This book summarizes what is currently known about gravity sensing and response mechanisms in microorganisms, fungi, lower and higher plants; starting from the historical eye-opening experiments from the 19th century up to today’s extremely rapid advancing cellular, molecular and biotechnological research. All forms of life are constantly exposed to gravity and it can be assumed that almost all organisms have developed sensors and respond in one way or the other to the unidirectional acceleration force,this books shows us some of these different ways. The book is written for plant biologists and microbiologists as well as scientists interested in space and gravitational biology.
Unicellular organisms use gravity as an environmental guide to reach and stay in regions optimal for their growth and reproduction. These single cells play a significant role in food webs and these factors together make the effects of gravity on unicellular organisms a fascinating and important subject for scientific study. In addition, they present valuable model systems for studying the mechanisms of gravity perception, a topic of increasing interest in these days of experimentation in space. This book reveals how single cells achieve the same sensoric capacity as multicellular organisms like plants or animals. It reviews the field, discussing the historical background, ecological significance and related physiology of unicellular organisms, as well as various experimental techniques and models with which to study them. Those working on the biology of unicellular organisms, as well as in related areas of gravitational and space science will find this book of value.
This concise yet comprehensive treatment of the effects of spaceflight on biological systems includes issues at the forefront of life sciences research, such as gravitational biology, immune system response, bone cell formation and the effects of radiation on biosystems. Edited by a leading specialist at the European Space Agency (ESA) with contributions by internationally renowned experts, the chapters are based on the latest space laboratory experiments, including those on SPACELAB, ISS, parabolic flights and unmanned research satellites. An indispensable source for biologists, medical researchers and astronautics experts alike. The results of Space flight experiments, ground controls and flight simulations pave the way for a better understanding of gravity reactions in various organisms down to molecular mechanisms. This publication marks also the beginning of a new Space flight era with the construction and exploitation of the International Space Station (ISS) which provides a platform for an in-depth continuation of experiments under weightlessness in Low Earth Orbit and beyond.
This volume of the series Space Life Sciences provides insights into the latest findings of gravity research and the effect of gravity on biological systems, specifically on a cellular and molecular level. It starts by explaining the underlying physics of gravity and presenting some novel ideas on the basic principles of gravity perception. It then goes on to discuss how, in response to gravity perception, secondary messengers such as calcium and hydrogen peroxide, might control responses further downstream, like gene and protein expression and modulation. Further, it describes the consequences for animal and plant cells as well as for metabolism. Written by experts in the field, this book is a valuable resource for students and researchers in biochemistry, medicine and biomedicine, wanting to gain a solid understanding of membrane biology, secondary messenger function and gene and protein expression, specifically in the context of gravity.
This book examines the effects of spaceflight at cellular and organism levels. Research on the effects of gravity - or its absence - and ionizing radiation on the evolution, development, and function of living organisms is presented in layman's terms. The book describes the benefits of space biology for basic and applied research to support human space exploration and the advantages of space as a laboratory for scientific, technological, and commercial research.

Driving evolution forward, the Earth's physical environment has challenged the very survival of organisms and ecosystems throughout the ages. With a fresh new perspective, Evolution on Planet Earth shows how these physical realities and hurdles shaped the primary phases of life on the planet. The book's thorough coverage also includes chapters on more proximate factors and paleoenvironmental events that influenced the diversity of life. A team of notable ecologists, evolutionary biologists, and paleontologists join forces to describe drifting continents, extinction events, and climate change -- important topics that continue to shape Earth's inhabitants to this very day. In a world where global change has become an international issue, this book provides a several billion-year evolutionary perspective on what the environment and environmental change means to life.* Provides thorough background information on each topic while introducing cutting-edge research* Features original material solicited from the leading minds in evolutionary biology and geology today* Emphasizes the influence of massive geological forces - continental drift, volcanic activity, sea and tides
This book provides cutting-edge studies and technologies using small fishes, including zebrafish, medaka, and other fishes as new model animals for molecular biology, developmental biology, and medicine. It also introduces eccentric fish models that are pioneering new frontiers of biology. Zebrafish and medaka have been developed as lower vertebrate model organisms because these small fish are easy to raise in the laboratory and are useful for the live imaging of the morphology and activity of cells and tissues in intact animals. By virtue of those specific advantages, fish studies have demonstrated the common features of vertebrates and raised further questions toward understanding the mystery of life. The book consists of four parts: “Development and Cell Biology”, “Homeostasis and Reproduction”, “Clinical Models”, and “Eccentric Fish”. Together they describes the core area of small fish study – often considered mere zoology but which is actually proving to be the universal basis of life. Written by leading scientists, the book helps readers to understand small fishes, inspires scientists to utilize small fishes in their studies, and encourages anyone who wants to participate in the large and fantastic world of small fish.
Now in its third edition the Encyclopedia of Astrobiology serves as the key to a common understanding in the extremely interdisciplinary community of astrobiologists. Each new or experienced researcher and graduate student in adjacent fields of astrobiology will appreciate this reference work in the quest to understand the big picture. The carefully selected group of active researchers contributing to this work are aiming to give a comprehensive international perspective on and to accelerate the interdisciplinary advance of astrobiology. The interdisciplinary field of astrobiology constitutes a joint arena where provocative discoveries are coalescing concerning, e.g. the prevalence of exoplanets, the diversity and hardiness of life, and its chances for emergence. Biologists, astrophysicists, (bio)-chemists, geoscientists and space scientists share this exciting mission of revealing the origin and commonality of life in the Universe. With its overview articles and its definitions the Encyclopedia of Astrobiology not only provides a common language and understanding for the members of the different disciplines but also serves for educating a new generation of young astrobiologists who are no longer separated by the jargon of individual scientific disciplines. This new edition offers ~170 new entries. More than half of the existing entries were updated, expanded or supplemented with figures supporting the understanding of the text. Especially in the fields of astrochemistry and terrestrial extremophiles but also in exoplanets and space sciences in general there is a huge body of new results that have been taken into account in this new edition. Because the entries in the Encyclopedia are in alphabetical order without regard for scientific field, this edition includes a section “Astrobiology by Discipline” which lists the entries by scientific field and subfield. This should be particularly helpful to those enquiring about astrobiology, as it illustrates the broad and detailed nature of the field.
