Switching of nonlinear optical signals is attractive for photoelectronics and photonics, but development is hindered by a lack of control over the switch temperature. Here the authors report a coordination polymer system that serves as an alloy-like nonlinear optical switch with a tunable switch temperature.

Currently the cost of CO₂ chemical fixation remains high because of harsh reaction conditions. Here, the authors report a covalent organic framework screened from 10994 candidates as the efficient CO₂ fixation catalyst under ambient conditions based on the finding of a “pore enrichment effect”.

The authors investigate the optical properties of a heterostructure formed by a metallic substrate and a nanostructured transition metal dichalcogenide multilayer by measuring the reflectance spectrum at different multilayer thicknesses, filling factors and grating periods. The spectra show strong dispersion and avoided crossing of excitons, plasmons and cavity photons along with excitonic mode suppression at the anti-crossing point.

Cycloisomerization of 1,n-allenynes allows to efficiently assembly polycyclic skeletons, however its asymmetric variant remains elusive. Here, the authors report the enantioselective Rh(I)-catalyzed cycloisomerization of 1,6-allenynes and disclose an uncommon 5-exo-dig pathway via DFT calculations.

Organic cocrystals have interesting properties owing to synergistic effects of the individual components but development of effective growth methods for molecular cocrystals is still in its primary stage. Here the authors demonstrate a sublimation method which allows growing organic cocrystals with controlled morphology.

Developing new materials with broadband photoresponse is highly desirable for realizing commercial photodetectors with extended detection ranges. Here, the authors report a cyanide-bridged layer-directed intercalation approach to design viologen compounds with enhanced broadband photoresponse.

Cytokines released after T cell activation improve the efficacy of T cell therapies in mice.

Genomic, transcriptomic and DNA methylation data from tissue samples from 208 Chinese patients with prostate cancer define the landscape of alterations in this population, and comparison with data from Western cohorts suggests that the disease may stratify into different molecular subtypes.

Perivascular and leptomeningeal macrophages, collectively termed here parenchymal border macrophages, are shown to regulate flow dynamics of cerebrospinal fluid, implicating this cell population as new therapeutic targets in neurological diseases such as Alzheimer’s.

Transition metal–ligand fragments are often able to bind and release several carbon monoxide molecules, such as the catalysts used in industrial-scale acetic acid synthesis and the active sites of hydrogenase enzymes, but main-group elements have never shown an ability to bind more than one carbon monoxide molecule; here a boron-based compound stable to moisture and air is synthesized and shown to contain multiple carbon monoxide units bound to the central boron atom.

Studying human-specific de novo genes originated from long non-coding RNA, the authors reveal molecular mechanisms that facilitate nuclear export of these young genes, and show experimental evidence for the role of one such gene in brain development.

Shiro Ikegawa and colleagues report a genome-wide association study for adolescent idiopathic scoliosis (AIS). They identify one locus associated with AIS on chromosome 6q24.1 in Japanese individuals, which was also replicated in individuals of Han Chinese and European ancestry.

The performances of rechargeable batteries are detrimentally affected by low temperatures (e.g., < 0 °C). Here, the authors report a few-layer Bi2Se3 material capable of improving battery cycling performances when operational temperatures are shifted from +25 °C to −20 °C.

Zhong et al. show that the protein GP73 stimulates hepatic glucose production and is induced in response to infection with SARS-CoV-2 in vitro and in vivo, thus proposing a molecular mechanism underlying hyperglycemia associated with COVID-19.

The mechanism by which caffeine, an antagonist of adenosine receptors, regulates metabolism is not clear. Here the authors show that adenosine A₁R receptor expression is increased in the hypothalamus of diet-induced obesity mice, and that body weight can be alleviated by central administration of caffeine via its action on hypothalamic oxytocin neurons.

Obesity is associated with higher breast cancer risk and poor prognosis. Here, the authors show that obesity promotes breast cancer through the recruitment of macrophages with activated NLRC4 inflammasome, which activate IL-1β production, resulting in VEGFA expression in adipocytes and angiogenesis.

Next generation sequencing allows the identification of oncogenic driver genes in pancreatic cancer. Here, in an effort to identify additional causal genes, the authors develop a high throughput in vivoscreen and identify genes that whilst infrequently mutated in pancreatic cancer contribute to tumour formation.

Cancer cells can affect cancer progression by producing systemic effects. Here, the authors show that IGF2 produced by oesophageal cancer cells increases secretion of VEGF from cancer-associated fibroblasts resulting in systemic mobilization of bone marrow-derived cells and increased metastases.

Autophagosome biogenesis depends on the lipid kinase Vps34 and its binding proteins Beclin 1 and Atg14L. Lu et al.identify nuclear receptor binding factor 2 (NRBF2) as a regulator of this complex, and show that loss of NRBF2 impairs autophagy, enhances cell vulnerability to endoplasmic reticulum stress and promotes necrosis in the liver.

The recent plasmid-mediated spread of the mobilized colistin resistance gene mcr-1 poses a significant public health threat, requiring worldwide monitoring and surveillance. Here, Wang et al. compile and analyze a data set of 457 mcr-1-positive sequenced isolates to investigate the origin and global distribution of mcr-1.

An endothelial cell subtype, expressing endomucin and CD31, has been reported to couple angiogenesis with osteogenesis. Here, the authors show that loss of ZEB1 in these cells epigenetically suppresses Notch signaling, leading to impaired angiogenesis and osteogenesis, and that Zeb1 delivery via liposomes ameliorates bone loss in osteoporotic mice
