The popular dietary supplement ubiquinone, also known as Coenzyme Q10, is widely believed to function as an antioxidant, protecting cells against damage from free radicals.

To address these questions, Dr. Fabian Leendertz of the Robert Koch Institute in Berlin assembled a large international interdisciplinary team consisting of virologists, veterinarians, ecologists, epidemiologists and an anthropologist. One member was Jan Gogarten, a doctoral student in Biology and Vanier graduate scholar at McGill.
We spoke with Gogarten about the resulting study, published this week in the journal EMBO Molecular Medicine, and his role in it.
Learning from others and innovation have undoubtedly helped advance civilization. But these behaviours can carry costs as well as benefits. And a new study by an international team of evolutionary biologists sheds light on how one particular cost – increased exposure to parasites – may affect cultural evolution in non-human primates.
