Formation of Condition‐Dependent Alpha‐Synuclein Fibril Strain in Artificial Cerebrospinal Fluid

Advanced Science, Volume 13, Issue 7, 3 February 2026.
α‐synuclein aggregation in artificial cerebrospinal fluid (aCSF) leads to a distinct conformation with an electron density pocket motif found in aggregates from PD and MSA patients. Such fibrils has low stability outside the reaction conditions, hinting about the influence of cerebrospinal fluid components not only on the formation, but also on the ...

HST Confirms Sub-5 kpc Dual Quasar Pairs at Cosmic Noon

The Astrophysical Journal
During cosmic noon ( z ∼ 1–3), when both star formation and black hole growth peaked, galaxy mergers are predicted to trigger dual active galactic nuclei that eventually coalesce as supermassive black hole (SMBH) binaries.

Epstein‐Barr Virus Expressed Long Non‐Coding RNA (lncBARTs) Regulate EBV Latent Genome Replication

Advanced Science, Volume 13, Issue 8, 9 February 2026.
EBV produces abundant level of lncBARTs, which are essential for maintaining viral genome replication in EBV‐associated cancers. LncBARTs interact with a complex comprising BRD4, CTCF and viral protein EBNA1 at EBV oriP region. This interaction tethers oriP to host chromosomes, facilitating EBV episome replication.

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.

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 ...

Superluminal motion in the double-lobed quasar 3C 245

The Astrophysical Journal, 1987
VLBI observations of 3C 245 obtained at 10.7 GHz with the Mark III array at five epochs in 1981-1986 are reported. The data-reduction and model-fitting procedures are explained, and the results are presented in tables, graphs, and maps along with previously published data on 11 other superluminal sources. The central component of the quasar is found to

Minor Contribution of Quasars to Ionizing Photon Budget at z ∼ 6: Update on Quasar Luminosity Function at the Faint End with Subaru/Suprime-Cam [PDF]

, 2017
We constrain the quasar contribution to the cosmic reionization based on our deep optical survey of z ∼ 6 quasars down to zR = 24.15 using Subaru/Suprime-Cam in three UKIDSS-DXS fields covering 6.5 deg2. In Kashikawa et al.

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 ...

Localized Energy Absorption through LaB6 Surface Modification of PA12 Enables Enhanced Tensile Performance in Diode Laser PBF‐LB

Chemistry–Methods, Volume 5, Issue 12, November 2025.
LaB6 surface modification of PA12 enables efficient NIR diode laser PBF‐LB processing, with enhanced tensile strength and tailored microstructures achieved at minimal additionaly energy. By reducing the need for high filler content, this approach expands the options and performance levels of advanced industrial‐grade polymer additive manufacturing. The
