The heart usually comes up in a Biology course. After all, it is one the most important organs; it constantly maintains life through the circulation of blood to the respiring cells. It also though, comes up a lot in people's lives; unfortunately this often takes the form of heart disease, your own, or someone you love or know. Quite a lot of people have trouble understanding how the heart works, it is a miracle of engineering and structural design and it takes a bit of effort to get to grips with it. What I want to do in this short book is explain clearly how the heart works and why this ...

In “The Molecular Polypharmacology of Essential Oils: Targets, Pathways, and Mechanisms,” renowned natural medicine expert Dr. Scott A. Johnson takes you on a revolutionary journey into the molecular science behind essential oils. With decades of research distilled into this comprehensive guide, you'll gain an unprecedented look at how essential oils work—not just anecdotally, but at the cellular and molecular levels. This powerful book explores the inherent polypharmacology of essential oils—their natural ability to influence multiple targets and mechanisms simultaneously—due to ...

Humans are remarkable beings. We have mastered flight, cracked the genetic code, developed quantum mechanics and democracy, been to the moon, and may soon become a multi-planetary species. Yet, despite these unparalleled achievements, we can still be...pretty stupid.

As a tutor of Biology of about 20 years experience I quite often came across students who were struggling with the basics. Most often the subject of the basic biological molecules; proteins, carbohydrates and lipids, was causing them some confusion. Admittedly, for biology students who don't study chemistry, this subject can be a challenge. So what I have done in this book is give a summary of the most important points about these molecule groups in the easily understandable format, of a series of questions and answers. I have also included a chapter of key words, that I explain, before the...

The discovery of the structure of DNA, in 1953, by Watson and Crick, was arguably the most important discovery in biology of that century; and certainly one of the most important discoveries in science, ever. Around sixty years later; we have already cracked the human genome (we know the nature of all codes within the DNA in human beings) and can sequence DNA and copy DNA very quickly. Our knowledge of the evolutionary relationships between living things has been greatly improved by knowing the similarities and differences of their genes. Here are a few astonishing facts about DNA that have...

With a tone that blends science, storytelling, and just the right amount of awe, author Serena Quillan dives deep into the biology, behaviour, and bizarre adaptations of this elusive cephalopod. This isn’t just another marine creature book—this is a guided expedition into a world most humans will never experience, revealing facts so surprising they’ll challenge what you think you know about life on Earth.

It might be their large, strangely human eyes or their dog-like playfulness, but seals have long captured people's interest and affection, making them the perfect candidate for an environmental cause, as well as the subject of decades of study. Alix Morris spends a year with these magnetic creatures and brings them to life on the page, season by season, as she learns about their intelligence, their relationships with each other, their ecosystems, and the changing climate.

What is the actual basis of terms such as "goal," "function," and "for the sake of"? Can these teleological concepts be validly applied to non-conscious biological processes such as the heartbeat, plant growth, and cellular metabolism? Does the behavior of any inanimate objects, natural or man-made, qualify as goal-directed? To resolve these issues, Harry Binswanger provides a unique approach combining factual and epistemological considerations. If human purposeful action is the paradigm case of goal-directed action, then regarding a non-purposeful process as goal-directed means taking it ...

AIDS, Malaria, Cholera, Tuberculosis and Cystic Fibrosis: this book is about explaining what causes these diseases and what cures or treatments are available. As they represent different types of disease in each case; I believe someone reading this will gain the understanding of not only AIDS, malaria, cholera, TB and cystic fibrosis; but also many other diseases that have the same or similar basis. This book will particularly benefit students of biology and medicine; but is written in understandable language for non-students; who may just have an interest in these diseases. I hope that by ...

In The Animal and The Thinker, the world-leading, pioneering neuroscientist John Duncan explains that each of us is not just one person – we are two. On one side are our animal instincts, built on the sophisticated needs of human life through evolution, but struggling to navigate the complexity of modern life. On the other side is our rational brain which calculates and cogitates, but is often helpless in the face of bigger questions of meaning and purpose.

The Anti-Catastrophe League, informed by the author’s experience of working in the field of what is known as existential risk, tells the story of a species that is working out how to defuse several bombs at once. From ancient risks to very modern apocalypses, the book charts the imminent dangers to the human race and introduces listeners to the groups of scientists, eccentrics, diplomats and visionaries who are doing everything in their considerable power to prevent the worst from befalling us.

This book explains the features of the basic unit of Biology; the cell. It is written for Biology students and explains the cell, its structures and functions and the significance of these; in a question and answer format that is easy to work through. It also has exam questions and answers to help students with their end of course tests. This is a useful book for any Biology student who wants to understand the subject properly.

In this book I aim to give you a summary of the main aspects of viruses: their structure, uses, health impact and evolutionary origin. The main points are made in a clear and easily understood question and answer format. The book starts with a few interesting facts to whet your appetite and then explains the main scientific terms so you know them before you read the main aspects. We are all affected by viruses regarding our health alone, on top of this they are a fascinating area of biology to study. The HIV, swine flu and Ebola epidemics have only served to illustrate the impact that ...
