Time-lapse Very Long Baseline Interferometry Imaging of the Close Active Binary HR 1099

The Astrophysical Journal
We report multiepoch astrometric very long baseline interferometry observations of the chromospherically active binary HR 1099 (V711 Tau, HD 22468) at six epochs over 63 days using the Very Long Baseline Array at 22.2 GHz.

Strategies for Target Identification and Mechanism Elucidation in Phytochemicals

Phytochemicals in Food and Medicine, Volume 1, Issue 3, September 2026.
Strategies for Target Identification of Phytochemicals: Labeling Methods VS. Non‐Labeling Methods ABSTRACT Drug targets serve as the fundamental biological basis through which phytochemicals exert their therapeutic effects, and target discovery represents both the core challenge and the rate‐limiting step in elucidating the mechanisms of action of ...

Multimerization of a rationally designed nanobody for enhanced avidity toward Aβ42 oligomers

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Alzheimer's disease affects tens of millions of people worldwide and is associated with the self‐assembly of the Aβ42 peptide into amyloid aggregates. Among the species formed during this process, soluble oligomeric intermediates are the most closely linked to neurotoxicity and are therefore an attractive target for both therapeutic and ...

Evolution of the Termination Region of the Parsec-scale Jet of 3C 84 Over the Past 20 yr

The Astrophysical Journal
We present the kinematics of the parsec-scale jet in 3C 84 from 2003 November to 2022 June observed with the Very Long Baseline Array at 43 GHz. We find that the C3 component, a bright feature at the termination region of the jet component ejected from ...

Dengue Virus Molecular Targets and Antiviral Drug Development: Advances, Challenges and Therapeutic Perspectives

ChemistrySelect, Volume 11, Issue 33, 1 September 2026.
This narrative review analyzes DENV molecular targets, including structural proteins (C, prM/M, E), non‐structural components (NS1NS5), and host factors, alongside small‐molecule candidates in preclinical and clinical phases. Owing to high structural conservation, the NS2B‐NS3 protease and NS5 (RdRp/MTase) remain primary drug discovery focuses, while ...

VLBA Astrometry of the Galactic Double Neutron Stars PSR J0509+3801 and PSR J1930–1852: A Preliminary Transverse Velocity Distribution of Double Neutron Stars and its Implications

The Astrophysical Journal
The mergers of double neutron star (DNS) systems are believed to drive the majority of short γ -ray bursts (SGRBs), while also serving as production sites of heavy r -process elements.

Obtaining Local‐Tie Vectors From Short‐Baseline Interferometry Between Legacy S/X and VGOS Telescopes at Ny‐Ålesund

Radio Science, Volume 61, Issue 9, September 2026.
Abstract With the ongoing transition for geodetic Very Long Baseline Interferometry (VLBI) from the use of legacy S/X telescopes to the VLBI Global Observing System (VGOS), it is necessary to connect the new VGOS network to the existing legacy S/X telescopes.

Rapid UAV‐ and Ground‐Based Magnetic Mapping of Subsurface Fractures During a Volcano‐Tectonic Crisis in Grindavík, Iceland

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract We applied an integrated UAV‐ and ground‐based magnetometry workflow to map shallow subsurface fractures and cavities in the town of Grindavík during the 2023–2025 volcano‐tectonic crisis. Short‐wavelength linear and semi‐circular magnetic lows delineate open or partially open fractures and localized cavities, including features with no ...
