Sea Snakes Regained Color Vision via Rare Genetic Evolution

A new study reveals the annulated sea snake has evolved to perceive a wider range of colors than its ancestors. Early snakes lost their color vision during their adaptation to dim-light burrowing lifestyles, but sea snakes, which inhabit brighter marine environments, regained color vision.

Hot Spots for Vision: Warmer Climates Linked to Eye Health Issues

American seniors residing in warmer regions are more likely to suffer from severe vision impairment compared to their counterparts in cooler areas. The odds of serious vision impairment increased incrementally with the rise in average temperature, with a 44% higher risk for those living in regions averaging 60°F or above.

Mastering Motion: How Our Brains Predict to Perfect the Catch

Researchers shed new light on our brain's ability to predict movement, aiding in seemingly simple tasks like grabbing a moving object. The study found an intricate coordination between vision and motor skills, suggesting that the brain can anticipate movement even with an 80-millisecond delay in response time.
