Amphisbaenian Head Movement And Burrowing Forces In Damp Granular Media, Jacob Newell

Damp granular media is a difficult environment to study because it is both practically complex and it lacks equations which fully describe its behavior. In this study, an oscillatory lateral head movement and its effects while penetrating damp granular media were tested using a robophysical model. This experimental research was inspired by the burrowing behavior of the clade Amphisbaenia, a group of usually limbless squamates that employ a variety of different burrowing behaviors, but it can apply to a wide range of burrowers. This research could help with both human burrowing technologies and the further investigation of animal behaviors.

Scales from adult zebrafish, Danio rerio, are an established model for studying osteoblast and osteoclast activity. In this study, scales in a cell culture were used to determine if the hormone leptin has an effect on activity of these bone remodeling scales. Alkaline phosphatase (ALP) and tartrate-resistant acid phosphatase (TRAP) activities of zebrafish scales were measured and compared with and without leptin treatment. There was no statistically significant difference between leptin treatments in terms of ALP and TRAP activity. Differences between TRAP values between days 1 and 2 did look promising although they were not statistically significant. This study …
