He says it's relatively easy to make membranes that can filter the bacteria out of water.

We've always been told that magnets have two poles, north and south. But theory suggests there should be something called a magnetic monopole, a magnet that has either a north pole or a south pole but not both of them. So far no one has found this elusive magnetic monopole.<p>As part of his project, Joe's Big Idea, NPR's Joe Palca brings us the story of scientists at Amherst College in Massachusetts. They have created a synthetic magnetic monopole.

For the past 31 months, the spacecraft has effectively been asleep. Most of its instruments were shut off to save energy, including the radio for communicating with Earth. Mission managers can now start preparing Rosetta for a rendezvous with a comet later this year. NPR's Joe Palca has more.<p>JOE PALCA, BYLINE: Rosetta went into hibernation in June 2011.
