High-resolution X-ray imaging requires a high radiation dose. Here, the authors achieve low-dose 3D imaging by increasing the XEPL intensity using a double-shell nanostructure with two heterogeneous interfaces.
GPR34 is a GPCR which has an immunomodulatory role and recognizes lysophosphatidylserine (LysoPS) as a putative endogenous ligand. Here, authors report two cryo-EM structures of human GPR34-Gi complex with one of two ligands bound: either the LysoPS analogue S3E-LysoPS, or its derivative M1.
This study shows that trees are likely to change clouds in the future and reveals that climate models struggle to accurately represent the relevant processes of aerosol-cloud-climate interactions over forests.
Site-specific recombinases such as the Cre-LoxP system are routinely used for genome engineering in both prokaryotes and eukaryotes. Here the authors develop 63 symmetrical LoxP variants and test 1192 pairwise combinations to determine their cross-reactivity and specificity upon Cre activation.
2D vertical transport transistors (VTFETs) may promote the downscaling of electronic devices, but their performance is usually restricted by the thermionic limit. Here, the authors report the realization of short-channel steep-slope VTFETs based on MoS2/MoTe2 heterojunctions integrated with resistance threshold switching cells.
Transcriptional regulator MtrR inhibits the expression of the multidrug efflux pump operon mtrCDE in Neisseria gonorrhoeae. Here, Hooks et al. show that hormonal steroids bind to MtrR and decrease its affinity for cognate promoters, thus leading to increased mtrCDE expression and enhanced antimicrobial resistance.
Blue phosphorene (BlueP) is a 2D phosphorus allotrope predicted to host Dirac fermions and other interesting electronic properties. Here, the authors report the growth of large-area BlueP films with ordered chiral nanostructures on Cu(111) substrates, expanding the range of its potential applications.
Do proteasomes catalyze peptide splicing? Here, the authors develop and apply a method to identify spliced peptides produced from entire proteins, confirm that proteasomes produce a sizeable variety of cis-spliced peptides with well-defined characteristics, and show that non-spliced and spliced peptides are concentrated in hotspots.
Seed dormancy is the preferred trait in rice production as it can prevent preharvest sprouting. Here, the authors report that MODD (mediator of OsbZIP46 deactivation and degradation) negatively regulates seed dormancy by inhibiting the transcriptional activity of ABSCISIC ACID INSENSITIVES (ABIs).
Crack formation typically results in random patterns and material failure. Inspired by plant phototropism, the authors use plasmonic absorbers to control crack propagation in colloidal films with light, showcasing a robust, programmable self-assembly process.
Transcriptional cell states can drive treatment resistance in cancer. Here, the authors develop ReSisTrace to predict cell states that are primed to resist ovarian cancer treatment and validate their findings using small molecule inhibitors.
New mass-balance calculations show that the bulk chemistry of the ocean is strongly influenced by flow of seawater through sediments deep within continental shelves, with implications for global carbon budgets.
The dynamic protein corona hinders the uptake of nanocarriers in desired target cell populations, limiting their bench-to-bedside translation. Here the authors reveal that the modification of hydroxyl and amino functional groups on nanovesicles can rationally regulate the composition of protein coronas to improve the efficiency of targeted drug delivery.
In this work, the authors report the use of a computationally and rationally designed self-assembling peptide that has robust antiviral capability with demonstrated specificity in binding to SARS-CoV-2 and inhibition of viral entry into human cells.
Prion-like domains are intrinsically disordered regions found in many RNA- and DNA-binding proteins. Here, the authors show that these domains can drive sequence-specific co-phase separation of chromatin remodeling complex with FET oncofusion proteins.
Paired electrolysis is challenging without membrane and redox mediators. The authors developed a one-pot, mediator-free, and scalable e-synthesis of γ-butyrolactone (GBL) from furoic acid with high yield and selectivity in an aqueous electrolyte.
VCP/p97 is identified as a co-factor to the fusion oncoprotein ASPSCR1::TFE3. They co-localize on chromatin, co-dependent for enhancer looping and transcriptional regulation in alveolar soft part sarcomas and Xp11- rearranged renal cell carcinomas.
Fine-tuning the expression of biosynthetic pathway genes is crucial to improve microbial production titres. Here, the authors present GEMbLeR, an optimization strategy to balance the expression of multiple genes simultaneously over a wide range.
Charge-to-spin conversion allows for the generation and control of spin polarization via a charge current. Typically, this is done with non-magnetic materials with large spin-orbit interactions such as Platinum. Herein, Dai et al demonstrate an intriguing charge-to-spin mechanism, a magnetic spin Hall effect, in a van der Waals heterostructure.
Extracellular vesicles (EVs) play a crucial role in intercellular communication by transferring bioactive molecules from donor to recipient cells. Here, the authors show that EVs play a crucial role in activating immune responses through cell fusion, shedding light on their impact on inflammation.
