Biological Age

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.

Oxygen takes the listener on an enthralling journey, as gripping as a thriller, as it unravels the unexpected ways in which oxygen spurred the evolution of life and death.

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.

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.

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.

Synthetic biology promises to reveal how life is created and how it can be re-created, enabling scientists to rewrite the rules of our reality. It could help us, for example, heal without prescription medications, grow meat without harvesting animals, or confront our looming climate catastrophe. Synthetic biology will determine the ways in which we conceive future generations and how we define family, how we identify disease and treat aging, where we make our homes, and how we nourish ourselves.

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 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.

Professor Rose Anne Kenny has 35 years of experience at the forefront of ageing medicine. In Age Proof, she draws on her own pioneering research and the latest evidence to demystify why we age and shows us that 80% of our ageing biology is within our control: we can not only live longer lives but become happier and healthier deep into our later years.

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.

Over more than 25 years of teaching and research, Christine Desdemaines-Hugon has become an unrivaled expert in the cave art and artists of the Dordogne region. In Stepping-Stones she combines her expertise in both art and archaeology to convey an intimate understanding of the "cave experience." Her keen insights communicate not only the incomparable artistic value of these works but also the near-spiritual impact of viewing them for oneself.

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 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.

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.

Lee Hood did that rarest of things. He enabled scientists to see things they couldn't see before and do things they hadn't dreamed of doing. Scientists can now sequence complete human genomes in a day, setting in motion a revolution that is personalizing medicine. Hood, a son of the American West, was an unlikely candidate to transform biology. But with ferocious drive, he led a team at Caltech that developed the automated DNA sequencer, the tool that paved the way for the Human Genome Project.

By being able to receive downloaded messages from wild and domestic animals, Shawndra translates their messages for us. These animals have shared powerful messages of unity, connection and purpose, and steps that each of us are able to take to deepen the connection, find more meaning in our lives, and become the humans that the animals know we can be. You'll hear messages from 12 different animals on what they want us to know in order to live a more profoundly amazing life.

As recently as 11,000 years ago - "near time" to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age.

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.

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.
