Combining research-oriented teaching and interdisciplinary collaboration pays off: Researchers at the University of Konstanz develop a novel spectroscopic approach to investigate hitherto difficult-to-observe protein structures. On “campus.kn”, the online magazine of the University of Konstanz, we report on the new approach and its origin at the interface between chemistry and biology.
Using infrared (IR) spectrosocopy, researchers at the University of Konstanz were able to uncover the interaction between the p53 protein, a tumour suppressor that controls the cell cycle, and poly(ADP-ribose) (PAR) and deoxyribonucleic acid (DNA) at the molecular level.
The nucleic acid-like biopolymer PAR serves as a cellular signal transmitter and helps to regulate protein activity.
By studying the interaction between p53 and PAR, the researchers were able to learn more about molecular reactions to cellular stress in response to, for example, DNA damage, which represents a potential tumour risk.
Their basic research on the processes behind DNA damage is, on the one hand, paramount to understanding how cancer develops and how cells age.
On the other hand, the innovative scientific approach is advancing the research carried out in their field. Their research results were published in issue 9 (21 May 2019) of the scientific journal Nucleic Acids Research by the Oxford University Press.
In a new article published on “campus.kn”, the online magazine of the University of Konstanz, we tell the story of the project’s development, which builds on interdisciplinary linkages especially between early career researchers: https://www.campus.uni-konstanz.de/en/science/uncovering-hidden-protein-structur...

For years, a new synthesis method has been developed at TU Wien (Vienna) to unlock the secrets of "strange metals". Now a breakthrough has been achieved. The results have been published in "Science".
Superconductors allow electrical current to flow without any resistance - but only below a certain critical temperature. Many materials have to be cooled down...

Styrofoam or copper - both materials have very different properties with regard to their ability to conduct heat. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz and the University of Bayreuth have now jointly developed and characterized a novel, extremely thin and transparent material that has different thermal conduction properties depending on the direction. While it can conduct heat extremely well in one direction, it shows good thermal insulation in the other direction.
Thermal insulation and thermal conduction play a crucial role in our everyday lives - from computer processors, where it is important to dissipate heat as...
In order to advance the transfer of research developments from the field of quantum sensor technology into industrial applications, an application laboratory is being established at Fraunhofer IAF. This will enable interested companies and especially regional SMEs and start-ups to evaluate the innovation potential of quantum sensors for their specific requirements. Both the state of Baden-Württemberg and the Fraunhofer-Gesellschaft are supporting the four-year project with one million euros each.
The application laboratory is being set up as part of the Fraunhofer lighthouse project »QMag«, short for quantum magnetometry. In this project, researchers...
