In spite of a 10-year multi-billion dollar research effort, hopes of a quick cure for AIDS have been disappointed. Now some researchers are turning to new ideas for fighting the AIDS virus. This photo feature describes four of the most promising of these new approaches: * Gene therapy * New antiviral drugs * Synthetic "antisense" DNA * using a cell receptor, CD26, to prevent the virus taking over human cells in the first place. No one now expects an immediate answer to the AIDS problem. But these techniques may help to solve it in the future.
