Stem cells

I'm not pretending to write about medicine or science here. I haven't even read the full news stories about it.

But quite a while back, there was news that some quacks somewhere in the world were claiming to cure disease simply by injecting people with stem cells.

It was stupid. Even if stem cells could be used to cure whatever illness or disability, it wouldn't be because you inject them into a person.

But...well...maybe the medical frauds were right.

Researchers injected stem cells into the eyes of a couple of blind test subjects. They didn't expect it to have any effect on their vision. The entire purpose of the experiment was simply to see if you could inject stem cells into someone's eyes. They could. And the people actually had some slight improvement in their vision, possibly as a result.
