Polar growth and cell shape determination in mycelium-forming Streptomyces bacteria depends on the function of a polarly localised multiprotein complex that directs cell wall synthesis – the polarisome. This complex assembles around the essential cell polarity determinant DivIVA, alongside other largely unknown components. We report here the discovery of a conserved hybrid histidine kinase-like pr
Fibroblasts are dynamic structural cells that direct both beneficial tissue repair and pathological organ fibrosis through interactions with tissue-resident type 2 lymphocytes (T2Ls) and type 3/17 lymphocytes (T3Ls). The cytokines interleukin-13 (IL-13) and IL-17A, produced by T2Ls and T3Ls, respectively, are linked to both tissue inflammation and fibrosis, but how their spatial positioning influe
The Binarity at LOw Metallicity (BLOeM) survey is an ESO large programme designed to obtain multi-epoch spectroscopy for 929 massive stars in the Small Magellanic Cloud (SMC). It will provide binary fractions and orbital configurations of binary systems and search for dormant black hole binary candidates (OB+BH). We present projected rotational velocities (v sin i) of all sources, and, using the m
Introduction: Exposure to high acoustic noise levels generated during 7 Tesla (T) magnetic resonance imaging (MRI) may affect auditory function. To better understand these effects, this study examines how such noise exposure influences outer hair cell function in healthy adults, with a focus on the efficiency of a dual hearing protection method. Methods: In this within-subjects longitudinal study,
Growth and immune development—fundamental parts of any organism's ontogeny—depend critically on nutrient availability, particularly on essential amino acids that support protein synthesis and physiological processes. However, environmental variation can reduce prey diversity and nutrient quality, producing suboptimal diets that lack essential amino acids, potentially constraining development. In t
The Bcl-2 family of proteins governs mitochondrial outer membrane (MOM) permeabilization, a critical step in apoptosis that is dysfunctional in many cancers. Although cellular studies have long implicated direct interactions between the pore-forming apoptotic Bax protein and its opponent, the antiapoptotic Bcl-2 protein in apoptosis regulation, the underlying basic principles behind this control r
Rapid adoption of artificial intelligence methods in breast imaging research emphasizes the need for large, appropriately curated image databases for development and validation. For digital breast tomosynthesis (DBT), there are few public databases with only limited lesion annotation. Recently, we have developed Malmö Breast ImaginG (M-BIG), a large database of 104 791 women screened at Skåne Univ
More than six decades ago, Aníbal Pinto Santa Cruz (1959) published his pivotal work, Chile, a case of frustrated development. Almost 65 years later, this concept has been reborn under the massive protests and social unrest of 2019, the COVID pandemic, and the new lithium cycle. Chile, the former “Latin American Miracle,” has become an unstable and troublesome state, not particularly different fro
Molecular oxygen activation at single transition metal atom sites is critical for catalysis but remains challenging to control. Here we investigate a manganese–cobalt bi-metallic coordination network on graphene, where Co(i) atoms are tetracoordinated by nitrogen. Combining density functional theory with in situ infrared-visible sum-frequency generation and ambient-pressure X-ray photoelectron spe
Cryo-scanning electron microscopy (CryoSEM) permits the preparation and detailed imaging of bulky samples while keeping them in a hydrated state. For plant biology, cryofractures give information on cell ultrastructure and tissue organisation within a much larger context that is the whole organ or organism. To date, a method to locate fluorescence reporters on the cryofracture has not been reporte
Construction robot prototype for onsite work. Consists of an ABB IRB4600 mounted on a spindle crane chassi for mobility. Housed in a container for weather protection and logistics.
Om framtiden i Gulfstaterna mörknar efter kriget kommer drömmen sannolikt inte göra det. Den lär flöda vidare – till nästa plats där kapitalet lovar fart, glitter och gränslös framgång. Sofia Ulver undersöker varför svenska ungdomar drömmer sig bort i digitala flöden och utopiska bildvärldar.
Background: Limited evidence exists for effect modification of genetic characteristics on the associations of food consumption and incident type 2 diabetes (T2D). Objectives: We aimed to investigate whether the food-T2D association would vary by genetic susceptibility to metabolic traits. Methods: We analyzed data from 9542 incident T2D cases and a subcohort of 12,477 participants nested within th
Objective: Degenerative orthopedic diseases (DODs) such as osteoporosis, osteoarthritis, spondylosis, spinal stenosis, and disc herniation are common disorders. Both common and rare genetic risk factors may contribute to DODs, but few large-scale whole-exome sequencing studies elucidating the contribution of rare variations to DODs have been published. The updated version of the Astra Zeneca porta
The molecular mechanisms governing internal fluctuations in intrinsically disordered protein (IDP) assemblies are crucial to the stability and dynamics of both regulated and aberrant toxic cellular aggregates, but remain poorly understood. By comprehensively combining high-resolution quasi-elastic neutron scattering with all-atom molecular dynamics simulations, we probe the motions of β-casein, a
Amyloid-β (Aβ) accumulation is a hallmark of Alzheimer’s disease. Cerebral Aβ deposition is attenuated by a functional glymphatic system, in which perivascular entry of cerebrospinal fluid (CSF) and its exchange with interstitial fluid mediate solute clearance. Parenchymal border macrophages (PBMs), positioned along glymphatic pathways, are emerging as important players for glymphatic clearance. H
