Entangled Life: How Fungi Make Our Worlds, Change Our Minds & Shape Our Futures


Merlin Sheldrake - 2020
    It can be microscopic, yet also accounts for the largest organisms ever recorded, living for millennia and weighing tens of thousands of tonnes. Its ability to digest rock enabled the first life on land, it can survive unprotected in space, and thrives amidst nuclear radiation.In this captivating adventure, Merlin Sheldrake explores the spectacular and neglected world of fungi: endlessly surprising organisms that sustain nearly all living systems. They can solve problems without a brain, stretching traditional definitions of ‘intelligence’, and can manipulate animal behaviour with devastating precision. In giving us bread, alcohol and life-saving medicines, fungi have shaped human history, and their psychedelic properties, which have influenced societies since antiquity, have recently been shown to alleviate a number of mental illnesses. The ability of fungi to digest plastic, explosives, pesticides and crude oil is being harnessed in break-through technologies, and the discovery that they connect plants in underground networks, the ‘Wood Wide Web’, is transforming the way we understand ecosystems. Yet they live their lives largely out of sight, and over ninety percent of their species remain undocumented.Entangled Life is a mind-altering journey into this hidden kingdom of life, and shows that fungi are key to understanding the planet on which we live, and the ways we think, feel and behave. The more we learn about fungi, the less makes sense without them.

Inside Animal Minds: The New Science of Animal Intelligence


Virginia Morell - 2012
    She introduces you to an African gray parrot named Alex, a bonobo named Kanzi, and a border collie named Betsy. Each of these animals tells us something interesting about the way they perceive and manipulate their world. The article also looks at what scientists are learning about the intelligence of dolphins and crows, beyond mere communication.   In “Almost Human,” Mary Roach takes us to the savannahs of Senegal to meet a group of 34 chimpanzees, whose behavior and social structures have given scientists some important clues about the nature of their communication and intelligence.   In “The Genius of Swarms,” Peter Miller looks at the collective behavior of ants, bees, and other insects for what they can tell us about social organization and how sometimes intelligence lies outside of the individual brain. This article served as the basis for his book, The Smart Swarm: How Understanding Flocks, Schools, and Colonies Can Make Us Better at Communicating, Decision Making, and Getting Things Done.

Out of Thin Air: Dinosaurs, Birds, and Earth's Ancient Atmosphere


Peter D. Ward - 2006
    But what accounts for the incredible longevity of dinosaurs? A renowned scientist now provides a startling explanation that is rewriting the history of the Age of Dinosaurs. Dinosaurs were pretty amazing creatures--real-life monsters that have the power to fascinate us. And their fiery Hollywood ending only serves to make the story that much more dramatic. But fossil evidence demonstrates that dinosaurs survived several mass extinctions, and were seemingly unaffected by catastrophes that decimated most other life on Earth. What could explain their uncanny ability to endure through the ages? Biologist and earth scientist Peter Ward now accounts for the remarkable indestructibility of dinosaurs by connecting their unusual respiration system with their ability to adapt to Earth's changing environment--a system that was ultimately bequeathed to their descendants, birds. By tracing the evolutionary path back through time and carefully connecting the dots from birds to dinosaurs, Ward describes the unique form of breathing shared by these two distant relatives and demonstrates how this simple but remarkable characteristic provides the elusive explanation to a question that has thus far stumped scientists. Nothing short of revolutionary in its bold presentation of an astonishing theory, Out of Thin Air is a story of science at the edge of discovery. Ward is an outstanding guide to the process of scientific detection. Audacious and innovative in his thinking, meticulous and thoroughly detailed in his research, only a scientist of his caliber is capable of telling this surprising story.

The Ends of the World: Supervolcanoes, Lethal Oceans, and the Search for Past Apocalypses


Peter Brannen - 2017
    In The Ends of the World, Peter Brannen dives into deep time, exploring Earth’s past dead ends, and in the process, offers us a glimpse of our possible future.Many scientists now believe that the climate shifts of the twenty-first century have analogs in these five extinctions. Using the visible clues these devastations have left behind in the fossil record, The Ends of the World takes us inside “scenes of the crime,” from South Africa to the New York Palisades, to tell the story of each extinction. Brannen examines the fossil record—which is rife with creatures like dragonflies the size of sea gulls and guillotine-mouthed fish—and introduces us to the researchers on the front lines who, using the forensic tools of modern science, are piecing together what really happened at the crime scenes of the Earth’s biggest whodunits.Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave, and casts our future in a completely new light.

