Four β-N-acetylgalactosaminidase gene families were identified via deep-sea metagenome analysis. The biochemical and structural characterization of the aforementioned enzymes revealed their functional diversity and monophyletic evolutionary history.
Proton conduction is one of the interesting applications of hydrogen-bonded organic frameworks. Here, the authors report hydrogen-bonded organic framework that can be transformed into glassy state, effectively mitigating grain boundary effects, and significantly enhancing proton conduction performance.
Conversation is a primary means of social influence, but its effects on the brain aren’t well-understood. Here, the authors find evidence that people who are central in their social networks facilitate consensus-building conversations that align future brain activity.
Exponential growth of toxigenic Streptococcus pyogenes M1UK lineage accounted for most of the 2022/2023 invasive infection upsurge in the UK. Authors provide evidence that M1UK first emerged in 2008, has genetic evidence of enhanced fitness, and has disseminated to 3 continents.
While machine learning platforms can improve the assessment of Hematoxylin & Eosin (H&E) stained-tumour tissue images, current models typically require manual cell-type annotations in training. Here, the authors develop VOLTA, a self-supervised machine learning framework to improve cell representation learning in H&E images based on the cells environment
Natural killer (NK) cells are assessed for various therapies, but sub-optimal cryopreservation dampens their clinical feasibility. Here the authors show that pretreating human NK cells with IL-15/IL-18 prior to cryopreservation improves NK cell post-thaw viability and functions, potentially via anti-apoptosis gene induction and granzyme B degranulation.
Proline-rich antimicrobial peptides (PrAMPs) inhibit bacterial protein biosynthesis. Here, the authors show that the honey-bee derived PrAMPs Api137 and Api88 inhibit bacterial ribosomes through multiple mechanisms, promising for drug development.
MYC regulates numerous genes involved in cell growth and proliferation. Here, Li-Bao et al. study the DNA regions that regulate Myc transcription in early mouse embryos and pluripotent stem cells. They report a specific region with independent modules dedicated to discrete temporal and spatial phases of Myc expression.
Shadow tomography is efficient for quantum state characterization. Here, the authors implement shadow tomography on photonic states with a single metasurface, which alleviates the complexity in measurement
Whether prediction errors are encoded by synergistic information across the cortex is unknown. Here, the authors demonstrate that distributed representations of prediction errors across the cortex can be highly synergistic.
Wang et al. report large nonvolatile polarization in stretchable polymer ferroelectrics incorporating perovskite nanocrystals. The built-in electric field from poled ferroelectrics stabilises Frenkel defects via interfacial coupling, which can also enhance the polarization of nonferroelectrics.
Conventional material processing methods often suffer by strength-ductility trade-off. Here, the authors show high-pressure and high-temperature treatment can transform an eutectic high entropy alloy to having a hierarchical microstructure with simultaneous enhancements of strength and ductility.
A-to-I editing in animals is catalyzed by enzymes of the Adenosine Deaminase Acting on RNA family, orthologues of which do not exist in fungi. Here, Feng et al. characterise the enzymes involved in A-to-I mRNA editing in Fusarium graminearum.
Assumptions about the use of biomass and CO2 sequestration drive key differences in how emissions from remaining fuels are mitigated in net-zero energy systems, with potentially significant tradeoffs that will need to be evaluated and managed.
It has been previously suggested that STING agonists can improve response to CAR-T therapy. Here the authors report the characterization of the STING agonist IMSA101, showing that STING-induced IL18 secretion enhances CAR-T activity in preclinical cancer models.
Here the authors use on-chip amplitude and phase modulation to synchronously pump a resonator on thin-film lithium niobate for frequency comb generation. They find that pulsed pumping significantly mitigates stimulated Raman scattering and improves the overall efficiency of the device.
Developing stable water oxidation catalysts is of great importance for proton-exchange membrane water electrolyzers. Here the authors report a bicontinuous nanoreactor composed of multiscale defected RuO2 nanocrystals for robust acidic water oxidation reactivity.
