Exploitation of noncovalent interactions has received much attention for the design of metal catalysts. However, because of the weak nature, CH-π interactions have been less utilized for the control of organic reactions. Here, the authors report that the CH-π interaction can be used to kinetically accelerate catalytic C-H activation of arenes.
Here, the authors fabricate a metasurface with nanometre-sized plasmonic hotspots that interact coherently with WS2 excitons, achieving ultrastrong exciton-plasmon coupling.
Multiple autocatalytic reactions producing thiols are known, but negative feedback loop motifs are unavailable for thiol chemistry. Here, the authors develop a negative feedback loop based on the selenocarbonates, in which thiols induce the release of aromatic selenols that catalyze the oxidation of thiols by organic peroxides.
The problem of reversibility within general quantum resource theories is still an open one. Here, the authors prove that a reversible entanglement manipulation framework (and, consequently, the concept of entanglement entropy) can be formally established by adjusting the setting to allow for probabilistic operations
HIV exposed but uninfected infants may face an increased risk of serious infection and mortality. In this work, the authors utilise a cohort from rural Zimbabwe to explore the biological mechanisms underlying infant mortality.
Phase diagrams of materials are typically based on a static order parameter, but it faces challenges when distinguishing subtle phase changes, such as re-ordering. Here the authors introduce a dynamic re-order parameter, in particular magnons, and illustrate it in a material with complex magnetic phases.
Perception plays a pivotal role in advancing future intelligent textiles. Here, the authors develop smart perceptual textiles using natural-derived ionic-conductive silk fibers. These textiles can electrically detect external hazards and precisely pinpointing human touch, making them suitable for smart protective clothing and soft human-machine interfaces.
Methanogens conserve energy through methane generation, however the biochemical details of anaerobic respiration in methanogens remain unclear. Here, authors show a multiheme c-type cytochrome, MmcA, plays a critical role in methanogenesis and anaerobic respiration.
Inducible gene expression systems can be used to control the expression of a gene of interest by means of small molecules. Here the authors present CASwitch, a synthetic gene circuit platform enhancing inducible gene expression systems by reducing leakiness and boosting fold induction, for real world applications like gene therapy vector production and biosensors.
Macroglia are neural cells that have garnered less interest than neurons despite their crucial functions including neurogenesis. Here the authors use sequencing from several species to investigate the evolution of macroglia and of adult neurogenesis.
The spatial mapping of proteins can give important functional insights. Here, Zhu et al. develop a cross-linking mass spectrometry-based spatial proteomics method that does not require protein engineering, affords sub-organelle resolution, and elucidates both protein locations and membrane topologies.
Asian soybean rust (ASR) is a devastating disease of soybean. Here, the author report the identification of an atypical pair of nucleotide-binding leucine-rich repeat (NLR) encoding genes and how they function together to confer broad-spectrum resistance to ASR.
Cruz et al. describe the role of Dbp10/DDX54 in remodeling rRNA structure within the immature eukaryotic peptidyl transferase center of the ribosome, coupling energy-dependent catalysis to a post-catalytic role in factor exchange during 60S ribosomal subunit assembly.
Prompt physiological reactivation after rainfall pulses may be key for microbial survival in arid ecosystems. Here, the authors use stable isotope tracers, single-cell NanoSIMS and metatranscriptomics to shed light on how desert biocrust microbial communities respond to rewetting.
Breastfeeding confers lifelong benefits to both mother and child, yet women worldwide experience lactation insufficiency. Here, the authors show that DNA damage occurring in the breast during pregnancy drives the generation of milk-producing cells.
This article presents a unique nanocomposite plasmonic-excitonic glass with extraordinary amplified optical properties: ultra-narrow photoluminescence (FWHM = 13 nm) and ultrashort photoluminescence lifetime (90 ps) at room temperature
Childhood malnutrition in Africa is a glaring example of global inequality, and mortality remains high. Here, the authors report the results of the TAME randomized phase II clinical trial, in which intestinal healing was the target of four potential interventions in malnourished children in Zambia and Zimbabwe.
Grasses share a whole-genome duplication called rho, but the adaptive implications are unclear. Here, the authors conduct phylogenomic and phylotranscriptomic analyses of 363 grasses, identifying additional whole-genome duplications and finding that duplicates are implicated in environmental adaptations or morphogenesis.
