NLRP3 inflammasome activation is regulated by various signaling pathways to ensure inflammation does not go unchecked. Here the authors show how deubiquitination avoids this regulation to activate the NLRP3 inflammasome through the function of UAF1/USP deubiquitinase complexes.
China has enacted Electric Heating Policy to substitute electricity for in-home combustion for rural residential heating. Here the authors show that this shift would greatly increase national carbon emissions by 101.69–162.89 megatons in 2015 while impeding China’s carbon mitigation process in the future.
Previously it was shown that an N-terminal tau fragment (NT1) measured in plasma can differentiate individuals with Alzheimer’s disease from healthy controls. Here the authors show that plasma levels of NT1 can associate with future cognitive decline in cognitively normal elderly individuals.
Senescence is a state of stable proliferative arrest. Here, the authors perform Hi-C analysis on oncogenic RAS-induced senescence in human fibroblasts and characterize the changes in the 3D genome folding associated with the senescence-specific gene expression profile, which are mediated in part through cohesin redistribution on chromatin.
The tumour microenvironment (TME) has a major role in chemoresistance in multiple myeloma. The authors show that a nanoparticle targeted to TME and loaded with bortezomib (BTZ) and Y27632 is more effective than free drugs, non-targeted and single-agent controls and reduces BTZ-related side effects.
Delay eyeblink conditioning depends on the simplex lobule-interposed nucleus pathway in the cerebellum. Here, the authors show that the vermis-fastigial nucleus-medullary reticular nucleus pathway modulates the conditioned and unconditioned eyelid closure during delay eyeblink conditioning.
The Y complex is an essential component of the nuclear pore complex but a full model based on experimental structures is lacking. Here, the authors complete the model of the yeast Y complex with two nanobody-bound crystal structures, providing molecular insights into its flexibility and membrane anchoring.
Thermal metamaterials are able to produce unconventional physical properties. Here, the authors demonstrate a thermal metamaterial with conductivity that can be continuously tuned over a very large range.
Removal of integrated HIV DNA remains a roadblock for HIV cure. Here, Mancuso et al. show that intravenous administration of an adeno-associated virus-based CRISPR/Cas9 gene editing construct to SIV-infected macaques results in excision of integrated proviral DNA from infected blood cells and tissues known to be viral reservoirs.
The authors have previously reported split-GFP-based contact site sensors (SPLICS) to document endoplasmic reticulum/mitochondria contact sites. Here they extend this work and develop a range of improved SPLICS sensors to detect single and multiple organelle contact sites at different distances.
Environmental and dietary factors are known to play a role in the development of coronary heart disease. Here the authors apply a genomic-inspired methodology to Nurses’ Health Study data to explore comprehensively and agnostically the association of 257 nutrients and 117 foods with coronary heart disease risk.
Whether or not diversity begets stability in ecological networks could depend on the spatial dispersal dynamics of species. Here the authors use mathematical models based on Turing pattern formation to show that trophic interactions combined with dispersal can destabilize complex ecosystems.
The SARS-CoV-2 viral genome is encapsulated by the nucleocapsid protein (NSARS-CoV-2) that is essential for viral replication. Here, the authors show that RNA induces liquid-liquid phase separation of NSARS-CoV-2 and how NSARS-CoV-2 phosphorylation modulates RNA-binding and phase separation and that these RNA/NSARS-CoV-2-droplets recruit and concentrate the SARS-CoV-2 RNA-dependent RNA polymerase complex in vitro, which would enable high initiation and elongation rates during viral transcription.
Antarctic krill are known to be important to the carbon cycle, but the exact contribution is not known. Here the authors show that krill moulting is a major vector of carbon export in the Southern Ocean, together with krill faecal pellets accounting for almost 90% of annual particulate organic carbon flux.
Myo-Inositol phosphates (InsPs) and pyrophosphates (PP-InsPs) are important second messengers but their analysis remains challenging. Here, the authors develop a capillary electrophoresis-mass spectrometry method for the identification and quantitation of InsP and PP-InsP isomers in cells and tissues.
Predicting cancer risk requires large datasets and sophisticated models. Here the authors integrate polygenic risk scores and modifiable risk factors for multiple cancers in the UK Biobank, improving general risk prediction and distinguishing cases where genetic or lifestyle factors have stronger associations.
The maintenance of ecological diversity depends on the strength and direction of competitive interactions, but these interactions are difficult to study in microbial communities. Here the authors use engineered E. coli strains to show that competitively weak strains can persist when pairwise interactions are asymmetrical.
During SARS-CoV-2 replication subgenomic RNAs (sgRNA) are transcribed and subsequently translated into viral proteins. Here, Alexandersen et al. provide evidence that sgRNA is not necessarily an indicator for active viral replication, but can be detected up to 17 days after symptom onset in clinical samples.
