I've read over this and I can't figure out if they really did create a magnetic monopole from the end of the sphere, or if that field is still coupled with the other side and it's only monopolar in some virtual or mathematical sense? I'm kind of suspecting it is the latter, as a magnetic monopole discovery would overshadow their magnetic tunnel/wormhole work, and it's definitely not the focus of the report.
