For readers of Giulia Enders' Gut and Bill Bryson's The Body, a surprising, witty and sparkling exploration of the teeming microbiome of possibility in human feces from microbiologist and science journalist Bryn Nelson.

The future is sh*t: the literal kind. For most of human history we've been, well, disinclined to take a closer look at our body's natural product--the complex antihero of this story--save for gleaning some prophecy of our own health. But if we were to take more than a passing look at our poop, we would spy a veritable cornucopia of possibilities. We would see potent medicine, sustainable power, and natural fertilizer to restore the world's depleted lands. We would spy a time capsule of evidence for understanding past lives and murderous ends. We would glimpse effective ways of measuring and improving human health from the cradle to the grave, early warnings of community outbreaks like Covid-19, and new means of identifying environmental harm--and then reversing it.

Flush is both an urgent exploration of the world's single most squandered natural resource, and a cri de coeur (or cri de colon?) for the vast, hidden value in our "waste." Award-winning journalist and microbiologist Bryn Nelson, PhD, leads readers through the colon and beyond with infectious enthusiasm, helping to usher in a necessary mental shift that could restore our balance with the rest of the planet and save us from ourselves. Unlocking poop's enormous potential will require us to overcome our shame and disgust and embrace our role as the producers and architects of a more circular economy in which lowly byproducts become our species' salvation. Locked within you is a medicine cabinet, a biogas pipeline, a glass of drinking water, a mound of fuel briquettes; it's time to open the doors (carefully!). A dose of medicine, a glass of water, a gallon of rocket fuel, an acre of soil: sometimes hope arrives in surprising packages.
About the Author: Bryn Nelson, PhD, is an award-winning science writer and former microbiologist who decided he'd much rather write about microbes than experiment on them. After receiving his PhD from the University of Washington, he shifted course and completed a graduate program in science writing at the University of California at Santa Cruz. Since then, he has accumulated more than two decades of journalism experience, including seven years at the Newsday science desk where he covered genetics, stem cell research, evolution, ecology, and conservation. Nelson has written for dozens of other outlets, from The New York Times, NBCNews.com, and The Daily Beast to Nature, Mosaic, and Science News for Students.

Among his honors, Nelson has won an Association of Health Care Journalists award for larger newspapers and wire services, a New York Press Club award for best web-exclusive content, and two APEX Grand Awards for trade publication writing. In his spare time, he enjoys photography, singing, travel, and gardening in Seattle, where he lives with his husband, Geoff, and their energetic boxador, Piper.
