Food Contamination and Safety in Nigeria: A Systematic Synthesis of Heavy Metals, Microbial Pathogens, and Health Risk Metrics

open access: yesFood Safety and Health, EarlyView.
This is an infographic driver of food contaminants and health effects. ABSTRACT Food safety remains a critical challenge in Nigeria due to rapid urbanization and weak regulatory enforcement. This systematic review synthesizes empirical evidence from 2015 to 2025 to characterize food contaminant profiles and associated human health risks in Nigeria ...

Modeling the Radial Distribution of Pulsars in the Galaxy

open access: yesThe Astrophysical Journal Letters
The Parkes 20 cm multibeam pulsar surveys have discovered nearly half of the known pulsars and revealed many distant pulsars with high dispersion measures.

Dust distribution in the Milky Way disk

open access: yes, 2019
To study the Galactic disk structure, we use the combination of the near-infrared survey 2MASS and Gaia DR2. We develop the Field Extinction - Distance Relation Deconvolver (FEDReD) algorithm to unravel distance and extinction. It is a Bayesian deconvolution algorithm which works field of view by field of view.

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Radial Wave in the Galactic Disk: New Clues to Discriminate Different Perturbations

open access: yesThe Astrophysical Journal
Decoding the key dynamical processes that shape the Galactic disk structure is crucial for reconstructing the Milky Way’s evolution history. The second Gaia data release unveils a novel wave pattern in the L _Z −〈 V _R 〉 space, but its formation ...

Tannic Acid Mitigates Monosodium Glutamate‐Induced Cortical Damage by Modulating Synaptic and Calcium‐Related Gene and Protein Expression

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Neurotoxicity induced by excessive glutamatergic signaling is associated with synaptic dysfunction, calcium imbalance, and oxidative stress, which are key molecular events implicated in several neurodegenerative conditions. Monosodium glutamate (MSG), a common flavor enhancer, may exert neurotoxic effects, particularly on synaptic integrity ...

Early Coformation of the Milky Way’s Thin and Thick Disks at Redshift z > 2

open access: yesThe Astrophysical Journal
The Milky Way serves as a template for understanding the formation and evolution of late-type massive disk galaxies since we can obtain detailed chemical and kinematic information for large samples of individual stars. However, the early formation of the
