Physicists detected a hybrid particle that is a mashup of an electron and a phonon, 'glued' together with an exceptionally strong bond. It may be possible to tune the two components in tandem, enabling scientists to apply voltage or light to a material to tune not just its electrical properties but also its magnetism.

Marine life hitching a ride on ocean-crossing ships poses a threat to Antarctica's pristine ecosystems, with the potential for invasive species to arrive from almost anywhere across the globe, say the authors of a new study.
