**THE SUNDAY TIMES BESTSELLER | BBC RADIO 4 BOOK OF THE WEEK** Preventable tells the extraordinary story of COVID-19 and how global politics shape our health - from a world-leading expert and the pandemic's go-to science communicator Professor Devi Sridhar has risen to prominence for her vital roles in communicating science to the public and speaking truth to power. In Preventable she highlights lessons learned from outbreaks past and present in a narrative that traces the COVID-19 pandemic - including her personal experience as a scientist - and sets out a vision for how we can better protect ourselves from the inevitable health crises to come. In gripping and heartfelt prose, Sridhar exposes the varied realities of those affected (from the jailed doctor in Wuhan who sounded the alarm, and the bored passengers marooned on the Diamond Princess cruise ship, to the daily nightmares of exhausted healthcare workers), and puts you in the room with key decision makers at crucial moments (from over-confident heads of states and their hesitant scientific advisors, to the beleaguered leaders of global health organisations). Sridhar vibrantly conveys the twists and turns of a plot that saw: deadlier variants emerge (contrary to the predictions of social media pundits who argued it would mutate to a milder form); the Pyrrhic victory in many countries of the false narrative of health versus the economy (those countries which controlled the virus, like Taiwan and Denmark, had a steadier recovery); countries with weak health systems like Senegal and Vietnam fare better than countries like the US and UK (which were consistently ranked as the most prepared); and the quickest development of game-changing vaccines in history (and their unfair distribution). Combining science, politics, ethics and economics, this definitive book dissects the global structures that determine our fate, and reveals the deep-seated economic and social inequalities at their heart - it will challenge, outrage and inspire. 'A brutally compelling reminder that if voices like Devi's had been listened to, so many more could have lived' OWEN JONES 'One of the most brilliant scientists in the world who has been proven consistently right in this crisis' PIERS MORGAN 'Excellent . . . Fair, clear and compelling' NICOLA STURGEON 'Those who have found Professor Devi Sridhar's expertise and calm advice invaluable since the arrival of Covid-19 will be glad to know that she has written Preventable' RACHEL COOKE, Guardian, Non-fiction to look out for in 2022

Population Biology of Vector-Borne Diseases is the first comprehensive survey of this rapidly developing field. The chapter topics provide an up-to-date presentation of classical concepts, reviews of emerging trends, synthesis of existing knowledge, and a prospective agenda for future research. The contributions offer authoritative and international perspectives from leading thinkers in the field. The dynamics of vector-borne diseases are far more intrinsically ecological compared with their directly transmitted equivalents. The environmental dependence of ectotherm vectors means that vector-borne pathogens are acutely sensitive to changing environmental conditions. Although perennially important vector-borne diseases such as malaria and dengue have deeply informed our understanding of vector-borne diseases, recent emerging viruses such as West Nile virus, Chikungunya virus, and Zika virus have generated new scientific questions and practical problems. The study of vector-borne disease has been a particularly rich source of ecological questions, while ecological theory has provided the conceptual tools for thinking about their evolution, transmission, and spatial extent. Population Biology of Vector-Borne Diseases is an advanced textbook suitable for graduate level students taking courses in vector biology, population ecology, evolutionary ecology, disease ecology, medical entomology, viral ecology/evolution, and parasitology, as well as providing a key reference for researchers across these fields.

'Lucid, calm, informed, directly helpful in trying to think about where we are now... The literature of the time after begins here' Evening Standard 'Taking a breather from bewildering statistics and terrible tales of contagion to read Giordano's book was a jolt of brevity and simplicity... It takes concepts that have been dancing away in our minds, just out of reach, and lines them up neatly' The Times 'Potent and original' Sunday Times 'In one short hour, in the midst of this difficult moment, Giordano reinforced my sense of hope in humanity, in the one and the many' Philippe Sands, author of East West Street and The Rat Line The Covid-19 pandemic is the most significant health emergency of our time. Writing from Italy in lockdown, physicist and novelist Paolo Giordano explains how disease spreads in our interconnected world: why it matters how it impacts us how we must react Expanding his focus to include other forms of contagion - from the environmental crisis to fake news and xenophobia - Giordano shows us not just how the coronavirus crisis got so bad so quickly, but also how we can work together to create change. Paolo Giordano is a physicist and the author of four bestselling novels. His article 'The Mathematics of Contagion' - published in Italy at the beginning of the coronavirus emergency - was shared more than 4 million times and helped shift public opinion in the early stages of the epidemic.

