Article Synopsis
- Many ant species possess chemical defenses, but their effects on the nervous system remain poorly understood.
- Research showed that various ant strains respond to chemical extracts from the invasive Argentine Ant, and a specific ion channel is necessary for this response.
- Conducted in an undergraduate lab course, the study demonstrated that chemotaxis assays can yield valuable research experiences and enhance understanding of interactions between different ant species.
Tadpoles display preferences for different environments but the sensory modalities that govern these choices are not well understood. Here, we examined light preferences and associated sensory mechanisms of albino and wild-type tadpoles. We found that albino tadpoles spent more time in darker environments compared to the wild type, although they showed no differences in overall activity.

Objective: A description is presented on the overall incidence and age group incidence, the delay in the diagnosis, and main outcomes.
