Einer Gruppe um Forscher der Technischen Universität München (TUM) ist es als ersten gelungen, mit Labormessungen die Schwankungen der Erdachse zu bestimmen. Sie haben dazu in einem Untergrundlabor den weltweit stabilsten Ringlaser konstruiert, an dessen Verhalten sie Veränderungen der Erdrotation ablesen. Bislang können Wissenschaftler auf die Wanderungen der Polachse nur indirekt über die Richtung zu Fixpunkten im All schließen. Die Lage der Achse und die Drehgeschwindigkeit zu messen, ist Voraussetzung für die exakte Bestimmung einzelner Punkte auf der Erde, etwa für moderne Navigationssysteme. Die American Physical Society hat die Arbeit als Exceptional Research Spotlight eingestuft.
