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.

What happened to the ancient Egyptians? When their civilization fell, did the Egyptian people disappear? Or do their descendants exist to this day? What about the ancient Persians? Romans? Mayans? For years, the answers to these questions have been hidden. But no more. Nathaniel T. Jeanson, a Harvard graduate with a PhD in cell and developmental biology, has discovered a DNA-based, generation by generation family tree for global humanity. This tree uncovers the origin and fate of these ancient peoples—and connects them to peoples alive today.

With compassion and candor, leading neurosurgeon Henry Marsh reveals the fierce joy of operating, the profoundly moving triumphs, the harrowing disasters, the haunting regrets, and the moments of black humor that characterize a brain surgeon's life.

Dr. Catherine Kleier invites us to open our eyes to the phenomenal world of plant life and to the process she calls “Natura Revelata”, the joy of celebrating and learning from the secrets of nature. As Dr. Kleier shares her knowledge with contagious excitement for her subject, she emphasizes the middle ground: Instead of focusing on cell microbiology or the study of ecosystems and habitats, she stresses the basic biology, function, and the amazing adaptations of the plants we see all around us.

Everyone knows that timing is everything. But we don't know much about timing itself. Our lives are a never-ending stream of "when" decisions: when to start a business, schedule a class, get serious about a person. Yet we make those decisions based on intuition and guesswork. Timing, it's often assumed, is an art. In When: The Scientific Secrets of Perfect Timing, Pink shows that timing is really a science.

Traditionally, Americans learned in school that the ancestors of the people who inhabited the Western Hemisphere at the time of Columbus' landing had crossed the Bering Strait 12,000 years ago; existed mainly in small nomadic bands; and lived so lightly on the land that the Americas were, for all practical purposes, still a vast wilderness. But as Charles C. Mann now makes clear, archaeologists and anthropologists have spent the last 30 years proving these and many other long-held assumptions wrong.
