A new gene editing technology, invented just seven years ago, has turned humanity into gods. Enabling us to manipulate the genes in virtually any organism with exquisite precision, CRISPR has given scientists a degree of control that was undreamt of even in science fiction. But CRISPR is just the latest, giant leap in a long journey to master genetics. The Genetic Age shows the astonishing, world-changing potential of the new genetics and the possible threats it poses, sifting between fantasy and the reality when it comes to both benefits and dangers.

This is the story of our quest to understand the most mysterious object in the universe. Today we tend to picture the brain as a computer. Earlier scientists thought about it in their own technological terms: as a telephone switchboard, or a clock, or all manner of fantastic mechanical or hydraulic devices. Could the right metaphor unlock the brain's deepest secrets once and for all? Galloping through centuries of wild speculation and ingenious, sometimes macabre anatomical investigations, scientist and historian Matthew Cobb reveals how we came to our present state of knowledge.

Our sense of smell - or olfaction as it is technically known - is our most enigmatic sense. It can conjure up memories, taking us back to very specific places and emotions, whilst powerful smells can induce strong feelings of hunger or nausea. In the animal kingdom smell can be used to find food, a mate, or a home; to sense danger; and to send and receive complex messages with other members of a species. Yet despite its fundamental importance in our mental life and in the existence of all animals, our scientific understanding of how smell works is limited.

Francis Crick was a restless, relentless thinker, as fascinated by Beat poetry and psychedelics as the genetic meaning of life and the inner workings of the brain. Yet for all his drive, he was driven by collaboration: with Jim Watson on DNA, with artists in Cambridge and California, and with his wife Odile, who drew the figure of the double helix that illuminated his most famous discovery. It was his debates and conflicts with these collaborators that powered a mind in motion.
