Professor Graham Stewart AM, director of clinical immunology at Westmead Hospital has researched the genetic influences on disease, in particular on multiple sclerosis (MS). MS is the commonest chronic neurological disorder of young at all. It usually starts with a relapsing/remitting phase (with symptoms occur and then go into remission at for extended periods), usually with onset at about the age of 30. The disease can be relatively benign with periods of disability, it can present as a relapsing/remitting disease with gradual increase in disability, or in about 10-20% of patients it can present as being "primary progressive”, where disability progressively increases over time.
MS is caused by the body's immune system malfunctioning – macrophages devour the myelin sheath around nerve cells, exposing the nerve axon and thereby disrupting the flow of information along the nerve cell. The body is able to repair the damage by re-myelinating the nerve cells after this initial attack however if the myelin is attacked the second time in the same place, the body is unable to repair the sheath and relapse occurs. Hence the symptoms of the disease progress. (Read more...)
In 2008, the world suffered "the equivalent of cardiac Arrest”, according to the Financial Times. It became virtually impossible for any institution to finance itself, (that is, borrow in the markets) longer than overnight. With the collapse of Lehman Bros, interbank credit markets froze and counterparty risk was considered to be too great for prospective lenders to take on the transactions. The London interbank overnight lending rate, typically in the range of 0.2% to 0.8% spiked to over 3%. This situation raises two questions: what caused this global financial crisis (GFC)? and how can we attempt to avoid similar crises in the future? The origins of the crisis go back more than 30 years.
Starting in 1977, there were substantial changes made to US investment legislation. Early in this period, the aim was to make finance more readily available to low-income borrowers, to progressively eliminate using the controls on mortgage rates and to remove discrimination in the US housing market.

At the 1220th ordinary general meeting of the Society, Laureate Professor Graeme Jameson described the development of the Jameson cell, one of the most important technological contributions to the Australian economy in the last 50 years.
The Jameson cell is a flotation cell used in minerals processing. First two stages of extracting minerals are the mine itself from which the ore is recovered and the concentrator, where the valuable mineral is extracted from the rest. Typically the valuable components are no more than 2% of ore recovered, so there is a massive challenge in isolating this from the ore for further processing. An important technology developed to achieve this concentration step was the flotation cell, a process first developed early in the 20th century. (Read more...)
Hugh Durrant-Whyte is an internationally-recognised expert on the analysis of "big data” – the mass of information that is being generated around current information and communication technologies. Much of this is "metadata” – data that is captured as part of some activity (for example, when a digital photograph is taken also recording camera settings, capture date etc or the data kept by telecommunication companies every time a mobile phone call is made).
2.5×1018 bytes of data are generated every day – there is immense value in mining this data but this requires sophisticated analytical techniques. "Data analytics” is the term coined for technologies to analyse this data in areas as varied as the finance industry, the health industry, planning infrastructure, failure analysis in mechanical and electronic equipment and environmental analysis, to name but a few examples.

At the annual Four Societies Lecture, Professor Mary O'Kane considered the major questions that face NSW in the future of energy production and utilisation. Asking the right questions is key – it reduces the time taken to identify the best solutions.
Australia is the ninth largest energy producer in the world and one of only four net energy exporters. We have 38% of the world's uranium, 9% of the world's coal and 2% of the world's gas. In terms of consumption, agriculture takes 3%, mining 13.5%, manufacturing and construction 25%, transportation 38% and residential about 11%. The 2014 Commonwealth Energy White Paper is seeking to address a number of questions regarding Australia's energy future. (Read more...)
At the first joint meeting of the Society and the Australian Academy of Forensics Sciences, Professor Robyn Sloggitt explain the approach taken by forensics scientists in investigating prosecuting cultural heritage offences. The difficulty that faces authorities is determining whether or not cultural records are true and verifiable. Forensic examination used in these situations follows the Locard principle (named after Edmond Locard the pioneering French forensics scientist) that "every contact leaves a trace”.
In order to determine the provenance of works of art, the forensics it seeks to establish how the object was made, what it is made of, when it was made and where it was made. (Read more...)
