The genes in our cells’ mitochondria are passed on in a different way than the vast majority of our DNA. New studies shed light on how the unique process isn’t derailed by mutations.
New evidence points to a possible burial site for South Australia’s Beaumont children, missing for 52 years. Specialist techniques will be applied to extract and sequence DNA if remains are found.
Genetic data is used to perform statistical analyses of disease associations.

One big challenge for gene therapies is delivering DNA or RNA safely to cells inside patients’ bodies. New nanoparticles could be an improvement over the current standard – repurposed viruses.

Lynn Margulis (1938-2011) was a courageous scholar whose remarkable work on the role of symbiosis in evolution stands as a magisterial contribution of science.
African Americans are being misdiagnosed with the heart condition (hypertrophic cardiomyopathy) that caused the sudden death of basketball player Hank Gathers (pictured left with teammate Bo Kimble) in 1990. Lack of ethnic diversity in genomic databases is a big part of the reason for these misdiagnoses.

Genome sequencing is transforming the way we diagnose disease. But lack of diversity in genomic data means only some Canadians will benefit from this revolutionary technology.
