While searching for biological markers for suicide risk, a Viennese research team has gained new insights into the relationship between environmental factors and genetics. Traumatic childhood experiences play an essential role and leave traces in the brain. To a large extent, suicide is a taboo ...
Major population study investigates the interplay between genetics, educational attainment and cardiovascular disease
A German and British research team lead by the Technical University of Munich (TUM) has examined the interplay between genetics, cardiovascular disease and educational attainment in a major population study. Genetic variants which had been linked to educational attainment in other studies were ...
Molecular similarities in mice and humans exposed to trauma
Post-traumatic stress disorder (PTSD) is a mental illness that can develop after experiencing a traumatic event. Greater awareness of PTSD emerged when large numbers of soldiers returning from the Iraq war reported symptoms. Other traumatic events such as experiencing childhood or sexual abuse, a ...
Researchers regulate the activity of RNA molecules
Messenger RNA molecules contain genetic information and thus control the synthesis of proteins in living cells. Biochemists at the University of Bayreuth and the University of Bonn have now discovered a way to regulate this process which is central to gene expression: Certain actinobacteria ...
So far, development has been mainly based on a trial-and-error approach. But a novel method might help save a lot of time. A new strategy for designing light-sensitive proteins has been developed by researchers at Ruhr-Universität Bochum (RUB). Such proteins, also known as optogenetic tools, can ...
Engineers have mimicked the human brain with an electronic chip that uses light to create and modify memories
Researchers from RMIT University drew inspiration from an emerging tool in biotechnology - optogenetics - to develop a device that replicates the way the brain stores and loses information. Optogenetics allows scientists to delve into the body's electrical system with incredible precision, using ...
The University Hospital Bonn plans to have a stronger focus on pharmacogenetics – thus emphasising the influence of genetic characteristics on the effect of medications. This idea embodies the approach for personalised medicine. To integrate extensive pharmacogenetic analysis into the clinical ...
Margarita Salas named European Inventor Award 2019 finalist
The European Patent Office (EPO) announces that Spanish scientist and university professor Margarita Salas Falgueras has been nominated for the European Inventor Award 2019 for her pioneering invention that enables DNA tests to reconstruct full genomes from small samples such as a single hair ...
The European Patent Office (EPO) announces the 15 finalists nominated for the European Inventor Award 2019. The Award, now in its 14th year, celebrates the genius and creativity of inventors and inventor teams for their contributions to scientific and technological progress, their role in ...
How the immune system distinguishes between self molecules and non-self molecules such as those from pathogens
A team led by the Freiburg biologists Prof. Dr. Wolfgang Schamel and Prof. Dr. Wilfried Weber conducted an experiment in which they controlled the duration of the interaction of a specific protein with T cells, a type of white blood cells, thereby showing how the immune system differentiates ...