Viruses are the most abundant biological entities on Earth, and arguably the most successful. They are not technically alive, but-as infectious vehicles of genetic information-they have a remarkable capacity to invade, replicate, and evolve within living cells. Synthesizing a large body of recent research, Michael Cordingley goes beyond our familiarity with viral infections to show how viruses spur evolutionary change in their hosts, shape global ecosystems, and influence every domain of life. In the last few decades, research has revealed that viruses are fundamental to the photosynthetic capacity of the world's oceans and the composition of the human microbiome. Perhaps most fascinating, viruses are now recognized as remarkable engines of the genetic innovation that fuels natural selection and catalyzes evolution in all domains of life. Viruses have coevolved with their hosts since the beginning of life on our planet and are part of the evolutionary legacy of every species that has ever lived. Cordingley explains how viruses are responsible for the creation of many feared bacterial diseases and the emergence of newly pathogenic and drug-resistant strains. And as more and more viruses jump to humans from other animals, new epidemics of viral disease will threaten global society. But Cordingley shows that we can adapt, relying on our evolved cognitive and cultural capacities to limit the consequences of viral infections. Piecing together the story of viruses' major role within and beyond human disease, Viruses creates a valuable roadmap through the rapidly expanding terrain of virology.

RNA viruses provide unique insights into the patterns and processes of evolutionary change in real time. The study of viral evolution is especially topical given the growing awareness that emerging and re-emerging diseases (most of which are caused by RNA viruses) represent a major threat to public health. However, while the study of viral evolution has developed rapidly in the last 30 years, relatively little attention has been directed toward linking work on the mechanisms of viral evolution within cells or individual hosts, to the epidemiological outcomes of these processes. This novel book fills this gap by considering the patterns and processes of viral evolution across their entire range of spatial and temporal scales. The Evolution and Emergence of RNA Viruses provides a comprehensive overview of RNA virus evolution, with a particular focus on genomic and phylogenetic approaches. This is the first book to link mechanisms of viral evolution with disease dynamics, using high-profile examples in emergence and evolution such as influenza, HIV, dengue fever, and rabies. It also reveals the underlying evolutionary processes by which emerging viruses cross species boundaries and spread in new hosts.

A virologist's insight into how viruses evolve and why global epidemics are inevitable.

In 1993 a previously healthy young man was drowning in the middle of a desert, in fluids produced by his own lungs. This was the beginning of the terrifying Sin Nombre hantavirus epidemic and the start of a scientific journey that would forever change our understanding of what it means to be human. After witnessing the Sin Nombre outbreak, Dr Frank Ryan began researching viral evolution and was astonished to discover that it's inextricable from the evolution of all life on Earth. From AIDS and Ebola to the common cold, Ryan explores the role of the virus within every ecosystem on the planet.

His gripping conclusions shed new light on the natural world, proving that what doesn't kill you really does make you (and your species) stronger.

