Headline--: Engineering student cracks major riddle of the universe

My interest here is really in the headline, and the story, which you should read, is as much a human interest story as it is one of scientific discovery.But mainly this is evidence for the way popularizers distort science.

Undergrad finds the missing matter. AND Eng ineering student cracks major riddle of the universe, AND Aussie undergrad, 22, finds the 'missing mass' 

But the smaller print says: An engineering undergraduate in Australia has made a major step forward in solving one of the greatest riddles of the universe: that is, where most of it is.

Just a bit of the article---
Boffins know from observing the universe that it must have a certain amount of mass, otherwise it would have failed to hold itself together as well as it has. Argument continues as to just how well it has or is doing so, but in general astrophysicists are agreed that all the mass we can see – observed galaxies of stars, dust, gas etc – is not enough to account for what's going on. There must be a whole lot more mass out there in some form or another. It is this "missing mass" – or anyway a good chunk of it – that 22-year-old undergraduate student Amelia Fraser-McKelvie, studying Aerospace Engineering at Melbourne's Monash uni, has tracked down.
