In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

Cytoskeleton, Volume 83, Issue 6, Page 394-406, June 2026.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Diversity in Evolutionary Status and Magnetic Activity among Solar-type Twin Detached Eclipsing Binaries

The Astrophysical Journal Supplement Series
We present a combined photometric and spectroscopic analysis of four detached eclipsing binaries (KIC 8957954, KIC 10593759, KIC 8302455, and TIC 207398432), all of which exhibit composite G-type spectra and nearly equal mass ratios. Based on survey data

High‐Content Immunofluorescence Quantification of Transcription Factors: Application to pSMADs for BMP/TGFβ Signaling Pathways

Current Protocols, Volume 6, Issue 6, June 2026.
Abstract High‐throughput immunofluorescence (IF) detection has become an essential tool in drug discovery for analyzing multiple markers and providing insights into cellular pathways. While IF techniques have been established for decades, high‐content IF protocols vary among laboratories, highlighting the need for standardized and quantitative ...

The Benchmark Eclipsing Binary V530 Ori : A Critical Test of Magnetic Evolution Models for Low-Mass Stars

, 2015
We report accurate measurements of the physical properties (mass, radius, temperature) of components of the G+M eclipsing binary V530 On. The M-type secondary shows a larger radius and a cooler temperature than predicted by standard stellar evolution ...

Discovery and Characterization of the Totally Eclipsing Binary TIC 189854044 in the Young Open Cluster ASCC 23

The Astronomical Journal
Mass segregation is a fundamental prediction of dynamical relaxation in stellar systems, yet direct evidence in young open clusters remains scarce. Here, we report the discovery and characterization of a totally eclipsing binary system (TIC 189854044) in

Identification and Functional Characterization of Isoflavone synthase Gene Family in Pea (Pisum sativum): The Entry Point to Pisatin Biosynthesis

Legume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Isoflavone synthase (IFS), a cytochrome P450 monooxygenase of the CYP93C subfamily, catalyzes the conversion of flavanones into isoflavones, the first committed step in the biosynthesis of isoflavonoid phytoalexins. In pea (Pisum sativum L.), the phytoalexin pisatin plays a pivotal role in defense against pathogens.

Fundamental effective temperature measurements for eclipsing binary stars – VII. The solar twin in LL Aquarii

The eclipsing binary LL Aqr is a bright V=9.32, detached system consisting of two solar-type stars in an eccentric orbit (P = 20.2 d). The secondary component, LL Aqr B, was previously found to have physical and atmospheric parameters very similar to the

Structural Characterization of Cardiac Free‐Running Purkinje Fibers Using Inhomogeneous Magnetization Transfer (ihMT): A Proof of Concept MRI‐Histology Approach

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
The cardiac Purkinje network is essential for synchronized ventricular activation but remains difficult to visualize with conventional MRI due to limited structural contrast. This study demonstrates that inhomogeneous magnetization transfer imaging provides enhanced contrast that differentiates free‐running Purkinje fibers, Purkinje‐Myocardial Junction,
