Researchers identify unique cases in which people inherited mitochondrial DNA not just from their mother but also from their father.

Researchers used TALENs and zinc finger nucleases to correct disease-causing mutations.

A transgenic approach allows researchers to collect the organelles from specific cells in nematodes with unprecedented efficiency.

Adding a fusion gene to certain mitochondria in C. elegans enables researchers to collect and analyze them.

Mitochondria age differently depending upon whether they’re located in the liver, heart, or kidney, scientists find in flies and mice.

The team that oversaw the first use of mitochondrial replacement therapy that resulted in a live birth has published an account of the procedure.

Mitochondrial replacement therapy raises important societal and ethical concerns, but should be embraced for its utility in preventing disease.

Differences in the replicative advantages conferred by some mitochondrial DNA haplotypes have implications for mitochondrial replacement therapy, researchers report. 

Examining the tragedies of several families who each lost multiple children, two teams of researchers reveal a previously unappreciated role for a mitochondrial enzyme.
