Scientists gather this week to tackle emerging risks from cutting-edge biotech, echoing the landmark Asilomar conference that shaped genetic engineering safety 50 years ago. What new threats face us, and how can the scientific community stay ahead of them?

Also in the programme: are you feeling asteroid anxiety? We take a closer look at the chances that ‘2024 YR4’ will hit us... We get the latest calculations on this space rock's potential collision course with Earth in 2032.

And, as members of the Royal Society debate whether to expel Elon Musk from their ranks, we explore past fellows who rattled the establishment. Fellows meet next month to decide his fate.

If you want to find out more about the history of genetic engineering - from the Asilomar conference to the present day - search for Matthew Cobb's series 'Genetic Dreams, Genetic Nightmares' on BBC Sounds.
