I don’t disagree with that quote by educator and humanitarian Helen Keller, a woman who overcame her inability to see, hear and speak, and graduated from college in 1904.

However, I’m extremely squeamish when it comes to eyes. Perhaps it started in grade 8 science class when we had to dissect a cow’s eye…? Remember Stanley Kubrick’s A Clockwork Orange? GROSS!

When I came across this video about using human embryonic stem cells (hESC) to treat vision loss, I was sure I’d have to avert my own baby blues. Much to my surprise and delight, this is a very clear, simple and nicely illustrated description of how the science works and there are no close-ups of eyeballs.

You can read the study in the Lancet here.

Our regular feature, Right Turn, showcases the “lighter” side of stem cells and regenerative medicine. Every Friday, we will bring you cartoons, photos, videos and other content that may be just as thought provoking as the written submissions that you are used to finding here, but they definitely won’t be blogs.

As always, we welcome your feedback and we also welcome suitable submissions. Be creative! Use the right (!) side of your brain. Make us laugh! Let’s see if we can make this new direction a positive one for all of us. Send your submission to info(at)
