There may be new treatments for stroke, migraine, Alzheimer’s and other brain disorders, thanks to the discovery of a mechanism for regulating brain blood flow made by researchers at the University of British Columbia.
Scientists found that astrocytes -- cells that surround nerve cells and all blood vessels in the brain -- have a primary role in regulating blood flow within the brain, and hold promise as a target for new therapies. The findings of the two-year study funded by the Canadian Institutes of Health Research (CIHR) and the Canadian Stroke Network were published this week in Nature by UBC post-doctoral fellow Sean Mulligan and Brian MacVicar, a professor in the Brain Research Centre and the Dept. of Psychiatry at UBC and an investigator with the Vancouver Coastal Health Research Institute (VCHRI).
Using a new technique that they developed to study brain blood flow, Mulligan and MacVicar found that a rise of calcium within the astrocytes instructs the blood vessels to constrict, which alters blood flow.

In the field of nanoscience, an international team of physicists with participants from Konstanz has achieved a breakthrough in understanding heat transport
Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
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...
