All claim matrilineal descent from a Native American woman, usually named as Cherokee. The main criterion for inclusion in the study is that test subjects must have obtained results not placing them in the standard Native American haplogroups A, B, C or D. Hence the use of the word “anomalous” in the title of a paper prepared by chief investigator Donald N. Yates, “Anomalous Mitochondrial DNA Lineages in the Cherokee.”

Does physical activity influence the health of future offspring?

Physical and mental exercise is not only beneficial for your own brain, but can also affect the learning ability of future offspring — at least in mice. This particular form of inheritance is mediated by certain RNA molecules that influence gene activity. These molecules accumulate in both the brain and germ cells following physical and mental activity. Prof. André Fischer and colleagues from the German Center for Neurodegenerative Diseases (DZNE) in Goettingen and Munich and the University Medical Center Goettingen (UMG) report these findings in the journal Cell Reports.

Music lessons improve children’s cognitive skills and academic performance

Structured music lessons significantly enhance children’s cognitive abilities — including language-based reasoning, short-term memory, planning and inhibition — which lead to improved academic performance. Published in Frontiers in Neuroscience, the research is the first large-scale, longitudinal study to be adapted into the regular school curriculum. Visual arts lessons were also found to significantly improve children’s visual and spatial memory. Continue reading “Music lessons improve children’s cognitive skills and academic performance” →
