Professor Roger Short has been promoting lemon juice for HIV/AIDS prevention for several years. Last year he discovered that he had been scooped by Nigerian prostitutes, who have been using it for 10 years. He wants to do a clinical trial, but US federal funding of studies of prostitutes is now banned unless they undertake to give up their profession. So, as he tells Robyn Williams on ABC's Science Show, he decided to launch the Mary Magdalene Project (named after the biblical prostitute) to raise research money.
