Perfect Bubbles and Sniffing your way out of Danger.

Dave Ansell

This week on Ask the Naked Scientists we find out the method for a perfect bubble bath, analyse across all species to find the ultimate fighting champion and find out if humans can sniff out danger.

We also look into dietary treatments to aid macular degeneration, look into evolutionary reasons for sensing the presence of ghosts, and investigate treatments to cure the awful pain associated with a trapped nerve.
