science π¦ 400-year-old shark's eyes aren't aging out
New research suggests that Greenland sharks maintain their eyesight despite their extreme longevity. Scientists found that a DNA repair mechanism helps these ancient fish prevent retinal degeneration. The sharks examined were caught between 2020 and 2024 near Disko Island, Greenland. Their visual systems are also uniquely adapted to the low light of the Arctic habitat. This discovery could offer new clues for preventing age-related vision loss in humans. π§
