The notion of a living world is one of humanity’s oldest beliefs. Though once scorned by many scientists, the concept of Earth as a vast interconnected living system has gained acceptance in recent decades. Life not only adapts to its surroundings – it also shapes them in dramatic and enduring ways. Over billions of years, life transformed a lump of orbiting rock into our cosmic oasis, breathing oxygen into the atmosphere, concocting the modern oceans, and turning rock into fertile soil. Life is intertwined with Earth’s capacity to regulate its climate and maintain balance.

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.

In 2017, author Shanna Swan and her team of researchers completed a major study. They found that over the past four decades, sperm levels among men in Western countries have dropped by more than 50 percent. They came to this conclusion after examining 185 studies involving close to 45,000 healthy men. The result sent shockwaves around the globe - but the story didn’t end there.

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.

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.

These days, probiotic yogurt and other "gut-friendly" foods line supermarket shelves. But what's the best way to feed our all-important microbiome - and what is a microbiome, anyway? In this engaging book, science journalist Katherine Harmon Courage investigates these questions, presenting a deep dive into the ancient food traditions and the latest research for maintaining a healthy gut.

This volume, aimed at the general audience, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies.

In the 1830s, a young naturalist called Charles Darwin set out as part of a survey expedition on the HMS Beagle. Darwin collected fossils and different species of plants and animals, and made many detailed observations that inspired him to develop what once seemed an absolutely crazy idea - a theory that would change the world.

What does it take to raise a great dog? This was the question that husband-and-wife team Brian Hare and Vanessa Woods hoped to answer when they enrolled one hundred and one puppies in the Duke Puppy Kindergarten. With the help of a retired service dog named Congo, Brian, Vanessa, and their team set out to understand the secrets of the puppy mind: What factors might predict whether a puppy will grow up to change someone’s life?

Life began with the hydrogenation of CO2, and this is the process we must return to in order to heal the planet. Ground-breaking ongoing research into bacterial processes means our knowledge of bacterial processes is ever-expanding, and we can harness this new knowledge to develop a parallel carbon economy using engineered bacteria for fuel, food, and materials. This would enable rewilding on a vast scale, with the small land footprint of bacterial technologies solving the current conflict in land use between farming and fuel and materials production.

Again and again, microbes have shaped our health, our genetics, our history, our culture, our politics, even our religion and ethics. This book reveals much that scientists and cultural historians have learned about the pervasive interconnections between infectious microbes and humans. It also considers what our ongoing fundamental relationship with infectious microbes might mean for the future of the human species.

Brigit Strawbridge Howard was shocked the day she realized she knew more about the French Revolution than she did about her native trees. And birds. And wildflowers. And bees. The thought stopped her — quite literally — in her tracks. But that day was also the start of a journey, one filled with silver birches and hairy-footed flower bees, skylarks, and rosebay willow herb, and the joy that comes with deepening one’s relationship with place.

We are surrounded by big claims for how to enhance our immunity. But the one thing the science is clear on is that everyone's immune system is entirely unique. So how do we tell the myths from the facts? And is there anything we can actually do to benefit our immune health? World-leading immunologist Daniel M. Davis has the answers in this truly authoritative and highly accessible, myth-busting guide to the effects of stress, age, exercise, weight, nutrition, sleep and mental health on our immune health.

Interweaving her own first-hand experiences in the field with the compelling research of premier scientists, Goodall illuminates the heroic efforts of dedicated environmentalists and the truly critical need to protect the habitats of these beloved species. At once a celebration of the animal kingdom and a passionate call to arms, Hope for Animals and Their World presents an uplifting, hopeful message for the future of animal-human coexistence.

Why do people believe bunk? And what causes them to embrace such pseudoscientific beliefs and practices? Noted skeptic Massimo Pigliucci sets out to separate the fact from the fantasy in this entertaining exploration of the nature of science, the borderlands of fringe science, and - borrowing a famous phrase from philosopher Jeremy Bentham - the nonsense on stilts.

Bacteria form a fundamental branch of life. They are the oldest forms of life and the most prolific of all living organisms, inhabiting every part of the Earth's surface, its ocean depths, and even such inhospitable places as boiling hot springs. In this Very Short Introduction, bacteriologist Sebastian Amyes explores the nature of bacteria, their origin and evolution, bacteria in the environment, and bacteria and disease.

Piping Hot Bees and Boisterous Buzz-Runners takes listeners inside a world seldom seen even by beekeepers, shedding light on twenty of the most compelling mysteries of honey bee behavior.

Analyzing brainwaves, the imperceptible waves of electricity surging across your scalp, has been possible for nearly a century. But only now are neuroscientists becoming aware of the wealth of information brainwaves hold about a person’s life, thoughts, and future health. From the moment a reclusive German doctor discovered waves of electricity radiating from the heads of his patients in the 1920s, brainwaves have sparked astonishment and intrigue, yet the significance of the discovery and its momentous implications have been poorly understood.

Everywhere there are characteristics of animals that do not want to fit into the theory of evolution anywhere. And man? Are we really the most adapted life-form on this planet? Today, more and more scientists who contradict the previous theory of evolution speak out. The theory fits the changes within the species, but it can no longer be reconciled with the inner workings of the cell. Some other influence that has so far escaped us is affecting evolution. It is called "Intelligent Design." Intelligent planning is suspected behind this.

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.
