the sum of all fears is to create a brand new virus. that would be the end of us. steven king talked about this in a book, I think. but on the ohter hand, we could also produce a anti-virus agent more easily with this technoligy, right? let's put our focus on that, if you scared to dead. :) cheers mark

If you took a virus as lethal as Ebola and engineered into it the contagiousness of the Rhino virus (or common cold), could a cure even be devloped before it spread all over the world? But all this is assuming these parts are even compatible. Viruses are so small that relatively minor changes can completely alter their individual characters. It's not even like combining apples and oranges. It may be more like combining a door with a swimming pool--would hybrid be as useful as either one?

Yes, I think such a simple chemical machines cannot be recombined easily. But each virus has a certain strategy. Let's say, it would be possible maybe combining these strategies. Like, binding and invading to more human cell types, knockin off immunity, resistance to air... I thought Ebola is very fast, thats why it will never be a global threat to the world. We know when the enemy is attacking us and cen defend ourselves. Unlike HIV, which waits years before it strikes, and we are unaware of anything wrong. That is much more dangerous, I think.
