SOCIOLOGY Class in sociology is based in income - low, middle and high income earners, plus wealth. This is in conflict with assumed class by the ordinary person who believes that class is based on status. In England, for example, one's position in society can be inherited. An English earl will remain high class even though he has little income and lets the paying public into his home to pay for its upkeep. Anyway, let's get back to the issue, "at large", which is how income and wealth inequality has changed in Australia. Egalitarianism is an Aussie "thing". There is a strong belief that all Australians are equal, in daily interactions at least. An Australian can have a drink with the CEO of the business where he works. In England this is unthinkable. It simply will not happen because the boss will not allow the lowly employee into his/her circle. In the 1950s income in Australia was relatively level. It was far more equal than in other Weste

genetics The gene responsible for schizophrenia has been found. Contrary to the popular view the ailment doesn't only cause multiple personality issues. It has three variants: 1) Positive , causing delusions, dysfunctional thoughts, movement irregularities and hallucinations; Negative , unhappiness, not finishing activities, reduced speaking and low bodily expression; and Cognitive , poor decision making, low attention, memory problems. Ten in a thousand people suffer from schizophrenia.   It usually begins before the age of 30 years. In 2014 an international program was organized to isolate the causative gene. It has been identified in the major histocompatibility complex (MHC). The C4 gene goes wild in sufferers, binding to more foreign molecules. This reduces the synaptic connections in the brain. Hopefully, a new more specific medication can be produced from the research data. Currently, drugs are not effective because the target has been unclear.  lifelong tre

SOCIOLOGY Work is being done to make the earliest human habitation of the Great Swan Region in Western Australia clearer. This covers the glacial period before the post-glacial sea rise, 30,000 to 6,000 before the present. Aboriginals were making flake stone tools. Though for the most part natural forming cutting edges of quartz and chert were utilized Aboriginals evolved to adapt to hot conditions they survived the extremely cold conditions. Rottnest Island was inhabited during the fall in sea level but not thereafter. Aboriginals do have folk memories in the their culture about a past period when trees grew on intervening land now beneath the sea. The sea flooded in 6,500 years ago, quite recent. Pollen records of close onshore land that wetland and woodland. There were changes over the years as the climate changed. Aboriginals did not take to cave dwelling as they had to hunt for food. They lived in the open around fires. Bush food and fresh water were available t

science Interesting things abound about Australia. It is a unique continent being isolated from the other land masses for millions of years. Animals have evolved with unusual behaviors. The cute, tiny Antichenus gets so high on testosterone that the little fellow doesn't eat or drink. He mates until he dies. The ugliest fish live in the deep sea off Australia's coast. They have large eyes, a necessity where light is almost total nonexistent.  Land creatures have evolved where some beauty is required to facilitate mating.  living in the darkest depths means seeing your mate is not so important, but large eyes, huge jaws and venomous spines are. Tourists and locals know about the deadly creatures living here. Oddly, Funnelweb spiders are not dangerous to dogs, cats, mice, lizards or snakes. An unlucky human can die if bitten by this spider.  Muscles in our bodies fibrillate.  Unsynchronized contraction of heart muscles can kill us. Bundaberg is the home of the world

technology Despite the advances in artificial intelligence, useful robots are a long way off. Humans can do limitless things, whereas robots can only do one thing well. They cannot have the broad perspective. So don't hope to have a "Maisy who washes the dishes and cleans the house anytime soon. Businesses want to profit from new technology. However, adapting quickly to advances in artificial intelligence is difficult. The business that shows the way will be the winner. Those who follow will have to pick up the scraps. The leading business will have moved on to something else. The time is approaching when the first damaging, even fatal, decision is made by a computer. It could be a major disaster. Artificial intelligence is not sentient: it does not feel any harm it does. Machines can now learn both good and bad. To a computer everything is equal. Give a robot a conscience - that will be a great leap forward! ◆ Technology by Ty Buchanan   ◆ Adventure Austral

SOCIOLOGY Many in Australia are calling for a guaranteed minimum wage whether a person earns it or not. If a low paid job for say 30 hours a week is below this minimum then the state will top it up. This sounds fair at first instance, but there is the problem of government income to pay for this and the world economic environment that thrives on low wages. If every country in the world did it, the system would be viable. Unfortunately, humans are greed driven. We are nice to each other. This in only to a degree, however. Man is torn between egalitarianism and competition. The Star Trek world where only those who want to work abandon their sloth and actually go to work is far off in the future. When I was young the dole was quite high. It was meant for times between jobs to maintain family income. Indeed, in England those who paid more tax got a higher rate of unemployment. This was definitely not egalitarian. The Australian benefit has fallen way behind the cost o

GENETICS I've been everywhere man - I mean mouse! João   Gonçalves  Zarco, the Portuguese explorer, thought he had discovered a pristine island untouched by man. However, Madeira had been reached earlier by other people . Mouse move with man and their genetic fingerprint showed that Vikings had got there first. Mice began "travelling" with humans when people stated storing grain. There is nothing like a free feed to hitch a ride. As grain was moved aboard ship, mice got on too. When a ship reached its destination the mice alighted and started a new colony of their own. The mice who populated Madeira do not have DNA traces of Portuguese mice. They are related to north eastern European mice. Apparently, viking did not construct any lasting structure on the island. This is also the case in North America where very little evidence has been found of Viking exploration. Carbon dating of mice skeletons on Madeira show the earliest to be 1,000 years old. T
