Engineered 3D Fibronectin‐Based Environments Modulate the Pathogenic Profile of Arthritic Synovial Fibroblasts

open access: yesAdvanced NanoBiomed Research, EarlyView.
Fibroblast behavior is shaped by the surrounding microenvironment, yet conventional culture systems often fail to capture disease‐relevant phenotypes. Here, platform‐dependent responses of healthy and arthritic synovial fibroblasts are examined across 2D and 3D culture systems. Distinct inflammatory and proliferative signatures emerge, highlighting how

The Next Generation Deep Extragalactic Exploratory Public (NGDEEP) Survey

open access: yesThe Astrophysical Journal Letters
We present the Next Generation Deep Extragalactic Exploratory Public (NGDEEP) Survey, a deep slitless spectroscopic and imaging Cycle 1 JWST treasury survey designed to constrain feedback mechanisms in low-mass galaxies across cosmic time. NGDEEP targets

A High-precision Survey of the D/H Ratio in the Nearby Interstellar Medium

open access: yesThe Astrophysical Journal, 2023
We present high signal-to-noise ratio measurements of the H i Ly α absorption line toward 16 Galactic targets that are at distances between approximately 190 and 2200 pc, all beyond the wall of the Local Bubble.

Effects of Dietary Mannan Oligosaccharides on Growth, Disease Resistance, and Gut Microbiota in Zebrafish

open access: yesAnimal Research and One Health, EarlyView.
Supplementation with mannan oligosaccharides (MOS) enhances growth, disease resistance, antioxidant capacity, and gut microbiota diversity while suppressing inflammation, apoptosis, and strengthening intestinal barrier integrity in zebrafish challenged with LPS or DSS.

Strong He i Emission Lines in High N/O Galaxies at z ∼ 6 Identified in JWST Spectra: High He/H Abundance Ratios or High Electron Densities?

open access: yesThe Astrophysical Journal
We present He i /H β flux and He/H abundance ratios in three James Webb Space Telescope galaxies with significant constraints on N/O abundance ratios, GS-NDG-9422, RXCJ2248-ID, and GLASS150008 at z ∼ 6 mostly with the spectroscopic coverage from He i λ ...

The Bochum Survey of the Southern Galactic Disk: IV. Multi‐Band Photometry

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°‐wide stripe in the southern galactic disk from September 2010 to September 2019.

Modeling the Ages and Chemical Abundances of Elliptical Galaxies

open access: yesThe Astrophysical Journal
Spectroscopic studies of elliptical galaxies show that their stellar population ages, mean metallicity, and α enhancement traced by [Mg/Fe] all increase with galaxy stellar mass or velocity dispersion.

The Disrupted Chemical Enrichment History of the Milky Way Driven by Gas Accretion

open access: yesThe Astrophysical Journal Letters
As the only galaxy enabling temporally resolved observations from an internal vantage point, the Milky Way as a galaxy offers unique insights into galactic chemical enrichment history, establishment of fundamental scaling relations, and the underlying ...

Artificial intelligence‐driven bioinformatics: From analytical pipelines to model‐centered biological discovery

open access: yesiMetaOmics, EarlyView.
AI‐driven bioinformatics is best viewed as an emerging model‐centered discovery framework in which learned representations increasingly support prediction, intervention design, and workflow orchestration, while classical pipelines remain essential for validation and reproducibility.

Stellar Populations with MaNGA: Iron Kink and Nitrogen Fuzz

open access: yesThe Astrophysical Journal
Recent analysis of 2968 MaNGA early-type galaxies has yielded two notable trends with velocity dispersion ( σ ) not previously discussed in the literature. First, Fe abundance rises with σ but only until σ  ≈ 100 km s ^−1 , after which it falls.
