Rapid investigation of chemical reactions is a challenge in bio-medical analysis. Here, the authors demonstrate sensitive in-situ real-time reaction-monitoring of conformational changes in protein solution, based on a fingertip-sized mid-IR lab-on-a-chip.
Cells employ global genome nucleotide excision repair to repair a broad spectrum of genomic DNA lesions. Here, the authors reveal how chromatin is primed for repair, providing insight into mechanisms of chromatin plasticity during DNA repair.
Phenotypic and genotypic evolution in worrisome Klebsiella spp. is influenced by the capsule. Here the authors show that adaptation outside the host can impact virulence-associated traits, including de novo emergence of hypermucoviscosity.
Chondroitin sulfate (CS) is one of the most abundant glycosaminoglycans in prostate cancers. Here the authors show that inhibition of the androgen receptor pathway leads to the upregulation of CS, which promotes prostate cancer growth and metastasis.
Processing sensory stimuli requires coordinated activation of neurons broadly distributed across many distant cortical sites, yet it is not clear how this coordination is accomplished in the brain. Here, the authors show that visual stimuli reliably evoke traveling waves of activity that percolate through the cortex and orchestrate neuronal firing across primary visual and association cortices.
Dynamic remodeling of the actin cytoskeleton underlies cell movement, but is challenging to characterize at the molecular level. Here, the authors present a method to extract actin filament velocities in living cells, and compare their results to current models of cytoskeletal dynamics.
Backward contact tracing aims to identify individuals who were infected by the same person as infected an index case, and has been shown to be effective in modelling studies of SARS-COV-2. Here, the authors present empirical data of the effectiveness of backward contact tracing from a program amongst university students in Belgium.
Here, the authors find the missing link for soliton microcombs that exist at the boundary where the group velocity dispersion of light changes sign: zero-dispersion solitons. The resulting microresonator frequency comb, based in Si3N4, spans almost an octave.
Determination of interactions between native proteins in cells is important for understanding function. Here the authors report MolBoolean as a method to detect interactions between endogenous proteins in subcellular compartments, using antibody-DNA conjugates for identification and signal amplification.
In contrast to the prevalence of 1,3-dipolar cycloadditions, radical [3+2] annulations of alkynes are underexplored. Here, the authors describe [3+2] cycloadditions of various internal alkynes with readily accessible aliphatic aldehydes via photoinduced decatungstate catalysis.
Here, the authors report tunable luminescence from a single lanthanide ion upon changing excitation conditions through co-doping an energy-modulator ion, thus adjusting the photon transition process of the lanthanide activator ion. Optical encryption has also been demonstrated as an application of this universal strategy.
Molecular flexiblity and conformational dynamics of chiral catalysts are not often taken into account in models of enantiodiscrimination. Here the authors design a catalytic system in which two conformers of the same catalyst can lead to axially chiral products of opposite absolute configurations.
In this study, Teng et al. identify a population of glutamatergic neurons in the ventrolateral medulla that control Non-Rapid Eye Movement (NREM) sleep in mice. They uncover an excitatory brainstem-hypothalamic circuit that controls wake-sleep transitions.
Modelling of aggressive lymphomas, such as double hit lymphoma, has been challenging. Here the authors engineer a CRISPR activation mouse to enable the generation of these aggressive lymphomas and identify the pro-survival BCL-2 protein A1 as a venetoclax resistance factor.
Quantum interference effect in the conductance of single molecule junctions has been attracting intensive interest in recent years. Here, Li and Selzer show the presence of intermolecular quantum interference over 40,000 molecules in a molecular ensemble junction with bismuth as the top electrode.
Aqueous organic redox flow batteries are affected by short cycle life and low capacity. Here, the authors develop composite dihydroxyanthraquinone/polymer anolytes capable of improving the cycling stability and discharge capacity of aqueous organic redox flow batteries.
The human pathogen Mycobacterium tuberculosis requires a metal exporter, CtpC, for resistance to zinc poisoning. Here, the authors show that zinc resistance also depends on a chaperone-like protein that binds zinc ions, forms high-molecular-weight complexes with CtpC in the cytoplasmic membrane, and is required for CtpC function.
Nanosized Pd-based catalysts are widely used in the direct hydrogen peroxide (H2O2) synthesis from H2 and O2, while the selectivity and yield of H2O2 remain inferior. Here, a remarkable H2O2 yield of 115 mol/gPd/h and H2O2 selectivity higher than 99% are reported using a Pd single-atom catalyst for the direct synthesis of H2O2.
A 2D magnet CrSBr has attracted interest for applications in spintronics due to its high critical temperature and interesting magneto-electrical properties. Here the authors report a detailed study of its magnetic and structural phases and uncover a hidden magnetic order inside the magnetically-ordered phase.
