Rhombohedral-stacked (R-stacked) transition metal dichalcogenide bilayers exhibit remarkable properties, but their large-area epitaxial growth remains challenging. Here, the authors report the remote epitaxy of centimetre-scale single-crystal R-stacked WS2 bilayer films on sapphire substrates.
Lipid biosynthesis in the pathogen M. tuberculosis depends on biotin for posttranslational modification of key enzymes. Here, Qu et al. identify an auxiliary protein that is required by M. tuberculosis to synthesize biotin.
The regeneration of critical-size bone defects, especially those with irregular shapes, remains a clinical challenge. Here, the authors report a shape-memory, tailorable, self-adaptive and bioactive silk fibroin/magnesium composite scaffold that can quickly match irregular defects by simple trimming and lead to good interface integration.
Contact patterns influence the spread of infectious diseases, but mathematical models of epidemics typically only account for age differences in contacts. Here, the authors investigate the importance of other sociodemographic characteristics in shaping contact patterns and vaccine uptake using survey data from Hungary.
The microbiota of the intestinal tract is considered a large biofilm formed by myriads bacteria that have a considerable impact in health and disease. Here, the authors show that biofilm-associated proteins from intestinal microbiota form amyloid-like structures that exacerbate alpha-synuclein pathologies.
Photosynthetic organisms, fungi, and animals contain distinct pathways for vitamin C biosynthesis, but the final biosynthetic step consistently involves an oxidation reaction catalysed by the aldonolactone oxidoreductases. Here, the authors investigate the origin and evolution of the diversified activities and substrate preferences featured by these enzymes using different methods and find evidence that they share a common ancestor.
Standard ways of characterising quantum states incur exponential overhead. Here, the authors consider the task of reconstructing density matrices of multimode continuous variable systems, and demonstrate a method which scales polynomially with the system size, provided the state lies in a polynomial dimensional subspace.
The authors demonstrated an unprecedented level of polarization squeezing of light generated by an atomic ensemble, and a new regime of continuous quantum measurements on a macroscopic material oscillator.
Cell plasticity underlies development and regeneration. Here, the authors show that mouse lung alveolar type 2 cells undergo maturation postnatally and their plasticity is restricted by CEBPA and increases upon viral infection.
Mixed Sn-Pb perovskites have emerged as promising photovoltaic materials for both single- and multi-junction solar cells. Here, authors reveal the thermal degradation mechanism and incorporate carboranes for thermal regulation, resulting in stable all-perovskite tandems with efficiency of over 27%.
How heterogeneously distributed SNARE complexes synchronize fusion pore assemblies during vesicular secretion is unknown. Here, the authors demonstrate a role for SNARE chaperones in coordinating differential release of chemical messengers.
Carbon pricing policies are adopted in many countries around the world to mitigate climate change. This systematic review shows that significant emission reductions of between 5 and 21% are achieved by at least 17 out of 21 reviewed policy schemes.
Here, Murray-Nerger et al use a genome-wide CRISPR/Cas9 screen to show that the nuclear protein SFPQ suppresses lytic reactivation of Epstein-Barr virus by promoting the expression and accumulation of linker histone H1 on the viral genome.
Electrochemical uranium extraction from real nuclear wastewater is appealing but challenging. Herein, Lin et al develop a strategy of ion pair site for enhanced binding of dominant uranium fluoride species in real wastewater, achieving efficient recycling of uranium as powder product.
Head-fixation system is widely used in neuroscience research but has limitations in application due to restraint. Here the authors developed a magnetic voluntary head-fixation system that allows stable rat hippocampal imaging during complex behaviors.
The dorsal raphe nucleus (DRN) is a major source of serotonergic projections to brain-wide targets. Here the authors use optogenetics and fMRI to investigate brain-wide responses to activation of the DRN serotonergic pathway.
Bone marrow stromal cells (BMSCs) are known to promote the development of drug resistance. Here, the authors investigate the chromatin remodeling and associated changes in gene expression in the multiple myeloma (MM) cells following their interactions with BMSCs, which are also observed in extramedullary disease (EMD).
Mice lacking A Disintegrin and Metalloproteinase 9 (ADAM9) do not mount Type 1 interferon responses against encephalomyocarditis infection. Here, Bazzone et al show that ADAM9 regulates innate immune responses via by MDA5.
Atmospheric methane-oxidizing bacteria constitute the sole biological sink for atmospheric methane. Here, Schmider et al. assess the ability and strategies of seven methanotrophic species to grow with air as sole energy, carbon, and nitrogen source, showing that these bacteria can grow on the trace concentrations of methane, carbon monoxide, and hydrogen present in air.
Metals often suffer from reduced strength and ductility after hydrogenation. Here, the authors show hydrogenation can lead to enhancement in strength and ductility accompanied by a large change in magnetic entropy, overcoming the bottlenecks of using amorphous alloys for magnetic refrigerants.
