Editor's note

Just as a global summit on gene editing starts in Hong Kong, world researchers seem dismayed about reports a Chinese scientist has edited human embryos using CRISPR technology – and that genetically-modified twin baby girls are now born as a result. Dimitri Perrin and Gaetan Burgio talk through what we know and don’t know about this development, and Joyce Harper says this technology is untested in humans, making the development premature, dangerous and irresponsible.

And NASA’s Insight Lander has arrived safely on Mars! Paulo de Souza writes it’s the latest step in humanity’s long fascination with the red planet.
