Seashells are the sculpted homes of a remarkable group of animals: the molluscs. These are some of the most ancient and successful animals on the planet. But watch out. Some molluscs can kill you if you eat them. Some will kill you if you stand too close. That hasn't stopped people using shells in many ways over thousands of years. They became the first jewelry and oldest currencies; they've been used as potent symbols of sex and death, prestige and war, not to mention a nutritious (and tasty) source of food. Spirals in Time is an exuberant aquatic romp, revealing amazing tales of these undersea marvels. Helen Scales leads us on a journey into their realm, as she goes in search of everything from snails that 'fly' underwater on tiny wings to octopuses accused of stealing shells and giant mussels with golden beards that were supposedly the source of Jason's golden fleece, and learns how shells have been exchanged for human lives, tapped for mind-bending drugs and inspired advances in medical technology. Weaving through these stories are the remarkable animals that build them, creatures with fascinating tales to tell, a myriad of spiralling shells following just a few simple rules of mathematics and evolution. Shells are also bellwethers of our impact on the natural world. Some species have been overfished, others poisoned by polluted seas; perhaps most worryingly of all, molluscs are expected to fall victim to ocean acidification, a side-effect of climate change that may soon cause shells to simply melt away. But rather than dwelling on what we risk losing, Spirals in Time urges you to ponder how seashells can reconnect us with nature, and heal the rift between ourselves and the living world.

'Scales's genuine appreciation and awe for fish are contagious.'- Science 'Delightful' - New Scientist Seventy per cent of the earth's surface is covered by water. This vast aquatic realm is inhabited by a multitude of strange creatures and reigning supreme among them are the fish. There are giants that live for centuries and thumb-sized tiddlers that survive only weeks; they can be pancake-flat or inflatable balloons; they can shout with colours or hide in plain sight, cheat and dance, remember and say sorry; some rarely budge while others travel the globe restlessly. And yet the mesmerising and complex lives of fish remain largely underrated and unseen, living hidden beneath the waterline, out of sight and out of mind. Helen Scales is our guide on an underwater journey, as we fathom the depths and watch these animals going about the glorious business of being fish. As well as the fish, we meet devoted fishwatchers past and present, from voodoo zombie potion hunters and scientists who taught fish how to walk to nonagenarian explorers of the deep sea. Woven throughout are vignettes of Helen's own aquatic explorations, from eerie nighttime dives with glowing fish and up-close encounters with giant manta rays, to floating in the middle of a swirling shoal being watched by thousands of inquisitive eyes. As well as being a rich and entertaining read, this book will inspire readers to think again about these animals and the seas they inhabit, and to go out and appreciate the wonders of fish, whether through the glass walls of an aquarium or, better still, by gazing into the fishes' wild world and swimming through it.

All communities are teeming with energy, spirit, and knowledge, and Spiral to the Stars taps into and activates this dynamism to discuss Indigenous community planning from a Mvskoke perspective. This book poses questions about what community is, how to reclaim community, and how to embark on the process of envisioning what and where the community can be. Geographer Laura Harjo demonstrates that Mvskoke communities have what they need to dream, imagine, speculate, and activate the wishes of ancestors, contemporary kin, and future relatives—all in a present temporality—which is Indigenous futurity. Organized around four methodologies—radical sovereignty, community knowledge, collective power, and emergence geographies—Spiral to the Stars provides a path that departs from traditional community-making strategies, which are often extensions of the settler state. Readers are provided a set of methodologies to build genuine community relationships, knowledge, power, and spaces for themselves. Communities don’t have to wait on experts because this book helps them activate their own possibilities and expertise. A detailed final chapter provides participatory tools that can be used in workshop settings or one on one. This book offers a critical and concrete map for community making that leverages Indigenous way-finding tools. Mvskoke narratives thread throughout the text, vividly demonstrating that theories come from lived and felt experiences. This is a must-have book for community organizers, radical pedagogists, and anyone wishing to empower and advocate for their community.

