A team of nanoscientists in the UK say they've created "the world's smallest violin." Narrower than the width of a human hair, it boasts equal parts meme and engineering potential, and is a cheeky proof of concept of a cutting-edge approach to designing structures at the smallest scales that humans can possibly tinker at. But if you were picturing a nano-sized Stradivarius, think again. What the researchers have actually created is a microscopic image of a violin etched on to the surface a little chip, and not a playable instrument. That said, it's still an impressive achievement.
