Editorial for the special issue of "Small Structures"

Depiction of sinusoidal displacement in nanocrystal superlattices through a minimum of geometric shapes and contrasting colors. This cover pays homage to the Bauhaus movement, celebrating human-made craftsmanship, clarity, and accessibility in scientific design, and remains faithful to its fundamental principle: less is more.

2023 JCP Emerging Investigators Special Collection: Tuning perovskite nanocrystal superlattices for superradiance in the presence of disorder

Oligodendrocyte precursor cells (OPCs) display functional plasticity beyond myelination. Kuwata et al. explore how hypoxia shapes OPC features after ischemic stroke. Combining single-cell transcriptomics with in vivo and ex vivo models, they reveal oxygen-dependent OPC phenotypes promoting angiogenesis and remyelination, highlighting OPC versatility and potential for novel stroke cell therapies.

Aducanumab, a human IgG1 antibody with plaque-clearing effects and modest clinical benefit, binds selectively to aggregated Aβ via the N-terminal region. Yet, the molecular details of how the antibody engages Aβ1-42 fibrils remain unresolved. Using magic-angle spinning NMR, we show that binding of aducanumab preserves the overall architecture of the Aβ1-42 fibril core while inducing significant st

Since its inception in 1998, the Cuneiform Digital Library Initiative (https://cdli.earth) has become the global authority index for inscribed artifacts of the cuneiform world, providing an essential reference for a corpus of half a million historical documents that form an important part of the world’s written heritage. The CDLI infrastructure is now foundational to the study of the history of th

Background: Air pollution is a known risk factor for chronic respiratory diseases, including asthma and chronic obstructive pulmonary disease (COPD). However, evidence regarding the role of black carbon (BC) remains mixed and sparse. This study aimed to examine the association of long-term exposure to air pollution, focusing on BC, with incident asthma and COPD in adults. Method: We followed 28,73

Objective Delivery of a small for gestational age (SGA) infant is a common pregnancy complication among women with SLE. Although disease activity and autoantibodies such as anti-Smith and anti-ribonucleoprotein associate with SGA, underlying pathological mechanisms remain unclear and reliable predictors are lacking. To address this, we applied a proteomic approach to identify proteins associated w

Background Preserved ratio impaired spirometry (PRISm) and restrictive spirometry pattern (RSP) are associated with increased morbidity and mortality, but the underlying mechanisms are unclear. Impulse oscillometry (IOS) measures small airway function more sensitively than spirometry. We aim to study the prevalence of abnormal IOS findings in relation to three spirometry patterns (obstructive, PRI

BACKGROUND: Cardiovascular calcification is a significant predictor and contributor to cardiovascular diseases. Vascular smooth muscle cell (SMC)-derived extracellular vesicles (EVs) play a crucial role in microcalcification formation. EVs can originate from the endosomal system, and PIKFYVE (1-phosphatidylinositol 3-phosphate 5-kinase), a lipid kinase, plays a key role in endomembrane maturation.

Lifetimes of photoexcited charge transfer (CT) states in transition metal chromophores are influenced by low-lying ligand field (LF) excited states, especially for 3d metal complexes. To manipulate interactions between LF and CT states, it is important to be able to control LF excited state energies using tunable synthetic variables. In this report, we use Fe 2p3d L3-edge resonant inelastic X-ray

IntroductionSport-related concussion (SRC) is a pressing issue in Para sport, yet biomechanical mechanisms remain poorly understood. Athletes with visual impairment face elevated risks due to sport-specific demands, such as frequent collisions in blind football. This pilot study examined head acceleration responses in blind football players compared with non-disabled football players, and between

While the multiexciton dynamics in semiconductor nanocrystals is widely explored, to determine the absorption cross sections for multiexcitons of varying order is still a challenge. In this study, we performed pump–repump–probe transient absorption (ppp-TA) spectroscopic measurements on CdSe@CdS nanorods to gain insights into the absorption cross sections for multiexcitons. By tuning the pump–repu

Introduction: It is well known that urinary tract infection (UTI) during pregnancy is associated with preterm birth, but information about the risk of preterm birth depending on gestational week of infection is sparingly described in the literature. Material and Methods: An observational study based on data from Swedish registers including women giving birth 2014–2020 (n = 684 595). Pregnant women

Objective: To describe longitudinal changes of Magnetic Resonance Imaging (MRI) features in the medial vs lateral tibiofemoral (TF) and patellofemoral (PF) compartments, in knees with no radiographic osteoarthritis (OA) at baseline. Design: In 340 individuals from the Osteoarthritis Initiative aged 45–55 years (51% women) with 430 knees at risk for OA and 250 not at risk, we assessed MRI scans of

The clustering of certain proteins into oligomers and fibrils, known as amyloids, underlies the pathology of diseases such as Alzheimer’s disease, Parkinson’s disease, and type 2 diabetes. These processes are counteracted by the cellular protein quality control system, which includes molecular chaperones that interact with disease-associated proteins. One such chaperone is DNAJB6b, which has gaine

Background: Pro-neurotensin (pro-NT) is the stable circulating precursor of neurotensin (NT), a neuropeptide expressed mainly in the central nervous system and small intestine that regulates key physiological processes like fatty acid absorption in the gut and suppresses appetite via central mechanisms. Studies in NT-deficient mice and humans implicate NT in obesity and insulin resistance, highlig

An autonomous service robot should be able to interact with its environment safely and robustly without requiring human assistance. Unstructured environments are challenging for robots since the exact prediction of outcomes is not always possible. Even when the robot behaviors are well-designed, the unpredictable nature of the physical robot-object interaction may lead to failures in object manipu
