Researchers create a working human lung on a microchip

Sometimes, scientists create something that is so amazing, my puny brain has trouble wrapping itself around the news. This is one of those times: researchers at Harvard have created a functional, respirating human lung on a chip.

The little chip, which is coated in blood and lung cells, acts just like our lungs do: it exchanges gas between said lung cells and blood cells, allowing for oxygen to get into the bloodstream and keep us, you know, alive. It's tiny, and but a fraction of the size of a real lung, but it's a big step towards repairing and replacing faulty organs in people with lab-made functional organs.

So I guess it's officially the future, eh?
