Distinguishing early domesticates from their wild progenitors presents a significant obstacle for understanding human-mediated effects in the past. The origin of dogs is particularly controversial because potential early dog remains often lack corroborating evidence that can provide secure links between proposed dog remains and human activity. The Tumat Puppies, two permafrost-preserved Late Pleistocene canids, have been hypothesized to have been littermates and early domesticates due to a physical association with putatively butchered mammoth bones. Through a combination of osteometry, stable isotope analysis, plant macrofossil analysis, and genomic and metagenomic analyses, this study exploits the unique properties of the naturally mummified Tumat Puppies to examine their familial relationship and to determine whether dietary information links them to human activities. The multifaceted analysis reveals that the 14,965–14,046 cal yr BP Tumat Puppies were littermates who inhabited a dry and relatively mild environment with heterogeneous vegetation and consumed a diverse diet, including woolly rhinoceros in their final days. However, because there is no evidence of mammoth consumption, these data do not establish a link between the canids and ancient humans.

Do populist governments bend their economic policies to the preferences of bondholders? Populist governments should be a “least likely” case for the market discipline hypothesis. Populist parties typically run on platforms that scapegoat wealthy elites as “enemies of the people” and hence should be more resistant to changing policy positions in the face of market pressure, given their reluctance to alienate their base. Employing most-different case studies of the Five Star Movement/Lega coalition in Italy and Viktor Orbán’s government in Hungary, we find that populists do bend to market pressure but that this “disciplining effect” does not stem primarily from foreign investors. Rather, it was the inaction of domestic investors in bond auctions that caused these governments to reverse course on headline economic policies. Because domestic investors served as both governments’ “buyers of last resort,” they needed to maintain their favor amidst foreign capital flight.

Housing scarcity is a widespread social and economic problem. Prior studies have attributed this scarcity to local control over land use, which has been seen as making policy makers more responsive to small electorates. Challenging this argument, we suggest that smaller jurisdictions have stronger incentives and greater capacity to raise tax revenue by building housing. Therefore, expanding the electorate that policy makers are responsive to could lead to a more restrictive housing policy. To explore this question empirically, we study a reform that consolidated some Danish municipalities, increasing the size of their jurisdiction. Using a difference-in-differences design, we find that consolidated municipalities issue fewer permits and complete less housing than smaller jurisdictions. Our study thus shows that politicians permitted more housing when they were accountable to a smaller electorate. This upends conventional wisdom and suggests that local control need not be at odds with more liberal land use policy.

Portable medical equipment (PME) is inconsistently cleaned and disinfected, resulting in contamination that increases the risk of healthcare-associated infections. A virtual reality PME cleaning and disinfection training module was designed and tested at multiple healthcare facilities. Barriers identified during an initial phase led to improvements in the second phase.

Studying deep-water shark species presents inherent challenges stemming from the difficulty in accessing their habitats, coupled with factors such as low population densities, intricate behaviours, and complex biological attributes. The integration of citizen scientists, particularly fishers, offers a valuable avenue to make use of their life-long insights and expertise, thus facilitating the acquisition of crucial data that can effectively enhance the realm of shark research. Our collaborative engagement with fishers since 2017 has yielded an extensive documentation concerning elasmobranchs in the Caribbean region of Puerto Rico providing a unique opportunity to formally record species hitherto unreported. This is exemplified by the first documentation of the smalltooth sandtiger shark (Odontaspis ferox (Risso, 1810)). Despite its broad geographic range and widespread distribution in temperate and tropical marine environments, there is a lack of comprehensive scientific understanding and limited available knowledge regarding this species. A noteworthy finding on December 30, 2020, near Rincón (northwest coast) in Puerto Rico, disclosed a large shark that an experienced fisher had captured as an unidentified by-catch at a depth of 325 m. Through an interdisciplinary approach using molecular (355 bp, Cytochrome Oxidase Subunit 1) and morphological techniques, we successfully confirmed the identity of the specimen as a female smalltooth sandtiger shark. Given the limited information available (e.g., diversity, abundance, behaviour, reproduction, distribution) on shark species in the coastal and deep waters of Puerto Rico, this report provides valuable new data that can significantly contribute to the conservation efforts to protect these enigmatic yet ecologically vital predators.

Early Miocene land mammals from eastern North America are exceedingly rare. Over the past several decades a small, but significant, vertebrate fauna has been recovered by paleontologists and citizen scientists from the Belgrade Formation at the Martin Marietta Belgrade Quarry in eastern North Carolina. This assemblage has 12 land mammal taxa, including beaver (Castoridae), stem lagomorph, carnivorans (Mustelidae, Ailuridae), horses (Equidae), rhinoceros (Rhinocerotidae), tapir (Tapiridae), peccary (Tayassuidae), anthracothere (Anthracotheriidae), entelodont (Entelodontidae), and protoceratid (Protoceratidae). Taken together, the biochronology of this Maysville Local Fauna indicates a late Arikareean (Ar3/Ar4) to early Hemingfordian (He1) North American Land Mammal Age (NALMA). This interval, which includes the Runningwater Chronofauna, documents numerous important Holarctic immigrants, including Amphictis, Craterogale, and cf. Menoceras found at this locality. Strontium isotope stratigraphy (SIS) of shark teeth collected in situ from the Belgrade Formation yield an age of 21.4 ± 0.13 Ma, which validates the age of interbedded land mammals within this unit. It also is consistent with the late Arikareean (Ar3/Ar4) biochronology and Aquitanian Neogene marine stage. New SIS analyses of oysters (Striostrea gigantissima) and clams (Chione) from this mine, previously assigned to late Oligocene or Late Miocene, are significantly older (28.0 ± 0.22 Ma and 27.6 ± 0.26 Ma, respectively) than the land mammals. Depending upon stratigraphic interpretations, these may confirm an older marine facies within the Belgrade Formation. This locality is important because of its marine and terrestrial tie-ins that facilitate intercalibration of both NALMAs and Cenozoic marine stages.

