A New Yorker article by Rivka Galchen details the discovery of "olo," an extraordinarily vibrant blue-green hue previously unseen by the human eye. Researchers produced this "greenest green" by using targeted laser technology to directly stimulate specific retinal cone cells. Because standard screens and digital media cannot capture or reproduce this color, the breakthrough expands the limits of human visual perception and holds promising potential for future treatments for color blindness.

The Marvel Universe
The serialized storytelling that the Marvel Cinematic Universe has adopted came from Stan Lee's vision to make comic writing, and character creation, collaborative. No one person was responsible for any one comic. Writers and artists worked together and bounced ideas around, and only then, could a new hero spring to life. A marvelous story.
