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.
Excuse me but we can’t just kill pigs to save human lives. That is wrong.

THEY ARE LITERALLY CALLED FLYING DRAGONS, THAT IS THEIR NAME. OR, IF YOU’RE MORE SCIENCEY, YOU MAY ALSO CALL THEM [DRACO VOLANS], WHICH, BTW, LITERALLY IS JUST ANOTHER WAY OF SAYING FLYING DRAGONS BECAUSE EVEN SCIENCE KNOWS WHEN TO STEP ASIDE AT LET MYTHOLOGY TAKE OVER.
SEE THAT SPINE THING THAT ITS WINGSAILS GROW OUT OF?

it’s so weird that harry potter took place in the 90’s
space jam was being filmed while voldemort was taking over the wizarding world
come on and slam and welcome to azkaban
When I used to think about Voldemort’s horcruxes I imagined a soul divided in equal portions residing in the different horcruxes and Voldemort himself. I realised that this can’t be true in The Half-Blood Prince Slughorn describes making a horcrux as splitting ones soul in two. This means that when Riddle made his Diary into a horcrux he split his soul in half and physically removed one half from his body and placed it in the diary. This means that he only had half of his soul left when he made his next horcrux, Marvolo’s ring. This half would have been split in half leaving only a quarter in Voldemort’s body. This goes on and on the amount of soul remaining in Voldemort halving each time he makes a horcrux until he had only 1/128 or 0.78125% left in his body. As shown in the graph above. So next time you wonder why Voldemort could have done some of things he did, remember how little human he had left in him. I don’t know about you but I think that this is crazy.
Come on guys, I didn’t do maths for 14 notes
So are you telling me that Harry had more Voldemort than Voldemort had Voldemort?
Which is why it changed Ginny so much after the diary incident.
Ohmygoodness. I shouldn’t be laughing this much!
