How did human beings acquire imaginations that can conjure up untrue possibilities? How did the Universe become self-aware? In The Runes of Evolution, Simon Conway Morris revitalizes the study of evolution from the perspective of convergence, providing us with compelling new evidence to support the mounting scientific view that the history of life is far more predictable than once thought.  A leading evolutionary biologist at the University of Cambridge, Conway Morris came into international prominence for his work on the Cambrian explosion (especially fossils of the Burgess Shale) and evolutionary convergence, which is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches.  In The Runes of Evolution, he illustrates how the ubiquity of convergence hints at an underlying framework whereby many outcomes, not least brains and intelligence, are virtually guaranteed on any Earth-like planet. Conway Morris also emphasizes how much of the complexity of advanced biological systems is inherent in microbial forms.  By casting a wider net, The Runes of Evolution explores many neglected evolutionary questions. Some are remarkably general. Why, for example, are convergences such as parasitism, carnivory, and nitrogen fixation in plants concentrated in particular taxonomic hot spots? Why do certain groups have a particular propensity to evolve toward particular states?  Some questions lead to unexpected evolutionary insights: If bees sleep (as they do), do they dream? Why is that insect copulating with an orchid? Why have sponges evolved a system of fiber optics? What do mantis shrimps and submarines have in common? If dinosaurs had not gone extinct what would have happened next? Will a saber-toothed cat ever re-evolve?  Cona Morris observes: “Even amongst the mammals, let alone the entire tree of life, humans represent one minute twig of a vast (and largely fossilized) arborescence. Every living species is a linear descendant of an immense string of now-vanished ancestors, but evolution itself is the very reverse of linear. Rather it is endlessly exploratory, probing the vast spaces of biological hyperspace. Indeed this book is a celebration of how our world is (and was) populated by a riot of forms, a coruscating tapestry of life.”  The Runes of Evolution is the most definitive synthesis of evolutionary convergence to be published to date.

In the fifteenth century, as astronomers charted the skies and explorers mapped the globe, the nature of life itself remained a mystery. It wasn’t until the seventeenth century that Robert Hooke, looking through one of the earliest microscopes, coined the term cell. Nearly two centuries later, biologists established that all living organisms—from animals and plants to algae and fungi—are composed of cells. Around the same time, Charles Darwin introduced his theory of evolution, proposing that all life on Earth shares a common origin. Today, the scientific community has defined that origin as LUCA—the Last Universal Common Ancestor.Unraveling how LUCA—the ancestral cell—emerged billions of years ago and gradually evolved into the vast diversity of life-forms we see today is a fascinating journey through history, biology, and the essence of what it means to be alive. Blending art with science, biologist Christian Sardet takes you on an exploration of DNA, RNA, proteins, protists, viruses, cell reproduction, aging, death, and more.Written in clear, accessible language and accompanied by artful illustrations, Cells: The Illustrated Story of Life offers an authoritative and visually captivating overview of the building blocks of life. Designed for visual learners and curious minds alike, this immersive exploration of life and evolution brings readers up to date with the latest discoveries—revealing how cells function, how they have evolved, and why they fascinate us.

'One of my favourite science writers' Bill Gates'Hugely important' Jim Al-Khalili'A profound meditation on metabolism, the Krebs cycle & the origin of life' Anil SethFor decades, biology has been dominated by information - the power of genes. Yet there is no difference in information content between a living cell and one that died a moment ago. A better question goes back to the formative years of biology: what processes animate cells and set them apart from lifeless matter?In Transformer, Nick Lane turns the standard view upside down, capturing an extraordinary scientific renaissance that is hiding in plain sight. At its core is an amazing cycle of reactions that uses energy to transform inorganic molecules into the building blocks of life - and the reverse. To understand this cycle is to fathom the deep coherence of the living world. It connects the origin of life with the devastation of cancer, the first photosynthetic bacteria with our own mitochondria, sulphurous sludges with the emergence of consciousness, and the trivial differences between ourselves with the large-scale history of our planet.

