Titoli in Biologia

The term "gender" was first distinguished from "sex" in the 1950s when psychologists began to discuss the idea of "gender roles", behaviors and responsibilities given to people by a society rather than flowing from their biology. Since then, leaders across disciplines have sought to better understand the roles of biology, psychology, and culture on gender. New language has emerged alongside rich scientific inquiry and research. Increased visibility of transgender and nonbinary communities has brought awareness to a range of gender diverse experiences....

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 this sweeping history of more than 3,000 years, beginning with ancient Egypt, scientist Marcus Byrne and writer Helen Lunn capture the diversity of dung beetles and their unique behavior patterns. Dung beetles' fortunes have followed the shifts from a world dominated by a religion that symbolically incorporated them into some of its key concepts of rebirth, to a world in which science has largely separated itself from religion and alchemy.

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.

Evolution is one of the most important processes in life. It not only explains the detailed history of life on earth, but its scope also extends into many aspects of our own contemporary behavior - who we are and how we got to be here, our psychology, our cultures - and greatly impacts modern advancements in medicine and conservation biology. Perhaps its most important claim for science is its ability to provide an overarching framework that integrates the many life sciences into a single unified whole. Yet, evolution has been, and continues to be, regarded with suspicion by many.

‘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.

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.

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.

What is our immune system, and how does it work? A vast array of cells, proteins and chemicals spring into action whenever our bodies are damaged, but immunity is not something you can see, touch, or feel. It can fight off malicious bacteria and viruses, locate cancerous growths, and even rewire our brains—but sometimes our own tissues can get caught in its crossfire, with catastrophic consequences. Humans may be the most disease-ridden animals on the planet. Professor John Trowsdale shows how the immune system protects us, and how our bodies invest huge resources to keep it running.

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.

He aquí un libro revolucionario cuya importancia ha sido comparada a la de El origen de las especies de Darwin. El biólogo Rupert Sheldrake afirma que la probabilidad de ocurrencia de un fenómeno aumenta proporcionalmente a su ocurrencia pasada. Cuando los químicos, por ejemplo, consiguen...

"Al igual que La vida de las abejas, de la cual todas las afirmaciones que se han hecho han sido reconocidas como exactas por los especialistas, La vida de las termitas no es una biografía novelesca, tan de moda en estos momentos. He permanecido fiel al principio que me ha guiado en la obra...

The open ocean, far from the shore and miles above the seafloor, is a vast and formidable habitat that is home to the most abundant life on our planet, from giant squid and jellyfish to anglerfish with bioluminescent lures that draw prey into their toothy mouths. Into the Great Wide Ocean takes listeners inside the peculiar world of the seagoing scientists who are providing tantalizing new insights into how the animals of the open ocean solve the problems of their existence.

Many undergraduate students choose a science degree but are not aware of how science and research work in the real world. This book explains how scientific research is conceived, carried out and analyzed. It outlines how research findings are constantly evolving and why that is exciting and important. Students using this textbook will learn how to design experiments, explain their data, and analyze and interpret the work of others.

For billions of years, microbes have produced and consumed greenhouse gases that regulate global temperature and in turn other aspects of our climate. The balance of these gases maintains Earth's habitability. Methane, a greenhouse gas produced only by microbes, may have kept Earth out of a deep freeze billions of years ago. Likewise, variations in carbon dioxide, another greenhouse gas released by microbes and other organisms, help to explain the comings and goings of ice ages over the last million years. Now we face a human-made climate crisis with drastic consequences.

Though you may not be able to see them with the naked eye, parasites inhabit our everyday lives. From headlice to bird droppings, litterboxes to unfiltered water, you have brushed up against the most common way of life on our planet. In this unique book, John Janovy Jr., one of the world's preeminent experts on parasites, reveals what can humans learn from the most reviled yet misunderstood animals on Earth: lice, tapeworms, flukes, and maggots that can eat a lizard from the inside, and how these lessons help us negotiate our own complicated world.
