The synthesis of anisotropic nanoparticles with structural diversity and complexity in a rational and systematic fashion is rare. Here, the authors demonstrate a rational and stepwise synthetic strategy for nanoplates with a high degree of intricacy, leading to a gallery of shapes such as rings, triangles, hexagons, and tripods, with tailorable single or double frames.
The Antarctic ozone hole is decreasing in size due to policies implemented following the Montreal Protocol. Here, model simulations show that if recently discovered increase in unreported CFC-11 emissions continue, they could delay the recovery of the ozone hole by well over a decade.
While biologics have been successfully applied in TNF antagonist treatments, there are no clinically approved small molecules that target TNF. Here, the authors discover potent small molecule inhibitors of TNF, elucidate their molecular mechanism, and demonstrate TNF inhibition in vitro and in vivo.
GPCRs are versatile cellular sensors for chemical stimuli but the molecular mechanisms underlying mechanically induced GPCR activation have remained elusive. Here authors identify the C-terminal helix 8 (H8) as the essential structural motif endowing H1R and other GPCRs with mechanosensitivity.
Sintering-resistant Au nanoparticles are highly desirable due to their low Tammann temperature. Here, the authors report an ultrastable titania-supported Au nanocatalyst through an encapsulation strategy under oxidative atmosphere.
Uterine adenomyosis often co-occurs with endometriosis or leiomyoma, but little is known about its molecular underpinnings. Here, the authors show that KRAS mutations are frequent in this disease, which might reduce sensitivity to progestin treatment via epigenetic silencing of the progesterone receptor.
. TGFβ is critical for limiting autoreactive responses of peripheral T cells. Here, the authors show that TGFβ signaling in thymocytes mediates elimination of self-reactive T cells and promotes the expression of self-antigens by medullary thymic epithelial cells.
Atomically thin transition metal dichalcogenides possess a valley degree of freedom, which could enrich the physics underpinning the conventional Nernst effect observed in traditional solids. Here, the authors report experimental evidence of the valley Nernst effect in WSe2 at room temperature.
Enhancers are often transcribed into non-coding RNAs called enhancer RNAs. Here the authors show that super enhancer generated seRNA-1 regulates the expression of nearby myoglobin (Mb) gene by binding to heterogeneous nuclear ribonucleoprotein L during myogenic differentiation.
Recent recession of the Larsen Ice Shelf C has revealed that microbial alteration of illite can occur within marine sediments, a process previously thought to only occur abiotically during low-grade metamorphism. Here, the authors show that such microbial alteration of illite could provide a potential source of Fe release to Southern Ocean waters during Holocene glacial cycles.
Oral microbiota delivery is an approach to treat and prevent disease but suffers from low retention and bioavailability. Here the authors report on a lipid coating to protect against environmental assault maintaining viability and bioactivity of the bacteria and demonstrate effective application in a colitis model.
Existing fibers beneath the world’s oceans can in principle be used as seismic sensors, but the full potential of this possibility has yet to be explored. Here, the authors demonstrate the feasibility of distributed acoustic sensing in a coastal fiber as a sensor for earthquakes and wave phenomena.
Technologies for acquiring explainable features from medical images need further development. Here, the authors report a deep learning based automated acquisition of explainable features from pathology images, and show a higher accuracy of their method as compared to pathologist based diagnosis of prostate cancer recurrence.
Not all mutated cells become malignant, suggesting additional requirements for transformation. Here, the authors track blood progenitors from normal to malignancy driven by MLL-AF9, revealing a subset of myeloid progenitors predisposed to transformation dependent on their normal cycling state.
Susac syndrome is an inflammatory pathology of the brain endothelium. Here the authors show that the pathology is driven by CD8 T cells attacking the endothelium, and that blocking T cell-endothelial adhesion ameliorates the disease in a mouse model, and associates with improved clinical score in 4 patients.
Psychiatric disorders are often accompanied by alterations in BMI and body composition due to changes in eating behaviour and physical activity. Here, Hübel et al. study the genetic overlap between these traits and find that genetic correlations between psychiatric disorders and body composition are sex-specific and evident only in adulthood.
Several factors contribute to the efficiency of protein expression. Here the authors show that the identity of amino acids encoded by codons at position 3–5 significantly impact translation efficiency and protein expression levels.
Early adversity may sensitize people to the effects of later stress, amplifying psychopathology risk. Here, the authors show this stress sensitization effect for adolescents who experienced prolonged institutional deprivation in childhood, but not those assigned to foster care intervention.
Skeletal muscle stem cells express the transcription factor Pax7. Here, the authors isolate, from human muscle, cells that are positive for the endothelial marker CLEC14A and show that despite not expressing pax7, these cells regenerate muscle and contribute to the muscle stem cell niche when transplanted into mice.
The Nd isotope composition of seawater has been used to reconstruct past changes in the various contributions of different water masses to the deep ocean, with the isotope signatures of endmember water masses generally assumed to have been stable during the Quaternary. Here, the authors show that deep water produced in the North Atlantic had a significantly more radiogenic Nd signature during the Last Glacial Maximum compared to today.
