We urgently need international agreements by scientific organizations to limit such publications and an international dialogue on the best approach to preventing recipes for weapons of mass destruction from falling into the wrong hands. The precise genome could potentially be shared with scientists with suitable security assurances. Specific insights - for example, that a key mutation noted in one gene may in part explain the virus's unusual virulence - could be published without disclosing the complete genetic recipe. There are other approaches, however, to sharing the scientifically useful information. These insights could help scientists across the world detect and defend against future pandemics, including avian flu. Proponents of publishing this data point out that valuable insights have been gained from the virus's recreation.

An easier approach would be to modify a conventional flu virus with the eight unique and now published genes of the 1918 killer virus.ДЄ Science staff writer, Jocelyn Kaiser, said, 'Both the authors and Science's editors acknowledge concerns that terrorists could, in theory, use the information to reconstruct the 1918 flu virus.' And yet the journal required that the full genome sequence be made available on the GenBank database as a condition for publishing the paper.

Synthesizing the virus from scratch would be difficult, but far from impossible. No responsible scientist would advocate publishing precise designs for an atomic bomb, and in two ways revealing the sequence for the flu virus is even more dangerous.ДЇirst, it would be easier to create and release this highly destructive virus from the genetic data than it would be to build and detonate an atomic bomb given only its design, as you don't need rare raw materials like plutonium or enriched uranium. The genome is essentially the design of a weapon of mass destruction. Ivanovsky and in 1898 by the Dutch scientist Martinus W. The earliest indications of the biological nature of viruses came from studies in 1892 by the Russian scientist Dmitry I.

The name is from a Latin word meaning slimy liquid or poison. To shed light on how the virus evolved, the United States Department of Health and Human Services published the full genome of the 1918 influenza virus on the Internet in the GenBank database. virus, infectious agent of small size and simple composition that can multiply only in living cells of animals, plants, or bacteria. Like the flu viruses now raising alarm bells in Asia, the 1918 virus was a bird flu that jumped directly to humans, the scientists reported. 'That Cas9 is involved in both processes represents a major step forward in understanding how bacteria discern which DNA to cut and how the enzyme confirms the decision,' said Michael Terns, Distinguished Research Professor of Biochemistry and Molecular Biology.AFTER a decade of painstaking research, federal and university scientists have reconstructed the 1918 influenza virus that killed 50 million people worldwide. In the study, the team describes the basic set of machinery that is required to obtain a specific fragment of viral sequence and insert the fragment in a specific location. 'Our findings implicate Cas9 in the recognition of a secondary, invader-confirmation signal called a PAM.' 'The recognition that this enzyme functions both in capture and in killing provides us with a link between those two processes that we think is involved in ensuring that the process is specific for the virus and avoids potential damage to its own genome,' said Rebecca Terns, a senior research scientist in biochemistry and molecular biology. The UGA study highlights the discovery of a new role of the Cas9 protein in the initial acquisition of the invader sequence. This new tool provides a way to make gene deletions, corrections of mutations and additions of new genes in any genome. This virus identification sequence is kept in a locus commonly known as a CRISPR, short for clustered regularly interspaced short palindromic repeats.Д¬RISPR-associated proteins then use the sequence to recognize and destroy viruses.ДЄ CRISPR-associated protein known as Cas9 destroys invading viral DNA and has been co-opted as a tool for programmable genome editing. The new study, authored by the Terns and postdoctoral research associate Yunzhou Wei in the Franklin College of Arts and Sciences department of biochemistry and molecular biology, was published recently in Genes & Development.ДЄ bacterium gains immunity against a virus through a sophisticated process of acquiring a fragment of the viral DNA and incorporating the sequence into its own genome. They now have identified a key link in how bacteria respond and adapt to foreign invaders. University of Georgia researchers Michael and Rebecca Terns were among the first to begin to study the bacterial immune system.
