Inside our heads we carry around an infinite and endlessly unfolding map of the world. Navigation is one of the most ancient neural abilities we have—older than language. In Dark and Magical Places, Christopher Kemp embarks on a journey to discover the remarkable extent of what our minds can do. Fueled by his own spatial shortcomings, Kemp describes the brain regions that orient us in space and the specialized neurons that do it. Place cells. Grid cells. He examines how the brain plans routes, recognizes landmarks, and makes sure we leave a room through a door instead of trying to leave through a painting. From the secrets of supernavigators like the indigenous hunters of the Bolivian rainforest to the confusing environments inhabited by people with place blindness, Kemp charts the myriad ways in which we find our way and explains the cutting-edge neuroscience behind them. How did Neanderthals navigate? Why do even seasoned hikers stray from the trail? What spatial skills do we inherit from our parents? How can smartphones and our reliance on GPS devices impact our brains? In engaging, engrossing language, Kemp unravels the mysteries of navigating and links the brain's complex functions to the effects that diseases like Alzheimer's, types of amnesia, and traumatic brain injuries have on our perception of the world around us.Ver libro
Immunology is the branch of biomedical science that focuses on the study of the immune system, its functions, and the role it plays in protecting the body from pathogens and other harmful invaders. It encompasses the recognition of foreign molecules and the activation of mechanisms to neutralize or eliminate these threats, while maintaining tolerance to self-tissues. Immunology is an evolving field that links various disciplines, including microbiology, genetics, and molecular biology, in understanding how the body defends itself against diseases. The immune system is a complex network of cells, proteins, and organs that work together to provide protection against infections and malignancies. It is composed of two major arms: innate and adaptive immunity. Innate immunity is the first line of defense, offering a rapid but non-specific response to a wide range of pathogens. In contrast, adaptive immunity is more specialized, offering a delayed but highly specific response to pathogens, with the ability to "remember" previous encounters and respond more effectively in the future. Historically, the field of immunology has been shaped by significant discoveries that have helped define the immune system's components and their roles. The work of pioneers such as Louis Pasteur, Edward Jenner, and Robert Koch laid the foundation for our understanding of immunity, particularly in relation to vaccines and infectious diseases. As research advanced, immunology expanded into areas like autoimmunity, immunodeficiencies, and cancer immunology, offering new insights into disease mechanisms and therapeutic strategies.Ver libro
Symbiosis, the sustained and intimate associations between unrelated life forms, is now recognized as a ubiquitous phenomenon, one that has shaped evolution since the origin of life and that continues to affect all species. This overview of symbiosis starts with a quick history of relevant early discoveries and researchers, and considers why symbiosis was so long neglected as a respectable topic of biological research and why it was a controversial topic. Today, symbiosis is widely appreciated as being everywhere in nature and as a pervasive influence on ecological communities. One chapter explores the fundamental drivers that lead to symbiotic associations, using examples to illustrate the nature of services exchanged between symbiotic partners. Another considers the evolutionary stability of symbiotic partnerships, which can quickly decay in the face of symbiotic cheating. A full chapter is devoted to the most consequential of all symbioses: the origin of the complex (eukaryotic) cell, and the origin of chloroplasts and green plants. Other triumphs of symbiosis described include the root-fungus associations that enabled plants to colonize land 450 million years ago, gut microbial communities that empower animals to utilize a wide range of foods, including plant fiber wood and sap, and coral-algal symbioses that resulted in the rise of coral reefs.Ver libro
