The ability to perform nonlinear feedforward operations - that is, conditional operations controlled by nonlinear function of the measurement outcomes - is still a missing ingredient for measurement-based quantum computation. Here, the authors fill this gap using nonlinear electro-optical feedforward and non-Gaussian ancillary states.
It has generally been considered that MOM1, a transcriptional silencing factor in plants, mediated silencing is independent or downstream of DNA methylation. Here, the authors show that MOM1 complex recruits the RdDM machinery through MORC6 to establish de novo DNA methylation in Arabidopsis.
The Kondo hybridization typically occurs in heavy-fermion systems containing f electrons, although recently it has been reported in d-electron systems. Kim et al. report spectroscopic evidence of the Kondo hybridization in FeTe and discuss it role in the mechanism of the magnetic order.
Protein lysine methylation plays important biological roles but its experimental characterization is limited by the lack of suitable mimetics of methylated and unmethylated lysine among the natural amino acids. Here, we summarize the consequent challenges and discuss alternative approaches for biochemical and cellular lysine methylation studies.
Understanding the utility of SARS -CoV-2 vaccination platforms and strategies through the emerging pandemic and beyond are critical to understanding the efficacy of such interventions. Here the authors assess nasal delivery of an influenza virus based viral vector for vaccination against SARS-CoV-2 in a hamsters model and assess the induced immunity.
The consequences for insects of sub-lethal levels of ambient particulate matter pollution exposure have not received much attention. Here, the authors show that accumulation of particulate matter on houseflies severely compromises their olfactory and other key physiological functions.
Chemokines are small proteins secreted at sites of injury. Here, the authors describe the structure of the chemokine receptor CXCR1 bound to chemokine CXCL8, solved by cryo-EM. The model helps explain the ligand preferences of this receptor.
Forest losses and gains are highly dynamic processes. Here, the authors present a forest fragmentation index to map distribution and temporal changes of forest fragments globally, revealing major trends and patterns during the first two decades of the 21st century.
Intra-tumoral heterogeneity and cell-state plasticity contribute to the development of therapeutic resistance in glioblastoma (GBM). Here the authors use two deep learning models to predict spatial transcriptional programs and prognosis from histology images in GBM.
Increased global land precipitation, due to the atmospheric feedbacks of large-scale bioenergy cultivation, may partially compensate the water consumption by such rainfed bioenergy crops at the global scale.
Inhibition of bacterial cell wall synthesis by β-lactam antibiotics results in a loss of cell wall integrity, but cells die via a combination of downstream events involving metabolic perturbations and oxidative damage. Here, Kawai et al. identify key enzymatic steps that stimulate the generation of reactive oxygen species and highlight the role of iron homeostasis in the lethal effects mediated by oxidative damage.
Minimally invasive irreversible electroporation shows some therapeutic promise in irresectable pancreatic cancers that are notorious for poor survival. Here authors combine this with administration of a hydrogel microsphere vaccine that augments the antigen presentation T cell response cascade that naturally initiates following ablation.
Traditional optical microscope, while bulky, often fails to deliver optimal performance. Here, the authors have engineered an integrated microscope of 0.15 cm3 in volume and a weight of 0.5 g, which outperforms a commercial microscope and can be seamlessly integrated with a smartphone.
Hydrodynamically coupled rotors can be used to describe interactions ranging from molecular machines to atmospheric dynamics. Modin et al. show that optically-driven rotors in a non-tweezing beam can freely diffuse while spinning asynchronously and develop an analytical hydrodynamic model to explain.
Reproducible and scalable data processing is key to the progress of metabolomics. Here, the authors present a software tool that offers predictable metabolomics feature detection and improved computational performance in large datasets.
There is a need for methods that allow the analysis of single-cell long-read sequencing data without depending on known barcode lists or short-read sequencing. Here, the authors develop scNanoGPS, a tool that can independently deconvolute long reads into single cells and single molecules, and apply it on tumour and cell line data.
Hyperbolic phonon polaritons (HPhPs) in anisotropic van der Waals materials hold promise for nanophotonic applications, but their far-field characterization remains challenging. Here, the authors demonstrate the application of Raman spectroscopy in a backscattering configuration to determine the dispersion of HPhPs in thin GaSe crystals.
An outbreak of Mpox in the UK began in May 2022 and peaked in July. In this modelling study, the authors show that the decline in cases was likely due to behavioural changes among high-risk populations, whilst vaccination could prevent a rebound.
