March 2019
Article Synopsis
- The "Promoting Responsible Research and Innovation" (RRI) initiative, part of the EU Horizon 2020 program, aligns research with societal values through public engagement, open access, and ethics, involving 6 European and 6 international institutions.
- The STARBIOS2 project aims to foster structural change in RRI at participating institutions by implementing action plans and creating guidelines for biosciences research.
- The project is structured around 6 core and 5 supporting work packages, focusing on institutional changes, technical assistance, and monitoring, and will run for four years with funding from Horizon 2020.
Article Synopsis
- Iron oxide nanoparticles (IONP) are being studied to see if they can be safely used in MRI scans and help clean up the environment.
- Researchers created special IONP particles and tested them to see how they affect living things like cells and tiny water fleas.
- Results showed that at low concentrations, IONP didn’t harm cells or the water fleas much, and they might even help reduce the use of more toxic materials in the environment.
The nucleotide sequence of the rpoN gene, formerly designated hno, and flanking DNA regions of the aerobic hydrogen bacterium Alcaligenes eutrophus has been determined; rpoN codes for the RNA polymerase sigma factor sigma 54 involved in nitrogen regulation and diverse physiological functions of gram-negative bacteria. In A. eutrophus hydrogen metabolism is under control of rpoN.

They are deficient in several diverse metabolic activities, including hydrogen oxidation, nitrate and urea assimilation, denitrification, and various substrate transport systems. Phenotypically similar mutants were identified among hydrogenase-deficient strains of Pseudomonas facilis.
View Article and Find Full Text PDFAerobic facultatively autotrophic hydrogen bacteria are distinguished on the basis of their hydrogen-oxidizing enzyme system (Hox). The major group, represented by Paracoccus denitrificans and Pseudomonas facilis, contains a membrane-bound, electron transport-coupled protein. Species of Nocardia are characterized by the possession of a cytoplasmic NAD-dependent hydrogenase.
