A new pair of genes

A disease which robs children of the ability to walk and talk has been cured by pioneering gene therapy to correct errors in their DNA, say doctors. The study, in the journal Science, showed the three patients were now going to school. A second study published at the same time has shown a similar therapy reversing a severe genetic disease affecting the immune system. Gene therapy researchers said it was a "really exciting" development. Both diseases are caused by errors in the patient's genetic code - the manual for building and running their bodies. Gene therapy has come so far in recent times - clinical trials have succeeded in treating Parkinson's and giving mice back their sense of smell. So to all you naysayers stuck in the past, I have this to say to you: you can't stop progress. And you can't stop Gangnam Style either - it's almost at 1.75 billion views.
