Search Wars Episode II. Yebol a new search!
YEBOL a youngling from the the Stanford stable, a new search in the block. Yebol's mission is to build human-like world's knowledge base and provide knowledge based search (semantics) and services.
Yebol utilizes a combination of patented algorithms paired with human knowledge to build a Web directory for each query and each user. Instead of the common “listing” of Web search queries, Yebol automatically clusters and categorizes search terms, Web sites, pages and contents.
Yebol allows for a multi-dimensional search result instead of the normal one-dimensional search seen by most web search engines today. This provides a more accurate summary of top sites and categories; a wider array of related search terms; a longer and richer expansion for query results; and a deeper base of links and keywords in search result pages.
Unlike current search platforms, Yebol provides hundreds of easily identified and accessibly categorized results in one easily navigable page. The results not only provide users with a rich search experience, but also help them quickly scan the results to find targeted information. In essence, generate a unique “homepage look” for each search query.
Yebol provides a productive experience for both main types of search – general investigation of a topic and specific target search. For users who want to research and explore a topic, Yebol provides rich information from several dimensions. For users who want a specific type of targeted results, they can quickly focus on their category and navigate to the target.
A search for APOE, top most hit (first) gave a expanded definition Apolipoprotein E - on Wikipedia. Followed by link to GHR, wikigenes, gene cards, AD genetics fact sheet form NIA.
It also gives live context sensitive Twitter streaming too.

Search Wars
very near by....
SEARCH
WARS
There are the Wolfram|Alpha likes that are forming a separatist and slowly gaining power over the Google order. In fact google has managed to bring balance to both with its Google Squared.
While platforms like XTractor, NextBio, Novoseek, GoPubMed, BioMedSearch have specialized in searching biomedical and biological knowledge are even more strengthening the separatists.
Now to see and know who is more powerful, the galactic empire or the separatist? I leave it to the 'Republic' i.e. You users! to judge, in the form of your comments and experiences with such tools and searches! you could even voice your opinions here

Anna University develops bio-defence shield
Of the 12 projects the university submitted, DRDO has approved four and allocated Rs 88 lakh as the first instalment. "The projects are research for bio-defence against pathogens and toxins, development of membranes for gas and organic vapour separation, development of novel anti-fouling nano and ultra filtration membranes (these membranes will prevent the solider from imbibing nano-sized toxins) and development of alternative source for bio-diesel from non-edible oils," D Mohan, a senior scientist with Anna University told the press.
The most important among these is the research on development of bio-defence. "The threat of biological warfare is real, as enemies can unleash bacterial and viral pathogens resistant to known drugs. Even while trying to develop drugs against these pathogens, we have to develop new categories of probiotic microbes, considered good microbes, to resist and overpower toxic microbes,' said K Sankaran, a biotechnologist involved in the project, said.
He added that research is on to develop prevention systems. "We are developing sophisticated remote sensing systems to identify the probable nature and signature of the toxins that the enemies could use. We are also looking at microbes which could be used to negate the effects of a biological attack."
An effective mask against such toxic materials would be a membrane under development that can keep out noxious gases from inhalable air. "This membrane will be used in gas masks. Our challenge is to allow oxygen in and keep harmful and organic vapours out. We have the expertise in membrane technology and we hope to successfully complete the project soon," D Mohan said.
The team developing the membrane is also involved in the research on anti-fouling nano and ultra filtration membranes. "Bio-fouling, the formation of a mucous-like membrane over objects kept in water for long duration, is the main reason for damage of membranes in treatment plants. We need to develop a membrane which can prevent bio-fouling and can perform consistently. Our soldiers, who are camping in extreme conditions, do not get good quality drinking water. With the development of these membranes, the efficiency of water treatment plants in extreme condition will improve," Mohan said.
Anna University is also developing cost-effective bio-diesel from non-edible oil. The aim of this research is to bring down the cost of fueling military vehicles.

An ontology that bridge biological and computational spheres in bioinformatics
IMGT-ONTOLOGY manages the immunogenetics knowledge through diverse facets relying on seven axioms, ‘IDENTIFICATION’, ‘DESCRIPTION’, ‘CLASSIFICATION’, ‘NUMEROTATION’, ‘LOCALIZATION’, ‘ORIENTATION’ and ‘OBTENTION’, that postulate that objects, processes and relations have to be identified, described, classified, numerotated, localized, orientated, and that the way they are obtained has to be determined. These axioms constitute the Formal IMGT-ONTOLOGY, also designated as IMGT-Kaleidoscope.
These axioms have been essential for the conceptualization of the molecular immunogenetics knowledge and for the creation of IMGT. Indeed all the components of the IMGT integrated system have been developed, based on standardized concepts and relations, thus allowing IMGT to bridge biological and computational spheres in bioinformatics. The same axioms can be used to generate concepts for multi-scale level approaches at the molecule, cell, tissue, organ, organism or population level, emphasizing the generalization of the application domain. In that way the Formal IMGT-ONTOLOGY represents a paradigm for the elaboration of ontologies in system biology.

