MIT technique is noninvasive
MIT scientists have developed a new dye that could offer noninvasive early diagnosis of Alzheimers disease, a discovery that could aid in monitoring the progression of the disease and in studying the efficacy of new treatments to stop it.
The work will be published in the Aug. 26 issue of Angewandte Chemie.
Today, doctors can only make a definitive diagnosis of Alzheimers-currently the fourth-leading cause of death in the United States-through a postmortem autopsy of the brain. "Before you can cure Alzheimers, you have to be able to diagnose it and monitor its progress very precisely," said Timothy Swager, leader of the work and a professor in MITs Department of Chemistry. "Otherwise its hard to know whether a new treatment is working or not."

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...
