This was published in the New Scientist in early 2005 (despite what the dateline says), and I think there have since been several followup papers that fail to replicate Ennis' homeopathy findings.
I'm sure someone will get all emotional when I say this, but I'm actually amazed that people waste time with homeopathy... and I'm outraged that the NHS takes it seriously.
Anyway, several of these fascinate me, like the Kuiper cliff, the Pioneer anomaly, and cold fusion. With the latter especially it seems clear something is going on, we just don't know what.
