The mitochondrial DNA of the first Near Eastern farmers has been sequenced for the first time. In the research, published in the journal PLOS Genetics, experts analysed samples from three sites located in the birthplace of Neolithic agricultural practices: the Middle Euphrates basin and the oasis of Damascus, located in today's Syria and date at about 8,000 BC.

The paper is signed by Daniel Turbón and Alejandro Pérez Pérez, from the Department of Animal Biology of the University of Barcelona (UB); Eva Fernández, from Liverpool John Moores University; Cristina Gamba, Eduardo Arroyo Pardo and Pedro Cuesta, from Complutense University of Madrid; Eva Prats, from the Spanish National Research Council, and Josep Anfruns and Miquel Molist, from the Universitat Autònoma de Barcelona (UAB). The study is focused on the analysis of mitochondrial DNA --a type of non-Mendelian maternally inherited DNA-- from the first Neolithic farmers, by means of samples obtained by the UAB research group which were first processed by the UB research group.

New genomic research led by UC San Francisco (UCSF) scientists reveals that two common gene variants that lead to longer telomeres, the caps on chromosome ends thought by many scientists to confer health by protecting cells from aging, also significantly increase the risk of developing the deadly brain cancers known as gliomas.
