What technology or advancement did you read about? 

How will this improve the field that it is going to be used in? 

What makes this advancement better than what was being used previously?

Do you think this new advancement is safe? 

Is it already being used on patients or is it still in the development stage? 

I read about prostetic limbs. I saw a device that moves them with your mind. You could also feel with it. Before you couldn't feel. You could not move it with your mind either. I think this is very saffe.It is sasfer than before. Itis already being used but they are beta testing. Ut's amazing.
