Publisher's summary: 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.

Publisher's summary: For Laurah Norton, forensic science was always more of a passion than anything else. But after learning about a mishandled 1990s cold case involving missing twins, she was spurred to action, eventually creating a massively popular podcast and building a platform that helped bring widespread attention and resources to the case. LAY THEM TO REST builds on Laurah’s fascination with these investigations, introducing readers to the history and evolution of forensic science, from the death masks used in Ancient Rome to the 3-D facial reconstruction technology used today. Incorporating the stories of real-life John & Jane Does from around the world, Laurah also examines how changing identification methods have helped solve the most iconic cold cases. Along the way readers will also get to see Laurah solve a case in real time with forensic anthropologist Dr. Amy Michael, as they try to determine the identity of “Ina” Jane Doe, a woman whose head was found in a brush in an Illinois park in 1993.

More than just a chronicle of the history of forensics, LAY THEM TO REST is also a celebration of the growing field of experts, forensic artists, and anthropologists (many of whom Laurah talks to in the book), who work tirelessly to bring closure to these unsolved cases. And of course, this book asks why some cases go unsolved, highlighting the “missing missing,” the sex workers, undocumented, the cases that so desperately need our attention, but so rarely get it.
Engrossing, informative, heartbreaking, and hopeful, LAY THEM TO REST is a deep dive into the world of forensic science, showing readers how far we’ve come in cracking cases and catching killers, and illuminating just how far we have yet to go.

Publisher's summary: Earth has been reinventing itself for more than four billion years, keeping a record of its experiments in the form of rocks. Yet most of us live our lives on the planet with no idea of its extraordinary history, unable to interpret the language of the rocks that surround us. Geologist Marcia Bjornerud believes that our lives can be enriched by understanding our heritage on this old and creative planet.

Contrary to their reputation, rocks have eventful lives–and they intersect with our own in surprising ways. In Turning to Stone, Bjornerud reveals how rocks are the hidden infrastructure that keep the planet functioning, from sandstone aquifers purifying the water we drink to basalt formations slowly regulating global climate.

Bjornerud’s life as a geologist has coincided with an extraordinary period of discovery in the geosciences. From an insular girlhood in rural Wisconsin, she found her way to an unlikely career studying mountains in remote parts of the world and witnessed the emergence of a new understanding of the Earth as an animate system of rock, air, water and life. We are all, most fundamentally, Earthlings and we can find existential meaning and enduring wisdom in stone.
