MAGNETIC MATERIALS

Multi-channel control of fruit fly behaviour

Nature Materials volume 21, pages 840–842 (2022)Cite this article

Subjects

Fruit flies injected with magnetic nanoparticles and genetically modified to sensitize neural circuits to the rate of change in temperature have enabled subsecond behavioural responses to magnetic stimuli and multi-channel magnetic control.
