A Look at Eight Outbursts of Comet 7P/Pons–Winnecke

open access: yesThe Planetary Science Journal
Cometary outbursts may be used as a means to infer the physical processes occurring on cometary nuclei. To that end, we studied eight outbursts of comet 7P/Pons–Winnecke identified between 2021 June 3 and August 31. The data analyzed consisted of optical

First Assessment of Genetic Damage in the Speckled Cockroach (Nauphoeta cinerea) After Consumption of Lettuce (Lactuca sativa) Cultivated and Commercialized in Northeastern, Brazil

open access: yesEnvironmental Toxicology, Volume 41, Issue 9, Page 682-689, September 2026.
ABSTRACT This study reports, for the first time, the use of the speckled cockroach Nauphoeta cinerea as a promising bioindicator for genotoxic monitoring. It was validated through control groups (both positive and negative) in addition to testing lettuce (Lactuca sativa ) samples from public street markets consumed by N. cinerea specimens in Pernambuco,

Mapping the Crustal Thickness of the Andes Using pmP Phases Identified From Adaptive Teleseismic Array Data

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Crustal thickness (or Moho depth) is a key parameter for many geological and geophysical models. Despite this we have a limited number of measurements, typically from seismic receiver functions, to constrain variations in crustal thickness.

Ferric Chloride: The Venusian Unknown UV Absorber?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Near‐ultraviolet imaging of the planet Venus reveals inhomogeneous absorption features in the otherwise bright clouds. This absorption has been studied for nearly 100 years, but identification of the near‐UV absorber remains one of the largest open questions in Venusian research.

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

Investigating Local- and Global-scale Dust Redistribution on Comet 67P/Churyumov–Gerasimenko

open access: yesThe Planetary Science Journal
We use a 3D dynamical Monte Carlo model to simulate the trajectories of individual dust grains and map their redeposition across the surface of comet 67P/Churyumov–Gerasimenko.
