Specialists of one of laboratories at the Department of Chemistry, Astrakhan State University, are sometimes involved in a strange exercise. They take a decent piece of smoked fish or sausage, grind it in a mincing machine, add water, shake it up for about 20 minutes, then filter it and throw away the disagreeable mass, into which the appetizing product was turned into. The remaining solution is analyzed. Here it becomes clear that one should not grudge at all the product used for the analysis. On the contrary, it’s a pity that too little sausage was sliced off, this means that more product would fall to the buyer’s table.
The method developed by the Astrakhan chemists allows to promptly determine, without involving complicated and expensive devices, the amount of phenols contained in meat and fish products, as these are products that are usually smoked. Certainly, the chemists tested their methodology on real objects. Results made strong impression, which was, alas, unpleasant, if not shocking. It has turned out that people simply must no eat some kinds of sausage!
As a matter of fact, any kind of smoking is a risky undertaking from the point of view of health, because smoke as well as liquid smoke is a mixture of various compounds including very dangerous and sometimes toxic ones. They also contain various phenol compounds and even phenol itself, the solution of which is called carbolic acid. It should be noted that hardly anyone would think of drinking it, but as for sausage, it appears that we eat not so little of it!

How herpesviruses win the footrace against the immune system

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...
