Genetics Identifies Cause of Sudden Death in Young People

Sudden death in young people has a genetic cause - Long QT syndrome.
There is a predilection for some young adults to suddenly die. In a way it is similar to cot death: until now the cause was unknown. The "disease" has been identified and is called Long QT syndrome. A third of sudden "unexplained" deaths in people up to their mid thirties die of heart rhythm complications due to the inherited illness. The heart problem is not always evident in autopsies.
Long QT syndrome
Parents can also die of the condition in later life. The faulty gene runs in families and is generally passed on to some offspring. A gene testing study of children having symptoms of heart disease is showing that many carry the gene. 

Ongoing monitoring of youngsters is saving lives.  However, there is no official program that tests all children.  Some, of course are not diagnosed early and it is these who are at risk of sudden death.  It is heart breaking for a family to lose a child in this way,

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