Re: How come there are no beneficial diseases?

Well, there are engineered pathogens with beneficial effects. Look up CRAds (Conditionally Replicating Adenoviruses) - basically the adenoviruses have restricted replication (and often lysis as well) within healthy cells, but not within tumors. The viruses preferentially kill cancerous cells over no...

The E=mc2 fusion group has a publishing embargo imposed by the DoD.

They aren't allowed to discuss specifics of their results.
