As the next phase of DTI’s Measurements for Biotechnology (MfB) programme to 2007 gets underway, a large DNA microarray dataset generated by an LGC-led consortium during the first phase is now freely available online at ArrayExpress, a leading public repository managed by the European Bioinformatics Institute (EBI). The sharing of well-annotated data is a primary objective of the Microarray Gene Expression Data (MGED) Society and this repository is stored in accordance with MGED recommendations.
Since the mid-1990s, DNA microarray technology has developed into a major tool for the investigation of global gene expression for all aspects of human disease. The technology is currently being explored for its efficacy in genomic approaches to toxicology. As toxicity is still the major cause of failure in clinical trials, there is strong industry interest in improved models for predictive toxicology.
Dr Carole Foy of LGC’s Bio-Molecular Innovation group said: "This dataset is a significant milestone from the MfB project, ‘Comparability of gene expression measurements,’ completed in 2004. It is a tribute to everyone involved in the consortium - NPL, Human Genome Mapping Project, Oxford Biomedica, Renovo and Royal London Hospital - that other scientists and analysts can now access this valuable data.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
