This essay engages with law and geography in urban Asia by working through the topographies and atmospheres of law and criminal justice in Japan. The places we consider are koban (police boxes) and a legal precinct. Koban stretch across the country; the exemplary legal precinct is in Kasumigaseki, Tokyo, a gateway with mist and haze. The essay develops a set of theoretical thresholds through which to address and work through the atmospheric place-making of law and criminal justice in Tokyo’s urban environments. Our approach to relations between law and geography is situated at the crossroads of jurisprudence and humanities, criminology, and urban studies. Its two key considerations are topography and atmospheres, and place-making and its energies and folds. It is argued that topographic atmospheres of law and criminal justice are jurisdictional exercises. The essay is also an experiment in atmospheric writing.

This essay explores the Danish concept of hygge, commonly glossed as “coziness,” as a structure of feeling attuned to particular qualities of light. It draws from an ethnographic study of Copenhagen Municipality’s Climate Plan to build the world’s first carbon-neutral capital. Homing in on one of the Climate Plan’s inaugural initiatives—the LED (light-emitting diode) conversion of street lighting—it tracks how ambient intensities of hygge are swept up with both changing lightscapes and changing national demographics. Via a semiotics of social difference, I examine how changing qualities of artificial light are experienced as eroding culturally configured sensory comforts, and how this erosion is grafted onto a fear of the city’s potentially diminishing “Danishness.” This semiotic process is evidenced in the lamination of racialized anxieties about “non-Western immigrants” onto discomforts derived from energy-efficient lighting technologies, and the apparent intrusion of both into habit worlds of hygge. In Copenhagen, I show how a semiotic account of atmosphere illuminates the fault lines of the Danish racial imagination.

The study explores the vertical stratification of microbial diversity and metabolic potential in Earth’s lower atmosphere. Using 16S rRNA sequencing data spanning the planetary boundary layer to the lower stratosphere, we conducted taxonomic profiling and metabolic pathways predictions. The aim was to elucidate microbial community dynamics and their ecological roles under diverse atmospheric conditions. Methods: 51 Publicly available datasets with 3584 samples were retrieved from repositories such as Sequencing Read Archive and European Nucleotide Archive, filtered for studies employing 16S rRNA sequencing. Quality control was performed using FastQC and Trimmomatic, followed by taxonomic classification with Qiime2 and the Silva132 database. Functional pathway predictions were derived using PICRUSt2, and statistical analyses included Kruskal-Wallis tests for diversity comparisons and Mann-Whitney U tests for pathway activity. Results: Microbial diversity decreased with altitude, with the Surface Layer exhibiting the highest Shannon diversity and the significantly decreased in Low Stratosphere. Taxonomic composition shifted along the elevation gradient, with Actinobacteria and Alphaproteobacteria predominant at lower altitudes. In contrast, Bacilli and Gammaproteobacteria became more dominant at higher elevations, though they maintained a notable presence at lower sites as well. Functional analysis revealed altitude-specific adaptations, including significant upregulation of CO2 fixation pathways in the Free Troposphere Transition Layer and secondary metabolite biosynthesis in the lower stratosphere. Discussion: These findings reveal distinct microbial metabolic profiles across atmospheric layers with varying conditions such as oxygen levels, UV radiation, and nutrient availability. While these differences may represent adaptive strategies, they could also reflect source environment characteristics or selective transport processes. The conserved metabolic pathways across altitude layers suggest functional resilience despite taxonomic divergence. These results have implications for astrobiology, providing analogs for microbial life in extraterrestrial environments like Mars or Europa. In summary, this study advances our understanding of aerobiomes’ ecological roles and their potential as models for life detection in extreme environments, bridging atmospheric microbiology with astrobiological exploration.

