Note that we are told, “they likely steal energy from their host using some type of proteins.” It makes sense that many devolved creatures are parasites. They can afford to throw away equipment if they are using the host’s toolbox anyway. Read More ›

Researcher shocked: Human mitochondrial DNA can be inherited from dads

Seventeen individuals from three unrelated multi-generation families have shown the trait (a high level of mtDNA heteroplasmy, ranging from 24 to 76 percent): A new study led by geneticist Taosheng Huang from the Cincinnati Children’s Hospital Medical Centre shows human mitochondrial DNA can be paternally inherited, in a landmark case that started with the treatment of a sick four-year-old boy. The child, who was showing signs of fatigue, muscle pain, and other symptoms, was evaluated by doctors, and tested to see if he had a mitochondrial disorder. When Huang ran the tests – and then ran them again to be sure – he couldn’t make sense of the results that came back. “That’s impossible,” he told NOVA Next. The reason Read More ›
