Biological Age

Revealed for the first time in Racing for the Bomb, Groves played a crucial and decisive role in the planning, timing, and targeting of the Hiroshima and Nagasaki missions. Norris offers new insights into the complex and controversial questions surrounding the decision to drop the bomb in Japan and Groves' actions during World War II, which had a lasting imprint on the nuclear age and the Cold War that followed.

In accessible language and with periodic references to Star Trek, motorcycle daredevils, and near-classic movies of the '80s, developmental molecular biologist John Medina explores the neurological and evolutionary factors that drive teenage behavior and can affect both achievement and engagement. Then he proposes a research-supported counterattack: a bold redesign of educational practices and learning environments to deliberately develop teens' cognitive capacity to manage their emotions, plan, prioritize, and focus.

First published more than 50 years ago, this award-winning classic brings Rachel Carson's unique vision to a new generation of listeners. The Sense of Wonder is Carson's intimate account of adventures with her young nephew, Roger, as they enjoy walks along the rocky coast of Maine and through dense forests and open fields, observing wildlife, strange plants, moonlight, and storm clouds, and listening to the "living music" of insects in the underbrush.

More than 12,000 years ago, in one of the greatest triumphs of prehistory, humans colonized North America, a continent that was then truly a new world. Just when and how they did so has been one of the most perplexing and controversial questions in archaeology.

All of us would like to live longer, or to slow the debilitating effects of age. In How We Age, Coleen Murphy shows how recent research on longevity and aging may be bringing us closer to this goal. Murphy, a leading scholar of aging, explains that the study of model systems, particularly simple invertebrate animals, combined with breakthroughs in genomic methods, have allowed scientists to probe the molecular mechanisms of longevity and aging.

The Age of Living Machines describes some of the most exciting new developments and the scientists and engineers who helped create them. Virus-built batteries. Protein-based water filters. Cancer-detecting nanoparticles. Mind-reading bionic limbs. Computer-engineered crops. Together they highlight the promise of the technology revolution of the 21st century to overcome some of the greatest humanitarian, medical, and environmental challenges of our time.

In The Synthetic Age, Christopher Preston argues that what is most startling about this coming epoch is not only how much impact humans have had but, more important, how much deliberate shaping they will start to do. Emerging technologies promise to give us the power to take over some of Nature's most basic operations. It is not just that we are exiting the Holocene and entering the Anthropocene; it is that we are leaving behind the time in which planetary change is just the unintended consequence of unbridled industrialism.

In the new essays collected here, an interdisciplinary group of scholars asks age-old questions about the nature and well-being of humans in the context of a revolutionary new biotechnology - one that has the potential to change the genetic make-up of both existing people and future generations. Welcoming listeners who study related issues and those not yet familiar with the formal study of bioethics, the authors of these essays open up a conversation about the ethics of gene editing.

The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures—including our own ancestors.

The emerging field of evolutionary psychology remains controversial, perhaps especially among Christians. Yet according to Justin Barrett and Pamela Ebstyne King, it can be a powerful tool for understanding human nature and our distinctively human purpose. Thriving with Stone Age Minds provides an introduction to evolutionary psychology, explaining key concepts like hyper-sociality, information gathering, and self-control.

Best-selling author Brian Fagan brings early humans out of the deep freeze with his trademark mix of erudition, cutting-edge science, and vivid storytelling. Cro-Magnon reveals human society in its infancy, facing enormous environmental challenges - including a rival species of humans, the Neanderthals. For ten millennia, Cro-Magnons lived side by side with Neanderthals, an encounter that Fagan fills with drama.

In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history - and our part in it - is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history.

As at home with Galileo and his daughter in Florence as he is with Diderot in Enlightenment France, William and Alice James in fin-de-siècle Boston, or the latest research on the genome, Gerald Weissmann distills the lessons of history to guide us through our troubled age. His message is clear: "Experimental science is our defense-perhaps our best defense-against humbug and the Endarkenment."

Through his documentary film series, The Human Longevity Project, Jason Prall traveled to select regions around the world known for their long-lived, healthy populations. He sought to understand not only the longevity secrets of these societies but also the scientific basis underpinning their...
