Background: With the passing of Jorg Langowski 6 May 2017 in a sailplane accident, the scientific community was deprived of a strident and effective voice for DNA and chromatin molecular and computational biophysics, for open access publishing and for the creation of effective scientific research networks. Methods: Here, after reviewing some of Jorg's key research contributions and ideas, we offer through the personal remembrance of his closest collaborators, a deep analysis of the major results of his research and the future directions they have engendered. Conclusions: The legacy of Jorg Langowski has been to propel a way of viewing biological function that considers living systems as dynamic and in three dimensions. This physical view of biology that he pioneered is now, finally, becoming established also because of his great effort.

Agonist-controlled competition of RAR and VDR nuclear receptors for heterodimerization with RXR is manifested in their DNA binding

Balint Reho, Lina Fadel, Peter Brazda, Anass Benziane, Eva Hegedus, Pialy Sen, Theodorus W. J. Gadella, Katalin Toth, Laszlo Nagy, Gyorgy Vamosi

Summary: We found that nuclear receptors (NRs) compete for DNA binding in a ligand-dependent manner, with retinoic acid receptor (RAR) dominating over vitamin D receptor (VDR) in the absence of agonist or with both agonists present. Both RAR and VDR reduce the DNA-bound fraction of each other in the absence of ligand, and the competing NR's agonist decreases the DNA-bound fraction of the other NR. These findings provide insights into the possible amelioration of side effects in NR-ligand-based therapies and complement the model of NR action involving competition for retinoid X receptor (RXR) and DNA sites.

Evidence of Noisy Oscillations of cAMP under Nutritional Stress Condition in Budding Yeast

Sonia Colombo, Maddalena Collini, Laura D'Alfonso, Giuseppe Chirico, Enzo Martegani

Summary: This study reveals that the Ras/cAMP/PKA pathway plays a crucial role in regulating the response to nutrients' availability and stress in budding yeast. The activity of this pathway leads to noisy oscillations of cAMP levels, which in turn affects the nuclear accumulation of the transcription factor Msn2. Using a sensor, the researchers were able to detect the changes in cAMP concentrations in single yeast cells and observed oscillations under conditions of nutritional stress caused by limiting glucose availability.

Summary: The study discusses the impact of bendable structures under continuous flow, fabricates flexible microstructures using two-photon laser polymerization, and characterizes their bending dynamics and elastic properties. The results show a correlation between the elastic constant of the microstructures and the deflection-flow dependence, suggesting potential value for the development of energy conversion platforms.
