Science: A group of physicists has succeeded in using a pipe of laser light to transport a tiny particle one meter and set it on a surface with a precision of less than the width of a human hair. Science‘s Adrian Cho discusses the physics involved and the research of two different university groups, one at the University of Glasgow in the UK and the other at Australian National University. Such a technique could have multiple applications, such as to simulate the physics of interstellar space or sniff out airborne traces of contraband.
