In 2011, a lone wolf named Slavc set out from his home territory of Slovenia on an epic journey across the Alps. Tracked by a GPS collar, he walked over a thousand miles. In Italy he bumped into a female wolf on a walkabout of her own—the only two wolves for hundreds of square miles—and when they mated, they formed the first pack to call these mountains home in over a century. Today there are more than a hundred wolves in the area, the result of their remarkable meeting.

Submersed begins with an investigation into the beguiling subculture of DIY submersible obsessives: men and women—but mostly men—who are so compelled to sink into the deep sea that they become amateur backyard submarine-builders. Matthew Gavin Frank explores the origins of the human compulsion to sink to depth, from the diving bells of Aristotle and Alexander the Great to the Confederate H. L. Hunley, which became the first submersible to sink an enemy warship before itself being sunk during the Civil War.

Charles Hood is on a boat, wearing at least two life jackets as he scans the sky for seabirds and plumbs the depths of his—and our—relationship with the vast Pacific Ocean. Winner of the Foreword INDIES Book of the Year for his collection of essays A Salad Only the Devil Would Eat: The Joys of Ugly Nature, Hood now brings his irrepressible curiosity to the lives of petrels, frigate birds, sea snakes, and flying fish.

The Citicorp Center, a fifty-nine-story skyscraper built in 1977, immediately became one of the most recognizable features on the New York City skyline with its distinctive inclined roof and oddly placed support columns. Designed by one of the top structural engineers in the field, William LeMessurier, the tower would become the crown jewel of his professional career; In essence, he created a skyscraper on stilts. The building was a modern marvel—until it was revealed that it had a one in sixteen chance of collapse.

What began as a utopian environment, where mice had sumptuous accommodations, had all the food and water they could want, and were free from disease and predators, turned into a mouse hell. Science writer and animal behaviorist Lee Alan Dugatkin introduces listeners to the work of rodent researcher John Bumpass Calhoun. Dugatkin shows how an ecologist-turned-psychologist-turned-futurist became a science rock star embedded in the culture of the 1960s and 1970s.

The groundbreaking science of how and why we talk, and how this ability impacts every area of our lives.

Hearing is the first sense we develop—a primary warning instinct hardwired into our brains. And yet, in an increasingly noisy and distracted world, most people pay very little attention to sound. In school, we teach reading and writing, but not listening. Conscious listening is rare, and, with over half the world's population now living in cities, billions of people never experience the rich and health‑enhancing sounds of the natural world. Every day, the sounds around us affect our experience and fundamentally alter our quality of life, for better or worse.

Decades after the end of World War II, the name Ravensbrück still evokes horror for those with knowledge of this infamous all-women’s concentration camp, better known since it became the setting of Martha Hall Kelly’s bestselling novel, Lilac Girls. Particularly shocking were the medical experiments performed on some of the inmates. Ravensbrück was atypical in other ways as well, not just as the only all-female German concentration camp, but because 80 percent of its inmates were political prisoners, among them a tight-knit group of women who had been active in the French Resistance.

In Forest Euphoria, Kaishian shows us this making of a scientist and introduces readers to the queerness, literal and otherwise, of all the life around us. Fungi, we learn, commonly have more than two biological sexes—and some as many as twenty-three thousand. Some intersex slugs mutually fire calcium carbonate “love darts” at each other during courtship.

An award-winning mathematician shows how we prove what’s true, and what to do when we can’t.
