April 25, 1986 in Chernobyl was a turning point in world history. The disaster not only changed the world’s perception of nuclear power and the science that spawned it, but also our understanding of the planet’s delicate ecology. With the images of the abandoned homes and playgrounds beyond the barbed wire of the 30-kilometer Exclusion Zone, the rusting graveyards of contaminated trucks and helicopters, the farmland lashed with black rain, the event fixed for all time the notion of radiation as an invisible killer.

We've all seen the happiness on the face of a child while playing in the school yard. Or the blissful abandon of a golden retriever racing across a lawn. This is the joy of play. By definition, play is purposeless, all-consuming, and fun. But as Dr. Stuart Brown illustrates, play is anything but trivial. It is a biological drive as integral to our health as sleep or nutrition. We are designed by nature to flourish through play.

When we think of fungi, we likely think of mushrooms. But mushrooms are only fruiting bodies, analogous to apples on a tree. Most fungi live out of sight, yet make up a massively diverse kingdom of organisms that supports and sustains nearly all living systems. Fungi provide a key to understanding the planet on which we live, and the ways we think, feel, and behave.

Borderline personality disorder, autism, narcissism, psychosis, Asperger's: All of these syndromes have one thing in common---lack of empathy. In some cases, this absence can be dangerous, but in others it can simply mean a different way of seeing the world. In The Science of Evil, Simon Baron-Cohen, an award-winning British researcher who has investigated psychology and autism for decades, develops a new brain-based theory of human cruelty.

Françoise Malby-Anthony is the owner of a game reserve in South Africa with a remarkable family of elephants whose adventures have touched hearts around the world. The herd’s feisty matriarch Frankie knows who’s in charge at Thula Thula, and it’s not Francoise. But when Frankie becomes ill, and the authorities threaten to remove or cull some of the herd if the reserve doesn’t expand, Françoise is in a race against time to save her beloved elephants. The joys and challenges of a life dedicated to conservation are vividly described in The Elephants of Thula Thula.

Global warming is one of the greatest dangers mankind faces today. Even as temperatures increase, sea levels rise, and natural disasters escalate, our current environmental crisis feels difficult to predict and understand. But climate change and its effects on us are not new. In a bold narrative that spans centuries and continents, Peter Frankopan argues that nature has always played a fundamental role in the writing of history.

Although eugenics is now widely discredited, some groups and individuals claim a new scientific basis for old racist assumptions. Pondering the continuing influence of racist research and thought, despite all evidence to the contrary, Robert Wald Sussman explains why - when it comes to race - too many people still mistake bigotry for science.

An "elegant", "engrossing" (Carol Tavris, Wall Street Journal) examination of what we think we know about the brain and why - despite technological advances - the workings of our most essential organ remain a mystery.

De Waal reviews the rise and fall of the mechanistic view of animals and opens our minds to the idea that animal minds are far more intricate and complex than we have assumed. De Waal's landmark work will convince you to rethink everything you thought you knew about animal - and human - intelligence.

Stress is our internal response to an experience that our brain perceives as threatening or challenging. Trauma is our response to an experience in which we feel powerless or lacking agency. Until now, researchers have treated these conditions as different, but they actually lie along a continuum. Dr. Elizabeth Stanley explains the significance of this continuum, how it affects our resilience in the face of challenge, and why an event that's stressful for one person can be traumatizing for another.

But Intervention Earth is about more than technological mega-projects.

From the masters of storytelling-meets-science, Patient Zero tells the long and fascinating history of disease outbreaks—how they start, how they spread, the science that lets us understand them, and how we race to destroy them before they destroy us. Written in the authors’ lively style, chapters include gripping medical stories about a particular disease or virus—smallpox, Bubonic plague, polio, HIV—that combine “Patient Zero” narratives, or the human stories behind outbreaks, with historical examinations of missteps, milestones, scientific theories, and more.

Ants number in the ten quadrillions, and they have been here since the Jurassic era. Inside an anthill, you'll find high drama worthy of a royal court; and between colonies, high-stakes geopolitical intrigue is afoot. Just like us, ants grow crops, raise livestock, tend their young and infirm, and make vaccines. And, just like us, ants have a dark side: They wage war, despoil environments, and enslave rivals - but also rebel against their oppressors.

Before John Deere, Ford, and International Harvester became icons of American business, they were competitors in a forgotten battle for the farm. By the turn of the 20th century, four million people had left rural America and moved to cities. With the tractor, a shrinking farm population could still feed a growing world. Tractor Wars is the untold story of industry stalwarts and disruptors, inventors, and administrators racing to invent modern agriculture - a power farming revolution that would usher in a whole new world.

Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to find meaning in the face of this vast expanse. Greene takes us on a journey from the big bang to the end of time, exploring how lasting structures formed, how life and mind emerged, and how we grapple with our existence through narrative, myth, religion, creative expression, science, the quest for truth, and a deep longing for the eternal.

Trish O’Kane is an accidental ornithologist. In her nearly two decades writing about justice as an investigative journalist, she'd never paid attention to nature. But then Hurricane Katrina destroyed her New Orleans home, sending her into an emotional tailspin. Enter a scrappy cast of feathered characters—first a cardinal, urban parrots, and sparrows, then a catbird, owls, a bittern, and a woodcock—that cheered her up and showed her a new path. Inspired, O'Kane moved to Madison, Wisconsin, to pursue an environmental studies PhD.
