Correlating Vibrational Spectra to C1 Surface Species on Nickel‐Based Hydrogenation Catalysts Using Density Functional Theory

ChemistryEurope, Volume 4, Issue 4, April 2026.
A method is presented to correlate calculated vibrational frequencies with experimentally measured infrared (IR) spectra for C1‐heterogeneous catalytic reactions on nickel surfaces. Vibrational frequencies were computed using density functional theory for 14 key intermediates.

Spatial omics for profiling the dynamic tumor microenvironment

Clinical &Translational Immunology, Volume 15, Issue 4, 2026.
Spatially resolved transcriptomics and proteomics map RNA/protein in intact tumor tissues, revealing crucial cancer–immune interactions across the different stages of tumor evolution. Integrating AI promises translational impact, but gaps in cross‐platform integration, standards, compute, validation and interpretability remain.

Uncovering Immune Niches in Health and Disease Using Spatial Transcriptomics

European Journal of Immunology, Volume 56, Issue 4, April 2026.
Through the lens of spatial transcriptomics and associated tools, novel immune niche constituents can now be resolved. Drawing on gut and tumor contexts, we propose a framework to define immune niches and integrate clonal dynamics, aiming to advance niche‐directed therapies toward precise, context‐specific immune modulation.

Filament Extrusion‐Based Conductive TPU Composite Scaffolds Enable Superior Neuronal Growth and Synaptic Maturation In Vitro

Engineering in Life Sciences, Volume 26, Issue 4, April 2026.
ABSTRACT Fused filament fabrication (FFF) three‐dimensional (3D) printing technologies offer new opportunities for fabricating customizable, low‐cost platforms for tissue engineering applications. Here, we developed and characterized 3D‐printed scaffolds using conductive thermoplastic polyurethane (cTPU) filaments and evaluated their mechanical ...

Integrating Experimental Imaging and (Quantum‐Deformation)‐Curvature Dynamics in Bleb Morphogenesis

Engineering Reports, Volume 8, Issue 4, April 2026.
We propose a (q,τ)$$ \left(q,\tau \right) $$‐fractional geometric flow model for cell blebbing that incorporates hereditary memory and viscoelastic effects in curvature‐driven membrane dynamics. Image‐based measurements of bleb geometry are coupled with fractional evolution equations and validated numerically.

Compartmental Modeling of Woodland Ecosystem Services for Evaluating Urban Natural Capital in Sustainable Cities

Engineering Reports, Volume 8, Issue 4, April 2026.
Proposed engineering data governance model for ecosystem services within the context of natural capital and sustainable cities, using woodland as a case study. This model is inspired by the generalized natural capital logic chain outlined by Natural England, supported by insights from the Office for National Statistics report and aligned with the ...

Testing for Network Specificity in Brain‐Behavior Associations Using Ordinal Dominance Curves

Human Brain Mapping, Volume 47, Issue 5, 1 April 2026.
NETDOM is a novel statistical framework for testing whether brain–behavior associations within a region of interest are both significantly greater than zero and larger than associations outside of the selected region. ABSTRACT Interpreting brain‐behavior relationships through the lens of anatomical parcellations or functional networks is commonplace in
