Squeezing Blood from a Turnip

My grandmother, when describing the process of attempting to glean truth from a dishonest person, would say: “It’s like trying to squeeze blood from a turnip.”
Seemingly impossible, that.
But consider this: plants and humans have in common some 99% of their DNA.  We humans are, put simply, comprised of the same building blocks as a prickly pear cactus.  The end structure—be it human or plant—is a matter of how the blocks are stacked together.  In some cases, say, comparing the perpetually touchy Kanye West to a thistle, the leap from one thing to the next is not so great.
But what if?
What if we could literally squeeze blood from a turnip, or, instead, from spinach?
Scientists working in several labs recently converted a spinach leaf into what is essentially working human heart tissue.  The network of veins already present in spinach leaves are ideal for such conversion.

  1. Wish they'd find a cure for cancer!

  2. There have been some exciting advances in that. But so much more is needed.
