Reduced accrual of mineral-associated organic matter after two years of enhanced rock weathering in cropland soils, though no net losses of soil organic carbon

This study evaluates the impact of enhanced rock weathering on soil organic matter pools over two years, finding reduced mineral-associated organic matter accrual without net losses of soil organic carbon.

Tick extracellular vesicles alter keratinocyte function in the skin epidermis

This study shows that tick extracellular vesicles alter keratinocyte function in the epidermis by inhibiting proliferation and wound closure, linked to phosphoinositide 3-kinase, KGF-1, and TGF-β.

Tick hemocytes have pleiotropic roles in microbial infection and arthropod fitness

This study identifies hemocyte heterogeneity and pleiotropic roles in ticks using multi-omics approaches, revealing their impact on immunity, metabolism, and arthropod fitness.

Metabolic disruption impacts tick fitness and microbial relationships

This study shows that metabolic changes in ticks affect their fitness and interactions with microbes, highlighting the role of BAIBA in these relationships.

Post-translational modification by the Pgf glycosylation machinery modulates Streptococcus mutans physiology and virulence

This study shows that the Pgf glycosylation machinery in Streptococcus mutans modifies surface proteins, affecting biofilm formation and virulence, with phosphorylation compensating for glycosylation loss.

CD36 homologs determine microbial resistance to the Lyme disease spirochete

The paper identifies CD36 homologs as conserved lipid receptors mediating anti-Borrelia immunity in both ticks and humans.

Amyloid aggregation of Streptococcus mutans Cnm influences its collagen-binding activity

This study shows that Cnm, a collagen-binding protein in S. mutans, forms amyloids that lose collagen-binding activity, modulating biofilm function.