In the first part of the paper, we prove a mirror symmetry isomorphism between integral tropical homology groups of a pair of mirror tropical Calabi-Yau hypersurfaces. We then apply this isomorphism to prove that a primitive patchworking of a central triangulation of a reflexive polytope gives a connected real Calabi-Yau hypersurface if and only if the corresponding divisor class on the mirror is not zero.

Marseille is a city that has long been sensationalistically associated in the public imagination with crime and drug dealing. This article begins by tracing the history of drug dealing and gang violence in the city, from its 19th century origins to the rise of what has been called the “French Connection” in the 1960s and 1970s, when Marseille played a central role in the global heroin trade. The city’s criminality subsequently became more local in scope in the 1980s and 1990s, and the second part of the article draws on recent research carried out in the Marseille cité of Félix-Pyat, a poor neighbourhood widely associated with gang violence and drug dealing, to explore the consequences of the changing nature of crime in the city for process of “criminal governance”. When considered historically and in relation to our previous research on gangs in Nicaragua and South Africa, we suggest that it might be appropriate to talk about there being “varieties” of criminal governance that come together as “assemblages” than can be constituted in fundamentally different ways.

The 2024 presidential election was historic in many ways, but one trend did not buck the norm: the gender gap. Indeed, despite Kamala Harris becoming the first Black and South Asian woman to win a majority party’s nomination, the recent overturning of Roe v. Wade, and clear attempts by the Harris campaign to win over white Republican women voters, “gender differences in vote choice in the 2024 elections were remarkably similar to recent presidential elections” (CAWP 2024). This essay highlights the long-term ideological and demographic shifts among party constituencies that can help to explain why Republican women cast their vote for Donald Trump, even in a uniquely gendered political landscape.

Databases of baby names are commonly available and have often been used to assess people’s reactions to events such as wars or diplomatic crises. Changes in the frequency of several candidate names are usually investigated around the event of interest. This approach misses key information simply because not all information-carrying names have been thought about. More fundamentally, whether exogenous shocks can significantly alter population-level naming preferences remains elusive. We present here a method to systematically study variations in name popularity during an event of interest and quantify its “total” effect on naming patterns. Using a nationwide database of first name frequencies since 1900, we apply the method to France during the First World War. We find several dozen first names the popularity of which was modified by the War. While we find macro-level traces of individual-level phenomena, in particular increased naming for kin, specific first names also provide key insights into the civilian population’s changing attitude – e.g., widespread pessimism in 1917. Using an individual-level database of ∼9.5 million individuals enables us to track such changes in morale month after month. The aggregate effect of the war on naming patterns was maximal and large early in the conflict, then gradually declined: the return of naming preferences to their prewar state illustrates and quantifies how the “banality of war” installed.

The association between low household income and adolescent mental health causes continuing concern. We examined the relation between household income and adolescent internalizing and externalizing problems, and explored individual, parental, and neighborhood characteristics. The sample included 872 Dutch adolescents (Mage = 14.93 years) oversampled on risk of psychopathology. Low income was defined as parent-reported net monthly household income below the 20th percentile (<€2000). Internalizing and externalizing problems were examined using the Youth Self-Report and Child Behavior Checklist. Covariates included sex, age, ethnic background, IQ, perceived social support, adverse life events, physical health, parental psychopathology, parental IQ, parent-child interaction, neighborhood unemployment rate, and neighborhood violence. Low household income was associated with more internalizing and externalizing problems. These associations were explained by more physical health concerns, increased parental psychopathology, more parent-child interaction problems, more adverse life events, lower perceived social support, and lower adolescent IQ. For all, except for mother-child interaction, a mediating role was suggested. This indicates a complex interplay between household income, individual, social, and parental factors affecting adolescent mental health. This study accentuates the necessity for a comprehensive, multi-faceted approach to address the negative effects of poverty on adolescent mental health, targeting these influences for preventive measures.

The global nutrition community faces an urgent imperative to address inequities in food security while promoting inclusive approaches to nutrition science and practice. The Nutrition Society of Australia’s 2024 Annual Scientific Meeting on ‘Food for All: Promoting Equity, Diversity, and Inclusion in Nutrition’ addressed this critical challenge through a 4-day programme of cutting-edge, multi-disciplinary research. The conference brought timely focus to key issues, including food access, cultural food practices, nutrition service accessibility, and inclusive research and education approaches. The conference featured public presentations, workshops, oral and poster sessions, symposia, and early career researcher sessions, and emphasised incorporating diverse perspectives while highlighting collaborative approaches to promoting equitable food systems. Coordinated efforts among researchers, healthcare providers, community organisations, industry partners and policymakers remain essential to advance inclusive nutrition practices and ensure equitable access to nutritious food for all populations.