A fascinating journey with the sea creature that has captured human imagination for thousands of years Poseidon's Steed trails the seahorse through secluded waters across the globe in a kaleidoscopic history that mirrors man's centuries-old fascination with the animal, sweeping from the reefs of Indonesia, through the back streets of Hong Kong, and back in time to ancient Greece and Rome. Over time, seahorses have surfaced in some unlikely places. We see them immortalized in the decorative arts; in tribal folklore, literature, and ancient myth; and even on the pages of the earliest medical texts, prescribed to treat everything from skin complaints to baldness to flagging libido. Marine biologist Helen Scales eloquently shows that seahorses are indeed fish, though scientists have long puzzled over their exotic anatomy, and their very strange sex lives — male seahorses are the only males in the animal world that experience childbirth! Our first seahorse imaginings appeared six thousand years ago on cave walls in Australia. The ancient Greeks called the seahorse hippocampus (half-horse, half-fish) and sent it galloping through the oceans of mythology, pulling the sea god Poseidon's golden chariot. The seahorse has even been the center of a modern-day international art scandal: A two-thousand-year-old winged seahorse brooch was plundered by Turkish tomb raiders and sold to the Metropolitan Museum of Art in New York. A book that is as charming as the seahorse itself, Poseidon's Steed brings to life an aquatic treasure. Seahorses lead quiet lives, tucked away out of sight on the seafloor. It is rare to catch a glimpse of a seahorse in its natural habitat. But even if few have seen one live, these exotic, seemingly prehistoric creatures exist quite vividly in our imaginations and they have mesmerized scientists, artists, and storytellers throughout time with their otherworldly rarity. Poseidon's Steed is a sweeping journey that takes us from the coral reefs and seagrass meadows of Indonesia where many seahorses makes their natural habitat to the back streets of Hong Kong where a thriving black market seahorse trade is concealed. Throughout history, seahorses have surfaced in some unexpected places and Scales also follows the seahorse back in time, from our most rudimentary seahorse imaginings six thousand years ago on cave walls in Australia, to the myths of ancient Greece. Scientists have long puzzled over seahorses' unusual anatomy and their very strange sex lives. And male seahorses are the only males in the animal world that experience childbirth! Seahorses are not what scientists call a "keystone" species. They rely on a healthy ocean to survive, but the marine ecosystem does not rely on them. But their delicate beauty reminds us that we rely on the seas not only to fill our dinner plates, but also to feed our imaginations.

From the tiny twisted biological molecules to the gargantuan curling arms of many galaxies, the physical world contains a startling repetition of spiral patterns. Today, researchers have a keen interest in identifying, measuring, and defining these patterns in scientific terms. Spirals play an important role in the growth processes of many biological forms and organisms. Also, through time, humans have imitated spiral motifs in their art forms, and invented new and unusual spirals which have no counterparts in the natural world. Therefore, one goal of this multiauthored book is to stress the conspicuous role that spirals play in science, and to show the reader how to create such spirals using a computer. Another goal is to show how simple mathematical formulas can reveal magnificent shapes and images. This interdisciplinary book revolves around a common theme, spiral symmetry, and is intended for scientists, humanists, and interested laypeople.

Forget everything you thought you knew about unicorns and maidens... A unicorn is not supposed to survive the death of its rider, but Majherri did. Now he is a pariah, mistrusted by the Greater Herd. To reclaim his lost honor and status, he will entrust the remnants of his life to a new human female while unraveling the mystery of his continued existence. Kayleigh Reese is not Battle Maiden material. She's three years older than any other recruit and has enjoyed a peaceful, nomadic life working with her artist mother. The rigors of joining the High-King's elite unicorn cavalry are clearly not for her. Now, with a bond to Majherri, she must overcome her mother's disapproval, the ire of her commanding officer and fellow trainees, and, most importantly, the secrets of her unicorn's past if she is to become a legendary warrior. To prevail, they must quickly come together as a team and unlock the powerful and dangerous magic inside them.