The reproduction and spread of a virus during an epidemic proceeds when the virus attaches to a host cell and viral genetic material (VGM) (protein, DNA, RNA) enters the cell, then replicates, and perhaps mutates, in the cell. The movement of the VGM across the host cell outer membrane and within the host cell is a spatiotemporal dynamic process that is modeled in this book as a system of ordinary and partial differential equations (ODE/PDEs). The movement of the virus proteins through the cell membrane is modeled as a diffusion process expressed by the diffusion PDE (Fick's second law). Within the cell, the time variation of the VGM is modeled as ODEs. The evolution of the dependent variables is computed by the numerical integration of the ODE/PDEs starting from zero initial conditions (ICs). The departure of the dependent variables from zero is in response to the virus protein concentration at the outer membrane surface (the point at which the virus binds to the host cell). The numerical integration of the ODE/PDEs is performed with routines coded (programmed) in R, a quality, open-source scientific computing system that is readily available from the Internet. Formal mathematics is minimized, e.g., no theorems and proofs. Rather, the presentation is through detailed examples that the reader/researcher/analyst can execute on modest computers. The ODE/PDE dependent variables are displayed graphically with basic R plotting utilities. The R routines are available from a download link so that the example models can be executed without having to first study numerical methods and computer coding. The routines can then be applied to variations and extensions of the ODE/PDE model, such as changes in the parameters and the form of the model equations.

Science doesn't speak for itself. Neck-deep in work that can be messy and confounding and naive in the ways of public communication, scientists are often unable to package their insights into the neat narratives that the public requires. Enter celebrities, advocates, lobbyists, and the funders behind them, who take advantage of scientists' reluctance to provide easy answers, flooding the media with misleading or incorrect claims about health risks. Amid this onslaught of spurious information, Americans are more confused than ever about what's good for them and what isn't. In Bad Advice, Paul A. Offit shares hard-earned wisdom on the dos and don'ts of battling misinformation. For the past twenty years, Offit has been on the front lines in the fight for sound science and public heath. Stepping into the media spotlight as few scientists have done-such as being one of the first to speak out against conspiracy theories linking vaccines to autism-he found himself in the crosshairs of powerful groups intent on promoting pseudoscience. Bad Advice discusses science and its adversaries: not just the manias stoked by slick charlatans and their miracle cures but also corrosive, dangerous ideologies such as Holocaust and climate-change denial. Written with wit and passion, Offit's often humorous guide to taking on quack experts and self-appointed activists is a must-read for any American disturbed by the uptick in politicized attacks on science.

Advances in molecular biology have enabled leaps forward in the determination of virus phylogenetic history. This detailed 1995 book results from the invitation to foremost experts to give essays on aspects of virus biology. Initial chapters cover impacts of viruses and their control. Further chapters detail genetic variation of viruses and the molecular basis of interrelations with hosts. This leads to discussions of interactions with the host at the population level, and their molecular basis and evolution. Seventeen chapters follow, by specialists on particular groups of viruses describing their impact, genetic origins, sources of variation, population genetics and interactions with hosts. Practical virologists will find the chapters on phylogenetic analysis techniques very useful. The adaptive nature of viruses makes this work highly relevant to evolutionists.

Tim Moore completes his epic (and ill-advised) trilogy of cycling's Grand Tours. Julian Berrendero's victory in the 1941 Vuelta a Espana was an extraordinary exercise in sporting redemption: the Spanish cyclist had just spent 18 months in Franco's concentration camps, punishment for expressing Republican sympathies during the civil war. Seventy nine years later, perennially over-ambitious cyclo-adventurer Tim Moore developed a fascination with Berrendero's story, and having borrowed an old road bike with the great man's name plastered all over it, set off to retrace the 4,409km route of his 1941 triumph - in the midst of a global pandemic. What follows is a tale of brutal heat and lonely roads, of glory, humiliation, and then a bit more humiliation. Along the way Tim recounts the civil war's still-vivid tragedies, and finds the gregarious but impressively responsible locals torn between welcoming their nation's only foreign visitor, and bundling him and his filthy bike into a vat of antiviral gel.

