Australian scientists at Queensland University of Technology have developed a material that can be turned from solid to liquid using just light and darkness, in a world-first breakthrough. 

The type of material, which is solid when green light is shone on it but slowly becomes liquid when left in darkness, has been categorised by researchers as Light-Stabilised Dynamic Material, or LSDM. 

The breakthrough material could have important uses in 3D printing and the study of cell biology and is formed using two relatively cheap compounds, meaning the technology can be quickly scaled.
