Book Description
Since the late 1800s, the discovery of new viruses was a gradual process. Viruses were described one by one using a suite of techniques such as (electron) microscopy and viral culture. Investigators were usually interested in a disease state within an organism, and expeditions in viral ecology were rare. The advent of metagenomics using high-throughput sequencing has revolutionized not only the rate of virus discovery, but also the nature of the discoveries. For example, the viral ecology and etiology of many human diseases are being characterized, non-pathogenic viral commensals are ubiquitous, and the description of environmental viromes is making progress. This Frontiers in Virology Research Topic showcases how metagenomic and bioinformatic approaches have been combined to discover, classify and characterize novel viruses.

Book Description
It is vital to understand ticks and tick-borne pathogens as well as their impact on humans. This book is intended for students in parasitology, biologists, parasitologists involved in molecular diagnostics of tick-borne diseases, practicing veterinarians, and for others who may require information on ticks and tick-borne diseases. Here we have put together a collection of chapters focused on different aspects of ticks and tick-borne diseases mainly to provide the reader with novel information in the field, but not the basic generalised information provided by many textbooks. This book includes topics such as high-throughput technologies in diagnosis, discovery of novel tick vaccines, identification of new pathogens transmitted by ticks, and new epidemiological information of certain well-known ticks and tick-borne diseases. These chapters were authored by parasitologists from all over the world, giving an insight to the reader about significant ticks and tick-borne diseases prevalent in those particular geographical regions with the local expert's point of view. Each of the chapters has separate reference lists, making it easier for the reader to find additional reading material related to their topic of interest.

Book Description
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.

Book Description
Contracts relating to scientific/technical development are effective only where they are enforceable or valid under relevant law, can be practically implemented by the parties, and address matters arising from the relevant scientific/technical issues and practices. Negotiators are often hampered by their lack of knowledge of contract law and of the biotechnological techniques used to derive new molecules and genes or genetic or biochemical formulas from biological samples. This lack of knowledge means they may not make the best choices. This book examines the special issues in applying contract law to the rights to take and utilize genetic resources; and the scientific issues and the manner in which they affect the negotiation of ABS agreements.

Book Description
Concisely discussing the application of high throughput analysis to move forward our understanding of microbial principles, Metagenomics for Microbiology provides a solid base for the design and analysis of omics studies for the characterization of microbial consortia. The intended audience includes clinical and environmental microbiologists, molecular biologists, infectious disease experts, statisticians, biostatisticians, and public health scientists. This book focuses on the technological underpinnings of metagenomic approaches and their conceptual and practical applications. With the next-generation genomic sequencing revolution increasingly permitting researchers to decipher the coding information of the microbes living with us, we now have a unique capacity to compare multiple sites within individuals and at higher resolution and greater throughput than hitherto possible. The recent articulation of this paradigm points to unique possibilities for investigation of our dynamic relationship with these cellular communities, and excitingly the probing of their therapeutic potential in disease prevention or treatment of the future. - Expertly describes the latest metagenomic methodologies and best-practices, from sample collection to data analysis for taxonomic, whole shotgun metagenomic, and metatranscriptomic studies - Includes clear-headed pointers and quick starts to direct research efforts and increase study efficacy, eschewing ponderous prose - Presented topics include sample collection and preparation, data generation and quality control, third generation sequencing, advances in computational analyses of shotgun metagenomic sequence data, taxonomic profiling of shotgun data, hypothesis testing, and mathematical and computational analysis of longitudinal data and time series. Past-examples and prospects are provided to contextualize the applications.

Book Description
The paper begins with a retrospective of the debates on the origin of life: the virus or the cell? The virus needs a cell for replication, instead the cell is a more evolved form on the evolutionary scale of life. In addition, the study of viruses raises pressing conceptual and philosophical questions about their nature, their classification, and their place in the biological world. The subject of pandemics is approached starting from the existentialism of Albert Camus and Sartre, the replacement of the exclusion ritual with the disciplinary mechanism of Michel Foucault, and about the Gaia hypothesis, developed by James Lovelock and supported in the current pandemic by Bruno Latour. The social dimensions of pandemics, their connection to global warming, which has led to an increase in infectious diseases, and the deforestation of large areas, which have caused viruses to migrate from their native area (their "reservoir") are highlighted below. The ethics of pandemics is approached from several philosophical points of view, of which the most important in a crisis of such global dimensions is utilitarianism which involves maximizing benefits for society in direct conflict with the usual (Kantian) view of respect for people as individuals. After a retrospective of the COVID-19 virus that caused the current pandemic, its life cycle and its history, with an emphasis on the philosophy of death, the concept of biopower initially developed by Foucault is discussed, with reference to the practice of modern states of control of the populations and the debate generated by Giorgio Agamben who states that what is manifested in this pandemic is the growing tendency to use the state of emergency as a normal paradigm of government. An interesting and much debated approach is the one generated by the works of Slavoj Žižek, who states that the current pandemic has led to the bankruptcy of the current "barbaric" capitalism, wondering if the path that humanity will take is a neo-communism. Another important negative effect is desocialization, with the conclusion of some philosophers that we cannot exist independently of our relationships with others, that a person's humanity depends on the humanity of those around him. The last section is dedicated to forecasting what the world will look like after the pandemic, and there are already signs of a paradigm shift, including the sudden disappearance of the "wall" ideology: a cough was enough to make it suddenly impossible to avoid the responsibility that every individual has it towards all living beings for the simple fact that he is part of this world, and of the desire to be part of it. The whole is always involved in part, because everything is, in a sense, in everything and in nature there are no autonomous regions that are an exception. The COVID-19 pandemic seems to restore the supremacy that once belonged to politics. One of the virtues of the virus is its ability to generate a more sober idea of ​​freedom: to be free means to do what needs to be done in a specific situation.

Book Description
The book compiles the latest studies on microorganisms thriving in extreme conditions. Microbes have been found in extremely high and low temperatures, highly acidic to saline conditions, from deserts to the Dead sea, from hot-springs to underwater hydrothermal vents- the diversity is incredible. The various chapters highlight the microbial life and describe the mechanisms of tolerance to these harsh conditions, and show how an understanding of these phenomena can help us exploit the microbes in biotechnology. The theme of the book is highly significant since life in these environments can give vital clues about the origin and evolution of life on earth, as a lot of these conditions simulate the environment present billions of years ago. Additionally, the study of adaptation and survival of organisms in such environments can be important for finding life on other planets. This book shall be useful for students, researchers and course instructors interested in evolution, microbial adaptations and ecology in varied environments.
