    Description: It has been postulated that the brain operates in a self-organized critical state that brings multiple benefits, such as optimal sensitivity to input. Thus far, self-organized criticality has typically been depicted as a one-dimensional process, where one parameter is tuned to a critical value. However, the number of adjustable parameters in the brain is vast, and hence critical states can be expected to occupy a high-dimensional manifold inside a high-dimensional parameter space. Here, we show that adaptation rules inspired by homeostatic plasticity drive a neuro-inspired network to drift on a critical manifold, where the system is poised between inactivity and persistent activity. During the drift, global network parameters continue to change while the system remains at criticality.

    Description: Current questions in ecology revolve around instabilities in the dynamics on spatial networks and particularly the effect of node heterogeneity. We extend the master stability function formalism to inhomogeneous biregular networks having two types of spatial nodes. Notably, this class of systems also allows the investigation of certain types of dynamics on higher-order networks. Combined with the generalized modeling approach to study the linear stability of steady states, this is a powerful tool to numerically asses the stability of large ensembles of systems. We analyze the stability of ecological metacommunities with two distinct types of habitats analytically and numerically in order to identify several sets of conditions under which the dynamics can become stabilized by dispersal. Our analytical approach allows general insights into stabilizing and destabilizing effects in metapopulations. Specifically, we identify self-regulation and negative feedback loops between source and sink populations as stabilizing mechanisms and we show that maladaptive dispersal may be stable under certain conditions.

    Description: The Aeolian Archipelago (Southern Tyrrhenian Sea, Italy) hosts important foraging/overwintering habitats for Mediterranean loggerhead sea turtles (Caretta caretta), although nesting sites have never been documented. This study reports the data of two nesting events occurred in summer 2019 at Stromboli and Lipari islands. A hatchling success of 20.69 % (18 hatchlings from 87 eggs) was recorded at Stromboli, while a complete hatchling unsuccess characterised the Lipari nest, where 111 eggs were deposited. Data acquired during the monitoring of the nests suggest that combined factors, mainly temperature, beach morphology, and sand composition, could be the causes for the low success of these nesting events.

    Description: Mummy studies help scientists to reconstruct both the evolution and manifestation of past dis-eases as well as the lifestyles and the habits of the ancient populations. They also help to gain insights into their funerary rites, which are a refl ection of the community spiritual beliefs. Last but not least, the study of embalmed corpses reveals the evolution of the mortuary practices. After the 1840’s, new embalming methods were developed; these coupled the use of chemical solution and arterial injection thus allowing the corpses to maintain their integrity (no exter-nal lacerations) together with a life-like appearance. An extremely interesting case of modern chemical embalming is that of Rosalia Lombardo (1918-1920), a two years old girl who died in Palermo. Her cadaver is housed in the Capuchin Catacombs of the Sicilian capital. Both her cause of death and the procedure used in her embalming are still enigmatic. Her embalming has been allegedly attributed to Alfredo Salafi a, a renowned Palermitan embalmer. This paper addresses the most recent fi ndings emerged from our re-analysis of Rosalia’s case; furthermore, the cosmetic treatment of Rosalia’s mummy is compared with those of Ernesto Salafi a Maggio and Giovanni Paterniti, two individuals whose bodies were embalmed by Alfredo Salafia.
