Now You See Them, Now You Don't: Poems About Creatures that Hide

by David L. Harrison

Find me if you can. . . for if you don&’t, I&’ll be here tomorrow . . . you won&’t. Animals and insects use camouflage to hide from hunters or to ambush prey. Stealth is a very useful technique when it comes to survival. In this fun and informative collection of poems, we meet animals such as the polar bear and the octopus; the ghost crab and the copperhead snake; and many more that use camouflage to hunt or to hide. Giles Laroche&’s intricate cut-paper illustrations are beautiful and life-like. Readers will have to look carefully or run the risk of a hunter sneaking up on them. Back matter offers additional information about each of the nineteen animals.

Nowhere Left to Go: How Climate Change Is Driving Species To The Ends Of The Earth

by Benjamin von Brackel

Harrowing journeys of animals and plants—fleeing skyrocketing temperatures and mega-droughts—reported from the frontlines of the greatest migration of species since the Ice Age As humans accelerate global warming while laying waste to the environment, animals and plants must flee to the margins: on scattered nature reserves, between major highways, or among urban sprawl. And when even these places become too hot and inhospitable, wildlife is left with only one path to survival: an often-formidable journey toward the poles as they race to find a new home in a warming world. Tropical zones lose their inhabitants, beavers settle in Alaska, and gigantic shoals of fish disappear—just to reappear along foreign coastlines. Award-winning environmental journalist Benjamin von Brackel traces these awe-inspiring journeys and celebrates the remarkable resilience of species around the world. But the lengths these plants and animals must go to avoid extinction are as alarming as they are inspirational: Sea animals—like fish—move on average 45 miles a decade to cooler regions, while land animals—like beavers and butterflies—move 11 miles. As even the poles of the Earth heat up, we’re left with a stark and irreversible choice: Halt the climate emergency now, or face a massive die-off of species, who are increasingly left with nowhere else to go.

Nrf2 and its Modulation in Inflammation (Progress in Inflammation Research #85)

by Huai Deng

Nrf2, a transcription factor that mediates transcriptional responses to oxidative and xenobiotic stresses, plays a central role in cellular protection against internal or external toxins. Defects in Nrf2 and the relevant regulatory pathways are associated with a number of pathologies including inflammation, respiratory diseases, cardiovascular dysfunctions, metabolic syndrome and diabetes, neurodegeneration, and cancer. This book comprehensively reviews the up-to-date discoveries for the roles of Nrf2 in several human diseases in the context of inflammation. In particular, the molecular mechanisms that mediate the functions of Nrf2 and its interacting network in inflammation and pathogenesis are explicated. In addition, the research and therapeutic applications of Nrf2-targeting compounds in different diseases were summarized. This book is expected to be a valuable reference for worldwide researchers conducting both mechanistic and therapeutic studies of Nrf2 and relevant factors.

NSCI 120: Modern Biology Lab Manual

by Dickey

Scientific inquiry is a particular way of answering questions. It can’t be used for all types of questions. The questions that can be answered by science must meet specific guidelines and scientific investigations must be carried out using certain rules. When an investigation is designed properly and meets these guidelines, then the results are acceptable to other scientists and are added to the body of scientific knowledge. If an investigator cannot show that his or her experiment was done according to the guidelines, then the results of that experiment will not be recognized as valid by other scientists.

Nuclear and Radiological Emergencies in Animal Production Systems, Preparedness, Response and Recovery

by Gerrit Viljoen Ivancho Naletoski Anthony G. Luckins

This Open Access volume explains how major nuclear and radiological emergencies (NREs) can have implications at local, national and international level. The response to NREs requires a competent decision-making structure, clear communication and effective information exchange. National veterinary services have the responsibility to plan, design and manage animal production system in their countries. These activities cover animal health, animal movement control, production control and improvement, and control of the products of animal origin before their placement on the market. Release of radionuclides after NREs can cause substantial contamination in the animal production systems. Critical responsibility of veterinary authorities is therefore to prevent such contamination, establish early response mechanisms to mitigate the consequences and prevent placement of contaminated products of animal origin on the market for human consumption. This work summarizes the critical technical points for effective management of NREs for national veterinary services.

