Stories of bionic limbs doing this or that for people never ceases to brighten up my day. Here's another: Britain's Chloe Holmes, 15, lost her fingers at a very young age. Now, she's get a brand new pair, and they're just about as good as anyone else's.
Researchers at Vanderbilt University in Tennessee have paired both a powered knee and ankle, working in tandem, to create a bionic limb that is just about as good as the original. It's the first prosthetic limb to use said motorized joints in conjunction, and the results are impressive to see in motion.
