Floppies?! The first digital camera I had (a Kodak DC20) had a megabyte of fixed storage, and that was it! We could fit 8 493x373 pics, or 16 320x240 ones! No fancy flash or LCD, either! The only way to get the pictures out of it was through a slow, serial cable at ~50 kbps! At the time, we WISHED we could use big, fast, portable floppies!
Now, kids, get off my lawn!!

That's exactly why I started with "Elop says".

Use the full equation:
E = (mc) + (pc).

If p=0 (p is the momentum; so if you're at rest, p=0), E=mc.
If m=0 (the case for photons, for example), E=pc.

If neither p nor m are zero, E = sqrt(E0^2 + (pc)^2), where E0=mc^2 is the rest energy.

They are reviewing their own paper to make their methods clear. FTFA:

"Dario Autiero of the Institute of Nuclear Physics in Lyons (IPNL), France, and physics coordinator for OPERA, counters that Contaldi's challenge is a result of a misunderstanding of how the clocks were synchronized. He says the group will be revising its paper to try to make its method clearer."

Meaning: Contaldi didn't understand how OPERA did it, and thought they had commited a somewhat stupid mistake. OPERA says they didn't make that error, and that they'll rewrite that part of the paper to make this clear. In other words, this is not news at all.

No. As others said, the Tevatron is just the last stage of a chain of accelerators, one that was used (nowadays) just to collide high energy protons and antiprotons and "see what's inside". The neutrinos come from the previous stage (called "Main Injector"): they used to take a few protons off the beam, collide them into a target in a very well defined direction, focus the muons that come from this, get neutrinos from the muon decay and measure them near the detector and in Minnesota, to get an idea of their oscillation (and now, also of their speed). The experiment that does this is called MINOS, and it doesn't depend on the Tevatron at all. Actually, shutting down the Tevatron will help MINOS: they will get more protons, therefore more neutrinos and more data.

By the way, this is exacly the same general arrangement used by the OPERA experiment (the one with FTL neutrinos), where the neutrinos are produced in CERN and measured there and in Gran Sasso.

Unity is a shell built on top of Gnome 3, so it's impossible for Ubuntu to "drop Gnome" and keep Unity. Their plan is to remove the Gnome-classic shell and replace it with Unity-2D, as you can see on the roadmap; and looks like the plan is still going on.
