'Mini lens' grown in lab could help tackle cataracts

Scientists have found a way to grow a realistic human lens, potentially providing a new path for the treatment of cataracts, one of the leading causes of blindness worldwide. Researchers from Anglia Ruskin University (ARU), working with colleagues at the University of Osaka in Japan and Cardiff University, have created tiny "mini lenses" in the lab using human stem cells for the very first time.