Nuclear Bodies: The Global Hibakusha

by Robert A. Jacobs

The Cold War reconsidered as a limited nuclear war &“Inexorable clarity and care for his fellow humans mark Robert Jacobs's guide to the Cold War as a limited nuclear war, whose harms disfigure any possible future.&”—Norma Field, author of In the Realm of a Dying Emperor: Japan at Century&’s End In the fall of 1961, President Kennedy somberly warned Americans about deadly radioactive fallout clouds extending hundreds of miles from H‑bomb detonations, yet he approved ninety‑six US nuclear weapon tests for 1962. Cold War nuclear testing, production, and disasters like Chernobyl and Fukushima have exposed millions to dangerous radioactive particles; these millions are the global hibakusha. Many communities continue to be plagued with dire legacies and ongoing risks: sickness and early mortality, forced displacement, uncertainty and anxiety, dislocation from ancestors and traditional lifestyles, and contamination of food sources and ecosystems. Robert A. Jacobs re‑envisions the history of the Cold War as a slow nuclear war, fought on remote battlegrounds against populations powerless to prevent the contamination of their lands and bodies. His comprehensive account necessitates a profound rethinking of the meaning, costs, and legacies of our embrace of nuclear weapons and technologies.

Nuclear, Chromosomal, and Genomic Architecture in Biology and Medicine (Results and Problems in Cell Differentiation #70)

by Malgorzata Kloc Jacek Z. Kubiak

This volume reviews the latest research on the functional implications of nuclear, chromosomal and genomic organization and architecture on cell and organismal biology, and development and progression of diseases.The architecture of the cell nucleus and non-random arrangement of chromosomes, genes, and the non-membranous nuclear bodies in the three-dimensional (3D) space alters in response to the environmental, mechanical, chemical, and temporal cues. The changes in the nuclear, chromosomal, or genomic compaction and configuration modify the gene expression program and induce or inhibit epigenetic modifications. The intrinsically programmed rearrangements of the nuclear architecture are necessary for cell differentiation, the establishment of cell fate during development and maturation of tissues and organs including the immune, muscle, and nervous systems.The non-programmed changes in the nuclear architecture can lead to fragmentation of the nucleus and instability of the genome and thus cause cancer. Microbial and viral infections can lead to a clustering of centromeres, telomeres and ribosomal DNA and alter the properties of the nuclear membrane, allowing large immobile macromolecules to enter the nucleus. Recent advances in next-generation sequencing technologies combined with nucleus/chromosome conformation capture, super-resolution imaging, chromosomal contact maps methods, integrative modeling, and genetic approaches, are uncovering novel features and importance of nuclear, chromosomal and genomic architecture. This book is an interesting read for cell biologists, researchers studying the structure and function of chromosomes, and anyone else who wants to get an overview of the field of nuclear, chromosomal and genomic architecture.

Nuclear-Cytoplasmic Transport (Nucleic Acids And Molecular Biology Ser. #33)

by Weidong Yang

Dysfunction of nuclear-cytoplasmic transport systems has been associated with many human diseases. Thus, understanding of how functional this transport system maintains, or through dysfunction fails to maintain remains the core question in cell biology. In eukaryotic cells, the nuclear envelope (NE) separates the genetic transcription in the nucleus from the translational machinery in the cytoplasm. Thousands of nuclear pore complexes (NPCs) embedded on the NE selectively mediate the bidirectional trafficking of macromolecules such as RNAs and proteins between these two cellular compartments. In this book, the authors integrate recent progress on the structure of NPC and the mechanism of nuclear-cytoplasmic transport system in vitro and in vivo.

Nuclear Decommissioning: Planning, Execution And International Experience (Woodhead Publishing Series In Energy Ser.)

by Michele Laraia

This book discusses the history of nuclear decommissioning as a science and industry. It explores the early, little-known period when the term “decommissioning” was not used in the nuclear context and the end-of-life operations of a nuclear facility were a low priority. It then describes the subsequent period when decommissioning was recognized as a separate phase of the nuclear lifecycle, before bringing readers up to date with today’s state of the art.The author addresses decommissioning as a mature industry in an era in which large, commercial nuclear reactors and other fuel-cycle installations have been fully dismantled, and their sites returned to other uses. The book also looks at the birth, growth and maturity of decommissioning, focusing on how new issues emerged, how these were gradually addressed, and the lessons learned from them. Further, it examines the technologies and management advances in science and industry that followed these solutions. Nuclear Decommissioning is a point of reference for industry researchers and decommissioning practitioners looking to enrich their knowledge of decommissioning in recent decades as well as the modern industry. The book is also of interest to historians and students who wish to learn more about the history of nuclear decommissioning.
