For a bit of good news today, we have this:
German researchers have opened a door to a potential new AIDS drug with the discovery of a small protein circulating in human blood that blocks multiple strains of HIV, even those resistant to existing medications.
This natural anti-HIV factor — a chain of 20 amino acids known as a peptide — interferes with a feature on the surface of the AIDS virus that otherwise allows the virus to penetrate the membrane of cells it is about to infect, a process known as fusion.
