The world’s first CRISPR babies are now toddlers. Now, nearly four years since the super-controversial experiment was announced, scientists in China want to set up a healthcare institute specifically to look after the three children. The team examines the ethics of it all.

Humans thrive at particular temperatures, and that’s why we live where we live. But these areas of optimal climate are shrinking because of climate change. As we’re on course to hit 2.7 degrees of warming by the end of the century, the team finds out what will happen to future populations. And with the UN Ocean Conference taking place, we hear a clip of Sounds of the Ocean by composer Joshua Sam Miller, a piece where the lead singer is a whale!

Rogue planets, roaming through space without a star of their own, may still be able to host life. Even without the heat of their own Sun, the team explains how there is still a way that life could thrive.
