Sensory fusion in Physarum polycephalum and implementing multi-sensory functional computation

Surface electrical potential and observational growth recordings were made of a protoplasmic tube of the slime mould Physarum polycephalum in response to a multitude of stimuli with regards to sensory fusion or multisensory integration. Each stimulus was tested alone and in combination in order to evaluate for the first time the effect that multiple stimuli have on the frequency of streaming oscillation. White light caused a decrease in frequency whilst increasing the temperature and applying a food source in the form of oat flakes both increased the frequency. Simultaneously stimulating P. polycephalum with light and oat flake produced no net change in frequency, while combined light and heat stimuli showed an increase in frequency smaller than that observed for heat alone. When the two positive stimuli, oat flakes and heat, were combined, there was a net increase in frequency similar to the cumulative increases caused by the individual stimuli. Boolean logic gates were derived from the measured frequency change. © 2014

Being skeptical? Exploring far-right climate change communication in Germany

This article explores climate-change communication by the German far right – spanning a continuum which ranges from anti-liberal democracy radical-right populists, to the extreme right and to antidemocratic neo-Nazis – and asks: how do these actors articulate the phenomenon of climate change? In responding to this question, we conduct a discourse network analysis which identifies relations between actors, objects, phenomena and processes, and point out differences/similarities across a continuum of exemplary far-right sources. The investigated actors put forward a rather skeptical climate change narrative, even though differences exist as the significance attached to the Volk and its sovereignty, rooted in far-right ideology, sometimes overrides, and sometimes is in harmony with, their ideological-driven affinity with nature protection. We thus contribute to the growing body of knowledge on climate-change communication and, more specifically, on the link between ideology and climate-change skepticism
