Stem cell research carried out by biomedical scientists has enabled a man who was left partially sighted after intervening in a fight to recover his vision.
In 1994, Russell Turnbull lost most of the sight of his right eye after being sprayed in the face with ammonia while trying to break up an altercation on a bus, the Times reports.
The 38-year-old was left with pain, extreme sensitivity to light and cloudy vision.
