Computers: Powerful Allies in Fight Against AIDS

Computers: Powerful Allies in Fight Against AIDS

Effective treatment of HIV-virus is a race against time: Many of the drugs that have been potent killers of HIV-virus, have today lost their power, because the virus has become resistant to them. As a result science must constantly develop new drugs that can attack the virus in new ways.   Now researchers from the [...]
