Today on Mushroom Hour we have the privilege of interviewing Phil Ross of MycoWorks. A pioneer in cultivating living materials for art and design, Phil began using mycelium in the 1990s as a medium for sculpture. Almost three decades on, Phil and his team of artists are now complemented by engineers, biologists, production specialists and material scientists in bringing the first Fine Mycelium™ material, Reishi™, to the world. Anyone who sees his work or hears him speak, can't help but have their mind set alight by a spark of inspiration. Phil is one of those unique individuals who can take something ancient, like fungi, and derive novel uses for it that not only shift how we see fungi, unlock new ideas and new fields of discovery, but really expand humanity's entire “realm of the possible”. His lifetime of work with mycelium hints at the vast ocean of infinite opportunities that await humanity as we explore kingdom fungi.    TOPICS COVERED:   Cooking as a Primer on the Practicum of Biotechnology  Push and Pull of Tropisms  Fungi as a Cypher to Understand Nature  From Forests to Graffiti - Learning to “Read” the Environment  Polypore Inspirations for Reishi™ Fine Mycelium Leather Products  Indigenous Use of Mycelium Leather  Medicinal Qualities of Reishi Mushrooms  Cultural Responses to the Gross and the Grotesque  Fashion as a Means of Communication  How MycoWorks Creates Reishi™ Fine Mycelium Leather  Mycelium Sheet Polymer & Leathercraft Learning Curves  Scaling Up to the Future of MycoWorks  The Transformation of Phil Ross  Future of Mycelium Materials   EPISODE RESOURCES:   Mycoworks website: https://www.mycoworks.com/  Mycoworks IG: https://www.instagram.com/mycoworks/  Louis Pasteur: https://en.wikipedia.org/wiki/Louis_Pasteur  Claude Levi-Strauss "The Raw and the Cooked": https://www.amazon.com/Raw-Cooked-Mythologiques-Claude-L%C3%A9vi-Strauss/dp/0226474879  Rudy Rucker "Ware Tetralogy": https://en.wikipedia.org/wiki/Ware_TetralogyCarl Woese: https://en.wikipedia.org/wiki/Carl_Woese  Susan Oyama "Evolution's Eye": https://www.amazon.com/Evolutions-Eye-Systems-Biology-Culture-Cultural/dp/0822324725  Ganoderma lucidum (fungus): https://en.wikipedia.org/wiki/Ganoderma_lucidum   Lenzites betulina (fungus): https://www.mushroomexpert.com/lenzites_betulina.html

This conversation is absolutely fascinating. In fact, it blew me away. My guest for this episode is science, nature, and travel writer David Quammen. David's books have included The Song of the Dodo, The Reluctant Mr. Darwin which chronicles' Charles Darwin's reluctance to publish his On the Origin of Species, Spillover which later informed shorter books Ebola and The Chimp and the River: How AIDS emerged from the African Forest. David has also written hundreds of articles for the likes of National Geographic, The New York Times, Rolling Stone, and The Atlantic, amongst others. The bulk of this episode however relates to David's latest book The Tangled Tree: A Radical New History of Life, which explores the dramatic revisions in our understanding of life's history on this planet caused by recent discoveries of genome sequencing and the story of a scientist called Carl Woese. You will also hear about the concept of ‘horizontal gene transfer' amongst others which revolutionises our understanding of the human genome, how we think about all species of life on earth and other profound and radical implications. David has a wonderful knack in his writing and speaking for making science understandable and pleasurable to absorb. We get into all of that and much more including: David's background in writing and how he got into writing about science and nature; Pandemics and what we know and don't know about them, drawing heavily on David's recent writing on the Ebola outbreak in West and Central Africa; The various themes of The Tangled Tree; The role of personalities in science – to quote David “science itself, however precise and objective is a human activity”; The risks and implications of some of the findings described in The Tangled Tree; Much, much more Show notes: David's website; David on Twitter; The Tangled Tree: A Radical History of Life on Earth; Review of the Tangled Tree in the New York Times Spillover; Ebola; The Chimp and the River: How AIDS Emerged From the African Forest; The Reluctant Mr. Darwin; Horizontal gene transfer; Carl Woese; Barbara McClintock; CRISPR  _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Get your free audio book and 30 day free trial at Audible: US listeners: get your free trial and audio book at Audible UK listeners: get your free trial and audio book at Audible _ _ _ _ _ _ _ _ __ _ _ _ _ _ _ Have you made a big decision lately?

