Ultrasound examination significantly relies on manual operation, which has significant downsides. The authors present UltraBot, a carotid ultrasound robot capable of automated scanning, measurement, and plaque screening, and build an embodied foundation model using deep learning for intelligent, high-precision ultrasound.

Lipase is one of the most important industrial biocatalysts with wide applications, but its catalytic efficiency is often hindered by a closed lid conformation. Here, the authors present an aggregation-induced conformation locking strategy that enables the facile synthesis of highly activated lipase hybrid biocatalysts.

Adenosine-to-inosine editing in SNHG3 (c.1746 A > I) drives non-small cell lung (NSCLC) cancer metastasis and docetaxel resistance by enhancing SSRP1 binding and altering fatty acid metabolism. Targeting this hyper-edited RNA may improve cancer therapy.

Radiative cooling is a sustainable subambient cooling technology. Here, authors show a scalable and practical design of a dual-selective thermal emitter that is shown to have enhanced radiative cooling potential over existing typical designs.

The growth of III–V quantum dot lasers directly onto a silicon substrate aids photonics and electronics integration.

Radiative cooling textiles provide a sustainable means for personal thermal management. Here the nano-textile design realizes an unprecedented combination of human body cooling in both indoor and outdoor conditions without compromising wearability.

An ultrahigh fatigue-resistant AlSi10Mg alloy is achieved by additive manufacturing, with its three-dimensional dual-phase cellular nanostructure acting as a strong volumetric nanocage to inhibit fatigue damage accumulation.

The open-circuit-voltage deficit of cadmium selenide telluride solar cells is typically higher than that of other photovoltaic technologies yet the reasons are unclear. Now, Onno et al. use photoluminescence techniques to break down the contributions of dopants and back contacts to voltage losses.

Here the metabolic transcriptional regulator PGC-1alpha is identified as a component of the circadian clock in mammals, which regulates glucose and lipid homeostasis and energy metabolism. Mice lacking PGC-1alpha in their liver and muscle show abnormal daily rhythms of activity, body temperature and metabolic rate, correlated with the disruption of clock genes.

Resin embedding of specimens is widely used for microscopy but can cause the loss of fluorescence from green-fluorescent protein. Here, the authors show that these proteins can be reactivated in resin-embedded samples through the use of alkaline buffer.

With aging comes a decline in remyelination efficiency, but it is currently unknown why this occurs. In this study, the authors reveal an age-dependent epigenetic mechanism that modulates the levels of oligodendrocyte differentiation inhibitors and dictates the extent of remyelination.

The NADPH oxidase 2 (NOX2) complex is a main reactive oxygen species (ROS) source during inflammation. Here the authors report that NCF4, a subunit of the NOX2 complex, acts a sensor of ROS levels and regulates NLRP3 and AIM2 inflammasome activation, associated with attenuated colorectal cancer progression.

Elevated activity of the methionine cycle is essential for cancer stem cell tumorigenesis and represents a therapeutic vulnerability.

The regulatory networks that govern chromatin accessibility and gene expression in brown and beigeadipocytes remain to be fully elucidated. Here the authors use fat-specific inactivation of BAF60a toreveal a differential role for this chromatin remodeling factor in brown fat thermogenesis and coldinduced browning of inguinal fat.

As opposed to circulating factors that promote energy expenditure, hormones that suppress energy expenditure have remained largely elusive. Here, Wang et al. show that the hepatokine Tsukushi is upregulated in obesity and inhibits sympathetic activity and thermogenesis in fat by promoting whitening.

Integrins are transmembrane proteins that have important roles in cell adhesion and signalling. Here the authors design a therapeutic protein that binds integrin α_vβ₃, has anti-angiogenic activity, and reduces tumour growth in xenograft models, while being seemingly well tolerated.

The LXR-SREBP1c pathway promotes hepatic lipogenesis that is deregualted in fatty liver disease. Here the authors show that the long noncoding RNA Blnc1 contributes to the development of obesity-driven steatosis by enabling SREBP1c trascriptional activity in response to LXR activation.

Tetrathiomolybdate (TM) and Cu-ATPases, e.g. Wilson (WLN) protein, affect the efficacy of common anticancer drug cisplatin. Here, the authors show that TM generates a protein dimer with a WLN domain by expelling copper and provide insight into the synergy of TM and cisplatin in cancer chemotherapy.

Fuel cells are promising for sustainable energy generation, but are limited by the performance of electrocatalysts. Here the authors synthesize dendritic palladium–copper–cobalt nanoalloys with electrocatalytic activity for oxygen reduction and formic acid oxidation as well as alcohol tolerance.

The brown fat-derived neuregulin 4 regulates hepatic lipid homeostasis and whole-body insulin sensitivity

The Digital Brain platform is capable of simulating spiking neuronal networks at the neuronal scale of the human brain. The platform is used to reproduce blood-oxygen-level-dependent signals in both the resting state and action, thereby predicting the visual evaluation scores.

The authors detect cytosolic histone deacetylase-1 (HDAC1), a nuclear transcriptional repressor, in damaged axons in brains of humans with multiple sclerosis and of mice with cuprizone-induced demyelination. They show a cytotoxic mechanism in which the exported HDAC1 impairs mitochondrial transport, independent of its nuclear function.

The structure of nanoparticles strongly influences their properties. Here, the authors use single crystal X-ray diffraction to resolve the crystal structures of Ag₁₃₆ and Ag₃₇₄nanoparticles, enabling the observation of local structure distortion and the lower size limit of surface plasmon resonance.

Guanylate-binding proteins (GBP) have a function in inflammasome formation and pathogen defence. Here the authors show that these GBP proteins are able to kill certain bacteria and promote selective inflammasome activation and that this is mediated by specific GBP protein regions.

The first topological Dirac-vortex microcavity lasers on silicon are experimentally realized. Operating under room-temperature continuous-wave conditions, these lasers mark an important step toward integrating topological lasers with CMOS-compatible optoelectronic systems.

It has been thought that a switch by the muscle from oxidative phosphorylation to glycolysis is associated with the development of insulin resistance. Jiandie Lin and colleagues now show that transgenic mice that undergo this switch, due to modest overexpression of Baf60c, are actually more glucose tolerant and insulin sensitive compared to wild-type mice when both are placed on a high-fat diet, suggesting the switch is actually an adaptive process.
