Depression investigators at The Research Institute of University Hospitals of Cleveland have zeroed in on the neurotransmitter serotonin, a brain chemical that regulates emotion. Their tactics: reduce serotonin levels in each study subject to learn who is vulnerable for developing major depression.
This new study, funded by the National Institute of Mental Health, is designed to help scientists better understand the role of serotonin in people who get major depression. By examining the way people feel when serotonin is briefly reduced, UHRI investigators hope to discover new ways of predicting who is at risk for major depression and when treatment with antidepressants can safely be discontinued, according to Pedro L. Delgado, MD.
Dr. Delgado, Chairman of the Department of Psychiatry at UHC and Case Western Reserve University, is the primary investigator for this study. In the study, tests are conducted on healthy participants and upon people having previously suffered from depression. Serotonin levels are temporarily reduced for up to 8 hours and the study team then carefully monitors how the participant feels.

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.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
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.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
