 | The 5,300 year old human mummy -- dubbed Öetzi or "the Tyrolean Iceman" -- is highly unlikely to have modern day relatives, according to new research published today. ...> Full Article |
A new study uses a sophisticated genetic strategy to reveal new roads past an apparent dead end in the historical record of a distinctive civilization that dominated the Mediterranean Sea during the first millennium BC. The research from National Geographic and IBM's Genographic Project, published by Cell Press in the Nov. 14 issue of the American Journal of Human Genetics, describes a methodology that may prove to be useful for discovering previously undetected signals left by migrations for any historically documented expansion.

Researchers have traced the evolutionary origin of two genes that serve as primary cellular sensors of infection with RNA viruses, such as influenza, polio virus, West Nile virus, and HIV, which may ultimately provide researchers with insight into a possible new pathway for the development of innate immunity.

 | Hawaiian Islands have given up another tantalizing peek into evolutionary history as a team of botanists using the latest molecular techniques has traced the origin of the islands' spectacular array of 125 species of lobeliads to a single colonization event some 13 million years ago. ...> Full Article |
The discovery of the earliest known cases of human tuberculosis in bones found submerged off the coast of Israel shows that the disease is 3000 years older than previously thought. Direct examination of this ancient DNA confirms the latest theory that bovine TB evolved later than human TB.