My guest is David Quammen. In his new book The Tangled Tree: A Radical New History of Life (https://www.amazon.com/Tangled-Tree-Radical-History-Life/dp/1476776628), this nonpareil science writer explains how recent discoveries in molecular biology can change our understanding of evolution and life’s history, with powerful implications for human health and even our own human nature. In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field—the study of life’s diversity and relatedness at the molecular level—is horizontal gene transfer (HGT), or the movement of genes across species lines. It turns out that HGT has been widespread and important. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection—a type of HGT. In The Tangled Tree David Quammen, “one of that rare breed of science journalists who blends exploration with a talent for synthesis and storytelling” (Nature), chronicles these discoveries through the lives of the researchers who made them—such as Carl Woese, the most important little-known biologist of the twentieth century; Lynn Margulis, the notorious maverick whose wild ideas about “mosaic” creatures proved to be true; and Tsutomu Wantanabe, who discovered that the scourge of antibiotic-resistant bacteria is a direct result of horizontal gene transfer, bringing the deep study of genome histories to bear on a global crisis in public health. “Quammen is no ordinary writer. He is simply astonishing, one of that rare class of writer gifted with verve, ingenuity, humor, guts, and great heart” (Elle). Now, in The Tangled Tree, he explains how molecular studies of evolution have brought startling recognitions about the tangled tree of life—including where we humans fit upon it. Thanks to new technologies such as CRISPR, we now have the ability to alter even our genetic composition—through sideways insertions, as nature has long been doing. The Tangled Tree is a brilliant guide to our transformed understanding of evolution, of life’s history, and of our own human nature. David Quammen’s fifteen books include_ The Tangled Tree, The Song of the Dodo, The Reluctant Mr. Darwin, and _Spillover, a finalist for the National Book Critics Circle award. He has written for Harper’s, The Atlantic, Rolling Stone, The New York Times Book Review, Outside, and Powder, among other magazines, and is a contributing writer for National Geographic. He wrote the entire text of the May 2016 issue of National Geographic on the Greater Yellowstone ecosystem—the first time in the history of the magazine that an issue was single-authored. Quammen shares a home in Bozeman, Montana, with his wife, Betsy Gaines Quammen, an environmental historian, along with two Russian wolfhounds and a cross-eyed cat. Visit him at DavidQuammen.com.

David Quammen's book "The Tangled Tree: A New History of Life" tells the story of evolution through the eyes of Carl Woese, a not-terribly-famous but truly ingenious revolutionary who flipped evolution on its side, literally 90 degrees. He upended Darwin's famous tree of life, showing that genes can come from almost anywhere. Woese's contributions are believed by some to be as great as Darwin's. The view of evolution that Woese brought truly was a genuine revolution. Here, David Quammen engages with Perry Marshall in a wide ranging conversation about who the real heroes in evolutionary science actually are.

In this dialogue with one of the best nature and science writers of our generation, David Quammen and Michael Shermer discuss his new book on the history of one of the most exciting revolutions in evolution and genetics that is unfolding before our eyes. In the mid-1970s, scientists began using DNA sequences to reexamine the history of all life. Perhaps the most startling discovery to come out of this new field—the study of life’s diversity and relatedness at the molecular level—is horizontal gene transfer (HGT), or the movement of genes across species lines. It turns out that HGT has been widespread and important. For instance, we now know that roughly eight percent of the human genome arrived not through traditional inheritance from directly ancestral forms, but sideways by viral infection—a type of HGT.

As well, Quammen and Shermer discuss how molecular studies of evolution have brought startling recognitions about the tangled tree of life—including where we humans fit upon it. Thanks to new technologies such as CRISPR, we now have the ability to alter even our genetic composition—through sideways insertions, as nature has long been doing. They consider the ethical issues involved in bringing back extinct species, the meaning of the “self” if we are actually mosaics of different species, and the trans-humanist dream of re-engineering the human genome so our species can become post-human. David Quammen is the author of a dozen fiction and nonfiction books, including Blood Line and The Song of the Dodo. His book Spillover: Animal Infections and the Next Human Pandemic was a finalist for seven awards and received two of them: the Science and Society Book Award, given by the National Association of Science Writers, and the Society of Biology (UK) Book Award in General Biology. A three-time National Magazine Award winner, he is a contributing writer for National Geographic and has written also for Harper’s, Outside, Esquire, The Atlantic, Powder, and Rolling Stone. He received honorary doctorates from Montana State University and Colorado College. He travels widely on assignment, usually to jungles, mountains, remote islands, and swamps.

This is the first official podcast from thescientist, in the series; "Microbes, the little guys". In this episode we discuss the structure and information to expect from this podcast and also the taxonomic classification of life. The classification systems mentioned include the dichotomous Plant / Animal Linneas system, the 5 kingdom system by Whittaker and the widely adopted 3 Domain system by Carl Woese and George Fox. The three domain system proposed by Woese et al. had its basis in molecular biology rather than purely visual or structural characteristics and compares the sequence of the ribosome to create and identify evolutionary relationships as well as act as a bar code for the identification of organisms.
