The Genetic Code and the Origin of Life
Early Thoughts on RNA and the Origin of Life The full impact of the essential role of the nucleic acids in biological systems was forcefully demonstrated by the research community in the 1950s. Although Avery and his collaborators had identified DNA as the genetic material responsible for the transformation of bacteria in 1944, it was not until the early 1950s that the Hershey-Chase experiments provided a more direct demonstration of this role. Finally, the structural DNA double helix proposed by Watson and Crick in 1953 clearly created a structural frame work for the role of DNA as both information carrier and as a molecule that could undergo the necessary replication needed for daughter ce...
Strategies of Life Detection
This book collects papers presented at a workshop taking an interdisciplinary look at methods designed to detect life on other planets. It serves as a reference to scientists and instrument developers working in the field of in-situ and remote life detection.
The Spark of Life
The authors examine the enduring mysteries surrounding life's origin: did life arise on Earth or on some other planet? What did the earliest primitive organisms look like? Were they based on RNA, DNA, or on something we would hardly recognize today? They explore the latest research - in fields ranging from molecular biology to astronomy - on questions surrounding life's origins.
Geology and Habitability of Terrestrial Planets
Given the universal interest in whether extraterrestrial life has developed or could eventually develop, it is vital that an examination of planetary habitability go beyond simple assumptions. This book has resulted from a workshop at the International Space Science Institute (ISSI) which brought together experts to discuss the multi-faceted problem of how the habitability of a planet co-evolves with the geology of the surface and interior, the atmosphere, and the magnetosphere.
Astrobiology: Future Perspectives
Astrobiology, a new exciting interdisciplinary research field, seeks to unravel the origin and evolution of life wherever it might exist in the Universe. The current view of the origin of life on Earth is that it is strongly connected to the origin and evolution of our planet and, indeed, of the Universe as a whole. We are fortunate to be living in an era where centuries of speculation about the two ancient and fundamental problems: the origin of life and its prevalence in the Universe are being replaced by experimental science. The subject of Astrobiology can be approached from many different perspectives. This book is focused on abiogenic organic matter from the viewpoint of astronomy and ...
From Fossils to Astrobiology
From Fossils to Astrobiology reviews developments in paleontology and geobiology that relate to the rapidly-developing field of Astrobiology, the study of life in the Universe. Many traditional areas of scientific study, including astronomy, chemistry and planetary science, contribute to Astrobiology, but the study of the record of life on planet Earth is critical in guiding investigations in the rest of the cosmos. In this varied book, expert scientists from 15 countries present peer-reviewed, stimulating reviews of paleontological and astrobiological studies. The overviews of established and emerging techniques for studying modern and ancient microorganisms on Earth and beyond, will be valuable guides to evaluating biosignatures which could be found in the extraterrestrial surface or subsurface within the Solar System and beyond. This volume also provides discussion on the controversial reports of "nanobacteria" in the Martian meteorite ALH84001. It is a unique volume among Astrobiology monographs in focusing on fossil evidence from the geological record and will be valuable to students and researchers alike.
Caring is Sharing — Exploiting the Value in Data for Health and Innovation
Modern information and communication technologies make it easier for individuals to be involved in their own health and social care. They also facilitate contact between individuals and service providers and deliver more efficient tools for healthcare staff. Artificial Intelligence (AI) promises to bring even more benefits in the future, with more effectiveness and the provision of decision support. This book presents the proceedings of the 33rd Medical Informatics Europe Conference, MIE2023, held in Gothenburg, Sweden, from 22 to 25 May 2023. The theme of MIE2023 was ‘Caring is Sharing – Exploiting Value in Data for Health and Innovation’, stressing the increasing importance of sharin...
Surviving 1000 Centuries
The circumstances that will shape the long-term future of our planet will be constrained by what is physically possible and what is not. This full color book provides a quantitative view of our civilization over the next 100,000 years, in comparison to the 40-60,000 years it took for modern humans to emerge from Africa, on the basis of contemporary scientific and technological knowledge. The evolution of the Earth’s atmosphere and the origin of water are highlighted as the most important factors for the emergence and the development of life. The authors consider both cosmic and natural hazards, pointing out that scientific information provided by satellites and communication systems on the ground could prevent many unnecessary casualties by forward planning and the installation of elementary precautions. The Earth’s evolving climate is considered, showing how greenhouse gases have played an important role in the past climate, whereas human industrial and agricultural emissions will greatly impact our future.
