Origin of jaws - the greatest unsolved mystery of early vertebrate evolution. The 2008 discovery of an unborn embryo in the 380 million-year-old "Mother Fish" from the famous Gogo fossil deposit in NW Australia has attracted a collaboration of Australian, American and Chinese scientists to a new international collaboration. The team will study spectacular new fossils from central Australia and southern China, the oldest known back-boned animals with jaws and a hard skeleton. Innovative 3D X-ray ....Origin of jaws - the greatest unsolved mystery of early vertebrate evolution. The 2008 discovery of an unborn embryo in the 380 million-year-old "Mother Fish" from the famous Gogo fossil deposit in NW Australia has attracted a collaboration of Australian, American and Chinese scientists to a new international collaboration. The team will study spectacular new fossils from central Australia and southern China, the oldest known back-boned animals with jaws and a hard skeleton. Innovative 3D X-ray computer tomography, and the Australian synchrotron, will be used to investigate ancient cells and preserved soft tissue structures, to search for evidence that copulation and internal fertilization, as in modern mammals, might have originated when jaws first evolved.

Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the fi ....Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the final finish is achieved. We will research this technique for application to unique Australian heritage materials that are important to the specific conservation needs of the Australian War Memorial, the RAAF, Navy and Army Museums, Artlab Australia, and the Art Gallery of NSW.Read moreRead less
The twentieth century in paint. The art market is a major contributor to the Australian economy worth over $500M per annum. However many modern works created with new materials introduced in the 20th century in Australia and Southeast Asia exhibit problems with deterioration, and there is little research on the use and effects of these materials. Without answers to material based preservation questions collectors, curators and conservators cannot make informed decisions. This project, with partn ....The twentieth century in paint. The art market is a major contributor to the Australian economy worth over $500M per annum. However many modern works created with new materials introduced in the 20th century in Australia and Southeast Asia exhibit problems with deterioration, and there is little research on the use and effects of these materials. Without answers to material based preservation questions collectors, curators and conservators cannot make informed decisions. This project, with partners in Australia, Asia, US and UK will provide fundamental information to assist in formulating management strategies, inform curatorship and develop innovative approaches to conservation and the manufacture of art materials.Read moreRead less
