Understanding extracellular vesicles in antiaging

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Cellular Responses to Tartrazine and Sulfanilic Acid Exposure in BEAS‐2B Cells: Viability, Apoptosis, and DNA Damage

open access: yesJournal of Applied Toxicology, Volume 46, Issue 10, Page 3446-3454, October 2026.
ABSTRACT Tartrazine is a synthetic azo dye widely used in food, pharmaceutical, and cosmetic products, resulting in extensive human exposure, while its toxicity and that of its primary metabolite, sulfanilic acid, remain controversial. Considering the reported association of tartrazine with hypersensitivity and allergic‐like reactions, human bronchial ...

Postperihelion Cometary Activity on the Outer Main-belt Asteroid 2005 XR132

open access: yesThe Planetary Science Journal
We report comet-like activity on the outer main-belt asteroid 2005 XR _132 discovered by the Lulin One-meter Telescope in early 2021 April. A series of follow-up observations were triggered to characterize the morphology and brightness variation of 2005 ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Lunar Dayside Surface Potentials in the Terrestrial Magnetotail Inferred From Comparing Observed and Modeled Photoelectrons

open access: yesGeophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract As an airless body, the lunar surface is charged as a result of balancing electric currents into and away from the surface. Lunar surface charging is important for both scientific and human‐exploration purposes. The nightside surface charging has been well characterized by previous studies, but less so for the dayside.

Detection of Synchronic Bands in the Dust Tail of Comet C/Hale-Bopp 1995 O1 [PDF]

open access: yesPublications of the Astronomical Society of Japan, 1997
An imaging observation of the dust tail of Comet C/Hale-Bopp 1995O1 was carried out from 1997 March 5 through 9, using a wide-field CCD imaging camera. We detected several striae of degree scale in the dust tail, which could be recognized for the whole observed period.

Recent Advances in Ferrite‐Based Materials for Biomedical Applications: A Comprehensive Review

open access: yesAdvanced Materials, Volume 38, Issue 48, 26 August 2026.
Ferrite nanoplatforms are presented as tunable biomedical materials in which synthesis control, cation engineering, defect/morphology regulation, and surface functionalization govern structure–property–bioactivity relationships. These design strategies enable multifunctional applications including MRI contrast, magnetic hyperthermia, targeted drug ...
