Findings may lead to new drug targets for treating schizophrenia
A mouse study reported in this weeks Science magazine shows that three drugs, each acting on a different chemical transmitter in the brain, all produce the same schizophrenia-like symptoms by acting on a single "master molecule" in the brain.
The findings, reported by researchers at Rockefeller University with collaboration from three pharmaceutical and biotech companies, provides, for the first time, a cellular model detailing how this crucial protein, known as DARPP-32, interacts with multiple neurotransmitter systems to produce behavior.
The scientists demonstrate that DARPP-32 acts like the thin neck in an hourglass, through which all signals taken into a nerve cell must pass and be processed, producing a wide variety of biochemical reactions. In this case, three different drugs of abuse, LSD, PCP ("angel dust") and amphetamine, work on three different neurotransmitters, serotonin, glutamate, and dopamine, respectively. All three drugs, which are classified as psychotomimetics or psychostimulants, are processed within the DARPP-32 hourglass neck through the same pathway, thus producing very similar physiological symptoms.

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...
