A new study suggests that never-seen-before stem cells in the human retina can restore vision in mice with a common eye disorder. But more work is needed to translate the treatment to people. When you ...

Model of PEDF protein alongside the 17-mer and H105A peptides. Amino acid 105, which is changed from histidine in PEDF and the 17-mer peptide to alanine in the H105A peptide, is shown in green.

This snail could one day save eyes. The golden apple snail has camera-type eyes that are fundamentally similar to the human eye. Unlike humans, the snail can regenerate a missing or damaged eye. UC ...
