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.

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

The first-ever comprehensive history of Beringia, the Arctic land and waters stretching from Russia to Canada, Floating Coast breaks away from familiar narratives to provide a fresh and fascinating perspective on an overlooked landscape. The unforgiving territory along the Bering Strait had long been home to humans - the Inupiat and Yupik in Alaska, and the Yupik and Chukchi in Russia - before Americans and Europeans arrived with revolutionary ideas for progress.

How did Civil War soldiers endure the brutal and unpredictable existence of army life during the conflict? This question is at the heart of Peter S. Carmichael's sweeping new study of men at war.

The Transcendentalists and Their World offers a fresh view of the thinkers whose outsized impact on philosophy and literature would spread from tiny Concord to all corners of the earth. Ralph Waldo Emerson, Henry David Thoreau, Nathaniel Hawthorne, and the Alcotts called this New England town home, and Thoreau drew on its life extensively in his classic Walden. Concord was a community in ferment, whose small, ordered society was unsettled through the expansive forces of capitalism and democracy.

Bill Bryson and his family live in a Victorian parsonage in a part of England where nothing of any great significance has happened since the Romans decamped. Yet one day, he began to consider how very little he knew about the ordinary things of life as he found it in that comfortable home. To remedy this, he formed the idea of journeying about his house from room to room to “write a history of the world without leaving home.”

In The Butchering Art, the historian Lindsey Fitzharris reveals the shocking world of 19th-century surgery on the eve of profound transformation. She conjures up early operating theaters - no place for the squeamish - and surgeons, working before anesthesia, who were lauded for their speed and brute strength. They were baffled by the persistent infections that kept mortality rates stubbornly high. A young, melancholy Quaker surgeon named Joseph Lister would solve the deadly riddle and change the course of history.

This is a thrilling historical account of the worst cholera outbreak in Victorian London and a brilliant exploration of how Dr. John Snow's solution revolutionized the way we think about disease, cities, science, and the modern world.

In The Poisoner's Handbook, Blum draws from highly original research to track the fascinating, perilous days when a pair of forensic scientists began their trailblazing chemical detective work, fighting to end an era when untraceable poisons offered an easy path to the perfect crime.

David Oshinsky, whose last book, Polio: An American Story, was awarded a Pulitzer Prize, chronicles the history of America's oldest hospital and in so doing also charts the rise of New York to the nation's preeminent city, the path of American medicine from butchery and quackery to a professional and scientific endeavor, and the growth of a civic institution.

In 40 years, Earth's population will reach 10 billion. Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups - Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin.

Thousands of American soldiers are returning from the battlefields of Iraq and Afghanistan with severe wounds from chemical war. They are not the victims of ruthless enemy warfare, but of their own military commanders. These soldiers, afflicted with rare cancers and respiratory diseases, were sickened from the smoke and ash swirling out of the "burn pits" where military contractors incinerated mountains of trash, including old stockpiles of mustard and sarin gas, medical waste, and other toxic material.

Thomas Edison was born into a hard-working but attentive family. He struggled in school and became deaf at an early age. Born on February 11, 1847, Edison would become, arguably, the best-known American inventor of all time. His invention of the light bulb was one of more than 1,000 patents he held during his lifetime. Others included the phonograph, the electrical grid, and motion pictures. His work changed the way we see and hear the world around us.

The War on Cancer was run by leaders of industries that made cancer-causing products and sometimes also profited from drugs and technologies for finding and treating the disease. Filled with compelling personalities and never-before-revealed information, The Secret History of the War on Cancer shows how we began fighting the wrong war, with the wrong weapons, against the wrong enemies, a legacy that persists to this day.

One of New Jersey’s seemingly innumerable quiet seaside towns, Toms River became the unlikely setting for a decades-long drama that culminated in 2001 with one of the largest legal settlements in the annals of toxic dumping. A town that would rather have been known for its Little League World Series champions ended up making history for an entirely different reason: a notorious cluster of childhood cancers scientifically linked to local air and water pollution.
