Banlieue Nord: A Brief Contribution to How We Inhabit the North and How the North Inhabits Us

Beyond its many simplified representations such as cold, hostile, uninhabited, or unknown, the north reveals itself as a complex and multiple space of interwoven geographical, cultural, social, and conceptual dimensions. Influenced by world views, the power of maps and myths as well as the very relation to the landscape itself as one of extraction or attraction, humans subjectively apprehend these multiple norths. By dwelling in the northern lands through experience or imagination, ‘southerners’ and ‘northerners’ alike do not simply inhabit the north; they are in turn inhabited by it. Situated at the ‘gates of the north’ in subarctic Canada, the mono-industrial company town Fermont fits its town centre entirely under a single roof. Planned and commissioned in the 1970s by a mining company, the town’s Utopian purpose was to ‘make a society’ in an inhospitable climate, while serving the exploitation of the mine. Fermont’s case serves here as a laboratory to understand the complexities of the north in more general terms. At the crossroads of image-based practices and the humanities, this contribution engages with the question of how humans inhabit the north and how they are inhabited by it

Opening the Industry Playbook: Myths and Truths in the Debate over BPA Regulation

For the last two decades, scientists have amassed evidence that bisphenol A (BPA) poses a threat to human health. Although scientists have targeted BPA as a public health concern, plastics industry lobbyists have attempted to thwart the efforts of federal, state, and local authorities to reduce exposure to BPA. This paper reviews the major arguments advanced by the plastics industry and debunks them as “myths” that public health officials must reject. The five topics covered include: the myth of scientific consensus on safety; the myth that only studies complying with “Good Laboratory Practices” guidelines are adequate for making regulatory decisions; myths about the science of BPA exposure and metabolism; economic myths related to restrictions on BPA’s use; and the myth that state-based regulation creates an unmanageable “patchwork” of rules. After critiquing the facts and policy implications of each issue, the authors conclude with suggestions regarding how federal agencies can coordinate their work to better protect the public from the risks posed by BPA and other endocrine disrupting chemicals

Specific gut microbiota features and metabolic markers in postmenopausal women with obesity

BACKGROUND: Gut microbial gene richness and specific bacterial species are associated with metabolic risk markers in humans, but the impact of host physiology and dietary habits on the link between the gut microbiota and metabolic markers remain unclear. The objective of this study was to identify gut metagenomic markers associated with estimates of insulin resistance, lipid metabolism and inflammation in obesity, and to explore whether the associations between metagenomic and metabolic markers persisted after adjustment for body fat, age and habitual dietary intake. METHODS: Faecal DNA from 53 women with obesity was analysed through quantitative metagenomic sequencing and analysis, and a systematic search was performed for bacterial genes associated with estimates of insulin resistance, inflammation and lipid metabolism. Subsequently, the correlations between metagenomic species and metabolic markers were tested by linear regression models, with and without covariate adjustment. RESULTS: One hundred and fourteen metagenomic species correlated with metabolic markers (P<0.001) including Akkermansia muciniphila, Bilophila wadsworthia, Bifidobacterium longum and Faecalibacterium prausnitzii, but also species not previously associated with metabolic markers including Bacteroides faecis and Dorea longicatena. The majority of the identified correlations between bacterial species and metabolic markers persisted after adjustment for differences in body fat, age and dietary macronutrient composition; however, the negative correlation with insulin resistance observed for B. longum and F. prausnitzii appeared to be modified by the intake of dietary fibre and fat, respectively. CONCLUSIONS: This study shows that several gut bacterial species are linked to metabolic risk markers in obesity, also after adjustment for potential confounders, such as long-term diet composition. The study supports the use of gut metagenomic markers for metabolic disease prediction and warrants further investigation of causality

Acceptance of near-natural greenspace management relates to ecological and socio-cultural assigned values among European urbanites

Grasslands are widespread elements of urban greenspace providing recreational, psychological and aesthetic benefits to city residents. Two urban grassland types of contrasting management dominate urban greenspaces: frequently mown, species-poor short-cut lawns and less intensively managed, near-natural tall-grass meadows. The higher conservation value of tall-grass meadows makes management interventions such as converting short-cut lawns into tall-grass meadows a promising tool for urban biodiversity conservation. The societal success of such interventions, however, depends on identifying the values urban residents assign to different types of urban grasslands, and how these values translate to attitudes towards greenspace management. Using 2027 questionnaires across 19 European cities, we identify the assigned values that correlate with people's personal greenspace use and their preferences for different types of urban grasslands to determine how these values relate to the agreement with a scenario of converting 50 of their cities� short-cut lawns into tall-grass meadows. We found that most people assigned nature-related values, such as wildness, to tall-grass meadows and utility-related values, such as recreation, to short-cut lawns. Positive value associations of wildness and species richness with tall-grass meadows, and social and nature-related greenspace activities, positively correlated with agreeing to convert short-cut lawns into tall-grass meadows. Conversely, disapproval of lawn conversion correlated with positive value associations of cleanliness and recreation potential with short-cut lawns. Here, people using greenspaces for nature-related activities were outstandingly positive about lawn conversion. The results show that the plurality of values assigned to different types of urban grasslands should be considered in urban greenspace planning. For example, tall-grass meadows could be managed to also accommodate the values associated with short-cut lawns, such as tidiness and recreation potential, to support their societal acceptance

Joint Observation of the Galactic Center with MAGIC and CTA-LST-1

MAGIC is a system of two Imaging Atmospheric Cherenkov Telescopes (IACTs), designed to detect very-high-energy gamma rays, and is operating in stereoscopic mode since 2009 at the Observatorio del Roque de Los Muchachos in La Palma, Spain. In 2018, the prototype IACT of the Large-Sized Telescope (LST-1) for the Cherenkov Telescope Array, a next-generation ground-based gamma-ray observatory, was inaugurated at the same site, at a distance of approximately 100 meters from the MAGIC telescopes. Using joint observations between MAGIC and LST-1, we developed a dedicated analysis pipeline and established the threefold telescope system via software, achieving the highest sensitivity in the northern hemisphere. Based on this enhanced performance, MAGIC and LST-1 have been jointly and regularly observing the Galactic Center, a region of paramount importance and complexity for IACTs. In particular, the gamma-ray emission from the dynamical center of the Milky Way is under debate. Although previous measurements suggested that a supermassive black hole Sagittarius A* plays a primary role, its radiation mechanism remains unclear, mainly due to limited angular resolution and sensitivity. The enhanced sensitivity in our novel approach is thus expected to provide new insights into the question. We here present the current status of the data analysis for the Galactic Center joint MAGIC and LST-1 observations
