This neutrino flavor doesn't sound as tasty as the other ones.
Edit:
"Sterile neutrinos could also possibly help explain the matter asymmetry of the universe, or why the universe is primarily composed of matter, rather than antimatter."
Pardon my ignorance, but why would this be? The article doesn't appear to explain at all.
"Physicists and astronomers are looking for sterile neutrinos because they could explain some or even all of the dark matter of the universe,"
That would take a hell of a lot of these sterile neutrinos to explain all of the dark matter. As far as we can tell currently, "regular" neutrinos only account for 0.3% of the total mass/energy-density of the cosmos, while dark matter is a whopping 25%. Might help explain some of the dark matter though, sure.
