Research is the guarantor of the quality of knowledge, though it is often not clear how scientific research guarantees the reliability of knowledge. How different can scientific ideals be, and how alike are they despite everything? In her dissertation, the historian of ideas Rangnar Nilsson, University of Gothenburg - Göteborg -, Sweden, examines what fits within the frames of the domains of authorised scientific knowledge.
The author of the dissertation has compared the way researchers in three different disciplines describe and assess quality within their own disciplines. The disciplines studied are political science, literature studies and physics. The aim is to investigate how the internal view on the quality and legitimacy of research and science varies within the research communities and how it can be linked to different conditions of the scientific activity.
The study is based on judgements of what constitutes good and bad science and research in statements of opinions written by subject experts on the work submitted as qualifications by candidates for academic positions. It covers two periods between 1950 and 1995. This allows similarities and differences between the subjects as well as changes and constant features over time to be analysed.
Rangnar Nilsson establishes that the nature of the objects seems to be able to influence the aim towards internationalisation or to reaching out to the public with their work and results.
The physicists consider internationally presented research to be better and more credible, while the literature researchers are much more interested in the researchers' efforts to disseminate their research to the general public in different ways. This difference may be linked to the conditions of the two research areas. The physicians' research objects are equally accessible to researchers around the world, and in time equally inaccessible to the public around the world. This may have contributed to the greater internationalisation of physics (and possibly other areas of natural science). The literature researchers' objects, however, are easier to share with the Swedish general public, as the subject has traditionally devoted itself more to Swedish than foreign literature.
This makes it clear in the dissertation that different factors influence the researchers' own view on the scientific activity and their own work.Title of dissertation: *Good science: How researchers' conceptions of science expressed in peer review documents change in three different disciplines *

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
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...
