Work minimization accounts for footfall phasing in slow quadrupedal gaits (2017)
Journal Article
Usherwood, J. R., & Self Davies, Z. T. (2017). Work minimization accounts for footfall phasing in slow quadrupedal gaits. eLife, 6, e29495. https://doi.org/10.7554/eLife.29495.001

Quadrupeds, like most bipeds, tend to walk with an even left/right footfall timing. However, the phasing between hind and forelimbs shows considerable variation. Here, we account for this variation by modeling and explaining the influence of hind-for... Read More about Work minimization accounts for footfall phasing in slow quadrupedal gaits.

Sost deficiency does not alter bone’s lacunar or vascular porosity in mice (2017)
Journal Article
Mosey, H., Núñez, J. A., Goring, A., Clarkin, C. E., Staines, K. A., Lee, P. D., Pitsillides, A. A., & Javaheri, B. (2017). Sost deficiency does not alter bone’s lacunar or vascular porosity in mice. Frontiers in Materials, 4(27), https://doi.org/10.3389/fmats.2017.00027

SCLEROSTIN (Sost) is expressed predominantly in osteocytes acting as a negative regulator of bone formation. In humans, mutations in the SOST gene lead to skeletal overgrowth and increased bone mineral density, suggesting that SCLEROSTIN is a key reg...

Elastin is Localised to the Interfascicular Matrix of Energy Storing Tendons and Becomes Increasingly Disorganised With Ageing (2017)
Journal Article
Godinho, M. S., Thorpe, C. T., Greenwald, S. E., & Screen, H. R. (2017). Elastin is Localised to the Interfascicular Matrix of Energy Storing Tendons and Becomes Increasingly Disorganised With Ageing. https://doi.org/10.1038/s41598-017-09995-4

Tendon is composed of fascicles bound together by the interfascicular matrix (IFM). Energy storing tendons are more elastic and extensible than positional tendons; behaviour provided by specialisation of the IFM to enable repeated interfascicular sli...

Centre of mass is a fundamental anatomical and biomechanical parameter. Knowledge of centre of mass is essential to inform studies investigating locomotion and other behaviours, through its implications for segment movements, and on whole body factor...

Morphological modularity arises in complex living beings due to a semi-independent inheritance, development, and function of body parts. Modularity helps us to understand the evolvability and plasticity of organismal form, and how morphological varia... Read More about In search of morphological modules: a systematic review.

A distinctive patchy osteomalacia characterises Phospho1-deficient mice (2017)
Journal Article

The phosphatase PHOSPHO1 is involved in the initiation of biomineralisation. Bones in Phospho1 knockout (KO) mice show histological osteomalacia with frequent bowing of long bones and spontaneous fractures: they contain less mineral, with smaller min...

How extinct, non-avian theropod dinosaurs locomoted is a subject of considerable interest, as is the manner in which it evolved on the line leading to birds. Fossil footprints provide the most direct evidence for answering these questions. In this st...

Gearing effects of the patella (knee extensor muscle sesamoid) of the helmeted guineafowl during terrestrial locomotion (2017)
Journal Article

Human patellae (kneecaps) are thought to act as gears, altering the mechanical advantage of knee extensor muscles during running. Similar sesamoids have evolved in the knee extensor tendon independently in birds, but it is unknown if these also affec...

Aggressive encounters may have important life history consequences due to the potential for injury and death, disease transmission, dispersal opportunities or exclusion from key areas of the home range. Despite this, little is known of their detailed... Read More about Dynamics of direct inter-pack encounters in endangered African wild dogs.

Morphology and the gradient of a symmetric potential predicts gait transitions of dogs (2017)
Journal Article

Gaits and gait transitions play a central role in the movement of animals. Symmetry is thought to govern the structure of the nervous system, and constrain the limb motions of quadrupeds. We quantify the symmetry of dog gaits with respect to combinat... Read More about Morphology and the gradient of a symmetric potential predicts gait transitions of dogs.
