Renaissance of the Trinitarian: Erwin Schadel's Integral Perspective
Modern Theology, EarlyView.Abstract Erwin Schadel (1946–2016), a central yet little‐known figure of the so‐called Bamberg School, developed a distinctive triadic ontology that deserves attention within the contemporary renaissance of Trinitarian thought. Drawing on Augustinian and Comenian sources, Schadel articulates a relational grammar of being through the categories of in ...

Circular RNAs in Lotus japonicus Responses to Nutrient Supply and Mesorhizobium Symbiosis
Plant, Cell &Environment, EarlyView.ABSTRACT Symbiotic interactions between legumes and rhizobia enable nitrogen fixation under low nutrient conditions. The establishment and function of symbiotic interactions require coordinated changes in gene expression in both the host and the microbe. Circular RNAs (circRNAs) are endogenous gene‐specific molecules that can regulate transcription and

Necessity of electrically conductive pili for methanogenesis with magnetite stimulation
PeerJ, 2018 Background Magnetite-mediated direct interspecies electron transfer (DIET) between Geobacter and Methanosarcina species is increasingly being invoked to explain magnetite stimulation of methane production in anaerobic soils and sediments.

Photophobotaxis of single‐celled and filamentous cyanobacteria
Photochemistry and Photobiology, EarlyView.LED illumination from below induces central accumulation of cyanobacterial species. Abstract Phototaxis refers to an organism's movement toward a light source, while photophobotaxis involves movement into illuminated regions. Although phototaxis in cyanobacteria has been widely studied, photophobotaxis has been investigated in only a few species.
