Book Description
In science, sometimes it is best to keep things simple. Initially discrediting the discovery of neurons in jellyfish, mid-nineteenth-century scientists grouped jellyfish, comb-jellies, hydra, and sea anemones together under one term - "coelenterates" - and deemed these animals too similar to plants to warrant a nervous system. In Dawn of the Neuron, Michel Anctil shows how Darwin's theory of evolution completely eradicated this idea and cleared the way for the modern study of the neuron. Once zoologists accepted the notion that varying levels of animal complexity could evolve, they began to use simple-structured creatures such as coelenterates and sponges to understand the building blocks of more complicated nervous systems. Dawn of the Neuron provides fascinating insights into the labours and lives of scientists who studied coelenterate nervous systems over several generations, and who approached the puzzling origin of the first nerve cells through the process outlined in evolutionary theory. Anctil also reveals how these scientists, who were willing to embrace improved and paradigm-changing scientific methods, still revealed their cultural backgrounds, their societal biases, and their attachments to schools of thought and academic traditions while presenting their ground-breaking work. Their attitudes toward the neuron doctrine - where neurons are individual, self-contained cells - proved decisive in the exploration of how neurons first emerged. Featuring photographs and historical sketches to illustrate this quest for knowledge, Dawn of the Neuron is a remarkably in-depth exploration of the link between Darwin's theory of evolution and pioneering studies and understandings of the first evolved nervous systems

Book Description
In the depths of the big, wide sea, the little jellyfish hears a thoomp. What is this mysterious sound? With magical collage illustrations, this is a joyous, read-aloud picture book about the uniqueness of every creature's heart. A wise fish explains to the jellyfish that the loud thoomp is a heartbeat. The jellyfish listens to the soft heartbeat of the wise fish. Sadly, she realises she has no heartbeat herself though, and she still needs to find the very loud thoomp. So off she swims to search for it. Along the way, she meets all kinds of creatures and learns about their heartbeats, from the seal to the whale to the octopus that has three hearts! But why can't she hear her own? Packed with fascinating scientific knowledge, including extra pages about the unique hearts of more amazing creatures, this engaging book conveys the incredible diversity of life on Earth, and encourages everyone to love how they are different and to celebrate being themselves.

Book Description
“Henderson teaches us how to wonder anew with a new vision of science illuminated by a rich range of literature, philosophy, art, and music.” —Hugh Aldersey-Williams, author of Dutch Light We live in a world that is known, every corner thoroughly explored. But has this knowledge cost us the ability to wonder? Wonder, Caspar Henderson argues, is at its most supremely valuable in just such a world because it reaffirms our humanity and gives us hope for the future. That’s the power of wonder, and that’s what we should aim to cultivate in our lives. But what are the wonders of the modern world? Henderson’s brilliant exploration borrows from the form of one of the oldest and most widely known sources of wonder: maps. Large, detailed mappae mundi invited people in medieval Europe to vividly imagine places and possibilities they had never seen before: manticores with the head of a man, the body of a lion, and the stinging tail of a scorpion; tribes of one-eyed men who fought griffins for diamonds; and fearsome Scythian warriors who drank the blood of their enemies from their skulls. A New Map of Wonders explores these and other realms of the wonderful, in different times and cultures and in the present day, taking readers from Aboriginal Australian landscapes to sacred sites in Great Britain, all the while keeping sight questions such as the cognitive basis of wonder and the relationship between wonder and science. Beautifully illustrated and written with wit and moral complexity, this sequel to The Book of Barely Imagined Beings is a fascinating account of the power of wonder and an unforgettable meditation on its importance to our future.

Book Description
"A book full of wonders" —Helen Macdonald, author of H Is for Hawk "Witty, insightful. . . .The story of jellyfish. . . is a significant part of the environmental story. Berwald's engaging account of these delicate, often ignored creatures shows how much they matter to our oceans' future." —New York Times Book Review Jellyfish have been swimming in our oceans for well over half a billion years, longer than any other animal that lives on the planet. They make a venom so toxic it can kill a human in three minutes. Their sting—microscopic spears that pierce with five million times the acceleration of gravity—is the fastest known motion in the animal kingdom. Made of roughly 95 percent water, some jellies are barely perceptible virtuosos of disguise, while others glow with a luminescence that has revolutionized biotechnology. Yet until recently, jellyfish were largely ignored by science, and they remain among the most poorly understood of ocean dwellers. More than a decade ago, Juli Berwald left a career in ocean science to raise a family in landlocked Austin, Texas, but jellyfish drew her back to the sea. Recent, massive blooms of billions of jellyfish have clogged power plants, decimated fisheries, and caused millions of dollars of damage. Driven by questions about how overfishing, coastal development, and climate change were contributing to a jellyfish population explosion, Juli embarked on a scientific odyssey. She traveled the globe to meet the biologists who devote their careers to jellies, hitched rides on Japanese fishing boats to see giant jellyfish in the wild, raised jellyfish in her dining room, and throughout it all marveled at the complexity of these alluring and ominous biological wonders. Gracefully blending personal memoir with crystal-clear distillations of science, Spineless is the story of how Juli learned to navigate and ultimately embrace her ambition, her curiosity, and her passion for the natural world. She discovers that jellyfish science is more than just a quest for answers. It’s a call to realize our collective responsibility for the planet we share.

Book Description
Silicon Valley in the 2030s is not so different from today, filled with vaguely sexist CEOs, contested inequality politics, and startups that are almost a joke. After she loses her job when her startup folds and loses her home to California's annual wildfires, Sara joins the latest thing: an unnamed tech giant's quasi-utopian community, floating above the drowned land that was once Monterey. Alone on the inside with a thousand mysteriously chosen strangers, Sara is insulated by an all-powerful corporation from the turmoil of crumbling governments and a changing climate. Everyone around her seems incredibly thankful, rescued from gig work and student loans and bad news, but she can't find her own gratitude. As she learns more about her new home, she begins to see the cracks in its perfect facade. She must choose between surveillance and lies from the anonymous algorithms that protect her or face a vulnerable life outside the system to which she has signed away her next five years. Leaving, she learns, may not even be an option.
