  • A Review of J. Craig Venter's a Life Decoded
    A peer-reviewed electronic journal published by the Institute for Ethics and Emerging Technologies ISSN 1541-0099 17(1) – March 2008 A review of J. Craig Venter’s A Life Decoded Randy Mayes, Duke University Journal of Evolution and Technology - Vol. 17 Issue 1 – March 2008 - pgs 71-72 http://jetpress.org/v17/mayes.htm In the early 1980s, a number of researchers suggested sequencing and mapping the human genome to help the science community better understand diseases and evolution. Following the announcement that the human genome had been sequenced, scientists wrote in peer-reviewed journals that we are not as hardwired as was once believed, and that the sequencing of the genome was just the beginning. Today, researchers have a new set of goals. In popular journalism, however, the science was lost in the shuffle. The media focused more on the dynamics of the conflicting philosophies of the private and public projects. This emphasis is also clear in the titles of several books chronicling the Human Genome Project, all appearing prior to the recent release of Craig Venter’s autobiography, A Life Decoded: My Genome: My Life (2007). Readers will find that Robert Cook-Deegan’s The Gene Wars (1995) and The Common Thread by Sir John Sulston and Georgina Ferry (2002), both written by insiders, are biased towards the philosophy of the public project, a commons approach. Sulston is a socialist who grows runner beans and drives a second hand car. By contrast, Venter travels in Lear jets and conducts business from his yacht. Three other books are more objective.

Industrial Fellow, Manchester Institute of Innovation Research, Alliance Manchester Business School, Manchester University. 2 Senior Visiting Fellow, Institute for the Advanced Study of Sustainability, United Nations University 3. Information System Services, Lancaster University Abstract This article presents the global patent landscape for synthetic biology as a new and emerging area of science and technology. The aim of the article is to provide an overview of the emergence of synthetic biology in the patent system and to contribute to future research by providing a high quality tagged core dataset with 7,424 first filings and 71,887 family members. This dataset is intended to assist with evidence based exploration of synthetic biology in the patent system and with advancing methods for the analysis of new and emerging areas of science and technology. The starting point for the research is recognition that traditional methods of patent landscape analysis based on key word searches face limitations when addressing new and emerging areas of science and technology. Synthetic biology can be broadly described as involving the design, synthesis and assembly of biological parts, circuits, pathways, cells and genomes. As such synthetic biology can be understood as emerging from a combination of overlaps and convergences between existing fields and disciplines, such as biotechnology, genetic engineering, protein engineering and systems biology.

  • Scientists Create Cell Based on Man-Made Genetic Instructions
    25-5-2010 Scientists create cell based on man-m… Scientists create cell based on man•made genetic instructions By David Brown Friday, M ay 21, 2010; A03 Scientists reported Thursday that they have created a cell controlled entirely by man•made genetic instructions •• the latest step toward creating life from scratch. The achievement is a landmark in the emerging field of "synthetic biology," which aims to control the behavior of organisms by manipulating their genes. Although the ultimate goal of creating artificial organisms is still far off, the experiment points to a future in which microbes could be manufactured with novel functions, such as the ability to digest pollutants or produce fuels. Some ethicists fear that the strategy could also be used to produce biological weapons and other dangerous life forms. In a paper published online by the journal Science, researchers from the J. Craig Venter Institute described using off•the•shelf chemicals and the DNA sequence of Mycoplasma mycoides's genes to make an artificial copy of the bacterium's genome. The scientists then transplanted that genome into the cell of a different (but closely related) microbe. The donor genome reprogrammed the recipient cell, which went on to replicate and divide. The result was new colonies of Mycoplasma mycoides. "We think these are the first synthetic cells that are self• replicating and whose genetic heritage started in the computer. That changes conceptually how I think about life," said J. Craig Venter, 63, who gained fame a decade ago as the co•sequencer of the human genome. His institute has laboratories and offices in Rockville and San Diego.

  • Biographical Memoirs
    National Academy of Sciences - Biographical Memoirs http://www.nasonline.org/publications/biographical-memoirs/online-collection.html By Michael P. Filosa Flack Norris (1871-1940) for the November Nucleus, I came across his biographical memoir on the website of the National Academy of Sciences (NAS). This memoir was written by John D. Roberts and was presented to the Academy in 1974, a scant(!) 34 years after his death. The NAS was founded in 1863 by 50 of the most prominent scientists in the United States, and its initial charter was signed by Abraham Lincoln. It is a tradition that each of its members be memorialized in a memoir to the Academy written by a peer (or two). These memoirs are a treasure trove of the history of science. The sole weakness is that they are posthumous and not necessarily, very timely. However, they are quite thorough and a good overview of the scientists, complete with a detailed listing of their major works. During my school years, I was always intrigued with stories about great scientists. Dan Kemp would talk extensively about his thesis advisor, R. B. Woodward, and his works. Those stories about Woodward (1917-1979) and also Gilbert Stork were very influential in my decision to pursue synthetic organic chemistry as a career. Woodward’s memoir was written by Elkan Blout (with assistance from Frank Westheimer) and was published in 2001, a “scant” 22 years after his death. The memoirs are often glowing: “Robert Burns Woodward was the preeminent organic chemist of the twentieth century. This opinion is shared by his colleagues, students and by other distinguished chemists.” Blout includes lengthy commentaries from Sir Derek Barton, Roald Hoffman and Albert Eschenmoser in the memoir.
