Here are gripping accounts of unruly molecules and the diseases that form in their wake.A college student cannot remember if she has eaten breakfast. By dinner, she is strapped to a hospital bed, convinced she is battling zombies. A man planning to propose marriage instead becomes violently enraged, gripped by body spasms so severe that he nearly bites off his own tongue. One after another, poor farmers in South Carolina drop dead from a mysterious epidemic of dementia.With an intoxicating blend of history and intrigue, Sara Manning Peskin invites readers to play medical detective, tracing each diagnosis from the patient to an ailing nervous system. Along the way, Peskin entertains with tales of the sometimes outlandish, often criticized, and forever devoted scientists who discovered it all.Peskin never loses sight of the human impact of these conditions. Alzheimer’s Disease is more than the gradual loss of a loved one; it can be a family’s multigenerational curse. The proteins that abound in every cell of our bodies are not simply strings of oxygen, hydrogen, nitrogen, and carbon; they are the building blocks of our personalities and relationships. A Molecule Away from Madness is an unputdownable journey into the deepest mysteries of our brains.

    Origin provides an overview of these new histories throughout North and South America, and a glimpse into how the tools of genetics reveal details about human history and evolution.20,000 years ago, people crossed a great land bridge from Siberia into Western Alaska and then dispersed southward into what is now called the Americas. Until we venture out to other worlds, this remains the last time our species has populated an entirely new place, and this event has been a subject of deep fascination and controversy. No written records—and scant archaeological evidence—exist to tell us what happened or how it took place. Many different models have been proposed to explain how the Americas were peopled and what happened in the thousands of years that followed. A study of both past and present, Origin explores how genetics is currently being used to construct narratives that profoundly impact Indigenous peoples of the Americas. It serves as a primer for anyone interested in how genetics has become entangled with identity in the way that society addresses the question "Who is indigenous?"

    Along with this technological breakthrough there has emerged a movement to use this information to help prospective parents “eliminate preventable genetic disease.” As the prospect of systematically excluding the appearance of unwanted mutations in our children comes within reach, David B. Goldstein examines the possible consequences from these types of choices. Engaging and accessible, this clarion call for responsible and informed stewardship of the human genome provides an overview of what we do and do not know about human genetics and looks at some of the complex, yet largely unexplored, issues we must be most careful about as we move into an era of increasing numbers of parents exercising direct control over the genomes of their children.
