The world's thinnest spaghetti is 200 times thinner than a human hair, which means you'd have a hard time eating it. It's actually a nanofiber developed to help heal wounds. Besides, you'd probably overcook it in a second anyway.

Contact lenses get pretty thin nowadays, but they’ve got nothing on a new lens from scientists at Stanford and the University of Amsterdam. The team has created the world’s thinnest lens, measuring just three atoms thick.

Great insights have been gathered recently into the genetic drivers underpinning obesity, but little has focused on genes related to thinness. A new study has identified one gene that seems to play a role in promoting thinness in humans and animals.

Researchers have developed a flat lens that's one one-thousandth the thickness and one one-hundredth the weight of a conventional model.
