In this episode of RAZOR, we investigate how personalised treatment using zebrafish larvae could help in cancer treatment and get to grips with a new way of storing energy in the form of liquid air.

In Lisbon, Emma Keeling visits Professor Rita Fior and her team at the Champalimaud Centre for the Unknown, who are working on a more personalised treatment of cancer using zebrafish larvae which help assess which is the best treatment to use.

Shini Somara visits the University of Birmingham to meet Professor Yulong Ding who has developed a way to store surplus renewable energy as liquid air. It can then be expanded from a liquid back into a gas through electricity-generating turbines when it is needed.
