CDN breakthrough: Creating patient-specific nerve cells from blood

This is a potentially momentous success, but look a bit beyond the science itself. Instead of rushing out to publish, the researchers first "couldn't believe that their method had worked" and that only after "repeating the procedure several times over several months" were they convinced that they had actually done everything correct.

That is exactly the way that science needs to be done. First of all doubt your result, and check every aspect that you can think of before going public. The bigger the result, the more important the internal check. After all, if you don't find the mistake, someone else will. 

So, kudos to these folks on their success, and kudos for checking your result multiple times before going public. 

Stem cell researchers from McMaster University in Hamilton, Ont. say they have learned how to convert cells from blood into both central nervous system neural cells — which are the neurons in the brain and spinal cord — as well as cells from the peripheral nervous system, which are the nerves in the rest of the body that are responsible for sensing pain, heat and itches.
