Marie Curie theory of "radioactivity" (a term that she coined), techniques for isolating radioactive isotopes, and the discovery of two elements, polonium and radium. Under her direction, the world's first studies into the treatment of neoplasms were conducted using radioactive isotopes. She founded the Curie Institutes in Paris and in Warsaw, which remain major centres of medical research today. During World War I, she developed mobile radiography units to provide X-ray services to field hospitals.

Marie Skłodowska-Curie Actions promising scientists. MSCA is currently financed through the eighth Framework Programme for Research and Technological Development (called Horizon 2020) and belongs to the so-called 'first pillar' of Horizon2020: "Excellent Science." Through this funding scheme, the Research Executive Agency (REA) has devoted over €6 billion to the Marie Skłodowska-Curie Actions. Since the launch of the programme in 1996, over 100,000 researchers had received MSCA grants by March 2017. To mark this milestone, the European Commission selected thirty highly-promising researchers (who achieved the highest evaluation scores in 2016) to showcase the EU's actions dedicated to excellence and worldwide mobility in research.
