Great reed warblers, Acrocephalus arundinaceus,1 and great snipes, Gallinago media,2 exhibit a diel cycle in flight altitudes—flying much higher during the day than the night—when performing migratory flights covering both night and day. One hypothesis proposed to explain this behavior is that the birds face additional heating by solar radiation during daytime and hence must climb to very high, an
Nanoplastics are emerging environmental contaminants that increasingly threaten soil ecosystems, yet their effects on microbial behavior remain poorly understood. This is mainly due to the lack of experimental tools capable of directly observing microbial dynamics in situ under realistic soil-like conditions. Here, we present a proof-of-concept system that enables real-time, high-throughput monito
Säkerhetsläget i Europa har förändrats drastiskt under de senaste åren, med de två största förändringarna i Rysslands invasion av Ukraina, och NATO:s expandering med Sverige och Finland som nya medlemsstater. Den ökade militariseringen i Europa har också resulterat i att en gammal fråga nu igen dykt upp i den allmänna debatten, nämligen frågan om Åland borde remili-tariseras i syfte att säkra ÖsteThe security in Europe has changed dramatically during recent years, with the two most significant changes being Russia’s invasion of Ukraine, and NATO:s expansion with Sweden and Finland as new member states. The increasing militarization in Europe has also brought back an old question into the public debate, namely if the Åland islands should be re-militarized with the purpose of securing the Ba
Like other Western legal systems, the Swedish legal system constructs objectivity as an unemotional state of being. We argue that the enactment of objectivity in situ relies on objectivity work including emotion management and empathy. Building on qualitative interviews and observations in Swedish district courts, we analyse courtroom interaction through a dramaturgical lens, highlighting tacit siLike other Western legal systems, the Swedish legal system constructs objectivity as an unemotional state of being.

Smart microscopy represents a paradigm shift in biological imaging, moving from passive observation tools to active collaborators in scientific inquiry. Enabled by advances in automation, computational power, and artificial intelligence, these systems are now capable of adaptive decision-making and real-time experimental control. Here, we introduce a theoretical framework that reconceptualises sma

Popular Abstract in Swedish Antalet personer som är amputerade ovanför tålederna i Sverige kan uppskattas till mellan 5000 och 5500. (ca 0.06 % av befolkningen). Största delen av dessa är amputerade pg.a. av kärlsjukdom (≈ 80 %). Antalet årligen nytillkomna benamputerade i Sverige kan uppskattas till mellan 1000-1100 och mindre än 5 % av dessa fall är relaterade till andra orsaker, t.ex. trauma elThe current prevalence of persons amputated at transmetatarsal level or higher in Sweden can be estimated to be between 5000 and 5500 persons (approx. 0.06 % of the population). The majority of these are patients with vascular disease (≈ 80%). In Sweden between 1000 and1100 new amputees can be expect every year. Less than 5% of all amputations will be related to causes other than vascular disease.
Tracking techniques are vital for the understanding of the biology and ecology of organisms. While such techniques have provided important information on the movement and migration of large animals, such as mammals and birds, scientific advances in understanding the individual behaviour and interactions of small (mm-scale) organisms have been hampered by constraints, such as the sizes of existing
Wnt5a is a non-canonical secreted glycoprotein of the Wnt family that plays an important role in cancer development and progression. Previous studies report that Wnt5a is upregulated in prostate cancer and suggested that Wnt5a affects migration and invasion of prostate tumor cell. This study aimed to evaluate the prognostic value of Wnt5a protein expression in prostate cancer tissue and its potent
There is a long history of avian studies investigating the impacts of urbanization. While differences in several life-history traits have been documented, either between urban and rural populations or across generalized urbanization gradients, a detailed understanding of which specific environmental variables cause these phenotypic differences is still lacking. Here, we quantified several local en
The study of biological mechanisms involved in human fetal brain development requires suitable models. To date, most findings have been acquired from animal models that fail to account for human-specific developmental traits. To counteract this limitation, a novel in vitro model is proposed where human pluripotent stem cells are differentiated into a coherent fetal brain tissue in a gradient formi
Cytokines provide signals that regulate immature normal and acute myeloid leukemia (AML) cells in the bone marrow microenvironment. We here identify interleukin 4 (IL4) as a selective inhibitor of AML cell growth and survival in a cytokine screen using fluorescently labeled AML cells. RNA-sequencing of the AML cells revealed an IL4-induced upregulation of Stat6 target genes and enrichment of apopt
In vitro and animal studies suggest that bioactive constituents of coffee and tea may have anticarcinogenic effects against cutaneous melanoma; however, epidemiological evidence is limited to date. We examined the relationships between coffee (total, caffeinated or decaffeinated) and tea consumption and risk of melanoma in the European Prospective Investigation into Cancer and Nutrition (EPIC). EP
Alzheimer’s disease (AD) is the most common cause of dementia, costing about 1% of the global economy. Failures ofclinical trials targeting amyloid-βprotein (Aβ), a key trigger of AD, have been explained by drug inefficiency regardlessof the mechanisms of amyloid neurotoxicity, which are very difficult to address by available technologies. Here, wecombine two imaging modalities that stand at oppos
The YPEL family genes are highly conserved across a diverse range of eukaryotic organisms and thus potentially involved in essential cellular processes. Ypel4, one of five YPEL family gene orthologs in mouse and human, is highly and specifically expressed in late terminal erythroid differentiation (TED). In this study, we investigated the role of Ypel4 in murine erythropoiesis, providing for the f
Antisymmetric, symmetric and standard actuation of acoustofluidic devices were compared in terms of focusability. By imaging the end part of an acoustophoresis separation channel while flowing fluorescent beads through it, we show that beads get more tightly focused by antisymmetric actuation than symmetric and standard actuation at a given electrical input power. This means that antisymmetric act
BACKGROUND: This paper investigates the impact of a non-mandatory and age-specific social distancing recommendation on isolation behaviors and disease outcomes in Sweden during the first wave of the COVID-19 pandemic (March to July, 2020). The policy stated that people aged 70 years or older should avoid crowded places and contact with people outside the household.METHODS: We used a regression dis
Aim: This randomised controlled trial evaluated changes in parental self-efficacy and children's weight, after a Child-Centred Health Dialogue about preventing obesity. Methods: We randomly assigned 37 Child Health Centres in Skåne county Sweden to provide usual care or the dialogue intervention. They included centres from high and low socioeconomic areas. The outcomes were changes in parental sel
BACKGROUND: Diagnostic testing is essential for disease surveillance and test-trace-isolate efforts. We aimed to investigate if residential area sociodemographic characteristics and test accessibility were associated with Coronavirus Disease 2019 (COVID-19) testing rates.METHODS: We included 426 224 patient-initiated COVID-19 polymerase chain reaction tests from Uppsala County in Sweden from 24 Ju
