While nanobots that swim through the blood are still in the realm of fantasy, several groups are developing devices a few millimetres in size.

"We believe adverse events such as "disturbance in attention," "memory impairment," "amnesia," "aphasia" and "cognitive disorder" -- even if relatively rare -- will prove to be serious regulatory hurdles for a weight-loss drug. Therefore, we now have reduced conviction in the approvability of Qnexa, and partnering prospects also may be reduced," wrote Cowen analyst Ian Sanderson.
