For decades, scientists have disagreed about the way the brain gathers memories, developing two apparently contradictory concepts. But newly published research by a team of scientists at Rutgers-Newarks Center for Molecular and Behavioral Neuroscience (CMBN) indicates that both models of memory may be partially correct – and that resolving this conflict could lead to new approaches for the treatment of memory disorders such as Alzheimers Disease.
The dispute has centered on how the hippocampus – a structure deep inside the brain – processes new information from the senses and stores it. Some researchers – such as Mark Gluck and Catherine Myers, co-directors of the Memory Disorders Project at the CMBN – have been proponents of "incremental memory," viewing the acquisition of memory as a learning process that occurs over time.
"If you see thunder and lightning occur together once, that may be seen as a coincidence," Myers observed. "But the more often you see them happen at the same time, the more likely you are to remember them as related parts of one event."

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...
