U2's The Edge plays concert at the Vatican's Sistine Chapel

THE LEAD guitarist from Irish rock superstars U2, The Edge, played "the most beautiful parish hall in the world" last weekend at the Vatican's Sistine Chapel. The performance, the first-ever rock concert in the historic chapel, was given for about 200 doctors and researchers who attended a conference at the Vatican last week on regenerative medicine. The conference discussed the use of adult stem cells to cure difficult and rare diseases such as cancer. The Edge played and sang a cover of Leonard Cohen's "If It Be Your Will" and renditions of U2 songs "Yahweh", "Ordinary Love" and "Walk On". He told a Reuters correspondent, "I can tell this is a really cool audience because normally when I say 'angiogenesis,' eyes glaze over." Angiogenesis is the process through which new blood vessels are formed that feed the growth of tumours. Researchers and scientists are looking for ways to prevent angiogenesis.
