Our sense of smell - or olfaction as it is technically known - is our most enigmatic sense. It can conjure up memories, taking us back to very specific places and emotions, whilst powerful smells can induce strong feelings of hunger or nausea. In the animal kingdom smell can be used to find food, a mate, or a home; to sense danger; and to send and receive complex messages with other members of a species. Yet despite its fundamental importance in our mental life and in the existence of all animals, our scientific understanding of how smell works is limited.

For all that science knows about the living world, notes David P. Barash, there are even more things we don't know, genuine evolutionary mysteries that perplex the best minds in biology. Paradoxically, many of these mysteries are very close to home, involving some of the most personal aspects of being human. Homo Mysterious examines a number of these evolutionary mysteries, exploring things we don't yet know about ourselves, laying out the best current hypotheses, and pointing toward insights that scientists are just beginning to glimpse.

Professor Jim Davies's fascinating and highly accessible book, Riveted, reveals the evolutionary underpinnings of why we find things compelling. Drawing on work from philosophy, anthropology, religious studies, psychology, economics, computer science, and biology, Davies offers a comprehensive explanation to show that in spite of the differences between the many things that we find compelling, they have similar effects on our minds and brains.

It seems likely that scientists will someday discover how life can emerge on habitable planets like the early Earth and Mars. In Origin of Life: What Everyone Needs to Know, David W. Deamer has written a comprehensive guide to the origin of life that is organized in three sections.

A pioneering exploration of olfaction that upsets settled notions of how the brain translates sensory information.

The time to rethink degenerative brain disorders has come. With no biological boundaries between neurodegenerative diseases, illnesses such as Parkinson's and Alzheimer's result from a large spectrum of biological abnormalities, hampering effective treatment. Acclaimed neurologist Dr. Alberto Espay and Parkinson's advocate Benjamin Stecher present compelling evidence that these diseases should be targeted according to genetic and molecular signatures rather than clinical diagnoses.

Florapedia is an eclectic A-Z compendium of botanical lore. With more than 100 enticing entries - on topics ranging from achlorophyllous plants that use a fungus as an intermediary to obtain nutrients from other plants to zygomorphic flowers that admit only the most select pollinators - this collection is a captivating journey into the realm of botany. Writing in her incomparably engaging style, Carol Gracie discusses remarkable plants from around the globe, botanical art and artists, early botanical explorers, ethnobotanical uses of plants, botanical classification, and more.

Santiago Ramon y Cajal is likely the most important figure in the history of biology you've never heard of. Along with Darwin and Pasteur, he ranks among the most brilliant and original biologists of the nineteenth century, and his discoveries have done for our understanding of the human brain what the work of Galileo and Sir Isaac Newton did for our conception of the physical universe. Benjamin Ehrlich's The Brain in Search of Itself is the first major biography in English of this figure, whose scientific odyssey mirrored the rocky journey of his beloved homeland of Spain.

The story of the "Lentil Underground" begins on a 280-acre homestead rooted in America's Great Plains: the Oien family farm. Forty years ago, corporate agribusiness told small farmers like the Oiens to "get big or get out." But 27-year-old David Oien decided to take a stand, becoming the first in his conservative Montana county to plant a radically different crop: organic lentils. Unlike the chemically dependent grains American farmers had been told to grow, lentils make their own fertilizer and tolerate variable climates, so their farmers aren't beholden to industrial methods.

John Muir was an early proponent of a view we still hold today—that much of California was pristine, untouched wilderness before the arrival of Europeans. But as this book demonstrates, what Muir was really seeing when he admired the grand vistas of Yosemite and the gold and purple flowers carpeting the Central Valley were the fertile gardens of the Sierra Miwok and Valley Yokuts Indians, modified and made productive by centuries of harvesting, tilling, sowing, pruning, and burning.

What is it like to be a dog? A bat? Or a dolphin? To find out, neuroscientist Gregory Berns and his team began with a radical step: they taught dogs to go into an MRI scanner - completely awake. They discovered what makes dogs individuals with varying capacities for self-control, different value systems, and a complex understanding of human speech. And dogs were just the beginning. In What It's Like to Be a Dog, Berns explores the fascinating inner lives of wild animals from dolphins and sea lions to the extinct Tasmanian tiger.

What defines who we are? For decades, the answer has seemed obvious: our genes, the "blueprint of life." In The Master Builder, biologist Alfonso Martinez Arias argues we've been missing the bigger picture. It's not our genes that define who we are, but our cells.

Most of us are familiar with probiotics added to milk or yogurt to improve gastrointestinal health. In this ambitious and original work, Jamie Lorimer offers a sweeping overview of diverse probiotic approaches and an insightful critique of their promise and limitations.

In November 2018, the world was shocked to learn that two babies had been born in China with DNA edited while they were embryos - as dramatic a development in genetics as the cloning of Dolly the sheep was in 1996. In this book, Hank Greely, a leading authority on law and genetics, tells the fascinating story of this human experiment and its consequences. Greely explains what Chinese scientist He Jiankui did, how he did it, and how the public and other scientists learned about and reacted to this unprecedented genetic intervention.

With vivid, observant reporting, veteran environmental journalist Fred Pearce transports listeners to the remote cloud forests of Ecuador, the remains of a forest civilization in Nigeria, a mystifying mountain peak in the middle of the Atlantic Ocean, and the boreal forests of western Canada and the United States, where devastating wildfires are linked to suppressing the natural fire cycles of forests and the maintenance practices of Indigenous peoples. Throughout the book, Pearce interviews the people who traditionally live in forests.

Here is the extraordinary story of the unfolding of life on Earth, told by Michael J. Benton, a world-renowned authority on biodiversity. Ranging over four billion years, Benton weaves together the latest findings on fossils, earth history, evolutionary biology, and many other fields to highlight the great leaps that enabled life to evolve from microbe to human - big breakthroughs that made whole new ways of life possible - including cell division and multicellularity, hard skeletons, the move to land, the origin of forests, the move to the air.

For many of us, the buzzing of a bee elicits panic. But the next time you hear that low droning sound, look closer: the bee has navigated to this particular spot for a reason using a fascinating set of tools. What a Bee Knows: Exploring the Thoughts, Memories, and Personalities of Bees invites us to follow bees' mysterious paths and experience their alien world.

In Of Orcas and Men, a marvelously compelling mix of cultural history, environmental reporting, and scientific research, David Neiwert explores an extraordinary species and its occasionally fraught relationship with human beings. Beginning with their role in myth and contemporary culture, Neiwert shows how killer whales came to capture our imaginations and brings to life the often-catastrophic environmental consequences of that appeal.

Amanda Lewis was an overachieving, burned-out book editor most familiar with trees as dead blocks of paper. A dedicated "indoorswoman," she could barely tell a birch from a beech. But that didn't stop her from pledging to visit all of the biggest trees in British Columbia, a Canadian province known for its rugged terrain and gigantic trees.

Ever since Carl Linnaeus's binomial system of scientific names was adopted in the 18th century, scientists have been eponymously naming organisms in ways that both honor and vilify their namesakes. This charming, informative, and accessible history examines the fascinating stories behind taxonomic nomenclature, from Linnaeus himself naming a small and unpleasant weed after a rival botanist to the recent influx of scientific names based on pop-culture icons-including David Bowie's spider, Frank Zappa's jellyfish, and Beyonce's fly.
