Feeding is a complex process that involves an integrated response of multiple functional systems. Animals evolve phenotypic integration of complex morphological traits to covary and maximize performance of feeding behaviors. Specialization, such as feeding on dangerous prey, can further shape the integration of behavior and morphology as traits are expected to evolve and maintain function in parallel.

Their relatively small sample sizes, long growth periods, and difficulties distinguishing the sexes of fossil specimens mean that there are little compelling data on dimorphism in these animals. The extant gharial () is a large and endangered crocodylian that is sexually dimorphic in size, but males also possesses a sexually selected structure, the ghara, which has an osteological correlate in the presence of a fossa associated with the nares.

- The study explored the use of high-intensity stepping training in various contexts for individuals with incomplete spinal cord injury (iSCI) to see if it could improve their mobility and overall fitness, similar to previous findings in post-stroke patients.
- Four individuals with iSCI participated in up to 40 one-hour training sessions over a few months, tracking their tolerance and performance during the exercises.
- While the training was generally feasible and participants experienced some improvements in locomotor function, the overall gains were modest, suggesting this method may have limited effectiveness for those with more significant impairments.
Over a half million new cases of Head and Neck Squamous Cell Carcinoma (HNSCC) are diagnosed annually worldwide, however, 5 year overall survival is only 50% for HNSCC patients. Recently, high throughput technologies have accelerated the genome-wide characterization of HNSCC. However, comprehensive pipelines with statistical algorithms that account for HNSCC biology and perform independent confirmatory and functional validation of candidates are needed to identify the most biologically relevant genes.
