Believe it - X-ray with Cellotape

It is possible to see through sticky tape. But such tape can also help you see through things! The action of peeling tape off a roll actually produces x-rays.If the tape is quickly stuck to a finger bones become visible. This was not discovered by someone actually seeing that this happens, even though it has been obvious for anyone to see for years. People are funny that way - put something under their nose and they won't see it. Actually, it was discovered by Russian scientists who noticed that peeling tape from a roll created bursts of x-rays seen on a meter.

The Russians increased x-ray emissions by peeling the tape off in a vacuum. The scientists were shocked to make the discovery. They could not believe that no one had actually observed this occurring by trial and error.

It works by triboluminescence. When tape is pulled from the roll the sticky acrylic becomes positively charged, while the roll remains negatively charged. For a billionth of a second the negative ions on the tape "bang" into the roll, i.e., electricity flows. This creates x-rays.

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/ . . . . . . . . . . . . . . . . . . . .
