Although magnetic tomography has been used in the past to determine the 3D magnetization of materials its application to thin films remains challenging. Here the authors reconstruct the magnetization of a thin film, enabling the measurement of topological charges of magnetic singularities.
New Zealand implemented stringent COVID-19 control measures early after identification of its first case. Here, the authors perform whole genome sequencing of samples taken until 22 May 2020 and find high viral diversity indicative of multiple separate introductions and limited community transmission.
RIPK1 is a critical kinase which mediates necroptosis, apoptosis and inflammation. Regulation of RIPK1 by ubiquitination is being intensively investigated. Here, the authors made knock-in RIPK1-K612R mice and demonstrate that this mutation alters the RIPK1 ubiquitinylation pattern and inhibits its prodeath kinase activity in response to TNFα but sensitizes cell death to TLRs signals.
Mammalian skeletal muscle is composed of multinucleated myofibers, containing hundreds of nuclei that coordinate cellular function. Here, the authors show that single-nucleus RNA-sequencing reveals rare and emergent myonuclear populations, and uncovers dynamic transcriptional heterogeneity in development and aging.
RNA-sequencing data from tumours can be used to predict the prognosis of patients. Here, the authors show that a neural network meta-learning approach can be useful for predicting prognosis from a small number of samples.
Standard benchmarking of single-molecule localization microscopy cannot quantify nanoscale accuracy of arbitrary datasets. Here, the authors present Wasserstein-induced flux, a method using a chosen perturbation and knowledge of the imaging system to measure confidence of individual localizations.
Signal processors based on programmable photonic circuits will enable many future applications employing a common hardware platform. The authors present the architecture and two approaches to management automation to enable self-configuration and optimization of such photonic integrated circuits.
We classically consider the T cell compartment divided into cytotoxic CD8+ T cells and multiple, different helper CD4+ T cell subsets. Here the authors demonstrate that distinct memory CD8+ T cell subsets phenotypically inhabit CD4+ T cell like populations including some with helper-like characteristics.
Histopathological images are a rich but incompletely explored data type for studying cancer. Here the authors show that convolutional neural networks can be systematically applied across cancer types, enabling comparisons to reveal shared spatial behaviors.
Dynamic arrangement of epigenetic modifications such as repressive H3K27 methylation is essential for zygote development. Here the authors show that establishment of genome-wide H3K27me3 in zygotes requires EZH2, that EZH1 partially compensates for EZH2 loss, and that EHMT1 is involved in H3K27me2 establishment.
Lithium-rich layered material deserves in-depth understanding because it has large capacity enabled by both cation and anion activities. Here, authors apply 3D spectro-tomography with nano resolution to reveal the multi-layer morphology and depth-dependent transition metal valence distribution associated with oxygen redox.
The thymus is essential for T cell maturation and selection, and thymic defects result in severe immune problems. Here the authors identify a thymus cell population that is expandable in vitro, and can repopulate natural thymic matrix to generate tissue that supports mature T cell development in vitro and in vivo.
Here, the authors design macroscopic multi-layered graphene fibres with light-emission and -detection dual functionality in the mid-infrared range, offering megahertz modulation frequencies and bidirectional data transmission operation.
Laser wakefield accelerators are compact sources of ultra-relativistic electrons which are highly sensitive to many control parameters. Here the authors present an automated machine learning based method for the efficient multi-dimensional optimization of these plasma-based particle accelerators.
lncRNAs are transcriptional regulators, but little is known of them functioning as negative feedback regulators of inflammation in humans. Here, the authors show that the human lncRNA LUCAT1 sequesters STAT1 to limit JAK/STAT signaling and the inflammatory response to viral infection or TLR stimulation in myeloid cells.
Quantifying forest degradation and biodiversity losses is necessary to inform conservation and restoration policies. Here the authors analyze a large dataset for the Atlantic Forest in South America to quantify losses in forest biomass and tree species richness, functional traits, and conservation value.
Here, the authors characterize the effects of Lactobacillus casei strains engineered to express pathogenic or non-pathogenic Listeria adhesion protein (LAP) in systemic colonization and protection against lethal Listeria monocytogenes infection in mice and show that these engineered strains can colonize the intestine and prevent dissemination of L. monocytogenes and protect against lethal infection while promoting immunomodulatory effects.
The gut microbiota may contribute to depression, but the underlying mechanism is not well understood. Here the authors use a mouse model of stress induced depression to demonstrate that behavioural changes conferred by fecal transplant from stressed to naïve mice require the endocannabinoid system.
The systems-level regulatory structure underlying gene expression in bacteria can be inferred using machine learning algorithms. Here we show this structure for Bacillus subtilis, present five hypotheses gleaned from it, and analyse the process of sporulation from its perspective.
Mutations in the RNA binding protein FUS cause amyotrophic lateral sclerosis (ALS). Here the authors characterize FUS-binding to U1 snRNP and show that ALS-associated FUS aberrantly contacts U1 snRNA which interferes with its biogenesis pathway.
