Domesticated since the dawn of man, pigeons have been used as crucial communicators in war by every major historical superpower from ancient Egypt to the United States and are credited with saving thousands of lives. They have been worshipped as fertility goddesses and revered as symbols of peace. Charles Darwin relied heavily on pigeons to help formulate and support his theory of evolution. Yet today they are reviled as "rats with wings."

Making sense of sound is one of the hardest jobs we ask our brains to do. In Of Sound Mind, Nina Kraus examines the partnership of sound and brain, showing for the first time that the processing of sound drives many of the brain's core functions. Our hearing is always on - we can't close our ears the way we close our eyes - and yet we can ignore sounds that are unimportant. We don't just hear; we engage with sounds. Kraus explores what goes on in our brains when we hear a word - or a chord, or a meow, or a screech.

They destroy plant diseases. They break down toxins. They plough the earth. They transform forests. They’ve survived two mass extinctions, including the one that wiped out the dinosaur. Not bad for a creature that’s deaf, blind, and spineless. Who knew that earthworms were one of our planet’s most important caretakers? Or that Charles Darwin devoted his last years to studying their remarkable achievements?

La biodiversidad: El ciudadano urbano, ajeno a los ritmos naturales, tiene la impresión de haberse independizado de la vida silvestre. La realidad es otra. En el día a día, utilizamos multitud de productos cuyo origen está en las plantas y animales silvestres. En las selvas tropicales se encierra la mayor diversidad biológica del planeta.

In 2020, an invisible germ - a virus - wholly upended our lives. We're most familiar with the viruses that give us colds or Covid-19. But viruses also cause a vast range of other diseases, including one disorder that makes people sprout branch-like growths as if they were trees. Viruses have been a part of our lives for so long that we are actually part virus: the human genome contains more DNA from viruses than our own genes. Meanwhile, scientists are discovering viruses everywhere they look: in the soil, in the ocean, even in deep caves miles underground.

Mary Anning was only 12 years old when, in 1811, she discovered the first dinosaur skeleton - of an ichthyosaur - while fossil hunting on the cliffs of Lyme Regis, England. Until Mary's incredible discovery, it was widely believed that animals did not become extinct.

One of the most complicated and advanced computers on Earth can't be purchased in any store. This astonishing device, responsible for storing and retrieving vast quantities of information that can be accessed at a moment's notice, is the human brain. How does such a dynamic and powerful machine make memories, learn a language, and remember how to drive a car? What habits can we adopt in order to learn more effectively throughout our lives? The answers to these questions are merely the tip of the iceberg in The Learning Brain.

Does your dog get sad when you leave for the day? Does your cat purr because she loves you? Do bears attack when they’re angry? You can’t very well ask them. In fact, scientists haven’t been able to reach a consensus on whether animals even have emotions like humans do, let alone how to study them. Yet studies of animal emotion are critical for understanding human emotion and mental illness. In The Nature of the Beast, pioneering neuroscientist David J. Anderson describes a new approach to solving this problem.

Challenging leading scientific theories that claim that our senses report back objective reality, cognitive scientist Donald Hoffman argues that while we should take our perceptions seriously, we should not take them literally. How can it be possible that the world we see is not objective reality? And how can our senses be useful if they are not communicating the truth? Hoffman grapples with these questions and more over the course of this eye-opening work.

This 15-lecture audio course will increase your excitement and wonder about the mysterious organ responsible for so many of the invisible but important things (like love, personality, and emotion) that make us who we are. The field of neuroscience is booming, heralding bold new discoveries and fresh insights into human nature, our behaviors, the mind - body connection, and even artificial intelligence. Now, How Your Brain Works: A User’s Guide to Neuropsychology gives you exactly the sort of orientation you need to contextualize these discoveries and understand your brain.

Do antidepressants work, or are they no better than placebos? Like his colleagues, Irving Kirsch spent years referring patients to psychiatrists to have their depression treated with drugs. Eventually, however, he decided to investigate for himself just how effective the drugs actually were. With 15 years of research, Kirsch demonstrates that what everyone “knew” about antidepressants is wrong; what the medical community considered a cornerstone of psychiatric treatment is little more than a faulty consensus.

Written by one of the world's leading dinosaur experts, Uncovering Dinosaur Behavior is a foundational work on the subject and an invaluable reference for anyone interested in these amazing creatures.

The definitive guide to the medicinal plant knowledge of Ashkenazi herbal healers--from the Middle Ages to the 20th century. Until now, the herbal traditions of the Ashkenazi people have remained unexplored and shrouded in mystery. Ashkenazi Herbalism rediscovers the forgotten legacy of the...

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.

Life histories can be defined as the means by which individuals (or more precisely genotypes) vary their age- or stage-specific expenditures of reproductive effort in response to genetic, phenotypic, and environmental correlates of survival and fecundity. Life histories reflect the expression of traits most closely related to individual fitness, such as age and size at maturity, number and size of offspring, and the timing of the expression of those traits throughout an individual's life. Life-history research plays an integral role in species conservation and management.

Biomimetics literally means emulating biology—and in a broader sense the term covers technological advances where the original inspiration came from nature. The Earth is a vast laboratory where the mechanisms of natural selection have enabled evolutionary solutions to be developed to a wide range of problems. Science writer Brian Clegg looks at how humans have piggybacked on natural experimentation, redeploying a solution to create things that make our lives easier.

This complete study guide from Made Easy Academy transforms every essential concept—from protein structure and enzyme kinetics to metabolic pathways and molecular biology—into straightforward explanations designed for how you actually learn.

Impassioned and eloquent, Black Bear is a story of grief and a vision of peaceful coexistence in a divided world. It captures the fragility of our relationships with human and nonhuman species alike, and the imperative to protect the wild—along with the people we hold closest.

From beneficial yeasts that aid digestion to toxic molds that cause disease, we are constantly navigating a world filled with fungi. Molds, Mushrooms, and Medicines explores the amazing ways fungi interact with our bodies, showing how our health and well-being depend on an immense ecosystem of yeasts and molds inside and all around us.

Homo sapiens emerged as a species about 200,000 years ago and soon—with fire, simple tools, and an egalitarian social system—we inhabited every continent. But now our infinitely elaborated tools and our highly non-egalitarian social system threaten sustainability. Many at the bottom lose the desire to live, committing suicide or succumbing to drugs, alcohol, and obesity. What is Health? explains from the bottom up—molecules to society—how we reached this point.
