News: Imperial at COP26 and previewing the Great Exhibition Road Festival – We hear about Imperial’s priorities for the upcoming COP26 climate change summit, and find out what’s happening at the new hybrid Great Exhibition Road Festival, for which this year’s theme is ‘one world’.

Solving climate injustice – We meet two researchers from Imperial and the Royal College of Art trying to tackle climate injustice – where those who have contributed the least to climate change face the worst impacts – through design and finance.

You can hear more from the experts in a panel discussion at the Great Exhibition Road Festival, in-person and streamed online, on Saturday 9 October.

The climate crisis and mental health – We hear all the ways climate change itself, and worries about the future, can affect mental health, and discuss how people can deal with these issues including building a better future.

A new way to do quantum computing – We meet Physics Professor Terry Rudolph, who co-founded a company called PsiQuantum that is building quantum computers in a new way, and has just received a multi-billion-dollar valuation.

You can also listen to an extended version of this interview.
