A major challenge in effective active ageing support is to identify/design new organizational structures, approaches, and mechanisms so that on one hand older people do not feel excluded, and on the other hand they have the chance to make valued contributions to the communities where they live. Collaborative networks involving a variety of stakeholders, e.g. senior professionals, intermediary e...

In plants, perception of invading pathogens involves cell-surface immune receptor kinases. Here, we report that the Arabidopsis SITE-1 PROTEASE (S1P) cleaves endogenous RAPID ALKALINIZATION FACTOR (RALF) propeptides to inhibit plant immunity. This inhibition is mediated by the malectin-like receptor kinase FERONIA (FER), which otherwise facilitates the ligand-induced complex formation of the im...

The mid infrared spectra of the starbursts show the 9.7μm silicate absorption feature and strong mid infrared emission bands centered at 6.2, 7.7, and 11.3 μm. Illustrative models of the active galaxies are presented: As the starbursts are most likely confined to the central region of the galaxy the radiative transfer in the nucleus is solved under the assumption of spherical symmetry. The dist...

Perowskite In der Zuschrift auf S. 3952 stellen Ralf Tonner, Johanna Heine et al. Modellverbindungen mit [PbE2I16]8−-Anionen (E = Sb, Bi) vor, die präzise Ausschnitte von dotierten Perowskiten darstellen. Die Verbindungen zeigen erstaunlich kleine Bandlücken.
