Inspired by Biology:
Scientists have long desired to create synthetic systems that function with the precision and efficiency of biological systems. Using new techniques, researchers are now uncovering principles that could allow the creation of synthetic materials that can perform tasks as precise as biological systems. To assess the current work and future promise of the biology-materials science intersection, the Department of Energy and the National Science Foundation asked the NRC to identify the most compelling questions and opportunities at this interface, suggest strategies to address them, and consider connections with national priorities such as healthcare and economic growth. This book presents a discussion of principles governing biomaterial design, a description of advanced materials for selected functions such as energy and national security, an assessment of biomolecular materials research tools, and an examination of infrastructure and resources for bridging biological and materials science. A long time has passed since the war act on Cancer declared by former USA president Nixon, almost half a century ago. Today, after so many years of feverish research and uncountable efforts worldwide, the end of the war appears far as ever, whereas the fight is leading researchers to newer and newer battlefronts while frontiers in bioscience are continuously being surpassed. In this scenario, "The Selfish Cell" is a script record of the most important strategic points gathered during these years of war, with the goal to provide solid ground onto which step ahead for future assaults against this terrible disease. At the same time, it is an attempt to shift the debate on cancer toward a more peaceful and possibly productive semantic terrain, where to reflect with the aid of superior wisdom to finally get out of that terrible chaos of fight and death dominating our days. In this perspective, "The selfish cell" becomes an occasion for reflecting over our human selfishness limits and their consequences both on our social and natural environment.
Recombination and Meiosis
Once per life cycle, mitotic nuclear divisions are replaced by meiosis I and II – reducing chromosome number from the diploid level to a haploid genome and recombining chromosome arms by crossing-over. In animals, all this happens during formation of eggs and sperm – in yeasts before spore formation. The mechanisms of reciprocal exchange at crossover/chiasma sites are central to mainstream meiosis. To initiate the meiotic exchange of DNA, surgical cuts are made as a form of calculated damage that subsequently is repaired by homologous recombination. These key events are accompanied by ancillary provisions at the level of chromatin organization, sister chromatid cohesion and differential centromere connectivity. Great progress has been made in recent years in our understanding of these mechanisms. Questions still open primarily concern the placement of and mutual coordination between neighboring crossover events. Of overlapping significance, this book features two comprehensive treatises of enzymes involved in meiotic recombination, as well as the historical conceptualization of meiotic phenomena from genetical experiments. More specifically, these mechanisms are addressed in yeasts as unicellular model eukaryotes. Furthermore,evolutionary subjects related to meiosis are treated.
Bioinformatics and Systems Biology
Collaborative research in bioinformatics and systems biology is a key element of modern biology and health research. This book highlights and provides access to many of the methods, environments, results and resources involved, including integral laboratory data generation and experimentation and clinical activities. Collaborative projects embody a research paradigm that connects many of the top scientists, institutions, their resources and research worldwide, resulting in first-class contributions to bioinformatics and systems biology. Central themes include describing processes and results in collaborative research projects using computational biology and providing a guide for researchers to access them. The book is also a practical guide on how science is managed. It shows how collaborative researchers are putting results together in a way accessible to the entire biomedical community.Click here to go to the site please click atleast 2 ads in our site to continue our service by Helping Hands
