Boylan Biomechanics Video
The butterfly position is the cornerstone of modern ice hockey goaltending. However, many have questioned if it is the cause of increasing non-contact goalie hip and groin injuries. In this Notre Dame Biomechanics in The Wild video, we investigate if the butterfly method is to blame.

This video describes how mountain goats can influence robot design based on the biomechanical principles that influence their impeccable balance. It explains how a mountain goat's center of mass, controlled limb force generation, and specialized hoof anatomy can all be mimicked in robotics and why it is relevant.

The Dracula Ant or Mystrium Camillae is the fastest animal in the world thanks to its spring loaded snap which travels over 200 miles per hour or 90 meters per second. In this video we briefly explore how this is possible.

Allometry and different constraints on the size of land and sea mammals are discussed in this video. A brief explanation of allometry as well as thermoregulation in sea mammals is described in the video. Information in the video was taken from and be further extrapolated from the following sources: Biomechanical Consequences of Scaling by Andrew A. Biewener Biomechanics and Energetics in Aquati...

(Invited talk for Session X23: Morphogenesis) Between individuals and across species, brain morphology is strikingly consistent in some significant ways. One example is a characteristic pattern of cortical thickness in gyrencephalic, or folded, brains - thick outer folds, or gyri, and thin inner folds, or sulci. This raises the question: which factors (genetic, biochemical, physical, and/or oth...
