Liveblog: CERN Announcement on the Higgs Boson

The Guardian is doing the honors:
1.56pm: Via the Science Media Centre, Dr Claire Shepherd-Themistocleus, head of the CMS group at the STFC Rutherford Appleton Laboratory, said: "We are homing in on the Higgs. We have had hints today of what its mass might be and the excitement of scientists is palpable. Whether this is ultimately confirmed or we finally rule out a low mass Higgs boson, we are on the verge of a major change in our understanding of the fundamental nature of matter."
(Also: Hooray, I can hear the webcast properly! Well done for inventing the web, Cern folk, and also for sorting out your IT)

1.49pm: Fabiola Gianotti has finished her presentation. So far,we know that Atlas seems to have found evidence for a bump around 126GeV for something that looks like the Higgs.
Next up is Guido Tonelli, spokesperson for Cern's other main detector, the Compact Muon Solenoid (CMS). As @iansample says, "So. What we're looking for now is whether CMS detector has seen Higgs-like signals around the same mass (126GeV)."

Here's CERN's explanation of what they do:
