Rewinding the biological clock helps blind mice to see

Cells in the eye appear to be ‘younger’ after treatment

Researchers claim to have reversed ageing in mice. It has long been believed that if we understand the causes of ageing, it may be possible to reverse it. New work on mice shows that it is possible to cure blindness caused by old age or injury. Researchers think that this effect may depend on rewinding the ‘biological clock’ which marks the age of cells, suggesting that the cells in the eye have been made functionally younger.
