Para la ciencia de materiales, la química y la medicina, esto abre la puerta a entender reacciones que ocurren en fracciones de segundo. Todavía no hay aplicaciones cotidianas a la vista, así que el impacto llegará de a poco, a través de herramientas de laboratorio que tardan años en volverse útiles.","quienFirma":"SLAC National Accelerator Laboratory (Departamento de Energía de EE.
