If the field is disturbed enough to cause the superconducting coils to heat up enough, the heat from the resistance will cause the cryogen to evaporate, and the field will collapse, releasing all of the energy in the coils. The net result is you'll have most of the liquid nitrogen and helium go from liquid to gas over the course of 15 - 30 seconds. (Fortunately, modern magnets have release valves or other mechanisms to release the gas, otherwise the pressure could build up to dangerous levels.) The danger, besides losing you field, is that the evaporated cryopgens can displace all the oxygen in the room.

Check out this demo of a quench (Need the quicktime plugin to see it) It's near the bottom of the page:

A new technique could let biologists better see how proteins fit together and make life happen.

Yes, but can it see my favorite planet?

IBM is also supplying the chips to enable fast 3D reconstruct of MRI images as well. Pretty cool stuff from about 1:40 on in this video.
