ZSL Orchestrates Synaptonemal Complex Assembly as a Central Region Scaffold to Ensure Synapsis Fidelity and Crossover Control in Polyploid Meiosis

open access: yesAdvanced Science, Volume 13, Issue 27, 13 May 2026.
A central molecular adaptor, ZSL, is identified that links transverse filaments ZYP1 to central element SCEP1/2 to drive synaptonemal complex assembly in Brassica napus. Loss of ZSL abolishes synaptonemal complex formation, disrupts meiotic chromosome segregation, and markedly increases crossovers, providing mechanistic insight into meiotic fidelity ...

Ligand‐driven modulation of chaperone–cochaperone networks shapes proteostasis outcomes

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Protein homeostasis depends on a delicate interplay between folding and degradation, orchestrated by molecular chaperones. Among them, Hsp90 is a central hub, regulating nearly 10% of the proteome through ATP‐driven conformational cycles and selective interactions with cochaperones.

The optimality‐based active region model for fingering flow in the vadose zone: Theory, model validation, and generalization

open access: yesVadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Traditional macroscopic models for water flow in the vadose zone often assume local equilibrium within a representative element volume. However, under fingering flow this assumption breaks down on a macroscale involving sub‐grid figuring because local equilibrium does not hold between the fingering and non‐fingering domains.

Meso‐ to Submesoscale Variability of Particulate Carbon Export Captured by a Glider‐Camera System in the Northeast Atlantic During the APERO Campaign

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Between 9 June and 6 July 2023 a SeaExplorer glider equipped with an Underwater Vision Profiler (UVP6), surveyed frontal structures between a cyclonic and two anticyclonic eddies in the Northeast Atlantic as part of the APERO cruise (Assessing marine biogenic matter Production, Export and Remineralization: from the surface to the dark Ocean ...

Stancu modified operators revisited

open access: yesJournal of Numerical Analysis and Approximation Theory, 2002
In this paper we construct a general positive approximation process representing an integral form in Kantorovich sense of the Stancu operators. By using K-functionals and some moduli of smoothness we give direct theorems for pointwise approximation. Also,

HTLV‐1 Tax Reshapes the DNA‐Binding Pattern of Transcription Factor IRF4 and Disrupts Host Gene Regulation

open access: yesCancer Science, Volume 117, Issue 5, Page 1497-1509, May 2026.
Proteomic mapping of Tax complexes in HTLV‐1–infected T‐cells identified IRF4 as a Tax interactor. Chromatin profiling showed Tax reprograms IRF4 occupancy with H3K27ac gains at super‐enhancers; Tax–IRF4 co‐expression altered chromatin accessibility and transcription, and ATL‐associated IRF4 mutants partially phenocopied these changes. ABSTRACT Human T‐

The Development of Temporal Memory for Complex Events

open access: yesDevelopmental Science, Volume 29, Issue 3, May 2026.
ABSTRACT Remembering when past events occurred is a key component of episodic memory, yet its developmental trajectory remains only partially understood. This study examined how children aged 6 and 10, compared to young adults, recall the timing of events embedded in an 11‐min cartoon.

Fixed point results for contractions of polynomial type

open access: yesDemonstratio Mathematica
We introduce two new classes of single-valued contractions of polynomial type defined on a metric space. For the first one, called the class of polynomial contractions, we establish two fixed point theorems.

Existence and Stability of Solutions for p-Proportional ω-Weighted κ-Hilfer Fractional Differential Inclusions in the Presence of Non-Instantaneous Impulses in Banach Spaces

open access: yesFractal and Fractional
In this work, we introduce a new definition for the fractional differential operator that generalizes several well-known fractional differential operators.
