"You always take the sweetest rose and crush it until the petals fall..."
"No relationship is perfect, ever. There are always some ways you have to bend, to compromise, to give something up in order to gain something greater…The love we have for each other is bigger than these small differences. And that’s the key. It’s like a big pie chart, and the love in a relationship has to be the biggest piece. Love can make up for a lot."

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.
This is the coolest fucking thing ever. Science, man. Fucking science. Shit completely blows me away.
"The assumption that work is a passport to dignity and security, that work is what makes life worth living, is so deeply embedded in our culture that it is almost heretical to think otherwise. But the problem isn’t just the lack of work. It’s also the lack of hope. Young people leaving school and university can no longer kid themselves that their future is likely to include a stable place to live, love and get on with growing up, even if they do manage to find paid work.
Here’s what is notably not being said to the young and desperate: you are more than your inability to find a job. Your value to a potential employer is not the sole measure of your worth as a person. If you can find only precarious, exhausting, depressing work, or if you can’t find work at all, that doesn’t mean you are useless, lazy, or a “waste of space”."