For more than four decades, Molecular Biology of the Cell has distilled the vast amount of scientific knowledge to illuminate basic principles, enduring concepts, and cutting-edge research. The Seventh Edition has been extensively revised and updated with the latest research, and has been thoroughly vetted by experts and instructors. The classic companion text, The Problems Book, has been reimagined as the Digital Problems Book in Smartwork, an interactive digital assessment course with a wide selection of questions and automatic-grading functionality. The digital format with embedded animations and dynamic question types makes the Digital Problems Book in Smartwork easier to assign than ever before—for both in-person and online classes.

Imagine that we had some way to look directly at the molecules in a living organism. An x-ray microscope would do the trick, or since we’re dreaming, perhaps an Asimov-style nanosubmarine (unfortunately, neither is currently feasible). Think of the wonders we could witness firsthand: antibodies atta- ing a virus, electrical signals racing down nerve fibers, proteins building new strands of DNA. Many of the questions puzzling the current cadre of sci- tists would be answered at a glance. But the nanoscale world of molecules is separated from our everyday world of experience by a daunting million-fold difference in size, so the world of molecules is completely invisible. I created the illustrations in this book to help bridge this gulf and allow us to see the molecular structure of cells, if not directly, then in an artistic rendition. I have included two types of illustrations with this goal in mind: watercolor paintings which magnify a small portion of a living cell by one million times, showing the arrangement of molecules inside, and comput- generated pictures, which show the atomic details of individual molecules. In this second edition of The Machinery of Life, these illustrations are presented in full color, and they incorporate many of the exciting scientific advances of the 15 years since the first edition.

Incorporating the most important advances in the rapidly-evolving field of cancer biology, this book remains the defining course text on its subject. Students, instructors, researchers, and clinicians the world over admire its authoritative content, clear explanations, extensive full-color art program, and pedagogical features that promote a deep conceptual understanding of the science through the lens of fascinating tales of scientific discovery.

Very Short Introductions: Brilliant, Sharp, Inspiring From the simplest bacteria to humans, all living things are composed of cells of one type or another, all of which have fundamentally the same chemistry. This chemistry must provide mechanisms that allow cells to interact with the external world, a means to power the cell, machinery to carry out varied processes within the cell, a structure within which everything runs, and also governance through a web of interlocking chemical reactions. Biochemistry is the study of those reactions, the molecules that are created, manipulated, and destroyed as a result of them, and the massive macromolecules (such as DNA, cytoskeletons, proteins and carbohydrates) that form the chemical machinery and structures on which these biochemical reactions take place. It didn't take long for an understanding of the chemistry of life to turn into a desire to manipulate it. Drugs and therapies all aim to modify biochemical processes for good or ill: Penicillin, derived from mould, stops bacteria making their cell walls. Aspirin, with its origins in willow bark, inhibits enzymes involved in inflammatory responses. A few nanograms of botulinum toxin (botox), can kill by preventing the release of neurotransmitters from the ends of nerves and so leads to paralysis and death, or give a wrinkle free forehead (if administered in very tiny quantities).This Very Short Introduction discusses the key concepts of biochemistry, as well as the historical figures in the field and the molecules they studied, before considering the current science and innovations in the field, and the interaction between biochemistry, biotechnology, and synthetic biology. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

All living things on Earth are composed of cells. A cell is the simplest unit of a self-contained living organism, and the vast majority of life on Earth consists of single-celled microbes, mostly bacteria. These consist of a simple 'prokaryotic' cell, with no nucleus. The bodies of more complex plants and animals consist of billions of 'eukaryotic' cells, of varying kinds, adapted to fill different roles - red blood cells, muscle cells, branched neurons. Each cell is an astonishingly complex chemical factory, the activities of which we have only begun to unravel in the past fifty years or so through modern techniques of microscopy, biochemistry, and molecular biology.In this Very Short Introduction, Terence Allen and Graham Cowling describe the nature of cells - their basic structure, their varying forms, their division, their differentiation from initially highly flexible stem cells, their signalling, and programmed death. Cells are the basic constituent of life, and understanding cells and how they work is central to all biology and medicine.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

