Annual Meeting of the Four Societies 2017

Four Societies 2017   “South Australia: a nuclear State in a global
  solution”

  Rear Admiral, The Honourable Kevin Scarce AC
  CSC RAN (ret'd.)

Thursday 23 February 2017
International Convention Centre, Darling Harbour

This talk focused on the challenge to Australia in moving to a reliable, low-carbon and lowest-possible-cost electricity system. Nuclear power is a proven, low-carbon energy source and may have a role to play in Australia. South Australia has abundant uranium resources and furthermore, with the combination of geological, political and technical factors, the State may provide a global solution for the permanent disposal of used fuel. The benefits of being a nuclear State could be game-changing.

Rear Admiral, the Honourable Kevin Scarce is the 16th Chancellor of the University of Adelaide and was the 34th Governor of South Australia from 2007 to 2014. He served in the Royal Australian Navy from 1968, retiring in 2004. His appointments included service on HMAS Sydney during the Vietnam War. He specialised in military logistics and procurement, rising to the rank of Rear Admiral and Head of Maritime Systems at the Defence Materiel Organisation. After retirement, as Head of the South Australian Defence Unit, he led a government team that contributed to ASC winning the contract to build air warfare destroyers for the Australian Defence Force. He was awarded the Conspicuous Service Cross in 1994, the Knight of Grace in the Venerable Order of Saint John in 2007 and a Companion of the Order of Australia in 2008. He completed a Bachelor of Financial Administrationfrom New England, Masters of Management Economics at the University of New South Wales (Australian Defence Force Academy campus), and a Masters Degree in National Security Strategy at the US War College (National Defense University) in Washington, DC. He was awarded an Honorary Doctorate from Flinders University in 2009 for distinguished service to the public of South Australia and an Honorary Doctor of Letters (honoris causa) from the University of New England in 2014. He was appointed on 29 March 2015 as the Commissioner of the South Australia Nuclear Fuel Cycle Royal Commission.

“Effects of maternal cigarette smoke exposure on brain health in offspring”

We do not understand well how maternal smoking and secondhand smoke exposure during pregnancy can cause lifelong adverse effects in the offspring, especially in their neurological function. Maternal cigarette smoke exposure is a risk factor for the shutdown of blood and oxygen supply to the brain. This can lead to several functional defects, including problems with movement, sensation, strength, and thinking, increasing the financial burden of both the family and government. My work aims to understand how maternal cigarette smoke exposure affects brain health, to allow the discovery of therapeutic targets for potential interventions. He described the various experiments he conducted with mice to identify the effects of smoke exposure on behaviour and brain function.

“New ways of modelling the ancient past to understand evolution”

Molecular dating, powered by increasing floods of genetic data, is allowing biologists to look ever more closely at the central mystery of evolution – the origin of species. At the same time, the digital revolution has led to the application of biological methods to surprising new types of data – such as the imprints of human history left in the relationships among world languages. To do this, biologists and linguists construct models that interpret genetic and lexical data in the light of our assumptions about the evolutionary process. In this talk, he described the available models and his findings regarding their powers and pitfalls for analyses of the ancient past.

“Anarchy in the honey bee colony: the genetic basis of worker sterility”

Currently little is known about the mechanisms that underlie worker sterility in the social insects.Studies into a mutant ‘anarchistic’ strain of honey bee identified a promising candidate gene for regulating worker fertility. My results suggest that this Anarchy gene is involved in the regulation of the worker’s ovary via the mechanism of programmed cell death. My findings indicate that a pheromone from the queen honey bee affects the Anarchy gene and triggers the reproductive inhibition of the workers. This is a breakthrough in understanding the mechanisms of worker sterility in the social insects. In this talk she described some of the fascinating characteristics of bee colony behaviour and the experiments she conducted to show how the worker bees reproductive organs were affected by the Queen's pheromone.
