Clearance of beta amyloid accumulation within neurons stops memory decline in mice
Researchers at UC Irvine have identified a trigger at the molecular level that marks the onset of memory decline in mice genetically engineered to develop brain lesions – in the form of plaques and tangles – associated with Alzheimers disease. The trigger is a protein called "beta amyloid" that accumulates within neurons in the mices brains. Although several researchers have studied the association between beta amyloid and memory, the UCI research team is the first to identify that early beta amyloid accumulation within neurons is the trigger for the onset of memory decline in Alzheimers.
"This finding has important and useful implications for the pharmaceutical industry in terms of developing drugs that can target beta amyloid as soon as it accumulates within the neurons," said Frank LaFerla, principal investigator of the research project, associate professor of neurobiology and behavior, and co-director of the UCI Institute for Brain Aging and Dementia. "Once the plaques and tangles form, it is too late."

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...
