a decellularized “ghost” heart

How cool is it that when you take all the cells out of an organ it still looks like an organ?

I remember when I was in high school and still very confused about how tissues worked, because all anyone taught me was that we’re made up of piles of cells hung on bones.  But that’s not how it is!  Cells build themselves little hammocks of polymer and densely branched glycoproteins; we’re like onions, layers of membrane over tough rubbery collagen, huge protein scaffolds cradling slippery organs.

Bodies are not made of cells — bodies are made by cells.

That was the coolest explanation I’ve heard


“I ran away when I was about sixteen. I’d had enough…I hated the lot of them: my parents with their pure-blood mania, convinced that to be a Black made you practically royal…my idiot brother, soft enough to believe them…They thought Voldemort had the right idea, they were all for the purification of the wizarding race, getting rid of Muggle-borns and having pure-bloods in charge.”
