Biological Age

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.

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.

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 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."

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.