'Timely, important and compelling' Philip Ball'A new and stunning argument' Azra RazaWhat defines who we are?Until now, the biological answer has been our genes. Leading biologist Alfonso Martinez Arias breaks with popular tradition to make a bold argument: what defines us is our cells.Drawing on groundbreaking research, he reveals that we are composed of a thrillingly complex, constantly rearranging symphony of cells that know how to count, feel, and give form to our bodies. While DNA is important, nothing in your genes explains why your heart is on the left, why you have five fingers and not ten, why genetically identical twins have different sets of fingerprints, or why it's possible for a mother to apparently share no DNA with the children she gave birth to! At the heart of it all is a powerful new conception of the essence of life. Our identities are shaped by the interconnections between cells, working cooperatively, creating something greater than its parts - the unbroken lineage that connects us to the fertilized egg from which we developed and back through the billions of years of our planet's history, to the very first cell of all life on Earth.A sweeping revision of both the present and the history of life, The Master Builder puts forward a new paradigm for understanding biology, transforming our approach to where we come from, what shapes us, and where we are going - as individuals, a species, and the community of life itself.

>>Ein auch heute noch bedeutsamer Klassiker<< Daily Express Sind wir Marionetten unserer Gene? Nach Richard Dawkins´ vor über 30 Jahren entworfener und heute noch immer provozierender These steuern und dirigieren unsere von Generation zu Generation weitergegebenen Gene uns, um sich selbst zu erhalten. Alle biologischen Organismen dienen somit vor allem dem Überleben und der Unsterblichkeit der Erbanlagen und sind letztlich nur die "Einweg-Behälter" der "egoistischen" Gene. Sind wir Menschen also unserem Gen-Schicksal hilflos ausgeliefert? Dawkins bestreitet dies und macht uns Hoffnung: Seiner Meinung nach sind wir nämlich die einzige Spezies mit der Chance, gegen ihr genetisches Schicksal anzukämpfen.

The Textbook of Ion Channels is a set of three volumes that provides a wide-ranging refer- ence source on ion channels for students, instructors and researchers. Ion channels are membrane proteins that control the electrical properties of neurons and cardiac cells; mediate the detection and response to sensory stimuli like light, sound, odor, and taste; and regulate the response to physical stimuli like temperature and pressure. In non-excit- able tissues, ion channels are instrumental for the regulation of basic salt balance that is critical for homeostasis. Ion channels are located at the surface membrane of cells, giving them the unique ability to communicate with the environment, as well as the membrane of intracellular organelles, allowing them to regulate internal homeostasis. Ion channels are fundamentally important for human health and diseases, and are important targets for pharmaceuticals in mental illness, heart disease, anesthesia, pain and other clinical appli- cations. The modern methods used in their study are powerful and diverse, ranging from single ion-channel measurement techniques to models of ion channel diseases in animals, and human clinical trials for ion channel drugs.Volume II starts with ion channel taxonomy and features coverage of major ion channel families, and describes the physiological role, structural components, gating mechanisms and biophysics, permeation and selectivity, regulation, pharmacology, and roles in dis- ease mechanisms. Channels in this volume include voltage-activated sodium, calcium and potassium channels, inward-rectifier and two-pore domain potassium channels, calcium- activated potassium channels, cyclic nucleotide-gated channels, pacemaker ion channels, chloride channels, ligand-gated receptors activated by acetylcholine, glutamate, 5-HT3, GABA and glycine, acid-sensing channels, P2X receptors, TRP channels, store-operated channels, pressure-activated piezo channels, ryanodine receptors, and proton channels.All three volumes give the reader an introduction to fundamental concepts needed to understand the mechanism of ion channels; a guide to the technical aspects of ion channel research; offer a modern guide to the properties of major ion channel families; and include coverage of key examples of regulatory, physiological and disease roles for ion channels.
