Astronauts show how CRISPR gene editing works in space

CRISPR gene editing is no longer confined to Earth. Astronaut Christina Koch and scientists have successfully demonstrated CRISPR-Cas9 in space for the first time, using it as part of a new technique to damage DNA and study how it repairs in microgravity. "Technical and safety concerns" had prevented earlier studies like this, according to the researchers. The experiment produced a particularly damaging double-strand DNA break in a yeast cell culture aboard the International Space Station. Koch ...
