Doris Taylor and colleagues used a process called decellularization to wash away existing cells from the hearts of dead rats while leaving the basic collagen structure intact.
They injected this gelatin-like scaffold with heart cells from newborn rats, fed them a nutrient-rich solution and left them in the lab to grow.
Four days later, the hearts started to contract.

Wow. This is amazing. Although it looks more like chewing gum than a heart.

You've been tagged.
The name of this Meme is Secrets and Lies. All you have to do is post an entry on you blog containing a secret and a lie. Words, pictures, video, any topic, it’s up to you. You have been chosen for your creativity, wit, charm and personality. Your secret, your dogs’ secret, any lie will do. Remember a lie can be a secret and a secret can also be a lie. Maybe that’s just politics? Anyway, strangely enough the title of the post should contain the words ‘secrets’ and ‘lies’.
Then find five friends and/or strangers to tag. They may or may not take up the challenge, that’s not your problem.
Have fun!
