      Universal formal education is a major global development goal. Yet hunter-gatherer communities have extremely low participation rates in formal schooling, even in comparison with other marginalized groups. Here, we review the existing literature to identify common challenges faced by hunter-gatherer children in formal education systems in the Global South. We find that hunter-gatherer children are ...
    • The nasal cavity of the bearded seal: An effective and robust organ for retaining body heat and water 

      Cheon, Hyejeong Lee; Kizilova, Nataliya; Flekkøy, Eirik Grude; Mason, Matthew J.; Folkow, Lars; Kjelstrup, Signe (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09-10)
      We report the effects of varying physiological and other properties on the heat and water exchange in the maxilloturbinate structure (MT) of the bearded seal (Erignathus barbatus or Eb) in realistic environments, using a computational fluid dynamics (CFD) model. We find that the water retention in percent is very high (about 90 %) and relatively unaffected by either cold (−30 ◦C) or warm (10 ◦C) ...
    • Kinetically-Controlled Ni-Catalyzed Direct Carboxylation of Unactivated Secondary Alkyl Bromides without Chain Walking 

      Davies, Jacob; Lyonnet, Julien R.; Carvalho, Bjørn; Sahoo, Basudev; Day, Craig S.; Juliá-Hernández, Francisco; Duan, Yaya; Álvaro Velasco-Rubio, None; Obst, Marc; Norrby, Per-Ola; Hopmann, Kathrin Helen; Martin, Ruben (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-09)
      Herein, we report the direct carboxylation of unactivated secondary alkyl bromides enabled by the merger of photoredox and nickel catalysis, a previously inaccessible endeavor in the carboxylation arena. Site-selectivity is dictated by a kinetically controlled insertion of CO<sub>2</sub> at the initial C(sp<sup>3</sup> )−Br site by the rapid formation of Ni(I)−alkyl species, thus avoiding undesired ...

    • On the impact of net-zero forcing Q-flux change 

      Eiselt, Kai-Uwe; Graversen, Rune Grand (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-22)
      Numerical climate model simulations suggest that global warming is enhanced or hampered by the spatial pattern of the warming itself. This phenomenon is known as the “pattern effect” and has in recent years become the most promising explanation for the change over time of climate sensitivity in climate models. Under historical global warming, different patterns of surface-temperature change have ...
    • Tumor versus Tumor Cell Targeting in Metal-Based Nanoparticles for Cancer Theranostics 

      Urbano-Gámez, Jesús David; Guzzi, Cinzia; Bernal, Manuel; Solivera, Juan; Martinez, Inigo Zubiavrre; Caro, Carlos; García-Martín, María Luisa (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-10)
      The application of metal-based nanoparticles (mNPs) in cancer therapy and diagnostics (theranostics) has been a hot research topic since the early days of nanotechnology, becoming even more relevant in recent years. However, the clinical translation of this technology has been notably poor, with one of the main reasons being a lack of understanding of the disease and conceptual errors in the design ...
    • Gene Expression and Phenotypic Assessment of Egg Quality across Developmental Stages of Atlantic Cod throughout the Spawning Season 

      Fernandez Miguez, Maria; Presa, Pablo; Puvanendran, Velmurugu; Tveiten, Helge; Hansen, Øyvind J; Pérez, Montse (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-08)
      Egg quality in fishes is commonly determined by fertilisation success and cleavage patterns as a phenotypic outcome of underlying regulatory mechanisms. Although these phenotypic estimators of egg quality are useful in farming conditions, these “good quality” egg batches do not always translate to good larval growth and survival. The identification of genes involved in embryonic development may help ...
    • Address Social Injustices in Taxonomy: Implement Extended Revisions of Names with Ethical Issues and Persistent Identifiers for Tracing Name Changes 

      Gelete, Desalegn Chala; Endresen, Dag; Demissew, Sebsebe; Slaughter, Laura Ann; Johnsen, Einar Broch; Stenseth, Nils Christian (Journal article; Tidsskriftartikkel, 2024-07-22)
      The binomial nomenclature system, introduced by Carl Linnaeus in the 18th century, has been fundamental for scientific communication and data management. Despite its utility, some scientific names reflect historical biases and ethical issues, including colonial legacies, racism, sexism, and derogatory terms. Recent debates highlight the need to address these injustices, with arguments both for and ...
