A revolutionary new test for identifying people infected with tuberculosis (TB), one of the leading causes of death worldwide, will shortly be launched by Oxford Immunotec Ltd, a new Oxford University spin-off company. The test radically improves the speed and accuracy with which the disease can be identified. It has been developed to replace the existing skin test for TB, which is given to 600,000 UK schoolchildren every year.
Oxford Immunotecs test has come from discoveries made over the last seven years at the University of Oxford by Dr Ajit Lalvani and collaborators at the Nuffield Department of Medicine, John Radcliffe Hospital. A replacement for the 100-year-old skin test is long overdue but, until now, there has not been a better way of diagnosing infection.
The Oxford Immunotec test is based on patented technology which provides a simple and extremely accurate way of studying a person’s cellular immune response to an infection. Every time someone becomes infected with a disease, the body produces specific cells (white blood cells) to fight the infection. The new test looks to see if the body has produced these cells in response to TB and monitors how their numbers change over time. In this way, it is possible to determine if a person is infected and whether they are effectively fighting the infection. This powerful technique can be used not only for diagnosis of infections, but also for prognosis of disease and monitoring of treatment.
Crucially, the Oxford Immunotec test will also make it possible to accurately identify people who are carrying TB infection, but who have not yet gone on to develop disease. Diagnosing and treating infected people before they go on to develop severe disease and infect others is essential to prevent the spread of TB and save lives. TB kills between two and three million people each year, and the death toll is increasing. TB in the UK has risen almost every year for the last 15 years, with 6,500 newly diagnosed cases each year.

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...
