In this study, the authors report that bat H9N2 influenza A virus replicates and transmits in ferrets, efficiently infects human lung explant cultures, evades MxA antiviral activity in mice, and has low antigenic similarity to seasonal N2, meeting pre-pandemic criteria.
In this study, the authors report that a bat influenza A (H9N2) virus shows receptor binding features similar to avian influenza viruses, efficiently infects ex-vivo human respiratory cells and replicates in the lungs of mice and upper respiratory tract of ferrets following airborne transmission.
The precise regulatory mechanisms controlling ciliary Hedgehog signaling remain incomplete. Here, the authors use ciliary proteomics to reveal that Numb facilitates the endocytosis of the receptor Ptch1 from the ciliary pocket, thereby enabling activation of Hedgehog signaling.
DDX3X is a member of the RNA helicase family, which remodels RNA structures. Using solution NMR, here the authors show that DDX3X preferentially binds to single-stranded RNA, which underlies its unwinding activity toward various structured RNA substrates.
The development of fluorescent polymer hydrogels without the use of extended pi-conjugation is challenging. Here, the authors report the use of clustering-trigger emission to give red fluorescence on boiling polymer hydrogels, with tuneable emission properties.
Knowledge of pathogenesis mechanisms and effective treatments for viral myocarditis is lacking. Here, Wang et al show that loss of TRIM29 and PERK inhibitor mitigate viral myocarditis by attenuating PERK-driven ER stress and ROS responses in male mice.
Whether and how hypothalamic neurons can lose or change their identity in adulthood has remained elusive. Here, the authors show that mature pro-opiomelanocortin (Pomc) neurons contain invisible ‘Ghost’ subsets with atypical identities that are recruited in response to obesogenic stimuli.
Ising machines are promising for solving NP-hard problems, but current implementations have power consumption and scalability challenges. Si et al. implement an Ising machine consisting of 80 superparamagnetic tunnel junctions with all-to-all connections and apply it to a large-scale travelling salesman problem.
Kalium channelrhodopsins (KCRs) are promising tools for optogenetic silencing. Here, the authors show that KCRs inhibit cellular excitability in flies, worms, and fish, establishing them as first-line tools for inhibiting diverse types of excitable cells.
Streptococcus dysgalactiae subsp. equisimilis is closely related to Streptococcus pyogenes and colonises the same sites in humans. This study examines cross-species transmission interactions and genetic exchange in a high disease burden setting.
Thin crystals grown on rigid spherical templates of increasing curvature exhibit increased protrusions. Here, the authors demonstrate the opposite curvature effect on the morphology of molecularly thin crystals grown within elastic fluid membranes, like those of biological cells.
Prior work has identified a male-only effective population size bottleneck 3-5000 years ago. While violent competition has been proposed as a cause, the authors here show that a segmentary patrilineal system with lineal fission provides a peaceful alternative explanation.
Whether bacterial replisome progression follows a “factory” or “track” model remains a long-standing controversy. Here, the authors find that cells can switch between the two models, in a process governed by dynamic chromosome organization processes.
The authors present DenRAM, a hardware realization of spiking neural network with dendritic architecture. It utilizes memristive devices to implement both delay and weight parameters, enhancing low-power signal processing with reduced memory use.
Here, authors demonstrate the electrohydrodynamic printing of alkylated 3,4-dihydroxy-L-phenylalanine functionalized MXene (AD-MXene) ink. The AD-MXene outperforms vacuum-deposited Au and Al electrodes, providing thin film transistors with good environmental stability due to its hydrophobicity.
Large-scale eDMFT computation reveals that FeO undergoes a gradual orbitally selective insulator-metal transition across the extreme conditions of Earth’s interior, with implications for compositions and conductivity of the core-mantle boundary region.
Intraflagellar transport is essential for the formation and function of cilia. Here, the authors use single-molecule imaging in live C. elegans to show that transport trains are formed by the sequential attachment of proteins before departing into the cilium.
