Roland Piquepaille writes "In the nanotech world, molecular 'motors' have been heavily investigated during the last decade. And you probably read that these nano-carriers will one day be able to move a useful drug right where it's needed inside your body. But think for a minute to the size gap between yourself and a molecule. It's pretty impressive! Now, according to this news release, researchers from the Max Planck Institute of Colloids and Interfaces in Germany have developed a theory stating that only a few motor molecules should be enough for directed transport over centimeters or even meters. It's probably a meaningless comparison, but it's like if you were able to walk to the moon and come back."
