Honey bees rely on associative stimulus strength after training on an olfactory transitive inference task.

Transitive inference, the ability to establish hierarchical relationships between stimuli, is typically tested by training with premise pairs (e.g., A + B-, B + C-, C + D-, D + E-), which establishes a stimulus hierarchy (A > B > C > D > E).

Association of obesity and metabolic syndrome with incident primary open angle glaucoma in the UK Biobank.

Background: We sought to investigate the association between obesity, metabolic syndrome, and metabolic health with incident primary open-angle glaucoma (POAG).

Methods: We included 103 249 UK Biobank participants without previously diagnosed glaucoma or glaucoma-related procedures at enrolment. The primary outcome was POAG identified from diagnostic coding via linked hospital inpatient and primary care data.
