ExtremeDB is a freely available web based relational database which integrates general characteristics, genome-proteome information, industrial applications and recent scientific investigations of the seven major groups of 865 extremophillic microorganisms. The search options are user friendly and analyses tools such as Compare and Extreme BLAST have been incorporated for comparative analysis of two or more extremophiles and determining the sequence similarity of a given protein/nucleotide in relation to other extremophiles respectively. The effort put forth herein in the form of database, would open up new avenues on the potential utility of extremophiles in applied research.極限性古細菌・微生物の統一レポジトリ。非情報系研究者に高度なUIを提供する流れの成果
estimation problems on high-dimensional discrete spaces in which the number of possible discrete solutions is immense. In the analysis of biological data or the development of prediction algorithms, this uncertainty should be handled carefully and appropriately.
In this review, I will explain several methods to combat this uncertainty, presenting a number of examples in bioinformatics. The methods include (i) avoiding point estimation, (ii) maximum expected accuracy (MEA) estimations, and (iii) several strategies to design a pipeline involving several prediction methods.

Linear regression of genetic complexity (on a log scale) extrapolated back to just one base pair suggests the time of the origin of life = 9.7 ± 2.5 billion years ago. Adjustments for potential hyperexponential effects would push the projected origin of life even further back in time, close to the origin of our galaxy and the universe itself, 13.75 billion years ago.ゲノム長と片対数グラフから、生命の起源は90億年前(地球形成よりも前)とする説。さりげにENCODEプロジェクトにも言及w 生物活性をメモリ、自己触媒をコーディング要素として哲学ぽい
Evolution of advanced organisms has accelerated via development of additional information-processing systems: epigenetic memory, primitive mind, multicellular brain, language, books, computers, and Internet. As a result the doubling time of human functional complexity has reached ca. 20 years. Finally, we discuss the issue of the predicted "technological singularity" and give a biosemiotics perspective on the increase of life’s complexity.
Why evolvability appears to have increased over evolutionary time is an important unresolved biological question. Unlike most candidate explanations, this paper proposes that increasing evolvability can result without any pressure to adapt.
The insight is that if evolvability is heritable, then an unbiased drifting process across genotypes can still create a distribution of phenotypes biased towards evolvability, because evolvable organisms diffuse more quickly through the space of possible phenotypes.
Furthermore, because phenotypic divergence often correlates with founding niches, niche founders may on average be more evolvable, which through population growth provides a genotypic bias towards evolvability. Interestingly, the combination of these two mechanisms can lead to increasing evolvability without any pressure to out-compete other organisms, as demonstrated through experiments with a series of simulated models.
Thus rather than from pressure to adapt, evolvability may inevitably result from any drift through genotypic space combined with evolution's passive tendency to accumulate niches.
Many approaches to the question have looked for statistical signatures of sequence under selective constraint. However, selection could, for example, be on the process of transcription not the product of transcription. A stronger, or perhaps complementary, approach is to start with a mechanistic hypothesis.
FOXP2 in Europeans, but not in Asians/Africans. Does this mean that Europeans have enrichment conferring a different advantage?
The selected genes have multiple roles in cellular development, signalling, reproduction and immunity. Selection of these genes in Europeans is more likely to reflect local population adaptations to the climate, diet or pathogens that they encountered as their ancestors spread across Europe after splitting from the ancestors of Asian populations.
Runxt Life ? Introduction from Firma 103 on Vimeo.
Runxt Life is a generative music application created for the iOS® platform based on the cellular automaton theory “Conway’s Game of Life” by John Horton Conway.
The ‘game’ is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input from humans. One interacts with the Game of Life by creating an initial configuration and observing how it evolves.
Today a consortium of leading IT providers and three of Europe’s biggest research centres (CERN, EMBL and ESA) announced a partnership to launch a European cloud computing platform. ‘Helix Nebula ‐ the Science Cloud’, will support the massive IT requirements of European scientists, and become available to governmental organisations and industry after an initial pilot phase.
Helix Nebula along with the Cloud Security Alliance, OpenNebula Project and the European Grid Infrastructure (EGI.eu), The commercial partners in this platform are Atos, Capgemini, CloudSigma, Interoute, Logica, Orange Business Services, SAP, SixSq, Telefonica, Terradue, Thales, The Server Labs and T‐Systems, They are working together to establish a federated and secure high‐performance computing cloud platform.
Sundquist explained that he had the above challenges in mind when he started DNAnexus. “We founded the company with a mission to unlock what we believe is a huge potential for DNA-based medicine and biotechnology.” The company is seeking to do that by building a collaborative and scalable platform. The firm has attracted financial support from Google Ventures and TPG Biotech.
One of the key tasks of the Transition Team is to develop the conceptual framework for an integrated platform that links major research traditions with critical policy and human development concerns and can be used to identify priority research questions for Future Earth.
The geography of life on earth lies at the heart of ecology, evolution and the interaction of nature with human society. The spatiotemporal context of individual organisms, populations and species defines their environmental and biotic setting.
<fot size=1>This setting, in turn, drives ecological processes and provides the arena for micro- and macro-evolutionary mechanisms. Geographic data on the distribution of species are also vital for governments, agencies, and companies seeking to develop effective policies, and make sound decisions, regarding land management, health, climate change and biodiversity conservation.
By bringing together all types of information about species distributions, providing model-based integration, and providing a system for users to build upon our knowledge, the Map of Life project hopes to support our community in understanding and saving the world's biodiversity.
A re-invigorated effort to boost African science know-how to solve Africa's challenges has begun. With international funding, the Biosciences eastern and central Africa Hub (BecA-ILRI Hub) based in Nairobi, Kenya and managed by the International Livestock Research Institute (ILRI) is enabling African and international scientists to partner on a wide range of new and exciting research programs. Most of these research programs focus on both animal and crop health for better productivity under challenges including diseases and abiotic stresses.
In just 3 pages the Research Works bill seeks to prohibit open access mandates for federally funded research in the USA thus reverting the open access policy of the National Institute of Health (NIH) in the USA. It was introduced by Darrell Issa on 23 December 2011 and has caused major battles between the academic and publishing industries. The bill has the support of Elsevier, Association of American Publishers and the Copyright Alliance:
HR 3699 will limit American taxpayers in accessing the results of the crucial scientific research they funded. By reversing the growing trend for cooperation and collaboration made possible by the open and rapid sharing of information and research results, this bill will inhibit our ability to exploit scientific discoveries, stifle critical advances in life-saving scientific research, and impede the pace of innovation in all scientific disciplines.

