#Eyemovements

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).

A recent breakthrough study has discovered that the eyes, far from being mere passive players during sleep, actively orchestrate how our brains consolidate memories—guarding old knowledge while seamlessly incorporating new information. These findings, published by a Cornell University research team and highlighted in The Brighter Side of News on April 21, 2025, suggest that subtle changes in the pupil during sleep play a pivotal role in preventing memory “mix-ups” and could one day revolutionize how we learn, remember, and perhaps even treat memory disorders (The Brighter Side of News).
