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.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
