So there was this article published today that some researchers may have found a dark matter signature emanating from the sun in the form of xr-ray emission from axion interactions with Earth's magnetic field.
Article: http://www.theguardian.com/science/2014/oct/16/dark-matter-detected-sun-axions
Paper: arxiv.org/abs/1403.2436
Wikipedia quote: "Axions are predicted to change to and from photons in the presence of strong magnetic fields, and this property is used for creating experiments to detect axions."
How can a particle interact with a magnetic field without having an electric charge? I assume it must be some strong/weak interaction, but how does that work?
