Bioorthogonal chemical labelling of endogenous neurotransmitter receptors in living mouse brains

This paper develops a method to label endogenous neurotransmitter receptors in living mouse brains using LDAI chemistry, enabling spatial mapping and dynamic analysis of receptors in health and disease.

Pulvinar Slits: Cellulose-deficient and De-Methyl-Esterified Homogalacturonan-Rich Structures in a Legume Motor Cell

This study characterizes the unique cell wall structure of legume cortical motor cells, identifying pulvinar slits with specific pectin composition and deformability.

Morphological variation and phylogeny of Karenia selliformis (Gymnodiniales, Dinophyceae) in an intensive cold-water algal bloom in eastern Hokkaido, Japan in September-November 2021

The paper examines the morphology and phylogeny of Karenia selliformis and other co-occurred dinoflagellates in a harmful algal bloom in eastern Hokkaido, Japan, identifying morphological variation and genetic similarity to a bloom in Kamchatka, Russia.

Single-cell dynamics of pannexin-1-facilitated programmed ATP loss during apoptosis

The paper develops FRET biosensors to show that caspase-3 activation initiates a programmed loss of ATP in apoptotic cells via pannexin-1 cleavage, which arrests metabolic activity.

The linear ubiquitin chain assembly complex generates heterotypic ubiquitin chains

This study shows LUBAC generates heterotypic ubiquitin chains with linear and oxyester-linked branches through coordinated action of HOIP and HOIL-1L.

Crystal structure of β-L-arabinobiosidase belonging to glycoside hydrolase family 121

The paper presents the crystal structure of β-L-arabinobiosidase (HypBA2) from Bifidobacterium longum, revealing its catalytic mechanism and conserved residues essential for substrate binding and catalysis.

High-throughput Analysis of Arabidopsis Stem Vibrations to Identify Mutants with Altered Mechanical Properties

This paper introduces AraVib and AraVibS software to analyze plant stem vibrations and identify mutants with altered mechanical properties using video data and simple equipment.
