(Newser) – Who needs fingerprints when an invisible bacteria cloud might do? It's among the week's notable discoveries:

  • You Have an Invisible Cloud, and It's Gross: When someone says you're in their personal bubble, they aren't exactly speaking metaphorically. University of Oregon researchers say they've found people really are surrounded by a sort of cloud that's unique to them. The gross part?

  • Graves of Utah Victims From 1857 Massacre Found: An archaeologist believes he's found the true resting place of the victims of the Mountain Meadows Massacre—more than 150 years after the killings. Members of the Mormon church slaughtered the travelers in a wagon party during a time when hostility against non-Mormons in Utah was high.

But University of Vienna researchers now say they've determined that giraffes do indeed "produce vocalizations"; here's what those vocalizations sound like.
