The scientists examine several risk groups. One consists of 10-year-olds born at the University Hospital Jena whose mothers had treatment with glucocorticoids during pregnancy. Two other groups are being followed up by psychologists at the University of Leuven in Belgium and include two-year-olds and 25-year-olds whose mothers suffered from stress during pregnancy. „A unique group studied at the Academic Medical Centre, University of Amsterdam includes persons born in Holland during the Dutch „Hunger Winter“, of 1944/45,” reported Prof. Schwab.Scientists involved in the project use state-of-the art neuropsychological, neurophysiological, and MRI methods to analyse and compare biological and real age of the brain. The biotechnology companies Life Length in Madrid and Biocrates in Innsbruck measure biological age in chromosomes and screen blood samples to determine metabolic blood markers of age. “Environmental factors such as exposure to stress hormones or malnutrition during pregnancy change the readout of genetic information permanently,” reported Matthias Platzer, Head of Genome Analysis at the Leibniz Institute for Age Research in Jena. „These epigenetic processes significantly change stress sensitivity for the rest of life,“ explained Prof Schwab. „Increased stress sensitivity makes one vulnerable to age-related diseases such as stroke and depression,“ he added.

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.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
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...