Based on present knowledge of atmospheric composition, a mechanism for the natural formation of vesicles in the lakes of Titan is proposed. It involves precipitation-induced spray droplets coated by a monolayer of amphiphiles. On interaction with the monolayer on the lake’s surface, bilayer membranes are being formed that encapsulate the liquid phase of the original droplet. The resulting vesicles develop thermodynamic stability by continuous compositional selection of various types of amphiphiles in a dynamic equilibrium, leading to an optimized vesicle stability. Different populations of stable vesicles may compete, initiating a long-term evolution process that could eventually result in primitive protocells. The existence of any type of vesicles on Titan would prove that early steps towards increasing order and complexity have taken place, which represent the necessary precondition for abiogenesis. A valid analytical approach could involve a laser device with combined light scattering analysis and surface enhanced Raman spectroscopy. It would allow for very sensitive detection of amphiphiles as well as for the observation of dispersed vesicles.

The radiocarbon (14C) specific activity was measured in vegetation and atmosphere in Ramnicu Valcea, Romania. On the sampling location operates a nuclear installation, namely “Experimental Pilot for Separation of Tritium and Deuterium” (PESTD), a semi-industrial installation designed for the detritiation of heavy water moderator of CANDU reactors and a 315 MW coal-fired thermoelectric power plant. Because one of the important releases of PESTD is gaseous radioactive effluent, the baseline of radiocarbon was a must for the environmental program. On the other hand, due to the Suess effect, a relative decrease of the radiocarbon-specific activity on a local scale is expected as a result of the dilution of the carbon isotopic mixture by fossil carbon. All the measurements were done by liquid scintillation counting and direct absorption method. It can be observed that the specific activity of 14C was similar for both types of samples investigated. The variations encountered are generally within the limit of uncertainty associated with the 14C. The average radiocarbon-specific activity recorded has the following values: 0.226 ± 0.016 Bq/gC for the vegetation and 0.228 ± 0.016 Bq/gC for the atmosphere. The results have a clear decreasing trend, but due to local influence caused by the continuous production of fossil CO2, cannot be observed 14C seasonal variations. A strong correlation between radiocarbon activity in air and vegetation was highlighted.

As some of the most intensively devoted football fans in Germany, ultras coordinate crowd atmosphere in the arena to support their respective clubs on the field while actively positioning themselves against sport’s governing bodies, whom they see as corrupted by the strategies used to transform professional football from a game into a capitalist industry. Focusing on travel and transportation as a key feature of hardcore fandom, I examine the relationship between ultras’ activities in transit to games and their congregation in public spaces (on the streets, on trains, at rest stops, in stadia), in which quotidian ambience is often hijacked and repurposed as an estranged form of public address. I focus on the dynamic ways that ultras move through space as a means of charting the stages in which fan scenes become crowds, and crowds are mobilized as a means of protesting against the alienating dynamics of modern football, the contrasting stylistics of which result in divergent outsider interpretations and reactions from the state, the German Football Association (DFB), the media, and onlookers confronted by ultras’ public transgressions. Through the fan scene’s ability to coordinate movement and heighten bodily capacity, varied expressions of antisocial behavior become a means of harnessing fans’ own disaffection in a way that reclaims public space as it conjures a heightened emotive environment.

The first half of this short paper provides a brief introductory overview of methods to aid astronomical site testing, characterization and selection. In the second half, we describe how some of these methodologies have been applied in the search for an optical astronomical site in Kenya over the past decade.

Life as we know it requires the presence of liquid water and the availability of nutrients, which are mainly based on the elements C, H, N, O, P and S (CHNOPS) and trace metal micronutrients. We aim to understand the presence of these nutrients within atmospheres that show the presence of water cloud condensates, potentially allowing the existence of aerial biospheres. In this paper, we introduce a framework of nutrient availability levels based on the presence of water condensates and the chemical state of the CHNOPS elements. These nutrient availability levels are applied to a set of atmospheric models based on different planetary surface compositions resulting in a range of atmospheric compositions. The atmospheric model is a bottom-to-top equilibrium chemistry atmospheric model which includes the atmosphere–crust interaction and the element depletion due to the formation of clouds. While the reduced forms of CNS are present at the water cloud base for most atmospheric compositions, P and metals are lacking. This indicates the potential bio-availability of CNS, while P and metals are limiting factors for aerial biospheres.
