I could sit here and watch this all night, so refreshing.
"Mad was the last kid I saw and he was asleep. He was 3 months old and they put him in my arms and he stayed asleep and they put him in the bath and he stayed asleep and I thought he was narcoleptic or something. Then he opened his eyes and just stared at me for the longest time and I just stared at him and I started crying and he smiled. And it wasn’t that he smiled that he liked me, it was just that I hadn’t held children in my life and I was always considered so dark and I always had so many things that made me feel like maybe I shouldn’t be somebody’s mom because certainly the world has an opinion of me and I’m not so sure about myself and am I gonna be the best mom? So the fact that this little kid seemed at ease gave me the courage to feel like I could make him happy. And so we became a family right then." — Angelina Jolie
Some do drugs, others go out for a run, but at the end we’re all just searching for that tiny space, perhaps a hole, that gives us shelter from the terrible reality of the world.

I’ve seen this photograph very frequently on tumblr and Facebook, always with the simple caption, “Ghost Heart”. What exactly is a ghost heart?
More than 3,200 people are on the waiting list for a heart transplant in the United States. Some won’t survive the wait. Last year, 340 died before a new heart was found.
The solution: Take a pig heart, soak it in an ingredient commonly found in shampoo and wash away the cells until you’re left with a protein scaffold that is to a heart what two-by-four framing is to a house.
Then inject that ghost heart, as it’s called, with hundreds of millions of blood or bone-marrow stem cells from a person who needs a heart transplant, place it in a bioreactor - a box with artificial lungs and tubes that pump oxygen and blood into it - and wait as the ghost heart begins to mature into a new, beating human heart.
Doris Taylor, director of regenerative medicine research at the Texas Heart Institute at St. Luke’s Episcopal Hospital in Houston, has been working on this— first using rat hearts, then pig hearts and human hearts - for years.
The process is called decellularization and it is a tissue engineering technique designed to strip out the cells from a donor organ, leaving nothing but connective tissue that used to hold the cells in place.
This scaffold of connective tissue - called a “ghost organ” for its pale and almost translucent appearance - can then be reseeded with a patient’s own cells, with the goal of regenerating an organ that can be transplanted into the patient without fear of tissue rejection.
This ghost heart is ready to be injected with a transplant recipient’s stem cells so a new heart - one that won’t be rejected - can be grown.
Science is pretty cool, man.
