The Odor Awareness Scale (OAS) is a questionnaire designed to assess individual differences in awareness of odors in the environment. The theory that odor awareness can be distinguished in awareness of negative (to be avoided) odors and positive (to be approached) odors was tested using confirmatory factor analysis (CFA) on the 34-item questionnaire after completion by 525 respondents. CFA (after deletion of 2 items) showed good fit of the 2-factor theory, resulting in a positive awareness subscale (11 items, Cronbach's alpha = .77) and a negative awareness subscale (21 items, Cronbach's alpha = .80). Furthermore, reports of sickness from environmental odors were correlated with the negative odor awareness factor, not the positive odor awareness factor. Respondents scoring high on the overall sum score of the OAS showed significantly better olfactory performance on an odor perception test battery than respondents with a low score. These results suggest a causal relation between awareness of potentially negative odors, olfactory performance and experiencing health effects from environmental odor exposure, that warrants further investigation.

Previous olfactory paired-associate (PA) studies showed that odors are less effective associative cues than other sensory modalities. It has been suggested that odor familiarity might improve memory stability, thereby facilitating PA memory performance. In the current study, we designed three experiments to investigate whether enhanced odor familiarity would also enhance the effectiveness of odors in a PA memory paradigm.

Human exposure to toxic plants is a global concern, with numerous reported cases of accidental poisoning. In this study, a patient experienced poisoning after inadvertently consuming an herbal preparation preserved in alcohol. The patient exhibited characteristic electrocardiogram abnormalities, prompting further investigation into the toxic plant responsible.

Background: As environmental awareness grows, interest in sustainable agriculture is increasing. A promising alternative is the use of plant-beneficial microorganisms such as Trichoderma spp., which suppress pathogens, promote growth and enhance productivity.

However, adoption remains slow, and barriers and drivers influencing their uptake among cocoa farmers across different ecological zones are unclear. Grounded in the Diffusion of Innovations Theory, this study investigated perceptions, drivers, barriers, and strategies to enhance organic pesticide adoption among cocoa farmers in two ecological zones.
