Yesterday, we revealed that a new spider, Aptostichus bonoi, has been named after U2 singer Bono. The trapdoor spider can be found in the Joshua trees of California - and of course U2's seminal 1987 album was called The Joshua Tree. But why? Broadcaster and RTÉ 2fm legend Dave Fanning joins us in studio for the definitive reason for the album title!

There's also no doubt that she is as equally known and loved for her buxom bosom! We can all be very flippant about breasts. After all, most of us have had a relationship with them dating back to our infancy! But for many women, a hugely prominent set of breasts is far from a laughing matter.

We asked Donal O'Donoghue, Features Editor with the RTÉ Guide, to come in today to talk us through the best and worst of autobiographies!
