There's a reason that many natural things look unbelievably cool: Evolution. Given the stresses of existing on this turbulent spinning orb, some organisms must adapt in literally dazzling ways. Like this alga, which is basically a living opal.

To the best of our knowledge, we humans can only experience this world in three spatial dimensions (plus one time dimension): up and down, left and right, and forward and backward. But in two physics labs, scientists have found a way to represent a fourth spatial dimension.

On Monday, a team of scientists in Australia announced an exciting breakthrough: For the first time, researchers were able to turn light into sound on a microchip. But -- as crazy-sounding new physics applications tend to be -- it's probably going to be a long time before you see one of these chips on a computer you can buy. More importantly, what the heck does "turn light into sound" even mean?