"Modern bio-science is incredibly interdisciplinary now," Thanks-The life sciences are thriving
There was a time when bio-science was the Cinderella science: meticulous, certainly, and worthwhile, but far from glamorous. All that changed in 2003, when the sequencing of the human genome was completed.
Now masses of data and the potential for radical technologies are attracting the best graduates in chemistry, physics, engineering and maths. And bio-science offers more than intellectual curiosity, explains Professor Sir David Read, Biological Secretary and Vice-President of the Royal Society. "It's the human factor," he says. "Cross-disciplinary approaches are addressing many of the major threats to humanity: disease prevalence, antibiotic-resistant micro-organisms, avian flu, the threats to the environment associated with climate change."
The biological sciences are as varied, and sometimes as confusing, as life itself, taking in such disparate disciplines as neuroscience and taxonomy, environmental science and microbiology, physiology and biochemistry. At Cambridge University alone, there are 21 life-science departments.
What is exciting many dons at the moment is omics, or systems biology, which is allowing study to shift from single genes or proteins to how they work together in biological systems.
"The omics system is producing massive amounts of data that we have trouble finding people to make sense of," says Dr David Sargan, director of graduate education in the life sciences at Cambridge.
Mathematicians, physicists, chemists and engineers are all being brought in. "Modern bio-science is incredibly interdisciplinary now," says Professor Paul Freemont, head of molecular bio-sciences at Imperial College London.
Systems biologists are building mathematical models that simulate the living cell, synthetic biologists are redesigning biological systems, chemical biologists are probing living systems at the chemical level, and physicists and engineers are bringing imaging wizardry to bear in biology, from the molecular to the cellular level.
"The biological sciences are going through a revolution," says Professor Freemont. "It's very exciting in the life sciences right now. Students from other disciplines find it fascinating: they see this wonderful opportunity to develop new strands of science."

GenBank celebrates 25 years of service
Leading scientists discuss DNA database at April 7-8 Meeting
For a quarter century, GenBank has helped advance scientific discovery worldwide. Established by the National Institutes of Health (NIH) in 1982, the database of nucleic acid sequences is one of the key tools that scientists use to conduct biomedical and biologic research. Since its creation, GenBank has grown at an exponential rate, doubling in size every 18 months. In celebration of this vital resource and its contribution to science over the last 25 years, the National Center for Biotechnology Information, National Library of Medicine (NLM), NIH, is holding a two-day conference on GenBank.
The conference will take place April 7-8, 2008 at the Natcher Conference Center on the main NIH campus in Bethesda, Maryland. For details on the meeting, see the conference Web site, at http://www.tech-res.com/GenBank25. The conference is open to the public and also will be available via live and archived webcast; the April 7 proceedings can be viewed at http://www.videocast.nih.gov/summary.asp?live=6670 and the April 8 proceedings at http://www.videocast.nih.gov/summary.asp?live=6671.
The conference will bring together a slate of world-renowned scientists in molecular biology, genetics, bioinformatics and other areas to discuss GenBank's applications, the discoveries it has enabled, its history, and future directions. Speakers include Rich Roberts, Ph.D., a Nobel Prize winner for his discoveries of split genes, and currently Chief Scientific Officer at New England BioLabs; Sydney Brenner, Ph.D., a Nobel Prize winner for his work on genetic regulation of organ development and programmed cell death, and currently a professor at the Salk Institute; Francis Collins, M.D., Ph.D., who led the Human Genome Project and is Director of NIH's National Human Genome Research Institute; and Craig Venter, Ph.D., who led the private-sector effort to sequence the human genome and is President of the J. Craig Venter Institute. More than a dozen other eminent scientists will be speaking; the full list of presenters can be viewed at the GenBank conference Web site.
"Each day, researchers across the world submit tens of thousands of sequences to GenBank and collaborating databases in Europe and Japan," said Donald A. B. Lindberg, M.D., Director of the National Library of Medicine. "Because of these contributions, GenBank has become an essential tool for molecular biology. The National Library of Medicine is proud to partner with the research community in making this valuable resource available."
Rich Roberts, Ph।D., Chief Scientific Officer at New England BioLabs, commented, "GenBank has provided a foundation upon which much of contemporary biology is now based. It is becoming almost impossible to conceive of any serious biological study of a new organism that does not begin with the determination of its DNA sequence, which of course must be stored in GenBank." Roberts, one of the early proponents of the database, added, "the availability of this wealth of sequence information in a single repository is something we could only dream about in 1979 at the Rockefeller Conference that led to its creation and which we could not imagine being without today."
