A new scientific breakthrough has revealed the ultimate limit of human visual speed, finding that how quickly we can “see” moving objects is not just about our eyes, but intimately linked with how our eyes move. The research, published in Nature Communications on May 8, 2025, uncovers for the first time how the mechanics of saccades—our rapid, darting eye movements—set the boundaries on what we can perceive in fast motion, challenging long-held beliefs about the biological constraints of sight and reshaping our understanding of tasks ranging from sports performance to everyday perception (Nature Communications).

Imagine being able to perceive a color that no human has ever seen before—a jump in our sensory experience that until now has belonged only to science fiction. This is exactly what a groundbreaking team of engineers, computer scientists, and ophthalmologists at the University of California, Berkeley, in collaboration with experts from the University of Washington, claim to have achieved. In recently published research in the journal Science Advances, these scientists reveal that by precisely targeting specific cells in the human retina, they have enabled volunteers to see a novel color, which the team dubbed “olo” (MedicalXpress).
