Asian Tiger Mosquitoes Moving To the Australian Mainland

With climate change insects move geographically. New regions open up to be populated. Warming of the Australian mainland has taken place. The Asian tiger mosquito has been found on Thursday and Horn islands in the Torres strait close to Australia itself.

Dengue and chicungunya are the greatest dangers. These diseases can be fatal. There is no way the mosquitoes can be stopped. They will move into Australia proper. Spraying insecticides will only slow them down. They won't fly to Australia. They will be brought here on small boats moving all over the Torres Strait.

The threat is serious. Once established in Australia Asian tiger mosquitoes will be spread by humans as far south as Tasmania. They prefer a cooler climate than the main dengue host, Aedes aegypti. Tigers will carry dengue, however.

The outside-life of Australians is under threat. Having a barbecue will be a dangerous pastime. Recently it has been established that mosquitoes are not native to Papua New Guinea. They came from Indonesia, so migration is normal for the insect.

Consuming More Tea and Coffee Prevents Diabetes - Doubtful

Claims about consuming certain things to improve health are way off beam. Every now and then supposed new research shows that if you eat this or don't eat that your health will improve. Years late we discover that the "experts' were totally wrong and your health was actually damaged. This happened with margarine, milk, eggs and so on. What is the latest? Well, apparently drinking up to three cups of coffee or tea each day reduces the risk of getting diabetes. Look around. Do you see people who drink these beverages regularly with diabetes? You sure do. There are thousands of them. The University of Sydney says “If such beneficial effects were observed in interventional trials to be real, the implications for the millions of individuals who have diabetes mellitus, or who are at future risk of developing it, would be substantial.” Their trials must be wrong. Surely millions of regular drinkers who have diabetes are thinking, "Why me? Why have I got the disease&qu

Anthropology Has New Theory on Australian Aboriginals

New theory on Australian Aboriginals - Anthropology. Australian Aboriginals split from Eurasians and moved south into the dry continent. Twenty thousand years later the world warmed up and Australia was cut off from its northern neighbors. This is the latest theory. But when Europeans initially came to Queensland there were two types of native people. Each was a distinct genetic pool. One was like Papua New Guineans. The other was very slight and shorter. It is the latter that predominates today. Papua New Guineans Australian Aboriginals Some scientists still hold that there was only one move out of Africa. This is an unsustainable supposition. The doors for movement were always open. Australian Aboriginals were quite unique. It seems that they were the first to leave Africa. There is also the question of Tasmanian Aboriginals who were wiped out by arriving Europeans. There is no evidence of them now. They could not light fires. The flames had to be stolen f
