A Comprehensive Review of Tire Abrasion: Mechanisms, Parameters, and Wear Rates in the Era of Vehicle Electrification

Applied Research, Volume 5, Issue 4, August 2026.
The type of vehicle (internal combustion, hybrid, electric) has a direct effect on its tire wear particle emission. As expected, electric vehicles generate higher amounts due to their higher weight and torque, but regenerative breaking must also be accounted for.

Endothelial-to-mesenchymal transition derived fibronectin mediates pulmonary fibrosis in mice following chronic exposure to ozone-oxidized 6PPD

Ecotoxicology and Environmental Safety
The release of N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylene-diamine (6PPD) and its environmental transformation products poses a significant respiratory health risk. While 6PPD-quinone has been widely studied, the toxicological profiles of other oxidation

Maternal and infant gut microbiome

iMeta, Volume 5, Issue 4, August 2026.
The maternal–infant continuum involves critical windows of host–microbiota co‐adaptation. Preconception, maternal and paternal microbiomes modulate immunity and reproduction. During pregnancy, a gut–placenta axis emerges, where microbial metabolites influence fetal growth or contribute to complications like gestational diabetes mellitus (GDM ...

The Effects of Microplastics and Additives on Ecosystem Function, Structure, and Signaling

Global Change Biology, Volume 32, Issue 8, August 2026.
Microplastics disrupt ecosystem signaling through olfactory traps, altering predator–prey signaling and disrupting microbial communication and quorum sensing. ABSTRACT Microplastics (MPs) and their associated chemical additives are pervasive contaminants whose ecological impacts extend beyond organismal toxicity to fundamentally alter ecosystem ...

Positive Doping Test Linked to Crumb Rubber From Artificial Football Pitch: Case Report

Drug Testing and Analysis, Volume 18, Issue 6, Page 719-724, June 2026.
1,3‐DMBA was detected in urine samples of eight athletes following a doping control, resulting in one AAF and levels below WADA's MRL in seven teammates. Investigation revealed contamination from rubber infill used on the indoor artificial turf, with analysis confirming 1,3‐DMBA in the turf's crumb rubber originating from recycled tires.
