Yeah, I mean getting the parents to sign an explicit contract and taking a photo of them signing... They were aiming to do the right thing.

You can't use triangulation for anything over a few light-years, the angles are just too acute. And even then, you need to use the full width of Earth's orbit (i.e. repeat a measurement at different times of the year).
I think they just know what the frequency distribution normally is for a burst like this when it is emitted, and use the redshift of the measured frequencies to estimate the distance. Plus they correlate it with the apparent source based on direction (a certain galaxy, in this case, which helped confirm the distance estimate).
You know what you did.
Dread it, run from it...
That really was great, thank you!
No, that's brilliantly executed!
It's called a job. You demoncrats wouldn't know anything about that.

I understand the saliva has a benefit for mosquitoes, but not the swelling and the itching (the "unpleasantness" in the title). In essence, our bodies hung this not-otherwise-useful allergic response on something the mosquitoes couldn't/wouldn't/didn't give up and which was firmly specific to their bites, to single them out.
If there was no saliva our bodies would be pressured by natural selection to pick some other mechanism to make their bites unpleasant. An allergy to their chitin or a phobia to the sound of their wings, etc.
Evolutionary pressure from mosquitoes has probably been no small thing.
