Biotechnology BIOTECHNOLOGY INTERNATIONAL TRENDS AND PERSPECTIVES BY ALAN T. BULL GEOFFREY HOLT MALCOLM D. LILLY ORGANISATION FOR ECONOMIC CO–OPERATION AND DEVELOPMENT 1 The Organisation for Economic Co–operation and Development (OECD) was set up under a Convention signed in Paris on 14th December 1960, which provides that the OECD shall promote policies designed: − to achieve the highest sustainable growth and employment and a rising standard of living in Member countries, while maintaining financial stability, and thus to contribute to the development of the world economy; − to contribute to sound economic expansion in Member as well as non–member countries in the process of economic development; and − to contribute to the expansion of world trade on a multilateral, non–discriminatory basis in accordance with international obligations. The Member countries of the OECD are Australia, Austria, Belgium, Canada, Denmark, Finland, France, the Federal Republic of Germany, Greece, Iceland, Ireland, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Spain, Sweden, Switzerland, Turkey, the United Kingdom and the United States. The opinions expressed and arguments employed in this publication are the responsibility of the authors and do not necessarily represent those of the OECD. Publié en français sous le titre: BIOTECHNOLOGIE TENDANCES ET PERSPECTIVES INTERNATIONALES © OECD 1982 2 One of the important tasks of the OECD Committee for Scientific and Technological Policy is to follow the emergence of major fields of technology, to debate the various policy issues arising from it, and to help solve those which fall within its Mandate. Thus, I am pleased that this report to OECD on Biotechnology is being made available to the public at large. This work is but the beginning of a more continuous interest of the Committee in a technology that is likely to modify the lives of most people in the OECD Member countries and beyond, through impacts on health, nutrition, energy and the environment. Three factors come together — in my view — to explain the interest which this report has generated in the Committee. First, it is an up–to–date, comprehensive review of prospects in an area of science and technology of major interest to Member countries. A second factor is the conviction of the authors of the report that the successful development of biotechnology depends upon conditions and directions which the Committee has attempted to foster in other sectors of the research system and in other areas of science policy. They are: the need for increased emphasis on inter– and multi–disciplinary research, the close interaction between fundamental research, applied research and engineering and the corresponding need for balanced support of all components of the R&D spectrum, the importance of assessing future opportunities in science and technology and their societal impacts, and the need for integration of science, economic and other policies (such as education and regulation policies). A third feature of this report is its timeliness. Several OECD countries have launched biotechnology plans or policies during the last few years, and they have now to concern themselves increasingly with the international implications of their projects. Other countries are in the process of drafting their first plans. Accordingly, the Committee has agreed to undertake further work on biotechnology. This work will focus on four issues: − Patent Protection in Biotechnology, which among others, will enable individual OECD countries to compare their legal situation to that of others. − Safety and Regulations, which will investigate among other aspects, the problems that might arise in industrial mass production. − Government Policies and Priorities in Biotechnology R&D, which will compare past and present R&D priorities related to biotechnology, and review the national debates and mechanisms that have helped to set these priorities. − Economic Impacts of Biotechnology, an important project that might begin when the other projects are nearing completion. I can only express my hope that the next steps in the Committee’s work on biotechnology will meet with as much interest and success as this first step. Prof. Dr. A.A.Th.M.

  • Biotechnology: Answers to Common Questions
    FSR0030 Biotechnology: Answers to Common Questions Kevin Keener, Assistant Professor of Food Science Thomas Hoban, Professor of Sociology and Food Science N.C. Cooperative Extension Service N.C. State University We are entering the “Century of Biology.” Recent developments in the biological sciences are giving us a better understanding of the natural world. At the same type we are developing new tools that are collectively referred to as “biotechnology.” These help us address problems related to human health, food production, and the environment. Any new technology – particularly one as far-reaching as biotechnology – will generate interest, as well as concerns. Because the science behind biotechnology is complex, misconceptions arise over its impacts and implications. In this publication we will answer questions many people have about biotechnology. These questions are organized along the lines of a news story: what, when, who, where, why, and how. We also provide a list of additional information sources available on the Internet. Our primary focus will be on the uses of biotechnology in agriculture and food production since these appear to be more controversial than other applications (at least up until this time). What is Biotechnology? In its broadest sense, biotechnology refers to the use of living systems to develop products. New scientific discoveries are allowing us to better understand fundamental life processes at the cellular and molecular level. Now we can improve selected attributes of microbes, plants, or animals for human use by making precise genetic changes that were not possible with traditional methods. All living organisms contain genes that carry the hereditary traits between generations.

This work is distributed under Discussions the Creative Commons Attribute 3.0 License. Interactive comment on “Biological catalysis of the hydrological cycle: life’s thermodynamic function” by K. Michaelian K. Michaelian karo@fisica.unam.mx Received and published: 2 June 2011 Complete response to Prof. Schymanski: General Comments In a preliminary response to Prof. Schymanski and the anonymous referee (Michaelian, 2011a), I clarified that my paper neither invokes, nor requires, the “maximum entropy production principle”. The paper simply associates Onsager’s principle (1931) of the coupling of irreversible processes, and the associated increase in entropy production, with the evidence (e.g. Zotin, 1984) for an increase in the amount of coupling of irre- versible biotic processes over the history of life on Earth. The hypothesis of my paper C1907 is that biological irreversible processes also couple with abiotic irreversible processes, in particular, that biology catalyzes the hydrological cycle. This coupling augments the global entropy production of Earth in its solar environment, in accordance with Onsager’s principle. I also suggested in my preliminary response that the particular history of Earth with regard to entropy production would depend very much on par- ticular initial conditions (even microscopic), the kinetics (dependent on the particular forces) and subsequent external perturbations (even microscopic). This dependence arises because the Earth system under the solar photon flux is non-linear and out of equilibrium (Prigogine, 1972). Prof. Schymanski asks; 1) ”What is the mechanism that selects for biota that contribute more to planetary entropy production over such that contribute less but invest more e.g.

