Like South Africa, Australia is known as a region of frequent shark attacks. A lot of research has been done over the years in an attempt to reduce such attacks. Humans are not normal food for sharks. It is when humans behave in a similar way to injured fish that attacks occur. Electronic pulses and sounds have been tried with limited success. Colored diving suits have also proven to be ineffective, until now. It has been discovered that blue lines on wetsuits disrupts the vision of sharks because they are color-blind. White stripes also work as a deterrent but in a different way. Poisonous fish have white on their bodies. It tells potential predators that eating them will have dire consequences. The cryptic wetsuit that "blinds" sharks is aimed at divers, while the white stripped warning suite is for those close to the beach. Diving equipment and surfing gear is also being colored to match the wetsuits. Though shark attacks cannot be stopped entirel

Human beings may be having problems with variable weather in Australia, but animals are coping well. Zebra finches, pelicans and woodswallows seem to know when the weather changes. If the Spring comes early they nest early. If it is too dry to breed they hold off until times are better. They change their breeding point by months either way. When glaciation was at its peak the woodswallow population actually boomed. In boom times there is a larger pool of gene carriers ideal for genetic selection when times become harder. More of the birds die off. Yet, the survivors have traits that suite the changed environment. Australia has the harshest of climates with long periods of drought. Consequently, birds such as pelicans live a longtime on a meagre diet so they can wait for good times to breed. Zebra finches seem to do well even when times are very hard. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml

The Queensland state government is making drastic changes to the way young people who commit crimes are treated. Young offenders are to be named and shamed. Those punished by being sent to institutions will be transferred to adult prisons when they reach the age of eighteen. Many of the "young criminals" are victims of crime themselves. Difficult home life has pushed them into crime. Naming them would make their lives intolerable. The government decision has been made on just one survey. It seems the decision was made before the survey began. Young people are not mature adults. They are growing and learning. Judging them at such a stage in their lives is marking them as bad citizens for life. Other changes include making fixed penalties for some crimes committed by adults. Judges will not have the discretion to modify the sentences according to prevailing circumstances. A change that just about everyone agrees on is courts knowing the case histories of adult defen

Microsoft is going to offer a way for consumers to get around national firewalls. It is aimed at domestic US consumers to access corporate resources but it will make for a revolution in bypassing national restrictions, particularly for music and television programming. Of course you will need a Windows mobile phone to access the feature. This is a trump card that Microsoft has played. However, like with cloud services when one enterprise gives something extra all competitors provide it as well. While it is essentially for business use, VPN access will ultimately be used to access local content in countries that restrict it to their citizens. Just how program providers will react to this is not known. This announcement has been a surprise. However, many users pay a few dollars a month for VPNs already. It makes for easy use of programming supposedly blocked for overseas people. If business gets "free" use of VPNs, the ordinary consumer will want it too. Soon rivals

For many years it has been said that Australia lacks maths and science graduates. Maths teachers are in short supply we are told. Professor Ian Chubb, a chief scientist, certainly pushes this case. Unfortunately, data does not support this premise. Like qualified information technology people, maths and science graduates find the job market difficult. It seems there is real demand only in geological science. A little more than half of graduates say their qualifications are relevant to their work. They hold down jobs only in distantly related fields. One would think that with science and technology moving forward at a rapid pace such qualified people would be sorely needed. Employment in agricultural science is falling because young people are leaving rural towns and refuse to learn about farming. It is seen as glorified laboring. Getting a post-graduate qualification does not help to find work. Employers see higher degrees as narrowing educational scope. Government is cont
