A meta-analysis of genome-wide association studies of type 2 diabetes (T2D) identifies more than 600 T2D-associated loci; integrating physiological trait and single-cell chromatin accessibility data at these loci sheds light on heterogeneity within the T2D phenotype.

Genome-wide association and fine-mapping analyses in ancestrally diverse populations implicate candidate causal genes and mechanisms underlying type 2 diabetes. Trans-ancestry genetic risk scores enhance transferability across populations.

This report from the 1000 Genomes Project describes the genomes of 1,092 individuals from 14 human populations, providing a resource for common and low-frequency variant analysis in individuals from diverse populations; hundreds of rare non-coding variants at conserved sites, such as motif-disrupting changes in transcription-factor-binding sites, can be found in each individual.

A trans-ancestry meta-analysis of GWAS of glycemic traits in up to 281,416 individuals identifies 99 novel loci, of which one quarter was found due to the multi-ancestry approach, which also improves fine-mapping of credible variant sets.

The goal of the 1000 Genomes Project is to provide in-depth information on variation in human genome sequences. In the pilot phase reported here, different strategies for genome-wide sequencing, using high-throughput sequencing platforms, were developed and compared. The resulting data set includes more than 95% of the currently accessible variants found in any individual, and can be used to inform association and functional studies.

Myocardial infarction treatment strategies remain challenged in effectiveness. Here we present a bioelectronic interface capable of producing on-demand abundant bioactive extracellular vesicles near the disease area for in situ localized treatment.

Nano-masking of the surface of tumour-derived extracellular vesicles blocks their immune-evasive action. This improves their phagocytosis by dendritic cells, leading to maturation of T-cell action and culminating in undampened anti-tumour immunity.

Both rare and common variants contribute to the aetiology of complex traits such as type 2 diabetes (T2D). Here, the authors examine the effect of coding variation on glycaemic traits and T2D, and identify low-frequency variation in GLP1Rsignificantly associated with these traits.

Rapid hemostasis of deep noncompressible irregularly shaped trauma wounds is challenging. Here the authors report a neutrophil extracellular traps (NETs)-inspired DNA hydrogel that is able to induce NETs-like thrombosis as a physical blockade and biological clot to arrest bleeding in deep tissues.

Pathogenic gut microbiota is responsible for a few debilitating gastrointestinal Diseases. Here, the authors develop a wireless mechanoelectronic device designed to manufacture of functional vesicles in vivo to regulate microbiome.

This study reports endothelial leakiness in vitro, in silico and in vivo, where adherens junctions are disrupted by their exposure to the anionic oligomers and seeds of Alzheimer’s amyloid beta, preceding proinflammatory and pro-oxidative events.

Nanoparticle penetration into tumours is an obstacle to cancer therapeutics. Here the authors show that the tumour vascular basement membrane constitutes a barrier that reduces nanoparticle delivery and demonstrate an immune-driven strategy to overcome the barrier, increasing nanoparticle movement into tumours.

Nanoparticles used in nanomedicine can induce increased vascular leakiness and therefore accelerate intravasation and extravasation of cancer cells, exacerbating existing metastasis and promoting the appearance of new metastatic sites.

Traditional nanomedicine relies on tumor induced EPR effect for drug delivery. Here the authors show that gold nanoparticles are independently able to induce leakiness at tumor vasculature to enhance the tumor killing effect.

In this study, the authors report that anionic nanoplastics can harness the paracellular space of endothelial cells and puncture blood vasculature ex vivo and in vivo, thereby entailing new environmental and health implications.

Chirality transfer from molecules to nanomaterials enables advanced optical functionalities. Here, the authors use exfoliated MoS₂ nanosheets to seed the growth of chiral Au nanoparticles to form Au/MoS₂ heterostructures for enantioselective drug release.

Understanding the fundamental nano–bio interactions of nanomaterials intended for biomedical use might unlock potential alternative applications. Here the authors reveal a tumoricidal mechanism of black phosphorus nanomaterials where these nanomaterials directly affect the mitotic centrosome machinery by suppressing polo-like kinase 1, suggesting that nanomaterials can be applied in targeted cancer therapy with their intrinsic nano–bio properties.

1000 Genomes imputation can increase the power of genome-wide association studies to detect genetic variants associated with human traits and diseases. Here, the authors develop a method to integrate and analyse low-coverage sequence data and SNP array data, and show that it improves imputation performance.

Transition metal dichalcogenide (TMD) quantum dots (QDs) have promising electronic properties which might be further tailorable by defect engineering. Here the authors describe a room temperature aqueous based synthesis of TMD QDs with controlled defect concentration, and demonstrate the correlation between defect concentration and biomedical activity.

Synthetic nanochemistry currently lacks the molecular step-by-step routes afforded to organic chemistry by total synthesis. Here, the authors track the seeded growth of atom-precise gold nanoclusters using mass spectrometry, revealing that the clusters evolve through a series of intermediates in two-electron steps.

This paper reports a facile cyclic reduction–decomposition method for the aqueous-based synthesis of highly luminescent Ag nanoclusters (NCs) with tunable emissions. A reduction–decomposition–reduction cycle was used to modify the non-luminescent Ag NC intermediates with improved stability against subsequent etching by thiol ligands, which created a mild size-/structure-focusing (or etching) environment and produced highly luminescent Ag NCs with intense red (Ag₁₆(SG)₉) and green (Ag₉(SG)₆) emission. The highly luminescent Ag NCs also possessed superior antimicrobial properties against the multidrug-resistant bacteria Pseudomonas aeruginosa via generating a high concentration of intracellular reactive oxygen species.

Four oligonucleotide strands are hybridized to form the 3D DNA nano-pyramid. Three thiol groups-terminated vertex can immobilize the pyramid firmly onto the surface of gold electrode, while the remaining non-thiolated vertex at the top with carboxyl group allows the covalent binding of anti-IgG antibody. Through traditional sandwich immunoreaction, the electroactive tag, ferrocene (FeC) generates electrochemical signals used to detect the analyte IgG. The pyramidal structure with higher rigidity encourages more uniform surface assembly and less steric effect, resulting in lower background interference. The pyramid's hollow structure further contributes to efficient electron transfer and makes this immunoassay system achieve an ultrasensitive detection limit.

While traditional farming has fed billions of people, it is exerting mounting pressure on land, water and the environment. To complement current agricultural practices, we present a green chemical farming concept that provides pathways to efficient and renewable food production by leveraging chemistry and chemical engineering.

In this work, an anticancer drug, metformin, has been used to promote DNA single strands to assemble into well-defined DNA nanostructures. The resulting metformin-DNA complex nanostructures can simultaneously deliver metformin and KRAS siRNA to synergistically treat KRAS-mutated, non-small cell lung cancer in vivo.
