The lowest-energy exciton state in caesium lead halide perovskite nanocrystals is shown to be a bright triplet state, contrary to expectations that lowest-energy excitons should always be dark.
Polarimetric observations of the repeating fast radio burst source FRB 121102 suggest that the bursts may originate from a neutron star in the extreme magneto-ionic environment of an accreting massive black hole or supernova remnant.
A high-throughput assay is used to analyse 40,000 potential extracellular domain interactions of a large family of plant cell surface receptors (LRR-RKs) and provide a cell surface interaction network for these receptors.
In hybrid inviability between Xenopus laevis and Xenopus tropicalis, genomic regions on two X. laevis chromosomes are incompatible with the X. tropicalis cytoplasm and are mis-segregated during mitosis, leading to unbalanced gene expression at the maternal to zygotic transition, followed by cell-autonomous catastrophic embryo death.
Assessment of the impact of armed conflict on large herbivores in Africa between 1946 and 2010 reveals that high conflict frequency is an important predictor of wildlife population declines.
Travel time to cities in 2015 is quantified in a high-resolution global map that will be useful for socio-economic policy design and conservation research.
REV-ERBs, nuclear hormone receptors that regulate transcription as part of the circadian clock cell machinery, inhibit autophagy and lipogenesis in premalignant and malignant cells and impair tumour growth in vivo.
Droplets covered with surfactants that respond to multiple stimuli can assemble into hierarchical assemblies or non-spherical, patchy structures, mimic systems of mechanical gears, and even harbour sequences of chemical reactions.
Asteroseismic ‘sounding’ reveals the internal chemical stratification of the white dwarf KIC08626021, which has a central homogeneous core—composed of 86 per cent oxygen—that has a mass of 0.45 solar masses.
The crystal structure of the full-length glucagon receptor in complex with a glucagon analogue NNC1702 reveals how the peptide ligand interacts with its target and shows the conformational changes required for receptor activation.
An approach is developed for the continuous fabrication of lateral multi-junction heterostructures of transition-metal dichalcogenides, in which the sequential formation of heterojunctions is achieved solely by changing the composition of the reactive gas environment in the presence of water vapour.
Whole-genome sequencing and comparative genomic analysis of immune-related genes of Cercocebus atys and Macaca mulatta identify candidate genes, such as ICAM2 and TLR4, that may explain the AIDS resistance of C. atys.
Noble gases trapped in ice cores are used to show that the mean global ocean temperature increased by 2.6 degrees Celsius over the last glacial transition and is closely correlated with Antarctic temperature.
A 2D topological charge pump in a photonic waveguide array is used to observe boundary physics associated with the 4D quantum Hall effect experimentally.
Heterologous expression of engineered gas vesicles allows noninvasive, deep-tissue ultrasound visualization of engineered bacteria in vivo in mouse tumour models and in the gastrointestinal tract.
The crystal structure of the complement receptor C5aR1 bound to a small-molecule antagonist provides insights into this receptor class and how they could be better targeted therapeutically.
