[1007.1150] Event Excess in the MiniBooNE Search for $\bar
Posted: November 04 2010
New MiniBooNE results now show some hints of sterile neutrinos!

I nearly missed this due to its understated title and abstract that don't even allude to the possible cosmological significance, but this could be very interesting for cosmology if sterile neutrinos could be dark matter.
In 2007 MiniBooNE announced their oscillation results from a neutrino beam were not consistent with LSND, which disfavored sterile neutrinos. But recently (well, last summer, but I am a bit behind on particle physics news, apparently) they announced results using an antineutrino beam that DO support the LSND results. Maybe there are sterile neutrinos after all?
I don't think the case is rock-solid yet, but we cosmologists should definitely be paying attention to this!
