A concise primer that complicates a convenient truth in biology—the divide between germ and somatic cells—with far-reaching ethical and public policy ramifications.   Scientists have long held that we two have kinds of cells—germ and soma. Make a change to germ cells—say using genome editing—and that change will appear in the cells of future generations. Somatic cells are “safe� after such tampering; modify your skin cells, and your future children’s skin cells will never know. And, while germ cells can give rise to new generations (including all of the somatic cells in a body), somatic cells can never become germ cells. How did scientists discover this relationship and distinction between somatic and germ cells—the so-called Weismann Barrier—and does it actually exist? Can somatic cells become germ cells in the way germ cells become somatic cells? That is, can germ cells regenerate from somatic cells even though conventional wisdom denies this possibility? Covering research from the late nineteenth century to the 2020s, historian and philosopher of science Kate MacCord explores how scientists came to understand and accept the dubious concept of the Weismann Barrier and what profound implications this convenient assumption has for research and policy, from genome editing to stem cell research, and much more.

The original 1818 text of Mary Shelley's classic novel, with annotations and essays highlighting its scientific, ethical, and cautionary aspects. Mary Shelley's Frankenstein has endured in the popular imagination for two hundred years. Begun as a ghost story by an intellectually and socially precocious eighteen-year-old author during a cold and rainy summer on the shores of Lake Geneva, the dramatic tale of Victor Frankenstein and his stitched-together creature can be read as the ultimate parable of scientific hubris. Victor, "the modern Prometheus," tried to do what he perhaps should have left to Nature: create life. Although the novel is most often discussed in literary-historical terms-as a seminal example of romanticism or as a groundbreaking early work of science fiction-Mary Shelley was keenly aware of contemporary scientific developments and incorporated them into her story. In our era of synthetic biology, artificial intelligence, robotics, and climate engineering, this edition of Frankenstein will resonate forcefully for readers with a background or interest in science and engineering, and anyone intrigued by the fundamental questions of creativity and responsibility. This edition of Frankenstein pairs the original 1818 version of the manuscript-meticulously line-edited and amended by Charles E. Robinson, one of the world's preeminent authorities on the text-with annotations and essays by leading scholars exploring the social and ethical aspects of scientific creativity raised by this remarkable story. The result is a unique and accessible edition of one of the most thought-provoking and influential novels ever written. Essays by Elizabeth Bear, Cory Doctorow, Heather E. Douglas, Josephine Johnston, Kate MacCord, Jane Maienschein, Anne K. Mellor, Alfred Nordmann

Two historians and philosophers of science offer an essential primer on the meaning and limits of regeneration. In punishment for his stealing fire, the Greek gods chained Prometheus to a rock, where every day an eagle plucked out his liver, and every night the liver regenerated. While Prometheus may be a figure of myth, scholars today ask whether ancient Greeks knew that the human liver does, in fact, have a special capacity to regenerate. Some organs and tissues can regenerate, while others cannot, and some organisms can regenerate more fully and more easily than others. Cut an earthworm in half, and two wiggly worms may confront you. Cut off the head of a hydra, and it may grow a new head. Cut off a human arm, and the human will be missing an arm. Why the differences? What are the limits of regeneration, and how, when, and why does it occur? In this book, historians and philosophers of science Jane Maienschein and Kate MacCord explore biological regeneration, delving into a topic of increasing interest in light of regenerative medicine, new tools in developmental and neurobiology, and the urgent need to understand and repair damage to ecosystems brought on by climate change. Looking across scales, from germ, nerve, and stem cells to individual organisms and complex systems, this short and accessible introduction poses a range of deep and provocative questions: What conditions allow some damaged microbiomes to regenerate where others do not? Why are forests following a fire said to regenerate sometimes but not always? And in the face of climate change in the era called the Anthropocene, can the planet regenerate to become healthy again, or will the global ecosystem collapse?

The author speaks the local language and has interviewed and conversed with hundreds of Afghans, both men and women. She listened to their stories and lived among them. And in the midst of all of that, she found Kingdom responses to the beliefs Afghani Muslims hold to be true.Riveting and fast paced, " In the Land of Blue Burqas" depicts sharing the love and truth of Christ with women living in Afghanistan which has been called "the world's most dangerous country in which to be born a woman." These stories are honest and true. The harsh reality of their lives is not sugar-coated and that adds to the impact of the book. Through storytelling the author shows how people who don't know Christ come to see Him, His truth and His beauty. The stories provide insight into how a Jesus-follower brought Jesus' teachings of the Kingdom of God to Afghanistan. They reveal the splendor of Christ, the desire of human hearts, and that precious instance where the two meet.
This is a collection of vignettes tethered together by the real danger that muslim women face in Afghanistan. These are firsthand accounts from the authors experience drawn from living among these women. The reader will see just how revolutionary Christ's message is today, and how radical it was during Christ's lifetime - the present day Afghan cultural attitudes are not unlike they were 2000 years ago. All of the names of those involved - including Kate's - plus the locations have been changed to protect the participants. Just take a few minutes and read the opening pages. You'll be hooked.
