Characterizing molecular underpinnings of plastic traits and balanced polymorphisms represent two important goals of evolutionary biology. Fire ant gynes (pre-reproductive queens) provide an ideal system to study potential links between these phenomena because they exhibit both supergene-mediated polymorphism and nutritional plasticity in weight and colony-founding behavior. Gynes with the inversion supergene haplotype are lightweight and depend on existing workers to initiate reproduction.

Machine learning (ML) has previously been used to dissect some of the heterogeneity in COPD. The widespread adoption of electronic health records (EHRs) has led to the rapid accumulation of large amounts of patient data as part of routine clinical care.

During a survey for Sarcocystis in wild canids, a single worm matching the morphology of encapsulated Trichinella was observed in a muscle tissue squash from a gray fox male originating from Pennsylvania. The worm was photographed and then separated from the host tissue by artificial digestion, and genomic DNA was extracted from the worm.
