Controlling 3D Contractility via Engineered Fibrous Hydrogel Composites
Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.A tunable composite contractile assembly (CCA) is developed that can permit or resist contraction without changing cell‐adhesion and density, unlike collagen whose inherent coupling of these ECM cues limits its use as a platform in contractility studies.

Optical polarization of Active Galactic Nuclei (Review) [PDF]
, 2020 peer reviewedThe optical polarization properties of both low- and high-luminosity active galactic nuclei (AGN) are described, focusing on the origin of the polarization and its relation to the AGN structure, in particular the geometry of the scattering

XRISM Reveals a Remnant Torus in the Low-luminosity AGN M81*
The Astrophysical Journal LettersUp to 40% of galaxies in the local Universe host a low-luminosity active galactic nucleus (LLAGN), making it vital to understand this mode of black hole accretion. However, the presence or absence of Seyfert-like geometries—an accretion disk close to the

On the Subparsec-scale Core Composition of FR 0 Radio Galaxies
The Astrophysical Journal Letters, 2023 Although Fanaroff–Riley type 0 (FR 0) radio galaxies are known to be the most numerous jet population in the local Universe, they are much less explored than the well-established class of FR type I (FR I) and FR type II galaxies due to their intrinsic ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, Volume 36, Issue 27, 2 April 2026.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Quenching Black Hole Accretion by Active Galactic Nuclei Feedback
, 2019 Observations of many dim galactic nuclei in the local universe give good estimations of gas density and temperature at the Bondi radius. If we assume the black hole accretes at the Bondi accretion rate and radiates at the efficiency of a low-luminosity ...

The Effects of Carbonate Precipitation on the Physical Properties of Basalt
AGU Advances, Volume 7, Issue 2, April 2026.Abstract To avoid the negative consequences of climate change, there is an urgent need to remove carbon dioxide from the atmosphere. Carbon mineralization—the conversion of injected CO2 into stable carbonate minerals—offers a promising pathway for large‐scale, permanent geologic storage. While projects such as CarbFix have demonstrated its feasibility,

The Amazon River‐Breeze Circulation Limits Detection of Aerosol‐Cloud Interactions in Warm Clouds
AGU Advances, Volume 7, Issue 2, April 2026.Abstract Increased aerosol concentrations can brighten low‐level clouds and extend their lifetimes, but aerosol–cloud interactions (ACI) remain highly uncertain and difficult to quantify. We show that part of this uncertainty is caused by topographical influences on clouds, that is, those arising from land–water contrasts.
