The marvelous microbes that made life on Earth possible and support our very existenceFor almost four billion years, microbes had the primordial oceans all to themselves. The stewards of Earth, these organisms transformed the chemistry of our planet to make it habitable for plants, animals, and us. Life's Engines takes readers deep into the microscopic world to explore how these marvelous creatures made life on Earth possible-and how human life today would cease to exist without them.Paul Falkowski looks "e;under the hood"e; of microbes to find the engines of life, the actual working parts that do the biochemical heavy lifting for every living organism on Earth. With insight and humor, he explains how these miniature engines are built-and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies. Falkowski shows how evolution works to maintain this core machinery of life, and how we and other animals are veritable conglomerations of microbes.A vibrantly entertaining book about the microbes that support our very existence, Life's Engines will inspire wonder about these elegantly complex nanomachines that have driven life since its origin. It also issues a timely warning about the dangers of tinkering with that machinery to make it more "e;efficient"e; at meeting the ever-growing demands of humans in the coming century.

This book provides an overview of the recent advancements for plant scientists with a research focus on phytohormones and their responses (nature, occurrence, and functions) in plant cells.This book focuses on the role of phytohormones in biosynthesis, plant sexual reproduction, seed germination and fruit development and ripening. It further highlights the roles of different phytohormones on signaling pathways as well as on photoperiodism/Gravitropism/Thigmotropism.The volume also explores the role of phytohormones in gene expression and plant melatonin and serotonin and covers how plant hormones react in case of stress/defence response (metals/metalloids/pathogen). Last but not least, this volume also discusses phytohormones in the context of new regulatory molecules such as Nitric oxide, hydrogen sulfide, melatonin.

This second edition volume expands on the previous edition with new information on the structural analysis of glycosaminoglycans (GAGs); chemical and enzymatic synthesis of GAGs; biophysical, biochemical, and computational analysis of GAG-protein interactions; molecular and genetic approaches to manipulating GAG cell biology; and molecular and genetic methods involving animal models and organoids. This volume also offers insight and guidance to non-glycoscience researchers who are performing advanced experiments on GAGs. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. \Cutting-edge and authoritative, Glycosaminoglycans: Methods and Protocols, Second Edition is a valuable experimental manual for practicing researchersincluding graduate and post-doctoral fellows, and provides them with the latest methodologies and practical tips to overcoming barriers in understanding the chemistry and biology of GAGs.

Environmental issues such as ozone layer depletion, overpopulation, biodiversity loss, global warming, natural resource depletion, and so on affect every organism on the planet somehow. Environmental biotechnology applications can help to protect and restore the quality of the environment. The goal is to use biotechnology with other technologies and safety procedures to prevent, arrest, and reverse environmental degradation. Environmental biotechnology is one of the most rapidly expanding and practically useful scientific fields. Biochemistry, physiology and genetic research of microorganisms can be converted into commercially available technologies for reversing and preventing further deterioration of the earth's environment. Solid, liquid, and gaseous wastes can be altered either by recycling new by-products or by purifying to make the end product less harmful to the environment. Biotechnology for Toxic Remediation and Environmental Sustainability discusses the removal of pollutants by absorption techniques and recycling wastewater into valuable by-products and biofuels by microorganisms. Moreover, this book also addresses corrosion prevention by green inhibitors, uses electrochemical systems for renewable energy and waste recycling using microbes, and recent food safety and security trends in the food microbiome. On the other hand, this book also discusses therapy and treatments against antibiotic-resistant bacteria, anti-cancer and pharmacological properties of thymoquinone and preventive properties of zinc nanoparticles against stress-mediated apoptosis in epithelial cells.FeaturesCovers all aspects of Biotechnological application in the environmentDiscusses sustainable technology for the wastewater treatment and value-added products from wastewaterFocuses on research activities Green corrosion inhibitors, bio-electrochemical systems, food safety and security, and antimicrobial resistanceThe book is a valuable resource for the undergrad and graduate students, doctoral and post-doctoral scholars, industrial personnel, academicians, scientists, researchers, and policymakers involved in understanding and implementing applications of biotechnology for environmental toxic remediation.

This book offers a comprehensive exploration of malaria, a life-threatening disease affecting millions globally, with a focus on the parasitic organisms of the genus Plasmodium that cause it. It discusses the challenges posed by the disease, especially in economically developing regions, and delves into the biology and pathophysiology of the Plasmodium species, including their genetic flexibility and resistance to treatments. Special attention is given to P. falciparum, the most dangerous of these parasites, detailing its complex life cycle, interaction with human hosts, and the severe clinical manifestations it can induce. The book further explores the global health concern of antimalarial drug resistance, highlighting the WHO's efforts in combating the disease and the necessity for novel treatments. Innovative research directions, such as targeting the unique organelles of Plasmodium like the apicoplast and employing proteasome inhibitors, are thoroughly examined as potential strategies in the development of new antimalarial drugs. Additionally, it addresses the critical role of the hemoglobin digestion process in the parasite's lifecycle, presenting it as a promising target for therapeutic intervention. This work is an essential resource for researchers, clinicians, and policymakers involved in malaria control and drug development, providing insights into the current challenges and future directions in the fight against this endemic disease.

"A Mathematical Approach to Special Relativity introduces the mathematical formalisms of special and general relativity. Developed from the author's experience teaching physics to students across all levels, the valuable resource introduces key concepts, building in complexity and using increasingly advanced mathematical tools as it progresses. Without assuming a background in calculus, the text begins with symmetry, before delving more deeply into Galilean relativity. Throughout, the book provides examples and useful 'Guides to the Literature.' This unique text emphasizes the experimental consequences and verifications of the underpinning theory in order to provide students with a solid foundation in this key area."

The latest edition of this text provides an introduction to current risk assessment practices and procedures and explores the intrinsic complexities, challenges, and controversies associated with analysis of environmental health risks.
