Two New Species Carrying Irukandji Found in Australia

It never fails to amaze me how new things are discovered on our doorstep when the majority of people think everything is known about nature.  This is particularly true in Australia where a low number of people live on a vast continent.  Some places have not even been visited by humans for thousands of years.

Dr Lisa-Ann Gershwin has identified two species of jellyfish that can carry Irukandji syndrome.  The new species are Keesingia gigas and Malo bella.  Doctor Gershwin works for CSIRO.  There are now 16 species that can cause Irukandji.

Keesingia can grow to 50 cm in bell height.  This is by far the largest jellyfish.  Juvenile leatherjacket fish safely live in its subumbrellar cavity as with the more common medusas.

The two newly documented species have been generally known for some time.  However, they have not been found in Australian waters before.  They could have been present for a long time or maybe they are new, moving here due to climate change and the warming ocean.

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