When we think about viruses we tend to consider ones that afflict humans--such as those that cause influenza, HIV, and Ebola. Yet, vastly more viruses infect single-celled microbes. Diverse and abundant, microbes and the viruses that infect them are found in oceans, lakes, plants, soil, and animal-associated microbiomes. Taking a vital look at the "microscopic" mode of disease dynamics, Quantitative Viral Ecology establishes a theoretical foundation from which to model and predict the ecological and evolutionary dynamics that result from the interaction between viruses and their microbial hosts. Joshua Weitz addresses three major questions: What are viruses of microbes and what do they do to their hosts? How do interactions of a single virus-host pair affect the number and traits of hosts and virus populations? How do virus-host dynamics emerge in natural environments when interactions take place between many viruses and many hosts? Emphasizing how theory and models can provide answers, Weitz offers a cohesive framework for tackling new challenges in the study of viruses and microbes and how they are connected to ecological processes--from the laboratory to the Earth system. Quantitative Viral Ecology is an innovative exploration of the influence of viruses in our complex natural world.

Exploring the broad implications of evolutionary theorist Lynn Margulis's work, this collection brings together specialists across a range of disciplines, from paleontology, molecular biology, evolutionary theory, and geobiology to developmental systems theory, archaeology, history of science, cultural science studies, and literature and science. Addressing the multiple themes that animated Margulis's science, the essays within take up, variously, astrobiology and the origin of life, ecology and symbiosis from the microbial to the planetary scale, the coupled interactions of earthly environments and evolving life in Gaia theory and earth system science, and the connections of these newer scientific ideas to cultural and creative productions. Dorion Sagan acquaints the reader with salient issues in Lynn Margulis's scientific work, the controversies they raised, and the vocabulary necessary to follow the arguments. Sankar Chatterjee synthesizes several strands of current theory for the origin of life on earth. James Strick tells the intertwined origin stories of James Lovelock's Gaia hypothesis and Margulis's serial endosymbiosis theory. Jan Sapp explores the distinct phylogenetic visions of Margulis and Carl Woese. Susan Squier examines the epigenetics of embryologist and developmental biologist C. H. Waddington. Bruce Clarke studies the convergence of ecosystem ecology, systems theory, and science fiction between the 1960s and the 1980s. James Shapiro discusses the genome evolution that results not from random changes but rather from active cell processes. Susan Oyama shows how the concept of development balances an over-emphasis on genetic coding and other deterministic schemas. Christopher Witmore studies the ways in which a concentrated animal feeding operation, or CAFO, mixes up natural resources, animal lives, and human appetites. And Peter Westbroek brings the insights of earth system science toward a new worldview essential for a proper response to global change.

From biology to economics to information theory, the theme of interdependence is in the air, framing our experiences of all sorts of everyday phenomena. Indeed, the network may be the ascendant metaphor of our time. Yet precisely because the language of interdependence has become so commonplace as to be almost banal, we miss some of its most surprising and far-reaching implications. In Interdependence, biologist Kriti Sharma offers a compelling alternative to the popular view that interdependence simply means independent things interacting. Sharma systematically shows how interdependence entails the mutual constitution of one thing by another—how all things come into being only in a system of dependence on others. In a step-by-step account filled with vivid examples, Sharma shows how a coherent view of interdependence can help make sense not only of a range of everyday experiences but also of the most basic functions of living cells. With particular attention to the fundamental biological problem of how cells pick up signals from their surroundings, Sharma shows that only an account which replaces the perspective of “individual cells interacting with external environments” with one centered in interdependent, recursive systems can adequately account for how life works. This book will be of interest to biologists and philosophers, to theorists of science, of systems, and of cybernetics, and to anyone curious about how life works. Clear, concise, and insightful, Interdependence: Biology and Beyond explicitly offers a coherent and practical philosophy of interdependence and will help shape what interdependence comes to mean in the twenty-first century.

A renaissance of virus research is taking centre stage in biology. Empirical data from the last decade indicate the important roles of viruses, both in the evolution of all life and as symbionts of host organisms. There is increasing evidence that all cellular life is colonized by exogenous and/or endogenous viruses in a non-lytic but persistent lifestyle. Viruses and viral parts form the most numerous genetic matter on this planet.

