Researchers at the University of Leeds have devised a more accurate method of dating ancient human migration "“ even when no corroborating archaeological evidence exists.Estimating the chronology of population migrations throughout mankind's early history has always been problematic. The most widely used genetic method works back to find the last common ancestor of any particular set of lineages using samples of mitochondrial DNA (mtDNA), but this method has recently been shown to be...

Sensory ataxic neuropathy (SAN) is a recently identified neurological disorder in Golden Retriever dogs with onset during puppyhood. Affected dogs move in an uncoordinated manner and have sensory deficits. Researchers from the Swedish University of Agricultural Sciences, Uppsala University and the Karolinska Institutet have now revealed that SAN is caused by a mutation in mitochondrial DNA. The study is published May 29 in the open-access journal PLoS Genetics.The researchers were able to...

The Neanderthals inhabited a vast geographical area extending from Europe to western Asia and the Middle East 30,000 to 100,000 years ago. Now, a group of researchers are questioning whether or not the Neanderthals constituted a homogenous group or separate sub-groups (between which slight differences could be observed). A new study published April 15 in the online, open-access, peer-reviewed journal PLoS ONE may provide some answers. Paleoanthropological studies based on morphological...

A fundamental process in the transmission of genes from mother to child has been identified by researchers at the Montreal Neurological Institute, McGill University. The new study published in the December issue of the journal Nature Genetics identifies a mechanism that plays a key role in how mutations are transmitted from one generation to the next, providing unprecedented insight into metabolic diseases.DNA that is only passed on from mothers to their children is stored in mitochondria, a...

By Grand Forks Herald, N.D. Aug. 6--By Tom Johnson Why do we eat? This seems like a simple question. But when I asked several people, I received a variety of answers: "To nourish my body" or "because I'm hungry" and some far-out answers loosely related to the cosmos and our place in the universe. While the answer to the question is simple -- we eat to get energy -- the process of converting food into energy is complicated. The important task of converting food calories into usable...

A new study has revealed that nearly all of the Native Americans in the western hemisphere can be traced through DNA to six women whose descendants first immigrated from Asia 20,000 years ago.  Researchers said these women left a DNA signature that can be found in about 95 percent of today's Native Americans.  Ugo Perego from the Sorenson Molecular Genealogy Foundation in Salt Lake City and the University of Pavia in Italy is the study's co-author.  He told Associated Press...

In a potential breakthrough for the treatment of serious hereditary diseases, British Scientists from Newcastle University have created ten test-tube human embryos, each containing the DNA from one man and two women.  The scientists, led by Professor Doug Turnbull, believe the procedure could someday be used to prevent women with faults in their mitochondrial DNA from passing the disease on to their children. Mitochondrial DNA is passed down only through the female line.Mitochondria...
