Developed by LGC as part of the DTI-funded Measurements for Biotechnology (MfB) programme 2004-2007, this innovative approach is the first DNA-based PT scheme able to provide test materials applicable to a significantly wide range of sectors, beneficial to analysts working in clinical, pharmaceutical, forensic, academic and public health laboratories. LGC has established a reputation for setting up and running successful PT initiatives and, as the UK’s National Measurement Institute for chemical and biochemical analysis, promotes international standards for analytical measurement for use in trade, industry, academia and government.
The new scheme encompasses DNA extraction from a proprietary generic matrix and Q-PCR quantification of extracted samples. Participants will be provided with synthetic analytes and matrices, together with target-specific reagents for real-time PCR quantification. The scheme will support a range of detection chemistries and platforms and will operate in accordance with the principles of ILAC Guide 13 and ISO Guide 43-1.
PT schemes enable laboratories to monitor and improve analytical measurements by providing an external quality assessment system to complement their own internal quality control processes. Participation in a PT scheme is integral to laboratory accreditation and often supports regulatory requirements, such as the UK Environment Agency’s Monitoring Certification Scheme (MCERTS).
On announcing the new scheme, Dr John Marriott, Director of Analytical Technology at LGC, and Government Chemist, said: "As the first cross-sectoral DNA-based PT scheme it is a valuable aid to good quality measurements in the technically difficult field of quantitative DNA analysis. Participation in the scheme will help analysts to pinpoint any area of weakness in their procedures and set-up.”

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
