Soft cover. Condizione: Good. 12pp extract, salvaged from a damaged issue of the North American Review, Volume 149, No. 4, October, 1889. The author, a professor of mechanical drawing at the Stevens Institute of Technology, was formerly the chief draughtsman for Captain John Ericsson. From the text, "The story of the Monitor's building has been often told: the fertility of invention, facility in designing, speed and accuracy in drawing, promptness in execution, and unwearied industry which made the construction possible in so short a time -- all these are familiar. But the minor mishaps, the special incidents which, apparently adverse, yet proved providential as contributing to that exact coincidence of time, place, and circumstance upon which so much depended -- these have as yet been omitted in the telling, and without them the story is incomplete." Housed in mylar report cover. …

Paperback. Condizione: new. Paperback. 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?

Paperback. Condizione: new. Paperback. A concise primer that complicates a convenient truth in biologythe divide between germ and somatic cellswith far-reaching ethical and public policy ramifications. Scientists have long held that we two have kinds of cellsgerm and soma. Make a change to germ cellssay using genome editingand that change will appear in the cells of future generations. Somatic cells are safe after such tampering; modify your skin cells, and your future childrens 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 cellsthe so-called Weismann Barrierand 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.
