Spineless sea squirts shed light on vertebrate evolution, and an iodine-fuelled engine powering a satellite in space.
In this episode:
00:45 A story of sea squirts, ancient vertebrates and missing genes
When a PhD student set out to study the developmental pathways of a strange sea creature, he hoped to shed light on the origins of vertebrate animals. Instead, researchers found themselves investigating a strange case of missing genes. We hear why gene loss could be a more significant factor in evolutionary processes than was previously thought.

10:43 An iodine-fuelled engine for satellites
In space, many satellites use xenon-fuelled ‘electric propulsion systems’ to maneuver. However, xenon is rare and requires high-pressure storage systems, so researchers have been working to develop alternative fuels. This week, a team publish details of the first in-space test of an iodine-powered electric propulsion system, which they say has many advantages over xenon systems.

The meeting between superpower presidents was cordial and careful, but it will take far more than a video call to smooth such frosty relations.
Europe once had an enviable international rail network—one it must revive if the bloc is to meet its climate targets. And the costly and sometimes dangerous lengths South Koreans are going to for flattering photographs.
