Growing Organs?!?!?/ Justin Bieber Hair

I just read an article that was talking about growing organs! http://ngm.nationalgeographic.com/2011/03/big-idea/organ-regeneration-text

I think this is really cool and interesting that scientist are growing organs.  If I were in a place where I needed a new organ I think I would consider this option.  I think this will be very helpful for the 100,000 people waiting for an organ transplant.  I hope that if they figure out what to do and how to transplant a grown organ, that 18 people won't die everyday due to not getting a transplant.  Scientists can grow a bladder in 6 to 8 weeks, and are starting to grow more major organs.  In order to make sure the organs are working like they should, they are being tested on animals.  I do not like that they are testing on animals but understand they want to test on them before humans but I still don't think it is right.  I think they could find other ways to test new organs and other things on a human-like machine that some one would create.


Justin Bieber's hair sold for how much?!?

I am glad that the $40,668 went to a animal rescue group and will really help out some great animals that might not have a chance if this money wasn't donated.  But really I think that is a lot of money for Justin's hair.  How much would people pay for a nail clipping if they paid that much for Justin's hair.  Boy charities might be getting a lot of money from this kid.
