□ RNA-Seq Mapping and Detection of Gene Fusions with a Suffix Array Algorithm
>> http://t.co/71SFLXhY
we implemented an RNA-Seq mapping pipeline within the LifeScope software. We introduced new features including filter and junction mapping, annotation-aided pairing rescue and accurate mapping quality values. We combined this pipeline with a Suffix Array Spliced Read (SASR) aligner to detect chimeric transcripts. Performing paired-end RNA-Seq of the breast cancer cell line MCF-7 using the SOLiD system, we called 40 gene fusions among over 120,000 splicing junctions.

GPGPU: Supercalculator for Bigdata / Bioinformatics
General-Purpose computation on Graphic Processing Units:
Les analyses sont réalisées sur des couples gène//SNP mais chaque analyse reste indépendante. Ceci est donc un problème parfaitement adapté à la parallélisation. Trois semaines de développement supplémentaires ont été nécessaires pour traduire l’implémentation initiale en C et récrire les tests statistiques sous forme de kernel OpenCL.
Les résultats sont maintenant générés en moins de 2h (sur un simple portable doté d’une NVIDIA GeForce GT 330M). La quantité de jeux de données n’est donc plus un problème, le patron est content et je conserve mon emploi
De nombreux problèmes liés à la bioinformatique sont parallélisables mais la technologie GPGPU n’est pas encore très répandue dans le domaine. Les langages de bas niveau utilisés par les kernels en sont sans doute la cause principale.

□ Global Next Generation Sequencing (NGS) Market Worth $2,343 Million by 2016.
>> http://t.co/iHnhP8Bb
The global NGS market was valued at $842.5 million in the year 2011, growing at a CAGR of 22.7% from 2012 to 2016. North America commanded the largest share of 51.8% of the overall NGS technology market in 2011.
The Next Generation Sequencing Market is dynamic and innovative; it is also paving its ways into the labs which were previously not involved in sequencing. High pace of NGS research is likely to boost the market for personal genome sequencing in the coming years. Manufacturers predominantly have an inclination towards diagnostic applications both as a supplier and manufacturer. Key players in this market include Illumina (U.S.), Life Technologies (U.S.), 454 Roche (Switzerland), Oxford Nanopore Technologies (U.K.), and Pacific Biosciences (U.S.).

Bayesian method to predict individual SNP genotypes from gene expression data
we developed a Bayesian approach to predict SNP genotypes that is based only on RNA expression data. We show that predicted genotypes can accurately and uniquely identify individuals in large populations. When inferring genotypes from an expression data set using eQTLs of the same tissue type (but from an independent cohort), we were able to resolve 99% of the identities of individuals in the cohort at Padjusted ? 1 × 10－5.
We discuss the implications of deriving genotypic information from RNA data deposited in the public domain.

Researchers from Mount Sinai School of Medicine have developed a method to derive enough DNA information from non-DNA sources -- such as RNA -- to clearly identify individuals whose biological data are stored in massive research repositories. The approach may raise questions regarding the ability to protect individual identity when high-dimensional data are collected for research purposes.

New paper: On-farm dynamic management of genetic diversity: the impact of seed diffusions and seed saving practices on a population-variety of bread wheat http://ow.ly/1izOQ3
Since the domestication of crop species, humans have derived specific varieties for particular uses and shaped the genetic diversity of these varieties. Here, using an interdisciplinary approach combining ethnobotany and population genetics, we document the within-variety genetic structure of a population-variety of bread wheat (Triticum aestivum L.) in relation to farmers’ practices to decipher their contribution to crop species evolution.
Using 19 microsatellites markers, we conducted two complementary graph theory-based methods to analyze population structure and gene flow among 19 sub-populations of a single population-variety [Rouge de Bordeaux (RDB)]. The ethnobotany approach allowed us to determine the RDB history including diffusion and reproduction events. We found that the complex genetic structure among the RDB sub-populations is highly consistent with the structure of the seed diffusion and reproduction network drawn based on the ethnobotanical study.

□ Research that Pays Off: Experts Make the Case for Federal R&D Spending in Capitol Hill Briefings

The Human Genome Project, funded by the federal government at a cost of $5.6 billion (in 2010 dollars) over 13 years, has had a fundamental impact on areas as diverse as human health, agriculture, forensics, and veterinary medicine, with an economic payoff in 2010 alone of $67 billion, according to a study by the Battelle Memorial Institute.
The cumulative impact of the human genome sequencing effort from 1988 to 2010 was estimated at $796.3 billion, with $243.9 billion in personal income for U.S. workers and federal tax revenues of $48.9 billion, far more than the $5.6 billion federal investment in the project.

We describe a method to generate random musical compositions from these networks and find that scores generated in this manner are also perceived to be "good" and are qualitatively similar to the specific score from which the generating network was produced.

A study titled "Spatial Classification of Youth Physical Activity Patterns" shows, for example, that while rural youth get the largest proportion of their physical activity while at school, urban and suburban youth are most active when commuting. Not only does this finding suggest that the walk to school might be just as important to some children's health as is the physical education they receive as part of the school curriculum, it is also important given that adolescent health behaviors are predictive of behaviors in adults.
