Journal of Peptide Science, Volume 32, Issue 8, August 2026.Cementum attachment protein‐derived peptides adsorb to specific crystallographic faces of brushite and calcium oxalate, blocking calcium deposition. This phosphorylation‐enhanced modulation alters crystal growth under conditions in vitro, leading to the formation of irregular brushite crystals and rosette‐like calcium oxalate morphologies.

Environmental Toxicology, Volume 41, Issue 8, Page 537-548, August 2026.ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

Space Weather, Volume 24, Issue 8, August 2026.Abstract The period from 1 to 14 May 2024 was marked by some of the most intense solar activity of Solar Cycle 25, including multiple X‐class flares, fast coronal mass ejections (CMEs), and diverse solar radio emissions. We present observations from the Mexican e‐Callisto network (REC‐Mx), including long‐duration continuum emissions (CTMs), Type II ...

Global patterns and processes of establishment risk by non‐indigenous marine fish
Journal of Applied Ecology, Volume 63, Issue 8, August 2026.Niche overlap may be critical to consider, even in areas that appear environmentally unsuitable or poorly connected for NIS. Preserving the intrinsic biotic resistance posed by native species can improve the effectiveness of targeted conservation measures.

British Journal of Pharmacology, Volume 183, Issue 15, Page 4227-4245, August 2026.Background and Purpose α‐Synucleinopathies are neurodegenerative disorders characterized by the aggregation and propagation of misfolded α‐synuclein. In Parkinson's disease (PD), the most common α‐synucleinopathy, the progression of motor and nonmotor deficits, and dopaminergic neuron loss, are closely linked to the spreading of misfolded α‐synuclein ...

Habitat loss and fragmentation for an old‐forest species is driven by severe wildfire and drought
Conservation Science and Practice, Volume 8, Issue 8, August 2026.We examined the long‐term trends in habitat for California spotted owls and attributed habitat changes to specific drivers. We found that the 43% decline in habitat from 1985 to 2022 could primarily be attributed to wildfire and drought. Habitat patches also became smaller and more isolated over time.
