Like many other more or less closely related animal species, homo sapiens requires rather contiguous gratification in order to stick with doing something continuously which is more involved than low-level life functions such as breathing. Some time after such a one-off news cast, attention would shift away again quite soon. So it would make a short impact, but not a real difference at all. Rather, there would have to be a continuous stream of success stories. (Which would be a remarkable cultural shift in itself, because the sort of news that humans tell each other day in, day out, are predominantly about humanity's conflicts and failures, rarely about its successes.)Just think what 1 national evening news broadcast telling of a find and how everyone could help.
Yet computer simulations, numeric data analysis etc. are generally just tools for the scientific process. It'd be rare for a discovery to identify mere simulations and analyses as a primary reason of its emergence.
