Step Aside, WIMPs!

Two of the world's most massive detector projects--China's PandaX-II collaboration and the US's LUX group--have ended up empty-handed in their search for weakly interacting massive particles (or WIMPs), long considered one of the most plausible explanations for our galaxy's surprising rotational behavior.In anew paper from the LUX l...
