Humidity determines penetrance of a latitudinal gradient in genetic selection on the microbiota by .

Unlabelled: The fruit fly is a model for understanding how hosts and their microbial partners interact as the host adapts to wild environments. These interactions are readily interrogated because of the low taxonomic and numeric complexity of the flies' bacterial communities. Previous work has established that host genotype, the environment, diet, and interspecies microbial interactions can all influence host fitness and microbiota composition, but the specific processes and characters mediating these processes are incompletely understood.

Telecytopathology for immediate evaluation of fine-needle aspiration specimens.

Background: On-site evaluation of fine-needle aspiration (FNA) specimens by a pathologist is essential to obtain adequate samples and provide a preliminary diagnosis. Distance from the laboratory can make this difficult. The authors present their experience with on-site evaluation using telecytopathology.
