It appears that a propane tank exploded at Brookhaven lab.
It's amazing that, of all the things that Brookhaven has, the news just HAD to highlight the "particle accelerator", i.e. RHIC. What does that have anything to do with this blast in the first place? Maybe they want a catchy headline to tie in with the blackhole catastrophe scenario from LHC? If that is so, it is so, so LAME!
BTW, Brookhaven houses MORE than just ONE particle accelerator. There's the accelerator for the NSLS, and there's a research accelerator at the ATF.
