A baby born with a rare and dangerous genetic disease is thriving after getting an experimental gene editing treatment made just for him. Researchers said the Pennsylvania boy is among the first to be successfully treated with a custom gene editing therapy. They described his case in a study published on Thursday in the New England Journal of Medicine. Though it may be a while before similar personalized treatments are available for others, doctors hope the technology can someday help millions who have been left behind by genetic medicine because their diseases are so rare.

NASA's Perseverance rover has detected the first aurora at Mars that's visible to the human eye. That's good news for future astronauts who can savor the view on the red planet. European and U.S. scientists reported Wednesday that the green aurora in the dusty Martian sky was generated by a solar storm and had three days' advance notice last year to set aside viewing time. The researchers say this shows that forecasting of northern and southern lights is now possible at Mars. Previous auroras observed at Mars appeared only in the ultraviolet. This one was in the visible wavelength.
