Globular clusters (GCs) are among the oldest and densest stellar systems in the Universe, yet how they form remains a mystery1. Here we present a suite of cosmological simulations in which both dark-matter-free GCs and dark-matter-rich dwarf galaxies naturally emerge in the Standard Cosmology. We show that these objects inhabit distinct locations in the size–luminosity plane and that they have sim
Only in primates is permanent male-female association the most widespread social structure of all. The continuous presence of resident males in the social group can have significant impacts on female fitness, both in forms of costs and benefits. In this study I investigate particular short-term benefits and costs of resident males to females in a population of ursi
Over the past fifteen years, Rwanda has made significant progress in formalizing mining rights and the production processes of 3Ts minerals in its artisanal and small-scale mining (ASM) sector. However, labour relations remain largely unregulated. This study analyses ASM activities through the production process observations, document reviews, and interviews with key informants involved in the sec
Background: Actinomycetes of the genus Streptomyces are renowned for their highly developed and diverse specialized metaboliс pathways, and there is an extensive body of data on their specific and pleiotropic levels of regulation. Much less is known about routes leading to essential metabolites in this genus. In this work, we focused on elucidating the function of the highly conserved across Strep
We theoretically investigate the properties of ultracold dipolar atoms in radially coupled, concentric annular traps created by a potential barrier. The nonrotating ground-state phases are investigated across the superfluid-supersolid phase transition, revealing a particle imbalance between the two rings and a preferential density modulation in the outer ring in the absence of rotation. Near the p
Estuaries are complex environments rich in biodiversity, making it challenging to understand the distribution and occurrence of microplastics due to the multiple variables that can influence the movement of these particles. Based on this, this study evaluated the influence of different environmental aspects on the distribution and transport of microplastics in the surface waters of the Tramandaí R
Transcription factor cooperation is essential for specifying the heterogeneous dendritic cell (DC) lineages that orchestrate adaptive immunity, yet how it drives subset diversification remains poorly understood. Here, we employed a sequential anchored screen of 70 transcription factors using direct cellular reprogramming to identify regulators that specify type 2 conventional DCs (cDC2s) and plasm
Rationally designing and fabricating high-performance core–shell nanostructures for catalytic organic synthesis is significant yet challenging. Here, we report a solvothermal/calcination strategy to prepare novel core–shell iron–aluminum oxide (FeAlOx) nanosphere-based nanoreactors incorporating active heterometals (AHM = Pd, Cu, or Mn). Leveraging the synergistic benefits of their unique core–she
Catalytic activity is improved by reducing particle size, followed by atomic scale structural and chemical design, allowing physical and electronic confinement of chemical conversion centers. These concepts culminate in single-atom catalysts (SACs) where active precious metal atoms are isolated and anchored on the surface of supports and thus fully utilized for chemical conversion. In contrast, me
The coherence factors of quasiparticles in a superconductor determine their properties, including transport as well as their susceptibility to electric fields. In this work, we propose a way to infer the local coherence factors using local transport to normal leads. Our method is based on measuring the local current through a lead as the coupling to a second one is varied; the shape of the current
Abstract Introduction: Epidemiologic studies of hidradenitis suppurativa (HS) from Sweden are limited. The aim of this study was to investigate the prevalence of HS in Lund and Gothenburg, Sweden. Methods: This study was a part of the Global Hidradenitis Suppurativa Atlas (GHiSA) initiative. The study was multicentered and included apparently healthy adults accompanying a patient to the Department
The exponential rise in atmospheric CO₂ driven by human activities is accelerating climate change and causing ocean acidification (OA). While the effects of elevated CO₂ on a wide range of marine species have been well documented, the implications of OA for bivalve aquaculture have received comparatively little attention. Using a multi-level meta-analytical approach, we evaluated the impacts of tw
Investigates memory initiatives in three of the world’s hardest to solve conflicts and how they can be invested with more constructive dynamics Agonistic memory work as a framework for conflict transformation In-depth case studies from Colombia, Israel-Palestine, and Northern Ireland Careful historical tracing of memory politics in zones of protracted conflict Agonistic memory dialogues a
Protein deletions are frequent among both disease-causing and tolerated variants. Several mechanisms at the DNA, RNA and protein levels can lead to deletions. Many deletions are misclassified in the literature and databases, especially when the mRNA is degraded by the cellular quality-control mechanism. We developed a novel predictor for sequence retaining protein deletions, i.e., variants that do
Zirconium hydride is commonly used for next-generation reactor designs due to its excellent hydrogen retention capacity at temperatures below 1000 K. These types of reactors operate at thermal neutron energies and require accurate representation of thermal scattering laws (TSLs) to optimize moderator performance and evaluate the safety indicators for reactor design. In this work, we present an ato
A significant surface wettability transition from hydrophobicity to hydrophilicity after long-term operation is observed in graphite bipolar plates of a proton exchange membrane fuel cell (PEMFC). Extensive in-situ electrochemical characterization was performed to investigate the impact of bipolar plate wettability on the performance and durability of two PEMFCs (named “New cell” and “Old cell”),
Complement activation protects against infection but also contributes to pathological mechanisms in a range of clinical conditions such as autoimmune diseases and transplant rejection. Complement-inhibitory drugs, either approved or in development, usually act systemically, thereby increasing the risk for infections. We therefore envisioned a novel class of bispecific antibodies (bsAbs) which are
Presentationen bjuder på utdrag ut en historisk genomgång av folkmusikforskning i Norden. Syftet är att gå bortom de olika teman som utforskats (till exempel fiolens och dragspelets historia eller folkliga sångtekniker) och även synliggöra de ideologiska trender som vävts in i forskningsprojekten, såväl i design som genomförande och i resultat – eller förväntat resultat. Som ett led i det pågående
