Here's a really good one:

Could a hole in space save man from extinction?

"Calculations show that these gigantic machines must be the size of star systems, but this might be possible for civilisations billions of years ahead of ours. Unfortunately, some preliminary calculations show that the wormhole might only be microscopic in size. If so, an advanced civilisation might resort to shooting molecular-sized robots, called 'nanobots', through the wormhole."

Then again, a sufficiently advanced civilization might not settle for molecular surrogates. We should be on the look-out for prospective wormholes -- assuming they're big enough to detect.
