This sounds pretty cool:
According to a report prepared by NASA and California Institute of Technology (Caltech) scientists, an, 'asteroid capture capsule' would be attached to an old Atlas V rocket and directed towards the asteroid between the earth and the moon. Once close, the asteroid capsule would release a 50ft diameter bag that would wrap around the spinning rock using drawstrings. The craft would then turn on its thrusters, using an estimated 300kg of propellant, to stop the asteroid in its tracks and tow it into a gravitationally neutral spot. From here space explorers would have a stationary base from which to launch trips deeper into space. Though NASA declined to comment on the project, it is believed that technology would make it possible within 10-12 years.
NASA declining comment, hm. The /. entry has links to the only two news stories currently in Google, from an Australian paper and the Times of India.
