percent of the mass of more complex things like atoms, molecules and everyday objects, from your mobile phone to your pet llama. The vast majority of mass comes from the energy needed to hold quarks together inside atoms. 1.01pm: Cern's live webcast has begun , but the seminar has yet to start. The expressions on some of the faces in the audience suggest Christmas is about to come early for the physics community. 1.02pm: Ok the seminar has started, but traffic to the webcast is obviously heavy, breaking up the transmission. 1.15pm: Still trying to get onto the Cern webcast and failing. This is like trying to buy tickets for the Stone Roses or something. Anyone in the Cern vicinity or who can get online, do tweet me @alokjha or leave a comment below 1.25pm: While Fabiola Gianotti goes through the slides from the Atlas experiment, excluding various energies for the Higgs signal, here are some thoughts from Prof Stephan Sldner-Rembold, head of the particle physics group at the University of Manchester: Atlas and CMS have presented an important milestone in their search for the Higgs particle, but it is not yet sufficient for a proper discovery given the amount of data recorded so far. Still, I am very excited about it, since the quality of the LHC results is exceptional. The Higgs particle seems to have picked itself a mass which makes things very difficult for us physicists. Everything points at a mass in the range 115-140GeV and we
