- Archerfish use their shooting technique to produce adaptive underwater jets
Summary: Archerfish use the same mouth opening maneuver to produce and to adapt aerial and underwater jets.
- Longitudinal and transversal displacements between triceps surae muscles during locomotion of the rat
Summary: Differences in anatomy, morphology and neural drive between rat ankle plantar-flexors cause substantial intermuscular displacement during locomotion, which may affect mechanical interactions between muscle bellies and tendons.
- How the bending kinematics of swimming lampreys build negative pressure fields for suction thrust
Highlighted Article: A comparison of the swimming and hydrodynamics of control lampreys to lampreys whose spinal cord was transected mid-body reveals the hydrodynamic advantage of actively controlled swimming.
- Validation of XMALab software for marker-based XROMM
Summary: New motion analysis software offers greater precision and reproducibility than existing tools for tracking markers in videos, yielding greater sensitivity for measuring 3D motions with XROMM animations.
- Bristles reduce the force required to ‘fling’ wings apart in the smallest insects
- Preferred gait and walk–run transition speeds in ostriches measured using GPS-IMU sensors
- Determinants of preferred ground clearance during swing phase of human walking
Summary: The foot's ground clearance during each swing phase of walking may be explained by competing costs of lifting the foot versus scuffing it on the ground, modulated by movement variability.
- Flowing water affects fish fast-starts: escape performance of the Hawaiian stream goby, Sicyopterus stimpsoni
Summary: Fast-start escape trials conducted in flow tanks indicate that fish heading into flow frequently fail to respond when attacked frontally, potentially because mechanical stimuli are masked by flowing water.
