Soil organisms are affected by the presence of predatory protists. Here, the authors predatory protists are negatively associated with bacteria wilt disease incidence in tomato plants and that fertilisation enhances the abundance of predatory protists
It is unclear whether naturally evolved de novo proteins have stable, folded structures. Here, through systematic identification and structural modeling of de novo genes, this study reveals that a small subset of these proteins may have well-folded structures, and were likely born with these structures.
Caloric restriction (CR) has been demonstrated to have a role in tumour growth and therapy response but its effects on cancer stem cells are less known. Here, in Acute Promyelocytic Leukemia, the authors show that despite initial anti-tumour effect, CR drives the selection of leukaemia-initiating cells resulting in relapse which could be prevented by ablation of LSD1.
Increasing rainfall intensity produces opposite hydrological effects across a large river basin in South China (drying in the uplands vs. wetting in the lowlands) due to spatially contrasting interactions between rainfall intensification and topography.
Nutrient limitation is a well-known control of phytoplankton growth, but predicting specific responses in individual lakes based on nutrient data alone has proven challenging. Here, the authors show that long-term signals of chlorophyll-a dynamics in shallow lakes can be captured based on stoichiometric effects of N and P concentrations along a continuum of total N:total P ratios.
Inspired by insects in nature, the authors develop a neuromorphic robotic system with obstacle avoidance, tunnel centering and gap crossing capabilities. Their robotic system accomplishes these multiple capabilities by steering towards regions of low apparent motion.
Whether Kupffer cells play a role in regulating the pathogenesis of fatty liver disease remains to be completely explored. Here, the authors show GPR3 activation stimulates glycolysis in Kupffer cells through GPR3-β-arrestin2-GAPDHPKM2 pathway and inhibits high-fat diet induced obesity and liver pathogenesis.
In this work, the authors report the full-length structure of the attachment glycoprotein from Langya Henipavirus, which could enhance the understanding of emerging Henipavirus and provide important clues for vaccine development in the future.
Challenges in reproducibility and large-scale expansion limit the current applicability of human intestinal organoids. Here, the authors present a feeder-free, chemically-defined culture method for enrichment of intestinal stem cells isolated from 3D human intestinal organoids.
Li–CO2 batteries following Li2CO3-product route suffers from low output voltage and severe parasitic reactions. Here, the authors introduce a copper-based solid redox mediator in Li–CO2 batteries with an efficient Li2C2O4 product route to circumvent the shuttle effect and sluggish kinetics caused by soluble mediators.
Plant antagonists may disrupt the allocation of carbon resources from plants to mutualistic microorganisms. Here, the authors report how plants attacked by cyst nematodes and aphids maintain carbon transfer to arbuscular mycorrhizal fungi through fatty acid transfer whilst the limiting the loss of sugars.
Different approaches have been described for the transdermal delivery of drugs. Here the authors report the design of a fluorocarbon modified chitosan-based non-invasive transdermal platform for the delivery of biomacromolecules, such as viral antigens for vaccines or immune checkpoint inhibitors for melanoma immunotherapy.
The cellular origin of human pancreatic ductal adenocarcinoma (PDAC) is still unclear. Here the authors used human primary acinar and ductal cells to successfully reconstitute PDAC tumorigenesis from both lineages and revealed transcriptional changes during early PDAC progression.
Lightweight flexible piezoelectric polymers are demanded for various applications, but restricted by the low instinctively piezoelectric coefficient and complex poling process. Here, the authors develop a high performance lightweight, flexible self-poled piezoelectric polymer composite towards sustainable self-powered sensing and energy harvesting.
The optical properties of nanoalloys are complex and difficult to describe. Here, the authors use density functional and Mie theory to calculate the extinction of Au-Co and other nanoalloys of interest for quantum optics, magnetooptics, catalysis, and metamaterials.
scRNA-Seq has enabled the study of dynamic systems such as response to a drug at the individual cell and gene levels. Here the authors introduce a framework to interpret differences at the trajectory, cell populations, and individual gene levels.
Eosinophils are innate immune cells critical for protection from parasites, but their developmental origin remains under studied. Here they analyze development of eosinophils in zebrafish and find that eosinophilic lineage commitment and differentiation are regulated by the Cebp1-Cebpβ axis.
Most multi-degrees-of-freedom systems are composed of several piezoelectric stacks, leading to cumbersome and complicated structures. Here, the authors propose a piezo metasurface to achieve various types of high strains in a wide frequency range.
The synthesis of three-dimensional (3D) covalent organic frameworks (COFs) with highly connected building blocks presents a significant challenge. Here, the authors report the synthesis of two 3D COFs with the nia topology, by introducing planar hexagonal and triangular prism nodes.
Here the authors demonstrate that cropland expansion following the historical trend together with closing the current exploitable yield gap by half or more across Africa reduces the continent’s reliance on land conversions and imports by 2050.
