Ignác Semmelweis is remembered for the now-commonplace notion that doctors must wash their hands before examining patients. In mid-19th century Vienna, however, this was a subversive idea. With deaths from childbed fever exploding, Semmelweis discovered that doctors themselves were spreading the disease. While his simple reforms worked immediately - childbed fever in Vienna all but disappeared - they brought down upon Semmelweis the wrath of the establishment, and led to his tragic end.

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.

‘What is it like to be a bat?’, the philosopher Thomas Nagel famously asked concerning consciousness. For biologist Martin Stevens, the question forms the starting point of an exploration of animal senses. In this enthralling account, we learn not only of the wonder of animal senses, but how they work and how scientists go about investigating them. And, throughout, we consider how these senses came to be.

John Parrington draws on the latest research on the human brain to show how it differs strikingly from those of other animals in its structure and function at a molecular and cellular level. And he argues that this 'shift', enlarging the brain, giving it greater flexibility and enabling higher functions such as imagination, was driven by tool use, but especially by the development of one remarkable tool - language.

In this Very Short Introduction audiobook, marine biologist Philip Mladenov provides an accessible and up-to-date overview of marine biology, offering a tour of marine life and marine processes that ranges from the unimaginably abundant microscopic organisms that drive the oceans' food web to the apex predators that we exploit for food; from polar ocean ecosystems to tropical coral reefs; and from the luxurious kelp beds of the coastal ocean to deep-ocean hydrothermal vents where life exists without the energy of the sun.

Morange covers everything from the first cell theory to the origins of the concept of ecosystems, and offers perspectives on areas that are often neglected by historians of biology, such as ecology, ethology, and plant biology. He highlights the contributions of technology, the important role of hypothesis and experimentation, and the cultural contexts in which some of the most breathtaking discoveries in biology were made. Unrivaled in scope and written by a world-renowned historian of science, A History of Biology is an ideal introduction for students and experts alike.

Genomics has transformed the biological sciences. From epidemiology and medicine to evolution and forensics, the ability to determine an organism's complete genetic makeup has changed the way science is done and the questions that can be asked of it. John Archibald explores the science of genomics and its rapidly expanding toolbox. Archibald tells us how the field of genomics is on the cusp of another quantum leap; the implications for science and society are profound.

The last decade has seen an explosion of urban beekeeping in the US, Canada, and Europe, a well-intentioned response to perceived threats to the global honey bee population. Many thousands of people have taken up this seemingly environmentally friendly hobby, tending backyard and rooftop hives (or paying a company to do so) and encouraging honey bees to make honey and pollinate flowers. What could be wrong with that? Quite a lot, in fact. In The Honey Trap, scientist and author Dana Church demonstrates that despite reports to the contrary, honey bees are nowhere near extinction.

Biomedical researcher Professor John Tregoning tells the unlikely story of how, against all odds, we manage to stay alive. Taking an organ-by-organ tour of the human body, Tregoning embarks on his own experimental quest, testing "life-extending" diets and exercise regimes to separate fact from fad. Exploring the multitude of ways our bodies can kill us, from inherited genetic conditions, through heart attacks, arrythmias and angina, onto the delicate workings of the brain, Live Forever? offers compelling insight into how our bodies work, how we can best look after them.

Wir sind ohne Zweifel ein Wunder der Evolution. Unsere außergewöhnlichen körperlichen Eigenschaften und unsere Innovationen haben unsere Zivilisationen geschaffen. Aber wir sind auch zutiefst fehlerbehaftet. Unsere Körper brechen, ersticken und versagen, ob wir nun Könige oder Bauern sind. Krankheiten durchkreuzen unsere kühnsten Pläne, unsere Psyche ist die Ursache für schreckliche Entscheidungen in Krieg und Frieden. Diese faszinierende Widersprüchlichkeit ist die Essenz des Menschseins: die Summe unserer Schwächen und unserer Stärken, zwischen denen sich die Historie bewegt.

As dramatic as The Double Helix and as absorbing as The Soul of a New Machine, Natural Obsessions explores the advanced reaches of molecular biology, the nature of the human cell, and the genes that control cancer. It unforgettably portrays some of the best young scientists in the world, the rewards and discouragements of scientific research, and the very process of scientific inquiry.

Natalie Angier knows all that scientists know—and sometimes more—about the power of symmetry in sexual relations, about the brutal courting habits of dolphins, about the grand deceit of orchids, about the impact of female and male preferences on evolution. She knows how scientists go about their work, and she describes their ways, their visions, and their arguments. Perhaps most poignantly, she understands the complexities and the sad necessity of death.

This highly understandable and entertaining book distils best practice research on science communication into accessible chapters, supported by case studies and examples. With practical advice on everything from messages and metaphors to metrics and ethics, you will learn what the public think about science and why, and how to shape scientific research into a story that will influence beliefs, behaviours and policies.

By the time a baby is born, its brain is equipped with billions of intricately crafted neurons wired together through trillions of interconnections to form a compact and breathtakingly efficient supercomputer. Zero to Birth takes you on an extraordinary journey to the very edge of creation, from the moment of an egg's fertilization through each step of a human brain's development in the womb—and even a little beyond. As W. A. Harris guides you through the process of how the brain is built, he takes up the biggest questions that scientists have asked about the developing brain.

Biologist Rob Dunn's Every Little Thing is the story of man's obsessive quest to catalog life, from nanobacteria to new monkeys. In the tradition of E. O. Wilson, this engaging and fascinating work of popular science follows humanity's unending quest to discover every living thing in our natural world-from the unimaginably small in the most inhospitable of places on earth to the unimaginably far away in the unexplored canals on Mars.

In this Very Short Introduction, Paul B. Wignall looks at the causes and nature of extinctions, past and present, and the factors that can make a species vulnerable. Summarizing what we know about all of the major and minor extinction events, he examines some of the greatest debates in modern science, such as the relative role of climate and humans in the death of the Pleistocene megafauna, including mammoths and giant ground sloths, and the roles that global warming, ocean acidification, and deforestation are playing in present-day extinctions.

After 25 years on a farm in the Ozarks, award-winning writer and naturalist Sue Hubbell moved to a small town on the coast of Maine. There, in the pools, tides, and thickets, she found a vast array of creatures that aroused her considerable curiosity. Join Hubbell on a unique tour of the world of invertebrates. From humpbacked camel crickets to glow worms, from horseshoe crabs to elegantly-furred sea mice, Hubbell offers vivid descriptions and fascinating details about these superb examples of survival.

From rainforests to deserts, mountains to plains, the sea to the sky, animals raise their voices in an eclectic and thrilling chorus. This collection celebrates the unique calls of the keel-billed toucan, the morning roar of the Guatemalan howler monkey, the seriously social laughing of the spotted hyena Guatemalan coatimundi, the honk of the courtship-crazed hammerhead bat, sophisticated conversation from the Central African forest elephant, the subtle bellow of the great plains bison, and many more intriguing sounds.
