Water Chemistry in Caves is Changed by a Bushfire

The chemistry is altered in the cave water below a bushfire.
Raging fires on the surface of the planet affect caves that intertwine below. Research into climate history is now complicated by this finding. Australian and UK scientists analysed water dripping in cave after a fire and found that the chemistry of moisture changed.
Water on stalactites
There could be a new horizon, however. Stalagmites and stalactites store information about fires. The caves tested have clear data stretching back 200,000 years. Oxygen-16 is lighter than oxygen-18 and it evapourates quicker, so dripwater with more oxygen-18 would indicate fires or hot spells above.

Pauline Treble of the University of New South Wales found that sites in a cave only 23 meters apart had different water chemical readings. This was caused by a recent bushfire in 2005 localized to one of the cave sections.

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

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