Unraveling the structural origin of liquid anomalies remains a challenging topic. Xu et al. propose a folded-network structural model for molten tin and provide insights into the observed second-order-like structural transition.
What are the minimal hardware requirements for a given class of sensing problems? Here, authors investigate this while proposing a miniaturized near-infrared spectral sensor, based on an array of resonant-cavity enhanced photodetectors, and capable of operating without the need for spectral reconstruction.
The origins of deformation twins in Mg have remained unclear in the past. Here the authors, by combining in situ experimental observations and atomistic simulations, capture the rapid twinning phenomena in Mg crystals and show that twinning occurs through pure atomic shuffle.
The authors present a strategy to construct dynamic biomolecular landscapes. Here, they derive a quantitative description of the distribution timescales and amplitudes of reorientational motion of POPC membranes from the combination of NMR relaxation data and frame analysis of MD simulations.
The authors report nickel-porphyrins derivatives of chlorophyll in ~1 Gyr-old multicellular eukaryotes, preserved in low-grade metamorphic rocks. This brand new approach permits to identify early phototrophic organisms through the geological record.
Invasive micropapillary carcinoma (IMPC) is a highly metastatic rare form of breast cancer but its genomic alterations are largely unknown. Here, the authors show that monoclonal metastatic ancestors share copy-number loss of PRDM16 and IGSF9 and gain of ALDH2 in primary samples from IMPC patients.
Photoresponsive compounds have potential applications in various fields, including the development of smart materials and switches. Here the authors report a gold(I) complex that undergoes multiple photoinduced color changes upon excitation of light at specific wavelengths, offering an enhanced storage capacity towards optical memory devices.
It remains unclear whether improvements in one cognitive task transfer to other tasks. Here, the authors show that changes in prefrontal neuronal activation, firing rate, and local field potentials induced during active learning of a working memory task are also evident in a control task.
Whether G-quadruplexes (G4s) regulate stem cell self-renewal and fate determination during embryonic development is not well understood. Here, the authors reveal that the embryonic stem cell state is defined by very high G4 abundance. G4s are progressively lost during differentiation as cells transit to lower lineage potential while artificial G4 stabilisation leads to delayed differentiation.
The surface octahedral tilt in exfoliated 2D perovskites is directly visualized by STM and the degree of the tilt varies with the number of layers of inorganic slabs and result in different amounts of excitonic red shift in photoluminescence.
Different phosphoinositide isomers are involved in a variety of physiological and pathological processes. Here, the authors combine chiral column chromatography and mass spectrometry to measure phosphoinositide regioisomers, revealing their dynamic changes in intra- and extracellular cancer cell milieus.
Multiple drugs have been in the past associated with myocarditis. Here the authors perform a pharmacovigilance study and analyze 5108 reports of drug-induced myocarditis reporting temporal trends and overall mortality and identifying emerging drug classes among the treatments associated with myocarditis.
Post-translational modifications (PTMs) can regulate cellular protein function but their global impact on protein turnover is largely unknown. Here, the authors develop proteomic workflows to profile PTM-resolved protein turnover and analyze the effects of phosphorylation, acetylation and ubiquitination.
Gioblastoma tumours consist of different niches defined by histology. Here, the authors use proteomics and machine learning to assign protein expression programs to these niches, and reveal that KRAS and hypoxia are associated with drug resistance.
The human silencing hub (HUSH) complex, which includes TASOR, deposits repressive marks on HIV proviruses, resulting in gene repression. Here, Matkovic et al. show that TASOR interacts with RNA Polymerase II, predominantly under its elongating state, and RNA degradation proteins to repress HIV provirus expression.
Alzheimer’s disease is associated with changes in astrocytes. Here the authors investigated the astrocyte translatome associated with amyloid-ß and tau pathology.
Increasing evidence suggested that dysregulation in lipid metabolism is linked to OA pathogenesis, but the underlying regulatory mechanism is not well understood. Here, the authors show that PPARα-ACOT12 signalling regulates cartilage homeostasis by regulating de novo lipogenesis in mice.
