Characterizing Stage‐Specific Cellular Dynamics and Microenvironmental Remodeling in Lung Adenocarcinoma by Single‐Cell RNA Sequencing

Advanced Science, Volume 13, Issue 9, 13 February 2026.
This study integrated early‐stage patient specimens with publicly available datasets encompassing non‐malignant lung tissues and advanced‐stage LUAD through single‐cell sequencing, revealing a dynamically remodeled tumor microenvironment characterized by a hypoxia‐adapted malignant subset (C5), immunosuppressive LGMN+ macrophages, STAT1‐driven ...

A Generative Model for Realistic Galaxy Cluster X-Ray Morphologies

The Astrophysical Journal
The X-ray morphologies of clusters of galaxies display significant variations, reflecting their dynamical histories and the nonlinear dependence of X-ray emissivity on the density of the intracluster gas. Qualitative and quantitative assessments of X-ray

Turbulence and Mixing in the Intracluster Medium

, 2009
The intracluster medium (ICM) is stably stratified in the hydrodynamic sense with the entropy $s$ increasing outwards. However, thermal conduction along magnetic field lines fundamentally changes the stability of the ICM, leading to the "heat-flux ...

Spatial analysis of HPV‐associated cervical intraepithelial neoplastic tissues demonstrate distinct immune signatures associated with cervical cancer progression

The Journal of Pathology, Volume 268, Issue 2, Page 200-214, February 2026.
Abstract Cervical cancer remains the fourth most common cancer affecting women worldwide, and incidences of other HPV‐related cancers continue to rise. For the development of effective prevention strategies in high‐risk patients, we aimed to better understand the roles of inflammatory pathways and the tumour microenvironment as the main driver of ...

Surface Brightness Fluctuations in Two SPT Clusters: A Pilot Study

The Astrophysical Journal
Studies of surface brightness fluctuations in the intracluster medium present an indirect probe of turbulent properties such as the turbulent velocities, injection scales, and the slope of the power spectrum of fluctuations toward smaller scales.

A chemical evolution model for galaxy clusters [PDF]

, 2001
We develop a toy-model for the chemical evolution of the intracluster medium, polluted by the galactic winds from elliptical galaxies. The model follows the "galaxy formation history" of cluster galaxies, constrained by the observed luminosity function ...

Buoyancy Instabilities in a Weakly Collisional Intracluster Medium

, 2012
The intracluster medium of galaxy clusters is a weakly collisional, high-beta plasma in which the transport of heat and momentum occurs primarily along magnetic-field lines.

Quasar Feedback on the Intracluster Medium

The Astrophysical Journal, 2002
Galaxy groups are quite underluminous in X-rays compared to clusters, so the intracluster medium (ICM) has to be considerably underdense in the former. We consider this to be due to substantial energy fed back into the ICM when the baryons in the member galaxies condense into stars ending up in supernovae (SNe) or accrete onto central supermassive ...

Intracluster stellar population properties from N-body cosmological simulations -- I. Constraints at $z=0$

, 2003
We use a high resolution collisionless simulation of a Virgo--like cluster in a $\Lambda$CDM cosmology to determine the velocity and clustering properties of the diffuse stellar component in the intracluster region at the present epoch.

Suppression of AGN-driven Turbulence by Magnetic Fields in a Magnetohydrodynamic Model of the Intracluster Medium [PDF]

, 2018
We investigate the role of active galactic nucleus (AGN) feedback in turbulent heating of galaxy clusters. Specifically, we analyze the production of turbulence by g-modes generated by the supersonic expansion and buoyant rise of AGN-driven bubbles ...
