The large low-shear-velocity anomalies in the deep lower mantle below 2300 km depth may relate to H2O-induced ferrous iron stability in bridgmanite, according to laser-heated diamond anvil cell experiments.
Macrophage TP53-induced glycolysis and apoptosis regulator (TIGAR) is implicated in a range of immunopathology. Here the authors show TIGAR drives inflammation and sepsis via activation of TAK1 and that disruption of TIGAR-TAK1 interaction in a murine model of sepsis reduces immunopathology.
Tang et al. describe the development of a fungal genome mining tool which can be used to identify biosynthetic gene clusters from fungal genomes that lack detectable protein domains and demonstrate its functionality.
The mechanisms underlying the zebrafish spinal cord’s impressive innate ability to regenerate after traumatic insults remain largely unknown. Here, the authors show that spinal neurons enact an essential neuron-to-neuron neuroprotective strategy to safeguard cell survival and support the zebrafish’s regeneration process.
Here authors identify the interaction between the SUN-family protein Sad1 and histone H2A-H2B in S. pombe, and reveal the roles of the Sad1-histone interaction in the association of heterochromatin with the nuclear envelope and heterochromatin silencing.
The hierarchy of symmetry breaking in magic-angle twisted bilayer graphene remains a topic of intense fundamental study. Here, the authors determine the spin polarization of symmetry-broken quantum Hall states and Chern insulators in MATBG using a twist-decoupled graphene probe.
OsMAPK6 and CLG1, respectively, target GW6a for phosphorylation and ubiquitylation to favor the substrate stabilization using a different mechanism from prior reports, and the corresponding genetic axes operate non-additively to regulate seed size.
Trace amounts of strong acid can suppress Zn corrosion and promote uniform Zn deposition. Here, the authors use HTFSI to create a hydrophobic micro-environment at the Zn-electrolyte interface, enabling high efficiency and cycling stability.
Singlet oxygen relaxes in water to its triplet ground state. Here, the authors show that heavy-atom tunnelling speeds up this reaction from time scales longer than the age of the universe to microseconds.
The post-resolution phase of inflammation is not simply a linear path towards cessation of immune response but rather a regulated process involving fluctuating immune activity. Here authors show a pivotal role for post-resolution macrophages in driving a wave of T cell recruitment and activation via prostaglandin E2 and α-integrin signalling during the resolution phase of murine pneumococcal pneumonia.
Reliable lithium-ion battery health assessment is vital for safety. Here, authors present a physics-informed neural network for accurate and stable state-of-health estimation, overcoming challenges of varied battery types and usage conditions.
Resonance-based systems such as electroacoustic transducers are often limited by narrow bandwidth. Here, authors report a digital non-Foster inspired circuit demonstrating significant bandwidth and power level enhancement with greater reconfigurability than conventional analog non-Foster approaches.
The first three-dimensional spatial analysis of global marine conservation achievements and fisheries footprint reveals 3D conservation gaps and an underrepresentation of high protection levels across all depths while the 3D footprint of fisheries covers all depths.
Intratumoral heterogeneity has been documented in multiple cancer types, and can be linked to treatment resistance. Here, the authors analyse multiregional samples from colorectal cancers and show gene expression subtypes which are less vulnerable to heterogeneity and may partly contribute to differential patient survival.
Phenotypic changes in exhausted T cells are linked to chromatin remodeling. Here the authors show that pharmacological inhibition of the H3K4me1/2 demethylase LSD1 promotes the persistence and enhances the therapeutic activity of adoptively transferred T cells for cancer therapy.
HSC mutations lead to diverse clonal hematopoiesis outcomes. This study shows how epigenetic traits can predispose clones for dominance. Sox4 increases sensitivity to Tet2 KO, offering insights into variable phenotypes despite identical mutations.
In open-field-line magnetic plasma traps, the attainable cross-field voltage drops are limited by the tolerances of the solid materials of the vacuum vessel. Here, the authors demonstrate the possibility of equilibria that isolate large voltage drops to the interior of the plasma, circumventing this limit.
Natural materials exhibit compelling functionalities owing to their irregular architectures, but the study on irregular architected materials is elusive. Here the authors report a generative computational framework to virtually grow irregular materials with optimized properties that match target stress distributions, facilitating tissue support for orthopedic femur restoration.
It is challenging to design tough structures based on energy absorbing efficiency owing to the difficulties in modeling non-linear deformation. Here, the authors report a human-monitored self-driving lab and discover structural motifs with high energy absorbing efficiencies up to 75.2%.
The chemotherapeutic efficacy of prodrug is limited by its cancer-targeting ability. Here this group reports an engineered commensal Lactobacillus plantarum strain with anticancer prodrugs loading on the surface for nasopharyngeal carcinoma cell-targeting and growth inhibition.
