The Genial Gene, Joan Roughgarden forcefully rejects ideas that have come to dominate the study of animal evolution. Building on her brilliant and innovative book Evolution's Rainbow, in which she challenged accepted wisdom about gender identity and sexual orientation, Roughgarden upends the notion of the selfish gene and the theory of sexual selection and develops a compelling and controversial alternative theory called social selection.

As recently as 11,000 years ago - "near time" to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age.

Who are you? It’s the most fundamental of human questions. Are you the type of person who tilts at windmills, or the one who prefers to view them from the comfort of an air-conditioned motorcoach? Our personalities are endlessly fascinating—not just to ourselves but also to our spouses, our parents, our children, our co-workers, our neighbors. As a highly social species, humans have to navigate among an astonishing variety of personalities.

In the 1830s, a young naturalist called Charles Darwin set out as part of a survey expedition on the HMS Beagle. Darwin collected fossils and different species of plants and animals, and made many detailed observations that inspired him to develop what once seemed an absolutely crazy idea - a theory that would change the world.

Smell is the most emotional and evocative of our senses: it can bring back memories faster and with more immediacy than a photograph - so why is it so little understood? Armed with a hungry curiosity and a willingness to self-experiment, author Barney Shaw goes in search of the hidden meanings of smells. Using plain words to describe what he finds, he investigates the chemistry, psychology, history and future of this underappreciated sense.

Suddenly, research findings require a paradigm shift in our view of the microbial world. The Human Microbiome Project at the National Institutes of Health is well under way, and unprecedented scientific technology now allows the censusing of trillions of microbes inside and on our bodies as well as in the places where we live, work, and play. This intriguing, up-to-the-minute book for scientists and nonscientists alike explains what researchers are discovering about the microbe world and what the implications are for modern science and medicine.

Since the birth of civilization, human beings have manipulated other life-forms. We have selectively bred plants and animals for thousands of years to maximize agricultural production and cater to our tastes in pets. The observation of the creation of artificial animal and plant variants was a key stimulant for Charles Darwin's theory of evolution. The ability to directly engineer the genomes of organisms first became possible in the 1970s, when the gene for human insulin was introduced into bacteria.

Did you know that San Diego’s Frozen Zoo is home to preserved DNA samples from over 8,000 endangered or threatened species, or that the tell-tale smell of freshly mowed grass is actually the plant’s version of a distress call? And what about Henrietta Lacks, the “immortal woman” whose cancer cells have been divided and multiplied for research purposes for over 60 years? Even if you think you have a handle on all things trivia, you're guaranteed a big surprise with Now I Know: Science.

The ocean teems with life that thrives under difficult situations in unusual environments. The Extreme Life of the Sea takes listeners to the absolute limits of the ocean world - the fastest and deepest, the hottest and oldest creatures of the oceans. It dives into the icy Arctic and boiling hydrothermal vents - and exposes the eternal darkness of the deepest undersea trenches - to show how marine life thrives against the odds. This thrilling book brings to life the sea's most extreme species, and tells their stories as characters in the drama of the oceans.

When Stephen Bodio was a young boy in the early '50s, he saw an image in National Geographic that became forever etched in his mind: It was a photograph of a Kazakh nomad, dressed in a long coat and wearing a fur hat, holding a huge tame eagle on his fist. And a lifelong fascination with Central Asia was born.

In recent years, malaria has emerged as a cause célèbre for voguish philanthropists. Bill Gates, Bono, and Laura Bush are only a few of the personalities who have lent their names - and opened their pocketbooks - in hopes of curing the disease. Still, in a time when every emergent disease inspires waves of panic, why aren’t we doing more to eradicate one of our oldest foes? And how does a parasitic disease that we’ve known how to prevent for more than a century still infect 500 million people every year, killing nearly 1 million of them?

Known as the original "Snakemaster" from his various television shows, Austin Stevens is one of the most famous herpetologists in the world. From his show Austin Stevens: Snakemaster on Animal Planet to his many appearances in the media, Stevens is known as an incredibly smart, yet incredibly insane animal lover.

The human reaction to insects is neither purely biological nor simply cultural. And no one reacts to insects with indifference. Insects frighten, disgust, and fascinate us. Jeff Lockwood explores this phenomenon through evolutionary science, human history, and contemporary psychology, as well as a debilitating bout with entomophobia in his work as an entomologist. Exploring the nature of anxiety and phobia, Lockwood explores the lively debate about how much of our fear of insects can be attributed to ancestral predisposition for our own survival and how much is learned through individual experiences.

Paul Falkowski looks "under the hood" of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built - and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.

Learn about the nature of Extinction with iMinds insightful knowledge series. Extinction means the death of a species of animal or plant. When you think of extinct species, you probably think of dinosaurs. So it may amaze you to know that 99% of all species that once lived on the earth are now extinct!

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.

In recent years, scientists have hypothesized life-forms that can only be called "weird": organisms that live off acid rather than water, microbes that thrive at temperatures and pressure levels so extreme that their cellular structures should break down, perhaps even organisms that reproduce without DNA. Some of these strange life-forms, unrelated to all life we know, might be nearby: on rock surfaces in the American southwest, hydrothermal vents on the ocean floor, or even in our own bodies. Some, stranger still, might live in Martian permafrost, swim in the dark oceans of Jupiter's moons, or survive in the exotic ices on comets.

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.
