Chemical inhibition of stomatal differentiation by perturbation of the master-regulatory bHLH heterodimer via an ACT-Like domain

This study identifies Stomidazolone as a chemical inhibitor of the bHLH heterodimer MUTE-SCREAM, disrupting stomatal differentiation in plants.

Rapid propagation of Ca2+ waves and electrical signals in a liverwort Marchantia polymorpha

This study shows that the liverwort Marchantia polymorpha propagates Ca2+ waves and electrical signals rapidly in response to wounding, similar to vascular plants, involving GLR channels.

Automated escape system: identifying prey's kinematic and behavioral features critical for predator evasion

This study develops an automated escape system to identify prey kinematic and behavioral features critical for predator evasion, showing that escape speed and reaction distance significantly affect predator-prey interactions.

CD4+ T-cell immunity of SARS-CoV-2 patients determine pneumonia development

This study identifies a specific CD4+ T-cell cluster associated with reduced pneumonia risk in SARS-CoV-2 patients, suggesting immune imbalance contributes to severe disease.

Evidence of the simultaneous replications of active viruses in specimens positive for multiple respiratory viruses

The paper confirms simultaneous replication of multiple respiratory viruses in low-copy-number specimens using HBTEC-ALI cultures.

A bi-kinase module sensitizes and potentiates plant immune signaling

The paper identifies a Ca2+ sensing bi-kinase module that enhances NADPH oxidase activation through mutual trans-phosphorylation, enabling systemic immunity in plants.

Cardiac hemodynamics and ventricular stiffness of sea-run cherry salmon (Oncorhynchus masou masou) differ critically from those of landlocked masu salmon

This study compares cardiac hemodynamics and ventricular stiffness between sea-run cherry salmon and landlocked masu salmon, finding significant differences in diastolic function and ventricular stiffness.

Multifaceted effects of variable biotic interactions on population stability in complex interaction webs

This study examines how variability in biotic interactions affects population stability in response to pesticide application in freshwater communities.

Transient induction of cell cycle promoter Fam64a improves cardiac function through regulating Klf15-dependent cardiomyocyte differentiation in mice

This study shows that transient activation of Fam64a improves cardiac function in adult mice by promoting cardiomyocyte proliferation without excessive dedifferentiation.

Spatial metabolomics using imaging mass spectrometry to identify the localization of asparaptine in Asparagus officinalis

The paper uses spatial metabolomics to locate asparaptine in asparagus spears, showing its accumulation in lateral shoots and validating findings with LC-MS/MS.

Asymbiotic mass production of the arbuscular mycorrhizal fungus Rhizophagus clarus

This study shows that combining strigolactone and methyl jasmonate with myristate and organic nitrogen in asymbiotic cultures of Rhizophagus clarus HR1 increases spore production and infectivity, supporting plant growth.

Centriole and PCM cooperatively recruit CEP192 to spindle poles to promote bipolar spindle assembly

This study shows that centrioles and PCM cooperatively recruit CEP192 to spindle poles, promoting bipolar spindle formation in human cells.

Perception of and anxiety about COVID-19 infection and risk behaviors for spreading infection: An international comparison

This study compares public perception, anxiety, and risk behaviors related to COVID-19 across Japan, the UK, and Spain using survey data.

Fundamental resource specialization of herbivorous butterflies decreases toward lower latitudes

This study finds that fundamental resource specialization of herbivorous butterflies increases with latitude, driven by climate, diversity, and body size, contrary to the common assumption about realized specialization.

Basicity of N5 in semiquinone enhances the rate of respiratory electron outflow in Shewanella oneidensis MR-1

This study shows that the basicity of N5 in semiquinone cofactors enhances the rate of extracellular electron transport in Shewanella oneidensis MR-1 by facilitating protonation-dependent electron outflow.

The first functional characterization of ancient interleukin-15-like (IL-15L) reveals shared and distinct functions of the IL-2, -15 and -15L family cytokines

This study characterizes the functional roles of IL-15L in rainbow trout, revealing shared and distinct functions compared to IL-2 and IL-15, and provides insights into cytokine family evolution.

Single-cell transcriptomics reveals expansion of cytotoxic CD4 T-cells in supercentenarians

This study identifies an increase in cytotoxic CD4 T-cells and a reduction in B-cells in supercentenarians through single-cell transcriptomics.

Disease-associated mutations hyperactivate KIF1A motility and anterograde axonal transport of synaptic vesicle precursors

This study shows that disease-associated KIF1A mutations hyperactivate motor activity, leading to increased anterograde axonal transport of synaptic vesicle precursors and contributing to motor neuron disease.

OVOL2 induces mesenchymal-to-epithelial transition in fibroblasts and enhances reprogramming to epithelial lineages

This study identifies OVOL2 as a key factor that induces mesenchymal-to-epithelial transition in fibroblasts and enhances reprogramming to epithelial lineages.

DETECTION OF Wolbachia IN FIELD-COLLECTED MOSQUITO VECTOR, Aedes aegypti

The paper detects Wolbachia in field-collected Ae. aegypti mosquitoes using PCR markers, finding 16.8% infected by wsp and 13.2% by 16S rDNA, with most sequences aligning to supergroup B.

Geographical co-occurrence of butterfly species: The importance of niche filtering by host plant species

This study examines geographical co-occurrence patterns of 232 butterfly species in Japan, finding that host plant sharing promotes co-occurrence through niche filtering rather than competition.
