Biological Age

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 2018, scientists manipulated the DNA of human babies for the first time. As biologist and historian Matthew Cobb shows in As Gods, this achievement was one many scientists have feared from the start of the genetic age. Four times in the last fifty years, geneticists, frightened by their own technology, have called a temporary halt to their experiments. They ought to be frightened.

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.

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.

Blending fiction with fact, 50 Dinosaur Tales imagines the way 50 newly described dinosaurs from the Triassic, Jurassic, and Cretaceous lived in their natural habitats. Also included is a list of fun facts for each dinosaur story and facts about 108 additional dinosaurs.

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.

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 Viral Storm, award-winning biologist Nathan Wolfe tells the story of how viruses and human beings have evolved side by side through history; how deadly viruses like HIV, swine flu, and bird flu almost wiped us out in the past; and why modern life has made our species vulnerable to the threat of a global pandemic. Wolfe's research missions to the jungles have earned him the nickname "the Indiana Jones of virus hunters," and here Wolfe takes listeners along on his groundbreaking and often dangerous research trips - to reveal the surprising origins of the most deadly diseases....

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.

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.

Natalie Armstrong has everything: She's smart and beautiful, has the perfect boyfriend, early acceptance to college, and a loving family. But the summer she turns 17, she finally decides to ask some unanswered questions: Who are her biological parents, and why did they give her up when she was born? These questions take her on a journey from the deep woods of Maine to the streets of New York City, from the pages of old phone books and a tattered yearbook photo to the realization that she might actually meet her biological mother face-to-face.

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.

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.

James T. Bradley introduces important biological principles and the basic procedures used in biotechnology. Various ethical issues - personhood, personal identity, privacy, ethnic discrimination, distributive justice, authenticity and human nature, and the significance of mortality in the human life cycle - are presented in a clear and unbiased manner.

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."

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.
