Stem cells

This is the XXI century, as I try to keep in mind, and the things that were supposed to happen in the future are in fact starting to happen :)

For example, there are 2 new incredible results from the stem cell research:

1. we soon will not need to use embrios to generate stem cells, at all: your normal cells will be reactivated, so they can behave as if they where in an embrio (yours actually), and become whatever kind of tissue you need. Need a new kidney? Just provide a few cells :)

2. and recently researchers have been able to fix the spines of laboratory rats, and make them walk again. Cool, eh?
   Detauls here.
   

My father actually loosed a kidney recently, he is fine, but I cannot avoid being thrilled by news like these!

Generation of the '70s... welcome to our future.