Our results underscore two general considerations for researchers proposing novel types of analysis based on the GO: 1) that GO annotations are often incomplete, potentially in a biased manner, and subject to an “open world assumption” (absence of an annotation does not imply absence of a function), and 2) that conclusions drawn from a novel, large-scale GO analysis should whenever possible be supported by careful, in-depth examination of examples, to help ensure the conclusions have a justifiable biological basis.
Euan Adie and I started the CrowdoMeter project, an analysis of the semantic content of tweets linking to scholarly papers. Because classifying almost 500 tweets is a lot of work, we turned this into a crowdsourcing project.
For this purpose I have created a public repository on Github which contains not only the source code for the CrowdoMeter website, but also all data ? the same dataset made available on figshare.

DNA nanorobot from Wyss Institute on Vimeo.
<fon tize=1>This programmable nanotherapeutic approach was modeled on the body's own immune system in which white blood cells patrol the bloodstream for any signs of trouble. These infection fighters are able to home in on specific cells in distress, bind to them, and transmit comprehensible signals to them to self-destruct.
The DNA nanorobot emulates this level of specificity through the use of modular components in which different hinges and molecular messages can be switched in and out of the underlying delivery system, much as different engines and tires can be placed on the same chassis. The programmable power of this type of modularity means the system has the potential to one day be used to treat a variety of diseases.
We are also aware of the need to tailor general advice about open government data to the legislative frameworks and requirements of different countries. If you would like to be involved in writing a country specific adaptation of the Open Data Handbook, please do get in touch via the mailing list.

I will be bringing the Canadian Drug Product Database to the Hacking Health Hackhaton to play with in RDF format and store in a Virtuoso triplestore. The same technology used to publish Wikipedia according to the Semantic Web standard, the software used by DBpedia project.
For Pfam and Rfam we adopted the use of Wikipedia as the wiki model.
Are wikis the future of biological databases? Well, the answer is yes, and no. They help bridge the vast gap between the amount of human-annotated data compared to unannotated data. Where annotations do exist, the use of wikis can help to improve the annotation and keep it relevant. But, wikis are extremely simple and are unlikely to replace the complex relational organisation of many biological databases.
In September, the United States was one of eight founding governments of the Open Government Partnership,a new multilateral initiative that secures concrete commitments from governments to promote transparency, empower citizens, fight corruption, and harness new technologies to strengthen governance.The President also unveiled the U.S. National Action Plan on Open Government, which detailed steps the United States will take to help meet the initiative’s goals.
Europe’s Large Hadron Collider (LHC), which has been consistently operating since 2009 after a botched grand opening the previous year, is theoretically capable of seeing hints of the Higgs boson, and now the rumor among the physics community is that it’s done just that. A two-part lecture scheduled for Dec. 13 at the European Organization for Nuclear Research (CERN) has the tantalizing title, “Update on the Standard Model Higgs searches.”
Here we present a simulation with a bias potential acting in the directions of collective motions determined by a nonlinear dimensionality reduction method. Ad hoc generated conformations of trans,trans-1,2,4-trifluorocyclooctane were analyzed by Isomap method to map these 72-dimensional coordinates to three dimensions, as described by Brown and co-workers. Metadynamics employing the three-dimensional embeddings as collective variables was applied to explore all relevant conformations of the studied system and to calculate its conformational free energy surface.
The nucleic acid simulation tool (NAST) has been written for this purpose and can be downloaded for free from https://simtk.org/home/nast.