  • The Importance of Ecological Memory for Trophic Rewilding As an Ecosystem Restoration Approach
    Biol. Rev. (2019), 94,pp.1–15. 1 doi: 10.1111/brv.12432 The importance of ecological memory for trophic rewilding as an ecosystem restoration approach 1,2,4 1,3 1,2 Andreas H. Schweiger ∗ , Isabelle Boulangeat , Timo Conradi , Matt Davis1,4 and Jens-Christian Svenning1,4 1Section for Ecoinformatics and Biodiversity, Department of Bioscience, Aarhus University, Ny Munkegade 114, 8000, Aarhus C, Denmark 2Plant Ecology, Bayreuth Center for Ecology and Environmental Research (BayCEER), University of Bayreuth, 95440, Bayreuth, Germany 3University Grenoble Alpes, Irstea, UR LESSEM, 2 rue de la Papeterie-BP 76, F-38402, St-Martin-d’H`eres, France 4Center for Biodiversity Dynamics in a Changing World (BIOCHANGE), Aarhus University, Ny Munkegade 114, 8000, Aarhus C, Denmark ABSTRACT Increasing human pressure on strongly defaunated ecosystems is characteristic of the Anthropocene and calls for proactive restoration approaches that promote self-sustaining, functioning ecosystems. However, the suitability of novel restoration concepts such as trophic rewilding is still under discussion given fragmentary empirical data and limited theory development. Here, we develop a theoretical framework that integrates the concept of ‘ecological memory’ into trophic rewilding. The ecological memory of an ecosystem is defined as an ecosystem’s accumulated abiotic and biotic material and information legacies from past dynamics. By summarising existing knowledge about the ecological effects of megafauna extinction and rewilding across a large range of spatial and temporal scales, we identify two key drivers of ecosystem responses to trophic rewilding: (i) impact potential of (re)introduced megafauna, and (ii) ecological memory characterising the focal ecosystem. The impact potential of (re)introduced megafauna species can be estimated from species properties such as lifetime per capita engineering capacity, population density, home range size and niche overlap with resident species.

  • Exploratory Experimentation and Scientific Practice: Metagenomics and the Proteorhodopsin Case
    Forthcoming in: History and Philosophy of the Life Sciences (2007), 29 (3): 335-358 Exploratory experimentation and scientific practice: Metagenomics and the proteorhodopsin case Maureen A. O’Malley Egenis, University of Exeter Byrne House, St Germans Road Exeter, EX4 4PJ, UK ABSTRACT Exploratory experimentation and high-throughput molecular biology appear to have considerable affinity for each other. Included in the latter category is metagenomics, which is the DNA-based study of diverse microbial communities from a vast range of non-laboratory environments. Metagenomics has already made numerous discoveries and these have led to reinterpretations of fundamental concepts of microbial organization, evolution and ecology. The most outstanding success story of metagenomics to date involves the discovery of a rhodopsin gene, named proteorhodopsin, in marine bacteria that were never suspected to have any photobiological capacities. A discussion of this finding and its detailed investigation illuminates the relationship between exploratory experimentation and metagenomics. Specifically, the proteorhodopsin story indicates that a dichotomous interpretation of theory-driven and exploratory experimentation is insufficient, and that an interactive understanding of these two types of experimentation can be usefully supplemented by another category, ‘natural history experimentation’. Further reflection on the context of metagenomics suggests the necessity of thinking more historically about exploratory and other forms of experimentation. Forthcoming

It is a set of techniques that are used to achieve one or more of three goals: to reveal the complex processes of how genes are inherited and expressed, to provide better understanding and effective treatment for various diseases, (particularly genetic disorders) and to generate economic benefits which include improved plants and animals for agriculture, and efficient production of valuable biopharmaceuticals. The characteristics of genetic engineering possess both vast promise and potential threat to human kind. It is an understatement to say that genetic engineering will revolutionize the medicine and agriculture in the 21st future. As this technology unleashes its power to impact our daily life, it will also bring challenges to our ethical system and religious beliefs.

New RNA Research Demonstrates Prebiotic Possibility David W. Ball Creationists and other religious fundamentalists commonly (and erroneously) bring up the issue of abiogenesis as an argument against evolution, claiming that life is too complex to have arisen naturally from simple (non-living) chemicals. Abiogenesis is the development of chemical life from non-living chemicals, and is an active area of research for scientists studying the “Origin Of Life” question. The issue is largely irrelevant as an argument against evolution because evolution deals with what happens after life is formed. It is widely accepted that modern abiogenesis research traces back to the Miller-Urey experiment, performed by Stanley Miller at the University of Chicago (with assistance from Harold Urey) and published in 1953.
