Overcoming PEG Antigenicity: Statistical PEG Isomers Reduce Antibody Binding

Advanced Science, Volume 13, Issue 7, 3 February 2026.
Conventional poly(ethylene glycol) (PEG) is commonly applied in biomedicine, but is now known to induce antibody formation. Here, it is shown that the development of “randomized PEG” (rPEG) featuring glycidyl methyl ether (GME) comonomers decreased antibody binding.

A Deep Chandra X-Ray Survey of a Luminous Quasar Sample at z ∼ 7

The Astrophysical Journal
We present new Chandra observations of seven luminous quasars at z > 6.5. Combined with archival Chandra observations of all other known quasars, they form nearly complete X-ray observations of all currently known z ∼ 7 quasars with M _1450 < –26.5 ...

The Marriage of Metal Nanoclusters With Reticular Frameworks: Synthetic Strategies and Biomedical Applications

Aggregate, Volume 7, Issue 2, February 2026.
The integration of metal nanoclusters (MNCs) with reticular frameworks (RFs) has recently emerged as a powerful strategy to create composite materials with enhanced and synergistic functionalities. This review provides an overview of the synthetic strategies developed for constructing MNCs/RFs composites and their recent advances in biomedical ...

VODKA-JWST: Synchronized Growth of Two Supermassive Black Holes in a Massive Gas Disk? A 3.8 kpc Separation Dual Quasar at Cosmic Noon with the NIRSpec Integral Field Unit

The Astrophysical Journal
The search for dual supermassive black holes (SMBHs) is of immense interest in modern astrophysics. Galaxy mergers may fuel and produce SMBH pairs. Actively accreting SMBH pairs are observed as dual quasars, which are vital probes of SMBH growth.

The Study of the Circumgalactic Medium with Quasar Pairs

The Astrophysical Journal Supplement Series, 2023
We have collected 10,025 foreground–background quasar pairs with projected distances d _p < 500 kpc from the large quasar catalog of the Sloan Digital Sky Survey DR16Q. We investigate the properties of the Mg ii absorption lines with W _r > 0.15 Å around

Characterization of a deformable beating cardiac phantom with real‐time dosimetric capabilities for validation of MRI‐guided heart radiotherapy

Medical Physics, Volume 53, Issue 2, February 2026.
Abstract Background Stereotactic arrhythmia radioablation (STAR) has emerged as a salvage treatment for patients with ventricular tachycardia, and the MR‐linacs offer MRI‐guidance during such treatment. However, available workflows on MR‐linacs are not yet optimized and characterized dedicatedly to perform heart radiotherapy due to a lack of realistic ...

SARS‐CoV‐2 Chronic Intervillositis: Variations of Maternal Antiviral Response

American Journal of Reproductive Immunology, Volume 95, Issue 2, February 2026.
ABSTRACT Problem Placental compromise is a determining factor in the outcome of pregnancies complicated by maternal SARS‐CoV‐2 infection. Chronic histiocytic intervillositis (CHI) is the initial response to SARS‐CoV‐2 infection, but the underlying mechanisms are poorly understood.

Impact of tumor motion on target delineation and dose calculation accuracy using rapid‐acquisition HyperSight CBCT in online adaptive radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background HyperSight CBCT offers rapid image acquisition and enhanced image quality, supporting its integration into online adaptive radiotherapy (OART). However, its performance under respiratory‐induced tumor motion requires further evaluation.

Commissioning and robustness evaluation of external laser sensor for respiratory gating in carbon‐ion radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background Respiratory‐induced tumor motion remains a significant challenge in carbon‐ion radiotherapy (CIRT), potentially compromising dose accuracy and escalating dose in nearby organs. Although belt‐based sensors are commonly used for gating, issues related to setup reproducibility and patient comfort increased the demand for laser‐based ...
