Cell Mechanics in Cancer: Integrating Mechanotransduction Pathways Within the Tumor Microenvironment

open access: yesJournal of Cellular Physiology, Volume 241, Issue 5, May 2026.
ABSTRACT Single‐cell mechanical properties such as stiffness, elasticity, and viscosity, are crucial in governing biological processes like migration, proliferation, and differentiation. In cancer, the mechanical properties of cells undergo significant alterations, which contribute to tumor growth, metastasis, and resistance to therapy.

Transition From Land to Sea: Comparative Genomics Illuminates the Adaptive Evolution of the Intertidal Spider

open access: yesMolecular Ecology Resources, Volume 26, Issue 4, May 2026.
ABSTRACT Spiders are renowned for their ecological versatility and silk‐based innovations in materials science, yet marine environments remain virtually uncolonized by this predominantly terrestrial lineage. A striking exception is the obligate intertidal spider genus Desis, whose members have evolved extraordinary physiological and behavioural ...

Serial Spatial Transcriptomes Reveal Regulatory Transitions in Maize Leaf Development

open access: yesPlant Biotechnology Journal, Volume 24, Issue 5, Page 2787-2810, May 2026.
ABSTRACT Plant leaves originate from the shoot apical meristem (SAM) and undergo a developmental process of highly coordinated gene expression regulation. To date, only a few key regulators have been identified and characterised, so the gene expression cascades responsible for leaf cell specification and differentiation from SAM remain largely elusive.

Operando Investigation of Mechanochemically Synthesized Ni‐Based Metal–Organic Frameworks for Electrocatalytic Alcohol Oxidation

open access: yesChemSusChem, Volume 19, Issue 8, 28 April 2026.
A nickel‐based metal–organic framework (Ni‐MOF) with mixed N‐ and O‐donor linkers was synthesized via both mechanochemical and solvothermal routes and evaluated as an electrocatalyst for alcohol oxidation reactions (AORs). Despite having identical crystal and electronic structures, the mechanochemically synthesized Ni‐MOF (termed as MC‐MOF) exhibited ...

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures

open access: yesAdvanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.
This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed
