Towards a Dynamic Model of the Kangaroo Knee for Clinical Insights into Human Knee Pathology and Treatment: Establishing a Static Biomechanical Profile

Biomimetics, 2019
There is limited understanding of how patella realignment or patellectomy to surgically manage patellofemoral pain (PFP) affects knee biomechanics. By analysing marsupials like kangaroos that lack an ossified patella, actionable biomimetic insight for ...

Hook tool manufacture in New Caledonian crows : behavioural variation and the influence of raw materials [PDF]

, 2015
Funding: BBSRC grants BB/G023913/1 and BB/G023913/2Background: New Caledonian crows use a range of foraging tools, and are the only non-human species known to craft hooks.

New Caledonian crows attend to multiple functional properties of complex tools [PDF]

, 2013
The ability to attend to the functional properties of foraging tools should affect energy-intake rates, fitness components and ultimately the evolutionary dynamics of tool-related behaviour.

Cognitive processes associated with sequential tool use in New Caledonian crows [PDF]

, 2009
Background: Using tools to act on non-food objects-for example, to make other tools-is considered to be a hallmark of human intelligence, and may have been a crucial step in our evolution.

Experience with Treating Lentigo Maligna with Definitive Radiotherapy

Dermatology Research and Practice, 2018
Lentigo maligna (LM) is a form of melanoma in situ that occurs on exposed, sun-damaged skin; LM can progress to invasive melanoma. Conventional surgical treatment is the preferred management option as it is usually a one-treatment episode and generates a

Population genetic structure and colonisation history of the tool-using New Caledonian crow. [PDF]

PLoS ONE, 2012
New Caledonian crows exhibit considerable variation in tool making between populations. Here, we present the first study of the species' genetic structure over its geographical distribution.
