Historical Surveys to Rubin First Look: Absolute Colors of Trans-Neptunian Objects

The Planetary Science Journal
We present a comprehensive photometric study of trans-Neptunian objects (TNOs) by combining data from the Sloan Digital Sky Survey, the Colours of the Outer Solar System Origins Survey, the Dark Energy Survey, and the recent Rubin First Look (RFL) data ...

A Self‐Supervised Framework for Space Object Behaviour Characterisation

Expert Systems, Volume 43, Issue 10, October 2026.
ABSTRACT Foundation Models, which leverage large neural networks pre‐trained on unlabelled data before fine‐tuning for specific tasks, are increasingly being applied to specialised domains. Recent examples include ClimaX for climate and Clay for satellite Earth observation, but a Foundation Model for Space Object Behavioural Analysis (SOBA) has not yet

2019 UO14: A Transient Trojan of Saturn

The Astrophysical Journal Letters
Saturn has long been the only giant planet in our solar system without any known Trojan members. In this Letter, with serendipitous archival observations and refined orbit determination, we report that 2019 UO _14 is a Trojan of the gas giant.

Association Between Serum Homocysteine and Chronic Kidney Disease Severity in Vietnamese Outpatients With Type 2 Diabetes: A Cross‐Sectional Study

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 5, September 2026.
In 201 Vietnamese adults with Type 2 diabetes, higher serum homocysteine was associated with CKD and showed a stronger relationship with filtration markers than with albuminuria. Its discrimination of CKD status was moderate‐to‐good (AUC 0.79), while the 11.35 μmol/L threshold requires external validation.

Subgroups of Adult‐Onset Diabetes: A Prospective Follow‐Up Study of Progression of Insulin Resistance and Deficiency and Association With Liver Steatosis and Fibrosis

Diabetes, Obesity and Metabolism, Volume 28, Issue 9, Page 8004-8015, September 2026.
ABSTRACT Aims To assess progression of insulin deficiency and resistance in diabetes, the stability of cluster‐based subgrouping, and the association between steatotic liver disease (SLD), liver fibrosis (LF), and tissue insulin resistance. Materials and Methods Participants from a regional diabetes register were studied within 3 years from diagnosis ...

The Trojan-like Colors of Low-perihelion Kuiper Belt Objects

The Planetary Science Journal
An important testable prediction of dynamical instability models for the early evolution of the solar system is that Jupiter Trojans share a source population with the Kuiper Belt.

Classification of tau status with machine learning models in amyloid‐positive cohorts

Alzheimer's &Dementia, Volume 22, Issue 8, August 2026.
Abstract INTRODUCTION Although tau positron emission tomography (PET) imaging is effective for staging tau pathology, it is limited clinically by cost and availability. Machine learning models based on magnetic resonance imaging (MRI)– and amyloid PET–derived features may serve as useful screening tools for tau pathology.

Enhanced Liver Fibrosis Test, FIB‐4 and FibroScan: Real‐World Prognostic Accuracy for MASLD in a Biopsy‐Controlled Cohort

Liver International, Volume 46, Issue 8, August 2026.
ABSTRACT Background and Aims Liver fibrosis is a major determinant of liver‐related events (LREs) in patients with metabolic dysfunction‐associated steatotic liver disease (MASLD). Effective stratification based on fibrosis severity is essential for accurate prognosis.

JWST and Gemini Observations of the Active Centaur 450P/LONEOS: Nucleus and Coma Characterizations

The Planetary Science Journal
Between 2019 and 2024, we used the Gemini-N and JWST observatories to conduct a detailed case study of the active Centaur 450P/LONEOS, whose orbit was significantly altered by a close Saturn encounter in 1992.
