Nanoscale circularly polarized light sources are an important building block for future integrated photonics. Here the authors demonstrate circularly polarized light emission from a thin organic single crystal light-emitting diode.
Impacts of Tibetan Plateau darkening remain unclear. Here authors show that darkening under the RCP8.5 scenario will increase South Asian monsoon precipitation and the “South Flood-North Drought” pattern over East Asia, while lead to local glacier loss.
Authors carry out a systematic review and meta-analysis to evaluate the performance of fibrosis biomarkers for the diagnosis of fibrosis and cirrhosis in patients with chronic hepatitis B virus infection living in sub-Saharan Africa.
Self-assembled nanocomposites present opportunities for a range of phase morphologies and desirable properties. Here authors present tuneable self-assembled nanostructures in the SnO2:NiO system; the double-percolated system expands the design of self-assembled oxides for practical applications, e.g. in optoelectronics.
Heteroepitaxy on colloidal nanocrystals often yields defective heterostructures due to intricate reaction pathways. Here, the authors decode the surface chemistry at the molecular level to realise defect-free interfaces with atomic uniformity.
Deep level transient spectroscopy (DLTS) is an established characterization technique used to study electrically active defects in 3D semiconductors. Here, the authors show that DLTS can also be applied to monolayer semiconductors, enabling in-situ characterization of the energy states of different defects and their interactions.
Enhanced IL-1β signaling pathway causes hematopoietic stem cell (HSC) to differentiate into myeloid cells and contributes to malignant hematopoiesis. Here the authors reveal that HSC differentiation is controlled by balanced levels of IL-1 receptor antagonist (IL-1rn) and IL-1β under steady-state, and that IL-1rn protects against pre-leukemic myelopoiesis by repressing IL-1β signaling.
The mammalian mitochondrial genome contains two noncanonical stop codons, AGA and AGG. Here, the authors show that mtRF1, a mitochondrial protein of unknown function, triggers translation termination at AGA or AGG, placing mtRF1 among mitochondrial translation factors.
GABAB receptors mediate the effects of the main inhibitory neurotransmitter in the brain. Here, authors identify the cytoskeletal protein filamin A as a key player that controls the exact location and function of GABAB receptors at the cell surface.
Despite their vast potential, the practical deployment of MXenes has been hampered by their tendency to be oxidized. Here, the authors show that simply vibrating MXene films in just a minute can remove the oxide layer formed and restore their electrochemical performance close to its original state.
The covid pandemic has highlighted the need for rapid antibody development. Here, authors develop an approach called SLISY, which uses NGS with phage display to simultaneously assess millions of clones to rapidly isolate specific antibodies against SARS-CoV-2 and its evolving variants.
The effect of sequence polymorphisms on recombination is not fully understood. Here, the authors develop the seed-typing method to map crossovers (COs) by sequencing and show that COs occur preferentially within polymorphic hotspots and that this effect depends on the mismatch repair gene MSH2 in Arabidopsis.
TRPV1 as a drug target suffers from side effects of hypothermia. Here, authors engineer a peptide, sRhTx, as a positive allosteric modulator of TRPV1 channel. It potentiates the activity of TRPV1 to reversibly ablate pain-sensing nerve terminals for long-lasting analgesia without changing mice body temperature.
Tactile sensors in human-machine interaction systems can provide precise input signals and the necessary feedback between humans and machines. Here, the authors developed a black phosphorous-based tactile sensor array system that can provide touch into audio feedback.
Mercury (Hg) concentrations and isotopes from terrestrial sections of southern Pangea provide evidence of the global volcanic effects of the Siberian Traps during the Permian-Triassic transition
How molecular diversity in neurons links to versatile functions is elusive. Here the authors profiled embryonic spinal motor neurons with single-cell RNAseq and identified molecular subtypes targeting distinct muscle groups in different species.
The biologically productive eastern boundary upwelling systems (EBUSs) are regarded as thermal refugia in a warming climate. However, the authors here show that Southern Hemisphere EBUSs are likely to become hotspots of future marine heatwaves.
The mitochondrial ATP synthase produces the bulk of cellular ATP. Here, the authors report a function of the mitochondrial Hsp70 in the formation of the catalytical head and in its assembly with the peripheral stalk to form the mature ATP synthase.
Coastal ecosystems are promoted as nature-based solutions to climate change. Here, the authors show that natural methane emissions across a variety of vegetated and unvegetated coastal habitats can, however, offset one-third of the carbon sink capacity attributed to atmospheric carbon dioxide uptake.
Sodium ion storage remains relatively unexplored in comparison with well-understood lithium ion storage mechanisms. Here, the authors systematically investigate the surface-redox sodium ion storage properties of anatase titanium dioxide, which delivers excellent rate capability, cycling stability and low overpotentials.
