A fresh look at electricity and its powerful role in life on Earth When we think of electricity, we likely imagine the energy humming inside our home appliances or lighting up our electronic devices—or perhaps we envision the lightning-streaked clouds of a stormy sky. But electricity is more than an external source of power, heat, or illumination. Life at its essence is nothing if not electrical. The story of how we came to understand electricity’s essential role in all life is rooted in our observations of its influences on the body—influences governed by the body’s central nervous system. Spark explains the science of electricity from this fresh, biological perspective. Through vivid tales of scientists and individuals—from Benjamin Franklin to Elon Musk—Timothy Jorgensen shows how our views of electricity and the nervous system evolved in tandem, and how progress in one area enabled advancements in the other. He explains how these developments have allowed us to understand—and replicate—the ways electricity enables the body’s essential functions of sight, hearing, touch, and movement itself. Throughout, Jorgensen examines our fascination with electricity and how it can help or harm us. He explores a broad range of topics and events, including the Nobel Prize–winning discoveries of the electron and neuron, the history of experimentation involving electricity’s effects on the body, and recent breakthroughs in the use of electricity to treat disease. Filled with gripping adventures in scientific exploration, Spark offers an indispensable look at electricity, how it works, and how it animates our lives from within and without.

Demonstrates the importance of electricity and electrical devices in everyday life and explains where electricty comes from and how it gets from the power plant to the socket.

"This is a wonderful book. Frances Ashcroft has a rare gift for making difficult subjects accessible and fascinating." —Bill Bryson, author of The Body: A Guide for Occupants What happens during a heart attack? Can someone really die of fright? What is death, anyway? How does electroshock treatment affect the brain? What is consciousness? The answers to these questions lie in the electrical signals constantly traveling through our bodies, driving our thoughts, our movements, and even the beating of our hearts. The history of how scientists discovered the role of electricity in the human body is a colorful one, filled with extraordinary personalities, fierce debates, and brilliant experiments. Moreover, present-day research on electricity and ion channels has created one of the most exciting fields in science, shedding light on conditions ranging from diabetes and allergies to cystic fibrosis, migraines, and male infertility. With inimitable wit and a clear, fresh voice, award-winning researcher Frances Ashcroft weaves together compelling real-life stories with the latest scientific findings, giving us a spectacular account of the body electric.

The most misunderstood force driving health and disease The story of the invention and use of electricity has often been told before, but never from an environmental point of view. The assumption of safety, and the conviction that electricity has nothing to do with life, are by now so entrenched in the human psyche that new research, and testimony by those who are being injured, are not enough to change the course that society has set. Two increasingly isolated worlds--that inhabited by the majority, who embrace new electrical technology without question, and that inhabited by a growing minority, who are fighting for survival in an electrically polluted environment--no longer even speak the same language. In The Invisible Rainbow, Arthur Firstenberg bridges the two worlds. In a story that is rigorously scientific yet easy to read, he provides a surprising answer to the question, "How can electricity be suddenly harmful today when it was safe for centuries?"

Mitochondria are tiny structures located inside our cells that carry out the essential task of producing energy for the cell. They are found in all complex living things, and in that sense, they are fundamental for driving complex life on the planet. But there is much more to them than that. Mitochondria have their own DNA, with their own small collection of genes, separate from those in the cell nucleus. It is thought that they were once bacteria living independent lives. Their enslavement within the larger cell was a turning point in the evolution of life, enabling the development of complex organisms and, closely related, the origin of two sexes. Unlike the DNA in the nucleus, mitochondrial DNA is passed down exclusively (or almost exclusively) via the female line. That's why it has been used by some researchers to trace human ancestry daughter-to-mother, to 'Mitochondrial Eve'. Mitochondria give us important information about our evolutionary history. And that's not all. Mitochondrial genes mutate much faster than those in the nucleus because of the free radicals produced in their energy-generating role. This high mutation rate lies behind our ageing and certain congenital diseases. The latest research suggests that mitochondria play a key role in degenerative diseases such as cancer, through their involvement in precipitating cell suicide. Mitochondria, then, are pivotal in power, sex, and suicide. In this fascinating and thought-provoking book, Nick Lane brings together the latest research findings in this exciting field to show how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death. 'An extraordinary account of groundbreaking modern science... The book abounds with interesting and important ideas.' Mark Ridley, Department of Zoology, University of Oxford

In a culture obsessed with happiness, this wise, stirring book points the way toward a richer, more satisfying life. Too many of us believe that the search for meaning is an esoteric pursuit—that you have to travel to a distant monastery or page through dusty volumes to discover life’s secrets. The truth is, there are untapped sources of meaning all around us—right here, right now. To explore how we can craft lives of meaning, Emily Esfahani Smith synthesizes a kaleidoscopic array of sources—from psychologists, sociologists, philosophers, and neuroscientists to figures in literature and history such as George Eliot, Viktor Frankl, Aristotle, and the Buddha. Drawing on this research, Smith shows us how cultivating connections to others, identifying and working toward a purpose, telling stories about our place in the world, and seeking out mystery can immeasurably deepen our lives. To bring what she calls the four pillars of meaning to life, Smith visits a tight-knit fishing village in the Chesapeake Bay, stargazes in West Texas, attends a dinner where young people gather to share their experiences of profound loss, and more. She also introduces us to compelling seekers of meaning—from the drug kingpin who finds his purpose in helping people get fit to the artist who draws on her Hindu upbringing to create arresting photographs. And she explores how we might begin to build a culture that leaves space for introspection and awe, cultivates a sense of community, and imbues our lives with meaning. Inspiring and story-driven, The Power of Meaning will strike a profound chord in anyone seeking a life that matters.
