Current therapeutic strategies for vitamin D-induced hypercalcemia are poorly efficient. Here the authors identify a new interaction between the vitamin D receptor (VDR) and WBP4 controlling the subcellular localization of VDR and show that ZK168281, a VDR antagonist, enhances the interaction between VDR and WBP4 blunting VDR signalling and normalizing calcium levels in vitamin D-intoxicated mice.
DNA-templated synthesis takes advantage of sequence-specific hybridization to accelerate chemical reactions. Here, the authors present templated synthesis controlled through antibody-antigen interactions.
The systematic characterization of C. elegans morphology during development has yet to be performed. Here, the authors produce a 3D atlas of C. elegans morphology from 17 embryos and 54 developmental stages, using an automated pipeline, CShaper (combining segmentation of fluorescently labeled membranes with automated cell lineage tracing).
Maria Antfolk and Kim Jensen discuss how to model intestinal epithelial cell function in the dish and how various physiologically important environmental conditions, for example, extracellular matrix, pressure and flow, can be modelled and how this is applicable to clinical work.
Nano-lamellar materials with ultrahigh strengths are highly desirable for technological applications. Here the authors report a nanolamellar architecturing approach by utilizing coherent L12 structures to achieve ultrahigh strength and ductility in Ni-Fe-Co-Cr-Al-Ti multicomponent alloys.
Vibrio cholerae uses a type VI secretion system (T6SS) to kill neighbouring competitors. Here, Santoriello et al. show that a T6SS gene cluster (Aux3) exists as a mobile, prophage-like element in some environmental strains, and as a stable truncated form in pandemic isolates. They propose that Aux3 acquisition increased competitive fitness of pre-pandemic V. cholerae.
The impact of variant calling algorithms on the analysis of intra-tumour heterogeneity has not been properly quantified. Here the authors measure the variability of 22 pipelines with different variant callers and clustering algorithms for subclonal reconstruction to inform future analyses.
Multiple co-occurring stressors may affect food webs in ways that are not predictable by studying individual stressors. Here the authors apply a network interaction model to a marine food web in the Arctic, finding that nonlinear interactions between stressors can more than double the risk of population collapse compared to simpler simulations.
It has been hypothesized that domestication can occur through the ‘commensal pathway’ in which the domesticate takes advantage of a niche created as a byproduct by the domesticator. Here, Brooker et al. provide evidence for a commensal domestication process between longfin damselfish and mysid shrimps.
Quantitative phase imaging suffers from a lack of specificity in label-free imaging. Here, the authors introduce Phase Imaging with Computational Specificity (PICS), a method that combines phase imaging with machine learning techniques to provide specificity in unlabeled live cells with automatic training.
Bacterial heterodimeric tryptophan-containing diketopiperazines (HTDKPs) are bioactive natural products that are difficult to access chemically. Here, the authors identify a family of three related HTDKP-forming cytochrome P450s and engineer key amino acid residues to produce distinct diketopiperazines frameworks.
Organic light-emitting diodes (OLEDs) can offer an attractive approach for providing light stimulation in high-throughput optogenetics. Here, the authors report a microstructured OLED array that provides local photo-stimulation in Drosophila melanogaster larvae for controlled motor responses.
SARS-CoV-2 can infect cats and dogs, but the extent to which pets are infected in households remains unclear. Here, Patterson et al. test 919 companion animals in northern Italy and find that some dogs and cats from COVID-19 positive households can test positive for COVID-19 neutralizing antibodies, with dogs significantly more likely to do so if they came from COVID-19 positive households.
Here the authors study atomic scale dynamics in water by using X-ray photon correlation spectroscopy. They use a split-and-delay optics with self-seeding of X-rays to generate pulses of enough energy and controlled time delay between two X-ray pulses.
The description of quasicrystal structures by only one repeating unit is desirable. Here the authors experimentally identify a quasi-unit-cell corresponding to a Lück decagon to describe the randomly ordered structure of a decagonal quasicrystalline phase.
The tumour microenvironment provides signals to support leukaemic stem cells (LSC) maintenance and chemoresistance. Here, the authors show that disrupting niche-associated signalling by inhibiting receptor-mediated endocytosis with a dynamin GTPase inhibitor overcomes chemoresistance of LSC.
AlfC transfucosidase is used to modulate fucosylation of glycans decorating monoclonal antibodies. Herein, structural and biophysical characterization reveals the enzymatic mechanism of AlfC and a blueprint for the design of AlfC mutants with novel specificities and functions.
Mechanical strength of in situ assembled nuclear lamin filaments arranged in a 3D meshwork is unclear. Here, using mechanical, structural and simulation tools, the authors report the hierarchical organization of the lamin meshwork that imparts strength and toughness to lamin filaments at par with silk and Kevlar®
ε-Fe2C has been identified as the highly active phase for Fischer-Tropsch synthesis (FTS), but is stable only at low-temperature. Here, the authors show that ε-Fe2C phase can be stabilized even at ~ 573 K by being encapsulated inside graphene layers, and retains high activity in FTS.
It is unclear how a gene regulatory network (GRN) incorporates novelty whilst still maintaining overall stability. Here, the authors provide a comprehensive GRN for endomesoderm specification in the sea star from zygote stage to gastrulation, showing conserved network kernels stabilize evolutionary changes in signaling modes.
