As recently as 1990, it seemed plausible that the solar system was a unique phenomenon in our galaxy. Thanks to advances in technology and clever new uses of existing data, now we know that planetary systems and possibly even a new Earth can be found throughout galaxies near and far.

In 1942, a team at the University of Chicago achieved what no one had before: a nuclear chain reaction. At the forefront of this breakthrough stood Enrico Fermi. Straddling the ages of classical physics and quantum mechanics, equally at ease with theory and experiment, Fermi truly was the last man who knew everything - at least about physics. But he was also a complex figure who was a part of both the Italian Fascist Party and the Manhattan Project, and a less-than-ideal father and husband who nevertheless remained one of history's greatest mentors.

Railways are one of the most important inventions in modern history.

The Esperanza Fire started October 26, 2006, in the San Jacinto Mountains above the Banning Pass near Cabazon, California. It destroyed 41,000 acres and dozens of homes and cost the taxpayers $16 million dollars. But by far the highest costs of the conflagration were the lives of the five-man crew of Engine 57, the first engine crew ever killed fighting a wildland blaze. Fire and superheated gases had erupted in a freak "area ignition," sending flames racing across three-quarters of a mile in mere seconds, engulfing the crew and the house they were defending.

Balancing a broad array of archaeological, botanical, and historical evidence, Fruit from the Sands presents the fascinating story of the origins and spread of agriculture across Inner Asia and into Europe and East Asia. Through the preserved remains of plants in archaeological sites, Robert N. Spengler III identifies the regions where our most familiar crops were domesticated and follows their routes as people carried them around the world. Vividly narrated, Fruit from the Sands explores how the foods we eat have shaped the course of human history.

When Duke University gave free iPods to the freshman class in 2003, critics said they were wasting their money. Yet when the students in practically every discipline invented academic uses for the music players, suddenly the idea could be seen in a new light - as an innovative way to turn learning on its head. Using cutting-edge research on the brain, Cathy N. Davidson show how attention blindness has produced one of our society's greatest challenges.

Scientists, journalists, and politicians increasingly tell us that human impacts on climate constitute the single greatest threat facing our planet and may even bring about the extinction of our species. Yet behind these anxieties lies an older, much deeper fear about the power that climate exerts over us. The Empire of Climate traces the history of this idea and its pervasive influence over how we interpret world events and make sense of the human condition, from the rise and fall of ancient civilizations to the afflictions of the modern psyche.

4-H, the iconic rural youth program run by the U.S. Department of Agriculture, has enrolled more than 70 million Americans over the last century. As the first comprehensive history of the organization, The 4-H Harvest tracks 4-H from its origins in turn-of-the-century agricultural modernization efforts, through its role in the administration of federal programs during the New Deal and World War II, to its status as an instrument of international development in Cold War battlegrounds like Vietnam and Latin America.

From green-lifestyle mavens who endorse products on social media to natural health activists sponsored by organic food companies, the marketplace for advice about how to live life naturally is better stocked than ever. Where did the curious idea of buying one’s way to sustainability come from? In no small part, as Andrew Case shows, the answer lies in the story of entrepreneur and reformer J. I. Rodale, his son Robert Rodale, and their company, the Rodale Press.
