In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field is horizontal gene transfer (HGT), or the movement of genes across species lines. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection - a type of HGT. In The Tangled Tree David Quammen chronicles these discoveries through the lives of the researchers who made them.

Why do we do the things we do? More than a decade in the making, this game-changing book is Robert Sapolsky's genre-shattering attempt to answer that question as fully as perhaps only he could, looking at it from every angle. Sapolsky's storytelling concept is delightful, but it also has a powerful intrinsic logic: He starts by looking at the factors that bear on a person's reaction in the precise moment a behavior occurs and then hops back in time from there in stages, ultimately ending up at the deep history of our species and its evolutionary legacy.

Who are we, and how did we get here? These are two of the most fundamental and far-reaching questions facing scientists and cosmologists alike and have rested at the center of human intellectual endeavor since its beginning. They are questions that stretch across numerous disciplines. Philosophy, theology, evolutionary biology, and mathematics are just some of the fields looking to explain the emergence of human life.

Penguin presents the unabridged, downloadable audiobook edition of World Order by Henry Kissinger, read by Nicholas Hormann. World Order is the summation of Henry Kissinger's thinking about history, strategy and statecraft. As if taking a perspective from far above the globe, it examines the great tectonic plates of history and the motivations of nations, explaining the attitudes that states and empires have taken to the rest of the world from the formation of Europe to our own times.

Scientific developments radically alter our understanding of the world. Whether it's technology, climate change, health research, or the latest revelations of neuroscience, physics, or psychology, science has, as Edge editor John Brockman says, "become a big story, if not the big story". In that spirit this new addition to Edge.org's fascinating series asks a powerful and provocative question: What do you consider the most interesting and important recent scientific news?

Most books about the history of humanity pursue either a historical or a biological approach, but Dr. Yuval Noah Harari breaks the mold with this highly original book. From examining the role evolving humans have played in the global ecosystem to charting the rise of empires, Sapiens integrates history and science to reconsider accepted narratives, connect past developments with contemporary concerns, and examine specific events within the context of larger ideas.

Most history is hierarchical: it's about emperors, presidents, prime ministers, and field marshals. It's about states, armies, and corporations. It's about orders from on high. Even history "from below" is often about trade unions and workers' parties. But what if that's simply because hierarchical institutions create the archives that historians rely on? What if we are missing the informal, less well documented social networks that are the true sources of power and drivers of change?

Improbable Destinies will change the way we think and talk about evolution. Losos' insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

Life is the most extraordinary phenomenon in the known universe; but how does it work? Even in this age of cloning and synthetic biology, the remarkable truth remains: nobody has ever made anything living entirely out of dead material. Life remains the only way to make life. Are we missing a vital ingredient in its creation? Like Richard Dawkins' The Selfish Gene, which provided a new perspective on how evolution works, Life on the Edge alters our understanding of life's dynamics.

Seventy years ago, Erwin Schrdinger posed a simple, yet profound, question: What is life?. How could the very existence of such extraordinary chemical systems be understood? This problem has puzzled biologists and physical scientists both before, and ever since. Living things are hugely complex and have unique properties, such as self-maintenance and apparently purposeful behaviour which we do not see in inert matter. So how does chemistry give rise to biology?

"Correlation does not imply causation". This mantra has been invoked by scientists for decades and has led to a virtual prohibition on causal talk. But today, that taboo is dead. The causal revolution, sparked by Judea Pearl and his colleagues, has cut through a century of confusion and placed causality - the study of cause and effect - on a firm scientific basis. 

Internationally renowned, award-winning theoretical physicist, New York Times bestselling author of A Universe from Nothing, and passionate advocate for reason, Lawrence Krauss tells the dramatic story of the discovery of the hidden world of reality - a grand poetic vision of nature - and how we find our place within it.

As science informs public policy, decision making, and so many aspects of our everyday lives, a scientifically literate society is crucial. In that spirit, Edge.org publisher and author of Know This, John Brockman, asks 206 of the world's most brilliant minds the 2017 Edge Question: What scientific term or concept ought to be more widely known?

What is human consciousness, and how is it possible? This question fascinates thinking people from poets and painters to physicists, psychologists, and philosophers. From Bacteria to Bach and Back is Daniel C. Dennett's brilliant answer, extending perspectives from his earlier work in surprising directions, exploring the deep interactions of evolution, brains, and human culture.

We’ve all had the experience of reading about a bloody war or shocking crime and asking, “What is the world coming to?” But we seldom ask, “How bad was the world in the past?” In this startling new book, the best-selling cognitive scientist Steven Pinker shows that the world of the past was much worse. In fact, we may be living in the most peaceable era in our species’ existence.
