In "Pain", one of the Air Force members becomes erratic with the belief that there are snakes underneath his skin. Scary enough a thought on its own, when recalling what the Air Force dealtwithbefore, one begins to understand just how horrific that scenario would be.
Of course the inhabitants of Novus have a cure for Motor Neuron Disease. A sizable portion of the population is descended from TJ after all, thus it must have been a lot more common on Novus than on Earth.
Not to mention, of course they would have a greater understanding of genetics than we do. Due to their entire population being derived from less than 80 people, they would have been forced to find ways to sustain their population through genetic engineering, otherwise the genetic bottleneck would have caused them to interbreed themselves into extinction within a few generations.
And, they started out with all of the knowledge that their ancestors could record. Due to the aforementioned inbreeding issue (and certainly someone in the group would understand the 50/500 rule) genetics would have been a high priority. Then add a couple thousand years of development, even despite having to bootstrap their infrastructure before they could actually advance the sciences.
