The invention presented here produces, on the contrary, enzyme conjugates, which specifically interact with target DNA: It also provides methods for manufacturing these enzyme conjugates. Using a linker, enzymes are covalently bonded to enzyme conjugates with a specificity anchor. Here the specificity anchor refers to, for example, oligonucleotide derivatives or peptide nucleic acids that, adjacent to the recognition site for the enzyme residue, are characterised by a triplex forming site (TFS) on the target DNA, whereby the specificity anchor and the linker determine in which position on the target DNA and in which distance to the enzyme residue the triplex formation between the TFS of the target DNA and the triplex forming specificity anchor of the conjugate takes place. As a result, the specificity of a enzyme conjugate according to the current invention can be ?programmed? so that ideally only one single recognition site exists on the target DNA for the enzyme conjugate. Even if the recognition site for the conjugate appears more than once, the number of positions in which the target DNA binds with the conjugate is significantly smaller than the number of recognition sites for the unconjugated enzyme.

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...
