Of all the radioactive elements discovered at the end of the 19th century, it was radium that became the focus of both public fascination and entrepreneurial zeal. Half Lives tells the fascinating, curious, sometimes macabre story of the element through its ascendance as a desirable item - a present for a queen, a prize in a treasure hunt, a glow-in-the-dark dance costume - to its role as a supposed cure-all in everyday 20th-century life, when medical practitioners and business people (reputable and otherwise) devised ingenious ways of commodifying the new wonder element.

Author David Deamer addresses questions that are the cutting edge of research on the origin of life.

Carbon is the only element that animates the entirety of the living world. Though comprising a tiny fraction of Earth’s composition, our planet is lifeless without it. Yet it is maligned as the driver of climate change, scorned as an errant element blamed for the possible demise of civilization. Here, Paul Hawken looks at the flow of life through the lens of carbon. Embracing a panoramic view of carbon’s omnipresence, he explores how this ubiquitous and essential element extends into every aperture of existence and shapes the entire fabric of life.

Seventy years ago, Erwin Schrdinger posed a simple, yet profound, question: What is life?. How could the very existence of such extraordinary chemical systems be understood? This problem has puzzled biologists and physical scientists both before, and ever since. Living things are hugely complex and have unique properties, such as self-maintenance and apparently purposeful behaviour which we do not see in inert matter. So how does chemistry give rise to biology?