The decision to write a book about the practical aspects of the baculovirus expression system stems from the numerous phone calls for help we have had, and from the many visitors to our labora tories requiring assistance to find the elusive polyhedrin-negative virus containing their favourite gene. We have also organized two expression system workshops and from the manuals we wrote for these, it seemed a logical progression to extend them into book form. We appreciate that those who are 'old-hands' at the baculovirus expression system may have differing views on some of our procedures, but the methods in this book are presented in the light of our own experiences in the laboratory and from our practical workshops, and we hope that the book will be especially useful to those new to the system. The first three chapters give the background information to the baculovirus expression system, and includes advice on how to choose the right transfer vector and discusses the various methods that are available to select recombinant viruses. The practical chapters concentrate on those aspects which are novel to the baculovirus system (insect cell culture, virus amplification and titration, etc. ) and, in general, leave the standard molecular biological techniques to the other excellent laboratory manuals that are available. However, for completeness sake and to avoid constant reference to other manuals, we have included brief details of some standard techniques where they are integral to the success of the baculovirus protocols."

Praised forits clarity of presentation and accessibility, Introduction to Modern Virology has been a successful student text for over 30 years. It provides a broad introduction to virology, which includes the nature of viruses, the interaction of viruses with their hosts and the consequences of those interactions that lead to the diseases we see. This new edition contains a number of important changes and innovations including: * The consideration of immunology now covers two chapters, one on innate immunity and the other on adaptive immunity, reflecting the explosion in knowledge of viral interactions with these systems. * The coverage of vaccines and antivirals has been expanded and separated into two new chapters to reflect the importance of these approaches to prevention and treatment. * Virus infections in humans are considered in more detail with new chapters on viral hepatitis, influenza, vector-borne diseases, and exotic and emerging viral infections, complementing an updated chapter on HIV. * The final section includes three new chapters on the broader aspects of the influence of viruses on our lives, focussing on the economic impact of virus infections, the ways we can use viruses in clinical and other spheres, and the impact that viruses have on the planet and almost every aspect of our lives. A good basic understanding of viruses is important for generalists and specialists alike. The aim of this book is to make such understanding as accessible as possible, allowing students across the biosciences spectrum to improve their knowledge of these fascinating entities.

A virus is not human, but the reaction to it is a measure of humanity.

America has not measured up well. Tens of thousands are dead for no reason. America is supposed to be about freedom, yet illness and fear make its citizens less free. After all, freedom is meaningless if we are too ill to think about our right to happiness or too weak to pursue it. So, if a government is making its people unhealthy it is also making them unfree.

On December 29, 2019, Timothy Snyder fell gravely ill. As he clung to life he found himself reflecting on the fragility of health, not recognized in America as a human right, but without which all rights and freedoms have no meaning. And that was before the pandemic. We have since watched understaffed and undersupplied hospitals buckling under waves of coronavirus patients. The federal government made matters worse through wilful ignorance, misinformation, and profiteering.

This passionate intervention outlines the lessons we must all learn, wherever we are, and finds glimmers of hope in dark times. Only by enshrining healthcare as a human right, elevating the authority of doctors and truth, and planning for our children's future, can everyone be properly free.

Freedom belongs to individuals. But to be free we need our health, and for our health we need one another.

Like other biomedical sciences, medical virology has undergone a revolution of diagnostic and scientific approaches through the advent of molecular biological techniques. Developing and maintaining an appropriate mixture of classical and molecular techniques for viral analysis is one of the challenges of medical virology today, and this volume addresses these issues. Topics covered include a broad description of "classical" techniques in viral diagnosis, nucleic acid detection by extraction and hybridization, use of the polymerase chain reaction, the application of various molecular techniques to aspects of the epidemiology of virus infections, and the principles and practical approaches to the analysis of viral evolution. The book will be of interest to students, researchers and professionals in medical virologoy, particularly hospital workers, microbiology, and molecular biology.
