An "elegant", "engrossing" (Carol Tavris, Wall Street Journal) examination of what we think we know about the brain and why - despite technological advances - the workings of our most essential organ remain a mystery.

Everyone has heard the story of DNA as the story of Watson, Crick, and Rosalind Franklin, but knowing the structure of DNA was only part of a greater struggle to understand life's secrets. Life's Greatest Secret is the story of the discovery and cracking of the genetic code, the thing that ultimately enables a spiraling molecule to give rise to the life that exists all around us. This great scientific breakthrough has had far-reaching consequences for how we understand ourselves and our place in the natural world.

In 2018, scientists manipulated the DNA of human babies for the first time. As biologist and historian Matthew Cobb shows in As Gods, this achievement was one many scientists have feared from the start of the genetic age. Four times in the last fifty years, geneticists, frightened by their own technology, have called a temporary halt to their experiments. They ought to be frightened.

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.

What are the moments that make a life? In Francis Crick’s, the decisive moment came in 1951, when he first met James Watson. Their ensuing discovery of the structure of DNA made Crick world-famous. But neither that chance meeting nor that discovery made Crick who he was. As Matthew Cobb shows in Crick, it is another chance encounter, with a line from the writing of Beat poet Michael McClure, that reveals Crick’s character: “THIS IS THE POWERFUL KNOWLEDGE,” it shouted. Crick, having read it, would keep it with him for the rest of his life.

Recognizing that a historic study of American racism and police violence should become part of today's canon, Jelani Cobb contextualizes it for a new generation.
