Exploring the most transformative breakthroughs in biology since the discovery of the double helix, a Nobel Prize–winning scientist unveils the RNA age.

For over half a century, DNA has dominated science and the popular imagination as the “secret of life.” But over the last several decades, a quiet revolution has taken place. In a series of breathtaking discoveries, the biochemist Thomas R. Cech and a diverse cast of brilliant scientists have revealed that RNA―long overlooked as the passive servant of DNA―sits at the center of biology’s greatest mysteries: How did life begin? What makes us human? Why do we get sick and grow old? In The Catalyst, Cech finally brings together years of research to demonstrate that RNA is the true key to understanding life on Earth, from its very origins to our future in the twenty-first century.

A gripping journey of discovery, The Catalyst moves from the early experiments that first hinted at RNA’s spectacular powers, to Cech’s own paradigm-shifting finding that it can catalyze cellular reactions, to the cutting-edge biotechnologies poised to reshape our health. We learn how RNA―once thought merely to transmit DNA’s genetic instructions to the cell’s protein-making machinery―may have jump-started life itself, and how, at the same time, it can cut our individual lives short through viral diseases and cancer. We see how RNA is implicated in the aging process and explore the darker depths of the supposed fountain of youth, telomerase. And we catch a thrilling glimpse into how RNA-powered therapies―from CRISPR, the revolutionary tool that uses RNA to rewrite the code of life, to the groundbreaking mRNA vaccines that have saved millions during the pandemic, and more―may enable us to improve and even extend life beyond nature’s current limits.

Written by one of our foremost scientists, The Catalyst is a must-read guide to the present and future of biology and medicine.

The idea that changes in biodiversity can impact how ecosystems function has, over the last quarter century, gone from being a controversial notion to an accepted part of science and policy. As the field matures, it is high time to review progress, explore the links between this new research area and fundamental ecological concepts, and look ahead to the implementation of this knowledge. This book is designed to both provide an up-to-date overview of research in the area and to serve as a useful textbook for those studying the relationship between biodiversity and the functioning, stability and services of ecosystems. The Ecological and Societal Consequences of Biodiversity Loss is aimed at a wide audience of upper undergraduate students, postgraduate students, and academic and research staff.
