The Large Hadron Collider at CERN was built to discover new life forms and new civilizations particles to complete the Standard Model of physics, of which the Higgs-Boson is only a part. The $5 billion project has finally found something previously unseen, according to the BBC. ATLAS has picked up Chi-b 3P: a Boson (building block of nature) Meson comprised of a "beauty quark" and a "beauty anti-quark," bound together with a strong nuclear force -- believed to exist in nature, but never seen until now. Yesterday's discovery is so new, it hasn't even had a sigma rating yet, but we don't expect CERN to confirm the find until its next two hour keynote.
Update: The initial report described the particle as a Boson (elemental force carriers), it is in fact a Meson (which comprise of a quark and an anti-quark).
