An experimental model, developed by scientists from VNIIEF in Sarov and their colleagues, ophthalmologists from ‘Mikrokhirugiya Glaza’ [Optical Microsurgery] means that it is possible, quite literally, to see the world with someone else’s eyes. Financial support was given to the researchers for the creation of a model of the human eye by the International Science and Technology Center.
‘The actual initiators of the project were the Moscow-based developers of new artificial crystalline lens models and microsurgeons,’ explains project manager and lead scientist of the VNIIEF Institute of Laser Physics Research Leonid Zykov. ‘The fact is that when treating cataracts they, just as all world specialists, use such an approach widely. A patient’s clouded lens now hinders rather than facilitates sight, is replaced by an artificial crystalline lens, a so-called intraocular lens made of plastic.
‘In addition to the fact that the most suitable crystalline lens has to be selected precisely for the given patient, and they come in all forms and materials and optical parameters, a further problem then arises. After the operation the crystalline lens can shift slightly in the patient’s eye, simply from the reaction of the organism to the implanted body. The doctors themselves have no way of learning how this is reflected on the patient’s sight, on the picture a person sees; they have to rely on the feelings and statements of the patients themselves, a most subjective material to have to work with.

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...
