Gene editing cures blindness--that's the hope behind the news that scientists have restored sight to blind mice. The way they did it validates the science readers find in The Hunt For FOXP5. "The condition, which affects about one in 4,000 people, occurs when a faulty gene causes retinal cells to gradually die off, leading to blindness. The scientists targeted the retinal cells by injecting a virus, carrying a package of gene-editing instructions, into the eyes of blind three-week-old rats."
Instead of revealing the plot, I leave it to readers to find the parallels.
