pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, Volume 600, Issue 13, Page 1859-1871, July 2026.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

CTP Ontology: A Semantic Model for Structuring Cultural Thematic Paths

open access: yesJournal of the Association for Information Science and Technology, Volume 77, Issue 7, Page 979-1010, July 2026.
Abstract A thematic path enhances the appreciation of cultural heritage by connecting diverse cultural objects through shared themes. This study introduces the Cultural Thematic Path (CTP) Ontology, designed to support the creation, organization, description, publication, and management of thematic paths within the GLAM (Galleries, Libraries, Archives,

High Early Embryo Mortality and Low Hatching Success Observed in Aldabra Giant Tortoise Populations

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
This preliminary study provides the first population‐level assessment of fertilisation and hatching success in the Aldabra giant tortoise across natural and translocated populations in Seychelles, revealing low and highly variable hatching success—particularly in translocated populations.

Genotype‐Dependent Variations in Egg Quality and Nutritional Composition of Thermotolerant Chickens Under Hot‐Climate Conditions

open access: yesFood Science &Nutrition, Volume 14, Issue 7, July 2026.
Hot‐climate conditions revealed clear genotype‐dependent differences in egg quality and nutritional composition among Fayoumi, Naked Neck, and Frizzled hens. These thermotolerant genotypes showed distinct amino acid, lipid, omega‐3, and iron profiles, supporting climate‐resilient poultry production.

Annealing‐Induced Modifications in Yam Starches: Implications for Fermented Yam Flour (Elubo) and Textural Quality of Named Indigenous Yam Food Product—Amala

open access: yesFood Science &Nutrition, Volume 14, Issue 7, July 2026.
Processing yam tubers into elubo (fermented yam flour) induces starch annealing, which modifies starch functionality and pasting behavior. These changes significantly influence the textural quality of amala prepared from 55 varieties of two Dioscorea species (D. alata and D. rotundata).