Pandemics: Our Fears and the Facts (Kindle Single)


Sunetra Gupta - 2013
    As recently as 1918, a pandemic of influenza claimed over 50 million lives worldwide. The advent of drugs and vaccines led to an era of hope when we thought our battles with infectious disease were won, but our optimism has been eroded by the recognition that many pathogens have the capacity to transform themselves and escape our efforts to eradicate them. Are we now facing an inevitable repeat of a calamity such as the 1918 influenza pandemic or the Black Death? Can we anticipate and thwart such an event, or are we wilfully creating the conditions that would promote the emergence of new and highly virulent human infectious disease?Sunetra Gupta is Professor of Theoretical Epidemiology at the University of Oxford specialising in infectious diseases. She holds a bachelor's degree from Princeton University and a Ph.D. from the University of London. She has been awarded the Scientific Medal by the Zoological Society of London and the Royal Society Rosalind Franklin Award for her scientific research. She is also a novelist whose books have been awarded the Sahitya Akademi Award, the Southern Arts Literature Prize, shortlisted for the Crossword Award, and longlisted for the DSC and Orange Prizes.

The Big Ones: How Natural Disasters Have Shaped Us and What We Can Do about Them


Lucy Jones - 2018
    Geological Survey, a lively and revealing history of the world's most disruptive natural disasters, their impact on our culture, and new ways of thinking about the ones to comeNatural disasters emerge from the same forces that give our planet life. Earthquakes have provided us with natural springs. Volcanoes have given us fertile soil. A world without floods would be a world without rain. It is only when these forces exceed our ability to withstand them that they become disasters. Together, these colossal events have shaped our cities and their architecture; elevated leaders and toppled governments; influenced the way we reason, feel, fight, unite, and pray. The history of natural disasters is a history of ourselves.The Big Ones is a look at some of the most devastating disasters in human history, whose reverberations we continue to feel today. It considers Pompeii, and how a volcanic eruption in the first century AD challenged and reinforced prevailing views of religion for centuries to come. It explores the California floods of 1862, examining the failures of our collective memory. And it transports us to today, showing what Hurricane Katrina and the 2004 Indian Ocean tsunami can tell us about governance and globalization. With global temperatures rising, natural disasters are striking with greater frequency. More than just history, The Big Ones is a call to action. Natural disasters are inevitable; human catastrophes are not. With this energizing and richly researched book, Jones offers a look at our past, readying us to face down the Big Ones in our future.

The World Without Us


Alan Weisman - 2007
    In this far-reaching narrative, Weisman explains how our massive infrastructure would collapse and finally vanish without human presence; which everyday items may become immortalized as fossils; how copper pipes and wiring would be crushed into mere seams of reddish rock; why some of our earliest buildings might be the last architecture left; and how plastic, bronze sculpture, radio waves, and some man-made molecules may be our most lasting gifts to the universe.The World Without Us reveals how, just days after humans disappear, floods in New York's subways would start eroding the city's foundations, and how, as the world's cities crumble, asphalt jungles would give way to real ones. It describes the distinct ways that organic and chemically treated farms would revert to wild, how billions more birds would flourish, and how cockroaches in unheated cities would perish without us. Drawing on the expertise of engineers, atmospheric scientists, art conservators, zoologists, oil refiners, marine biologists, astrophysicists, religious leaders from rabbis to the Dalai Lama, and paleontologists—who describe a prehuman world inhabited by megafauna like giant sloths that stood taller than mammoths—Weisman illustrates what the planet might be like today, if not for us.From places already devoid of humans (a last fragment of primeval European forest; the Korean DMZ; Chernobyl), Weisman reveals Earth's tremendous capacity for self-healing. As he shows which human devastations are indelible, and which examples of our highest art and culture would endure longest, Weisman's narrative ultimately drives toward a radical but persuasive solution that needn't depend on our demise. It is narrative nonfiction at its finest, and in posing an irresistible concept with both gravity and a highly readable touch, it looks deeply at our effects on the planet in a way that no other book has.
