A Florida State University scientist used a gene transfer technique to block the expression of a gene associated with clinical depression in a new study of mice that could lead to better treatment of human beings with this condition.
Carlos Bolanos, an assistant professor of psychology and neuroscience, was among a team of researchers that identified the role of a gene called Brain Derived Neurotrophic Factor (BDNF) in the development of social aversion. Mice treated with a transfer technique to block expression of the BDNF gene in a small area of the mid-brain did not develop the aversion despite repeated encounters with aggressive rodents. The study will be published in the Feb. 10 issue of the journal Science.
"Its very exciting because we are slowly but surely identifying mechanisms in the brain underlying psychiatric disorders that have a social withdrawal component, such as social phobia, depression and post-traumatic stress disorder, and that will allow us to find better ways to treat these disorders," Bolanos said. "This study is significant because it gives us an animal model of the disorder and opens up new areas of study."

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
