I love it when scientists do amazing things, such as curing blindness in mice. Researchers at University College London transplanted light-sensitive eye cells, called rod photoreceptors, into partially blind mice. To test whether the mice with the transplants could see better, they placed them in a dark, watery maze. The mice could see enough to successfully swim out of the maze.

These results are very encouraging for treating blindness, which affects millions worldwide. The next step is to use cell transplants in human patients.
