I think a big part of the problem is an asymmetry of how good things and bad things tend to happen. A terrorist attack might take place in minutes; building a strong community takes years of small efforts, no one of which might be 'newsworthy.'
As a result, I find obituaries to be a great source of 'good news,' rounding up awesome work by an individual that perhaps played out over decades. It would be interesting to see some 'living obituaries' to capture some of this awesome work in a way which lets the perpetrators enjoy it a bit. (I guess major awards do this; but would be cool to see it on a weekly publication scale.)
It's true and I think an other problem is that "uplifting news" generically is kind of a lower common denominator: it's easy to come up with an actual newsworthy information that would be almost universally considered terrible but harder to find something that everybody will find uplifting.
Country X allows abortion? That's going to make people angry. Forbids abortion? Now the rest are angry. A new law that makes polluting more expensive? Surely that's uplifting... unless you have to drive your car for work and you end up losing money because of it. It rains a lot? That sucks. It doesn't rain enough? Now farmers are complaining about the crops.
Completely untainted positive news are hard to come by.
