The Anthropocene concept arose within the Earth System science community, albeit explicitly as a geological time term. Its current analysis by the stratigraphical community, as a potential formal addition to the Geological Time Scale, necessitates comparison of the methodologies and patterns of enquiry of these two communities. One means of comparison is to consider some of the most widely used results of the ESS, the ‘planetary boundaries’ concept of Rockström and colleagues, and the ‘Great Acceleration’ graphs of Steffen and colleagues, (...) in terms of their stratigraphical expression. This expression varies from virtually non-existent to pronounced and many-faceted, while in some cases stratigraphical proxies may help constrain anthropogenic process. The Anthropocene concepts of the ESS and stratigraphy emerge as complementary, and effective stratigraphic definition should facilitate wider transdisciplinary communication. (shrink)

We discuss the cities of the future, and how they might co-habit with the biosphere in a more mutually beneficial way. Mutualistic cities would blend with their local ecology, co-existing with the immediately available resources of water, life, energy and materials, and enhancing the biosphere so that many species can thrive, including people. Such cities can make a significant contribution to stabilizing the Earth System by sustaining and nurturing life in tune with the evolving local ecology through cyclic economies and (...) values prioritizing mutually supportive communities over economic growth. The term “mutualism” comes from biology, referring to inter-species relationships that are beneficial. Mutualistic cities would benefit human and non-human inhabitants by recycling materials, clean air, and water, and providing habitats for many species. (shrink)

ObjectiveBulimia nervosa and binge eating disorder are eating disorders characterized by recurrent binge eating episodes. Overlap exists between ED diagnostic groups, with BE episodes presenting one clinical feature that occurs transdiagnostically. Neuroimaging of the responses of those with BN and BED to disorder-specific stimuli, such as food, is not extensively investigated. Furthermore, to our knowledge, there have been no previous published studies examining the neural response of individuals currently experiencing binge eating, to low energy foods. Our objective was to examine (...) the neural responses to both low energy and high energy food images in three emotive categories in BN and BED participants.MethodsNineteen females with BN or BED, comprising the binge eating group, and 19 age-matched healthy control ’s completed thorough clinical assessment prior to functional MRI. Neural response to low energy and high energy foods and non-food images was compared between groups using whole-brain exploratory analyses, from which six regions of interest were then selected: frontal, occipital, temporal, and parietal lobes; insula and cingulate.ResultsIn response to low energy food images, the BEG demonstrated differential neural responses to all three low energy foods categories compared to HCs. Correlational analyses found a significant association between frequency of binge episodes and diminished temporal lobe and greater occipital lobe response. In response to high energy food images, compared to HC’s, the BEG demonstrated significantly decreased neural activity in response to all high energy food images. The HC’s had significantly greater neural activity in the limbic system, occipital lobe, temporal lobe, frontal lobe, and limbic system in response to high energy food images.ConclusionResults in the low energy food condition indicate that binge frequency may be related to increased aberrant neural responding. Furthermore, differences were found between groups in all ROI’s except the insula. The neural response seen in the BEG to disgust food images may indicate disengagement with this particular stimuli. In the high energy food condition, results demonstrate that neural activity in BN and BED patients may decrease in response to high energy foods, suggesting disengagement with foods that may be more consistent with those consumed during a binge eating episode.

In this paper we argue that individuals in modern societies can share a general appreciation of the contingency of moral and political engagement without endangering these purposeful attachments. Depending upon the acceptance of various cognitive conventions, social practices and institutions cannot be sustained by appeals to advantage alone, but these conventions do not demand ontological commitment. Transparent fictions rather than ideological illusions can suffice to sustain valued forms of life. In contrast to Rorty's ironic society in which "only the intellectuals (...) would be ironists", we suggest the benign disillusionment can characterize the public generally. (shrink)

Notions of the cosmos are deep-rooted in human consciousness. They are expressed in our earliest monumental constructions as explanations of the world around us and in the practices of many indigenous peoples. Here we examine the physical cosmos from the perspective of life on Earth. We note a central importance for the Earth in the vastness of space, as a planetary oasis for a highly complex and long-lived biosphere, one now being fundamentally altered by humans. We refer to other notions (...) of the cosmos that may enable us to navigate a better path for life in the Anthropocene. (shrink)

The biosphere coevolves with the atmosphere, hydrosphere and lithosphere to maintain a habitable space on Earth. Over billions of years – and despite periodic setbacks – it has evolved increasing complexity, from its microbial beginnings to the complex interactions between animals, plants, fungi and unicellular microscopic life that sustain its present state. Recently, the biosphere has been profoundly changed by humans. In part, this includes increased rates of extinction that are reminiscent of past fundamental perturbations to life. But the change (...) is even more profound, resulting from a combination of marked translocations of species beyond their indigenous ranges, overt concentration of biomass in humans and their farm animals, reconfiguration of landscape habitats and over-utilisation of ocean life, excessive appropriation of energy from the biosphere (including its fossilised component), and increasing interconnectivity between technology and life.

The Anthropocene Working Group of the Subcommission on Quaternary Stratigraphy, of the International Commission on Stratigraphy, has been active since 2009. Its primary role is to consider the Anthropocene as a potential formal addition to the Geological Time Scale. Unusual in composition because many members work in disciplines other than stratigraphic geology —the Anthropocene incorporates geological, historical, and instrumental records— it initially needed to establish whether the Anthropocene could be the basis of a valid chronostratigraphic unit. That task achieved, work (...) then focused on gathering evidence from 12 sections in different geological settings around the world, to establish which of these might be proposed as a Global boundary Stratotype Section and Point (GSSP, or ‘golden spike’) to define the Anthropocene formally. The Group aims to submit a formal proposal on this in 2023. (shrink)
