Raman probes which operate in the cellular silent region are of interest for live cell imaging. Here, the authors report on the development of a water soluble polydiacetylene Raman probe with enhanced Raman signal in the silent region which can be functionalised for organelle targeting and demonstrate application.

Cratons represent the ancient cores of continental plates and are generally thought to have been stable since the Archean. Here however, the authors combine seismic analysis with kimberlite data to infer complete destruction of cratonic lithosphere in some places of the African continent.

Quantification and characterization of circRNAs in sequencing data remains challenging, hindering efforts to understand their roles and regulation. The algorithm introduced here enables accurate circRNA quantification and permits insight into competitive splicing between linear and circular isoforms.

Identifying the composition of multiphase inorganic compounds from XRD patterns is challenging. Here the authors use a convolutional neural network to identify phases in unknown multiphase mixed inorganic powder samples with an accuracy of nearly 90%.

Identification of cancer driver genes, especially those that can act as tumour suppressors or oncogenes depending on context, remains a challenge. Here, the authors introduce Moonlight, a tool that integrates multi-omic data to address this challenge and identify numerous dual-role cancer genes.

DNA methylation is associated with complex traits and the expression of genes and proteins. Here, Zaghlool et al. perform epigenome-wide association studies for 1,123 plasma proteins, replicate obtained protein (p)QTMs in an independent cohort and find overlap of pQTMs with expression QTMs and previously reported disease associations.

We lack effective treatment for half of children with high-risk neuroblastoma. Here, the authors introduce an algorithm that can predict the effect of interventions on gene expression signatures associated with high disease processes and risk, and identify and validate promising drug targets.

The development of microscale materials with cell-like functions and collective behaviors is an important milestone in bottom-up synthetic biology. Here the authors employ a bio-inspired inorganic synzyme to construct a micro-compartment with multi-functional activity providing a step towards the development of protocell reaction networks.

The authors combine ab-initio density functional theory with tight-binding calculations to investigate the optical absorption resonances of armchair carbon nanotubes and zigzag graphene nanoribbons, and show that an atlas of carbon nanotubes optical transitions can be mapped to an atlas of optical resonances of zigzag graphene nanoribbons.

Designing low power consumption and fast operation electronic phase-change devices remains a challenge. Here, the authors demonstrate the reversible displacive transformation in polycrystalline MnTe films to enable resistive switching via fast Joule heating for fast nonvolatile memory applications.

Scientific complementary metal-oxide semiconductor (sCMOS) cameras have advanced the imaging field, but they often suffer from additional noise compared to CCD sensors. Here the authors present a content-adaptive algorithm for the automatic correction of sCMOS-related noise for fluorescence microscopy.

The axon initial segment (AIS) is a specialized location in neurons with clustered ion channels which regulates the distribution of neuronal materials. Here, the authors use proximity biotinylation to examine the AIS proteome and better define its molecular organization.

A robust platform to study modular polyketide synthases (PKSs) in vitro is still unavailable. Here, the authors report the reconstitution of the venemycin PKS, engineer hybrid venemycin/pikromycin PKSs, and obtain much improved yields through employing the updated module boundaries.

New World arenaviruses utilize the cellular transferrin receptor 1 (TfR1) to enter host cells. Here, the authors develop a TfR1-mimetic immunoadhesin, Arenacept, that targets viral spike complexes and exerts effective pan-reactive neutralization against pathogenic mammarenaviruses.

Here, the authors report ultrasensitive negative capacitance phototransistors based on MoS₂ regulated by a layer of ferroelectric hafnium zirconium oxide film to demonstrate a hysteresis-free ultra-steep subthreshold slope of 17.64 mV/dec and specific detectivity of 4.75 × 10¹⁴ cm Hz^1/2 W⁻¹ at room temperature.

Relapse is a limitation for the efficacy of the anaplastic lymphoma kinase (ALK)-inhibitor alectinib in ALK-rearranged lung cancer. Here, the authors show that YAP1 activation upon alectinib treatment leads to therapy resistance and that inhibiting both YAP1 and ALK leads to longer tumor remission in mice.

The existence of regular decadal or longer climate oscillations has been the subject of intensive discussion. Here, statistical analysis of observational data and a large ensemble of model simulations show no evidence for longer-term internal oscillations that are distinguishable from climatic noise.

Long-chain alcohols synthesis from syngas conversion is a promising route for the production of high-value chemicals. Here the authors show that a heterogeneous Fe₅C₂/Cu catalyst derived from layered double hydroxides precursor exhibits excellent performance with a space time yield of 0.101 g g_cat⁻¹ h⁻¹ at a low pressure of 1 MPa.

In Arabidopsis, LZY proteins are involved in specifying the angle of root growth relative to the direction of gravity. Here the authors identify RLD1, a LZY-interacting protein that is recruited to the plasma membrane in a polar manner and is required to establish asymmetric auxin transport and set root angles.

Cancers arising from the gastric squamous-columnar junction have high incidence and are characterized by a poor prognosis. Here, the authors use genetic mouse models to show that loss of p53 and Rb1 expression results in preferential tumour development at the gastric squamous-columnar junction that contains a large pool of osteopontin responsive Lgr5-CD44+ cells.
