Extracting signals from noise is challenging in single-particle catalysis. Here, the authors use deep learning to enhance mass spectrometry, enabling detection of reactions on single nanoparticles.

Spontaneous low-frequency oscillations, which are a feature of biological systems, are challenging to engineer into microrobotic systems. The authors discover a mechanism for asymmetry-induced order and realise electrical and mechanical oscillations in a particle collective to power a microrobotic arm.

Organic neural implants hold considerable promise for biocompatible neural interfaces. Here, the authors employ polymer-based organic electrochemical diodes and transistors to develop neuron-sized complex circuits, enabling multiplexing without crosstalk and demonstrate that, when integrated onto ultra-thin plastic, these circuits achieve high performance while maintaining minimal invasiveness.

Leaves and tissues contain three-dimensional networks of fluidic channels, but similar artificial self-assembling systems have not yet been produced. Jamalet al. develop methods to produce three-dimensional microfluidic networks with curved geometries from the self-assembly of photopatterned polymers.

Nanofluidic scattering microscopy enables label-free, quantitative measurements of the molecular weight and hydrodynamic radius of biological molecules and nanoparticles freely diffusing inside a nanofluidic channel.

The success of Chimeric antigen receptor (CAR) T-cell therapy in solid tumours is hampered by the scarcity of suitable targets and suboptimal activation of the engineered T cells in the hostile microenvironment of the tumours. Here authors identify CD276 as target in childhood rhabdomyosarcoma, which, when combined into a bicistronic construct with a known target, FGF4R, allows enhanced tumour killing.

Shape transformation without the need for external devices or wires is desirable for soft robotics, but challenging to achieve. Here, the authors report the development of actuators capable of shape changes by polymerization and depolymerization of DNA activator sequences.

There is lack of therapies targeting the PAX3-FOXO1 fusion oncogene in fusion-positive rhabdomyosarcoma (FP-RMS). Here, the authors identify and characterise an inhibitor with highest inhibition of histone lysine demethylase 3B that suppresses PAX3-FOXO1 activity in FP-RMS.

Many phototransistors are multi-component systems with inorganic materials or involve faradaic processes that can be irreversible. Using a single photoactive polymer, Druet et al. report a reversible, water-compatible n-type photoelectrochemical transistor with potentiometric photodetection and current modulation.

Electrospray deposition is a promising technique for depositing functional coatings at the micro-/nano-scale. Here, the authors establish the necessary conditions for high efficiency electrospray deposition of small targets, establishing promise as an alternative to other conformal coating methods.

Electron-beam lithography is often used for patterning of asymmetric metal electrodes for nanoscale devices, but suffers from several limitations. Here, the authors report a new adhesion lithography process, which allows for high-throughput and simple fabrication of nanogap metal electrodes.

Quadrupoles have many engineering applications, but experimental observations of fluidic multipoles have not been reported. This study presents an experimental two-dimensional microfluidic quadrupole, a theoretical analysis consistent with observations, and a first application as a channel-free floating gradient generator.

Plant diversity stabilizes grassland soil temperature by boosting soil organic carbon and increasing plant leaf area, according to an 18-year plant diversity experiment.

Whole-genome sequencing analysis of individuals with primary immunodeficiency identifies new candidate disease-associated genes and shows how the interplay between genetic variants can explain the variable penetrance and complexity of the disease.

A metalens is integrated into the design of an endoscopic optical coherence tomography catheter to achieve near-diffraction-limited imaging free of non-chromatic aberrations, offering high-resolution imaging well beyond the Rayleigh range of the input field.

The authors reveal the complex interplay of factors influencing climate-related body-size changes in tree swallows. Nest warming increased chick size and success yet adult structural size decreased, and mass of males decreased but females did not, the latter linked to reproduction trade-offs.

Hall effect measurement set-up on a single core–shell semiconductor nanowire enables spatially resolved determination of carrier concentration and mobility in the nanowire shell.

Large electronics limit low-noise, non-invasive electrophysiological measurements to a thousand simultaneously recording channels. Here the authors build an array of 65k simultaneously recording and stimulating electrodes and use it to sort and classify single neurons across the entire mouse retina.

Carbon isotopic analysis reveals global biogeographic traits in shark trophic interactions, and sheds light on the diverse foraging behaviour of sharks.

This study characterizes the world’s largest seagrass ecosystem in The Bahamas by integrating spatial estimates with remote sensing and performing extensive ground-truthing of benthic habitat with 2,542 diver surveys, as well as data obtained from instrument-equipped tiger sharks, which have strong fidelity to seagrass ecosystems.

SKP2 is an oncogenic E3-ubiquitin ligase. Here the authors show that SKP2 is epigenetically regulated by the muscle lineage transcription factor MYOD, supports tumorigenesis in the Fusion Negative (FN) subtype of rhabdomyosarcoma (RMS) and impairs differentiation promoting degradation of p57^Kip2.

There is some evidence of a hereditary risk for developing testicular germ cell tumours. Here, the authors use whole-exome sequencing and identify a risk variant for the disease in DNAAF1, a gene involved in microtubule-based cilia.

Idiopathic pulmonary arterial hypertension is a rare and fatal disease with a heterogeneous treatment response. Here the authors show that unsupervised machine learning of whole blood transcriptomes from 359 patients with idiopathic pulmonary arterial hypertension identifies 3 subgroups (endophenotypes) that improve risk stratification and provide new molecular insights.

Most testicular germ-cell tumours are exquisitely sensitive to platinum-based chemotherapies, but little is known about why 10% are resistant. Here, the authors explore the potential underlying mechanisms by probing the genomic landscape of platinum-resistant disease.

The αvβ6 integrin is key in activating the pro-fibrotic cytokine TGFβ in idiopathic pulmonary fibrosis. Here, the authors show an inhaled small molecule αvβ6 inhibitor GSK3008348 induces prolonged inhibition of TGFβ signaling pathways in human and murine models of lung fibrosis via αvβ6 degradation.

It is unclear whether plant trait relationships found at the global scale extend to climatic extremes. Here the authors analyse six major aboveground traits to show that known plant trait relationships extend to the tundra biomes and exhibit the same two dimensions of variation detected at the global scale.

Tumour immune evasion can involve multiple strategies. Here, the authors characterize the immune populations from clinical specimens of lung cancer in conjunction with TCR-β sequencing and show abundant neutrophils affecting cytotoxic T-cell content and the frequent presence of tumour-specific T-cell clones.
