Methane dry reforming not only utilizes two potent greenhouse gases of methane and carbon dioxide, but also provides a valuable feedstock for the production of chemicals. However, this process has been heavily hindered by high operating temperature and coke formation with catalyst deactivation over the last century. Herein, we propose an approach whereby concentrated-solar catalytic methane dry re
Brain organoid technology has seen significant development in recent years. This self-organized, three-dimensional, organ-oriented brain tissue model can recapitulate the process of neurogenesis and consists of diverse cell types and cellular architecture. Transplanting brain organoids in vivo could be a potential tool from bench to clinical research and has been studied for many purposes. To inve
Background: Graft rejection (GR) is common complication after haploidentical hematopoietic cell transplantation (haplo-HCT). There are only a few studies describing the clinical presentation and potential risk factors of GR, and the optimal rescue strategy is not established. Objectives: To evaluate the cumulative incidence and potential risk factors for GR following haplo-HCT, and to compare surv
This study presents a cryogenic resonant radio frequency (RF) transmitter coil design for magnetic field generation that utilizes electromechanical switches to match and tune the resonance frequency with capacitor banks in situ. The design enables magnetic field generation at any frequency across a wide frequency range of 25-140 MHz (560% tuning range) while operating at 1.5 K. Magnetic field gene
BACKGROUND: The cross-sectional association between cerebral tissue oxygen saturation (SctO 2) and heart failure (HF) has been previously studied, but the prognostic significance of SctO 2 in HF remains uncertain. This study aimed to assess the role of SctO 2 as a risk factor for all-cause mortality and rehospitalisation, as well as to explore the cross-sectional association between physical activ
Stem cell sources capable of producing appropriate cells for replacement will be necessary for functional repair of the injured brain. Here, we have determined whether transcription factor programming of human embryonic stem (hES) cells can be used to generate layer-specific cortical neurons capable of integrating into the stroke-injured rat cortex. Human embryonic stem cells were programmed via o
The medical profession plays a crucial role in tackling the health impacts of climate change and in promoting a green transition of society and the health sector. Despite this, opportunities for action are still quite unknown within the profession, and no mandatory education is required in interns' or residents' education. Medical schools, on the contrary, both in Sweden (due to legislation) and a
Direct reprogramming of somatic cells into induced neurons (iNs) has become an attractive strategy for the generation of patient-specific neurons for disease modeling and regenerative neuroscience. To this end, adult human dermal fibroblasts (hDFs) present one of the most relevant cell sources. However, iNs generated from adult hDFs using two-dimensional cultures are difficult to maintain in vitro
We use a closed-loop algorithm to accurately program hafnium zirconium oxide (HZO) ferroelectric tunnel junctions (FTJs) to arbitrary chosen target conductance values. The key enabler is suppression of conductance growth. We have identified two different mechanisms contributing to the total conductance of FTJs. By controlling both, we demonstrated an up to threefold increase of the usable conducta
A memlumor is an innovative neuromorphic luminescent device with a state-dependent photoluminescence quantum yield (PLQY) designed for optical neuromorphic computing applications. Metal halide perovskite memlumors leverage charge trapping and photodoping to modulate the PLQY, making it dependent on the excitation light history. Here, we demonstrate the ability of perovskite memlumors to classify t
High-performance X-ray detectors are essential for 3D X-ray imaging in computed tomography (CT), but conventional systems require high radiation doses to achieve fine resolution. All-In-One (AIO) Cu(I) halide complexes, capable of forming both ionic and coordinate bonds within a single structure, offer efficient scintillation at lower doses, yet their performance remains limited by nonradiative en
This paper shows a FeFET-based analog multi-level unit cell for computing-in-memory applications for Deep Neural Networks (DNN). The FeFET-based unit cell performs input-weight multiplication with a Back-End-Of-Line (BEOL) ferro-electric HZO FeFET device on top of standard 180 nm CMOS circuits. The unit cell works with a feedback mechanism which combines an in-house FeFET device to store weights a
Analyzing kinetic experiments on protein aggregation using integrated rate laws has led to numerous advances in our understanding of the fundamental chemical mechanisms behind amyloidogenic disorders such as Alzheimer's and Parkinson's diseases. However, the description of biologically relevant processes may require rate equations that are too complex to solve using existing methods, hindering mec
Studying photoluminescence (PL) is essential for understanding and engineering light-emitting nanomaterials. Heterogeneous samples, such as thin films and microstructures, require characterization of the spatial distribution of PL intensity, spectra, lifetimes, and photon correlations at the microscale under variable temperatures. Here we describe a cryo-optical setup for micro-PL imaging, spec

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.

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
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
