Not exactly "news" (it's two years old), but it's an interesting scientific paper relevant to our interests here
Stability of the Distant Satellites of the Giant Planets in the Solar System, by Shen and Tremaine (2008),
http://iopscience.iop.org/1538-3881/136/6/2453 Fortunately it's in a free issue of the Astronomical Journal, so you can grab the PDF for free! I've only skimmed it so far, but the very interesting thing is that it says that there can be stable satellite orbits
outside the planet's Hill Sphere, which I at least wasn't previously aware of. So check it out if you're interested!
