1. Homelessness and water insecurity in the Global North: Trapped in the dwelling paradox

   https://doi.org/10.1002/wat2.1651

   Abstract In this article, we introduce the “dwelling paradox” to explore how the state actively produces water insecurity for people experiencing homelessness in the Global North. We explain that the dwelling paradox is (1) produced by a modernist ideology of public service delivery that privileges water provision through private infrastructural connections in the home; (2) is reproduced by the welfare‐warfare state, which has increasingly weaponized public water facilities and criminalized body functions in public space; and (3) is actively contested by some houseless communities, who challenge hegemonic ideals of the “home”—and its water infrastructure—as a private, atomized space. In advancing a relational and spatial understanding of water insecurity, we use the dwelling paradox to illustrate how unhoused people are caught in a space of institutional entrapment that is forged by state power and amplified by anti‐homeless legislation. Such spaces of entrapment make it extremely difficult for unhoused people to achieve a safe, healthy, and thriving life—the basis of the human rights to water and sanitation.

2. The Role of Swelling in the Regulation of OPA1-Mediated Mitochondrial Function in the Heart In Vitro

   Chapa-Dubocq, Xavier R.; Rodríguez-Graciani, Keishla M.; García-Báez, Jorge; Vadovsky, Alyssa; Bazil, Jason N.; Javadov, Sabzali (August 2023, Cells)

   Optic atrophy-1 (OPA1) plays a crucial role in the regulation of mitochondria fusion and participates in maintaining the structural integrity of mitochondrial cristae. Here we elucidate the role of OPA1 cleavage induced by calcium swelling in the presence of Myls22 (an OPA1 GTPase activity inhibitor) and TPEN (an OMA1 inhibitor). The rate of ADP-stimulated respiration was found diminished by both inhibitors, and they did not prevent Ca2+-induced mitochondrial respiratory dysfunction, membrane depolarization, or swelling. L-OPA1 cleavage was stimulated at state 3 respiration; therefore, our data suggest that L-OPA1 cleavage produces S-OPA1 to maintain mitochondrial bioenergetics in response to stress.

3. The “Notch” in Unstable Layers and the Stability Minimum in the Tropics

   https://doi.org/10.1175/JCLI-D-24-0135.1  

   Geller, Marvin_A; Wang, Ling (December 2024, Journal of Climate)

   Abstract In a previous paper, we identified a “notch” in unstable layers at Koror (7.3°N, 134.5°E), where there was a relative deficiency in thin unstable layers and a corresponding relative excess in thicker layers, at altitudes centered at 12 km. We hypothesized that this feature was associated with the previously identified stability minimum in the tropics at that same altitude. In this paper, we extend our studies of this notch and its association with the tropical stability minimum by examining other stations in the deep tropics and also some stations at higher latitudes within the tropics. We find that this notch feature is found at all the other radiosonde stations in the deep tropics that we examined. We also find that the annual variations in unstable layer occurrences at stations at higher latitudes within the tropics show variations consistent with our hypothesis that this notch is associated with the region of minimum stability in the tropics at altitudes centered around 12 km, in that the annual variation in this notch feature is consistent with the annual variation of minimum stability in this region. Two factors contribute to the notch feature. One is that the data quality control procedure of the analysis rejects many thin layers due to the small trend-to-noise ratio in the region of minimum stability. The other is that the cloud-top outflow, which was previously identified with the stability minimum, advects thicker unstable layers throughout the deep tropics at the altitudes of the notch. Significance StatementPrevious papers have separately identified a stability minimum in the tropics and a “notch” feature in the thicknesses of unstable atmospheric layers where there are less thin unstable layers and a corresponding excess of thicker unstable layers, both at altitudes around 12 km. We previously hypothesized that these two features were associated with one another. In this paper, we examine this notch feature and the minimum in atmospheric stability at both deep tropical radiosonde stations and stations located at higher latitudes in the tropics, and we find that the annual variation of this notch feature is consistent with the latitudinal migration of the latitudes of the stability minimum. Turbulence associated with this notch feature might be significant for aircraft operations.

4. The coyote in the cloud

   https://doi.org/10.1177/25148486241229011  

   Niesner, Chase A; Kelty, Christopher; Robins, Spencer (June 2024, Environment and Planning E: Nature and Space)

   Coyotes (Canis latrans) exist throughout North America and increasingly thrive in dense urban spaces; they also cause controversies when they eat small pets or seem to pose a threat. Based on fieldwork in Los Angeles, and an archive of over 400 conversations collected from the online application Nextdoor (2015–2019), we theorize the emergence of what we call the cloud coyote. Cloud coyotes are not representations but lively actors in coyote politics animated by discussion, debate, and a settler logic of property relations in places like Los Angeles. They do this by performing a threat and justifying a response that includes various attempts at extermination, containment, and assimilation, all of which—even supposedly humane alternatives—further sediment forms of settler colonialism in urban Los Angeles. We diagnose this process, show how it works, and argue that anticolonial practices—in both Los Angeles and its cloudy territories like Nextdoor—are needed to escape from perpetuating its violence.

5. The role of vision in the acquisition of words: Vocabulary development in blind toddlers

   https://doi.org/10.1111/desc.13475  

   Campbell, Erin; Casillas, Robyn; Bergelson, Elika (January 2024, Developmental Science)

   Abstract What is vision's role in driving early word production? To answer this, we assessed parent‐report vocabulary questionnaires administered to congenitally blind children (N = 40, Mean age = 24 months [R: 7–57 months]) and compared the size and contents of their productive vocabulary to those of a large normative sample of sighted children (N = 6574). We found that on average, blind children showed a roughly half‐year vocabulary delay relative to sighted children, amid considerable variability. However, the content of blind and sighted children's vocabulary was statistically indistinguishable in word length, part of speech, semantic category, concreteness, interactiveness, and perceptual modality. At a finer‐grained level, we also found that words’ perceptual properties intersect with children's perceptual abilities. Our findings suggest that while an absence of visual input may initially make vocabulary development more difficult, the content of the early productive vocabulary is largely resilient to differences in perceptual access. Research HighlightsInfants and toddlers born blind (with no other diagnoses) show a 7.5 month productive vocabulary delay on average, with wide variability.Across the studied age range (7–57 months), vocabulary delays widened with age.Blind and sighted children's early vocabularies contain similar distributions of word lengths, parts of speech, semantic categories, and perceptual modalities.Blind children (but not sighted children) were more likely to say visual words which could also be experienced through other senses.