Kepler 22-b, which is about 2.4 times the size of Earth and lies in the so-called "Goldilocks zone", has a relatively comfortable surface temperature of about 22C (72F) and orbits a star not unlike Earth's sun.
But while astronomers believe that it "probably" also possesses water and land, earthlings secretly harbouring hopes that such a planet could potentially host new colonies from our own increasingly overpopulated home may be in for a disappointment.
About 600 light-years from Earth, Kepler 22-b is a considerable trek away while experts are not yet sure if it is made mostly of rock, gas or liquid
Dencity maps population density using circles of various size and hue. Larger, darker circles show areas with fewer people, while smaller, brighter circles highlight crowded cities. Representing denser areas with smaller circles results in additional geographic detail where there are more people, while sparsely populated areas are more vaguely defined.
There were a remarkable amount of talks on connecting SMW with the rest of the Semantic Web, through RDF, SPARQL etc. Cool, SMW is seemingly becoming a natural choice of platform for SemWeb publishing!
The proportion of bio-people were also a bit remarkable. Apart from SNPedia founder Mike Cariaso, there were a whole bunch of others, including Salvadore from the GeneWiki project, Toni .... (and me) .... I guess it reflects how good SMW handles the need to give structure to very heterogenous datasets, so typical for the Life Sciences.
The new database is now available to marketing, business development, competitor intelligence, KOL, medical affairs and related departments in the life sciences sector.
The database currently tags 45,000 individuals working in Synthetic Biology. http://bit.ly/tn1jLa.
Linked data is a powerful approach to sharing information across the web. It is enabling governments to publish their data to better inform and empower citizens, enabling companies to connect information across silos to aid decision making, and enabling developers to combine data from across organizations to deliver better services.

遺伝子決定論に限界があることは、臨床でも(一卵性双生児での遺伝学的病変の転帰が同一ではないことから)、また実験においても(同質の環境下であっても、変異によって同系動物間にさまざまな影響が生じることから)、ずっと以前から明らかだった。そうだとしても、個体の表現型は予測可能かもしれないと考えたB Lehnerたちは、発生中の動物で変異の帰結を直接予測する方法を考案した。
非侵襲的な、蛍光を用いる方法によって、線虫(Caenorhabditis elegans)の胚発生過程での遺伝子発現のゆらぎを監視し、各胚の分子ノイズとその胚に対応する成体の表現型を後ろ向きに比較したのである。そして、密接に関係する遺伝子間に生じる調節補償作用と、シャペロンなどの一般的な調節因子がかかわる調節補償作用が明らかになった。こうした補償の強さによって、動物ごとの成体表現型が予測される。
Ariadne's flagship product is Pathway Studio for the analyses of molecular pathways and disease progression. The software suite comprises an integrated data mining and visualization product "that organizes relevant facts and relationships from large document collections of genes, proteins, cell processes, and diseases," Elsevier said in a statement.

Two use cases, clinical document sections, and the 2010 i2b2/VA NLP Challenge (i.e., problems, tests, and treatments, with their assertions and relations), were used to create examples of such standoff annotation documents, and were successfully validated with the XML schemata provided with both standards. We developed a tool to automatically translate annotation documents from the 2010 i2b2/VA NLP Challenge format to GrAF, and automatically generated 50 annotation documents using this tool, all successfully validated.
RNA-SeQC is a java program which computes a series of quality control metrics for RNA-seq data. The input can be one or more BAM files. The output consists of HTML reports and tab delimited files of metrics data. This program can be valuable for comparing sequencing quality across different samples or experiments to evaluate different experimental parameters. It can also be run on individual samples as a means of quality control before continuing with downstream analysis.
RNA-SeQC is built on the GATK as well as the Picard API.
SLIDE is based on a linear model with a design matrix that models the sampling probability of RNA-Seq reads from different mRNA isoforms. To tackle the model unidentifiability issue, SLIDE uses a modified Lasso procedure for parameter estimation. Compared with deterministic isofor

Siri 試してみた。あれの裏側は wolframAlpha かと思った。readwriteweb.com/archives/apple…
We first ran into Siri nearly two years ago now and since then the company has been on a tear. During this year's SXSW Interactive, we quickly pegged it to run away with the BizSpark Accelerator competition and soon after it was acquired by Apple. Now, a partnership with Wolfram Alpha can really bring Siri to the next level.
The growth of PLoS ONE may have been stellar but it still accounts for only tiny percentage of the total scientific output. It has changed the culture, but by how much? If cost, speed of publication and ease of access were really the primary concerns of working scientists, surely other publishers would have jumped into the market?
This is happening to an extent ? have a look at Nature Publishing Group’s latest title, Scientific Reports ? but these new open access journals still charge a hefty fee to authors for the privilege of publication. Shouldn’t the free market be driving down costs?

Alice is a 1988 Czechoslovak film directed by Jan Švankmajer. Its original Czech title is Něco z Alenky, which means "Something from Alice". It is a free adaptation of Lewis Carroll's first Alice book, Alice's Adventures in Wonderland, about a girl who follows a white rabbit into a bizarre fantasy land. Alice is played by Kristýna Kohoutová. The film combines live action with stop motion animation, and is distinguished by its dark and uncompromising production design.
