Research turns popular oxidant belief upside down

Mitochondria are an important organelle in the cells on organisms, producing energy. However, a byproduct of this is the formation of reactive oxygen species, a type of free radical. New research shows however that free radicals may in fact improve survival, rather than cause conditions like skin ageing, meaning these may be much more beneficial than previously thought.
