The haematopoietic cytokine thrombopoietin (Tpo) is the primary regulator of megakaryocyte and platelet numbers. Here authors present a structural and biochemical characterization of how Tpo binds to its receptor to induce signaling.
Early detection and accurate diagnosis of focal liver lesions are crucial for effective treatment and prognosis. Here, the authors present a fully automated diagnostic system that leverages multi-phase CT scans and clinical features, for diagnosing liver lesions.
Here the authors identify gene targets and causal cell types affected by genetic risk loci in uterine fibroids by combining meta-analysis on existing fibroid genome-wide association studies and integrated the identified risk loci and potentially causal single nucleotide polymorphisms with epigenomics, transcriptomics, 3D chromatin organization from diverse cell types as well as primary uterine fibroids patient’s samples.
NLRP3 is a critical intracellular inflammasome sensor and an important clinical target against inflammation-driven human diseases. Here, the authors determined Cryo-EM structures of human NLRP3 in its closed and open states, elucidating the mechanism of NLRP3 inflammasome activation.
Inspired by thermal optocapacitive approaches at regulating neuronal activity, the authors explore a photolipid-based non-thermal optocapacitive method that allows for regulating voltage-gated and mechanosensitive ion channels using light.
The cuneiform nucleus regulates locomotor activity. Here the authors show that this nucleus has a more context-dependent role than previously thought, whereby GABAergic projections from the zona incerta act to promote exploratory behaviour in mice.
Optics used for X-ray focusing suffer from wavelength dependent effects like chromatic aberration. Here the authors demonstrate fabrication of a ultracompact Kirkpatrick-Baez mirror and use it for achromatic focusing to 20 nm spot for the soft X-ray at 2-keV photon energy.
In this work, the authors report NMR lipids Databank to promote decentralised sharing of biomolecular molecular dynamics (MD) simulation data with an overlay design. Programmatic access enables analyses of rare phenomena and advances the training of machine learning models.
Nickel-based electrocatalysts for the hydrogen oxidation reaction in hydroxide exchange membrane fuel cells show promise, but their activity requires further enhancement. Here, the authors report NiCuCr alloy with high activity, owing to the efficient tuning of both hydrogen and water binding on Ni sites by alloying with Cu and Cr.
The activity of Drosophila male germline stem cells is tightly regulated by a cluster of somatic niche cells. Here they find that Dpp induces opposed cellular responses in stem cells versus in differentiating descendants, thereby ensuring spatial control of the niche with a single factor.
Analysis of capacitive behavior of electrode materials used in batteries and pseudocapacitors is challenging. Here, authors report an electrochemical signal analysis method available as an online tool to classify the charge storage behavior of a material as battery-like or a pseudocapacitor-like.
Cells exert tight control over the size of their compartments in order to regulate their function. Here, nuclear fluorescence exclusion microscopy is able to measure the nuclear and cytoplasmic volumes of live cells in a high-throughput way.
R.-J. Slager et al. extend the theory of multigap topology from static to non-equilibrium systems. They identify Floquet-induced non-Abelian braiding, resulting in a phase characterized by anomalous Euler class, a multi-gap topological invariant. They also find a gapped anomalous Dirac string phase. Both phases have no static counterparts and exhibit distinct boundary signatures.
Under-oil open microfluidic systems have potential for studying multi-phase chemical reactions but have so far demonstrated largely only for biological applications. Here, the authors report the development of a system for in situ characterization of gas-liquid reactions by Raman spectroscopy.
Organic heterostructures with controlled geometry on the micro and nanoscale are important in nanotechnology, but epitaxial growth processes with high lattice mismatching are challenging to achieve. Here, the authors report a visualisation process for morphology evolution on epitaxial growth.
Elemental immiscibility limits the development of solid solution materials. Here, authors create a nonequilibrium flame aerosol method to mix nearly any pair of metal elements in a single-phase nano-ceramic. Also, an exsolution behavior is presented to produce active and stable nanoparticles.
An engineered sensor NLR RGA5HMA5 carrying multiple resurfaced interfaces was generated to confer complete resistance to the rice blast fungus strains expressing the non-corresponding effector AVR-PikD, paving a way to broaden the resistance spectra of NLRs.
Focused ultrasound could be used to change the geometry of implanted shape-memory medical devices noninvasively. Here, the authors demonstrate this concept on large animal models, showing device removal and trigger drug release.
Resistance to chemotherapy for soil-transmitted helminth infection has been detected in veterinary settings but not yet in human infections. Here, the authors investigate the risk of resistance in humans and how it may change as a result of scaling-up preventative deworming programs.
In glioblastoma (GBM), tumour microtubes (TM) connect tumour cells to a broader cellular network, with roles in tumour progression and therapy resistance. Here, the authors combine a dye uptake method in GBM xenograft models with subsequent scRNA-seq to infer a TM connectivity signature, finding CHI3L1 as a marker of connectivity.
