We typically think of the senses as being pretty discrete. Sure you can ‘feel a bright color,’ or ‘see a loud necktie,’ but we mostly consider the senses to be separate (unless we’re on acid, or sleep-deprived, or Salvadore Dali). Here’s an example to the contrary, where a photoreceptor gene was found hanging out with a bunch of taste genes. News like this makes us reconsider what it means to see, to hear, and to sense the world in general.

“The new receptor protein, LITE-1, was found among a family of taste receptors in invertebrates [i.e. insects]”
Don’t forget the guy who can see with his tongue. Taste the rainbow!
