As new research looks at the financial and environmental case for solar panels in space, we explore how likely the technology could be to power our future energy needs back on Earth.

Marnie Chesterton hears from the author of a new study into the topic, Dr Wei He from King’s College London, and is joined by Professor Henry Snaith from Oxford University to look at the future of solar panel technology.

We also hear from conservation scientist Adam Hart about his views on whether allowing trophy hunting could actually help to protect threatened species in the long term.

Marnie also speaks to the author of one of the books shortlisted for the annual Royal Society Trivedi Book Prize, Simon Parkin. His book, The Forbidden Garden of Leningrad, explores the story of the botanists working at the world’s first seed bank during World War Two, and the extraordinary lengths they went to to protect the specimens they were keeping. We also hear from one of the judges of the awards, the crime writer Val McDermid.

And science journalist Caroline Steel joins us to highlights the week’s most fascinating new pieces of research.
