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.(Source)

In bio today my teacher told me about an experiment she did with plants. When ever she watered them she would take two bottles, yell mean things at one and speak positively to the other. Turns out the one that was watered by the negative water died. Then she reminded us that humans are around 75% water……….If negativity kills plants, what is it doing to teenagers

Can we just take a moment to realize how great that is

I’ve been wanting to make homemade granola bars for a long time. It’s nice to know exactly what’s in your food, especially with something that you eat for energy and a healthy snack.

I’ve been intimidated up to this point by the large amount of ingredients people put in them. I just wanted a basic granola bar: simple to make and inexpensive.

If you want to make them… 

What you’ll need:

1 1/2 cups of rolled oats

1 cup chopped almonds (or other nuts)

1 cup dried cranberries (or other dried fruit)

1/2 cup brown sugar

1/2 cup honey

What you’ll need to do:

Preheat oven to 350. Mix all ingredients. Spread into a well-greased pan. Bake for 10-20 minutes, depending on your crunch preference (the longer it cooks, the crunchier it gets). Let the granola cool before you cut it, or it will fall apart.

Freed

I had myself convinced for so long that this was where I wanted to be in life, what I wanted to be doing, who I wanted to be with.. Until last night. I broke down, it hit me just how lonely I’ve been, how broken and aching and missing I’ve felt. Misplaced, misused, hopeless, downtrodden, miserable, alone and unwanted I’ve felt. So I cried for half an hour while my mind came to terms with this, I cried and cried.. It wasn’t until I heard the door close and smelt the cigarette smoke waft in that I stopped crying. Not only did I stop crying, I felt content. Life made sense. I was happy. There wasn’t a single miserable, depressed thought left in my head. My migraine was gone, my tension was gone. I was giddy, truly giddy. The feeling had me almost hyper, but because I wasn’t tense anymore I just wanted to sink into my mattress and sleep for an eternity. Hours later, and after not enough rest and I still feel kind of buzzed. I know what I want to do, where I want to go. And it’s freeing, I don’t feel trapped by settling for not enough anymore. I don’t care if I sound mean or unappreciative or like a using and abusive bitch, unless you’ve walked in my shoes and been through this shit personally you don’t get a say or opinion.

I am going to go enjoy the birds and a cup of tea and feel alive!

today is my 21st birthday and my first birthday without my twin after he passed away so I made this video as my gift to him (it’s very quiet at the beginning of the song but I get louder than the piano eventually sorry)

#they have the best kisses in any disney thing ever#EVER #because it’s always rapunzel grabbing him and pulling him close #which is GREAT #because her entire character arc is about her seizing the life she deserves#and reveling in every tiny magical moment #and she’s met this boy that she loves#and she’ll be DAMNED if she ever lets him go #SHE EVEN DIPS HIM #SHE DIPS HIM AND KISSES HIM #my daaaaaaarling girl #and the wedding kiss killed me DEAD because eugene’s face is so priceless #he’s still not used to it #he’s still not used to her at all #and he probably never will be 

What really kills me is, in the third gif, her little hops towards him because she is SO EXCITED to marry him and kiss him and share her life with him, she’s just going to grab onto that and hold on forever.  GET IT, RAPUNZEL.

This movie kills me. Their love for each other just makes me so overwhelmed with feels and jealousy.
