Publisher Description
Life is the most extraordinary phenomenon in the known universe; but how does it work? Even in this age of cloning and synthetic biology, the remarkable truth remains: nobody has ever made anything living entirely out of dead material. Life remains the only way to make life. Are we missing a vital ingredient in its creation?
Like Richard Dawkins' The Selfish Gene, which provided a new perspective on evolution, Life on the Edge alters our understanding of life's dynamics as Jim Al-Khalili and Johnjoe Macfadden reveal the hitherto missing ingredient to be quantum mechanics. Drawing on recent ground-breaking experiments around the world, they show how photosynthesis relies on subatomic particles existing in many places at once, while inside enzymes, those workhorses of life that make every molecule within our cells, particles vanish from one point in space and instantly materialize in another.
Each chapter in Life on the Edge opens with an engaging example that illustrates one of life’s puzzles – How do migrating birds know where to go? How do we really smell the scent of a rose? How do our genes manage to copy themselves with such precision? – and then reveals how quantum mechanics delivers its answer. Guiding the reader through the maze of rapidly unfolding discovery, Al-Khalili and McFadden communicate vividly the excitement of this explosive new field of quantum biology, with its potentially revolutionary applications, and also offer insights into the biggest puzzle of all: what is life?
PUBLISHERS WEEKLY
It is a challenging task to find ways to bridge two highly technical disciplines for the general reader, but McFadden, a molecular geneticist, and Al-Khalili, a theoretical physicist, attempt it with some success, using the principles of quantum mechanics to explain the intricacies of molecular biology. As the authors note, "quantum mechanics is utterly counterintuitive," so bringing readers to the point where they can understand the topic well enough to appreciate how it might be applied to biological problems is nearly impossible. Nevertheless, McFadden and Al-Khalili find ways to present the results of some recent scientific studies so as to make the case that quantum mechanics likely plays a role in biological topics as diverse as enzymatic reactions, olfaction, and animal migration. They get a bit more speculative when they posit that such interactions may be responsible for many genetic mutations, consciousness, and the origin of life. They pay particular attention to Erwin Schr dinger's 1944 book, What Is Life, claiming that many of the ideas set forth in that slim volume were both correct and essential for our current understanding of biology. However, most biologists and historians of biology disagree with the latter assertion. Until more experimentation catches up with the speculation offered, McFadden and Khalili's interesting ideas are unlikely to be persuasive.
