Understanding patterns in woody plant trait relationships and trade-offs is challenging. Here, by applying machine learning and data imputation methods to a global database of georeferenced trait measurements, the authors unravel key relationships in tree functional traits at the global scale.
Here, Wang and colleagues combine short and long sequencing reads to characterize structural variations, prophage and CRISPR spacer elements in human gut microbiomes, and reveal functional differences at a finer level of bacterial strains.
It remains unclear how predictions of future threat affect memory recall, specifically in the case of post-traumatic stress disorder (PTSD). Here, the authors combined computational modeling and brain connectivity analyses to show that individuals with PTSD have exaggerated predictive control and reduced reactive control in a memory suppression task.
This study indicates that approximately 5.8 TW of wind and solar photovoltaic capacity would be required to achieve carbon neutrality in China’s power system by 2050. The electricity supply costs would increase by 19.9% or 9.6 CNY¢/kWh.
Developing classes of substrates for the Nazarov reaction is an important endeavour for synthetic chemistry. Here, the authors report how enyne diketones undergo rhodium-catalyzed metal-organo relay catalysis for the enantioselective construction of chiral allene cyclopentenones via Nazarov cyclisation in good yields and enantioselectivities.
Non-covalent π interactions have been rarely used as a design element for promoting chemical reactions. Here the authors report a Sharpless asymmetric dihydroxylation (SAD)-based kinetic resolution in which a-priori-designed non-covalent forces play a central role in differentiating the enantiomeric substrates.
Covalent organic framework (COF) membranes are important in low energy and cost-effective molecular separations but most COF membranes are assembled via a one-step procedure by concurrent polymerization and crystallization which compromises the ordered structure. Here, the authors propose a two-step phase switching strategy for assembling compact and highly crystalline COF membranes decoupling the polymerization and the crystallization process.
Viral coinfection alongside mycobacterium tuberculosis (Mtb) infection may lead to immune complications or interference with immune responses. Here the authors show that in mice infected with Mtb and LCMV virus the specific TH1 response to MTb is reduced through a type I IFN response to the infecting virus.
Large mechanical loads usually degrade polymers by accelerating fragmentation of their backbones but rarely, they can cause new backbone bonds to form leading to arrested or reversed degradation when new bonds are formed faster than the original bonds break.Here, the authors report the molecular mechanism and analysis of constructive remodeling driven by the macroradical products of mechanochemical fragmentation of a hydrocarbon backbone.
Immunopeptidomics benefits from highly sensitive mass spectrometry (MS). Here, the authors present a computational platform for integrating data-dependent and -independent acquisition MS approaches, and demonstrate its utility for deeper immunopeptidome profiling.
The basalt V-Ti redox proxy indicates that both of the Archean ambient and modified mantle exhibit a ~1.0 log unit increase in their evolution for most cratons, possibly derived by widespread crustal recycling.
Generative models for the novo molecular design attract enormous interest for exploring the chemical space. Here the authors investigate the application of chemical language models to challenging modeling tasks demonstrating their capability of learning complex molecular distributions.
Invariant natural killer T (iNKT) cells are tissue-resident immune cells recognizing lipid antigens. Here the authors find that liver, but not lung nor spleen, iNKT cells alter their transcriptome upon systemic treatment of lipid nanoparticles for the induction of regulatory B cells and suppression of liver and pancreas autoimmunity in mouse models.
Not just differential gene expression but also differential gene regulation in immune cells account for individual differences in the immune response. Authors show here by single-cell RNA-sequencing of peripheral blood mononuclear cells from a large cohort of genetically diverse individuals that gene expression and regulatory changes in these cells depend on the context of and interactions between cell types, genetics, type of pathogen and time after exposure.
Here, via metagenomics and ITS2 sequencing analysis of children's stool samples from three months to four years, the authors show that the fungal composition changes and relative abundance increases at weaning, but unlike bacteria, the overall levels of fungal diversity do not change substantially over time.
