"You create what you could call a natural condom," Short told the Australian Broadcasting Corporation. "You create a biological membrane which the virus can't get through."

Short, a strong advocate of the circumcision of men as a protection against HIV, said he had not yet done tests to prove that the virus was defeated by the keratin cover.

The research, detailed in the Public Library of Science medical journal PLoS ONE, is expected to be tested in clinical trials in Africa. Source Breitbart.com
