Nod factor signaling, and nitrate distinctly affect Lotus japonicus root exudate, microbiome composition and connectivity, emphasizing the role of signaling between plant and distinct members of soil microbiota in shaping the overall assemblies.
H2O2 stress is known to activate a slew of transcription factors that restore redox balance. Here, the authors use live-cell imaging and single-cell analysis to reveal that the transcription factors that are activated and their timing of activation is dose dependent.
Xiao et al. uncover a strong linkage between marine bacterial tetraether lipids and benthic oxygen uptake in deepsea trench regions, indicating their potential for assessing microbial diagenetic activity and organic carbon degradation.
Pulse tube refrigerators are a critical enabling technology for many disciplines that require low temperatures, including quantum computing. Here, the authors show that dynamically optimizing the acoustic parameters of the refrigerator can improve conventional cooldown speeds up to 3.5 times.
Measuring quantum entanglement remains a demanding task. The authors introduce two functions to quantify entanglement induced by fermionic or bosonic statistics, in transport experiments. Both functions, in theory and experiment, are remarkably resilient against the nonuniversal effects of interactions.
Targeting oncogenic ALK activity in neuroblastoma is an attractive therapeutic strategy but success has been limited by resistance to ALK inhibitors. Here, the authors identify loss of miR-1304-5p as a driver of ALK inhibitor resistance via regulation of NRAS, and therapeutically target this axis with the addition of a farnesyltransferase inhibitor in preclinical models of neuroblastoma.
Notwithstanding their success as strongly σ-donating and π-accepting ligands, to date no chelating bis[cyclic (alkyl)(amino)carbenes] have been reported. Here the authors describe a chelating, C2-symmetric bis[cyclic (alkyl)(amino)carbene] ligand, as well as its pseudotetrahedral complexes with iron, cobalt, nickel, and zinc dihalides.
There is a desire to know how the threefold ferrielectric coexists with the antiferroelectric phase. Here, the authors realize a threefold-modulated ferrielectric phase regulated by strain-mediated phase separation in PbZrO3 thin film.
Challenges including hypoxia, inflammation, and inadequate exosome intracellular delivery hinder wound healing. Here, the authors show that a multifunctional exosome-coated oxygen nanobubble-laden hydrogel enhances exosome delivery and mitigates hypoxia for enhanced wound healing.
Inspired by the alternating chirality backbone pattern of some effective peptide antimicrobials, here authors design lysine-rich heterochiral peptides that show antimicrobial activity.
This study identifies temporal and coordinately regulated cell-state-specific super-enhancers driving the expression of transcription factors that control circuits needed to switch neuroblastoma tumor cells from self-renewal to differentiation.
Using ice sheet model and glacio-isostatic adjustment model simulations and paleoclimate proxies, this work demonstrates that the most likely cause of past West Antarctic grounding-line reversal was a regime shift from a warm to cold ocean cavity.
The neural mechanisms underpinning visual illusions remains poorly understood. Here, the authors recorded the neural responses of mouse primary visual cortex to illusory grating and found delayed responses to illusory brightness, showing that optogenetic inhibition of higher visual areas reduced V1 response to illusions but not to real gratings.
Little is known about the genetic basis of the rhythmic component of bird song, an important trait in sexual selection and species recognition. By studying a system with innate vocalizations, the Pogoniulus tinkerbirds, this study finds candidate genes that underlie differences in speed in vocal rhythm in this system.
Here, by applying evolutionary genomics approaches to metagenomics data of lake microbiomes, the authors reveal that freshwater species with small genomes face extended periods with their niche adaptation capabilities frozen.
Integrating self-healing capabilities into skin-like stretchable transistors presents a persistent challenge. Here, by using a supramolecular polymer matrix, the authors develop autonomous self-healing transistors and skin-like logic circuits.
Sakuranetin is an important phytoalexin. The authors find that sakuranetin in rice attenuates endocytosis of effectors from the fungus Magnaporthe oryzae and enhances resistance against rice blast.
Here, using murine models of prostate cancer, the authors show that reduced fecal microbiota alpha-diversity correlates with increased prostate tumor burden, and that Omega-3 prebiotic supplementation reduces prostate cancer up-grading associated with a reduction of gut Ruminococcaceae and fecal butyrate levels.
Crystalline materials’ properties are highly dependent on their size. Here authors report a general synthesis of ultrasmall (4–6 nm) and highly defective Zr/Hf-Metal Organic Frameworks nanoparticles that present enhanced peptide hydrolysis performance.
