Free radical pollution in the air could be a cause of asthma. Chemists have discovered that the atmospheric nitrate radical irreversibly damages amino acids, which are the building blocks for proteins ...
When human cells are attacked by free radicals, the antioxidant vitamins and minerals in the food we've eaten come to our defense. However, when brown kelp (Laminaria), a kind of seaweed, is stressed, ...
