BIBI automates DNA sequence analysis for bacterial identification in the clinical field. BIBI relies on the use of BLAST and CLUSTAL W programs applied to different subsets of sequences extracted from GenBank. These sequences are filtered and stored in a new database, which is adapted to bacterial identification. For further details refer : http://umr5558-sud-str1.univ-lyon1.fr/ lebibi/lebibi.cgi

Two Texas A&M University researchers have developed a computational tool that will help scientists more accurately study complex units of clustered genes, called operons, in bacteria. The tool, which allows scientists to analyze many bacterial genomes at once, is more accurate than previous methods because it starts from experimentally validated data instead of from statistical predictions, they say. The researchers hope their tool will lead to a better understanding of the complex genetic mechanisms involved in a cell’s functioning. “Eventually, we want to try to improve our tool to make it better and more accurate,” Sze said. “Although our tool can analyze a lot of bacteria at the same time, it compares each bacterium to E. coli separately. So the ultimate goal would be to develop a tool that will analyze them all together.” Do you want to know more?

Integrative Visual Analysis Tool for Biological Networks and Pathways Already blogging on the topic Structured Digital Abstracts - Easier Literature Searching dicussing the inportance of networks in the form of interactions, and further in several others about visualization tools, here is one more. The essence of a living cell is adaptation to a changing environment, and a central goal of modern cell biology is to understand adaptive change under normal and pathological conditions. Because the number of components is large, and processes and conditions are many, visual tools are useful in providing an overview of relations that would otherwise be far more difficult to assimilate. Historically, representations were static pictures, with genes and proteins represented as nodes, and known or inferred correlations between them (links) represented by various kinds of lines. The modern challenge is to capture functional hierarchies and adaptation to environmental change, and to di...

The International Conference in Trends for Scientific Information Professionals Habitual attendees say that "it is the meeting to which they go to spot the trends, as well as the meeting that provides unparalleled opportunities for networking" Trends and networking will be high on the Nice agenda in October 2008. The ICIC meeting covers trends in the field of scientific and professional information with an impressive line-up of significant figures in the information world. Among the topics that will be covered and discussed by the 22+ speakers are: Tools for Competitive Intelligence ( e.g., mining tools, visualisation tools, analysis tools, etc ) Challenges for the information community over the next five years Changes in the information environment for patents, innovation and intellectual property Trends in Search Engines and Information Retrieval ( also see ) Case Studies in Data and Content Integration
