Possible Sunscreen Tablet From Coral

Australia has the highest skin cancer rate in the world. This is because the population of this country is composed mainly of fair-skinned northern Europeans and Australia is very hot in summer. Despite advertising campaigns citing the dangers of sun bathing men still go around with no shirts and women bake in their back gardens or at the beach. If only people could take a pill to stop skin cancer.

Tests on a coral indicate that a tablet to prevent eye and skin damage from exposure to the sun may be within reach. The coral contains natural UV blockers. Though the coral is on the Australian Great Barrier reef, research is being done by the British government. Paul Long of King's College London is taking samples from Acropora microphthalma coral on night dives. Walter Dunlap of the Australian Institute for Marine Science noticed the attribute in 1986.

While the coral contains the UV protector, a base chemical is created by algae living nearby. The coral absorbs this chemical converting it into a natural sunscreen. Both the algae and coral benefit from the UV blocker as well as fish that feed on the coral. If fish are protected by eating the coral, humans could also benefit from consuming the coral or more practically by imbibing the UV blocking chemical. It is hoped that it will be possible to develop a synthetic version as the coral is endangered.

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 stol...

Beatboxing - Percussion Sounds of the Mouth

There must be a dearth of things to study. Scientists are now researching the odd sounds that people make. It may seem weird but its true. Those who can make odd sounds are called beatboxers. Scientists are interested in percussion sounds. These are expressed in Celtic, Chinese, North American and Indian cultures. Hip-hop is an area of great interest. A young "practitioner" had MRI scans done on his mouth while he created percussion sounds. The conclusion reached is that a lot of brainpower is involved in imitating percussion. It "is a small part of the larger puzzle," experts say. In my view it takes little mental concentration. Just put your tongue behind you top teeth a "tap" away. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml http://www.technorati.com/blogs/ . . . . . . . . . . . . . . . . . . . .
