Pancreatic ductal adenocarcinomas (PDAC) exhibit complex morphologies challenging to capture in organoid models. Here, the authors develop PDAC organoids that can recreate branched structures and, with the use of a minimal mathematical model, shed light to pathways and processes directing the dynamics of self-organization and branching morphogenesis.
The role of hypoxia inducible factors in infection and immune response is unclear. Here, the authors study their impact on the regulation of T cells responses during Mycobacteria tuberculosis infection using transcriptomics, flow cytometry and in vivo infection.
Silicon is an abundant element on earth and is perfectly compatible with the well-established CMOS processing industry. Here, Sun et al. demonstrate multifunctional neuromorphic devices based on silicon nanosheet stacks, bringing silicon back as a potential material for neuromorphic devices.
Gram negative microbes strategically equip lipopolysaccharides with O antigens to expand the extracellular envelope. Here, the authors examine how the O antigen is captured by a special class of ABC transporters containing a carbohydrate-binding module accessory.
Current wearable solutions for Virtual Reality (VR) have limitations of complicated structures and large driven power. Here, the authors report a highly integrated ring consisting of multimodal sensing and feedback units for augmented interactions in metaverse.
Critical-sized bone defects still present clinical challenges. Here the authors show that transplantation of neurotrophic supplement-incorporated hydrogel grafts promote full-thickness regeneration of the calvarium and perform scRNA-seq to reveal contributing stem/progenitor cells, notably a resident Msx1+ skeletal stem cell population.
Particulate methane monooxygenase (pMMO) is the main enzyme used by methanotrophs. Here, the authors determined the native structure of pMMO by cryo-electron tomography, revealing lipid-stabilized features and a higher-order hexagonal array arrangement in intact cells.
Designing in-sensor computing systems remains a challenge. Here, the authors demonstrate artificial optical neurons based on the in-sensor computing architecture that fuses sensory and computing nodes into a single platform capable of reducing data transfer time and energy for encoding and classification.
The mechanisms underlying the pathogenesis of vaccine-induced immune thrombotic thrombocytopenia (VITT) remain unclear. Here the authors show that anti-PF4 antibodies are responsible for the activation of platelets and neutrophils, and blockage of FcγRIIa or NETosis in vivo can prevent thrombosis.
The hepatitis B vaccine is recognised as the most effective approach in reducing hepatitis-B-related morbidity; vaccine-escape mutations are however capable of infecting vaccinated individuals. In this work, authors aim to establish a hepatitis B vaccine candidate, which they assess in rhesus macaques in terms of efficacy and safety.
While water electrolysis represents a promising means for renewable hydrogen production, the catalysts needed must be efficient at high current densities. Here, authors show rhodium nanocrystals on graphdiyne to efficiently evolve hydrogen from saline water.
Hemochromatosis is a metabolic disorder caused by mutations in the HFE gene. Here, the authors show that a single administration of AAV8 vectors expressing an Adenine Base Editor facilitates efficient in vivo gene correction in hepatocytes and leads to improvement of iron-specific parameters in the liver and the blood in mouse models of the disease.
Fabrication of efficient narrowband near-infrared photodetectors remains a challenge. Here, Liu et al. show a facile and general approach for achieving a sub-50 nm response by intentionally n-doping an optically-thick nonfullerene photodiode using an electron-donating amine-interlayer.
The selective assembly of μm-to-mm sized components is challenging because of the short-ranged molecular recognition. Here, the authors demonstrate a self-sorting mechanism to automatically identify the surface chemistry via additivity and competence between long-ranged magnetic/capillary forces.
Immune system function declines with age, a consequence of defects in hematopoietic stem cells (HSCs). Here the authors show that TAZ buffers age-related loss of PU.1 activity to maintain HSC functionality and identify the surface protein Clca3a1 as a marker of “young-like” HSCs, even in old mice.
The knowledge of quantum numbers of the edge modes is essential for understanding fractional Hall states containing counter-propagating downstream and upstream modes. Here the authors identify the edge quantum numbers by probing a crossover from non-equilibrated to equilibrated edge mode regime in thermal conductance.
Epithelial-mesenchymal transition (EMT) is a complex process involved in organogenesis. Here, the authors show that the transcription factor EB (TFEB) regulates EMT in epicardium during heart development by tuning sensitivity to TGFβ signaling.
Using paired reconstructions of seawater pCO2, temperature, and nutrient utilization, Dai et al. show underappreciated influences of the solubility pump on deglacial Subantarctic surface-water pCO2 variabilities compared to the biological pump.
Altered mechanosensation by application of capsaicin to the skin is thought to be spinally mediated. Here, the authors use Ca2+ imaging in spinal neurons and develop a cell profiling approach to identify populations involved in central sensitization.
Establishing methods to access the chemical space that lies beyond canonical terpenoid biosynthesis will increase the applications of isoprenoids. Here, the authors reconstruct the modular structure of terpene biosynthesis on 16-carbon backbones by engineered yeast and synthesize 28 different unique terpenes.
