There is Soil on Mars

NASA scientists are now saying that "soil" on Mars could support vegetable life. Without an atmosphere, though, it seems no life is possible. Scientists are specific enough to say that asparagus and turnips will grow in Mars' soil but strawberries will not. Are they joking? Or are they for real?

The Phoenix Mars Lander found soil that is very much like that in many Earth backyards. Scientists are shocked that they have found soil. It is alkaline - thus, the claim that it is not good for strawberries. Apparently, the soil is rich in trace minerals.

My, how scientists can be wrong. It was thought that Mars "soil" would be salty - with no atmosphere and the sun would bleach it. But they were wrong. At least we know that there is soil and water in the form of ice just beneath the surface. There is evidence that in the past water flowed on the surface because erosion is evident. Rivers, lakes and oceans existed there once. Water reservoirs such as these indicate that the planet did once have an atmosphere.

If life did survive for a time on Mars future exploration will surely find it.

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