Like any law-abiding train passenger, a molecule called oskar RNA carries a stamped ticket detailing its destination and form of transport, scientists have found. They show that for this molecule, moving in the right direction isn’t enough: speed is of the essence. Their study also provides clues as to how a single molecule could receive tickets for different destinations, depending on what type of cell it is in.
