DNA from a medieval skeleton in Portugal reveals XXY chromosomes

This article was originally published by the Australian Broadcasting Cooperation (ABC). We have reposted it here in its entirety to allow access for non-Australians and also to preserve information specific to the community. When Portuguese archaeologists unearthed the skeleton of a remarkably tall man who lived more than 1,000 years ago, they assumed he was …

New DNA ‘clock’ could help measure development in young children

Scientists have developed a molecular "clock" that could reshape how paediatricians measure and monitor childhood growth and potentially allow for an earlier diagnosis of life-altering development disorders. The research, published this week in PNAS, (Full Study) describes how the addition of chemical tags to DNA over time can potentially be used to screen for developmental differences …

The Genetic Origins of Sex Differences in Disease

It took almost 15 years for scientists to sequence and publish a complete accounting of the human genetic code — the 3 billion base pairs along the double strands of DNA that serve as a blueprint for the body’s functions and pass traits from parents to offspring. Now, approximately 15 years after the human genome …
