People often believe that the years immediately prior to AD 1000 were, with just a few exceptions, lacking in any major cultural developments or geopolitical encounters, that the Europeans hadn’t yet reached North America, and that the farthest feat of sea travel was the Vikings’ invasion of Britain. But how, then, to explain the presence of blond-haired people in Maya temple murals at Chichén Itzá, Mexico? Could it be possible that the Vikings had found their way to the Americas during the height of the Maya empire?

We are living in a golden age in astronomy and in the search for life the universe. Over the last few decades, space exploration has shown that not only are there habitable environments within our solar system, but there are millions of exoplanets within our galaxy that could support life. We are on the cusp of breakthroughs that will revolutionize our understanding of our place in the cosmos in. In The Secret Life of the Universe, astrobiologist and the director of the Carl Sagan Center at the SETI Institute Nathalie A. Cabrol takes us to the frontiers of the search for life.

Sweating may be one of our weirdest biological functions, but it’s also one of our most vital and least understood. In The Joy of Sweat, Sarah Everts delves into its role in the body - and in human history. Everts’ entertaining investigation takes listeners around the world - from Moscow, where she participates in a dating event in which people sniff sweat in search of love, to New Jersey, where companies hire trained armpit sniffers to assess the efficacy of their anti-sweat products. Along the way, Everts traces humanity’s long quest to control sweat.

With a wealth of never-before-accessed materials, Heather Clark brings to life the brilliant Sylvia Plath, who had precocious poetic ambition and was an accomplished published writer even before she became a star at Smith College. Refusing to read Plath’s work as if her every act was a harbinger of her tragic fate, Clark considers the sociopolitical context as she thoroughly explores Plath’s world.

The encyclopedia once shaped our understanding of the world. Created by thousands of scholars and the most obsessive of editors, a good set conveyed a sense of absolute wisdom on its reader. Contributions from Albert Einstein, Sigmund Freud, Orville Wright, Alfred Hitchcock, Marie Curie and Indira Gandhi helped millions of children with their homework. Adults cleared their shelves in the belief that everything that was explainable was now effortlessly accessible in their living rooms.

The Pan-American Highway is the longest road in the world, running the length of the Western Hemisphere from Prudhoe Bay in Alaska to Tierra del Fuego in South America. Many adventurers have journeyed the highway’s distance, but the road itself still remains shrouded in mystery. Historian Eric Rutkow chronicles the full story of the highway’s long, winding path to construction, which reshaped foreign policy, cost US taxpayers a billion dollars, consumed countless lives over a 150-year period, and changed the destinies of two continents.

In the developed world, we’ve reaped the benefits of refrigeration for more than a century, but the costs are catching up with us. We’ve eroded our connection to our food and redefined what “fresh” means. More important, refrigeration is one of the leading contributors to climate change. As the developing world races to build a US-style cold chain, Twilley asks: Can we reduce our dependence on refrigeration? Should we?

Computers have changed since 1981, when Tracy Kidder memorably recorded the drama, comedy, and excitement of one company's efforts to bring a new microcomputer to market. What has not changed is the feverish pace of the high-tech industry, the go-for-broke approach to business that has caused so many computer companies to win big (or go belly up), and the cult of pursuing mind-bending technological innovations.

A sweeping history of the fortune seekers, adventurers, despots, and thieves who have ruthlessly endeavored to extract gold, diamonds, and other treasures from Africa and its people.

Are human beings immortal? Are apples conscious? Do our legal systems make assumptions about free will that are just plain wrong? Of all the terrific books on quantum physics—from Stephen Hawking to Brian Greene—the questions they never seem to satisfy are the implications of the science. We know that quantum physics is real—our phones and computers wouldn’t work if the science wasn’t right. But what does it all mean?
