Sitting can wreak havoc on your health, and not just in the form of minor aches and pains. Recent studies show that too much sitting contributes to a host of diseases—from obesity and diabetes to cancer and depression. The typical seated office worker suffers from more musculoskeletal injuries than those workers who do daily manual labor. It turns out that sitting is as much an occupational risk as is lifting heavy weights on the job. The facts are in: sitting literally shortens your life. Your chair is your enemy, and it is murdering your body.

In 1908, near Folsom, New Mexico, a cowboy discovered the remains of a herd of extinct giant bison. By examining flint points embedded in the bones, archeologists later determined that a band of humans had killed and butchered the animals 12,450 years ago. This discovery vastly expanded America's known human history but also revealed the long-standing danger Homo sapiens presented to the continent's evolutionary richness. Distinguished scholar Dan Flores's ambitious history chronicles the epoch in which humans and animals have coexisted in the "wild new world" of North America.

In 1637, one Dutchman paid as much for a single tulip bulb as the going price of a town house in Amsterdam. Three and a half centuries later, Amsterdam is once again the mecca for people who care passionately about one particular plant—though this time the obsessions revolves around the intoxicating effects of marijuana rather than the visual beauty of the tulip. How could flowers, of all things, become such objects of desire that they can drive men to financial ruin?

From the United States Memory Championship to deep within the author's own mind, this is an electrifying work of journalism that reminds us that, in every way that matters, we are the sum of our memories.

"What should we have for dinner?" To one degree or another, this simple question assails any creature faced with a wide choice of things to eat. Anthropologists call it the omnivore's dilemma. Choosing from among the countless potential foods nature offers, humans have had to learn what is safe, and what isn't. Today, as America confronts what can only be described as a national eating disorder, the omnivore's dilemma has returned with an atavistic vengeance.

In Dumb Luck and the Kindness of Strangers, Gierach looks back to the long-ago day when he bought his first resident fishing license in Colorado, where the fishing season never ends, and just knew he was in the right place. And he succinctly sums up part of the appeal of his sport when he writes that it is "[A]n acquired taste that reintroduces the chaos of uncertainty back into our well-regulated lives".

Most of us have heard of black holes and supernovas, galaxies and the big bang. But few of us understand more than the bare facts about the universe we call home. What is really out there? How did it all begin? Jo Dunkley begins in Earth's neighborhood, explaining the nature of the solar system, the stars in our night sky, and the Milky Way. She then moves out past nearby galaxies - and back in time - to the horizon of the observable universe, which contains over a hundred billion galaxies, each with billions of stars, many orbited by planets, some of which may host life.

In the winter of 1952, New England was battered by the most brutal nor’easter in years. As the weather wreaked havoc on land, the freezing Atlantic became a wind-whipped zone of peril, setting the stage for one of the most heroic rescue stories ever lived. On February 18, while the storm raged, two oil tankers, the Pendleton and the Fort Mercer, were in the same horrifying predicament. Built with “dirty steel,” and not prepared to withstand such ferocious seas, both tankers split in two, leaving the dozens of men on board utterly at the Atlantic’s mercy.

Napoleon's Buttons is the fascinating account of 17 groups of molecules that have greatly influenced the course of history. These molecules provided the impetus for early exploration, and made possible the voyages of discovery that ensued. The molecules resulted in grand feats of engineering and spurred advances in medicine and law; they determined what we now eat, drink, and wear. A change as small as the position of an atom can lead to enormous alterations in the properties of a substance.

Know how to navigate, don’t worry about the destination, and stay alert. These are just a few of the strategies that contribute to both successful lion tracking and a life of fulfillment.

After Lawrence’s death, Françoise faced the daunting responsibility of running Thula Thula without him. Poachers attacked their rhinos, their security team wouldn’t take orders from a woman, and the authorities were threatening to cull their beloved elephant family. On top of that, the herd’s feisty new matriarch, Frankie, didn’t like her.

Already internationally acclaimed for his elegant, lucid writing on the most challenging notions in modern physics, Sean Carroll is emerging as one of the greatest humanist thinkers of his generation as he brings his extraordinary intellect to bear not only on the Higgs boson and extra dimensions but now also on our deepest personal questions. Where are we? Who are we? Are our emotions, our beliefs, and our hopes and dreams ultimately meaningless out there in the void?
