Null result reported from XENON100 experiment on Cold Dark Matter detection attempt.
Xenon100 reports no CDM detection
Parameter space starts groaning as it is squeezed tighter...
Definitely not croquet...

There's a minor kerfuffle at the moment over the XENON experiment's early data (arxiv paper) which did not detect any dark matter in 11 days of data acquisition.
"All the evidence, experimental and even a little theoretical, seems to indicate that it is the energy content which is involved in gravitation, and therefore, since matter and antimatter both represent positive energies, gravitation makes no distinction." -Richard Feynman
One thing seems certain, though: this is tough news for LHC...
Finally! Personally I'm pleased with a null detection because I'm currently in the "GR has issues" camp.
Tough news for LHC? Why? main experiments there aren't focused on this area. Plus this actual extends some limits from LHC. I don't see a lot of issues.
